cor triatriatum   sinistrum is a rare congenital cardiac malformation, accounting for about 0.1-0.4% of all congenital heart diseases and characterized by the presence of a fibromuscular membrane that subdivides the left atrium into two chambers in the classical form. while classic cor triatriatum in most patients can be observed during the neonatal period or early infancy, it is very rare in a...

Figure 1: (A) Angiographic left anterior oblique view showing the anterior descending artery originating from the sinus node artery (SNA), between the aorta and the superior vena cava. (B) Right anterior oblique view. In contrast to the classical anomalous origin from the right coronary artery, where the anterior descending artery crosses de infundibulum anteriorly, in this case the anterior de...

A 76-year-old woman underwent coronary angiography for chest pain. On the coronary angiogram, no significant coronary artery atherosclerotic stenosis was observed. Multiple coronary artery microfistulas, draining from the left anterior descending artery to the left ventricle and from the posterior descending artery of the right coronary artery to the left ventricle, were observed. Apical wall t...

​Congenital anomalies of the coronary arteries have been a known subject  since the advent of cardiac angiography, and has been a subject of special interest by both cardiologists and cardiac surgeons,  We have tried in this article to present a case of anomalous origin of LAD from RCA (RMT) in a 55 year old lady (Mrs. B.J.) and to completely dis­cuss this subject. It's worthmentioning that thi...

traumatic coronary artery-cameral fistulas (tcaf) are rare and may present secondary to penetrating injuries (80%) or iatrogenic traumas. early operative intervention remains the recommended treatment modality for accidental traumatic coronary artery fistulas. we report the case of a 17-year-old man who presented with left anterior descending coronary artery-right ventricle fistula following pe...

Several methods have been used to measure left ventricular regional blood flow in humans. However, limitations and lack of validation in patients are major problems. A continuous thermodilution technique to measure regional left ventricular blood flow in patients with coronary disease was validated in vivo. This technique permits simultaneous assessment of venous blood flow draining predominant...

The purpose of this study was to determine the coronary angiographic correlations (specifically disease of the left anterior descending coronary artery) of reciprocal ST segment depression appearing during inferior acute myocardial infarction. Forty six patients (41 men and five women; mean age 56 years) were allocated into two groups based on the extent of precordial ST segment depression: wid...

The predictive accuracy of exercise thallium-201 (201Tl) myocardial scintigraphy in the evaluation of aortocoronary bypass graft surgery was assessed in 48 patients undergoing angiographic investigation 15 months (mean time) after myocardial revascularisation. 201Tl scintigrams detected 61 out of 77 (79%) patent grafts but only 21 out of 42 (50%) occluded grafts, though, for grafts supplying no...

to lack of improvement, she was transferred for rescue percutaneous coronary intervention. Successful percutaneous coronary intervention was performed on the left anterior descending artery, although persisting slow flow was noted (Figs. 1B and 1C, Online Video 1). Diffuse narrowing of the distal left anterior descending artery was also observed, suggesting external compression of the vessel. T...
