Embolization of Left Ventricular Outflow Tract Calcification After TAVR With a Self-Expanding Valve.

ABSTRACT:

Background

Severe aortic stenosis with extensive left ventricular outflow tract (LVOT) calcification poses challenges during transcatheter aortic valve replacement.

Case summary

An 85-year-old man with severe aortic stenosis and extensive annular-to-LVOT calcification underwent transcatheter aortic valve replacement with a Navitor system (Abbott). To avoid conduction disturbances, the valve was deployed within the membranous septum under intracardiac echocardiography guidance, using partial recapture and the distal opening technique. Immediately after the procedure, displaced LVOT calcification embolized the left main coronary artery, leading to cardiogenic shock. The patient was successfully treated with emergency percutaneous intervention and was discharged without other e
