Assessing the feasibility of using the antecubital vein to perform right heart catheterization in children and adults with congenital heart disease: a retrospective, observational single-center study

BACKGROUND

Right heart catheterization (RHC) usually is performed via the femoral vein or the internal jugular vein. However, the antecubital fossa vein is a valid venous access, and it has become increasingly popular to perform right heart catheterization utilizing this access.

METHODS

A retrospective, observational study was conducted to describe use of the antecubital fossa vein for right heart catheterization in adults and children with congenital heart disease (CHD). Patients who had undergone RHC via antecubital fossa vein at the authors' hospital between September 2019 and December 2022 were included. The outcomes studied were procedural failure and procedure-related adverse events.

RESULTS

Fifty-two patients with CHD underwent right cardiac catheterization via an upper arm vein. The upper arm vein was unable to perform the RHC in only 2 patients (3.8%). Only 1 patient developed a minor adverse event. No irreversible and/or life-threating adverse events were detected.

CONCLUSIONS

The upper arm veins are safe and effective to perform a RHC in children and adults with CHD. This approach demonstrates a high percentage of technical success, and few mild complications.

Pregnancy in Patients with Moderate and Highly Complex Congenital Heart Disease

Although not completely devoid of risk, pregnancy can be managed in virtually all patients affected by even the most complex forms of congenital heart disease. It is not however advisable in patients with any form of pulmonary arterial hypertension. Pregnancy is even manageable in patients with univentricular heart converted to Fontan circulation. A personalised risk stratification should be performed, and patients affected by advanced NYHA functional class appropriately warned of the potential risks. In this setting, metabolomics might represent a novel tool for use in conducting personalised risk stratification. All pregnancies, particularly those at higher risk, should be managed in a tertiary care centre capable of providing the necessary assistance to both the mother and infant. With a few rare exceptions, vaginal delivery is to be preferred over caesarean section due to the lower degree of maternal and foetal complications. The desire for motherhood, at times extreme in women with congenital heart disease, may often be accomplished, thus providing a ray of hope in the lives of these patients.

Perioperative Management of an Adolescent Fontan Patient with Narrowing of the Aortopulmonary Space for Posterior Scoliosis Surgery

Congenital cardiac patients who received neonatal reconstructive aortic arch surgery are at risk of aortopulmonary space narrowing with compression of the left pulmonary artery and left main bronchus (LMB) later in life. We discuss a challenging adolescent single ventricle patient who presented for surgical treatment of a non-idiopathic thoracic scoliosis (posterior spinal fusion) with severe stenosis of the LMB and left pulmonary artery due to a narrow aortopulmonary space. Careful preoperative imaging, evaluation, and decision making resulted in successful surgical treatment and uneventful perioperative course.

High prevalence of ascending aortic dilation in adults with repaired coarctation of the aorta

BACKGROUND

Ascending aortic dilation is a feared complication in adults with repaired coarctation of the aorta, as the condition is associated with life-threatening complications such as aortic dissection and rupture. However, the data are currently limited regarding factors associated with ascending aortic dilation in these patients.

METHODS AND RESULTS

From the national register of congenital heart disease, 165 adult patients (≥ 18 years old) with repaired coarctation of the aorta, and echocardiographic data on aortic dimensions, were identified (61.2% male, mean age 35.8 ± 14.5 years). Aortic dilation (aortic diameters > 2 SD above reference mean) was found in 55 (33.3%) of the 165 included patients, and was associated with manifest aortic valve disease in univariable logistic regression analysis (OR 2.44, 95% CI [1.23, 4.83]).

CONCLUSIONS

Aortic dilation is common post-repair of coarctation of the aorta, and is associated with manifest aortic valve disease and thus indirectly with the presence of a bicuspid aortic valve. However, no association was found between aortic dilation and age or blood pressure.

