origination of the right coronary artery (rca) from the left anterior descending (lad) artery is a case of single coronary artery. it is an extremely rare coronary artery abnormality and usually an incidental finding during coronary angiography. a 73-year-old man with a medical history of hypertension arrived with chest pain. medical therapy started for st elevated myocardial ischemia. during h...

BACKGROUND/AIMS Many studies have investigated angina and its relationship with chronic obstructive pulmonary disease (COPD). However, angina was diagnosed only by noninvasive tests or only by clinical symptoms in most of these studies. The aim of this study was to compare the prognosis, including rate of hospitalization and death from significant coronary artery lesion and nonsignificant coron...

BACKGROUND The usefulness of thin-slice multi-detector computed tomography (MDCT) has been highly expected to assess the lumens of coronary artery stents. We evaluated the usefulness of 16-slice MDCT to assess the in-stent lumen after coronary artery stenting. METHODS In 42 consecutive patients after coronary artery stenting, retrospective ECG-gated CT-angiography using 16-slice MDCT (0.5-s r...

BACKGROUND Coronary artery bypass grafting (CABG) with a composite Y-graft made of the left internal thoracic artery (LITA) and another arterial graft has a risk for hypoperfusion. Changes over time in the diameter of the LITA anastomosed to the left anterior descending coronary artery (LAD) are not known. METHODS Data were collected for 71 patients who had undergone coronary angiography (CAG...

iatrogenic coronary artery dissection during coronary angiography with or without rupture is a rare but feared complication . we herein report a case of iatrogenic left main coronary artery dissection in a 49-year-old female. admitted to our hospital with a recent history of severe hypotension, she develpled apnea during angiography. she was intubated  and resuscitated with an epinephrine infus...

Spontaneous coronary artery dissection (SCAD) is rare, but it frequently presents as acute myocardial infarction. It is frequently fatal and most cases are diagnosed at autopsy. We herein present the case of a 65-year-old woman with ST-elevation and myocardial infarction due to SCAD. Optical coherence tomography (OCT) helped us to confirm the diagnosis. The information on the intravascular morp...

A 55 year-old man was admitted to the hospital with typical chest pain; the ECG and cardiac biomarkers were normal. He had a history of hypertension and coronary angiography (CAG) a year ago due to unstable angina pectoris and a drugeluting stent was implanted at the left anterior descending (LAD) coronary artery. CAG was performed at admission due to persistent chest pain and a single right co...

Abstract Background Atherosclerosis is a systemic arterial disease with heterogeneous involvement in all vascular beds, however studies examining the relationship between coronary and radial artery calcification are lacking. The purpose of this study was to assess two sites prognostic value (RC) for disease. Methods results This single-center, retrospective cross-sectional based on doppler ultr...
