Staged Percutaneous Management of Pulmonary Atresia and Intact Interventricular Septum: Stretching the Limits. J Interv Cardiol 2023; 2023:9709227. [PMID: 36793670 PMCID: PMC9908361 DOI: 10.1155/2023/9709227] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Revised: 09/24/2022] [Accepted: 12/12/2022] [Indexed: 02/04/2023] Open
Abstract
Aims Pulmonary atresia with intact ventricular septum (PA/IVS) can be treated by catheter-based interventions and complemented by various surgical procedures. We aim to determine a long-term treatment strategy to enable patients to be surgery free, depending solely on percutaneous interventions. Methods and Results We selected five patients from among a cohort of patients with PA/IVS treated at birth with radiofrequency perforation and dilatation of the pulmonary valve. Patients had reached a pulmonary valve annulus of 20 mm or larger on their biannual echocardiographic follow-up, with right ventricular dilatation. The findings, together with the right ventricular outflow tract and pulmonary arterial tree, were confirmed by multislice computerised tomography. Based on the angiographic size of the pulmonary valve annulus, all patients were successfully implanted with either Melody® or Edwards® pulmonary valves percutaneously, regardless of their small weights and ages. No complications were encountered. Conclusion We managed to stretch the age and weight limitations for performing percutaneous pulmonary valve implantation (PPVI): interventions were attempted whenever a pulmonary annulus size of >20 mm was reached, which was rationalised by the prevention of progressive right ventricular outflow tract dilatation and accommodating valves between 24 and 26 mm, which is enough to sustain a normal pulmonary flow in adulthood.

Catheter Cardiovasc Interv 2021; 99:E38-E42. [PMID: 34674370 DOI: 10.1002/ccd.29985] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2021] [Revised: 10/05/2021] [Accepted: 10/10/2021] [Indexed: 11/07/2022]
Abstract
Pulmonary percutaneous valve implantation (PPVI) is feasible with satisfactory mid-term results in patients with native right ventricular outflow tract (RVOT) and has been increasingly used instead of surgically implantable pulmonary valves. Creating a stable landing zone with a diameter less than the largest commercially available valve (previously available 29 mm and currently available 32 mm) is crucial for technical success of the procedure, limiting the number of suitable candidates for PPVI. We report the case of PPVI with a 32 mm Myval transcatheter heart valve in a patient with a large native RVOT (pre-stented with AndraStent XXL mounted on a 35 × 60 mm valve balloon catheter) lesion who had Tetralogy of Fallot surgically corrected. The post-procedural outcomes of this case were satisfactory with no complications reported during the hospital stay.

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.

Next-generation transcatheter aortic valve implantation. JTCVS OPEN 2020; 3:14-24. [PMID: 36003870 PMCID: PMC9390526 DOI: 10.1016/j.xjon.2020.06.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/14/2020] [Revised: 06/14/2020] [Accepted: 06/17/2020] [Indexed: 11/22/2022]
Abstract
Objective Transcatheter aortic valve implantation (TAVI) procedures are increasing rapidly, but the durability of tissue valve and periprocedural complications are not satisfactory. Immune reaction to the galactose-α-1,3 galactose β-1,4-N-acetylglucosamine (α-Gal) and conventional processing protocols of cardiac xenografts lead to calcification. Next-generation TAVI needs to be made with α-Gal–free xenografts by multiple anticalcification therapies to avoid immune rejection and enhance durability, and three-dimensional (3D) printing technology to improve the procedural safety. Methods Porcine pericardia were decellularized and immunologically modified with α-galactosidase. The pericardia were treated by space filler, crosslinked with glutaraldehyde in organic solvent, and detoxified. The sheep-specific nitinol (nickel–titanium memory alloy) wire backbone was made from a 3D-printed model for ovine aortic root. After it passed the fitting test, we manufactured a self-expandable stented valve with the porcine pericardia mounted on the customized nitinol wire–based stent. After in vitro circulation using customized silicone aortic root, we performed TAVI in 9 sheep and obtained hemodynamic, radiological, immunohistopathological, and biochemical results. Results The valve functioned well, with excellent stent fitting and good coronary flow under in vitro circulation. Sheep were sequentially scheduled to be humanely killed until 238 days after TAVI. Echocardiography and cardiac catheterization demonstrated good hemodynamic status and function of the aortic valve. The xenografts were well preserved without α-Gal immune reaction or calcification based on the immunological, radiographic, microscopic, and biochemical examinations. Conclusions We proved preclinical safety and efficacy for next-generation α-Gal–free TAVI with multiple anticalcification therapies and 3D-printing technology. A future clinical study is warranted based on these promising preclinical results.