Imaging the adult with simple shunt lesions: position paper from the EACVI and the ESC WG on ACHD. Endorsed by AEPC (Association for European Paediatric and Congenital Cardiology)

In 2018, the position paper 'Imaging the adult with congenital heart disease: a multimodality imaging approach' was published. The paper highlights, in the first part, the different imaging modalities applied in adult congenital heart disease patients. In the second part, these modalities are discussed more detailed for moderate to complex anatomical defects. Because of the length of the paper, simple lesions were not touched on. However, imaging modalities to use for simple shunt lesions are still poorly known. One is looking for structured recommendations on which they can rely when dealing with an (undiscovered) shunt lesion. This information is lacking for the initial diagnostic process, during repair and at follow-up. Therefore, this paper will focus on atrial septal defect, ventricular septal defect, and persistent arterial duct. Pre-, intra-, and post-procedural imaging techniques will be systematically discussed. This position paper will offer algorithms that might help at a glance. The document is prepared for general cardiologists, trainees, medical students, imagers/technicians to select the most appropriate imaging modality and to detect the requested information for each specific lesion. It might serve as reference to which researchers could refer when setting up a (imaging) study.

Right Ventricular Volume and Function Assessment in Congenital Heart Disease Using CMR Compressed-Sensing Real-Time Cine Imaging

Background and objective: To evaluate the reliability of compressed-sensing (CS) real-time single-breath-hold cine imaging for quantification of right ventricular (RV) function and volumes in congenital heart disease (CHD) patients in comparison with the standard multi-breath-hold technique. Methods: Sixty-one consecutive CHD patients (mean age = 22.2 ± 9.0 (SD) years) were prospectively evaluated during either the initial work-up or after repair. For each patient, two series of cine images were acquired: first, the reference segmented multi-breath-hold steady-state free-precession sequence (SSFP_ref), including a short-axis stack, one four-chamber slice, and one long-axis slice; then, an additional real-time compressed-sensing single-breath-hold sequence (CS_rt) providing the same slices. Two radiologists independently assessed the image quality and RV volumes for both techniques, which were compared using the Wilcoxon test and paired Student’s t test, Bland–Altman, and linear regression analyses. The visualization of wall-motion disorders and tricuspid-regurgitation-related signal voids were also analyzed. Results: The mean acquisition time for CS_rt was 22.4 ± 6.2 (SD) s (95% CI: 20.8–23.9 s) versus 442.2 ± 89.9 (SD) s (95% CI: 419.2–465.2 s) for SSFP_ref (p < 0.001). The image quality of CS_rt was diagnostic in all examinations and was mostly rated as good (n = 49/61; 80.3%). There was a high correlation between SSFP_ref and CS_rt images regarding RV ejection fraction (49.8 ± 7.8 (SD)% (95% CI: 47.8–51.8%) versus 48.7 ± 8.6 (SD)% (95% CI: 46.5–50.9%), respectively; r = 0.94) and RV end-diastolic volume (192.9 ± 60.1 (SD) mL (95% CI: 177.5–208.3 mL) versus 194.9 ± 62.1 (SD) mL (95% CI: 179.0–210.8 mL), respectively; r = 0.98). In CS_rt images, tricuspid-regurgitation and wall-motion disorder visualization was good (area under receiver operating characteristic curve (AUC) = 0.87) and excellent (AUC = 1), respectively. Conclusions: Compressed-sensing real-time cine imaging enables, in one breath hold, an accurate assessment of RV function and volumes in CHD patients in comparison with standard SSFP_ref, allowing a substantial improvement in time efficiency.

From Other Journals: A Review of Recent Articles by Our Editorial Team

In this review we provide a brief description of recently published articles addressing topics relevant to pediatric cardiologists. Our hope is to provide a summary of the latest articles published recently in other journals in our field. The articles address (1) The impact of COVID-19 in individuals with congenital heart disease through the life span. Patients with a genetic syndrome and adults at advanced physiological stage were at highest risk for moderate/severe infection. (2) Echocardiographic findings of the multisystem inflammatory syndrome in children showing a high prevalence of myocardial injury and systolic dysfunction that improves in the subacute phase. (3) A score assessment of the Fontan associated liver disease which correlated with the risk for Fontan failure. (4) Grown-up congenital heart surgery in 1093 consecutive cases showed that the 30 day mortality may underestimate the mortaility and that the 6 months mortality is likely a better measure in this population. (5) Cone versus conventional repair for Ebstein's anomaly showed better midterm results and freedom from tricuspid regurgitation after the cone operation. (6) Association between race/ethnicity, illness severity, and mortality in children undergoing cardiac surgery. The study showed that the African American race associated with increased disease severity and thus higher postoperative mortality compared to the caucausian race.

