Progestogen only contraception in women with congenital heart disease

BACKGROUND

There is little information of progestogen-only contraceptives in patients with congenital heart disease (CHD) on the long-term.

OBJECTIVE

To evaluate the use of contraception in patients with CHD. We studied both short-acting reversible contraceptives (SARCs), oral progestin-only pills (POPs) and long-acting reversible contraceptives (LARCs): intrauterine devices (IUD-IPs) and subdermal implants both impregnated with progestogens (SI-IPs).

STUDY DESIGN

Retrospective study of all women attending the preconception clinic. Contraceptive methods were classified in three TIERs of effectiveness before and after consultation. ESC classification regarding pregnancy risk, WHOMEC classification for combined oral contraceptive safety was collected.

RESULTS

Six hundred and fifty-three patients. A significant proportion of them switched from TIER 3 to TIER 2 or 1 (p < .001) after consultation. One hundred and ninety-nine patients used POPs, 53 underwent IUD-IPs implantation and 36 SI-IPs, mean duration was 58 ± 8, 59 ± 8 and 53 ± 38 months, respectively.

CONCLUSIONS

Because of their safety and efficacy, IUD-IPs and SI-IPs should be considered as first-line contraception in patients with CHD.

Non-invasive Estimation of Pressure Drop Across Aortic Coarctations: Validation of 0D and 3D Computational Models with In Vivo Measurements

Blood pressure gradient ( Δ P ) across an aortic coarctation (CoA) is an important measurement to diagnose CoA severity and gauge treatment efficacy. Invasive cardiac catheterization is currently the gold-standard method for measuring blood pressure. The objective of this study was to evaluate the accuracy of Δ P estimates derived non-invasively using patient-specific 0D and 3D deformable wall simulations. Medical imaging and routine clinical measurements were used to create patient-specific models of patients with CoA (N = 17). 0D simulations were performed first and used to tune boundary conditions and initialize 3D simulations. Δ P across the CoA estimated using both 0D and 3D simulations were compared to invasive catheter-based pressure measurements for validation. The 0D simulations were extremely efficient ( ∼ 15 s computation time) compared to 3D simulations ( ∼ 30 h computation time on a cluster). However, the 0D Δ P estimates, unsurprisingly, had larger mean errors when compared to catheterization than 3D estimates (12.1 ± 9.9 mmHg vs 5.3 ± 5.4 mmHg). In particular, the 0D model performance degraded in cases where the CoA was adjacent to a bifurcation. The 0D model classified patients with severe CoA requiring intervention (defined as Δ P ≥ 20 mmHg) with 76% accuracy and 3D simulations improved this to 88%. Overall, a combined approach, using 0D models to efficiently tune and launch 3D models, offers the best combination of speed and accuracy for non-invasive classification of CoA severity.

Impact of relationship status on psychological parameters in adults with congenital heart disease

Objective

Adult congenital heart disease (ACHD) is a growing disease entity, posing questions concerning psychosocial outcomes across the lifespan. Spousal relationships were shown to benefit cardiovascular and mental health in the general population. We assessed the association of relationship status with anxiety and depression in ACHD patients and determined whether patients considered disease-related concerns potential mediators of relationship problems.

Methods

N = 390 ACHD patients were included. Self-report questionnaires were used to assess relationship status, ACHD-related relationship problems, socio-demographic variables, and depression and anxiety scores. Further, clinical parameters concerning the heart condition were determined.

Results

N = 278 (71%) patients were currently in a relationship, while N = 112 (29%) were not in a relationship. Groups did not significantly differ regarding age, sex, and cardiovascular parameters. Two-way MANCOVA with relationship status and sex as independent variables, controlling for age, NYHA class, and NT-proBNP, showed an association of relationship status with depression, while sex was associated with anxiety. N = 97 (25%) patients reported disease-related adverse effects on a current or prior relationship. In detail, worries about body image (N = 57, 61%), own fears (N = 51, 54%), problems arising from wish to have children (N = 33, 35%), fears regarding a joint future (N = 29, 31%), partner's fears or lack of understanding (N = 28, 30%), and sexual problems (N = 21, 22%) were cited.

Conclusion

Relationships status was associated with depression, while sex was associated with anxiety in ACHD patients. Relationship status as well as potential relationship problems, and the importance of social support for mental and physical well-being, should be considered when treating ACHD patients.

Evolution of Value in American College of Cardiology/American Heart Association Clinical Practice Guidelines

BACKGROUND

In January 2014, the American College of Cardiology/American Heart Association released a policy statement arguing for the inclusion of cost-effectiveness analysis (CEA) and value assessments in clinical practice guidelines. It is unclear whether subsequent guidelines changed how they incorporated such concepts.

METHODS

We analyzed guidelines of cardiovascular disease subconditions with a guideline released before and after 2014. We counted the words (total and per page) for 8 selected value- or CEA-related terms and compared counts and rates of terms per page in the guidelines before and after 2014. We counted the number of recommendations with at least 1 reference to a CEA or a CEA-related article to compare the ratios of such recommendations to all recommendations before and after 2014. We looked for the inclusion of the value assessment system recommended by the writing committee of the American College of Cardiology/American Heart Association policy statement of 2014.

RESULTS

We analyzed 20 guidelines of 10 different cardiovascular disease subconditions. Seven of the 10 cardiovascular disease subconditions had guidelines with a greater term per page rate after 2014 than before 2014. Across all 20 guidelines, the proportion of recommendations with at least 1 reference to a CEA changed from 0.44% to 1.99% (P<0.01). The proportion of recommendations with at least 1 reference to a CEA-related article changed from 1.02% to 3.34% (P<0.01). Only 3 guidelines used a value assessment system.

CONCLUSIONS

The proportion of recommendations with at least 1 reference to a CEA or CEA-related article was low before and after 2014 for most of the subconditions, however, with substantial variation in this finding across the guidelines included in our analysis. There is a need to organize existing CEA information better and produce more policy-relevant CEAs so guideline writers can more easily make recommendations that incentivize high-value care and caution against using low-value care.

Consistency of the continuous flow pressure gradient despite aortic arch anomalies co-existing with coarctation

Aims

Severity assessment for coarctation of the aorta (CoA) is challenging due to concomitant morphological anomalies (complex CoA) and inaccurate Doppler-based indices. Promising diagnostic performance has been reported for the continuous flow pressure gradient (CFPG), but it has not been studied in complex CoA. Our objective was to characterize the effect of complex CoA and associated hemodynamics on CFPG in a clinical cohort.

Methods and Results

Retrospective analysis identified discrete juxtaductal (n=25) and complex CoA (n=43; transverse arch and/or isthmus hypoplasia) patients with arm-leg systolic blood pressure gradients (BPG) within 24 hours of echocardiography for comparison to BPG by conventional Doppler indices (simplified Bernoulli equation and modified forms correcting for proximal kinetic energy and/or recovered pressure). Results were interpreted using the current CoA guideline (BPG ≥20 mmHg) to compare diagnostic performance indicators including receiver operating characteristic curves, sensitivity, specificity, and diagnostic accuracy, among others. Echocardiography Z-scored aortic diameters were applied with computational stimulations from a preclinical CoA model to understand aspects of the CFPG driving performance differences.Diagnostic performance was substantially reduced from discrete to complex CoA for conventional Doppler indices calculated from patient data, and by hypoplasia and/or long segment stenosis in simulations. In contrast, diagnostic indicators for the CFPG only modestly dropped for complex vs discrete CoA. Simulations revealed differences in performance due to inclusion of the Doppler velocity index and diastolic pressure half-time in the CFPG calculation.

Conclusion

CFPG is less affected by aortic arch anomalies co-existing with CoA when compared to conventional Doppler indices.