Abstract
Percutaneous pulmonary valve implantation (PPVI) is used to treat pulmonary stenosis (PS) or pulmonary regurgitation (PR). We described our experience with PPVI, specifically valve-in-valve transcatheter pulmonary valve replacement using the Melody valve and novel self-expandable systems using the Pulsta valve. We reviewed data from 42 patients undergoing PPVI. Twenty-nine patients had Melody valves in mostly bioprosthetic valves, valved conduits, and homografts in the pulmonary position. Following Melody valve implantation, the peak right ventricle-to-pulmonary artery gradient decreased from 51.3 ± 11.5 to 16.7 ± 3.3 mmHg and right ventricular systolic pressure fell from 70.0 ± 16.8 to 41.3 ± 17.8 mmHg. Thirteen patients with native right ventricular outflow tract (RVOT) lesions and homograft underwent PPVI with the new self-expandable Pulsta valve—a nitinol wire stent mounted with a trileaflet porcine pericardial valve. Following Pulsta valve implantation, cardiac magnetic resonance imaging showed a decreased PR fraction and that the right ventricular end-diastolic volume index decreased from 166.1 ± 11.9 to 123.6 ± 12.4 mL/m2. There were no mortality, severe procedural morbidity, or valve-related complications. At the mean 14.2 month (4–57 months) follow-up, no patients had more than mild PR. PPVI using Melody and Pulsta valves was first shown to provide excellent early outcomes without serious adverse event in most patients with RVOT dysfunction in Korea.

Abstract
INTRODUCTION Right ventricular outflow tract (RVOT) dysfunction is common among individuals with congenital heart disease (CHD). Surgical intervention often carries prohibitive risks due to the need for sequential pulmonary valve (PV) replacements throughout their life in the majority of cases. Transcatheter pulmonary valve replacement (tPVR) is one of the most exciting recent developments in the treatment of CHD and has evolved to become an attractive alternative to surgery in patients with RVOT dysfunction. AREAS COVERED In this review, we examine the pathophysiology of RVOT dysfunction, indications for tPVR, and the procedural aspect. Advancements in clinical application and valve technology will also be covered. EXPERT OPINION tPVR is widely accepted as an alternative to surgery to address RVOT dysfunction, but still significant numbers of patients with complex RVOT morphology deemed not suitable for tPVR. As the technology continues to evolve, new percutaneous valves will allow such complex RVOT patient to benefit from tPVR.

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
Patients with congenital heart disease (CHD) with right ventricle outflow tract (RVOT) dysfunction need sequential pulmonary valve replacements throughout their life in the majority of cases. Since their introduction in 2000, the number of percutaneous pulmonary valve implantations (PPVI) has grown and reached over 10,000 procedures worldwide. Overall, PPVI has been proven safe and effective, but some anatomical variations can limit procedural success. This review discusses the current status and future perspectives of the procedure.

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/PURPOSE Percutaneous pulmonic valve implantation (PPVI) is an alternative treatment strategy to surgical pulmonic valve implantation (SPVI) for right ventricular outflow tract (RVOT) dysfunction. This study sought to compare outcomes of both treatment strategies. METHODS The study population was extracted from the 2014 Nationwide Readmissions Database (NRD) using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes for PPVI and SPVI. Study outcomes included all-cause in-hospital mortality, length of index hospital stay (LOS), post-procedural bleeding, mechanical complications of heart valve prosthesis, vascular complications (VC), infective endocarditis (IE), total hospitalization charges, and 30-day readmission rates. RESULTS A total of 975 patient discharges (176 in PPVI and 799 in SPVI group) were identified (average age 25.7 years; 57.5% male). PPVI was associated with significantly shorter median LOS (1 versus 5 days, p < 0.01), lower risk of bleeding (4.6% versus 26.4%, p < 0.01), and lower total hospitalization charges ($169,551.7 versus $210,681.8, p = 0.02). There was no significant difference between both groups in terms of all-cause in-hospital mortality (0% versus 1.4%, p = 0.12), mechanical complications of heart valve prosthesis (1.7% versus 2.0%, p = 0.78), VC (2.3% versus 2.0%, p = 0.82), IE (1.7% versus 3.1%, p = 0.31), or 30-day readmission rates (4.4% versus 7.6%, p = 0.16). CONCLUSION Compared with SPVI, PPVI was associated with shorter LOS, lower bleeding, and lower total charges. There was no significant difference between the two strategies in terms of all-cause in-hospital mortality, mechanical complications of heart valve prosthesis, VC, IE, or 30-day readmission rates.

