One-year outcomes following successful transseptal balloon-expandable transcatheter heart valve implantation in high-risk patients with degenerated mitral bioprostheses are excellent, characterized by durable symptom relief and prosthesis function. Although mitral valve in ring and valve in MAC have higher operative morbidity and mortality, 1-year outcomes after an initially successful procedure are favorable in carefully selected patients.

Perioperative myocardial infarction is an important complication of ligation of coronary artery fistulas and can contribute to reduced late survival. The tricuspid valve should be evaluated carefully at repair because of the relatively high rate of residual regurgitation in survivors.

Cone repair is safe, and the learning curve is significant. Sustained reduction in tricuspid regurgitation and favorable changes in the right ventricle at follow-up suggest that cone repair has an advantageous impact on right ventricular remodeling.

In contemporary practice, patients with symptomatic mitral PVLs are best treated with an integrated team approach incorporating both surgical and percutaneous techniques. Patient selection and timing of intervention are critical to achieve optimal results.
