Performance and Failure of Right Ventricle to Pulmonary Artery Conduit in Congenital Heart Disease. Am J Cardiol 2024; 226:50-58. [PMID: 38986860 DOI: 10.1016/j.amjcard.2024.06.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2024] [Revised: 05/26/2024] [Accepted: 06/14/2024] [Indexed: 07/12/2024]
Abstract
Surgical implantation of a right ventricle to pulmonary artery (RV-PA) conduit is an important component of congenital heart disease (CHD) surgery, but with limited durability, leading to re-intervention. The present single-center, retrospective, cohort study reports the results of surgically implanted RV-PA conduits in a consecutive series of children and adults with CHD. Patients with CHD referred for RV-PA conduit surgical implantation (from October 1997 to January 2022) were included. The primary outcome was conduit failure, defined as a peak gradient above 64 mm Hg, severe regurgitation, or the need for conduit-related interventions. Longitudinal echocardiographic studies were available for mixed-effects linear regression analysis. A total of 252 patients were initially included; 149 patients were eligible for follow-up data collection. After a median follow-up time of 49 months, the primary study end point occurred in 44 (29%) patients. A multivariable Cox regression model identified adult age (>18 years) at implantation and pulmonary homograft implantation as protective factors (hazard ratio 0.11, 95% confidence interval [CI] 0.02 to 0.47 and hazard ratio 0.34, 95% CI 0.16 to 0.74, respectively). Fever within 7 days of surgical conduit implantation was a risk factor for early (within 24 months) failure (odds ratio 4.29, 95% CI 1.41 to 13.01). Long-term use of oral anticoagulants was independently associated with slower progression of peak echocardiographic gradient across the conduits (mixed-effects linear regression p = 0.027). In patients with CHD, the rate of failure of surgically implanted RV-PA conduits is higher in children and after nonhomograft conduit implantation. Early fever after surgery is a strong risk factor for early failure. Long-term anticoagulation seems to exert a protective effect.

Am J Cardiol 2024:S0002-9149(24)00597-6. [PMID: 39147304 DOI: 10.1016/j.amjcard.2024.08.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2024] [Revised: 08/07/2024] [Accepted: 08/09/2024] [Indexed: 08/17/2024]
Abstract
Transcatheter pulmonary valve replacement (TPVR) is now frequently performed in patients with adult congenital heart disease. As the life expectancy of the population with adult congenital heart disease continues to improve, more patients will require pulmonary valve intervention. This study details the short-term and midterm clinical outcomes of patients aged ≥40 years who underwent TPVR. We performed an institutional retrospective cohort study that included patients aged ≥40 years who underwent TPVR (and clinical follow-up) from January 1, 2012 to January 1, 2024. Descriptive analyses, Kaplan-Meier survival analysis, and Cox proportional hazard modeling were used to determine outcomes and risk factors affecting survival. The study included 67 patients, and median age at TPVR was 48 years (43 to 57). Median hospital length of stay after TPVR was 1 day (1 to 3); periprocedural complications occurred in 5 patients, and acute kidney injury occurred in 1 patient. Median duration of follow-up was 3.5 years (0.1 to 9.7). There were 9 total deaths, and 1-, 3-, and 5-year Kaplan-Meier survival after TPVR was 95%, 91%, and 82%, respectively. Moderate or worse right ventricular dysfunction was present in 22 patients before TPVR and in 20 patients after TPVR. Inpatient status before TPVR negatively affected survival (hazard ratio 24.7, 3.3 to 186.1, p = 0.002). In conclusion, TPVR was performed in patients aged ≥40 years with favorable periprocedural and midterm follow-up outcomes including survival, but right ventricular dysfunction did not improve, and further exploration of the ideal timing of TPVR in this age group is warranted.

In vitro bench testing using patient-specific 3D models for percutaneous pulmonary valve implantation with Venus P-valve. Chin Med J (Engl) 2024; 137:990-996.

Abstract
BACKGROUND Due to the wide variety of morphology, size, and dynamics, selecting an optimal valve size and location poses great difficulty in percutaneous pulmonary valve implantation (PPVI). This study aimed to report our experience with in vitro bench testing using patient-specific three-dimensional (3D)-printed models for planning PPVI with the Venus P-valve. METHODS Patient-specific 3D soft models were generated using PolyJet printing with a compliant synthetic material in 15 patients scheduled to undergo PPVI between July 2018 and July 2020 in Central China Fuwai Hospital of Zhengzhou University. RESULTS 3D model bench testing altered treatment strategy in all patients (100%). One patient was referred for surgery because testing revealed that even the largest Venus P-valve would not anchor properly. In the remaining 14 patients, valve size and/or implantation location was altered to avoid valve migration and/or compression coronary artery. In four patients, it was decided to change the point anchoring because of inverted cone-shaped right ventricular outflow tract (RVOT) ( n = 2) or risk of compression coronary artery ( n = 2). Concerning sizing, we found that an oversize of 2-5 mm suffices. Anchoring of the valve was dictated by the flaring of the in- and outflow portion in the pulmonary artery. PPVI was successful in all 14 patients (absence of valve migration, no coronary compression, and none-to-mild residual pulmonary regurgitation [PR]). The diameter of the Venus P-valve in the 3D simulation group was significantly smaller than that of the conventional planning group (36 [2] vs. 32 [4], Z = -3.77, P <0.001). CONCLUSIONS In vitro testing indicated no need to oversize the Venus P-valve to the degree recommended by the balloon-sizing technique, as 2-5 mm sufficed.

