Successful Percutaneous Closure of Traumatic Right Ventricular Free Wall Rupture Using Amplatzer Vascular Plug Devices

摘要

Ventricular free wall rupture (VFWR) is a rare entity and is mostly related to post myocardial complications usually involving left ventricle. In traumatic chest injuries, the right ventricle (RV) is more commonly involved due to its anatomic and structural vulnerability, as in our case. Survival, although rare, has almost always been secondary to urgent surgical repair, which is the current standard of care for such cases. However, extremely tenuous hemodynamic parameters preclude urgent surgical interventions in most of these cases. Surgical repair was considered to have prohibitive risk in our case also due to multiple comorbidities. Our case offers a unique perspective into the feasibility and safety of percutaneous closure of VFWR with devices such as Amplatzer Vascular Plug (AVP) II under transesophageal echocardiography (TEE) and angiographic guidance in patients who survive VFWR. The lack of randomized evidence to standardize the duration and regimen of antiplatelet therapy following placement of these devices is to be noted.
