Wellens' syndrome consists of a history suggestive of an acute coronary syndrome and biphasic or deeply inverted T waves in ECG leads V2-V3. A shortcut review was carried out to establish whether this ECG pattern identifies patients with a critical left anterior descending artery stenosis. Six relevant papers were found. The clinical bottom line is that biphasic T-wave inversion in lead V2-V3 s...

A patient in whom exercise induced reversible ischaemic left anterior fascicular block is reported. Glyceryl trinitrate relieved the fascicular block. Coronary angiography showed a 90% obstruction of the left anterior descending artery. The left anterior fascicular block induced by exercise disappeared after a successful coronary angioplasty.

The information presented comes from a case report concerning a left anterior descending coronary artery aneurysm (CAA). The typical "zig-zag" phenomenon, developed exactly within the segment of the sirolimus-eluting stent (SES), and in the left anterior descending coronary artery (LAD). The patient had a previous history of rheumatoid arthritis. We speculated that the CAA could be related to t...

The purpose of this study was to determine the coronary microvascular sites of autoregulation. The epimyocardial coronary microcirculation was observed through an intravital microscope by stroboscopic epi-illumination in anesthetized open-chest dogs (n = 20). Aortic pressure and heart rate were held constant by an aortic snare and atrial pacing, respectively. Distal pressure of the left anterio...

to evaluate the prognostic significance of clinicopathological measurement in the diagnosis of acute myocardial infarction (mi) in sheep, acute mi was induced by ligation of left anterior descending coronary artery (lad). for this purpose, twenty four healthy sheep were divided into the sham-operated or control group (group i, thoracotomy without mi) and the experimental group (group ii, with m...

Right Coronary Artery (RCA) originating from left anterior descending artery is a very rare congenital coronary artery anomaly. A 66-year-old man presented with hypertension and complaints of exertional chest pain. The angiography was performed. Aortic root angiography showed no coronary ostium originating from the right sinus of valsalva. Right coronary artery was visualized as anomalously ori...

We report the case of a patient with dextrocardia and situs inversus totalis associated with obstructive coronariopathy in the anterior and posterior descending arteries, right coronary artery, first diagonal branch and left marginal branch. The patient underwent coronary artery bypass grafting surgery. This surgery has been rarely reported in literature and we found only one similar case in th...

Coronary angiography and computed tomography angiography in the diagnosis of extrinsic compression of left internal mammary artery A 82-year-old man with a previous coronary artery bypass graft was admitted to our hospital for recurrent and refractory episodes of rest angina with electrocardio-graphic signs of anterior myocardial ischemia. Coronary angiography revealed a three-vessel obstructiv...
