x-ray coronary angiography has been a gold standard in the clinical diagnosis and interventional treatment of coronary arterialdiseases for decades. in angiography, a sequence of images is obtained, a few of which are suitable for physician inspection. thispaper proposes an automatic algorithm for the extraction of one or more frames from an angiogram sequence, which is most suitablefor diagnos...

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital cardiac malformation. We report three cases of ALCAPA who survived to adulthood. The first case was a 51-year-old woman who complained of typical chest pain that was diagnosed with ALCAPA using cardiac catheterization and coronary computed tomographic angiography (CTA). The second case was a 30-...

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 type, de...

A 40 year old women with uncomplicated delivery 13 days before, presented at our emergency department with typical chest pain with onset three hours earlier. The EKG showed negative T waves in leads I, V5 and V6. Laboratory values showed: CK 1752 U/L (normal value 50-200 U/L) and Troponin I 0.21 μg/mL (normal value <0.16 μg/mL). Transthoracic echocardiography (TTE) revealed severe hypokinesia o...

BACKGROUND Coronary artery anomalies are not common, but could be very serious. OBJECTIVES This study determines the frequency of coronary anomalies and normal variants by multi-detector-row computed tomography (MDCT). PATIENTS AND METHODS The results of cardiac MDCT study in 2697 consecutive patients were analyzed retrospectively. Acquisition was performed by a 64-detector row CT machine. ...

Congenital anomalies in the origin, course or distribution of the epicardial coronary arteries are found in 1 to 2 percent of the population. Asymptomatic coronary artery anomalies are generally diagnosed incidentally by routine coronary angiography or during autopsy. Approximately 80% of congenital anomalies of the coronary arteries are benign, while 20% of coronary artery anomalies produce li...

INTRODUCTION The correlation between erectile dysfunction (ED) and coronary artery disease has been emphasized and ED has been recognized as a potential independent risk factor and/or predictor of coronary artery disease (CAD). We evaluated the association between the number of occluded coronary arteries in myocardial infarction (MI) patients with the severity of ED, and investigated the influe...

Congenital anomalies of coronary arteries are relatively frequently found in general population (their incidence reaches 0.2-0.9%) [1,2]. Most of them are benign and do not require interventional or surgical treatment, but in some cases them can result in sudden death or myocardial infarction [3]. Coronary CT-angiography (CTA) or MR-angiography are effective imaging modalities for non-invasive ...

PURPOSE To compare the imaging time and image quality obtained with whole-heart coronary magnetic resonance (MR) angiography performed with five- and 32-channel coils in healthy subjects and determine the accuracy of MR angiography performed with 32-channel coils in the detection of obstructive coronary artery disease (CAD). MATERIALS AND METHODS The institutional review board approved the st...
