Abstract
INTRODUCTION AND IMPORTANCE
Triple-valve replacement in active infective endocarditis has rarely been reported. This paper is the first report of a triple-valve replacement performed in endocarditis with septic shock and the first presentation of multivalvular endocarditis due to Rhizobium radiobacter.
CASE PRESENTATION
A 26-year-old patient with a neglected ventricular septal defect referred to us in septic shock, with multiple organ failure, severe biventricular dysfunction, and pulmonary hypertension, due to Rhizobium radiobacter infective endocarditis affecting the aortic, tricuspid and pulmonary valves. Initially, he was deemed unfit for surgery. However, after clinical stabilization, triple-valve replacement, aortic annular abscess repair, membranous septum aneurysm resection, and ventricular septal defect patch closure were performed. The postoperative evolution was good; both ventricles showed functional recovery after six months.
CLINICAL DISCUSSION
Although surgery provides the best chances of survival in endocarditis with septic shock, reportedly, most cases are considered inoperable. Clinical stabilization under intensive care using specific therapies to manage septic shock, myocardial dysfunction, and pulmonary hypertension was crucial for surgery success. Custodiol® cardioplegia, and replacement of the right-sided valves using a beating-heart technique were used to reduce the myocardial ischemic time.
CONCLUSION
Rhizobium radiobacter, an opportunistic gram-negative bacterium, potentially may cause multiple valve endocarditis. Patients with endocarditis and septic shock initially considered inoperable can still benefit from surgery after tenacious intensive care (cytokine hemoadsorption and levosimendan are helpful in this process). In complex multivalvular procedures, a beating heart technique to replace the right-sided valves should be considered to minimize the duration of myocardial ischemia.
