Percutaneous closure of left ventricular pseudoaneurysm using simultaneous transseptal and transapical approach: a case report

Left ventricular (LV) pseudoaneurysm (PSA), also referred to as contained LV wall rupture, is a clinically uncommon but potentially life-threatening condition that can occur after myocardial infarction or cardiac surgery. If the anatomic characteristics of LV PSA are not eligible for the transfemoral approach, percutaneous closure of LV PSA can be technically difficult and appropriate approach selection may contribute to procedural success.

An enlarging LV PSA was discovered in a 65-year-old man with Marfan syndrome and three prior cardiothoracic surgeries. Arterial access was not possible due to invagination of the previously placed surgical graft in the descending thoracic aorta. This was managed with a novel approach of simultaneous transseptal LV access and direct puncture of PSA through the chest wall followed by a vascular plug placement.

This case demonstrates that percutaneous LV PSA closure using a hybrid approach of transseptal and direct apical puncture is a feasible and effective alternative for high-risk surgical candidates, although the anatomic characteristics are unsuitable for the transfemoral approach.
