Late presentation of aortic root abscess in endocarditis with coronary ischemia.

Formation of a large aortic root abscess is an infrequent complication of aortic valve endocarditis in adults. Extrinsic compression of the coronary arteries by this abscess is still rarer. Here, we report a case of a 22-year-old male with aortic root abscess, who presented 2 months after the completion of treatment of endocarditis with exertional angina. Coronary angiogram revealed compression of proximal left anterior descending and left circumflex arteries by the abscess. The patient was successfully treated with pericardial patch exclusion of the abscess cavity and coronary artery bypass graft. The presentation of aortic root abscess with myocardial ischemia as a late complication of treated endocarditis has not been reported earlier.
