Article Abstract
Background: Left ventricular (LV) pseudoaneurysm is a rare and life-threatening sequela of atrioventricular (AV) groove disruption.
Case Summary: A 73-year-old woman with giant cell arteritis on immunosuppressive therapy presented with dyspnea. Blood cultures revealed Enterococcus faecalis native mitral and aortic valve endocarditis with severe mitral and aortic regurgitation. She underwent bioprosthetic aortic and mitral valve replacement. After separation from cardiopulmonary bypass, she developed refractory AV groove bleeding requiring venoarterial extracorporeal membrane oxygenation. After decannulation and recovery, she returned with dysrhythmia and was diagnosed with an LV pseudoaneurysm, necessitating surgical reintervention.
Discussion: It is important to recognize LV pseudoaneurysm as a rare but serious complication of valve surgery, especially after AV groove bleeding. Timely diagnosis and surgical intervention are essential for patient survival.
Take-home Messages: LV pseudoaneurysm is a rare but life-threatening complication after valve surgery, especially in high-risk patients. Prompt diagnosis and surgical repair are critical for survival.

Complete detachment of the aortic root following a Bentall procedure is an exceptionally rare complication. The vast majority of reported cases are secondary to prosthetic valve endocarditis or underlying vasculitis. Currently, the most reliable treatment for aortic root dehiscence-particularly in the context of prosthetic valve endocarditis-is repeat root replacement, typically via a second Bentall procedure or with the use of a homograft or allograft.

Background: Ventricular pseudoaneurysm formation due to longstanding lead erosion is rare, and standardized guidelines for diagnosis and management are limited.
Case Summary: We present a case of a right ventricular pseudoaneurysm noted on computed tomography after a patient with a pacemaker, originally placed in 2013, was admitted for respiratory failure. PolyJet three-dimensional printing was employed to assist in presurgical planning and evaluating the spatial anatomic relationship of the lead to the ventricular outpouching.

Background: Coronary artery pseudoaneurysms (CAP) are rare, especially without any history of coronary angioplasty and coronary bypass graft. The symptoms range from asymptomatic to cardiogenic shock. Because of its rarity and variable symptoms, patients with CAP should be treated with an individualized approach.

Background: We present a multimodality imaging study of a rare case of postsurgical chronically evolved pseudoaneurysm with a possible rupture buffered by the huge thrombus.
Case Summary: A patient known for previous late presentation myocardial infarction complicated by shock and ventricular septal defect and treated with surgical repair and triple coronary artery bypass grafting, was directed to our hospital for severe mitral regurgitation. Computed tomography, cardiac magnetic resonance, and echocardiography, in a multimodality approach, revealed a huge postsurgical cardiac pseudoaneurysm, with an extensive thrombus and the native pericardium not perfectly distinguishable from pseudoaneurysm tissue or surgical patch.