Abstract
BACKGROUND Pulsta valve is increasingly used for percutaneous pulmonary valve implantation (PPVI) in patients with a large native right ventricular outflow tract (RVOT). This study aims to elucidate the outcomes of Pulsta valve implantation within the native RVOT and assess its adaptability to various native main pulmonary artery (PA) anatomies. METHODS A multicenter retrospective study included 182 patients with moderate to severe pulmonary regurgitation in the native RVOT who underwent PPVI with Pulsta valves® between February 2016 and August 2023 at five Korean and Taiwanese tertiary referral centers. RESULTS Pulsta valve implantation was successful in 179 out of 182 patients (98.4%) with an average age of 26.7 ± 11.0 years. The median follow-up duration was 29 months. Baseline assessments revealed enlarged right ventricle (RV) volume (mean indexed RV end-diastolic volume: 163.1 (interquartile range, IQR: 152.0-180.3 mL/m²), which significantly decreased to 123.6(IQR: 106.6-137.5 mL/m2 after 1 year. The main PA types were classified as pyramidal (3.8%), straight (38.5%), reverse pyramidal (13.2%), convex (26.4%), and concave (18.1%) shapes. Pulsta valve placement was adapted, with distal main PA for pyramidal shapes and proximal or mid-PA for reverse pyramidal shapes. Two patients experienced Pulsta valve embolization to RV, requiring surgical removal, and one patient encountered valve migration to the distal main PA, necessitating surgical fixation. CONCLUSIONS Customized valve insertion sites are pivotal in self-expandable PPVI considering diverse native RVOT shape. The rather soft and compact structure of the Pulsta valve has characteristics to are adaptable to diverse native RVOT geometries.

Abstract
OBJECTIVE The purpose of this study is to assess the feasibility, effectivity, and safety of a novel self-expandable valve system, Pulsta® transcatheter heart valve in patients with tetralogy of fallot and severe pulmonary regurgitation after transannular patch repair. BACKGROUND Severe pulmonary regurgitation after tetralogy of fallot repair is a life-threatening problem and should be treated by pulmonary valve implantation. Although percutaneous pulmonary valve implantation has been ever increasingly used for this purpose, available balloon-expandable valves have limitations and cannot be used by most patients. Pulsta® transcatheter heart valve is a new self-expandable valve system and offers a new solution to be used in patients with different types of native right ventricular outflow tract geometry. PATIENTS AND METHODS Ten patients with severe regurgitation after tetralogy of fallot repair with a transannular patch have been enrolled in the study according to echocardiographic examination. MRI was used in asymptomatic patients to delineate the indication and the right ventricular outflow tract geometry. Pulsta® transcatheter heart valve implantation was performed in ten patients, and preprocedural, procedure, and 6 months follow-up findings of the patients were evaluated. RESULTS Pulsta® pulmonary valve implantation was performed in ten patients successfully without any severe complications. Valve functions were perfect in six of ten patients, while the others had insignificant regurgitation by echocardiographic examination at the end of 6 months follow-up. CONCLUSIONS This study showed that Pulsta® transcatheter heart valve is a feasible, effective, and safe method in the treatment of severe pulmonary regurgitation due to transannular patch repair in patients with tetralogy of fallot.

Abstract
The implantation of percutaneous balloon expandable valves in native or patched right ventricular outflow tracts (nRVOT) is a challenging technique due to the diversity of anatomies and shapes, the large sizes, and the distensibility of the nRVOT, for which specific techniques have been developed. We present a single center experience with balloon expandable percutaneous pulmonary valves in nRVOT, describing the techniques used, complications observed, and a short-mid term follow-up.. This is a single center descriptive study of patients who underwent a percutaneous pulmonary valve implantation in a nRVOT with a balloon expandable pulmonary valve in our center between September 2012 and June 2022.. We implanted successfully 45 valves in 46 patients (20 Sapien and 25 Melody). Tetralogy of Fallot or pulmonary atresia with VSD were the main congenital heart disease (n = 32). All were pre-stented, 18 in a one step procedure. We used a Dryseal sheath in 13/21 Sapien. In 6 patients we used the anchoring technique, 5 with a very large nRVOT and one pyramidal nRVOT. In the 3.5 year follow-up 7 patients developed endocarditis and 3 required a valve redilation, no fractures were observed. PPVI of native RVOT with balloon expandable valves is feasible in a number of selected anatomies, including large or pyramidal nRVOT, using specific techniques, (presenting, LPA anchoring).

Abstract
BACKGROUND Many patients with repaired tetralogy of Fallot require reoperation in the medium to long-term for residual pulmonary valve regurgitation. Best timing for pulmonary valve replacement remains controversial. A balance needs to be found between protecting the patients from permanent right ventricular damage and insertion of a prosthetic valve with its inherent issues. In the current study we sought to investigate the right and left ventricular functional recovery following valve replacement in our tertiary care institution. RESULTS In a retrospective cross-sectional study patients with history of total correction of tetralogy of Fallot who had undergone pulmonary valve replacement due to severe pulmonary regurgitation between 2003-2018 were evaluated for post intervention right and left ventricular functional recovery. Clinical and full echocardiographic data before and after the surgery were recorded and compared. There was statistically significant improvement in RV size and function post pulmonary valve replacement. There was no statistically significant improvement in left ventricular systolic function. Twenty percent of patient had persisting severe right ventricular enlargement at least twelve months post-surgery. No patient had fully normalized right ventricular size and function in follow-up. CONCLUSIONS Pulmonary valve replacement leads to improvement in right ventricular size and function in patients with repaired tetralogy of Fallot. However normalization of functional parameters did not occur and the majority of the patients have residual right and left ventricular dysfunction following redo valve replacement surgery.

Abstract
Surgical repair of a variety of congenital heart diseases involves repair of the right ventricular outflow tract (RVOT) with valved or non-valved conduit to connect the right ventricle (RV) to the pulmonary artery (PA) or just patch enlargement of the native RVOT. With time, this RV-PA conduit will degenerate with deterioration of function, either causing pulmonary stenosis or pulmonary regurgitation. This RVOT dysfunction may result in RV dilation, RV dysfunction, and eventual RV failure and arrhythmias. Multiple surgical pulmonary valve replacement (PVR) is often required throughout the patient's lifetime. Patients are subjected to increased risks with each additional cardiac operation. Transcatheter PVR (TPVR) has been developed over the past two decades as a valuable non-surgical alternative to restore the RVOT and RV function, and hence reduce patients' lifetime risks related to surgery. This article will discuss the long-term results of TPVR which are demonstrated to be comparable to surgical results and the latest development of large pulmonary valves which will allow TPVR to be performed on native or larger RVOT.

