Multicenter Experience for Early and Mid-Term Outcome of MyVal Transcatheter Pulmonary Valve Implantation. Pediatr Cardiol 2024; 45:570-579. [PMID: 38296854 DOI: 10.1007/s00246-023-03398-1] [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: 11/20/2023] [Accepted: 12/26/2023] [Indexed: 02/02/2024]
Abstract
Transcatheter pulmonary valve implantation (TPVI) is a surgical alternative for correcting dysfunctional right ventricular outflow tract in previously operated patients. MyVal transcatheter heart valve (THV) (Meril Life Sciences, India), a new transcatheter valve designed for aortic position has recently been reported to be implanted in pulmonary position. Myval transcatheter valve were implanted in patients with stenosed dysfunctional conduits, severe regurgitation from transannular patch or dysfunctional surgical pulmonary valves (Bioprosthesis). Procedural details and post-TPVI follow-up were analysed. Myval TPVI was used in Fifty three patients with median age of 15 years (IQR 12-19.5 years). Almost sixty percent of the patients were male, with a median weight of 50 kg (31-63 kg). Prestenting was used in more than 80 percent of patients (n = 45 patients), while 6 patients had a prior surgical valve implantation. After Myval TPVI implantation, the peak instantaneous gradient across the RVOT decreased from a median of 23.5 mmHg (IQR 10-53 mmHg) pre-procedure to 10 mmHg (IQR 5-16 mmHg) post-procedure. The median fluoroscopy time for the procedure was 35 min (IQR 23.5-44 min). The large sizes-mainly the 29-mm and 32 mm Myval (Navigator, Meril Life Sciences Pvt Ltd, India), were the most used size in 40% (n = 22) of the cases each. The median contrast volume used during the procedure was 247 mL (IQR 120-300 mL). Patients were followed for a median period of 360 days (IQR 164-525 days). At the last clinic follow-up, there was no tricuspid valve regurgitation. Moderate neo-pulmonary valve regurgitation was reported in three cases. Early experience of TPVI with MyVal is encouraging with procedural success in all patients and acceptable mid-term outcomes.

2024 Statement from Asia expert operators on transcatheter pulmonary valve replacement. Catheter Cardiovasc Interv 2024; 103:660-669. [PMID: 38419402 DOI: 10.1002/ccd.30978] [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: 09/14/2023] [Revised: 11/13/2023] [Accepted: 02/06/2024] [Indexed: 03/02/2024]
Abstract
Transcatheter pulmonary valve replacement (TPVR), also known as percutaneous pulmonary valve implantation, refers to a minimally invasive technique that replaces the pulmonary valve by delivering an artificial pulmonary prosthesis through a catheter into the diseased pulmonary valve under the guidance of X-ray and/or echocardiogram while the heart is still beating not arrested. In recent years, TPVR has achieved remarkable progress in device development, evidence-based medicine proof and clinical experience. To update the knowledge of TPVR in a timely fashion, and according to the latest research and further facilitate the standardized and healthy development of TPVR in Asia, we have updated this consensus statement. After systematical review of the relevant literature with an in-depth analysis of eight main issues, we finally established eight core viewpoints, including indication recommendation, device selection, perioperative evaluation, procedure precautions, and prevention and treatment of complications.

Abstract
Various transcatheter interventions for the right ventricular outflow tract (RVOT) have been introduced and developed in recent decades. Transcatheter pulmonary valve perforation was first introduced in the 1990s. Radiofrequency wire perforation has been the approach of choice for membranous pulmonary atresia in newborns, with high success rates, although complication rates remain relatively common. Stenting of the RVOT is a novel palliative treatment that may improve hemodynamics in neonatal patients with reduced pulmonary blood flow and RVOT obstruction. Whether this option is superior to other surgical palliative strategies or early primary repair of tetralogy of Fallot remains unclear. Transcatheter pulmonary valve replacement has been one of the biggest innovations in the last two decades. With the success of the Melody and SAPIEN valves, this technique has evolved into the gold standard therapy for RVOT abnormalities with excellent procedural safety and efficacy. Challenges remain in managing the wide heterogeneity of postoperative lesions seen in RVOT, and various technical modifications, such as pre-stenting, valve ring modification, or development of self-expanding systems, have been made. Recent large studies have revealed outcomes comparable to those of surgery, with less morbidity. Further experience and multicenter studies and registries to compare the outcomes of various strategies are necessary, with the ultimate goal of a single-step, minimally invasive approach offering the best longer-term anatomical and physiological results.

