BACKGROUND Coronary artery disease (CAD) screening is required before transcatheter aortic valve implantation (TAVR). Although invasive coronary angiography (CA) remains the gold standard for CAD assessment, computed tomographic CA (CTCA) could be a safe and effective noninvasive alternative for CAD screening in patients undergoing TAVR. METHODS AND RESULTS From November 2007 to May 2013, all...

Vasodilatory responses of segments of large epicardial left coronary artery (CA), small intramyocardial CAs (0.3-1.0 mm), coronary stenoses and CAs filled by collaterals were determined in 34 patients. Measurements were made before and after nitroglycerin (0.4 mg, sublingual) by means of quantitative magnification coronary angiography using photospot film and a calibrated 6-power viewing device...

The present study was carried out to test the feasibility of proximal right coronary artery (RCA) imaging and to detect proximal RCA narrowing and occlusion by 2D and 3D transthoracic echocardiography in comparison to coronary angiography (CA). Standardised 2D and 3D echocardiography were performed prior to CA in 97 patients with sinus rhythm. The following parameters were determined: the longe...

We present the case of a 5-year-old child with coronary complications due to Kawasaki disease; this patient unintentionally underwent both dual-source computed tomography (DSCT) coronary angiography and invasive coronary angiographic examination in 2 months. This case highlights the strong consistency of the results between DSCT coronary angiography and invasive coronary angiography. Compared t...

background: muscle fibers overlying the intramyocardial segment of an epicardial coronary artery are termed myocardial bridge (mb). the aim of this study was to analyze the mid-term outcome of mb and to examine its possible association with angiographic findings and concomitant cardiac pathologies such as hypertrophic cardiomyopathy (hcm).   methods: from a total of 3218 patients admitted for c...

BACKGROUND AND OBJECTIVES There is little information about the relationship between the Doppler flow of the ophthalmic artery (OA) and carotid and coronary atherosclerosis. The aim of the investigation was to assess the clinical usefulness of the Doppler flow of the OA to estimate the severity of carotid and coronary atherosclerosis. SUBJECTS AND METHODS The study was a retrospective analysi...