Abstract
OBJECTIVE This study sought to investigate the characteristics, morbidity (including the rate of infective endocarditis and valve replacement) and mortality of individuals undergoing percutaneous pulmonary valve implantation in Australia and New Zealand since the procedure has been performed. BACKGROUND The outcomes of percutaneous pulmonary valve implantation in Australia and New Zealand have not been evaluated. Recent international data, including patients from New Zealand, suggests the rate of infective endocarditis is not insignificant. METHODS A retrospective multi-site cohort study was undertaken via medical record review at the centres where percutaneous pulmonary valve implantation has been performed. All procedures performed from 2009-March 2018 were included. Individuals were identified from local institution databases. Data was collected and analysed including demographics, details at the time of intervention, haemodynamic outcome, post procedure morbidity and mortality. Multi-site ethics approval was obtained. RESULTS One hundred and seventy-nine (179) patients attended the cardiac catheter laboratory for planned percutaneous pulmonary valve implantation. Of these patients, 172 underwent successful implantation. Tetralogy of Fallot and pulmonary atresia were the most common diagnoses. The median age at procedure was 19 years (range 3-60 yrs). There was a significant improvement in the acute haemodynamics in patients undergoing percutaneous pulmonary valve implantation for stenosis. Seven (7) patients (3.9%) experienced a major procedural/early post procedure complication (death, conversion to open procedure, cardiac arrest), including two deaths. The annualised rates of infective endocarditis and valve replacement were 4.6% and 3.8% respectively. There was one death related to infective endocarditis in follow-up. CONCLUSIONS Percutaneous pulmonary valve replacement is a relatively safe method of rehabilitating the right ventricular outflow tract.

Abstract
The majority of patients with congenital heart disease who have undergone open heart surgery during childhood are possible candidates for additional transcatheter or surgical interventions. One fifth of these conditions usually involve the right ventricular outflow tract (RVOT). Percutaneous pulmonary valve replacement (PPVR) has been widely established as an alternative, less invasive option to surgical pulmonary valve replacement (SPVR). The variability of RVOT anatomy and size, the relative course of the coronary arteries and the anatomy of the pulmonary artery branches are factors that determine the success of the intervention as well as the complication rates. Careful and reliable pre-interventional imaging warrants the selection of suitable candidates and minimizes the risk of complications. 2D and 3D fluoroscopy have been extensively used during pre- and peri-interventional assessment. Established imaging techniques such as Cardiovascular Magnetic Resonance (CMR) and Computed Tomography (CT), as well as newer techniques, such as fusion imaging, have proved to be efficient and reliable tools during pre-procedural planning in patients assessed for PPVR.

Abstract
OBJECTIVES The aim of this study was to compare the immediate and midterm echocardiographic performance of the Melody (Medtronic Inc) and Sapien (Edwards Lifesciences Inc) valves after transcatheter pulmonary valve replacement (TPVR) in native and conduit right ventricular outflow tracts (RVOTs). BACKGROUND TPVR is now a common procedure, but limited data exist comparing postimplantation echocardiographic findings between Melody and Sapien valves. METHODS This was a single-institution retrospective cohort study of all patients who underwent successful TPVR from 2011 to 2020. Patient demographics, procedural details, and immediate and midterm echocardiographic findings were collected and compared between valve types using the Wilcoxon rank sum, chi-square, or Fisher exact test as appropriate. Subgroups were analyzed individually and were adjusted for multiple comparisons using the Bonferroni method. RESULTS A total of 328 patients underwent successful TPVR (Melody: n = 202, Sapien: n = 126). The groups had a similar baseline age, weight, and diagnosis. The most common indications for TPVR were pulmonary stenosis (32.2%) or mixed disease (46%) in the Melody group and pulmonary insufficiency in the Sapien group (52.4%) (P < 0.001). Sapien valves were more often placed in native RVOTs (43.7% vs 18.8%; P < 0.001). The discharge and follow-up mean and peak Doppler gradients were similar between the Melody and Sapien groups. Valves implanted in native RVOTs had significantly lower postimplantation gradients at each follow-up period. CONCLUSIONS Echocardiographic performance after TPVR was generally acceptable and similar when comparing Melody and Sapien valves despite differences in the indication and anatomy in each group. The peak and mean gradients were lower in transcatheter valves implanted in native RVOTs compared with those implanted in conduits or bioprosthetic valves.

Abstract
OBJECTIVES Since percutaneous pulmonary valve implantation (PPVI) was introduced to prolong the lifetime of surgically placed right ventricular to pulmonary artery conduits, valve technology has evolved and the indications for PPVI expanded to native and larger right ventricular outflow tracts. We explore how indications, patient populations and outcomes compare to surgical pulmonary valve replacement (PVR). METHODS This is a retrospective cohort study of PPVI and PVR procedures between 1998 and 2020 at a single UK centre. One hundred and twenty-eight patients underwent PPVI and 365 patients PVR. Primary outcome measures were survival, infective endocarditis and reintervention. RESULTS The most common indication for PVR was replacement of the native pulmonary valve for pulmonary regurgitation whereas PPVI was more commonly used to treat pulmonary stenosis in a previously placed bioprosthetic conduit or valve. Treatment indications for PPVI expanded over the study to include the native right ventricular outflow tract. Survival was similar for PPVI and PVR (92% PPVI and 96.8% PVR at 5 years; 85.8% PPVI and 95.1% PVR at 10 years). Preprocedural New York Heart Association class 3 and 4 was the most important predictor of poor outcome. Annualized infective endocarditis rate was significantly higher for the Melody PPVI (0.024 vs 0.0024/person/year for PVR, P < 0.05). Both groups showed significant symptomatic improvement postprocedure with remodelling of ventricular volumes and improvement in cardiac output. Long-term follow-up for PVR showed half of patients will need replacement at 10-15 years post-index procedure. CONCLUSIONS An increasing number of patients requiring PVR can now be treated percutaneously. A lifetime strategy for re-valving should be considered at the first valve implant.

