Background: This study assessed the application value of 64-slice spiral computed tomography angiography (CTA) in a follow-up evaluation of patients receiving coronary stent implantation. Materials and Methods: A total of 468 patients who underwent percutaneous coronary intervention (PCI) at our hospital between January 2013 and October 2016 were selected for this study. Coronary angiography an...

Introduction. Coronary artery aneurysms are rare disorders, especially left main coronary aneurysm. In literature there number of reported cases with aneurysms, various localization, size, clinical presentation and way treatment. There is no unique consensus about the most adequate treatment in these patients; surgery still preferable, although some new experiences percutaneous The decision mad...

Congenital coronary pulmonary artery fistula (CAF) is rare, and systemic-to-pulmonary artery fistula (SPAF) is even more so. Furthermore, congenital coronary pulmonary fistula associated with congenital SPAF is extremely rare. As far as we know, CAF and SPAF connected with an aneurysm have not been described very often. We described an 83-year-old woman with an aneurysm originating from a CAF c...

Coronary artery aneurysm (CAA), defined as dilatation of the coronary artery exceeding 50% of the reference vessel diameter, is uncommon and occurs in 5% of coronary angiographic series.1 CAAs are termed giant if their diameter exceeds the reference vessel diameter by 4 times or if they are 8 mm in diameter.2 Atherosclerosis accounts for the vast majority of CAAs in adults, whereas Kawasaki dis...

To study the newly mentioned significance of the obstructive lesion morphology in coronary artery disease (CAD), a study has been designed to compare this feature between patients having stable angina (SA) or unstable angina (UA) who underwent coronary angiography in Tehran Heart Institute. Study objectives were detection of the angina producing artery (AP A) and its morphologic lesion typ...

Behçet's disease (BD) is a multiorgan vasculitis of unknown origin, with characteristic skin lesions, recurrent uveitis and neurological manifestations [1–3]. Here we present a case of diffuse coronary artery aneurysms involving three major vessels and its appropriate medical treatment. A 45-year-old man visited our cardiology outpatient clinic with a 2-month history of progressive exertional c...

A 52-year-old man with diagnosis of post-infarction unstable angina. Coronary angiography revealed 90% luminal obstruction in the middle third of the right coronary artery and 90% in the marginal branch of the circumflex artery. After the administration of clopidogrel 300 mg associated with acetylsalicylic acid, the patient underwent the implantation of a sirolimus-eluting stent (CYPHER; Johnso...

Background: Coronary angiography consists of the selective injection of contrast agents in coronary arteries. Optimal strategy for heparin administration during coronary angiography has yet to be determined. We assessed the effect of heparin administration during coronary angiography on vascular, hemorrhagic, and ischemic complications.Methods: Five hundred candiates for diagnostic coronary ang...

Anomalous left coronary artery from pulmonary (ALCAPA) is a rare congenital anomaly with high rate of mortality in first year life. It one the most common causes cardiomyopathy and myocardial ischemia children. In present scenario, computed tomography (CT) angiography sufficient for diagnosis ALCAPA, eliminating need invasive angiography. CT performed infants suspicion ALCAPA technically challe...
