A major coronary artery crossing the right ventricular outflow tract in patients with tetralogy of Fallot interferes with a transannular patch, and preoperative detection of this artery is important. We evaluated the ability of two-dimensional echocardiography to define noninvasively the coronary artery anatomy in 37 consecutive patients (age range, 1 day to 18 years; mean age, 40.9 months). Th...

Spontaneous coronary artery dissection is rare and usually affects younger women in the peripartum period. Here, we report an interesting case of a 34-year-old woman with spontaneous coronary artery dissection that occurred 1 month after childbirth. Emergency coronary angiography showed stenosis of the left anterior descending artery, but immediately afterwards, a new occlusion of the right cor...

conclusions routine predilation of the sb in provisional stenting of true bifurcation lesions seems to be ineffective and might be associated with some undesirable consequences. still, there are some complex ostial lesions of the sb which could benefit from predilation. patients and methods sixty patients with true bifurcation lesions according to the medina classification were included in the ...

purpose: to assess the relationship between the severity of coronary arteries involvement and the extent and pattern of myocardial scars in cardiac magnetic resonance of patients with history of remote myocardial infarction. materials and methods: the cardiac magnetic resonance images of sixty patients with history of remote st segment or non-st segment elevation myocardial infarction were revi...

INTRODUCTION Anomalous origin of coronary arteries from opposite sinus of Valsalva is rare finding. The incidence of anomalous origination of the left coronary artery from right sinus is 0.15% and the right coronary artery from the left sinus is 0.92%. The ectopic origin of left coronary artery or right coronary artery from opposite sinus depending on pathways and considering atherosclerotic ch...

PURPOSE Myocardial infarction in children with total occlusion of a coronary artery after Kawasaki disease is rare due to multiple collateral vessels. We aimed to investigate the changes in coronary perfusion associated with coronary artery occlusion after Kawasaki disease. MATERIALS AND METHODS Eleven patients with coronary artery occlusion after Kawasaki disease were investigated. Serial co...

a double left anterior descending (lad) coronary artery emerging from the left and right coronary arteries is classified among rare coronary anomalies. we herein report a 73-year-old man presenting with acute coronary syndrome (posterolateral myocardial infarction). he was admitted with typical chest pain, and due to his progressive ischemic changes on electrocardiography (ecg) and elevated car...