Coarctation of the Aorta: Modern Paradigms Across the Lifespan

While coarctation of the aorta varies greatly in both severity and age at presentation, all patients are at increased risk of hypertension both before and after repair. Despite advances in knowledge about genetic etiologies, pathophysiologic mechanisms, and optimal repair strategies, patients with repaired coarctation of the aorta remain at increased risk of acquired cardiovascular disease. The aims of this review are to describe the management of coarctation of the aorta at all ages before and after repair, highlight pathophysiologic mechanisms of hypertension, and review long-term follow-up considerations.

Non-invasive estimation of pressure drop across aortic coarctations: validation of 0D and 3D computational models with in vivo measurements

Purpose

Blood pressure gradient (Δ P ) across an aortic coarctation (CoA) is an important measurement to diagnose CoA severity and gauge treatment efficacy. Invasive cardiac catheterization is currently the gold-standard method for measuring blood pressure. The objective of this study was to evaluate the accuracy of Δ P estimates derived non-invasively using patient-specific 0 D and 3 D deformable wall simulations.

Methods

Medical imaging and routine clinical measurements were used to create patient-specific models of patients with CoA (N = 17 ). 0 D simulations were performed first and used to tune boundary conditions and initialize 3 D simulations. Δ P across the CoA estimated using both 0 D and 3 D simulations were compared to invasive catheter-based pressure measurements for validation.

Results

The 0 D simulations were extremely efficient (~15 secs computation time) compared to 3 D simulations (~30 hrs computation time on a cluster). However, the 0 D Δ P estimates, unsurprisingly, had larger mean errors when compared to catheterization than 3 D estimates (12.1 ± 9.9 mmHg vs 5.3 ± 5.4 mmHg). In particular, the 0 D model performance degraded in cases where the CoA was adjacent to a bifurcation. The 0 D model classified patients with severe CoA requiring intervention (defined as Δ P ≥ 20 mmHg) with 76% accuracy and 3 D simulations improved this to 88%.

Conclusion

Overall, a combined approach, using 0 D models to efficiently tune and launch 3 D models, offers the best combination of speed and accuracy for non-invasive classification of CoA severity.

Left Coronary Artery to Pulmonary Trunk Fistula: Two Case Reports With Literature Review

Coronary artery fistulas (CAFs) are abnormal communication between coronary arteries and the pulmonary trunk or with adjacent heart structures. Coronary pulmonary artery fistulas (CPAFs) can be congenital or acquired. Mostly, CAFs are found as incidental findings on angiographic evaluation. The management of CPAFs varies from case to case depending on size, anatomical location, patient's clinical presentation, and presence of coronary steal phenomenon. We present two cases of CPAFs; one of them had coronary steal phenomena at a young age with no past medical history of coronary artery disease, and the patient underwent transcatheter coil embolization to close the fistula. In other cases, a fistulous connection between the left anterior descending (LAD) and the pulmonary trunk was found incidentally on computed tomography (CT) of the heart and based on a small-sized fistula and symptomatic improvement, the patient was discharged with conservative management. CPAFs are rare cardiac anomalies but can give rise to severe hemodynamic complications, so this should be a part of the initial differential diagnosis if the patient does not have significant coronary artery disease. Percutaneous closure or surgical correction is indicated if the patients are symptomatic or have secondary complications.

Experience of Percutaneous Closure of Ventricular Septal Defects in 140 Patients With Different Duct Occluders in a Tertiary Care Rural Hospital in Central India

Background Ventricular septal defects (VSDs) are the most common type of septal defects in early infants and are very complicated. This has paved the way for the development of new minimally invasive procedures for interventional cardiologists. This study presents our experience using duct occluders instead of conventional ventricular septal devices in the Department of Cardiology at Acharya Vinoba Bhave Rural Hospital (AVBRH) in central rural India. This study aimed to review success and complications and assess safety and its relation to age, sex, size of the VSDs, type of VSD, and types of devices used after transcatheter closure of perimembranous and muscular VSDs using various types of duct occluders. Methodology This retrospective study included patients who underwent percutaneous VSD device closure at the AVBRH between July 2017 and December 2020. We reviewed the patients' medical records to recognize imaging, clinical, and interventional data pre- and post-procedure and at the last follow-up. Results The success rate of VSD closure was 98.6%, one (0.7%) out of 81 females developed a complication due to device dislodgement, and one male aged six years (0.7%) out of 59 developed a post-procedural complication; hence, the total failure rate was 1.4%. The perimembranous type had no complication, and the muscular type had two (14.3%) unsuccessful procedures. Conclusion This study has concluded an impressive percentage of VSD closure, showing no mortality and low morbidity, using a percutaneous approach with different duct occluders. As the type of device used is not correlated with device failure and failure rate, duct occluders will be financially helpful in the closure of VSD in indicated patients.

Identifying developmental challenges of youth with congenital heart defects: A patient-oriented perspective

BACKGROUND

Youth with congenital heart disease (CHD) are at high risk for a range of developmental impairments that become evident at different times across childhood and adolescence. This study aimed to explore perspectives of youth with CHD with respect to their developmental follow-up across childhood.

METHODS

Interpretive description was used as a methodological approach for this qualitative study. Youth aged 12-22 years with CHD requiring open-heart surgery before 2 years of age and who had received health services in Canada since birth were enrolled.

RESULTS

Ten youth with CHD, two males and eight females, aged 13-22 years (mean 19.8) participated in this study. With higher social and academic demands as well as increased level of autonomy associated with older age, some youth faced new challenges that they had not encountered as children. Youth with CHD identified four aspects of the continuum of care as needing to be changed to better respond to their needs. First, the format of developmental follow-up needs to be adapted to their unique challenges. Second, resources must be more easily accessible throughout childhood and adolescence. Third, planning for transition to adult care is essential to ensure continuity of services. Finally, they identified that the school system is an essential component of the continuum of care.

CONCLUSIONS

Adolescents and young adults with CHD are at high risk of developing physical, academic and psychosocial challenges; however, timely identification of challenges does not appear to be optimal across domains and transition points, from the perspective of the youth themselves. Youth with CHD reported not having the resources and supports they required to optimize their functioning. Our findings suggest that several approaches could be adopted to enhance identification and outcomes to address the limitations of current Canadian practices.

Heart Disease and Stroke Statistics-2023 Update: A Report From the American Heart Association

BACKGROUND

The American Heart Association, in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, diet, and weight) and health factors (cholesterol, blood pressure, and glucose control) that contribute to cardiovascular health. The Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, congenital heart disease, rhythm disorders, subclinical atherosclerosis, coronary heart disease, heart failure, valvular disease, venous disease, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS

The American Heart Association, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing. The 2023 Statistical Update is the product of a full year's worth of effort in 2022 by dedicated volunteer clinicians and scientists, committed government professionals, and American Heart Association staff members. The American Heart Association strives to further understand and help heal health problems inflicted by structural racism, a public health crisis that can significantly damage physical and mental health and perpetuate disparities in access to health care, education, income, housing, and several other factors vital to healthy lives. This year's edition includes additional COVID-19 (coronavirus disease 2019) publications, as well as data on the monitoring and benefits of cardiovascular health in the population, with an enhanced focus on health equity across several key domains.

RESULTS

Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS

The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

The feasibility and safety of combining atrial septal defect/patent foramen ovale and left atrial appendage closure: A systematic review and meta-analysis

Introduction

Atrial Septal Defect/Patent Foramen Ovale (ASD/PFO) occlusion is performed to prevent paradoxical embolism and reduce the risk of recurrent ischemic stroke. Left atrial appendage (LAA) closure is used as an alternative to medical therapy of non-valvular atrial fibrillation for prevention of stroke. Multiple studies have examined performing LAA and ASD/PFO occlusion. However, the feasibility and safety of combined occlusion of the left atrial appendage and ASD/PFO are not clear, furthermore, these studies are limited by their small sample sizes and retrospective analysis. In this study, we aimed to systematically review and meta-analyze the feasibility and safety of combining left atrial appendage and ASD/PFO closure.

