Abstract:
Destruction of the intervalvular fibrous body (IFB) due to infective endocarditis (IE) warrants a complex operation involving radical debridement of all infected tissue, followed by double valve replacement (aortic and mitral valve replacement) with patch reconstruction of the IFB. This study assesses the 5-year outcomes in patients undergoing this complex procedure for treatment of double valve IE with IFB involvement. METHODS A total of 127 consecutive patients underwent double valve replacement with reconstruction of the IFB for active complex IE between January 1999 and December 2018. Primary outcomes were 3-year and 5-year survival, as well as 5-year freedom from reoperation. RESULTS Patients’ mean age was 65.3 ± 12.9 years. Preoperative cardiogenic shock and sepsis were present in 17.3% and 18.9%, respectively. The majority of patients (81.3%) had undergone previous cardiac surgery. Overall, 30-day and 90-day mortality rates were 28.3% and 37.0%, respectively. The 3- and 5-year survival rates for all patients were 45.3 ± 5.1% and 41.8 ± 5.8%, and for those who survived the first 90 postoperative days 75.8 ± 6.1% and 70.0 ± 8.0%, respectively. The overall 5-year freedom from reoperation was 85.1 ± 5.7%. Preoperative predictors for 30-day mortality were Staphylococcus aureus [odds ratio (OR) 1.65; P = 0.04] and left ventricular ejection fraction (LVEF) & lt;35% (OR 12.06; P = 0.03), for 90-day mortality acute kidney injury requiring dialysis (OR 6.2; P = 0.02) and LVEF & lt;35% (OR 9.66; P = 0.03) and for long-term mortality cardiogenic shock (hazard ratio 2.46; P = 0.01). CONCLUSIONS Double valve replacement with reconstruction of the IFB in patients with complex IE is a challenging operation associated with high morbidity and mortality, particularly in the first 90 days after surgery. Survival and freedom from reoperation rates are acceptable thereafter, particularly considering the severity of disease and complex surgery.
