A 56-year-old female who had been diagnosed with Ebstein's anomaly was admitted with cyanosis and congestive heart failure. The echocardiogram showed severe tricuspid valve incompetence, displacement of the tricuspid valve and dilatation of the atrialized portion of the right ventricle. Atrial fibrillation was detected in the electrocardiogram. She underwent tricuspid valve replacement and right atrial maze procedure. She is released from congestive heart failure and remains in sinus rhythm 48 months after the operation.

Stuck Prosthetic Valves: Clinical Implications of Pannus Formation and Gradient Measurement in Surgical Outcomes.

Department of Cardiovascular Surgery, Ankara Yıldırım Beyazıt University Faculty of Medicine, 06010 Ankara, Türkiye.
Stuck prosthetic valves, often resulting from pannus formation or thrombus accumulation, represent a critical complication in prosthetic valve management, carrying significant risks for morbidity and mortality. This study aims to identify factors associated with stuck valve development and assess the effectiveness of interventions in restoring normal valve function. A total of 27 patients with stuck valves were analyzed, including mitral, aortic, and tricuspid valve cases.

Deregulation of micro-RNAs (miRNAs) may contribute to mechanisms of injury in the bicuspid aortic valve (BAV). Our objective was to investigate the expression of miRNAs in aortic tissue from patients who underwent aortic valve replacement for aortic stenosis and its relationship with aortic dilatation. The study included 78 patients, 40 with bicuspid aortic valve (BAV) and 38 with tricuspid aortic valve (TAV).

This study sought to explore the clinical factors associated with classical low-flow low-gradient (C-LFLG) and normal-flow low-gradient (NFLG) aortic stenosis (AS) compared to high-gradient (HG) AS. We also compared clinical and echocardiographic outcomes after transcatheter aortic valve replacement (TAVR) across flow-gradient patterns. Patients with C-LFLG AS have a higher mortality rate after TAVR than those with HG AS.

Introduction: A leadless pacemaker (LLPM) was recommended for a patient with intermittent complete heart block and near-syncope.
Methods And Results: Delivery of LLPM is through a large sheath that has limited deflection and steerability. This report describes the successful deployment of a ventricular LLPM in a patient with prior surgical correction of AV septal defect with subsequent significant right atrial enlargement.
Outcomes of Suction Debulking and Surgery in Patients With Isolated Tricuspid Valve Endocarditis.

Objective: Percutaneous vegetation debulking has been reported to treat tricuspid valve infective endocarditis (TVIE), but data on feasibility compared with conventional surgical strategies are limited. We aimed to compare short-term outcomes of suction debulking with partial venovenous bypass to conventional open surgery in this population.
Methods: This was a single-center, retrospective study that included all patients with isolated TVIE who underwent suction debulking with partial venovenous bypass or tricuspid valve surgery between January 2010 and December 2022.
