Key result
Aneurysm resection with reinforced HeartMate 3 inflow cannula placement achieves successful positioning without obstruction.
Why the study?
Large left ventricular aneurysms create challenges for durable LVAD implantation due to altered anatomy and poor myocardial integrity.
Case Report (n=1)
Complete resection of a giant left ventricular aneurysm with reinforced inflow cannula placement is a feasible technique for HeartMate 3 LVAD implantation when standard apical cannulation is precluded.
May enable LVAD implantation after aneurysm resection in complex cases; hypothesis-generating, multicenter data needed before adoption.
Large left ventricular aneurysms pose significant challenges for durable left ventricular assist device implantation because of altered anatomy and poor myocardial integrity. A 60-year-old man with end-stage ischemic cardiomyopathy and a complex, multilobulated apical aneurysm arrived in cardiogenic shock. Standard apical cannulation was impossible because of extensive aneurysmal degeneration. The aneurysm was fully resected down to healthy myocardium. The left ventricular assist device inflow cannula was placed at the aneurysm neck and secured with circumferential pledgeted sutures. Early postoperative imaging showed cannula positioning without obstruction. Complete aneurysm resection and reinforced inflow placement may be a feasible approach to this complex issue.

Tharakan et al. (2026) conducted a case report in End-stage ischemic cardiomyopathy with a giant left ventricular aneurysm (n=1). HeartMate 3 implantation after complete aneurysm resection was evaluated. Complete aneurysm resection and reinforced HeartMate 3 inflow cannula placement at the aneurysm neck was feasible with good cannula positioning and no obstruction on early postoperative imaging.
