Left Ventricular Outflow Obstruction From Mechanical Circulatory Support in Critical Aortic Stenosis: A Cautionary Tale.

We submit a cautionary tale of a patient with critical aortic stenosis presenting with acute myocardial infarction and cardiogenic shock, who underwent balloon aortic valvuloplasty, insertion of a transvalvular left percutaneous ventricular assist device and high-risk percutaneous coronary intervention, with a post-operative course complicated by outflow obstruction from the device itself.

Aortocoronary Saphenous Vein Graft Aneurysm: Diagnosis Using Color Doppler and Contrast Transesophageal Echocardiography.

• SVG aneurysm may be diagnosed using TEE, color Doppler, and UEA. • An extracardiac mass after CABG raises suspicion of an SVG aneurysm. • Demonstration of flow by color Doppler or UEA aids in diagnosing SVG aneurysm.
