Challenges and opportunities in improving left ventricular remodelling and clinical outcome following surgicaland trans-catheter aortic 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-catheter aorticvalve implantation (TAVI).surgery requires comprehensive assessments from aortic valve energy loss, valvular-vascular impedance

The evolution of surgical and medical treatment of aortic root aneurysm

Xu Yu Jin,Li Yuan,Mario Petrou,John R. Pepper

Frontiers of Medicine 2014, Volume 8, Issue 4,   Pages 427-432 doi: 10.1007/s11684-014-0385-4

Abstract:

Since first report of aortic root replacement in 1968, the surgical risk and long term outcome ofpatients with aortic root aneurysm have been continuously improving.In the last 30 years, the surgical approach is also evolving towards more valve conservation with prophylacticalTranslational research has also led to emerging surgical innovation and new drug therapy.