Transcatheter closure of perimembranous ventricular septal defect using a novel fully bioabsorbable occluder: multicenter randomized controlled trial. Sci Bull (Beijing) 2023; 68:1051-1059. [PMID: 37179234 DOI: 10.1016/j.scib.2023.04.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Revised: 03/21/2023] [Accepted: 04/14/2023] [Indexed: 05/15/2023]
Abstract
Although the use of bioabsorbable occluder is expected to reduce the risk of metal occluder-related complications, it has not been approved due to incomplete degradation and new complications. Novel fully bioabsorbable occluders were designed to overcome such limitations. The aim of this study was to investigate the efficacy and safety of a fully biodegradable occluder in patients with ventricular septal defects. 125 patients with perimembranous ventricular septal defect (VSD) larger than 3 mm were screened from April 2019 to January 2020 in seven centers. 108 patients were enrolled and randomized into the bioabsorbable occluder group (n = 54 patients) and nitinol occluder group (n = 54). A non-inferiority design was utilized and all patients underwent transcatheter device occlusion. Outcomes were analyzed with a 24-month follow-up. All patients were successfully implanted and completed the trial. No residual shunt >2 mm was observed during follow-up. Transthoracic echocardiography showed a hyperechoic area corresponding to the bioabsorbable occluder which decreased primarily during the first year after implantation and disappeared within 24 months. Postprocedural arrhythmia was the only occluder-related complication with an incidence of 5.56% and 14.81% for the bioabsorbable and nitinol groups, respectively (P = 0.112). The incidence of sustained conduction block was lower in the bioabsorbable occluder group (0/54 vs. 6/54, P = 0.036) at 24-month follow-up. In conclusion, the novel fully bioabsorbable occluder can be successfully and safely implanted under echocardiography guidance and reduce the incidence of sustained postprocedural arrythmia. The efficacy and safety of this fully biodegradable occluder are non-inferior to that of a traditional nitinol one.

Abstract
INTRODUCTION With the advent of improved neonatal care, increasingly vulnerable higher-risk patients with complex congenital heart anomalies are presenting for intervention. This group of patients will always have a higher risk of an adverse event during a procedure but by recognising this risk and with the introduction risk scoring systems and thus the development of novel lower risk procedures, the rate of adverse events can be reduced. AREA COVERED This article reviews risk scoring systems for congenital catheterization and demonstrates how they can be used to reduce the rate of adverse events. Then novel low risk strategies are discussed for low weight infants e.g. patent ductus arteriosus (PDA) stent insertion; premature infants e.g. PDA device closure; and transcatheter pulmonary valve replacement. Finally, how risk is assessed and managed within the inherent bias of an institution is discussed. EXPERT OPINION There has been a remarkable improvement in the rate of adverse events in congenital cardiac interventions but now, as the benchmark of mortality rate is switched to morbidity and quality of life, continued innovation into lower risk strategies and understanding inherent bias when assessing risk will be key to continuing this improvement.

