Coronary angiography (CAG) was performed on a 78-year-old female patient due to class III angina. A calcified critical obstruction was demonstrated in the right coronary artery (RCA). An attempt at percutaneous transluminal coronary angioplasty (PTCA) failed to dilatate the lesion despite high balloon pressure. In a second attempt the lesion was dilatated with the balloon after implementing a t...

We report a case of late multiple stent fractures following the deployment of sirolimus-eluting stents (SESs) for diffuse right coronary artery (RCA) stenosis. A 44-year-old male with hyperlipidemia was referred to our hospital for acute myocardial infarction (AMI). Percutaneous coronary intervention (PCI) was performed for total occlusion of the proximal segment of the RCA, and 5 SESs were con...

Introduction: The development of contrast enhanced whole heart coronary MR angiography (CMRA) at 3T has shown promising results in clinical studies for the detection of significant coronary artery stenoses. However, the imaging time (~ 9 minutes) and spatial resolution (1.3 × 1.3 × 1.3 mm) remain major limitations. Newly available 32-channel cardiac coils allow greater acceleration factors, and...

A50-year-old man with angina pectoris was hospitalized for coronary angiography. He was diagnosed with angina pectoris from the typical symptom (angina on exercise), positive exercise ECG (depressed ST-T in leads I, aVL, and V1 through V3), and positive exercise Tl single photon emission CT (decreased Tl perfusion in anteroseptal wall on exercise and significant redistribution on the 4-hour del...

A 56 year old man was admitted to our center for further evaluation of typical chest pain of ten months' duration. Selective coronary angiography was done and showed a sewing needle-like foreign body which was lying in very close proximity to the anatomic location of the right coronary artery. At operation two pieces of sewing needles were removed, one from the coronary sinus and the other...

coronary artery anomalies are rare, with their incidence varying from 1 to 5%. angiography is a commonly used modality for the assessment of coronary artery anomalies. based on previous reports, a majority of coronary artery anomalies are of origin or distribution, with separate ostia of the left anterior descending artery and left circumflex artery. coronary artery anomalies may cause myocardi...

BACKGROUND Atherosclerosis is a chronic systemic inflammatory disease. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are systemic inflammatory markers that are correlated with poor cardiovascular outcomes. AIM To explore the relation of NLR and PLR with severity of coronary artery disease (CAD). METHODS The study population consisted of 180 consecutive patients...

AIM Previous studies have reported a 10.2%-22% rate of silent cerebral infarction and a 0.1%-1% rate of symptomatic cerebral infarction after coronary angiography (CAG). However, the risk factors of cerebral infarction after CAG have not been fully elucidated. For this reason, we investigated the incidence and risk factors of CVD complications within 48 h after CAG using magnetic resonance imag...

OBJECTIVE We wanted to evaluate the image quality and diagnostic value of 64-slice dual-source computed tomography (DSCT) coronary angiography in patients with atrial fibrillation (Afib). MATERIALS AND METHODS The coronary arteries of 22 Afib patients seen on DSCT were classified into 15 segments and the imaging quality (excellent, good, moderate and poor) and significant stenoses (≥ 50%) wer...

We report on a 69-year-old woman who demonstrated native coronary artery and grafted vessel spasm following on-pump coronary artery bypass grafting (CABG). Despite intraaortic balloon pump (IABP) insertion, electrocardiogram (ECG) abnormalities did not disappear. Emergency coronary angiography (CAG) was performed. The patient was successfully treated with systemic and intracoronary injection of...
