Prognostic Factors for Morbidity and Mortality in Redux Valve Surgery

Abstract

Objectives: Redux valve surgery is increasingly common in Algeria, and the aim of this study was to identify the risk factors for hospital morbidity and mortality in this type of surgery. Method :49 patients with a mean age of 51 years (20-67 years) and a sex ratio of 0.88 underwent redux valve surgery between January 2015 and december 2019. 79%), and in almost half of the cases (46%) the first operation was performed in our department; the most frequent reasons for repeat operations were mitral plasty dysfunction, expression of new valve damage and removal of mechanical prostheses due to infective endocarditis. The Euroscore was used to predict operative risk. Results: 80% of our patients were classified in the moderate risk group (score 3-5) with an expected mortality of between 2.90 and 2.94%. Our results show a mortality rate of 2.56% for these patients. The study of post-operative results revealed a number of cardiac complications (28.5% low output and 37% rhythm disorders), infectious complications (8% mediastinitis) and neurological complications (6%). The risk factors for operative mortality were multiple valve procedures (p=0.03), persistent atrial fibrillation or fibrillation that appeared postoperatively (p=0.05) and age over 70 (p=0.04). Conclusion: Valvular redux surgery with a single-valve procedure has an operative morbi-mortality, actuarial survival and post-operative functional benefit that are entirely comparable to those of a primary intervention; whereas in redux surgery with a multi-valvular procedure, the operative morbi-mortality is significantly higher, but the actuarial survival and functional benefit are comparable to those of a primary intervention