Novel technique for transcatheter closure of sinus venosus atrial septal defect: The temporary suture-holding technique. Catheter Cardiovasc Interv 2022; 100:1068-1077. [PMID: 36183408 DOI: 10.1002/ccd.30415] [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: 02/20/2022] [Revised: 09/07/2022] [Accepted: 09/11/2022] [Indexed: 11/08/2022]
Abstract
BACKGROUND Transcatheter repair of sinus venosus atrial septal defect (SVASD) has become an alternative option to surgical repair. There are potential significant complications related to stent stability in the superior vena cava (SVC) and potential migration of the stent that need to be addressed. Therefore, the technique is still evolving. OBJECTIVES To report results of a new modification "the suture technique" that improves safety profile of positioning and securing a covered stent in the SVC. METHODS This is a descriptive, single center, retrospective review of patients who underwent SVASD closure using the suture technique at our institution between 02/2020 and 08/2022. RESULTS Fourteen patients underwent transcatheter repair of SVASD using the suture technique. All procedures were successful. The suture technique allowed precise stent placement in all patients without any migration or complication. Six patients required additional stent placement at the level of the SVC. One patient had an additional covered stent placed to eliminate a tiny residual shunt. Two patients had negligible residual shunts at the time of the procedure. At follow-up, all patients clinically improved and had significant reduction in right heart size on echocardiography and/or magnetic resonance imaging. No arrhythmia was reported in any patient. None required re-intervention after a mean follow-up of 16.5 ± SD 10.5 months. CONCLUSIONS The suture technique appears to be safe modification. Although our study involves small sample size with no comparative group, we believe our technique offers greater control over stent positioning, reducing the risk of stent embolization and residual shunting in transcatheter closure of SVASD.

Abstract
Congenital heart defects (CHDs) affect a wide range of societies with an incidence rate of 1.0–1.2%. These defects initiate at the early developmental stage and result in critical health disorders. Although genetic factors play a role in the formation of CHDs, the occurrence of cases in families with no history of CHDs suggests that mechanobiological forces may also play a role in the initiation and progression of CHDs. Hypoplastic left heart syndrome (HLHS) is a critical CHD, which is responsible for 25–40% of all prenatal cardiac deaths. The comparison of healthy and HLHS hearts helps in understanding the main hemodynamic differences related to HLHS. Echocardiography is the most common imaging modality utilized for fetal cardiac assessment. In this study, we utilized echocardiographic images to compare healthy and HLHS human fetal hearts for determining the differences in terms of heart chamber dimensions, valvular flow rates, and hemodynamics. The cross-sectional areas of chamber dimensions are determined from 2D b-mode ultrasound images. Valvular flow rates are measured via Doppler echocardiography, and hemodynamic quantifications are performed with the use of computational fluid dynamics (CFD) simulations. The obtained results indicate that cross-sectional areas of the left and right sides of the heart are similar for healthy fetuses during gestational development. The left side of HLHS heart is underdeveloped, and as a result, the hemodynamic parameters such as flow velocity, pressure, and wall shear stress (WSS) are significantly altered compared to those of healthy hearts.

Abstract
Propionic acidemia is a rare autosomal recessive inborn error of metabolism. It is relatively common in Middle East. Dilated cardiomyopathy is one of the leading causes of morbidity and mortality for patients with propionic acidemia. Liver transplantation has been used for patient with frequent metabolic decompensations and was shown to be beneficial in propionic acidemia-related dilated cardiomyopathy. Up to our knowledge, there has been one reported case of recurrent dilated cardiomyopathy 3 years after liver transplantation. We report the first case, from Middle East, of recurrent dilated cardiomyopathy, 6 years after liver transplantation.

Abstract
Introduction: Cardiac defects that result in shunting are the most common types of congenital heart anomalies. Although these lesions can be simple, they can cause significant hemodynamic changes and can be challenging to manage in neonates and infants. Over the recent decades, the development of new transcatheter techniques and devices has made it safe and feasible to manage such defects when indicated, even in the smallest of patients. Understanding these interventional procedures is essential in order to manage those patients.Areas covered: In this article, we review the techniques and experience for closure of atrial septal defects, ventricular septal defects, patent ductus aarteriosus,as well as coronary arteriovenous malformations and fistulas in neonates and infants. Literature review of PubMed articles was performed through January 2021, with focus on the latest data and results of the usage of interventional techniques in treating these lesions specifically in this age-group.Expert opinion: Significant shunting lesions can be particularly challenging to manage in neonates and infants. Newer lower profile devices will likely continue to be developed in the future, allowing their use for transcatheter interventions in even smaller patients and those with more complex anatomy.

