Catheter-induced left main coronary artery (LMCA) vasospasm is a rare complication of coronary angiography that confounds the decision for coronary artery bypass graft (CABG) surgery. We report two cases of catheter-induced LMCA vasospasm. The first case was a 68-year-old woman who presented 6 years after CABG for presumed severe LMCA ...

INTRODUCTION: Coronary artery disease in people under 30 years is relatively uncommon, but once a disease occurs it brings a significant morbidity and psychological effects. CASE REPORT: We reported a 28-year-old patient presenting atypical symptoms after sincopa and non-specific changes on electrocardiogram at admission. After noninvasive and invasive cardiology diagnostic ...

This study sought to determine angiographic and clinical outcomes among patients with acute coronary syndrome (ACS) presenting with isolated anterior ST-segment depression on 12-lead electrocardiogram (ECG). In patients with ACS, anterior ST-segment depression on 12-lead ECG may represent plaque rupture with: 1) acute thrombotic occlusion with elevation of cardiac biomarkers ...

Left main coronary artery aneurysms are very infrequent (0.1%) and the majority is related to atherosclerotic obstructive lesions. We describe a young male having no conventional coronary risk factors presenting with acute inferior wall myocardial infarction. Coronary angiography revealed a prominent aneurysm of the left main coronary artery with selective ...

BACKGROUND: The current consensus in the literature is that the anterolateral branch of the anterior humeral circumflex artery provides the main blood supply to the humeral head. While the artery is disrupted in association with 80% of proximal humeral fractures, resultant osteonecrosis is infrequent. This inconsistency suggests a greater role ...

Aortico-left ventricular tunnel (ALVT) is a rare congenital paravalvar communication between the aorta and the left ventricle. This anomaly has been associated with the right coronary artery (RCA) arising directly from the tunnel. Surgical repair of this later condition is challenging and is usually undertaken by closure of the ventricular ...
