- Abstract
- Background: Although less frequently encountered, aortic valve stenosis is associated with complications separate from its hemodynamic burdens, such as infective endocarditis. Case Summary: We report the case of a 77-year-old female patient with regular cardiac follow-up in the setting of an asymptomatic severe aortic stenosis, who presented to the emergency department with signs and symptoms of sepsis and acute decompensated heart failure. Echocardiography revealed two vegetations attached to the tricuspid valve, an abscess of the anterior aortic ring, and a high-velocity ventricular septal defect. The patient was started on adequate antibiotic therapy. Surgical treatment in an urgent manner (within a few days) was decided by the Heart Team, in accordance with the ESC guidelines on the management of infective endocarditis. Whilst awaiting surgery, the patient presented with a sudden hemodynamic deterioration a few days after diagnosis, with cardiopulmonary arrest and subsequent death. Discussion: We hypothesize that the patient developed an infective endocarditis of the degenerated stenotic aortic valve with extension from left to right via a ventricular septal defect, the development of which was facilitated by the high trans-aortic valve gradient. Some reported cases describe a ventricular septal defect as a complication of native aortic valve endocarditis, though not all involve concomitant aortic stenosis. In conclusion, our case illustrates a very rare scenario of infective endocarditis complicating aortic stenosis with fulminant development. This case highlights a rare, albeit severe complication associated with aortic stenosis and therapeutic challenges in managing the dismal evolution of endocarditis in this setting.
