| Summary: | Generally, the dysfunction or failure of bioprosthetic heart valves (BHVs) is managed by replacement surgery. In the case of tricuspid valve dysfunction, re-do surgery is rarely attempted because of the critically high risk of developing pulmonary hypertension, pulmonary embolism, and intraoperative mortality. Hence, transcatheter tricuspid repair and replacement procedures are preferred. More recently, transcatheter valve-in-valve (ViV) treatments have gained importance because of their less invasiveness, especially for patients with prior surgeries. Encouraging evidence of the safety and effectiveness of a novel balloon-expandable (BE) transcatheter heart valve (THV)—the Myval THV—has been reported for ViV procedures. Here, we present a case-series of 5 patients, in whom tricuspid ViV procedure was performed using BE Myval THV, implanted supra-annularly by anchoring onto the deteriorated BHV. This case-series details the procedural steps to prevent in-hospital adverse events and early (30-day) mortality and the challenges during tricuspid ViV interventions.