Abstract
Surgical repair of tetralogy of Fallot (ToF) in childhood is associated with generally good outcomes, and almost all children can be expected to survive until adulthood. However, significant pulmonary regurgitation leading to progressive right ventricular dilatation is common in teenagers or young adults because of the nature of the surgical intervention. In patients whose repair included placement of a right ventricle to pulmonary artery conduit, it has been possible to place a stented valve within the conduit to treat this. Pulmonary regurgitation after repair of ToF via a transannular patch technique has historically involved repeat surgery as the dimensions of the right ventricular outflow tract have been too large for commercially available valves. This review summarises the novel transcatheter valves available for management of pulmonary regurgitation after surgical repair of ToF in patients in whom the dimensions of the right ventricular outflow tract have previously been considered too large for transcatheter valve implantation.

Abstract
Since 1929, when the first cardiac catheterization was safely performed in a human by Dr. Werner Forssmann (on himself), there has been a rapid progression of cardiac catheterization techniques and technologies. Today, these advances allow us to treat a wide variety of patients with congenital heart disease using minimally invasive techniques; from fetus to infants to adults, and from simple to complex congenital cardiac lesions. In this article, we will explore some of the exciting advances in cardiac catheterization for the treatment of congenital heart disease, including transcatheter valve implantation, hybrid procedures, biodegradable technologies, and magnetic resonance imaging (MRI)-guided catheterization. Additionally, we will discuss innovations in imaging in the catheterization laboratory, including 3D rotational angiography (3DRA), fusion imaging, and 3D printing, which help to make innovative interventional approaches possible.

Abstract
Congenital heart interventions are now replacing surgical palliation and correction in an evolving number of congenital heart defects. Right ventricular outflow tract and ductus arteriosus stenting have demonstrated favorable outcomes compared to surgical systemic to pulmonary artery shunting, and it is likely surgical pulmonary valve replacement will become an uncommon procedure within the next decade, mirroring current practices in the treatment of atrial septal defects. Challenges remain, including the lack of device design focused on smaller infants and the inevitable consequences of somatic growth. Increasing parental and physician expectancy has inevitably lead to higher risk interventions on smaller infants and appreciation of the consequences of these interventions on departmental outcome data needs to be considered. Registry data evaluating congenital heart interventions remain less robust than surgical registries, leading to a lack of insight into the longer-term consequences of our interventions. Increasing collaboration with surgical colleagues has not been met with necessary development of dedicated equipment for hybrid interventions aimed at minimizing the longer-term consequences of scar to the heart. Therefore, great challenges remain to ensure children and adults with congenital heart disease continue to benefit from an exponential growth in minimally invasive interventions and technology. This can only be achieved through a concerted collaborative approach from physicians, industry, academia and regulatory bodies supporting great innovators to continue the philosophy of thinking beyond the limits that has been the foundation of our specialty for the past 50 years.

Abstract
PURPOSE OF REVIEW The past couple of decades have brought tremendous advances to the field of pediatric and adult congenital heart disease (CHD). Percutaneous valve interventions are now a cornerstone of not just the congenital cardiologist treating patients with congenital heart disease, but also-and numerically more importantly-for adult interventional cardiologists treating patients with acquired heart valve disease. Transcatheter pulmonary valve replacement (tPVR) is one of the most exciting recent developments in the treatment of CHD and has evolved to become an attractive alternative to surgery in patients with right ventricular outflow tract (RVOT) dysfunction. This review aims to summarize (1) the current state of the art for tPVR, (2) the expanding indications, and (3) the technological obstacles to optimizing tPVR. RECENT FINDINGS Since its introduction in 2000, more than ten thousands tPVR procedures have been performed worldwide. Although the indications for tPVR have been adapted earlier from those accepted for surgical intervention, they remain incompletely defined. The new imaging modalities give better assessment of cardiac anatomy and function and determine candidacy for the procedure. The procedure has been shown to be feasible and safe when performed in patients who received pulmonary conduit and or bioprosthetic valves between the right ventricle and the pulmonary artery. Fewer selected patients post trans-annular patch repair for tetralogy of Fallot may also be candidates for this technology. Size restrictions of the currently available valves limit deployment in the majority of patients post trans-annular patch repair. Newer valves and techniques are being developed that may help such patients. Refinements and further developments of this procedure hold promise for the extension of this technology to other patient populations.

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.
