Coronary artery anomalies combined with bicuspid aortic valve are rare but cause perioperative complications if not detected on time. Because anomalous coronary arteries vary with respect to the ostium’s origin and transverse route, the precise anatomy should be identified preoperatively and the procedure modified. We describe a severely stenotic bicuspid aortic valve and anomalous coronary art...
Anatomical variations in relation to coronary artery and its branches will help cardiac surgeons for refining imaging techniques and coronary artery bypass grafting. A heart was detected with multiple anomalies of coronary arteries in a cadaver. The anomalies of coronary arteries in terms of origin, number of ostia, courses, and presence of myocardial bridges were described, and related clinica...
INTRODUCTION Coronary artery anomalies are found in 0.4% to 1.4% of patients who undergo coronary angiography. Anomalous origin of left coronary artery from the right sinus of Valsava is the rarest, with a reported prevalence of 0.02 -0.03% according to angiographic studies. CASE PRESENTATION We present the rare case of a 42-year-old-man suffering from stable angina with unusual development o...
Objective To determine whether neutrophil/lymphocyte ratio (NLR) differed between patients with isolated coronary artery disease (CAD), isolated coronary artery ectasia (CAE), coronary slow flow and normal coronary anatomy. Methods Patients who underwent coronary angiography were consecutively enrolled into one of four groups: CAD, coronary slow flow, CAE and normal coronary anatomy. Results Th...
Exclusive dependence on invasive angiography to image coronary artery anatomy is now a thing of the past, thanks to the success of coronary computed tomography angiography (CTA). But evaluation of coronary artery function has remained largely invasive despite the development of cardiac magnetic resonance (CMR) methods to image coronary artery lumens and flow in the 1990s (1,2). Invasive studies...
s: Coronary artery fistula (CAF) is a rare congenital anomaly in which a communication is present between a coronary artery and cardiac chamber. Conventional coronary angiography is an invasive and expensive procedure, and cannot provide three-dimensional data. ECG gated multidetector CT (MDCT) is useful for non-invasive evaluation of coronary artery fistulae. Objectives: In this paper, we desc...
Acute myocardial infarction with normal coronary artery (MINCA) in a patient with multiple sclerosis
Interestingly, some patients with ST elevation myocardial infarction have normal coronary artery anatomy at cooronary angiography. This situation is called as MINCA (acute myocardial infarction with normal coronary artery). The incidence of MINCA varies between 1.0% and 8.5%. Although some reasons have been propounded, the exact underlying mechanism remains unclear. Nevertheless, thoracic myeli...
A 55-year-old female without a history of coronary artery disease, hypertensive for the past 17 years, was admitted with resting chest pain. Electrocardiography revealed a negative T-wave in anterior chest leads. Coronary angiography visualised anomalous coronary anatomy, with a common origin of the right coronary artery and the left main coronary artery in the right sinus of Valsalva serving a...
The presence of only a single coronary artery is a rare congenital coronary artery anomaly. In most cases, it is an incidental finding on coronary angiography and has no clinical significance. However, it can cause angina, myocardial infarction or even sudden death, particularly in young patients in whom the course of the artery runs between the aorta and pulmonary artery. In such cases, angiog...
INTRODUCTION Coronary artery anomalies are found in 0.6% to 1.55% of patients who undergo coronary angiography, and the increasing use of diagnostic coronary angiography is uncovering even more such abnormalities. We present a very unusual case of an anomalous origin of the left circumflex coronary artery (LCx) from the proximal right coronary artery (RCA). CASE PRESENTATION We present a case...
