Single centre experience of double valve replacement using mechanical valves

Abstract

Introduction: Cardiac valvular disease in India is most commonly caused by Rheumatic aetiology, many of which end up getting operated for the same. There is still existing controversy about the selection of ideal valves that can be used for replacement. Objective: Objective of this study was to retrospectively analyse the variable which can be easily assessed in the patients undergoing DVR (Double Valve replacement) using mechanical valves for its outcomes. Methods: All the patients who underwent DVR + Tricuspid valve repair/annuloplasty between October 2017 to January 2019, were identified and retrospectively their data was analysed. Results: 72 patients who underwent the procedure. Most common aetiology was Rheumatic. 69.4% were in NYHA (New York Heart Association) class II, 33.33% had chronic atrial fibrillation. 45.6% had associated tricuspid valve disease, and no chordae was preserved in 27.7%. Overall mortality was 5.5% Conclusion: The study revealed a favourable survival outcome after DVR surgery. The operative mortality in patients undergoing DVR depends on intra operative factors like total surgical time, bypass time and aortic cross clamped time and has improved remarkably over time, with the improvisation of extracorporeal circulation methods, myocardial protection techniques and postoperative management.
