conclusions: patent coronaries of ua/nstemi patients have a trend to higher tfcs compared to normal values. presence of significant coronary lesions in these patients significantly increases tfc. objectives: the present study is aimed to measure the tfc in the coronary arteries of ua/nstemi patients to find abnormalities in diseased or patent vessels and compare with the normal values. patients...

Embolic occlusion of the peripheral vessels is common in bacterial endocarditis, especially during the terminal stages, but occlusion of the coronary artery in this disease is unusual at any time. Virchow (1856) described coronary embolism in a case of recent endocarditis. Saphir (1933) surveying earlier reports of coronary embolism from all causes, found 35 cases reported since Virchow's origi...

The aim of this study was provide a description of the macroscopic heart anatomy of the kangaroo Macropus fuliginosus. The terms of the Nomina Anatomica Veterinaria were employed. Heart did not have interventricular sulcus. Auricles were located in both faces of the heart. Right ventricle had slight septomarginal trabecula that extended between papilar muscles and the parietal wall. Right ventr...

This is the case of an 18 year old active duty soldier with symptoms of exertional chest pressure and syncope who was found to have anomalous origin of the left main coronary artery (LMCA) from the right coronary cusp (RCC) traveling partially between the great vessels before taking a septal approach between the left ventricular outflow tract (LVOT) and the right ventricular outflow tract (RVOT...

Coronary artery ®stula is a rare congenital malformation that can be complicated by intracardiac shunts, endocarditis, myocardial infarction, coronary aneurysm and sudden death. Clinical symptomatology depends upon the underlying anatomy and the size of the ®stulous connection between the left or right side of the heart. We report the successful management of a giant right coronary artery with ...

Tlie collateral vessels of normal and pathologic hearts were studied by making plastic casts of the coronary vessels. The normul heart possesses conspicuous coronary anastomoses. The localization, the development and to a certain extent, the incidence was studied. The maximum increase in collateral vessels was observed in cases of coronary narrowing; a less pronounced increase was found in cond...

BACKGROUND The anatomical variants of the relations of the left circumflex artery (LCx) andthe coronary sinus (CS) determine the safety of percutaneous mitral annuloplasty (PMA) as an occlusion of the LCx and its consequences might occur in some cases. Thus, knowledge ofthe anatomy of cardiac anatomy and any variations are important for surgeons. METHODS In 320 (126 women, age 59 ± 11) patien...

OBJECTIVE To evaluate different characteristics of patients with acute coronary syndrome (ACS) without ST-segment elevation compared with transient St-segment elevation. DESIGN An observational, prospective study. SETTING A 12-bed coronary care unit. PATIENTS Consecutive patients of ACS without persistent ST-segment elevation. MAIN VARIABLES OF INTEREST The population was divided intro ...

BACKGROUND Multi-detector spiral computed tomography with retrospective electrocardiography-gated image reconstruction allows detailed anatomic imaging of the heart, great vessels and coronary arteries in a rapid, available and non-invasive mode. OBJECTIVES To investigate the spectrum of findings in 32 consecutive patients with chest pain who underwent CT coronary angiogram in order to determ...