Methods

PubMed, Web of Science, CNKI, Cochrane Library, Embase, and WanFang database were searched up to April 2022 to identify peer-reviewed human studies on assessing the feasibility, safety, and efficacy of combining left atrial appendage and ASD/PFO closure. The primary outcome was calculated: procedural feasibility outcome and procedural safety outcome.

Results

A total of 10 articles, including 340 patients from multiple countries, were included in the analysis. The principal findings of our study are: compared with single LAA closure, (i) combining PFO/ASD occlusion and LAA closure had similar procedural success proportion (98.43%, 95% CI: 96.67-100.00%), (ii) similar safety event incidences developed (1.67%, 95% CI: 0.24-3.92%), subgroup analyzed safety event incidences in death was 0.00 (95% CI: 0.00-0.33%), cardiac tamponade was 0.87% (95% CI: 0.00-2.77%), device embolization was 0.00 (95% CI: 0.00-0.60%), major bleeding was 0.00 (95% CI: 0.00-0.33%), stroke was 0.00 (95% CI: 0.00-0.02%).

Conclusion

Although this systematic review and meta-analysis demonstrate the technical feasibility and safety of combining closure of PFO/ASD and LAA, further studies of sufficient sample size, long-term follow-up, and rigor endpoint criteria are yet needed to fully evaluate this combination procedure for its role in clinical outcomes.

Coronary Stent Placement in an Interarterial Anomalous Right Coronary Artery: An Alternative Approach in a Multimorbid High-risk Surgical Patient

Anomalous aortic origin of a coronary artery is a rare congenital anomaly and potential aetiology for sudden cardiac death. However, the mere presence of this anomaly does not portend clinical significance, and there are many factors that contribute to limiting coronary blood flow in these patients. The standard of care for symptomatic individuals is surgical management with coronary unroofing although not all cases are amenable to surgery. We report the case of an anomalous right coronary artery with interarterial course managed by percutaneous coronary intervention due to surgical contraindication secondary to comorbidities. The proposed mechanism of action culminating in aborted sudden cardiac death is unique and involves aggravated pulmonary hypertension in an individual with severe comorbid pulmonary disease.

Therapeutic Management of Anomalous Coronary Arteries Originating From the Opposite Sinus of Valsalva: Current Evidence, Proposed Approach, and the Unknowing

Anomalous coronary arteries originating from the opposite sinus of Valsalva (ACAOS) are a challenge because of their various anatomic and clinical presentation. Although the prevalence is low, the absolute numbers of detected ACAOS are increasing because of the growing use of noninvasive anatomical imaging for ruling out coronary artery disease. As evidence-based guidelines are lacking, treating physicians are left in uncertainty for the optimal management of such patients. The sole presence of ACAOS does not justify surgical correction, and therefore a thorough anatomic and hemodynamic assessment is warranted. Invasive and noninvasive multimodality imaging provides information to the clinical question whether the presence of ACAOS is an innocent coincidental finding, is responsible for the patient's symptoms, or even might be a risk for sudden cardiac death. Based on recent clinical data, focusing on the pathophysiology of patients with ACAOS, myocardial ischemia is dependent on both the extent of fixed and dynamic components, represented by anatomic high-risk features. These varying combinations should be considered individually in the decision making for the different therapeutic options. This state-of-the-art review focuses on the advantages and limitations of the common contemporary surgical, interventional, and medical therapy with regard to the anatomy and pathophysiology of ACAOS. Further, we propose a therapeutic management algorithm based on current evidence on multimodality invasive and noninvasive imaging findings and highlight remaining gaps of knowledge.

Total Thoracoscopic versus Robotic Surgery for Repair of Atrial Septum Defect: A Propensity Matching Score Analysis

Robotic surgery can provide less surgical trauma than conventional surgery, but differences between robotic and thoracoscopic surgery for atrial septal defect (ASD) repair are not well documented. To explore whether ASD can be repaired by thoracoscopic surgery or robotic surgery, which procedure is less invasive, and the difference in outcomes between these two procedures, this article studies 160 patients undergoing ASD repair at our institution. Sixty-five patients underwent total thoracoscopic surgery and 95 patients underwent total endoscopic robotic surgery. Propensity score matching yielded 64 well-matched patient pairs. Surgical data and early postoperative outcomes between the two matched groups were analyzed and compared. The results show that thoracoscopic and robotic surgery to repair ASD are both safe and reliable, and the early curative effect is good. However, regardless of similar complication rates, robotic surgery has a shorter time, less postoperative drainage, and faster recovery than thoracoscopic surgery.

Coronary Artery Origins Pattern in Pediatric Patients with Right-Left Fusion Bicuspid Aortic Valve

Bicuspid aortic valve (BAV) is a common congenital heart defect associated with coronary artery (CA) variants, including higher incidence of left CA dominance and shorter left main CA length. We observed by transthoracic echocardiography that left and right CA origins appear closer together in pediatric patients with right-left fusion (R/L) BAV compared to patients with trileaflet aortic valves. We sought to objectively confirm this observation. A retrospective review of pediatric echocardiograms with R/L BAV at a single institution (12/2010-11/2018) was performed. The 'coronary angle' was defined as the angle between the left and right coronary artery origins in the parasternal short axis view relative to the center of the aortic valve orifice. Values were compared to age-matched controls. Patients with inadequate images, anomalous coronary origins, or predefined significant congenital heart defects were excluded. We compared 191 R/L BAV patients (64% male) to 136 controls (57% male). Coronary angle was significantly more acute in R/L BAV than in controls (117.9° ± 16.7° vs 139.0° ± 10.1°, p < 0.0001). This was independent of age and gender. The difference persisted when BAV patients with abnormal aortic annulus/root diameters were removed from analysis (119.5° ± 15.1° vs 139.0° ± 10.1°, p < 0.0001). CA origins are closer together in R/L BAV independent of age, gender, or annulus/root size. This new anatomical description may aid in the diagnosis of subtle ('forme fruste') R/L BAV, assist in interventional planning, and improve understanding of the relationship between BAV and CA development.

Pre- and Postprocedure Imaging of Transcatheter Pulmonary Valve Implantation

Transcatheter pulmonary valve replacement (TPVR) is a minimally invasive procedure for treatment of right ventricular outflow tract (RVOT) dysfunction in surgically repaired congenital heart diseases. TPVR is performed in these patients to avoid the high risk and complexity of repeat surgeries. Several TPVR devices are now available to be placed in the right ventricle (RV) to pulmonary artery (PA) conduit, native RVOT, or surgical bioprosthetic valves. Imaging is used before TPVR to determine patient eligibility and optimal timing, which is critical to avoid irreversible RV dilatation and failure. Imaging is also required for evaluation of contraindications, particularly proximity of the RVOT to the left main coronary artery and its branches. Cross-sectional imaging provides details of the complex anatomy in which the TPVR device will be positioned and measurements of the RVOT, RV-PA conduit, or PA. Echocardiography is the first-line imaging modality for evaluation of the RVOT or conduit to determine the need for intervention, although its utility is limited by the complex RVOT morphology and altered anatomy after surgery. CT and MRI provide complementary information for TPVR, including patient eligibility, assessment of contraindications, and key measurements of the RVOT and PA, which are necessary for procedure planning. TPVR, performed using a cardiac catheterization procedure, includes a sizing step in which a balloon is expanded in the RVOT, which also allows assessment of the risk for extrinsic coronary artery compression. Follow-up imaging with CT and MRI is used for evaluation of postprocedure remodeling and valve function and to monitor complications. ^©RSNA, 2022 Online supplemental material is available for this article.

Liver parenchymal changes and association with cardiac magnetic resonance imaging findings in repaired tetralogy of Fallot: an intravoxel incoherent motion magnetic resonance imaging study

BACKGROUND

Liver disease can develop in repaired tetralogy of Fallot (TOF) from hepatic congestion caused by volume and pressure overload of the right ventricle. Noninvasive assessment of the liver is important for diagnosing and managing children with TOF.

