Background: A single coronary artery (SCA) is a rare anomaly encountered using conventional angiography. right (RCA) originating from left anterior descending (LAD) subtype of SCA. Only few cases are described in published literature. Case presentation: We this 55-year-old male who presented with angina pectoris. The anomalous RCA was suspected by angiogram and confirmed computed tomography (CT...
Coronary artery anomalies are rare, and their incidence varies from 0.6% to 1.3%. Conventional angiography is a commonly used modality for the assessment of coronary artery anomalies, but it may not identify and define the anatomy of anomalous arteries due to the complexity of the course and three-dimensional orientation of the arteries. We present a rare case of duplicated right coronary arter...
Introduction: Renal artery stenosis is the most prevalent disease of renal artery and has an important role in making hypertension and renal atrophy. Since in previous researches, despite high frequency of risk of cardiovascular disease in Iran, there did not exist any general research investigating risk factors of coronary artery disease and incidence of contemporary renal artery stenisis, ...
objectives to evaluate predictive value of vessel specific coronary artery calcium (cac) score in predicting obstructive coronary artery disease. patients and methods in this diagnostic test study we evaluated patients with coronary computed tomography angiography (ccta) and cac score which had been referred to two referral radiology center in tehran, iran and finally we selected 2525 patients ...
case presentation we present a case of a grade iii coronary perforation in which the double guiding catheter technique helped us to deliver the graft stent. conclusions the double-guiding technique is useful in emergency situations to increase the safety and efficacy of sealing a coronary perforation. introduction coronary vessel perforation is one of the most feared complications of coronary a...
In the past, coronary artery bypass grafting was the treatment of choice for patients with symptomatic multi vessel coronary artery disease, but in recent years per cutaneous transluminal coronary angioplasty (PTCA) accepted as an alternative approach to revascularization. To assess the initial success and in hospital results of coronary angioplasty of more than one lesion per procedure in pati...
the majority of coronary artery fistulas (cafs) are congenital. the anomaly accounts for 0.4% of congenital heart defects and approximately 50% of pediatric coronary vasculature anomalies. twenty percent of people with congenital cafs have other concomitant cardiac anomalies, most frequently aortic and pulmonary atresia and patent ductus arteriosus. it is worthy of note that caf with the tetral...
INTRODUCTION Coronary artery fistulas are abnormal communications between a coronary artery and a cardiac chamber or a major vessel (vena cava, pulmonary vein, pulmonary artery). They are usually diagnosed by coronary arteriography. Clinical presentations are variable depending on the type of fistula, shunt volume, site of the shunt, and presence of other cardiac conditions. CASE PRESENTATION...
coronary artery perforation is a rare, but potentially serious, complication of percutaneous coronary intervention and is associated with a high incidence of death, q-wave myocardial infarction, and emergency coronary bypass surgery. management is different but requires prompt recognition and treatment. we describe a case of coronary perforation only after guidewire removal and also review the ...
