title: Percutaneous closure of a giant left ventricular wall pseudoaneurysm: Anterograde approach with a double snare technique.
abstract: Left ventricular pseudoaneurysm is a rare complication of acute myocardial infarction, cardiac surgery, trauma or infection. Since surgical repair is associated with high morbidity and mortality, percutaneous closure has been described as an alternative. In this regard, we present a case in which a symptomatic large left ventricular pseudoaneurysm was treated by percutaneous closure due to the patient's high surgical risk, using a double snare technique. Despite the technical difficulties, this procedure had a good final result followed by clinical success, confirming that this procedure is an effective alternative to surgery in high-risk patients.