OBJECTIVE

To evaluate subclinical hepatic changes without liver function test abnormality in adolescents with repaired TOF using intravoxel incoherent motion (IVIM) MRI and cardiac MRI findings.

MATERIALS AND METHODS

We included 106 young adults (75 with repaired TOF and 31 healthy individuals) in the study. Liver IVIM MRI examinations were performed with 10 b values (0, 10, 20, 30, 50, 80, 100, 200, 400, 800 s/mm²). Two observers measured IVIM MRI parameters D true, D* and f, as well as apparent diffusion coefficient (ADC) values in liver segments 5-8.

RESULTS

D* and f values were significantly lower in adolescents with TOF (P = 0.003 vs. P = 0.05, respectively). ADC values were higher in adolescents with TOF (P = 0.005). However, we found no significant difference between adolescents with and without TOF in terms of Dtrue (P = 0.53). There was a significant correlation between f value and right ventricular ejection fraction. The intraclass correlation coefficient (ICC) analysis of the two observers showed substantial-to-excellent agreement for D, f, D true and ADC (0.7, 0.8, 0.9 and 0.8, respectively).

CONCLUSION

The results of our study suggest that impaired microperfusion with increased ADC values in adolescents with repaired TOF reflect hepatic congestion rather than fibrosis. Hepatic congestion characterized by decreased ADC values can be easily differentiated before fibrotic changes occur by using IVIM MRI to assess diffusion and microcapillary perfusion separately.

Heart Failure and Patient-Reported Outcomes in Adults With Congenital Heart Disease from 15 Countries

Background

Heart failure (HF) is the leading cause of mortality and associated with significant morbidity in adults with congenital heart disease. We sought to assess the association between HF and patient‐report outcomes in adults with congenital heart disease.

Methods and Results

As part of the APPROACH‐IS (Assessment of Patterns of Patient‐Reported Outcomes in Adults with Congenital Heart disease—International Study), we collected data on HF status and patient‐reported outcomes in 3959 patients from 15 countries across 5 continents. Patient‐report outcomes were: perceived health status (12‐item Short Form Health Survey), quality of life (Linear Analogue Scale and Satisfaction with Life Scale), sense of coherence‐13, psychological distress (Hospital Anxiety and Depression Scale), and illness perception (Brief Illness Perception Questionnaire). In this sample, 137 (3.5%) had HF at the time of investigation, 298 (7.5%) had a history of HF, and 3524 (89.0%) had no current or past episode of HF. Patients with current or past HF were older and had a higher prevalence of complex congenital heart disease, arrhythmias, implantable cardioverter‐defibrillators, other clinical comorbidities, and mood disorders than those who never had HF. Patients with HF had worse physical functioning, mental functioning, quality of life, satisfaction with life, sense of coherence, depressive symptoms, and illness perception scores. Magnitudes of differences were large for physical functioning and illness perception and moderate for mental functioning, quality of life, and depressive symptoms.

Conclusions

HF in adults with congenital heart disease is associated with poorer patient‐reported outcomes, with large effect sizes for physical functioning and illness perception.

Subarachnoid haemorrhage in a patient with undiagnosed aortic coarctation

A man in his mid-30s was admitted with a thunderclap headache. He was conscious and hypertensive. A decade earlier, severe hypertension had been diagnosed and extensively investigated without revealing an underlying cause. Brain imaging showed subarachnoid haemorrhage caused by a ruptured pericallosal aneurysm. Endovascular occlusion was attempted, but as the sheath could not pass the aortic arch, it was converted to surgical aneurismal clipping. Intraoperative blood pressure measurement revealed a peak-to-peak gradient of 100 mm Hg across the aortic arch and an ankle/brachial index of 0.46 (normal range 0.9-1.2). Aortic coarctation was suspected, and angiographic imaging and echocardiography confirmed the diagnosis. Subacute direct stenting was performed, which normalised the peak-to-peak gradient and ankle/brachial index. To minimise the risk of severe complications, early diagnosis of aortic coarctation is important and can be facilitated by ankle/brachial index and echocardiography in the suprasternal view.

Clinical Outcome of Closure of a Small Atrial Septal Defect in a Patient with Pulmonary Arterial Hypertension

The closure of small/coincidental atrial septal defects (ASDs) in patients with pulmonary arterial hypertension (PAH) has been described in recent major guidelines as useless or even contraindicated. We confirm the effectiveness of "Treat and Repair" for ASD closure through one patient diagnosed with idiopathic PAH with small ASD, under careful observation with right heart catheterization and cardiac magnetic resonance imaging. The clinical decision concerning the closure of ASD with PAH should be made not only by referring to the guidelines but also by evaluating the benefits and risks specific to that case.

Long-standing hypoxaemia in complex adult congenital heart disease: anatomical and functional interplay in an uncommon presentation

We report a case of a 28-year-old man lost to follow-up with chronic hypoxaemia and a history of an uncorrected tricuspid hypoplasia, perimembranous ventricular septal defect (VSD) and pulmonary stenosis. Given this initial diagnosis, chronic hypoxaemia was deemed to result from right-to-left shunt through the VSD driven by elevated right ventricle pressures. However, the further investigation identified an inferior sinus venosus atrial septal defect, unveiling the true mechanism behind the clinical scenario. The patient was submitted to surgical correction with clinical improvement. This case illustrates the defiant evaluation of this type of atrial septal defect through echocardiography and underlines the importance of a multimodal evaluation to reach an accurate diagnosis and optimal management.

Aortic Coarctation Associated With Hypertrophic Cardiomyopathy in a Woman With Hypertension and Syncope: A Case Report With 8-Year Follow-Up

Background

Coarctation of the aorta (CoA) is a common congenital cardiovascular malformation with aortic narrowing in the region of the ligamentum arteriosum. Hypertrophic cardiomyopathy (HCM) is a primary cardiomyopathy that is characterized by left ventricular wall thickening and likely left ventricular outflow tract (LVOT) obstruction. They are two irrelevant diseases, and their coexistence has not been reported before. Here, we described a young female patient who concurrently has CoA and HCM.

Case Presentation

The patient has had hypertension since 18-years old and complained of chest discomfort on effort and fatigue thereafter. Initially, she was diagnosed as having hypertrophic cardiomyopathy and primary hypertension. The presence of CoA was not found until she was 35 years old when she had an onset of paroxysmal supraventricular tachycardia (PSVT) and presented with syncope. Failure of the ablation procedure via the femoral artery revealed the possibility of CoA and PDA that was confirmed by aortic CTA and angiography. CoA was then treated successfully with a covered stent, and the symptoms of the patient improved remarkably. Additionally, the patient had typical imaging features of HCM, and two novel HCM-causing heterozygous mutations were identified by genetic testing, DSP-encoding desmoplakin, and MYBPC3-encoding myosin-binding protein C. The HCM was suspected to be contributing to the clinical presentations of the patient and challenged the timely diagnosis of CoA. The 8-year follow-up on aortic CTA and angiography revealed no stent graft-related complications. Moreover, no changes in HCM-related imaging features were found in the follow-up echocardiography 8 years after the correction of aortic coarctation, which strengthened the diagnosis of HCM.

Conclusion

Here, we reported the diagnostic challenges, management, and 8-yeasr follow-up findings in a rare case of CoA combined with HCM. The case highlighted the importance for physicians to exclude CoA in young hypertensive patients, and proved the efficacy of stent repair in treating CoA in older patients.

Practical Therapeutic Management of Percutaneous Atrial Septal Defect Closure

Atrial septal defects (ASDs) are one of the most common congenital heart disorders encountered by cardiologists. Percutaneous ASD closure for secundum ASD is commonly performed not only for children but also for adults, given its non-inferiority to surgical repair. The choice of closure technique should be based on assessing a patient's baseline comorbidities, including the presence of pulmonary hypertension, supraventricular tachycardias, and left ventricular diastolic dysfunction. Furthermore, anatomical features and defect types determined using echocardiography need to be considered when developing a management plan. Percutaneous closure is often the preferred method, given its comparable successful rate to surgical repair while also being far less invasive.

