Successful surgical management of a rare left ventricular pseudoaneurysm following balloon aortic valvuloplasty in an infant

Left ventricular pseudoaneurysm is an exceedingly rare, life-threatening complication following percutaneous balloon aortic valvuloplasty. We report a 1-month-old infant presenting with a large left ventricular pseudoaneurysm after successful valvuloplasty for critical aortic stenosis. Multimodal imaging confirmed the diagnosis. The patient underwent successful surgical resection and bovine pericardial patch repair. This case emphasises the importance of early surgical intervention for favourable outcomes.
