Abstract
Background
The incidence of infective endocarditis (IE) in patients undergoing redo mitral valve (MV) surgery was evaluated, and the outcomes of all patients who underwent redo MV surgery were analyzed.
Method
This was a retrospective review with prospective follow-up of electronic medical records from patients admitted for redo MV surgery at King Faisal Specialist Hospital and Research Center, Riyadh, Saudi Arabia, from 2009 to 2019.
Result
A total of 211 patients underwent redo MV surgery, 41 of whom (19.4%) had IE. In 51% of patients, IE developed after the initial MV surgery. MV stenosis was moderate/severe in 50 patients, while moderate/severe MV regurgitation was present in 89 patients. Factors influencing mortality included age, peripheral vascular disease, concomitant PVD procedures, red blood cell transfusions, preoperative mechanical valves, and active IE. Cardiac events were the leading cause of mortality (69.4%), followed by sepsis and brain-related causes.
Conclusion
While redo MV surgery has acceptable outcomes, the presence of IE, PVD, and concomitant procedures is a significant complication in these patients. Our study highlights the need for careful patient management and more in-depth research in this area.
