AORTIC ROOT REPLACEMENT: CLASSICAL BENTALL VERSUS COPELAND’S MODIFICATION

Abstract

Objective: To compare the aortic root replacement with composite aortic valve graft and to analyze these
techniques.
Study Design: Retrospective observational.
Place and Duration of Study: Armed Forces Institute of Cardiology and National Institute of Heart Diseases
(AFIC/NIHD) Rawalpindi, between 2007 to 2016.
Material and Methods: Study was conducted at Armed Forces Institute of Cardiology and National Institute of
Heart Diseases (AFIC/NIHD) Rawalpindi between 2007-2016, 59 patients underwent Aortic root replacement
with composite aortic valved graft. Initial 28 patients underwent the Classical Bentall Procedure and in the last 31
patients Copeland’s modification of Bentall procedure was employed.
Results: Mean age was 39.80 ± 14.24 and male to female ratio was 3:1. 13.6% patients had Marfan syndrome,
15.3% patients underwent concomitant Mitral Valve replacement. Statistically significant difference was observed
between Classical and modified Bentall procedure in Cross Clamp Time (p=0.02), Total Inotrope Duration
(p=0.01), Total Chest Drainage (p=0.04), Total Red Cell Concentrate (RCC) Transfused (p=0.01), Re-opening Rate
(p=0.01) and Mortality (p=0.01).
Conclusion: Copeland’s Modification of Bentall Procedure provides superior post-operative outcome as
compared to the Classical Bentall procedure