Abstract
OBJECTIVES The aim of this study is to present the mid-term outcomes of Pulsta valve. BACKGROUND The Pulsta valve is a Self-expandable knitted nitinol-wire stent mounted with a treated tri-leaflet α-Gal-free porcine pericardial valve for percutaneous pulmonary valve implantation (PPVI) in patients with native right ventricular outflow tract (RVOT) lesions. METHODS A multi-center clinical trial using Pulsta valve® was designed for patients with severe pulmonary regurgitation (PR) in the native RVOT in multiple centers in South Korea and 25 patients were enrolled. Before PPVI, severe PR (mean PR fraction: 45.5 ± 6.9%) and enlarged RV volume (mean indexed RV end-diastolic volume; 169.7 ± 13.0 ml/m2 ) was present. The mean age was 21.6 ± 6.6 years old. RESULTS All patients were successfully implanted with 26, 28, or 32 mm diameter of Pulsta valve loaded on the 18 or 20 French delivery catheters. At 6 months follow up, indexed RV end-diastolic volume was decreased to 126.9 ± 16.9 ml/m2 . At mean 33.1 ± 14.3 months follow-up, the mean value of mean pressure gradient in Pulsta valve was 6.5 ± 3.0 mmhg without significant PR. There was no serious device-related adverse event. CONCLUSIONS A multi-center clinical trial was completed successfully with planned Pulsta valve implantation and demonstrated good mid-term effectiveness without device-related serious adverse events.

Abstract
Pulmonary regurgitation is the most important sequellae after correction of Tetralogy of Fallot and has a considerable impact over the right ventricle. Surgery has demonstrated low early mortality after pulmonary valve replacement and good long-term outcomes, remaining nowadays the gold standard treatment of pulmonary regurgitation in rTOF patients. Nevertheless, transcatheter pulmonary valve implantation has emerged as a new, safe and efficient alternative to surgical valve replacement. In this review article, we try to evaluate and compare both techniques to find out which is the best therapeutic option in this patients.

Abstract
Importance National guidelines recommend cardiac rehabilitation (CR) after cardiac valve surgery, and CR is covered by Medicare for this indication. However, few data exist regarding current CR enrollment after valve surgery. Objective To characterize CR enrollment after cardiac valve surgery and its association with outcomes, including hospitalizations and mortality. Design, Setting, and Participants This cohort study of patients undergoing valve surgery was conducted in calendar year 2014, with follow-up through 2015. The study included all fee-for-service Medicare beneficiaries undergoing open cardiac valve surgery in 2014. Patients identified by inpatient diagnosis codes for open aortic, mitral, tricuspid, and pulmonary valve surgery were included. Data analysis occurred from January 2018 to March 2019. Exposures Logistic regression was used to evaluate sociodemographic and clinical factors associated with CR enrollment. Main Outcomes and Measures We used Andersen-Gill models to evaluate the association of CR enrollment with 1-year hospitalization risk and Cox regression models to evaluate the association of CR enrollment with 1-year mortality risk. Results A total of 41 369 Medicare beneficiaries (median [interquartile range] age, 73 [68-79] years; 16 935 [40.9%] female) underwent open valve surgery in the United States in 2014. Fewer than half of patients (17 855 [43.2%]) who had valve surgery enrolled in CR programs. Several racial/ethnic groups had lower odds of enrolling in CR programs after valve surgery compared with white patients, including Asian patients (odds ratio [OR], 0.36 [95% CI, 0.28-0.47]), black patients (OR, 0.60 [95% CI, 0.54-0.67]), and Hispanic patients (OR, 0.36 [95% CI, 0.28-0.46]). Patients undergoing concomitant coronary artery bypass grafting had higher odds of CR enrollment (OR, 1.26 [95% CI, 1.20-1.31]) than those without the concomitant coronary artery bypass graft procedure, as did patients in the Midwest census region (OR, 2.40 [95% CI, 2.28-2.54]) compared with those in the South (reference). Cardiac rehabilitation enrollment was associated with fewer hospitalizations within 1 year of discharge (hazard ratio, 0.66 [95% CI, 0.63-0.69] after multivariable adjustment). Enrollment was also associated with a 4.2% absolute decrease in 1-year mortality risk (hazard ratio, 0.39 [95% CI, 0.35-0.44] after multivariable adjustment). Conclusions and Relevance Fewer than half of Medicare beneficiaries undergoing cardiac valve surgery enroll in CR programs, and there are marked racial/ethnic disparities among those that do. Cardiac rehabilitation is associated with decreased 1-year cumulative hospitalization and mortality risk after valve surgery. These results invite further study on barriers to CR enrollment in this population.

Abstract
Tetrallogy of Fallot (TOF) is the most frequent form of cyanotic congenital heart disease. Despite advances in surgical and medical treatment, mortality remains high. Residual dysfunction of the pulmonary valve (PV) after correction of right ventricular outflow tract obstruction is an important cause of morbidity, leading to irreversible right ventricular dysfunction, arrhythmias, heart failure and occasionally, death. The strategies for PVR have evolved over the last decades, and the timing of the intervention remains the foundation of the decision-making process. Symptoms of heart failure are unreliable indicators for optimal timing of repair. Imaging plays an essential role in the assessment of PV integrity and dysfunction. The identification of the best timing for PVR requires a multimodality approach. Transthoracic echocardiography is the most commonly used imaging modality for the initial assessment and follow-up of TOF patients, although its utility has technical limitations, especially in adults. Cardiac computed tomography and magnetic resonance imaging are now routinely used for preoperative and postoperative evaluation of these patients, and provide highly valuable information about the anatomy and pathophysiology. Imaging evidence of disease progression is now part of the major guidelines to define the best timing for reintervention. The purpose of this article is to review the pathophysiology after TOF repair, identify the main imaging anatomic and physiologic features, describe the indications for PVR and recognize the role of imaging in the assessment of these patients to define the appropriate timing of PVR.

