BACKGROUND A normal anatomy of coronary arteries is important to have adequate cardiac muscle blood supply especially during extraneous physical activities. This case report describes a rare coronary anomaly in which the accessory coronary artery arose from the right coronary artery, reentered the left anterior descending coronary artery, and then ran as a single vessel. CASE PRESENTATION We ...

Unilateral agenesis of the pulmonary artery is a rare congenital anomaly, which commonly involves the right side. Cases are associated with systemic collaterals, that may also rarely arise from the coronary arteries.Two adult patients are presented with a right pulmonary artery agenesis associated with collaterals from the right coronary artery. The implications of such an anomaly on pulmonary ...

A 34-year-old woman was admitted to the hospital because of recently aggravated right heart failure without angina for 5 months. When she was 25 years old, patch repair with Polytetrafluoroethylene (PTFE) was performed for the secondum type of atrial septal defect (ASD) with moderate pulmonary hypertension. The chest PA, echocardiography and cardiac catheterization at current admission revealed...

Spontaneous coronary artery dissection, which causes acute coronary syndrome and can result in sudden death, is rare; but its true incidence is underestimated, since most patients die suddenly, without diagnosis. The aim of this study was to show the importance of prompt diagnosis and treatment. In reviewing the records of 5,000 consecutive patients who underwent coronary angiography between Ja...

INTRODUCTION The coronary anatomic variation of the left circumflex artery (LCx) is considered as the most common anatomic variation with a separate ostium from the right sinus, and very unusual variation as a proximal branch of right coronary artery (RCA). CASE REPORT We report two cases, the first case is a 64-year-old man with chest pain and with history of hypertension, obesity, dyslipide...

The anomalous origin of the right coronary artery (RCA) as a branch from the left anterior descending artery (LAD) is a very rare variation of the single coronary artery anomaly. The anomalous vessel arises from the proximal or midportion of the LAD and courses anterior to the pulmonary artery trunk in most instances. In this case report, a 61-year-old woman is introduced who underwent coronary...

INTRODUCTION Congenital aomalies of the aortic arch, although numerous and heterogeneous, occur in less than 1% of individuals at autopsies. Left aortic arch with an aberrant right subclavian artery, also called arteria lusoria dextra, is the most common anomaly of the aortic arch, occurring in 0.5-2.5% of individuals. CASE OUTLINE We report the case of a 48-year-old man suffering from acute ...

BACKGROUND Coronary computed tomography angiography (CCTA) is helpful in making a precise noninvasive evaluation of coronary anatomy, allowing concomitant evaluation of other cardiac structures. The aim of this study was to determine the prevalence of coronary artery variations detected by 64-slice multi detector CT. MATERIALS AND METHODS The results of ECG-gated CCTA in 726 consecutive patie...

A single coronary artery is an anomaly in which only 1 coronary artery arises from the aortic root, supplying the entire heart. We report the case of a 5-year-old girl in whom a single coronary artery ostium was discovered during a Ross-Konno operation. This patient required extracorporeal membrane oxygenation for postoperative right ventricular infarction due to proximal stenosis of a dominant...
