opportunities in improving left ventricular remodelling and clinical outcome following surgical and trans-catheteraortic valve replacement

Frontiers of Medicine 2021, Volume 15, Issue 3,   Pages 416-437 doi: 10.1007/s11684-021-0852-7

Abstract: Over the last half century, surgical aortic valve replacement (SAVR) has evolved to offer a durable andefficient valve haemodynamically, with low procedural complications that allows favourable remodellingThe latter has become more challenging among elderly patients, particularly following trans-catheteraortic valve implantation (TAVI).surgery requires comprehensive assessments from aortic valve energy loss, valvular-vascular impedance

Frontiers of Medicine 2016, Volume 10, Issue 3,   Pages 351-355 doi: 10.1007/s11684-016-0465-8

Abstract:

This paper discusses two male patients with severe aortic stenosis, whose right coronary arteries(RCA) were completely occluded during transcatheter aortic valve implantation (TAVI), leading to fatalBoth patients were admitted for “severe aortic stenosis,” and TAVIs were performed.The second patient’s blood pressure fluctuated greatly for several minutes after the valve implantation