Abstract
OBJECTIVE Percutaneous pulmonary valve implantation (PPVI) into right ventricle-to-pulmonary artery conduits is increasingly being performed, but a few options are available for patients with a dilated native right ventricular outflow tract (RVOT), among which is the off-label use of Ed-wards SAPIEN® valves. This study reviews the results of the SAPIEN XT and SAPIEN 3 (S3) valve implantations in the pulmonary position in patients with a dilated native RVOT. METHODS Between January 2015 and March 2020, PPVI procedures were performed on 129 patients. Among them, 103 (80%) had dilated native RVOT, 86 of whom were eligible for PPVI prestenting and valve implantation. Retrospective analysis was performed on 84 patients who have undergone successful PPVI implantation using the SAPIEN XT or S3 valves with dilated native RVOT. RESULTS The procedural success rate was 84/86 (98%). The median age was 18.7 years (8-46 years), and the median weight was 57 kg (22-102 kg). The primary underlying diagnosis was tetralogy of Fallot (n=77/84). Stenting was performed simultaneously with valve implantation in 50/84 (60%) cases-six of which were hybrid procedures-whereas prestenting was performed 3 to 14 weeks earlier in 34/84 cases. Before valve im-plantation, the median right anterior oblique and lateral diameters of the stents were 26 mm (20-32 mm) and 28 mm (21-32 mm). Valve sizes were 26 mm (n=13) and 29 mm (n=64) for XT and 29 mm (n=7) for S3. In 59 patients, an additional 1-5 ml (median 2 ml) volume was added to the valves' balloons for stabilization. In all hybrid procedures, the stent and valve were implanted in the same session. During follow-ups of 1 to 59 months (median 14 months), no deaths were reported, 3 patients developed tricuspid regurgitation secondary to the procedure, and valves continued to function in all patients. CONCLUSION The Edwards SAPIEN XT and S3 valves may be an alternative to PPVI in patients with dilated native RVOT.

Abstract
Percutaneous pulmonary valve implantation (PPVI) is recognized as a feasible and low risk alternative to surgery to treat dysfunctional right ventricular outflow tract (RVOT) in usually pluri-operated patients. Evolving technology allowed to develop different kind of prosthesis and to go from an initial treatment exclusively of stenotic conduit to an actual approach extended also to wide native RVOT. The Melody transcatheter pulmonary valve (TPV) and the Edwards Sapien valve are nowadays the most commonly implanted prostheses. However, other devices have been developed to treat large RVOT (i.e., the Venus p-valve, the Medtronic Harmony TPV, the Alterra Adaptive Prestent, and the Pulsta valve). Indications for PPVI are the same as for surgical interventions on pulmonary valve, with limits related to the maximum diameter of the available percutaneous prosthesis. Therefore, an accurate preoperative evaluation is of paramount importance to select patients who could benefit from this procedure. The overall periprocedural mortality incidence is around 1.4%, while freedom from RVOT reintervention ranges from 100% at 4 months to 70% at 70 months, according to the different published studies.

Abstract
BACKGROUND Self-expandable percutaneous pulmonary valve implantation (PPVI) for native right ventricular outflow tract lesions is still in the clinical trial phase. The aim of this study is to present the result of feasibility study of a novel self-expandable knitted nitinol wire stent mounted with a treated trileaflet α-Gal-free porcine pericardial valve for PPVI. METHODS AND RESULTS A feasibility study using Pulsta valve (TaeWoong Medical Co, Gyeonggi-do, South Korea) was designed for patients with severe pulmonary regurgitation in the native right ventricular outflow tract, and 6-month follow-up outcomes were reviewed. Ten tetralogy of Fallot patients were enrolled. Before PPVI, severe pulmonary regurgitation (mean pulmonary regurgitation fraction, 45.5%±7.2%; range, 34.9%-56%) and enlarged right ventricular volume (mean indexed right ventricular end-diastolic volume, 176.7±14.3 mL/m2; range, 158.9-205.9 mL/m2) were present. The median age at PPVI was 21.7±6.5 years (range, 13-36 years). Five patients were successfully implanted with 28 mm and the other 5 with 26 mm valves loaded on the 18F delivery cable. No significant periprocedural complications were noted in any patient. At the 6-month follow-up, indexed right ventricular end-diastolic volume was dramatically decreased to 126.3±20.3 mL/m2 (range, 99-164.2 mL/m2), and the mean value of peak instantaneous pressure gradient between the right ventricle and the pulmonary artery decreased from 6.8±3.5 mm Hg (range, 2-12 mm Hg) before PPVI to 5.7±6.7 mm Hg (range, 2-12 mm Hg) without significant pulmonary regurgitation. There was no adverse event associated with the valve. CONCLUSIONS A feasibility study of the Pulsta valve for native right ventricular outflow tract lesions was completed successfully with planned Pulsta valve implantation and demonstrated good short-term effectiveness without serious adverse events.

Abstract
BACKGROUND Twenty percent of patients born with congenital heart disease present with right ventricular outflow tract abnormalities. These patients require multiple surgical procedures in their lifetime. Transcatheter pulmonary valve replacement (TPVR) has become a viable alternative to conventional pulmonary valve and right ventricular outflow tract surgery in pediatric and adult populations. In this retrospective review, we analyze the perioperative management of adult patients who underwent TPVR in our center. METHODS The study consisted of a chart review of patients who underwent TPVR at Toronto General Hospital between 2006 and 2015. Information about preoperative assessment, intraoperative anesthetic management, and intra- and postprocedural complications was collected. Two types of percutaneous valves have been used for a conduit or valve size between 16 and 28 mm. These procedures are done via the femoral, jugular, or subclavian vein under general anesthesia. RESULTS Seventy-nine adults (17-68 years of age) who underwent elective TPVR procedures were included. General anesthesia was used in all cases. Defibrillation was necessary in 1 case, and bradycardia was spontaneously resolved in another 1. Eighty-five percent were successfully extubated at the end of the procedure. Five patients required intraoperative inotropic support. Three patients presented self-resolved hemoptysis. Mechanical ventilation for >24 hours was necessary in 3 cases, 2 of which also required concomitant inotropic support. Four failed deployments and 1 case of persistent conduit stenosis were reported. Three patients required reintubation. All patients were discharged home. CONCLUSIONS Patients undergoing TPVR represent a complex and heterogeneous population. General anesthesia with endotracheal intubation is preferred. Setup for urgent lung isolation and cardiac defibrillation should be considered. Postoperative monitoring and intensive care setting are required. Anesthesiologists with cardiac anesthesia training are probably better suited to manage these patients.

A word of caution: diabolic behaviour of AndraStents®: inflation of supporting balloon leads to "diabolo"-misconfiguration of the stent. Cardiol Young 2019; 29:972-976.

