Introduction: The advancement of medical technology has introduced leadless pacemakers (LPMs) as a significant innovation in cardiac pacing, offering potential advantages over traditional ventricular transvenous pacemakers. This report explores the application of LPMs in two patients with complex valvular histories, particularly those with mechanical tricuspid valves.
Case Reports: The first case involves a 60-year-old male with a history of rheumatic heart disease and triple valve replacement who developed a high-grade AV block.

Rheumatic heart disease (RHD) affecting all four valves of the heart is extremely rare. We report quadrivalvular involvement in an early adolescent male patient. The patient presented with symptomatic severe mitral and tricuspid stenosis that underscores the rapid and fulminant nature of the disease and can still be seen in developing countries.

This study reports the challenges of rheumatic mitral and tricuspid valve re-repair on a child presenting with gross hematuria, hemolysis, and volume overload. Severe postoperative mitral and tricuspid valve regurgitation was the cause, and redo surgery for both valves resolved the acute issues.

Article Synopsis
- This study aimed to explore the characteristics, causes, and patterns of patients with moderate to severe valvular heart disease (VHD) using data from Southwest Hospital between 2001 and 2020.
- A total of 68,354 patients were analyzed, revealing an average age of 63 years, with 52.24% being female; age patterns showed a peak incidence in the 65-69 age group.
- The analysis indicated differences in gender distribution for specific VHD types, with female patients showing higher rates of certain conditions, and rheumatic VHD represented a higher percentage than degenerative VHD among the patients studied.

Article Synopsis
- The study investigates the impact of severe pulmonary hypertension and low TAPSE values on the early mortality and morbidity of patients undergoing mitral valve replacement due to rheumatic conditions.
- It analyzes data from 79 patients, finding significant differences in outcomes (e.g., tricuspid regurgitation and mortality rates) between those with high pulmonary artery pressure (PAP ≥ 50) compared to those with lower levels.
- The authors suggest that timely surgical intervention could improve survival rates in patients with mitral valve issues before pulmonary pressure increases and right ventricular function worsens.
