Key result
Percutaneous transcatheter closure of a mitral paravalvular leak using a Cocoon duct occluder via an anterograde approach without an arteriovenous loop was successfully performed.
Case Report (n=1)
Percutaneous transcatheter closure of a mitral paravalvular leak can be successfully performed via an anterograde approach without an arteriovenous loop using a duct occluder device.
One successful case does not support practice change; leaves open generalizability of simplified anterograde closure.
Paravalvular leak (PVL) is a rare but potentially serious complication of surgically implanted prosthetic heart valves. Patients who have PVL can be asymptomatic or present with haemolysis, heart failure, or endocarditis. The goldstandard treatment for prosthetic-valve PVL is surgery to repair or replace the valve but carries higher operative risk compared to the initial procedure. In view of this, percutaneous transcatheter closure of PVL is becoming an increasingly attractive alternative strategy. In this report, we describe a case of mitral PVL in a patient with double-valve replacement, which was successfully closed using Cocoon duct occluder device (Vascular Innovations Co., Ltd, Thailand) via ante-grade approach, guided by transesophageal echocardiography (TEE) and fluoroscopy and without complete arterio-venous loop.

M et al. (2013) conducted a case report in Mitral paravalvular leak (n=1). Percutaneous transcatheter closure using Cocoon duct occluder device via anterograde approach was evaluated on Procedural success. Percutaneous transcatheter closure of a mitral paravalvular leak using a Cocoon duct occluder via an anterograde approach without an arteriovenous loop was successfully performed.