Abstract
BACKGROUND Covered stent correction of sinus venosus ASDs (SVASD) is a relatively new technique. Challenges include anchoring a sufficiently long stent in a nonstenotic superior vena cava (SVC) and expanding the stent at the wider SVC-RA junction without obstructing the anomalous right upper pulmonary vein (RUPV). The 10-zig covered Cheatham-platinum (CCP) stent has the advantage of being available in lengths of 5-11 cm and dilatable to 34 mm in diameter. METHODS An international registry reviewed the outcomes of 10-zig CCP stents in 75 patients aged 11.4-75.9 years (median 45.4) from March 2016. Additional stents were used to anchor the stent in the SVC or close residual shunts in 33/75. An additional stent was placed in 4/5 (80%) with 5/5.5 cm CCPs, 18/29 (62%) with 6 cm CCPs, 5/18 (28%) with 7 cm CCPs, 5/22 (23%) with 7.5/8 cm CCPs and 0/1 with an 11 cm CCP. A "protective" balloon catheter was inflated in the RUPV in 17. RESULTS Early stent embolization in two patients required surgical removal and defect repair and tamponade was drained in one patient. The CT at 3 months showed occlusion of the RUPV in one patient. Follow up is from 2 months to 5.1 years (median 1.8 years). QP:QS has reduced from 2.5 ± 0.5 to 1.2 ± 0.36 (p < .001) and RVEDVi from 149.1 ± 35.4 to 95.6 ± 21.43 ml/m2 (p < .001). CONCLUSIONS Ten-zig CCPs of 7-8 cm appear to provide reliable SVASD closure with a low requirement for additional stents. Careful selection of patients and meticulous attention to detail is required to avoid complications.

Abstract
Importance Recent epidemiologic and therapeutic advances have transformed understanding of the role of and therapeutic approach to patent foramen ovale (PFO) in ischemic stroke. Patent foramen ovale is likely responsible for approximately 5% of all ischemic strokes and 10% of those occurring in young and middle-aged adults. Observations Randomized clinical trials have demonstrated that, to prevent recurrent ischemic stroke in patients with PFO and an otherwise-cryptogenic index ischemic stroke, PFO closure is superior to antiplatelet medical therapy alone; these trials have provided some evidence that, among medical therapy options, anticoagulants may be more effective than antiplatelet agents. Conclusions and Relevance These new data indicate a need to update classification schemes of causative mechanisms in stroke, developed in an era in which an association between PFO and stroke was viewed as uncertain. We propose a revised general nomenclature and classification framework for PFO-associated stroke and detailed revisions for the 3 major stroke subtyping algorithms in wide use.

Abstract
INTRODUCTION Atrial septal defect (ASD) is one of the most common congenital heart diseases (CHD) in children and adults. This group of malformations includes several types of atrial communications allowing shunting of blood between the systemic and the pulmonary circulations. Early diagnosis and treatment carries favorable outcomes. Patients diagnosed during adulthood often present with complications related to longstanding volume overload such as pulmonary artery hypertension (PAH), atrial dysrhythmias, and right (RV) and left (LV) ventricular dysfunction. AREA COVERED This article intended to review all aspects of ASD; anatomy, pathophysiology, clinical presentation, natural history, and indication for treatment. Also, we covered the transcatheter therapy in detail, including the procedural aspect, available devices, and outcomes. EXPERT OPINION There has been a remarkable improvement in the treatment strategy of ASD over the last few decades. Transcatheter closure of ASD is currently accepted as the treatment of choice in most patients with appropriately selected secundum ASDs. This review will focus on the most recent advances in diagnosis and treatment strategy of secundum ASD.

