# Paravalvular Leak Closure After Transcatheter Tricuspid Valve-in-Ring Implantation: A Case Report

## TL;DR

A patient with severe tricuspid regurgitation underwent a transcatheter valve implantation followed by a minimally invasive leak closure, resulting in significant symptom improvement.

## Contribution

This case report demonstrates the successful use of a dedicated PVL closure device after transcatheter tricuspid valve-in-ring implantation.

## Key findings

- The patient experienced trivial tricuspid regurgitation after PVL closure.
- Significant clinical improvement was observed following the procedure.

## Abstract

Transcatheter tricuspid valve intervention (TTVI) has emerged as a promising alternative for patients with severe tricuspid regurgitation who are deemed high-risk for surgery. With advancements in device design and delivery systems, TTVI has shown promising outcomes in reducing tricuspid regurgitation severity and improving symptoms in selected patients. Paravalvular leaks (PVLs) are one of the most common complications faced, which can significantly contribute to patients’ morbidity and mortality. Percutaneous PVL closure represents a minimally invasive approach to address this issue, but its efficacy and safety in the context of transcatheter tricuspid valve-in-ring implantation require further elucidation.

We describe the case of a 44-year-old lady with a history of rheumatic valve disease status post-tricuspid valve annuloplasty with an incomplete ring who presented to cardiology clinics with symptomatic torrential tricuspid regurgitation. Due to the high risk of surgical reintervention secondary to severe right ventricular (RV) failure, she was denied surgical intervention. Therefore, she underwent transcatheter tricuspid valve-in-ring (TVIR) implantation with a 26 mm MyVal (Meril Life Sciences Pvt Ltd., Vapi, GJ, IND), which was complicated by a residual severe tricuspid paravalvular regurgitation. The defect was subsequently closed by a dedicated Occlutech PVL device (Occlutech, Helsingborg, SWE) measuring 18 mm x 10 mm. Post which, the patient had trivial tricuspid regurgitation and significant improvement in signs and symptoms with subsequent follow-up.