Discontinuation of follow-up care for young people with complex chronic conditions: conceptual definitions and operational components

Background

A substantial proportion of young people with Complex Chronic Conditions (CCCs) experience some degree of discontinuation of follow-up care, which is an umbrella term to describe a broken chain of follow-up. Discontinuation of follow-up care is not clearly defined, and the great plethora of terms used within this field cannot go unnoticed. Terms such as “lost to follow-up”, “lapses in care” and “care gaps”, are frequently used in published literature, but differences between terms are unclear. Lack of uniformity greatly affects comparability of study findings. The aims of the present study were to (i) provide a systematic overview of terms and definitions used in literature describing discontinuation of follow-up care in young people with CCC’s; (ii) to clarify operational components of discontinuation of follow-up care (iii); to develop conceptual definitions and suggested terms to be used; and (iv) to perform an expert-based evaluation of terms and conceptual definitions.

Methods

A systematic literature search performed in PubMed was used to provide an overview of current terms used in literature. Using a modified summative content analysis, operational components were analysed, and conceptual definitions were developed. These conceptual definitions were assessed by an expert panel using a survey.

Results

In total, 47 terms and definitions were retrieved, and a core set of operational components was identified. Three main types of discontinuation of follow-up care emerged from the analysis and expert evaluation, conceptually defined as follows: Lost to follow-up care: “No visit within a defined time period and within a defined context, and the patient is currently no longer engaged in follow-up care”;Gap in follow-up care: “Exceeded time interval between clinic visits within a defined context, and the patient is currently engaged in follow-up care”; andUntraceability: “Failure to make contact due to lack of contact information”.

Conclusion

By creating a common vocabulary for discontinuation of follow-up care, the quality of future studies could improve. The conceptual definitions and operational components provide guidance to both researchers and healthcare professionals focusing on discontinuation of follow-up care for young people with CCCs.

Qualitative study of facilitators and barriers for continued follow-up care as perceived and experienced by young people with congenital heart disease in Sweden

In-depth understanding of factors perceived by young people with congenital heart disease (CHD) to affect continued follow-up care is needed to tailor preventive strategies for discontinuation of follow-up care. To identify facilitating factors, low-prevalence settings in terms of discontinuation should be investigated.

OBJECTIVE

This qualitative study describes factors affecting continued follow-up as perceived and experienced by young adults with CHD.

PARTICIPANTS

Using a mixed purposive sampling technique, 16 young adults with CHD were included. Three participants had discontinued follow-up care and 13 had continued follow-up care after transfer.

SETTING

Participants were recruited from all seven university hospitals in Sweden, which is considered a low-prevalence setting in terms of discontinuation.

DESIGN

Individual interviews were performed and subjected to qualitative content analysis.

RESULTS

The analysis resulted in three main categories, illuminating factors affecting continued follow-up: (1) motivation for follow-up care; (2) participation in care and sense of connectedness with healthcare provider (HCP) and (3) care accessibility. The choice of continuing follow-up or not was multifactorial. Knowledge of your CHD and the importance of continuing follow-up care was a central factor, as well as experiencing CHD-related symptoms and having ongoing or planned medical treatment or interventions. Sensing a clear purpose with follow-up care was facilitating, as was feeling well treated and cared for by HCPs. Practical aspects, such as travel distance was also stressed, as well as active invitations and reminders for visits.

CONCLUSION

Factors on both patient, hospital and healthcare system level were raised by participants, stressing the importance of holistic approaches when developing preventive strategies for discontinuation. There is a need for improved skills and competencies among HCPs, as well as a person-centred approach to follow-up care. In addition, specific healthcare needs and remaining transitional needs after transfer to adult care require careful consideration to prevent discontinuation.

Heart transplantation in adults with congenital heart disease: a 17-year single center experience

BACKGROUND

Heart transplantation (HTx) in adults with congenital heart disease (ACHD) remains challenging because of structural anomalies and often previous procedure. The aim of this retrospective study was to describe the outcomes of heart transplantation (HTx) in a cohort of ACHD patients at our tertiary centre.

PATIENTS AND METHODS

Between January 1993 and December 2010, 223 consecutive adult patients (age > 18 years) underwent HTx at our institution. Fifteen (6.7%) were ACHD patients. Outcomes were reviewed using our institution's HTx database. We looked at 30-day, 1, 5 and 10-years survival, as well as post-transplantation complications.

RESULTS

The mean age at HTx of the groups of ACHD was 42 ± 14.4 years, vs 54.2 ± 9.8 years for the non-CHD patients. Prior to transplant, thirteen of the fifteen ACHD had undergone one or more surgical procedures including palliative or corrective open-heart procedures in 66.6% of them. Seven of the fifteen ACHD (47%) required additional surgical procedures at transplantation. The mean follow-up was 95,44 ± 84.3 months. There was no significant difference in survival (ACHD vs non-CHD) at 30 days (87% vs. 90%), 1 year (73% vs. 74.5%) or 5 years (53% vs. 55%). Survival at 10 years was respectively 53% and 41% for ACHD patients and non-CHD patients.

CONCLUSION

Despite the surgical challenge, HTx in ACHD has a good long-term result. However, the small sample size of our cohort limits any definitive conclusions.

What was the impact of the first wave of COVID-19 on the delivery of care to children and adults with congenital heart disease? A qualitative study using online forums

OBJECTIVES

Globally, healthcare systems have been stretched to the limit by the COVID-19 pandemic. Significant changes have had to be made to the way in which non-COVID-19-related care has been delivered. Our objective was to understand, from the perspective of patients with a chronic, life-long condition (congenital heart disease, CHD) and their parents/carers, the impact of COVID-19 on the delivery of care, how changes were communicated and whether healthcare providers should do anything differently in a subsequent wave of COVID-19 infections.

DESIGN AND SETTING

Qualitative study involving a series of asynchronous discussion forums set up and moderated by three patient charities via their Facebook pages.

PARTICIPANTS

Patients with CHD and parents/carers of patients with CHD.

MAIN OUTCOME MEASURES

Qualitative responses to questions posted on the discussion forums.

RESULTS

The forums ran over a 6-week period and involved 109 participants. Following thematic analysis, we identified three themes and 10 subthemes related to individual condition-related factors, patient-related factors and health professional/centre factors that may have influenced how patients and parents/carers experienced changes to service delivery as a result of COVID-19. Specifically, respondents reported high levels of disruption to the delivery of care, inconsistent advice and messaging and variable communication from health professionals, with examples of both excellent and very poor experiences of care reported. Uncertainty about follow-up and factors related to the complexity and stability of their condition contributed to anxiety and stress.

CONCLUSIONS

The importance of clear, consistent communication cannot be over-estimated. Our findings, while collected in relation to patients with CHD, are not necessarily specific to this population and we believe that they reflect the experiences of many thousands of people with life-long conditions in the UK. Recommendations related to communication, service delivery and support during the pandemic may improve patients' experience of care and, potentially, their outcomes.

Associations Between Clinical Outcomes and a Recently Proposed Adult Congenital Heart Disease Anatomic and Physiological Classification System

Background

American Heart Association and American College of Cardiology consensus guidelines introduce an adult congenital heart disease anatomic and physiological (AP) classification system. We assessed the association between AP classification and clinical outcomes.