Double-chambered left ventricle: An unusual finding in a middle-aged woman

Double-chambered left ventricle (DCLV) is a rare congenital abnormality and is characterized by the subdivision of the left ventricle into two separate chambers by an abnormal septum or muscle band. This rare congenital entity is usually diagnosed in the neonatal or pediatric age. Nevertheless, it can be asymptomatic and incidentally found in the adulthood. A comprehensive multimodality imaging approach is crucial for the correct final diagnosis.

New developments in adult congenital heart disease

Congenital heart disease (CHD) affects 0.8% of live births and over the past decades technical improvements and large-scale repair has led to increased survival into adulthood of over 95% of the new-born. A new group of patients, those who survived their congenital heart defect, has emerged but late complications including heart failure, pulmonary hypertension (PH), arrhythmias, aneurysms and endocarditis appeared numerous, with a huge impact on mortality and morbidity. However, innovations over the past years have changed the landscape of adult CHD dramatically. In the diagnostic process important improvements have been made in the use of MRI, biomarkers, e‑health concepts and 3D visualisation of anatomy. Care is now concentrated in specialised centres, with a continuous emphasis on education and the introduction of weekly multidisciplinary consultations on diagnosis and intervention. Surgery and percutaneous intervention have been refined and new concepts applied, further reducing the burden of the congenital malformations. Research has matured from case series to global networks. Currently, adults with CHD are still facing high risks of early mortality and morbidity. By global collaboration and continuous education and development and innovation of our diagnostic and therapeutic arsenal, we will improve the perspectives of these young patients.

Adults with congenital heart disease: ready for mobile health?

PURPOSE

Mobile health (mHealth) could improve the outcome of grown-up patients with congenital heart disease (GUCH) and reduce their emergency care utilisation. Inappropriate use of mHealth, however, can lead to data overload for professionals and unnecessary data collection for patients, increasing the burden for both. We aimed to determine the clinical characteristics of patients with high emergency care utilisation and to test whether these patients were willing to start using mHealth.

METHODS

Clinical characteristics and emergency care utilisation of consecutive GUCH patients who visited one of the two participating cardiologists at the outpatient clinic of the Academic Medical Centre in Amsterdam were studied retrospectively. All patients were approached to fill in an mHealth questionnaire. A frequency of three or more emergency visits in 5 years was defined as high emergency care utilisation.

RESULTS

In total, 202 consecutive GUCH patients who visited one of the two participating cardiologists were studied. Median age was 41 years, 47% were male, and 51% were symptomatic. In the previous 5 years, 134 emergency visits were identified. Of all patients, 8% had high emergency care utilisation. High emergency care utilisation was associated with patients being symptomatic, using antiarrhythmic drugs or diuretics. In total, 75% of all patients with high emergency care utilisation were willing to start using mHealth.

CONCLUSION

GUCH patients who are symptomatic, those on antiarrhythmic drug therapy and those on diuretics are suitable candidates for enrolment in future mHealth initiatives because of both high care utilisation and high motivation to start using mHealth.

A successful crowdfunding project for eHealth research on grown-up congenital heart disease patients

BACKGROUND

Scarce data on crowdfunding report a maximal funding of €10.000,-, and state that research is needed to attract attention of larger granting organizations. The aims of this project were 1) to fund an eHealth study in grown-up congenital heart disease (GUCH) patients 2) to contemplate on critical success factors.

METHODS

After peer review of the Dutch Heart Foundation a project was published at a donation platform, which was open for donations during a predetermined period of two months. Copywriters were hired to create an easy-to-understand message to donors. A video teaser was created with a motivated patient, and rewards were available. The crowdfunding targeted €25.000 and the Dutch Heart Foundation doubled the donations to €50.000, and return of donations were guaranteed in case this was not met.

