UNLABELLED Coronary artery bypass graft (CABG) surgery is used to revascularize ischemic myocaydium affected by coronary artery obstruction. Conventional coronary angiography (CCA) is an invasive method used for graft evaluation. Nowadays, in post CABG patients grafts can be assessed noninvasively by using coronary computed tomography angiography (CCTA). AIM To determine the late patency rate...
OBJECTIVES We assessed the usefulness of 64-slice computed tomography coronary angiography (CTCA) to detect or rule out coronary artery disease (CAD) in patients with various estimated pretest probabilities of CAD. BACKGROUND The pretest probability of the presence of CAD may impact the diagnostic performance of CTCA. METHODS Sixty-four-slice CTCA (Sensation 64, Siemens, Forchheim, Germany)...
Congenital abnormalities of coronary arteries are an uncommon cause of sudden cardiac death and are difficult to detect at coronary angiography. We describe two patients with acute coronary syndrome and non-occlusive coronary artery disease in which a 64-multidetector computed tomography (MDCT) coronary angiography showed the presence of a malignant coronary anomaly. Sixty-four-MDCT with the po...
BACKGROUND The main aim of our study was to investigate the influence of calcification on the accuracy of 64-slice computed tomography for identification of significant coronary artery disease. METHODS A contrast-enhanced 64-slice computed tomography was performed prior to invasive coronary angiography in 168 consecutive patients with suspected coronary artery disease. All coronary segments 1...
cardiotoxicity is one of the most important adverse event related to anthracycline therapy and can lead in about 1-5% of cases to the occurrence of heart failure. in a higher percentage of patients treated with these drugs asymptomatic left ventricular dysfunction can occur, so that guidelines recommend a strict clinical and echocardiographic monitoring. however, the occurrence of left ventricu...
