background: the purpose of this study was to evaluate the infl uence of ejection fraction (ef) on peak aortic time (pat) and  peak aortic enhancement (pae) during coronary computed tomography angiography (cta). materials and methods: one-hundred and twenty patients (64 men, 56 women) underwent measurement of coronary cta with a measurement of ef within 3 months of coronary cta.pearson’s correla...

BACKGROUND Spontaneous coronary artery dissection is an uncommon syndrome. Its prevalence among patients with polycystic kidney disease is very rare, with no previously reported involvement of the right posterior descending coronary artery. CASE PRESENTATION We describe the case of a middle-aged Caucasian woman with polycystic kidney disease who presented with a non-ST elevation myocardial in...

For the success of anatomical correction of transposition of the great arteries (TGA) it is essential to transfer the coronary ostia to the posterior vessel without undue tension, torsion, or kinking of the proximal coronary arteries or their early branches. This requires thorough understanding of the different modes of origin and early branching of the coronary arteries in TGA. Based on observ...

We report a case of 53-year-old male admitted to the hospital with severe chest pain and elevation of troponin I levels, who was transferred to our department for a coronary angiography. Contrast injection into the right coronary artery (RCA) demonstrated no evidence of coronary artery disease. However, a double outlet coronary artery fistula which drained into the right ventricle was visualise...

Some of coronary artery anomalies, such as origin of all coronary arteries from three separate ostiums in the right sinus of valsalva, represent a small amount of coronary anomalies. We describe a 63-year-old female patient which coronary angiogram revealed an origin of all coronary arteries from three separate ostiums in the right sinus of valsalva, with significant atherosclerotic plaque at t...

artery occlusion caused no change in cardiac output, or right and left ventricular pressures, although right ventricular contractile force fell markedly. With right coronary artery flow intact, incremental pulmonary artery obstruction caused a corresponding decline in cardiac output and elevation of right ventricular end-diastolic pressure with eventual total right ventricular failure and syste...

We successfully treated chronic type A dissection and coronary artery disease with a functional midline crossing right internal thoracic artery (RITA) after coronary artery bypass grafting (CABG). A 68-year-old man was incidentally diagnosed as chronic type A dissection by follow-up cardiac catheterization after CABG, with 90% stenosis in the right coronary artery (RCA) No. 2. The dissecting an...

1 of 2 DESCRIPTION A murmur was noted in a 2-year-old patient who was otherwise asymptomatic. The patient was born by caesarean section at 37 weeks gestation. No signifi cant family history was present. Clinical examination revealed a continuous murmur at the sternal edge. Echocardiography did not reveal any abnormality. Cardiac catheterisation revealed a communication between the right coronar...

Coronary stent fracture is an uncommon complication of stent implantation. We report a case of 66 yrs old male patient presented with unstable angina who underwent stenting in right coronary artery 3 months ago. Computed Tomography Coronary angiogram revealed complete type V stent fracture with pseudoaneurysm formation in right coronary artery. This was managed by surgical revascularization by ...
