Potential role of cardiopulmonary exercise testing in evaluating functional improvement after transcatheter edge-to-edge tricuspid valve repair: a case report.
European Heart Journal. Case Reports 2024 March
BACKGROUND: Tricuspid regurgitation (TR) is common and severe or greater TR is linked to poor prognosis. Treatment of TR with transcatheter edge-to-edge repair has emerged as a safe and potentially effective therapy in these patients. However, the impact of transcatheter tricuspid repair on functional capacity remains to be elucidated.
CASE SUMMARY: We describe the case of a 77-year-old woman complaining of heart failure symptoms, undergoing transcatheter edge-to-edge valve repair for severe TR with the PASCAL Ace® device. One month later, cardiopulmonary exercise testing (CPET) showed significant improvement in peak O2 uptake and O2 pulse compared with the test performed before the procedure.
DISCUSSION: A positive impact of novel transcatheter edge-to-edge valve repair on symptoms and quality of life in patients with severe or greater TR at prohibitive surgical risk has recently emerged. The presence of severe TR has prognostic relevance, and novel percutaneous tricuspid valve repair systems have emerged in the last few years. Cardiopulmonary exercise testing is an established tool to assess functional capacity and prognosis in heart failure patient. Detecting functional capacity improvement after transcatheter edge-to-edge repair for severe TR can be challenging, and CPET may arise as a promising tool to help these purposes.
