A 79-year-old male patient with chronic atrial fibrillation and a history of mitral valve repair including ring annuloplasty several years ago underwent coronary angiography (fig. 1) for acute coronary syndrome, which showed the culprit lesion in the proximal left circumflex (LCx) artery. Angiography also showed a branch that arose just proximal to the culprit lesion, coursed on the left and th...

results prediction of the rca as culprit lesion using tierala's algorithm was 86% sensitive and 50% specific. prediction of lcx occlusion based on st-elevation ≥ 1 mm in v6 was 87% specific (p = 0.005). sum of st elevation in leads v5 and v6 more than 2.5 mm, was a good marker of lcx prediction (p = 0.044). st-elevation in v4r was 48% sensitive and 89% specific for rca prediction (p = 0.004). w...

The study by De Luca et al. (1) elegantly demonstrates that increasing doses of intracoronary adenosine are associated with incremental reductions in fractional flow reserve. We would like to caution, however, against high-dose intracoronary adenosine administration in the right coronary artery. Although none of the 12 patients who underwent right coronary artery evaluation in the present study...

Coronary angiography is defined as the radiographic visualization of the coronary vessels after the injection of radiopaque contrast media. The radiographic images are permanently recorded for future review with either 35 mm cine film or digital recording. Percutaneous or cutdown techniques, usually from the femoral or brachial artery, are used for insertion of special intravascular catheters. ...

The prevalence of anomalous coronary artery is approximately 0.6-1.7% in patients who undergo coronary angiography. These anomalies may cause angina, acute myocardial infarction, syncope and sudden death. Cocaine abuse is now a major health hazard: more than 5 million of Americans are current users. Cocaine abuse can result in coronary artery vasocostriction and the association between cocaine ...

OBJECTIVES This study sought to determine whether the location of coronary spastic activity may change over time in patients with persistent variant angina. BACKGROUND Although electrocardiographic studies have provided indirect evidence to indicate that the location of ischemia may change in patients with variant angina, it has not been tested by quantitative angiography whether the location...

The case of a calcified left ventricular aneurysm in a 6-year-old asymptomatic boy is presented. The anomaly was discovered on a routine chest X-ray. The etiology of this condition is discussed. A review of the literature reveals that this is a rare occurrence in children and that the origin is often unknown. Selective left coronary arteriography showed no arterial anomalies but early filling o...

Coronary angiography was performed in i6 patients with a primary myocardial disease, Bantu cardiomyopathy. Two patients had discrete coronary occlusion, presumed embolic from ventricular mural thrombus. There was no evidence of coronary atheroma and all the vessels and their proximal intramural branches were large. The total cross-sectional area of the proximal coronary arteries correlated with...

Background. We tested the prevalence and impact of HCV seropositivity among Egyptian patients referred for coronary angiography. Subjects and Methods. This cross-sectional study was conducted in Zagazig University hospitals including 509 patients scheduled for elective coronary angiography between June 2013 and June 2014. By taking full history on admission, laboratory workup including HCV Ab, ...
