Abstract
BACKGROUND: Left ventricular pseudoaneurysm (LVPA) is a rare yet potentially life-threatening complication following myocardial infarction or cardiac surgery. Although surgical repair has traditionally been the standard treatment, advances in percutaneous interventions have expanded management options, particularly for patients in hemodynamically unstable condition and those at high surgical risk. CASE SUMMARY: We present a case of LVPA secondary to ST-segment elevation myocardial infarction successfully treated with percutaneous device closure. DISCUSSION: This case highlights the feasibility and efficacy of this approach in judiciously selected patients. TAKE-HOME MESSAGES: In cases of LVPA in patients in hemodynamically unstable condition deemed at high risk for surgery, percutaneous transcatheter closure using an atrial septal defect occluder offers a safe and effective alternative to open surgical repair. Transcatheter closure of LVPA can provide durable results, as evidenced by complete resolution of the pseudoaneurysm, stable device positioning, and sustained hemodynamic stability at 6-month follow-up.