Abstract
AIMS Transcatheter implantation of pulmonary balloon-expandable stent-valves requires pre-stenting of the right ventricular outflow tract with large calibre stents. To increase awareness of the associated risks of this part of transcatheter pulmonary valve replacement therapy, we report potential fatal complications during the implantation of AndraStents® in the right ventricular outflow tract in six cases from five different European institutions and their management. METHOD AND RESULT We present a retrospective case series analysis looking at the time period from 2013 to 2018. Of 127 AndraStents® implanted in the right ventricular outflow tract, in six patients, age from 13 to 71 years, a misconfiguration of the AndraStent® occurred forming a "diabolo"-configuration. During inflation of the balloon, the stent showed extreme "dog-boning", an expansion of the stent at both ends with the middle part remaining unexpanded. This led to rupture of the balloon and loss of manoeuvrability in four patients. Out of the total six cases, in four patients the stent was eventually expanded with high-pressure balloons, and in one case the stent was surgically retrieved. In one patient, in whom a percutaneous retrieval of the embolised stent was attempted, a fatal bleeding occurred. CONCLUSIONS Pre-stenting of the right ventricular outflow tract by AndraStents® can lead to misconfiguration of the stent with potentially fatal complications. Rescue strategies of misconfigured stents include stent inflation and placement with high pressure non-compliant balloons or surgical backup. Interventional retrieval measures of AndraStents® cannot be advised.

Abstract
BACKGROUND Percutaneous pulmonary valve implantation (PPVI) has been established as a safe and effective alternative to surgery treating patients with a failing pulmonary valve conduit. Nevertheless, the majority of patients in need of a valve have a native, non-obstructive right ventricular outflow tract (RVOT). The current approved stent-valves have a balloon-expandable design. Pre-stenting of the RVOT to create a landing zone and also protect the valve stability is usually mandatory; large, non-obstructive RVOTs need pre-stenting to reduce the RVOT-diameter for a balloon-expandable valve implantation. METHODS A retrospective study design was used to analyze the medium-term outcome after PPVI in a series of 26 patients with native or reconstructed RVOT. RESULTS PPVI was successfully performed in all, but 1 (96%). Within the follow-up of a minimum of 2 years, the percutaneous implanted valves remained competent; a significant pressure gradient was not detected. Furthermore, no PPVI-related complications such as endocarditis, migration or stent fractures were observed. The electrocardiogram at rest, in particular the QRS duration remained unchanged immediate post-PPVI as well as at medium-term follow-up of 24 months. However, ventricular arrhythmias were documented in 3 patients (11.5%); all patients were successfully treated with antiarrhythmic drugs, utilizing metoprolol. A trial of an invasive catheter based RVOT-ablation in one remained unsuccessful; pre-stented RVOT did not allow a successful intervention. CONCLUSIONS Medium-term follow-up showed excellent results of the mechanical valve function. PPVI utilizing balloon-expandable stent-valves in a native RVOT remains an off-label use. Despite our encouraging results, advanced manipulations of the patched or native RVOT might be associated with significant ventricular arrhythmias. There is a need for less invasive RVOT reduction devices.

Magnetic resonance and computed tomography imaging fusion for live guidance of percutaneous pulmonary valve implantation. ADVANCES IN INTERVENTIONAL CARDIOLOGY 2018; 14:413-421. [PMID: 30603031 PMCID: PMC6309845 DOI: 10.5114/aic.2018.79871] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2018] [Accepted: 09/18/2018] [Indexed: 11/20/2022] Open
Abstract
Introduction Until recently, two-dimensional (2D) angiography was the mainstay of guidance for percutaneous pulmonary valve implantation (PPVI). Recent advances in fusion software have enabled direct fusion of pre-intervention imaging, magnetic resonance imaging (MRI) or computed tomography (CT) scans, to create a reliable three-dimensional (3D) roadmap for procedural guidance. Aim To report initial two-center experience with direct 2D–3D image fusion for live guidance of PPVI with MRI- and CT-derived 3D roadmaps. Material and methods We performed a prospective study on PPVIs guided with the new fusion imaging platform introduced in the last quarter of 2015. Results 3D guidance with an MRI- (n = 14) or CT- (n = 8) derived roadmap was utilized during 22 catheterizations for right ventricular outflow tract balloon sizing (n = 7) or PPVI (n = 15). Successful 2D–3D registration was performed in all but 1 patient. Six (27%) patients required intra-procedural readjustment of the 3D roadmap due to distortion of the anatomy after introduction of a stiff wire. Twenty-one (95%) interventions were successful in the application of 3D imaging. Patients in the CT group received less contrast volume and had a shorter procedural time, though the differences were not statistically significant. Those in the MRI group had significantly lower weight adjusted radiation exposure. Conclusions With intuitive segmentation and direct 2D–3D fusion of MRI or CT datasets, VesselNavigator facilitates PPVI. Our initial data show that utilization of CT-derived roadmaps may lead to less contrast exposure and shorter procedural time, whereas application of MRI datasets may lead to lower radiation exposure.

Abstract
BACKGROUND Coronary compression (CC) is a life threatening complication that can occur during percutaneous pulmonary valve implantation (PPVI). We describe our experience using cardiac CT prior to PPVI to identify patients at high CC-risk due to a close relationship between the coronary arteries and pulmonary trunk (PT). METHODS A retrospective evaluation of candidates for PPVI who underwent CT prior to the procedure was done. Measurements of PT were performed using double oblique reconstructed images, with special attention to the stenotic tract of the PT. The analysis of coronary arteries included detection of anomalies of origin and course and assessment of their relationship with the PT, measuring the minimum distance between the coronary artery and the intended site of the future percutaneous valve implantation. RESULTS CT analysis was performed for 52 patients. Thirty patients underwent PPVI after CT and 22 didn't. In 6/22 cases the reason not to receive a PPVI was high CC-risk detected at CT. In 6 other patients CT detected an intermediate CC-risk but the test balloon performed during angiography prior to valve placement was safe and the patients successfully underwent the procedure. None of the patients deemed as no CC-risk at CT had CC during PPVI. CONCLUSION CT can detect patients with high and intermediate CC-risk and therefore may identify which patients are unlikely to undergo successful PPVI and those who need a careful analysis with balloon testing. CT can also rule out CC-risk identifying those patients in which balloon inflation testing could be omitted.

