Complete Aortomitral Curtain Dehiscence Resulting in Large Pseudoaneurysm 6 Weeks After Aortic Root Replacement

Abstract

This case report presents a unique challenge of complete aortomitral curtain dehiscence and a large pseudoaneurysm 6 weeks post-aortic root replacement in a patient with infective endocarditis. It underscores the importance of meticulous follow-up in patients who have undergone complex aortic surgeries, especially those with infective endocarditis. The patient's subtle symptoms of occasional dyspnea and lightheadedness highlight the necessity for a comprehensive evaluation and a high index of suspicion. The aortomitral curtain was successfully reconstructed using a bovine pericardial patch, managing the pseudoaneurysm and restoring heart structural integrity. This case also emphasizes the limitations of current diagnostic criteria for infective endocarditis in the presence of intracardiac prosthetic material, and the need for advanced imaging and interdisciplinary consultations to enhance diagnosis and patient management.
