Fatal ischemic stroke related to nonpermissive peripheral artery access for percutaneous aortic valve replacement.

This report describes an 85 year-old man who underwent percutaneous aortic valve replacement (PAVR). With a logistic euroSCORE of 37%, the patient had been refused surgical aortic valve replacement because of an unacceptably high peri-operative risk. During the PAVR procedure, severe resistance was encountered when advancing the 21 Fr delivery catheter through the left iliac artery despite pre-dilatation with a 7 mm balloon. Following this, PAVR was promptly achieved without difficulty, with excellent valve positioning, no peri-valvular leak and good hemodynamics. However, transesophageal echocardiography revealed a mobile echogenic mass within the outflow tract of the left ventricle. The mass was retrieved with a cardiac bioptome manipulated via the left femoral artery through a 9 Fr sheath. A right cerebral ischemic stroke manifested shortly after the post-procedure and the patient died on the fourth post-operative day. Post-mortem findings revealed a left subclavian artery occlusion by iliac vascular tissue. This report highlights the imperative for device-specific vascular access screening criteria and the need to minimize device size in order to safely accomplish PAVR.