RESULTS

Initially, donations came from the investigators' private inner circle. In total, 44 potential donors were contacted, but refused to donate originally. Multiple (social) media campaigns were published to promote the project, and an offline mailing was sent to contributors to the Dutch Heart Foundation. During the project support emerged, resulting in extra donations and public awareness. In the lasts three weeks, after sufficient private donations, five major donors decided to support the project. The project became a big success: the predetermined target was exceeded and a total of €74.450,- was raised.

CONCLUSION

Innovative crowdfunding gave the opportunity to start eHealth research in GUCH patients. Critical success factors include support of a professional organization, support of stakeholders, and easy-to-understand messages.

Ventricular arrhythmias and sudden death in tetralogy of Fallot

Malignant ventricular arrhythmias and sudden cardiac death may late happen in repaired tetralogy of Fallot, although probably less frequently than previously thought, especially with the advent of new surgical techniques/management. Ventricular tachycardias are caused by reentry around the surgical scars/patches and valves. Many predictive factors have been proposed, which suffer from poor accuracy. There is currently no recommended indication for prophylactic implantable cardioverter defibrillator implantation-except maybe in the case of multiple risk factors-while radiofrequncy ablation may be proposed in secondary prevention with or even without a back-up implantable cardioverter defibrillator in selected cases. Repeated cardiological investigations and monitoring should be proposed for every operated patient.

[Change in our approach in the surgical management of congenital heart defects in patients with Down syndrome, 1974-2016]

INTRODUCTION

Congenital heart defects are frequently present in patients with Down syndrome.

AIM

The authors analyzed the impact of changing approach in surgical management of congenital heart defect on the life expectancy of patients with Down syndrome.

METHOD

Between 1974 and 1997 the data of 359 children with Down syndrome were collected. Among them 255 patients had no surgery and the mortality in this group was 25.9%, whereas the mortality in the group of 104 patients who underwent palliative surgery was 8.6%.

RESULTS

Surgical management of congenital heart defects provides the same life expectancy for these patients as compared to Down patients without cardiac defects. Primary reconstruction is the preferable surgical procedure in infancy that provides good results. Nowadays the number of the operated grown-up congenital heart disease patients with Down syndrome is increasing. During the last three years 82 grown-up congenital heart disease patients, including 4 patients with Down syndrome (aged between 24 and 60 years) were reconstructed successfully.

CONCLUSIONS

Due to the successful surgery in infancy the population of grown-up congenital heart disease patients with Down syndrome is increasing. The cardiac surgeons are ready to do everything for the optimal life expectancy of these patients. However, management of special problems (indication and necessity of reoperation, optimal age) in patients with Down syndrome poses a great challenge for cardiologists and cardiac surgeons. Orv. Hetil., 2016, 157(40), 1601-1603.

Mobile health in adults with congenital heart disease: current use and future needs

Objective

Many adults with congenital heart disease (CHD) are affected lifelong by cardiac events, particularly arrhythmias and heart failure. Despite the care provided, the cardiac event rate remains high. Mobile health (mHealth) brings opportunities to enhance daily monitoring and hence timely response in an attempt to improve outcome. However, it is not known if adults with CHD are currently using mHealth and what type of mHealth they may need in the near future.

Methods

Consecutive adult patients with CHD who visited the outpatient clinic at the Academic Medical Center in Amsterdam were asked to fill out questionnaires. Exclusion criteria for this study were mental impairment or inability to read and write Dutch.

Results

All 118 patients participated (median age 40 (range 18–78) years, 40 % male, 49 % symptomatic) and 92 % owned a smartphone. Whereas only a small minority (14 %) of patients used mHealth, the large majority (75 %) were willing to start. Most patients wanted to use mHealth in order to receive more information on physical health, and advice on progression of symptoms or signs of deterioration. Analyses on age, gender and complexity of defect showed significantly less current smartphone usage at older age, but no difference in interest or preferences in type of mHealth application for the near future.

Conclusion

The relatively young adult CHD population only rarely uses mHealth, but the majority are motivated to start using mHealth. New mHealth initiatives are required in these patients with a chronic condition who need lifelong surveillance in order to reveal if a reduction in morbidity and mortality and improvement in quality of life can be achieved.