Methods and Results

Data were collected for 1000 outpatients with ACHD prospectively enrolled between 2012 and 2019. AP classification was assigned based on consensus definitions. Primary outcomes were (1) all‐cause mortality and (2) a composite of all‐cause mortality or nonelective cardiovascular hospitalization. Cox regression models were developed for AP classification, each component variable, and additional clinical models. Discrimination was assessed using the Harrell C statistic. Over a median follow‐up of 2.5 years (1.4–3.9 years), the composite outcome occurred in 185 participants, including 49 deaths. Moderately or severely complex anatomic class (class II/III) and severe physiological stage (stage D) had increased risk of the composite outcome (AP class IID and IIID hazard ratio, 4.46 and 3.73, respectively, versus IIC). AP classification discriminated moderately between patients who did and did not suffer the composite outcome (C statistic, 0.69 [95% CI, 0.67–0.71]), similar to New York Heart Association functional class and NT‐proBNP (N‐terminal pro‐B‐type natriuretic peptide); it was more strongly associated with mortality (C statistic, 0.81 [95% CI, 0.78–0.84]), as were NT‐proBNP and functional class. A model with AP class and NT‐proBNP provided the strongest discrimination for the composite outcome (C statistic, 0.73 [95% CI, 0.71–0.75]) and mortality (C statistic, 0.85 [95% CI, 0.82–0.88]).

Conclusions

The addition of physiological stage modestly improves the discriminative ability of a purely anatomic classification, but simpler approaches offer equivalent prognostic information. The AP system may be improved by addition of key variables, such as circulating biomarkers, and by avoiding categorization of continuous variables.

Outcomes of women with congenital heart disease admitted to acute-care hospitals for delivery in Japan: a retrospective cohort study using nationwide Japanese diagnosis procedure combination database

Background

The number of women with congenital heart disease (CHD) who are of childbearing age is increasing due to advancements in medical management. Nonetheless, data on the outcomes of delivery in women with CHD remain limited. Therefore, we conducted a retrospective cohort study using a nationwide database of deliveries by women with CHD.

Methods

Deliveries by women with CHD discharged from acute-care hospitals between April 2017 and March 2018 were identified based on the Diagnosis Procedure Combination database which covers almost all acute-care hospitals in Japan. By using this database, we tried to include relatively high-risk deliveries by women with CHD. Subjects were divided into three groups according to the underlying disease complexity: simple, moderate, and great complexity. The clinical characteristics and incidence of peripartum cardiovascular events were compared among the three groups.

Results

A total of 249 deliveries from 107 hospitals were included. The largest facility had 29 deliveries per year. Given the uncertainty of underlying cardiac anomalies, 48 women were excluded, and the remaining 201 women (median age, 32 years) were analyzed. In-hospital maternal death, use of extracorporeal membrane oxygenation, intra-aortic balloon pump, pacemaker, and direct current cardioversion were not observed. Nine patients (4.5%) required intravenous diuretic administration. However, the difference in the frequency of diuretic use was not significant among the three groups (simple, 1.9%; moderate, 7.2%; great, 6.9%; P = 0.204). One participant required valve replacement surgery at 22 days after a successful cesarean section. As the disease complexity increased, deliveries occurred more frequently at university hospitals (simple, 41.7%; moderate, 52.2%; great, 72.4%; P = 0.013) and the length of hospitalization was significantly longer, with median durations of 9.0 (interquartile range [IQR] 7.0–11.0) days, 10.0 (IQR 8.0–24.0) days, and 11.0 (IQR 8.0–36.0) days in the simple, moderate, and great complexity groups, respectively (P = 0.002).

Conclusions

Appropriate patient selection and management by specialized tertiary institutions may contribute to positive outcomes in pregnancies in women with CHD.

Comparison of Del Nido and Blood Cardioplegia in Pediatric Patients Undergoing Surgical Repair for Congenital Heart Disease

The aim of the study is to investigate the impact of two different cardioplegia solutions, the del Nido (dN) and blood cardioplegia (BC), on postoperative troponin concentrations, vasoactive-inotrope score, and length of hospital stay in pediatric patients undergoing cardiovascular surgery for CHD. 80 subjects aged between 1 and 120 months who were scheduled for surgical repair for a CHD were prospectively enrolled in this study. Study subjects were allocated to one of the study groups using simple randomization technique as follows: The del Nido cardioplegia group (n = 40, median age 8.5 [5.5-14] months) and conventional blood cardioplegia group (n = 40, median age 11 [5-36] months). Aortic cross-clamp time and cardiopulmonary bypass time were recorded in all subjects. Troponin I and vasoactive-inotropic score, which indicates the amount of cardiovascular support by various inotropes or vasopressors, were recorded following the repair. The difference in troponin I, vasoactive-inotropic score (VIS), length of ICU stay, and length of hospital stay between the two groups was the primary outcome measure of this study. The volume of cardioplegia was significantly lower in dN group than that of the BC group (p < 0.001). Cardiopulmonary bypass time and aortic cross-clamp time were significantly shorter in subjects receiving dN cardioplegia than those receiving BC (p = 0.006, and p = 0.001, respectively). Subjects assigned to BC had higher Troponin I concentrations at postoperative 24th hour compared to subjects receiving dN cardioplegia [1.60 (0.92-2.49) ng/mL vs. 1.03 (0.55-1.83) ng/mL, p = 0.045]. VIS was also significantly higher in BC group at 24th [10 (10-13) vs. 10 (5-10), p = 0.032] and 48th hours [10 (1.5-10) vs. 0 (0-10), p = 0.005] compared to that of the dN cardioplegia group. The median extubation time was 7.5 (3.5-20.5) hours in dN cardioplegia group and 5 (4-10) hours in the BC group (p = 0.384). There were no significant differences between the groups with respect to the length of ICU stay and length of hospital stay. No mortality and no significant arrhythmias requiring medical or electrical cardioversion were noted in any of the groups. In conclusion, dN cardioplegia provides shorter aortic cross-clamp time and cardiopulmonary bypass time, and lower postoperative troponin I concentration and vasoactive-inotrope scores compared to BC in pediatric subjects undergoing surgical repair for CHD. However, lengths of ICU and hospital stay are similar in dN cardioplegia and BC groups.

A case report of hepatocellular carcinoma derived from Rastelli procedure-related congestive liver disease

The prognosis of congenital heart disease in children has improved, but late complications in adulthood are becoming an important problem. One late complication after congenital heart surgery is congestive liver disease, leading to liver cirrhosis and hepatocellular carcinoma (HCC). The Rastelli procedure is one of the surgical methods for transposition of the great arteries. We present the first case of HCC derived from Rastelli procedure-related congestive liver disease in a 41-year-old male. The patient underwent the Rastelli operation at 2 years of age and right ventricular outflow tract reconstruction at 10 and 35 years of age due to right ventricular outflow tract obstruction. At 41 years of age, a hepatic tumor was detected by computed tomography. Abdominal enhancing computed tomography revealed a partially hypervascular tumor in segment 2 in early phase and wash-out in late phase. The patient was diagnosed with HCC and underwent left lateral segmentectomy of the liver, splenectomy, and partial gastrectomy. The patient was discharged on the 28th postoperative day without postoperative complications. In the management of patients after the Rastelli operation, surveillance for congestive liver disease and HCC development is important, even if the patients have undergone right ventricular outflow tract reconstruction.

A valuable echocardiographic indicator for the optimal tightness of bilateral pulmonary artery banding

OBJECTIVES

The optimal tightness of bilateral pulmonary artery banding (BPAB) is considered to balance not only systemic-to-pulmonary blood flow but also each pulmonary blood flow, which is still challenging. To achieve them, we adopt the end-diastolic velocity (EDV) to the peak systolic velocity (PSV) ratio at BPAB with intraoperative epicardial echocardiography. We evaluated the usefulness of the EDV to PSV ratio and the patient outcomes.

METHODS

34 patients underwent BPAB with this indicator and using a looped polytetrafluoroethylene suture. The PSV and the EDV to PSV ratio with echocardiography were measured in the intraoperative, early postoperative and late postoperative period. Lung perfusion scintigraphy was performed to quantify flow to each lung.

RESULTS

There were 3 early deaths (< 30 days). Two patients required re-BPAB due to hypoxia. The intraoperative EDV to PSV ratios in the right and left were almost equal (0.50 ± 0.07 versus 0.51 ± 0.06, P = 0.73). There was no significant difference in the right and left EDV to PSV ratios throughout the postoperative course. The right PSV was smaller than the left PSV due to the Doppler angle intraoperatively (2.78 ± 0.57 versus 3.02 ± 0.50, P = 0.030). In addition, the PSV changed significantly until the late postoperative period (P < 0.001). Lung perfusion scintigraphy revealed only two patients had perfusion abnormalities.

