Aortic root operation for aortic aneurysm: Valve replacement versus valve sparing procedures

摘要

BackgroundAortic root replacement (Bentall operation) or Aortic valve sparing (David operation) are alternative surgical techniques for the treatment of aortic root aneurysm. The aim of the current study was to compare our 30-days mortality, post-operative care and complications associated with both procedures.MethodsFrom January 2015 to December 2017, 45 consecutive patients (40 men; 88.9%), with mean age 43.2?±?6.55 years underwent either Bentall operation (Group A: 30 patients; 66.7%) or David operation (Group B: 15 patients; 33.3%); according to surgeons' preference or expertise.Group A patients were significantly older (47.1?±?7.6 vs. 39.3?±?5.5 years; P?=?0.001), more hypertensive (10 patients; 33.3% vs. none; P?=?0.019), had higher serum creatinine level (1.3?±?0.28 vs. 39.3?±?5.5 vs. 1.07?±?0.12?mg/dl; P?=?0.004), larger LVEDD (6.03?±?0.4 vs. 5.40?±?0.16?cm; P?
