Complicated Native Aortic Valve Endocarditis: Complexities of Medical Optimisation Prior to Surgical Repair for Large Vegetations With Systemic Emboli

A 43-year-old male with no history of valvular disease but ongoing intravenous drug use presented with acute confusion, pyrexia, and Osler’s nodes. Transthoracic echocardiography uncovered a large 17 x 15 mm-sized vegetation on the aortic valve, causing moderate-to-severe aortic regurgitation. Subsequent multi-organ compromise and complexities regarding treatment adherence delayed surgical intervention; thus, six weeks of antibiotic therapy and medical optimisation, in close collaboration with cardiology, microbiology, and cardiothoracic teams, enabled definitive aortic valve repair to be performed. This case highlights the challenges encountered when managing this life-threatening condition and the obstacles of enacting the guidelines recommendations regarding the timing of surgical intervention. Our case portrays the effectiveness of medical management as bridge-to-surgery in patients not in a position to undergo immediate surgical repair.
