discussion the reason is that we assess the relative and not absolute differences of the tracer uptake in this imaging modality. there may be other findings on mpi images which could help us overcome this pitfall, including detecting wall motion abnormalities, lung uptake of the tracer, or transient ischemic dilation. another important issue is the ecg changes during exercise stress testing, wh...

BACKGROUND The aim of the study is to assess the prevalence of anomalous origin of the coronary artery in cardiac computed tomography (CT) and to evaluate its coexistence with other congenital heart disease. MATERIALS AND METHODS 7,115 patients, who underwent 64-slice or dual source cardiac CT in the years 2005-2011 were screened for the presence of anomalous origin of the coronary artery. ...

BACKGROUND Coronary artery anomalies (CAAs) are congenital variations of one or more of the coronary arteries and they are an uncommon but important cause of chest pain and, in some cases, sudden cardiac death. Anomalies of coronary arteries may be found incidentally in 0.3-1% of healthy individuals. The three types of coronary artery anomalies are anomalies of origin, anomalies of course and a...

Abstract Background Dual left anterior descending (LAD) coronary artery is a rare congenital anomaly. To date, eleven variants of dual LAD have been described with three published reports type X LAD. Here, we describe new variant short masquerading as 1 Case presentation A 42-year hypertensive female presented recent onset angina treadmill test positive for inducible ischemia. Coronary angiogra...

BACKGROUND AND OBJECTIVES Coronary artery anomalies are found in approximately 1% of patients undergoing diagnostic coronary angiography (CAG). Angiographic recognition of these vessels is important because of their clinical significance and importance in patients undergoing coronary angioplasty or cardiac surgery. There are fairly enough reports concerning the incidence of coronary anomalies i...

Background: Coronary pulmonary fistula is a rare clinical entity. Majority of them are clinically silent. But rarely chest pain, myocardial ischaemia and heart failure may be the presenting features. Coronary artery fistulas originate predominantly from the right coronary artery and are not associated with hemodynamic abnormalities or other congenital heart diseases. Case Presentation: Here we ...

Congenital anomalies of the coronary arteries are uncommon and can present a diagnostic challenge. The authors present the case of a patient with recurrent chest pain during exertion admitted for acute coronary syndrome. Coronary angiography revealed no coronary lesions but showed that the right coronary artery originated from the anterolateral aortic wall, above the sinuses of Valsalva, leadin...

Coronary artery originating from pulmonary is a rare congenital vascular malformation, which generally presents corresponding clinical symptoms with the growth of patients’ age. CTA and angiography are important methods for diagnosis this disease, provide evidence treatment strategies patients. Keywords: bicardiovascular malformations; coronary arteries; cta.

Congenital absence of left circumflex artery is a rare congenital anomaly of the coronary arteries. The prevalence of the anomaly in different studies ranges from 0.6% to 1.3%. Of these, 80% are benign and asymptomatic and 20% are clinically important. We report a 56-year-old man presented with acute resting chest pain who was diagnosed as having acute anterolateral infarction accompanied by el...

Objectives Coronary artery anomalies are uncommon, but important cardiac malformations, representing the second commonest cause of death in young athletes. Methods We utilized computerized tomographic angiography to screen and precisely delineate coronary artery anomalies in patients with minimal cardiac symptoms. Results During 3.5-year period, we performed 2888 computerized tomographic an...