Abstract
BACKGROUND Transcatheter, bilateral branch pulmonary artery (PA) valve implantation is a novel treatment for patients with severe pulmonary insufficiency and oversized right ventricle (RV) outflow tract. There is scarce data on efficacy and safety of this approach. METHODS This was a retrospective study of 8 patients with repaired tetralogy of fallot (TOF) who underwent bilateral branch PA valve implantation. Demographics, echocardiography, cardiac catheterization, and axial imaging data were reviewed. Variables were compared by a paired sample t-test. RESULTS All patients were adult sized (weight 43-99 kg) with oversized RV outflow tract not suitable for conventional transcatheter pulmonary valve implantation. Staged bare metal PA stenting followed by valve implantation (interval 3-5 months) was technically successful in 7 patients with one stent embolization. In another patient, proximal stent migration prevented placement of bilateral pulmonary valve stents. There were a total of 14 valved branch PA stents placed (Melody valve n = 9, Sapien XT n = 2, Sapien 3 n = 3). In the 7 patients undergoing successful branch pulmonary valve placement, at median follow up of 10 months (range 3 months to 6 years), 13 (93%) valves had none/trivial insufficiency on echocardiography. Prevalve and postvalve implantation cardiac magnetic resonance imaging in five patients showed significant reduction of indexed RV end-diastolic volume (152 ± 27 to 105 ± 15 mL/m2 , P < .001). CONCLUSIONS Transcatheter, bilateral branch PA valve implantation was technically feasible with satisfactory efficacy and safety in patients with repaired TOF, severe pulmonary insufficiency, and oversized RV outflow tracts. Elimination of pulmonary insufficiency with this method resulted in reduced RV end-diastolic volume. This approach can be offered as an alternative to surgery, particularly in patients considered high risk for standard surgical placement and who are not candidates for the newer self-expanding valve prosthesis for placement in RV outflow tracts larger than 30 mm diameter.

Abstract
INTRODUCTION Right ventricular outflow tract (RVOT) dysfunction is a common hemodynamic challenge for adults with congenital heart disease (ACHD), including patients with repaired tetralogy of Fallot (TOF), truncus arteriosus (TA), and those who have undergone the Ross procedure for congenital aortic stenosis and the Rastelli repair for transposition of great vessels. Pulmonary valve replacement (PVR) has become one of the most common procedures performed for ACHD patients. Areas covered: Given the advances in transcatheter technology, we conducted a detailed review of the available studies addressing the indications for PVR, historical background, evolving technology, procedural aspects, and the future direction, with an emphasis on ACHD patients. Expert commentary: Transcatheter pulmonary valve implantation (TPVI) is widely accepted as an alternative to surgery to address RVOT dysfunction. However, current technology may not be able to adequately address a subset of patients with complex RVOT morphology. As the technology continues to evolve, new percutaneous valves will allow practitioners to apply the transcatheter approach in such patients. We expect that with the advancement in transcatheter technology, novel devices will be added to the TPVI armamentarium, making the transcatheter approach a feasible alternative for the majority of patients with RVOT dysfunction in the near future.

Abstract
INTRODUCTION AND OBJECTIVES A decade has passed since the first Spanish percutaneous pulmonary Melody valve implant (PPVI) in March 2007. Our objective was to analyze its results in terms of valvular function and possible mid-term follow-up complications. METHODS Spanish retrospective descriptive multicenter analysis of Melody PPVI in patients < 18 years from the first implant in March 2007 until January 1, 2016. RESULTS Nine centers were recruited with a total of 81 PPVI in 77 pediatric patients, whose median age and weight were 13.3 years (interquartile range [IQR], 9.9-15.4) and 46kg (IQR, 27-63). The predominant cardiac malformation was tetralogy of Fallot (n = 27). Most of the valves were implanted on conduits, especially bovine xenografts (n = 31). The incidence of intraprocedure and acute complications was 6% and 8%, respectively (there were no periprocedural deaths). The median follow-up time was 2.4 years (IQR, 1.1-4.9). Infective endocarditis (IE) was diagnosed in 4 patients (5.6%), of which 3 required surgical valve explant. During follow-up, the EI-related mortality rate was 1.3%. At 5 years of follow-up, 80% ± 6.9% and 83% ± 6.1% of the patients were free from reintervention and pulmonary valve replacement. CONCLUSIONS Melody PPVI was safe and effective in pediatric patients with good short- and mid-term follow-up hemodynamic results. The incidence of IE during follow-up was relatively low but was still the main complication.

Abstract
PURPOSE OF REVIEW Procedural technique and short-term outcomes of transcatheter pulmonary valve implantation (TPVI) have been widely described. The purpose of this article is to provide an update on current valve technology, and to focus on recent data surrounding TPVI in the dilated right ventricular outflow tract (RVOT), hybrid interventions, significant outcomes, and procedural costs. RECENT FINDINGS Transcatheter valve technology has expanded with current trials evaluating self-expandable valves that can be implanted in dilated RVOTs. Until those valves are widely available, hybrid techniques have been shown to offer a potential alternative in these patients, as well as in patients of small size. Although medium-term results of TPVI have shown 5-year freedom from reintervention or replacement of 76%, new data have underlined some concerns relating to bacterial endocarditis after the procedure. Procedural costs remain a concern, but vary greatly between institutions and healthcare systems. SUMMARY TPVI has emerged as one of the most innovative procedures in the treatment of patients with dysfunctional RVOT and pulmonary valves. Further device development is likely to expand the procedure to patients of smaller size and with complex, dilated RVOTs.

Abstract
Few topics in adult congenital heart disease have approached the level of scrutiny bestowed on pulmonary valve replacement (PVR) strategies late after tetralogy of Fallot (TOF) repair. Despite the successes of primary surgery for TOF, there is a growing group of adults with residual right ventricular outflow tract and pulmonary valve dysfunction. Patients with residual chronic pulmonic regurgitation as a consequence of earlier surgery can later develop symptoms of exercise intolerance and complications including heart failure, tachyarrhythmias, and sudden cardiac death. Optimal timing of PVR has sparked debate, which has catalyzed increasing research efforts over the past decade. Although performance of PVR in the absence of symptoms is currently on the basis of the rationale that achievement of complete reverse remodelling is highly desirable, whether this approach results in improvement in patient outcomes in the long-term has yet to be shown. Surgical PVR and percutaneous pulmonary valve intervention are different techniques with specific advantages and disadvantages that require careful consideration for each individual patient, alongside the need for requisite reinterventions over the course of a patient's lifetime. Criteria pertaining to referral strategies are ever being refined as newer technologies for percutaneous therapies continue to evolve. In this article we review the literature surrounding the indications for, the optimal timing of, and the approaches to pulmonary valve procedures in adults with previously repaired TOF.