CONCLUSIONS

Our clinical outcomes are satisfactory with low early mortality and a low rate of re-BPAB. The EDV to PSV ratio can be a reliable indicator to assess flow distribution to each lung and may be a valuable adjunct to achieve balanced systemic to pulmonary flow.

Cardiac computed tomography angiography in the pre-operative assessment of congenital heart disease in Thailand

Introduction

Cardiac computed tomography angiography (CCTA) plays a vital role in clinical practice in evaluating patients with congenital heart disease (CHD) when the information from echocardiography is equivocal.

Aim

To test the hypothesis that CCTA has significantly value for pre-operative evaluation of congenital heart disease and practicality in the diagnosis and management of congenital heart disease patients at our tertiary care academic hospital.

Material and methods

We studied a total of 78 congenital heart disease patients (median age: 4.5 years) who had undergone CCTA during the period January 2017 to October 2018 at our tertiary care academic hospital.

Results

The results were classified as diagnostic categories, and the impact of the procedure on strategizing management was analysed. In each group, the CCTA offered an advantage and provided specific clues for surgical or interventional management. In total, the sensitivity (97.5%), specificity (100%), positive predictive value (100%), negative predictive value (99.38%), and accuracy (99.5%) of CCTA, for which the significant findings were confirmed by surgical or cardiac catheterization, were excellent, with average exposure per CCTA study calculated at 1.41 (0.36–3.28) mSv.

Conclusions

CCTA is an excellent non-invasive modality for the evaluation of congenital heart disease patients, with an important diagnostic and decision-aiding role.

Genesis of a coronary-cameral fistula

Coronary artery fistulae are a rare congenital abnormality. If such fistulae drain directly into a cardiac chamber, they are termed coronary-cameral fistulae. Such fistulae are usually congenital in origin or, occasionally, may arise as an iatrogenic complication of a cardiac procedure such as cardiac catheterization or surgery. We present a highly unusual case in which a patient presented to cardiac services on two occasions-nearly a decade apart-and was found to have coronary aneurysms initially, the largest of which expanded further and into the right atrium, thus creating a coronary-cameral fistula.

Valvular heart disease in congenital heart disease: a narrative review

Patients with congenital heart disease (CHD) are one of the fastest growing populations in cardiology, and valvular pathology is at the center of many congenital lesions. Derangements in valvular embryology lead to several anomalies prone to dysfunction, each with hemodynamic effects that require appropriate surveillance and management. Surgical innovation has provided new treatments that have improved survival in this population, though has also contributed to esotericism in patients who already have unique anatomic and physiologic considerations. Conduit and prosthesis durability are often monitored collaboratively with general and specialized congenital-focused cardiologists. As such, general cardiologists must become familiar with valvular disease with CHD for appropriate care and referral practices. In this review, we summarize the embryology of the semilunar and atrioventricular (AV) valves as a foundation for understanding the origins of valvular CHD and describe the mechanisms that account for heterogeneity in disease. We then highlight the categories of pathology from the simple (e.g., bicuspid aortic valve, isolated pulmonic stenosis) to the more complex (e.g., Ebstein's anomaly, AV valvular disease in single ventricle circulations) with details on natural history, diagnosis, and contemporary therapeutic approaches. Care for CHD patients requires collaborative effort between providers, both CHD-specialized and not, to achieve optimal patient outcomes.

Anomalous coronary artery origin from the opposite sinus in patients with bicuspid aortic valve: comparison with tricuspid aortic valve

Objective

To compare the prevalence and patterns of anomalous coronary artery origin from the opposite sinus (ACAOS) in patients with bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV).

Methods

Retrospective review of consecutive patients with surgically excised BAV and TAV was performed from 1994 to 2015. Clinical notes, echocardiograms, coronary angiograms, CT angiographies, and pathology reports were reviewed. ACAOS included right coronary artery from the left cusp, left circumflex artery from the right cusp and left main or left anterior descending artery from the right cusp.

Results

2371 (years 1994–2015) and 1679 (years 2009–2015) consecutive patients with pathology-confirmed BAV and TAV, respectively, and defined preoperative coronary anatomy were identified. A left dominant coronary circulation was present in 386 (18%) patients with BAV and 179 (11%) patients with TAV (p<0.001). ACAOS was identified in 43 (1.8%) patients with BAV and 15 (0.9%) patients with TAV, p=0.02. Among patients with BAV and ACAOS, the most common phenotype was right-left fusion (n=34, 79%) with present raphe (n=36, 84%), with no association between BAV phenotype and ACAOS type. On multivariate analysis, BAV status and size of the mid-ascending aorta were independently associated with ACAOS (OR 3.29; CI 1.26 to 8.6; p=0.02; OR 0.93; CI 0.87 to 0.98; p=0.01; respectively). Only two patients with ACAOS, one with BAV and one with TAV, had a perioperative coronary ischaemic event.

Conclusions

The prevalence of the potentially malignant ACAOS is significantly higher (threefold higher odds) in patients with BAV as compared with TAV, yet remains uncommon in absolute terms. Most patients with BAV and ACAOS had right-left cusp fusion and present raphe. Perioperative coronary events are rare in patients with ACAOS.

Midterm follow up of transcatheter closure of coronary artery fistula with Nit-Occlud® patent ductus arteriosus coil

BACKGROUND

Coronary artery fistula (CAF) is a rare congenital anomaly with a challenging scenario in children. This study reports our experience in transcatheter closure of CAF with Nit-Occlude PDA coil and midterm clinical and imaging follow-up.

METHODS

Twelve children with congenital CAF between 2009 and 2019, mean age 2.05 ± 2.05 years (4 days to 7.2 years), mean weight 8.8 ± 4.83 (2.8-17 kg), who underwent transcatheter closure with PFM coil at the Namazi hospital, Shiraz, Iran, were reported. Echocardiography and electrocardiogram were done before and after the procedure (early, 3, and 6 months after), and Multi-slice computerized tomography or conventional coronary angiography was performed at least one year after closure.

RESULTS

In a median follow-up of 5.5 years (range 13 months to 8 years), retrogradely closed fistula had no residual, and the fistula tract was wholly occluded, but in most anterogradely closed fistula, had a small residual, which made the fistula tract open and need additional coil closure.

CONCLUSIONS

Transcatheter closure of CAF with PFM coil is feasible and effective with low mortality and morbidity, although antegrade closure with this device may be accompanied by residual shunt and need for multiple coil insertion.

Heart failure in adults with congenital heart disease: a narrative review

The number of adults with congenital heart disease (ACHD) has increased over the last decades due to advancements in medical care, including interventional and surgical therapies. We are therefore more frequently challenged by the long-term consequences of palliative or corrective surgery carried out during childhood. Although patients with ACHD may develop conditions related to general cardiovascular risk factors, such as coronary artery disease, the most common complications leading to morbidity and mortality are arrhythmias, heart failure and thromboembolic events. For the management of arrhythmias, current recommendations regarding ablation and device therapy must be considered, whilst also taking into account the anatomical limitations of their congenital heart defect or surgical pathways. Heart failure treatment in acute and chronic settings must also consider the particular anatomy present, including the nature of the systemic ventricle. Treatments strategies for ACHD are typically extrapolated from the respective guidelines in non-ACHD patients, despite a lack of evidence to support this strategy. Right heart failure can be especially challenging to manage in conditions where either a systemic right ventricle or shunt lesions resulting in volume and/or pressure loading of the right ventricle are present. All physicians and cardiologists in particular should be acquainted with the most common diseases in ACHD, their complications and management regime, especially with regards to heart failure as this is a common reason for acute presentation in the emergency department.

