Predictive factors, management, and clinical outcomes of coronary obstruction following transcatheter aortic valve implantation: insights from a large multicenter registry.

Objectives: This study sought to evaluate the main baseline and procedural characteristics, management, and clinical outcomes of patients from a large cohort of patients undergoing transcatheter aortic valve implantation (TAVI) who suffered coronary obstruction (CO).

Background: Very little data exist on CO following TAVI.

Methods: This multicenter registry included 44 patients who suffered symptomatic CO following TAVI of 6,688 patients (0.

Isolated left ventricle diverticula: a possible cause of atypical angina?

A 49-year-old woman with atypical chest pain was referred for a multidetector computed tomography examination of the coronary arteries after a positive electrocardiography stress test. No coronary atherosclerotic disease was observed on the coronary computed tomography scan. The only findings were 2 side-by-side basal left ventricle diverticula, suggested as a possible etiology for her symptoms and electrocardiographic changes.

Giant right coronary artery aneurysm on 64-MDCT.

An 81-year-old woman was referred for cardiac computed tomography-angiography (CCTA) after an extracardiac mass was found on echocardiography. CCTA found a giant atherosclerotic right coronary artery aneurysm with a maximal diameter of 80 mm, which was compressing the right atrium and right appendage, proximal superior vena cava, right ventricle inlet and tricuspid annulus.
