Successful transvenous pacemaker implantation using a snare-assisted technique in a patient with severe tricuspid stenosis due to bioprosthetic valve dysfunction

Severe tricuspid stenosis is relatively rare, with limited evidence regarding optimal treatment strategies. Although rheumatic disease is the most common cause of acquired tricuspid stenosis,1 it can also result from bioprosthetic valve dysfunction after tricuspid valve replacement (TVR). Surgical intervention on the tricuspid valve (TV) carries a high risk of atrioventricular block, often requiring permanent pacemaker implantation.2 However, to our knowledge, no previous reports have described transvenous pacemaker implantation in patients with severe tricuspid stenosis due to bioprosthetic valve dysfunction.