4D Flow MRI Quantification of Congenital Shunts: Comparison to Invasive Catheterization

PURPOSE

To compare invasive right heart catheterization with four-dimensional (4D) flow MRI for estimating shunt fraction in patients with intracardiac and extracardiac shunts.

MATERIALS AND METHODS

In this retrospective study, patients who underwent 4D flow MRI and invasive right heart catheterization with a shunt run between August 2015 and November 2018 were included. The primary objective was comparison of estimated shunt fraction (ratio of pulmonary-to-systemic flow, Q_p/Q_s) at 4D flow and catheterization. Secondary objectives included comparison of the right ventricular-to-left ventricular stroke volume ratio (RVSV/LVSV) to shunt fraction (for those with applicable shunts) and comparison of cardiac output between 4D flow and catheterization. Statistical analysis included Pearson correlation and Bland-Altman plots.

RESULTS

A total of 33 patients met inclusion criteria (mean age, 49 years ± 16 [standard deviation]; 24 women). 4D flow measurements of Q_p/Q_s strongly correlated with those at catheterization (r = 0.938), and there was no bias. RVSV/LVSV correlated strongly with Q_p/Q_s from 4D flow (r = 0.852) and catheterization (r = 0.842). Measurements of left ventricle (Q_s) and right ventricle (Q_P) cardiac output from 4D flow and catheterization (Fick) correlated moderately overall (r = 0.673 [Q_p] and r = 0.750 [Q_s]).

CONCLUSION

Shunt fraction measurement using 4D flow MRI compares well with that using invasive cardiac catheterization.Supplemental material is available for this article.© RSNA, 2021.

Staged Endovascular Repair of Aortic Coarctation followed by Double Valve Surgery

We present a unique case of late diagnosis of coarctation of the aorta in an adult, presenting with congestive heart failure associated with severe aortic and mitral valve insufficiency. To minimize operative risk, staged endovascular repair of the coarctation was initially performed, followed by aortic valve replacement and mitral valve repair. Six months postoperatively, the 41-year-old patient remains completely asymptomatic.

Heart Disease and Stroke Statistics-2021 Update: A Report From the American Heart Association

BACKGROUND

The American Heart Association, in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, diet, and weight) and health factors (cholesterol, blood pressure, and glucose control) that contribute to cardiovascular health. The Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, congenital heart disease, rhythm disorders, subclinical atherosclerosis, coronary heart disease, heart failure, valvular disease, venous disease, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS

The American Heart Association, through its Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States to provide the most current information available in the annual Statistical Update. The 2021 Statistical Update is the product of a full year's worth of effort by dedicated volunteer clinicians and scientists, committed government professionals, and American Heart Association staff members. This year's edition includes data on the monitoring and benefits of cardiovascular health in the population, an enhanced focus on social determinants of health, adverse pregnancy outcomes, vascular contributions to brain health, the global burden of cardiovascular disease, and further evidence-based approaches to changing behaviors related to cardiovascular disease.

RESULTS

Each of the 27 chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS

The Statistical Update represents a critical resource for the lay public, policy makers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Efficacy of catheter ablation for patients with atrial fibrillation and atrial septal defect

INTRODUCTION

Given that few studies investigated the efficacy of catheter ablation (CA) in patients with paroxysmal atrial fibrillation (AF) and atrial septal defect (ASD), this study evaluated its effectiveness in patients with paroxysmal AF and ASD.

METHODS AND RESULTS

Of the 216 patients who underwent ASD device closure at two hospitals, 36 patients had paroxysmal AF. After April 2012, CA for AF was performed before ASD device closure (ASD-CA group; n = 20). The ASD-CA group had a significantly higher AF-free survival rate after ASD device closure compared to patients without CA for AF before ASD device closure (ASD-non-CA group; n = 16) (ASD-CA group: 2 patients vs. ASD-non-CA group: 9 patients; follow-up period: 4.2 ± 2.5 years; log-rank p = .01). In addition, the AF-free survival rates were similar between the ASD-CA group and 80 paroxysmal AF patients who underwent CA without any detectable structural heart disease (non-SHD-CA group). The two groups were matched by propensity scores for age, sex, and left atrium dimension (ASD-CA group: 2 patients vs. non-SHD-CA group: 5 patients; follow-up period: 3.3 ± 1.8 years; log-rank p = .28).

CONCLUSION

CA for AF before ASD device closure might be an effective treatment option for patients with paroxysmal AF and ASD.

Percutaneous Closure of Ventricular Septal Defects in 116 Patients: Experience with different devices

Objectives

This study aimed to review the experience with percutaneous closure of ventricular septal defects (VSDs) at the National Heart Center (NHC) in Muscat, Oman.

Methods

This retrospective study was conducted from November 2008 to December 2017. Patients’ electronic medical records were reviewed to identify their clinical, imaging and interventional data before and after the procedure and on the last follow-up.

Results

A total of 116 patients, the majority of which were female (58%), underwent 118 percutaneous procedures for VSD closure at a median age of 3.54 years (range: 0.25–33 years) and a median weight of 12 kg (range: 3.5–78 kg). The mean diameter of the VSDs as determined by transoesophageal echocardiogram was 5.6 ± 1.9 mm (n = 105). The commonest type of VSD was perimembranous (n = 75, 63.5%). Devices were successfully placed during 111 (94.1%) procedures in 109 (94.0%) patients, with the commonest device being a Amplatzer™ duct occluder I (St. Jude Medical, Little Canada, Minnesota, USA; n = 39, 35.1%). There was no mortality. Early major cardiac complications occurred in six patients (5.5%) with device embolisation being the commonest (n = 4, 3.7%). The median follow-up period was 19 months (range: 1–84 months) in 89 (81.7%) of the patients. One patient (0.9%) required a permanent pacemaker for a complete heart block.

Conclusion

This study has demonstrated a good rate of VSD closure with low morbidity and no mortality using the percutaneous approach with different devices. Long-term follow-up is needed to specifically evaluate the function of adjacent structures and the long-term effects on conduction systems.

Preoperative Hemoglobin Level, Oxygen Saturation and Postoperative Outcomes in Children With Cyanotic Congenital Heart Disease: A Propensity-Score Matching Analysis

BACKGROUND

The optimal preoperative hemoglobin (Hb) level is difficult to define in children with cyanotic congenital heart disease (CHD) due to hypoxemia-induced secondary erythrocytosis. This retrospective study integrated preoperative Hb and pulse oxygen saturation (SpO₂) using the product of Hb × SpO₂ to predict postoperative outcomes in children with cyanotic CHD.

PATIENTS AND METHODS

Children aged <18 years undergoing cardiac surgery with cyanotic CHD were included. The cutoff value of Hb × SpO₂ was the age-adjusted lower limit of normal Hb (aaHb) in healthy children. The main outcomes were in-hospital death and the composite outcome of severe postoperative events. Multivariate logistic regression analysis and propensity score matching analysis were used to adjust for important confounders.

RESULTS

The presence of preoperative Hb × SpO₂ < aaHb was observed in 21.6% of cyanotic children (n = 777). Children with Hb × SpO₂ < aaHb had higher in-hospital mortality (12.5% vs. 4.6%, P < 0.001) and composite outcome incidence (69.6% vs. 32.3%, P < 0.001) than those with Hb × SpO₂ ≥ aaHb. After propensity score matching, 141 pairs of children were successfully matched. Multivariate analysis showed that preoperative Hb × SpO₂ < aaHb was significantly associated with the composite outcome in the entire population (odds ratio = 4.092, 95% confidence interval = 2.748-6.095, P < 0.001) and the matched cohorts (odds ratio = 2.277, 95% confidence interval = 1.366-3.795, P = 0.002).

CONCLUSION

Our results suggest that a preoperative Hb × SpO₂ value below the lower limit of normal hemoglobin is a prognostic factor in cyanotic children undergoing cardiac surgery and is a potential criterion to evaluate preoperative anemia in this population.
