Robotic patch repair of a ventricular septal aneurysm during an aortic valve replacement surgery.

Interventricular septal aneurysm represents a rare cardiac anomaly traditionally associated with ischaemic heart disease or healed congenital ventricular septal defects. In this report, we present the first documented case of robot-assisted surgical repair of an interventricular septal aneurysm. Our 47-year-old male patient presented with symptomatic heart failure secondary to moderate aortic stenosis and severe aortic regurgitation. During pre-operative evaluation, imaging revealed an incidental membranous interventricular septal aneurysm without an associated shunt. The patient underwent successful robot-assisted transthoracic patch repair of the septal aneurysm concurrent with aortic valve replacement. This case demonstrates the feasibility of robot-assisted repair for complex cardiac anomalies, potentially expanding the horizons of minimally invasive cardiac surgery.
