Aortic Valve Leaflet Rupture Causing Delayed Left Main Coronary Ostial Obstruction During Valvuloplasty Preceding TAVR.

A 69-year-old man with mediastinal radiation history underwent balloon valvuloplasty before transcatheter aortic valve replacement, which caused aortic leaflet rupture leading to unstable severe aortic regurgitation and subsequent left main ostial obstruction. A balloon-expanding valve was implanted to capture the ruptured leaflet and a left main stent was placed. (Level of Difficulty: Advanced.).

Papillary fibroelastoma presenting with multi-organ symptoms.

Papillary fibroelastomas are a rare cardiac neoplasm typically found on the left side of the heart, and most commonly on the aortic valve, which can present with cardiac or neurologic symptoms. A 51-year-old woman with no cardiac history presented to a resident clinic with complaints of left-sided facial paresthesias and palpitations for 1 month. Echocardiographic imaging showed a mass on the aortic annulus, concerning for a cardiac tumor. Due to the risk of possible embolization, if the tumor was a myxoma, the patient required intrathoracic surgery. During the intrathoracic procedure the mass was confirmed to be a papillary fibroelastoma and the patient had the mass removed without any complications. Papillary fibroelastomas are found in less than 1% of the population but can present clinically with a wide variety of symptoms. Patients with this neoplasm are at risk for severe complications, due to embolization, potentially causing cerebrovascular accidents or myocardial infarctions. We present a case of a papillary fibroelastoma producing both cardiac and neurologic symptoms.
