Article Abstract
We report a 4-month-old, 3.7-kg girl with asplenia, single ventricle physiology, a common atrioventricular valve, and severe regurgitation after repair, along with moderately depressed ventricular function. She underwent supra-annular valve replacement with a 16-mm mechanical prosthesis and 18-mm expanded polytetrafluoroethylene graft, preserving the entire valve leaflets and subvalvular apparatus. Postoperative imaging showed no inflow/outflow obstruction and preserved ventricular function. She subsequently underwent a bidirectional Glenn shunt and is currently awaiting the Fontan procedure. This approach may be a valuable surgical option in similar infants with atrioventricular valve regurgitation and ventricular dysfunction.

Despite continued advancements in transcatheter aortic valve implantation (TAVI) techniques, the incidence of permanent pacemaker implantation (PPI) remains substantial. Established predictors of PPI include advanced age, pre-existing electrocardiographic conduction abnormalities, prosthetic valve type, implantation depth, and anatomical parameters, such as membranous septum length, which are currently under active investigation. In routine clinical practice, the management strategy often involves the temporary placement of a transvenous pacemaker lead, followed by a period of observation.

Objective: Patients with heterotaxy-associated congenital heart disease often require multiple operations, which may have a cumulative effect on their outcomes. This study aimed to define the cardiac surgical course in a large cohort and identify longitudinal risk factors for death/transplant.
Methods: All patients with heterotaxy-associated congenital heart disease who underwent cardiac surgery at one institution from 2005 to 2022 were retrospectively reviewed.

Severe, untreated tricuspid regurgitation is associated with worse clinical outcomes. While isolated tricuspid valve (TV) surgery has been linked to poor long-term outcomes, transcatheter TV therapies, including edge-to-edge repair and transcatheter tricuspid valve replacement (TTVR), have emerged as effective alternatives and have been shown to improve outcomes, leading to their regulatory approval in the United States. Conduction system abnormalities are commonly seen among patients undergoing TTVR due to the close proximity of the atrioventricular node and the His bundle to the TV annulus.

Background: A high burden of right ventricular pacing (RVP) increases the risk of hospitalization because of heart failure. Data on predictive factors for high burden of RVP in patients with permanent pacemaker implantation (PPI) after transcatheter aortic valve replacement (TAVR) are limited.
Objective: This study aimed to identify predictors of high RVP burden in patients with current indications for PPI after TAVR.
