Article Abstract
Transcatheter pulmonary valve replacement (TPVR) is complicated in patients without adequate femoral or internal jugular vascular access. Transhepatic vascular access has been shown to be safe and effective across a spectrum of diagnostic and interventional procedures. Closure of the hepatic venous tract can be accomplished with a multitude of readily available vascular occlusion devices. The rates of major adverse events are low: 5% to 8% with hemoperitoneum and complete heart block are most significant. To our knowledge, this is the first report of using transhepatic access for TPVR; closure of the hepatic venous tract was achieved with an Amplatzer vascular plug type II.
Background And Objective: Dysfunction of the right ventricular outflow tract (RVOT) is a common long-term complication following surgical repair in patients with congenital heart disease. Transcatheter pulmonary valve implantation (TPVI) offers a viable alternative to surgical pulmonary valve replacement (SPVR) for treating pulmonary regurgitation but not all RVOT anatomies are suitable for TPVI. To identify a suitable landing zone (LZ) for TPVI, three-dimensional multiphase (4D) computed tomography (CT) is used to evaluate the size, shape, and dynamic behavior of the RVOT throughout the cardiac cycle.
Background: In patients with adult congenital heart disease (ACHD), significant atrioventricular valve regurgitation is an important risk factor for poor outcomes, such as heart failure. However, in many cases, transcatheter intervention may reduce the risk profile to avoid a high surgical risk.
Case Summary: A 44-year-old man with complex ACHD in the form of a double-inlet left ventricle, congenitally corrected transposition of the great arteries, pulmonary atresia, atrial septal defect, and patent ductus arteriosus was referred for the treatment of severe tricuspid regurgitation.
Background: Patients with symptomatic aortic stenosis are a vulnerable population with associated cardiac damage and a significant comorbidity burden. This study aimed to determine the rate, factors associated with, and prognostic value of poor functional status (NYHA class III-IV) in patients with severe aortic stenosis undergoing transcatheter aortic valve replacement (TAVR).
Methods: This multicenter study included 6,363 transarterial TAVR patients, classified according to baseline functional status (NYHA class I-II vs.
A circular shunt, initially described by Shone et al. in 1962, refers to abnormal blood recirculation through complete intracardiac or intra- and extracardiac communications, bypassing the capillary beds. This pathophysiological condition is most commonly associated with complex congenital heart defects, such as Ebstein's malformation, pulmonary atresia, Gerbode defect, and so on.
Background: Understanding the conduction axis location aids in avoiding iatrogenic damage and guiding targeted heart rhythm therapy.
Objective: Cardiac structures visible with clinical imaging have been demonstrated to correlate with variability in the conduction system course. We aimed to standardize and assess the reproducibility of predicting the location of the atrioventricular conduction axis by cardiac computed tomographic.