Physical activity in patients with grown-up congenital heart defects after comprehensive cardiac rehabilitation

Introduction

The group of grown-up patients with congenital heart defects (grown-up congenital heart – GUCH) complains of a number of specific medical and non-medical problems. The presented program of comprehensive cardiac rehabilitation (CCR-GUCH), dedicated to the above mentioned group, can potentially improve the physical activity of GUCH patients.

Aim

The aim of the study was to assess the effect of the comprehensive cardiac rehabilitation program on the physical activity of GUCH patients.

Material and methods

The invitation to take part in the CCR-GUCH program was addressed to a group of 57 patients (mean age: 23.7 ± 4.1 years) who had undergone the surgical correction of ventricular septal defects (VSD) or atrial septal defects (ASD) at least 12 months earlier. The patients were divided into two groups: A – patients undergoing rehabilitation, and B – patients who did not participate in the program. The patients were initially examined using functional and stress tests, and the program of comprehensive cardiac rehabilitation was started in group A. After 30 days, the patients from both groups underwent further testing using the same methods as during the initial evaluation.

Results

After one month of rehabilitation, the physical activity parameters of patients participating in the CCR-GUCH program (group A) were significantly better than those observed among non-participants (group B).

Conclusions

The introduction of the comprehensive rehabilitation program improves the physical activity and, consequently, the quality of life of GUCH patients. The CCR-GUCH program appears to be a justified supplement to holistic care in the late rehabilitation of patients after the surgical correction of congenital heart defects.

[Surgery of grown up congenital heart disease. About 540 cases]

INTRODUCTION

With advances in recent decades in the field of congenital heart disease both for imaging in medical therapy, a large number of heart disease is diagnosed before birth. Many of them benefit from surgery and reach adulthood, they do not require further action. Some of them develop later in their lives other problems requiring reoperation in adulthood. This sparked the birth of a subspecialty within the department of congenital heart disease: GUCH Unit "grown up congenital heart disease". In developing countries, little heart are detected in childhood, a minority of them are operated and very few reach adulthood or with minor heart disease or become advanced enough then inoperable. Only part may still take advantage of surgery at this age. The aim of our study is to describe the spectrum and characteristics of congenital heart disease in adulthood in Algiers a center of cardiovascular surgery.

POPULATION AND METHODS

A retrospective descriptive study of patients aged 15 and above operated for congenital heart defects between 1995 and 2011.

RESULTS

Five hundred and forty patients aged 15 to 76years (29±10 years), including 314 women and 226 men are operated congenital heart defects between 1995 and 2011. The left-right shunts represent two thirds of heart disease, represented mainly (50%) by the atrial septal defect. Barriers to the ejection of the left heart represent one forth of cases with a predominance of subvalvular aortic stenosis. We find the native heart whose survival is considered exceptional in adulthood in the absence of surgery, such as tetralogy of Fallot, aortopulmonary windows wide, double outlet right ventricle and atrioventricular canal that take advantage of always surgery. The results are encouraging with low perioperative mortality (2%).

CONCLUSION

The approach of congenital heart disease in developing countries is different from that of developed countries. Efforts need to be made in early detection and monitoring of congenital heart disease and improve access to surgery centers in close collaboration with pediatricians, cardiologists and obstetricians.

Right Ventricular Overload Due to Severe Pulmonary Valve Regurgitation in 44-Year-Old GUCH

Notoriously, the valvular disease of the right heart have always received less attention than the left heart valvular disease both by echocardiographers and by researchers, probably due to the long period of latent asymptomatic and for the intrinsic difficulties of examination. However, it is increasingly recognized that right-sided valve disease is not a benign lesion and has a significant and independent impact on morbidity and mortality. Pulmonary regurgitation (PR) is common after surgical or percutaneous relief of pulmonary stenosis and following repair of tetralogy of Fallot. This case report describes the natural history of an adult patient with grown-up congenital heart (GUCH) who became competitive athlete and who showed signs of extreme morphological and functional adaptation of the right heart resulting in the outcome of a previous run surgical valvotomy at the age of 5 years for a congenital pulmonary stenosis. These anatomic changes of the right ventricle and pulmonary circulation have requested the replacement of the pulmonary valve for the symptomatic pulmonary hypertension, with subsequent gradual return to sports activity.
