Twelve years after receiving a renal transplant, a 50-year-old woman developed asthmatic symptoms. Chest CT revealed a descending thoracic aortic aneurysm. She had undergone percutaneous coronary intervention to treat the left anterior descending artery 10 years earlier. Coronary artery angiography revealed restenosis of the left anterior descending artery (99%, #6 in-stent). Because cardiopulm...

OBJECTIVE To perform a comparative assessment of two surgical techniques that are used creating an acute myocardial infarc by occluding the left anterior descending coronary artery in order to generate rats with a left ventricular ejection fraction of less than 40%. METHODS The study was completely randomized and comprised 89 halothane-anaesthetised rats, which were divided into three groups....

BACKGROUND Coronary arteries originating from the right coronary ostium in the ascending aorta represent a very rare anatomic presentation. Also, the presence of a single coronary ostium is an extremely rare finding. CASE PRESENTATION We present the case of a 74-year-old Albanian man from Kosovo. He had unstable angina due to critical triple vessel disease and a single coronary artery origina...

One hundred and eight patients with single and multiple vessel coronary artery disease confirmed by arteriography were evaluated by exercise thallium-201 (201Tl) myocardial scintigraphy to determine the scintigraphic appearances of specific coronary stenoses. In general proximal stenoses caused more widespread, but not necessarily more severe, myocardial tracer deficit than distal stenoses. In ...

Abstract Background Index of microcirculatory resistance (IMR) has been used as a clinical measure microvascular function. Transthoracic Doppler echocardiography (TDE) can provide information on the functional status coronary artery circulation. This study aims to assess diagnostic value left-anterior-descending (LAD) flow velocity by TDE for dysfunction. Methods Consecutive patients who were s...

Introduction: Although left anterior descending (LAD) artery supplies a large portion of the myocardium, the amount of blood supply provided by LAD is depended on the length of the LAD. The aim of the current study was to evaluate the association between coronary artery dominance and LAD anatomic types in patients with normal epicardial coronary arteries. Methods:...