Abstract
BACKGROUND Polymer-based bioresorbable scaffolds (PBBS) have been assessed for coronary revascularization with mixed outcomes. Few studies have targeted pediatric-specific scaffolds. We sought to assess safety, efficacy, and short-term performance of a dedicated drug-free PBBS pediatric scaffold compared to a standard low-profile bare metal stent (BMS) in central and peripheral arteries of weaned piglets. METHODS Forty-two devices (22 Elixir poly-L-lactic-acid-based pediatric bioresorbable scaffolds [BRS] [6 × 18 mm] and 20 control BMS Cook Formula 418 [6 × 20 mm]) were implanted in the descending aorta and pulmonary arteries (PAs) of 14 female Yucatan piglets. Quantitative measurements were collected on the day of device deployment and 30 and 90 days postimplantation to compare device patency and integrity. RESULTS The BRS has a comparable safety profile to the BMS in the acute setting. Late lumen loss (LLL) and percent diameter stenosis (%DS) were not significantly different between BRS and BMS in the PA at 30 days. LLL and %DS were greater for BRS versus BMS in the aorta at 30 days postimplantation (LLL difference: 0.96 ± 0.26; %DS difference: 16.15 ± 4.51; p < .05). At 90 days, %DS in the aortic BRS was less, and PA BRS LLL was also less than BMS. Histomorphometric data showed greater intimal proliferation and area stenosis in the BRS at all time points and in all vessels. CONCLUSIONS A dedicated PBBS pediatric BRS has a favorable safety profile in the acute/subacute setting and demonstrates characteristics that are consistent with adult BRSs.

3-Year Outcomes of the Edwards SAPIEN Transcatheter Heart Valve for Conduit Failure in the Pulmonary Position From the COMPASSION Multicenter Clinical Trial. JACC Cardiovasc Interv 2019; 11:1920-1929. [PMID: 30286853 DOI: 10.1016/j.jcin.2018.06.001] [Citation(s) in RCA: 59] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2018] [Revised: 05/30/2018] [Accepted: 06/04/2018] [Indexed: 02/07/2023]
Abstract
OBJECTIVES This study provides the 3-year follow-up results of the COMPASSION (Congenital Multicenter Trial of Pulmonic Valve Regurgitation Studying the SAPIEN Transcatheter Heart Valve) trial. Patients with moderate to severe pulmonary regurgitation and/or right ventricular outflow tract conduit obstruction were implanted with the SAPIEN transcatheter heart valve (THV). BACKGROUND Early safety and efficacy of the Edwards SAPIEN THV in the pulmonary position have been established through a multicenter clinical trial. METHODS Eligible patients were included if body weight was >35 kg and in situ conduit diameter was ≥16 and ≤24 mm. Adverse events were adjudicated by an independent clinical events committee. Three-year clinical and echocardiographic outcomes were evaluated in these patients. RESULTS Fifty-seven of the 63 eligible patients were accounted for at the 3-year follow-up visit from a total of 69 implantations in 81 enrolled patients. THV implantation was indicated for pulmonary stenosis (7.6%), regurgitation (12.7%), or both (79.7%). Twenty-two patients (27.8%) underwent implantation of 26-mm valves, and 47 patients received 23-mm valves. Functional improvement in New York Heart Association functional class was observed in 93.5% of patients. Mean peak conduit gradient decreased from 37.5 ± 25.4 to 17.8 ± 12.4 mm Hg (p < 0.001), and mean right ventricular systolic pressure decreased from 59.6 ± 17.7 to 42.9 ± 13.4 mm Hg (p < 0.001). Pulmonary regurgitation was mild or less in 91.1% of patients. Freedom from all-cause mortality at 3 years was 98.4%. Freedom from reintervention was 93.7% and from endocarditis was 97.1% at 3 years. There were no observed stent fractures. CONCLUSIONS Transcatheter pulmonary valve replacement using the Edwards SAPIEN THV demonstrates excellent valve function and clinical outcomes at 3-year follow-up.

