[en] The QRS-T maps constructed from the simultaneous recording of 120 thoracic leads were displayed at intervals of 10 msec on a X-Y plotter after processing of the data by computer. A series of 25 ostensibly normal subjects and 25 patients with coronary artery diseases (CAD) but normal resting ECG were investigated. The results were compared with those of exercise myocardial scintigraphy. As most salient features we observed that mapping images at rest demonstrated abnormal negative ST areas in 5/25 patients with CAD, while the mapping images recorded during exercise were abnormal in 21 out of the 25 patients with CAD, instead of only 15 out of these 25 patients when classical criteria determined on the conventional ECG leads for exercise ECG monitoring (V2-4-6, aVF) were used
[en] Coronary artery perforation remains one of the most fearsome complications during cardiac catheterization procedures. Although emergent bypass surgery is the preferred treatment for cases with uncontrollable perforation, endovascular vessel sealing and arrest of bleeding with a combination of balloons, covered stents, or embolic materials have also been proposed. The authors describe a case of emergent lifesaving microcoil embolization of the distal right coronary artery in a patient with uncontrollable grade III guidewire perforation resulting in cardiac tamponade. The relevant literature is reviewed and the merits and limitations of the endovascular approach are highlighted.
[en] We report a case of an anomalous course of the right coronary artery (RCA) through the right atrium, which was evaluated using dual-source CT angiography. There have been a few cases described previously in literature, but most of them were found either during surgery or at autopsy. Although this variant is clinically benign, it has significant consequences during interventional procedures or bypass surgery
[en] The first objective of this study was to investigate whether changes have accurred in the native coronary arteries which have been bypassed. The graft patency related to several factors was also evaluated. The second objective was to investigate what factors are of influence in relation to the difference in graft patency, found in two groups of patients operated upon whereby for each group of patients a different operation technique has been used. To investigate the availability of the computer data analysis, designed for this study, was the third objective. Left ventricle evaluation, post-operatively, has been carried out. Several chapters are devoted to the anatomy, haemodynamics, coronary angiography and radiological aspects, in order to create a short manual for the radiologist, interested in cardiology.

[en] A coronary cameral fistula (CCF) involves a sizable communication between a coronary artery and a cardiac chamber. We present a case of giant coronary cameral fistula associated with coarctation of aorta in a 13 days old neonate
