Coronary arteriovenous fistulas are among rare anomalies of coronary arteries. Role of X-ray angiography is well established in identification and characterization of these anomalies, however there accurate course and termination is often not defined. We demonstrate role of routine cardiovascular MRI in non-invasively diagnosing and characterizing the course and termination of these anomalous c...

Anomalous origin of the right coronary artery is a rare congenital anomaly, but is associated with sudden death. Originating from the opposite sinus of Valsalva, an interarterial course and an intramural course are especially considered as the risk factor for fatal cardiac events. Surgical indication remains controversial because many patients are asymptomatic. A 52-year-old man with anomalous ...

ST-segment elevation MI (STEMI) is a rare presentation in patients with coronary artery anomalies. In these patients, the identification of the culprit lesion and its treatment may be difficult, particularly in the emergency setting of primary percutaneous coronary intervention (PCI). From January 2008 to April 2011, 1015 STEMI patients received coronary artery angiography and primary PCI in ou...

OBJECTIVE To evaluate the use of cardiovascular magnetic resonance (CMR) to visualize angiographically-detected congenital coronary artery fistulas in adults. METHODS CMR techniques were used to study 13 patients, recruited from the Dutch Registry, with previously angiographically diagnosed fistulas. RESULTS Coronary fistulas were detected in 10 of 13 (77%) patients by CMR and, retrospectiv...

Eighty-five patients with accelerated (preinfarction) angina are reported. Six suffered acute myocardial infarction awaiting catheterization and coronary angiography, so were not studied. Seventy-nine had coronary arteriography and other angiographic and hemodynamic studies. Fifteen of these 79 patients had normal coronary arteriograms; 64 had significant coronary artery obstruction. The clinic...

Congenital coronary anomalies are uncommon and are usually diagnosed incidentally during coronary angiogram or autopsy. Isolated coronary artery anomalies and the anomalous origin of left main stem (LMS) from the proximal portion of the right coronary artery or from the right sinus of valsalva are extremely rare. A 68 years old woman with atypical chest pains was referred for risk assessment fo...

Coronary anomalies comprise a diverse group of malformations, some of them asymptomatic with a benign course, and the others related to symptoms as chest pain and sudden death. Such anomalies may be classified as follows: 1) anomalies of origination and course; 2) anomalies of intrinsic coronary arterial anatomy; 3) anomalies of coronary termination. The origin and the proximal course of anomal...

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...

Background: Plasminogen activator inhibitor-1 (PAI-1) is a glycoprotein with inhibitory effects on the formation of plasmin from plasminogen by plasminogen activator. Thus, it prevents clot lysis in vessel walls. Several evidences prove the relationship between coronary artery disease and response to fibrinolytic therapy in patients with myocardial infarction with PAI-1 level. Opium addiction i...
