Abstract The majority of patients with congenitally corrected transposition of the great arteries, also known as transposition of the great arteries {S,L,L} have ventricular septal defects (VSD), most commonly perimembranous VSD (pmVSD). Transcatheter device closure of pmVSD in these patients has not been widely described. We present a case of device closure of pmVSD in L-TGA with an Amplatzer Duct Occluder II (ADOII) device using a deployment starting in the subpulmonary left ventricle. The case demonstrates some of the technical advantages of the ADOII device for VSD closure, specifically its low profile, symmetric shape, and soft More >

Abstract Background: Left atrial appendage closure (LAAC) with simultaneous interventional occlusion therapy for congenital interatrial communication has become a new focus of patients with nonvalvular atrial fibrillation. Little is known about the results of mid-and long-term results. Objective: The aim of this study was to evaluate the midand long-term safety and effectiveness of simultaneous transcatheter closure of the left atrial appendage (LAA) and congenital interatrial communication closure in atrial fibrillation (AF) patients. Methods: From Jan 2016 to June 2017, 27 patients with AF were treated with simultaneous transcatheter closure of the LAA and atrial septal defect (ASD, n… More >

Abstract Objective: This study aims to evaluate the morphology and function of the aortic valve after transcatheter closure of ventricular septal defect (VSD) with aortic valve prolapse (AVP) abased on clinical and radiological outcomes. Methods: From January 2013 to November 2014, 164 consecutive patients (97 males, 59.1%) with VSD and AVP were treated by transcatheter closure. The patients were divided into the mild AVP group (n = 63), moderate AVP group (n = 89) and severe AVP group (n = 12). The clinical and radiological outcomes of these patients were analyzed retrospectively. Results: In total, 146 (89.0%) patients… More >

Abstract Paravalvular Leakage (PVL) has been recognized as one of the most dangerous complications in relation to Transcathether Aortic Valve Implantation (TAVI) activities. However, data available in the literature about Fluid Structure Interaction (FSI) for this specific problem are relatively limited. In the present study, the fluid and structure responses of the hemodynamics along the patient aorta model and the aortic wall deformation are studied with the aid of numerical simulation taking into account PVL and 100% TAVI valve opening. In particular, the aorta without valve (AWoV) is assumed as the normal condition, whereas an aorta… More >

Abstract Objectives: We report our experience of using the 65 cm large diameter GORE^® DrySeal Flex Introducer sheath to facilitate transcatheter implantation of the Venus P-valve in the pulmonary position. Background: Transcatheter implantation of pulmonary valves can be difficult due to rigidity of the valve delivery system or the anatomy of the RVOT and pulmonary artery bifurcation and the risk of iatrogenic damage to the tricuspid valve support apparatus. Using long sheaths to pass and protect the tricuspid valve may facilitate the procedure. Methods: Multi-centre registry of patients who underwent transcatheter pulmonary valve implantation of the Venus P-valve… More >

Abstract Background: Pulmonary valve replacement (PVR) can be accomplished via surgical, transcatheter, or hybrid approaches. There are inherent advantages to transcatheter PVR and hybrid PVR without cardiopulmonary bypass. We review the methods and results of a standardized institutional approach to PVR. Methods: Retrospective review of all PVR cases between February 2017 and February 2020. Hybrid PVR entailed off-pump RVOT plication with percutaneous transcatheter PVR. Results: Primary transcatheter PVR was attempted in 37, hybrid PVR was performed in 11, and on-pump surgical PVR was performed in 9. Median age at PVR was 27 years (6–65). Primary transcatheter PVR was… More >

Abstract Objective: To evaluate the efficacy of Amplatzer duct occluder II (ADO II) in the treatment of perimembranous ventricular septal defect (pmVSD) in children. Methods: Between June 2017 and June 2020, 13 patients with pmVSD had attempted transcatheter closure using ADO II, seven of patients were used antegrade approach and six of them were used retrograde approach. Results: There were 8 males and 5 females, age from 1 to 7 years, weight from 10.5 to 31.0 kg, and VSD size from 2.0 to 4.0 mm. Procedure was successful in all cases with the outer diameter of the occluders More >

Abstract Background: Communication between the right pulmonary artery (RPA) and left atrium (LA) is a rare cause of central cyanosis in pediatric patients. Case presentation: We describe a 3-year-old female patient with an oxygen saturation of 70% at admission. The echocardiogram indicated an abnormal color flow Doppler in the LA and she underwent standard cardiac catheterization. The angiography of pulmonary artery revealed a 7.4 mm × 7.6 mm fistula between the RPA and LA and achieved successful closure using ventricular septal defect occlusion. Conclusion: The fistula between pulmonary artery and left atrium is an extremely rare but treatable More >

Abstract Marfan syndrome patients have connective tissue abnormalities that predispose them to intracardiac defects and postoperative complications. We present a case of late onset ASD device failure secondary to device movement within the atrial septum in a girl with Marfan syndrome. This case study suggests that further studies are necessary to determine the optimal device and approach for ASD repair in this patient cohort. More >

Abstract Background: Trans-catheter closure has become the treatment of choice for patent foramen ovale (PFO) and ostium secundum atrial septal defects (ASD). A wide variety of devices are commercially available, however, concerns have been raised about the risk of cardiac erosion associated with stiff/rigid devices. The GORE® CARDIOFORM Septal Occluder (GSO) is a double-disc, soft and conformable device with no reported incidence of cardiac erosions. However, wire frame fracture (WFF) have been reported. Aim: To assess the incidence and clinical significance of WFF after GSO implantation in paediatric patients. Methods: Seventy-seven consecutive patients were enrolled. Periprocedural and follow-up… More >