Abstract
Successful outcome in the care of patients with congenital heart disease depends on a comprehensive multidisciplinary team. Surgery is offered for almost every heart defect, despite complexity. Early mortality for cardiac surgery in the neonatal period is ≈10% and beyond infancy is <5%, with 90% to 95% of patients surviving with a good quality of life into the adult years. Advances in imaging have facilitated accurate diagnosis and planning of interventions and surgical procedures. Similarly, advances in the perioperative medical management of patients, particularly with intensive care, has also contributed to improving outcomes. Arrhythmias and heart failure are the most common late complications for the majority of defects, and reoperation for valvar problems is common. Lifelong surveillance for monitoring of recurrent or residual structural heart defects, as well as periodic assessment of cardiac function and arrhythmia monitoring, is essential for all patients. The field of congenital heart surgery is poised to incorporate new innovations such as bioengineered cells and scaffolds that will iteratively move toward bioengineered patches, conduits, valves, and even whole organs.

Quantification and comparison of the mechanical properties of four human cardiac valves. Acta Biomater 2017; 54:345-355.

Abstract
OBJECTIVE Although having the same ability to permit unidirectional flow within the heart, the four main valves-the mitral valve (MV), aortic (AV), tricuspid (TV) and pulmonary (PV) valves-experience different loading conditions; thus, they exhibit different structural integrity from one another. Most research on heart valve mechanics have been conducted mainly on MV and AV or an individual valve, but none quantify and compare the mechanical and structural properties among the four valves from the same aged patient population whose death was unrelated to cardiovascular disease. METHODS A total of 114 valve leaflet samples were excised from 12 human cadavers whose death was unrelated to cardiovascular disease (70.1±3.7years old). Tissue mechanical and structural properties were characterized by planar biaxial mechanical testing and histological methods. The experimental data were then fitted with a Fung-type constitutive model. RESULTS The four valves differed substantially in thickness, degree of anisotropy, and stiffness. The leaflets of the left heart (the AV leaflets and the anterior mitral leaflets, AML) were significantly stiffer and less compliant than their counterparts in the right heart. TV leaflets were the most extensible and isotropic, while AML and AV leaflets were the least extensible and the most anisotropic. Age plays a significant role in the reduction of leaflet stiffness and extensibility with nearly straightened collagen fibers observed in the leaflet samples from elderly groups (65years and older). CONCLUSIONS Results from 114 human leaflet samples not only provided a baseline quantification of the mechanical properties of aged human cardiac valves, but also offered a better understanding of the age-dependent differences among the four valves. It is hoped that the experimental data collected and the associated constitutive models in this study can facilitate future studies of valve diseases, treatments and the development of interventional devices. STATEMENT OF SIGNIFICANCE Most research on heart valve mechanics have been conducted mainly on mitral and aortic valves or an individual valve, but none quantify and compare the mechanical and structural properties among the four valves from the same relatively healthy elderly patient population. In this study, the mechanical and microstructural properties of 114 leaflets of aortic, mitral, pulmonary and tricuspid valves from 12 human cadaver hearts were mechanically tested, analyzed and compared. Our results not only provided a baseline quantification of the mechanical properties of aged human valves, but a age range between patients (51-87years) also offers a better understanding of the age-dependent differences among the four valves. It is hoped that the obtained experimental data and associated constitutive parameters can facilitate studies of valve diseases, treatments and the development of interventional devices.

Abstract
The Melody® transcatheter pulmonary valve system was developed for placement within right ventricle-to-pulmonary artery conduits in patients with CHD for treatment of stenosis or regurgitation, providing an alternative to open-heart surgery. Abnormal systemic venous connections altering the catheter course to the right ventricle-to-pulmonary artery conduit may present a challenge to Melody® valve implantation. We present two such cases, in which the Melody® valve was successfully implanted in teenage patients with congenitally corrected transposition of the great arteries after Senning atrial switch operation. Despite the abnormal catheter course, the right ventricle-to-pulmonary artery was approachable via the right femoral vein allowing for deployment of the Melody® valve in the appropriate position. This suggests that systemic vein-to-left atrium baffles are not prohibitive of Melody® valve implantation. This is an important implication considering the substantial population of ageing patients with CHD who have undergone atrial switch. Melody® valve implantation can be considered as a viable option for treatment of these patients if they develop right ventricle-to-pulmonary artery conduit failure.

Abstract
AIMS We reviewed our center experience in the field of transcatheter pulmonary valve-in-valve implantation (TPViV), that is emerging as a treatment option for patients with pulmonary bioprosthetic valve (BPV) dysfunction. METHODS Between April 2008 and September 2015, a total of six patients with congenital heart disease (four men) underwent TPViV due to stenosis of preexisting BPV. Four patients received a Melody Medtronic Transcatheter Pulmonary Valve and two an Edward Sapien Valve. RESULTS No procedural-related complications occurred. After valve implantation, right ventricular systolic pressure (RVSP, 80.5 ± 25.3-41.2 ± 8.35 mmHg, P < 0.05), right ventricular outflow tract (RVOT) gradient (55.3 ± 23.4-10.6 ± 3.8 mmHg, P < 0.05), and RVSP-to-aortic pressure (0.75 ± 0.21-0.38 ± 0.21, P = 0.01) fell significantly. Echocardiograms at follow-up revealed a significant reduction in estimated RVSP (88.7 ± 22-21.7 ± 4.7 mmHg, P < 0.05), in RVOT (76.2 ± 17.9-25.7 ± 6.1 mmHg, P = 0.005), and in mean RVOT (40.7 ± 9.9-15.5 ± 4.8 mmHg, P < 0.05) gradients. Cardiac magnetic resonance showed no significant change in biventricular dimensions and function. Symptomatic patients reported improvement of symptoms, although cardiopulmonary exercise did not show any significant differences. CONCLUSION TPViV is an effective and well tolerated treatment for BPV dysfunction, improving freedom from surgical reintervention. Long-term studies will redefine the management of dysfunctional RVOT, either native or surrogate.