Abstract
Coarctation of the aorta (CoA) is a common form of congenital heart disease. Adult patients with CoA may be asymptomatic or may present with hypertension. Over the last few years, endovascular management of adult patients with CoA emerged as the preferred strategy. Stent implantation, though technically challenging, offers the best and most lasting therapy. In this paper, we will review technical considerations and outcome of patients undergoing stent implantation for CoA.

Abstract
Congenital heart disease (CHD) is the most common birth defect, occurring in approximately 0.8% to 1.0% of neonates. Advances in medical and surgical therapies for children with CHD have resulted in a growing population of patients reaching adulthood, with survival rates exceeding 85%. Many of these patients, especially if managed inappropriately, face the prospect of future complications including heart failure and premature death. For adults with uncorrected or previously palliated CHD, percutaneous therapies have become the primary treatment for many forms of CHD. In this article, we discuss the role of transcatheter interventions in the treatment of adults with CHD.

Abstract
We present a rare case of unroofed coronary sinus in a patient who underwent supra-annular tricuspid valve replacement with consequent drainage of the coronary sinus to the right ventricle. It is unclear whether the coronary sinus was unroofed congenitally or iatrogenically. This rare setup resulted in significant cyanosis. The abnormal drainage was successfully closed via trans-catheter delivery of covered stents with resolution of the cyanosis. © 2017 Wiley Periodicals, Inc.

Abstract
We report stenting of coarctation of an angulated right circumflex aortic arch (RCAA) using four Cheatham Platinum stents in a child with Goldenhar syndrome. Difficulties in measuring the accurate length of the curved and narrowed transverse aortic arch marked discrepancy between the luminal diameters of the long narrow transverse arch and wide descending thoracic aorta, increased displacement force caused by the 90° bend between the two parts resulted in repeated stent migrations. We discuss the tips to avoid distal stent migration in the setting of an angulated RCAA.

Abstract
Percutaneous therapies for congenital heart disease have evolved rapidly in the past 3 decades. This has occurred despite limited investment from industry and support from regulatory bodies resulting in a lack of specific device development. Indeed, many devices remain off-label with a best-fit approach often required, spurning an innovative culture within the subspecialty, which had arguably laid the foundation for many of the current and evolving structural heart interventions. Challenges remain, not least encouraging device design focused on smaller infants and the inevitable consequences of somatic growth. Data collection tools are emerging but remain behind adult cardiology and cardiac surgery and leading to partial blindness as to the longer-term consequences of our interventions. Tail coating on the back of developments in other fields of adult intervention will soon fail to meet the expanding needs for more precise interventions and biological materials. Increasing collaboration with surgical colleagues will require 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 that 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
CONTEXT Patent ductus arteriosus (PDA) is a precursor to morbidity and mortality. Percutaneous (catheter-based) closure is the procedure of choice for adults and older children with a PDA, but use during infancy (<1 year) is not well characterized. OBJECTIVE Investigate the technical success and safety of percutaneous PDA closure during infancy. DATA SOURCES Scopus, Web of Science, Embase, PubMed, and Ovid (Medline) were searched through December 2015 with no language restrictions. STUDY SELECTION Publications needed to clearly define the intervention as percutaneous PDA closure during infancy (<1 year of age at intervention) and must have reported adverse events (AEs). DATA EXTRACTION The study was performed according to the Systematic Reviews and Meta-Analysis checklist and registered prospectively. The quality of the selected studies was critically examined. Data extraction and assignment of AE attributability and severity were independently performed by multiple observers. Outcomes were agreed on a priori. Data were pooled by using a random-effects model. RESULTS Thirty-eight studies were included; no randomized controlled trials were found. Technical success of percutaneous PDA closure was 92.2% (95% confidence interval [CI] 88.8-95.0). Overall AE and clinically significant AE incidence was 23.3% (95% CI 16.5-30.8) and 10.1% (95% CI 7.8-12.5), respectively. Significant heterogeneity and publication bias were observed. LIMITATIONS Limitations include lack of comparative studies, lack of standardized AE reporting strategy, and significant heterogeneity in reporting. CONCLUSIONS Percutaneous PDA closure during infancy is feasible and associated with few catastrophic AEs; however, the limitations constrain the interpretability and generalizability of the current findings.

Abstract
About 10%-15% of patients with an atrial septal defect will have some form of anomalous pulmonary venous connection. With the advent of percutaneous closure of atrial septal defects, it is imperative that presence of partial anomalous pulmonary venous return be excluded to prevent unnecessary percutaneous closure in patients who would ultimately require a surgical approach. The authors herein report a 29-year-old man who underwent percutaneous closure of 2 atrial septal defects but was later found to have his left upper pulmonary vein draining into the innominate vein via a vertical vein. He subsequently underwent surgical repair of the anomalous pulmonary vein.

Abstract
Chronic mitral regurgitation (MR) is the most common cardiac valvular disease with more than 4 million people in the United States alone suffering from moderate or severe MR. Left untreated, chronic MR results in serious consequences. Surgical correction with mitral valve repair or replacement remains the mainstay of therapy for MR. Nevertheless, a large proportion of patients may not be offered treatment due to concerns over surgical risk. This unmet therapeutic need for a less invasive approach led to a marked explosion in the development of a variety of transcatheter approaches to treat mitral regurgitation in the past decade. The majority of these devices are based on principles learned from surgical mitral valve repair techniques. Inspired by the Alfieri surgical technique, the MitraClip edge-to-edge repair system is the most advanced technique with the highest safety and efficacy to date. In this review, we discuss the current status of the MitraClip repair system in the treatment of mitral regurgitation.

Abstract
A variety of therapies are available to close ventricular septal defects (VSDs). These include surgical closure on bypass, percutaneous device closure, as well as perventricular hybrid closure. Due to the incidence of heart block (1-5%) associated with percutaneous device closure of perimembranous VSDs, surgical closure presently remains the gold standard and preferred therapy for these defects. Therapeutic options are more varied for muscular VSDs. Beyond infancy, transcatheter closure offers excellent results with low morbidity and mortality, without the need for cardiopulmonary bypass. Infants however have a higher incidence of adverse events using a percutaneous approach. Large mid-muscular VSDs in infants can be treated successfully using a hybrid approach, surgical closure on bypass or a percutaneous approach. However, VSDs located apically or anteriorly are difficult to identify surgically and for these infants, perventricular hybrid closure should be considered as the preferred therapeutic modality. However, some VSD's also can be closed percutaneously.

Abstract
Patent foramen ovale (PFO) is a common finding in healthy adults and has long been implicated in cryptogenic stroke. The pathogenesis is hypothesized to be caused by microemboli gaining access into the systemic circulation via a PFO. Proposed treatment options include medical therapy and/or PFO closure. Despite numerous studies and several randomized trials, much debate persists regarding the efficacy of this approach in reducing the risk of recurrent stroke in cryptogenic stroke patients. This article reviews the association between PFO and cryptogenic stroke, as well as current evidence for PFO device closure.

Abstract
Coarctation of the aorta (C) is the sixth most common lesion in congenital heart disease and represents a spectrum of aortic narrowing that varies from a discrete entity to tubular hypoplasia. This condition was once thought to be a relatively simple lesion that would be "cured" upon repair of the narrowing, however, despite relief of the anatomical obstruction the subsequent risk of early morbidity and death persists. This review outlines the optimal management strategy of this disease from neonatal to adult life and provides insights to approach this straightforward but challenging condition.
