INTRODUCTION The primary diagnostic examination performed in patients with a high pre-test probability of coronary artery disease (CAD) is invasive coronary angiography. Currently, approximately 50% of all invasive coronary angiographies do not end with percutaneous coronary intervention (PCI) because of the absence of significant coronary artery lesions. It is desirable to eliminate such situa...
The relations of high density lipoprotein (HDL) subclasses to severity and rate of progression of coronary atherosclerosis were investigated in 60 men who had survived a myocardial infarction before the age of 45 years and who had subsequently undergone two coronary angjographies, with an intervening time interval of 4-7 years between angiographies. Five HDL subclasses with different particle s...
We present static and dynamic techniques to visualize perfusion data and to relate perfusion data to morphologic image data. In particular, we describe the integrated analysis of MRI myocardial perfusion data with CT coronary angiographies depicting the morphology. We refined the Bull’s-Eye Plot, a wide-spread and accepted analysis tool in cardiac diagnosis, to show aggregated information of pe...
Background: Coronary calcium shows the atherosclerosis burden in coronary arteries and is associated with adverse cardiac events. Agatston score most widely used scoring sys-tem to quantify artery calcium. In this study, we aimed establish factors change time. Materials Methods: Patients who underwent multiple computerized tomo-graphic angiographies had measurements were included study. The of ...
AIMS The purpose of this registry is to collect data on trends in interventional cardiology within Europe. Special interest focuses on relative increases and ratios in newer revascularization approaches and its distribution in different regions in Europe. We report the data of the year 2003 and give an overview of the development of coronary interventions since 1992, when the first data collect...
BACKGROUND Coronary angiography is more complex in patients with coronary artery bypass grafts (CABG). Image fusion is a new technology that allows the overlay of a computed tomography (CT) three-dimension (3D) model with fluoroscopic images in real time. METHODS AND RESULTS This single-center prospective study included 66 previous CABG patients undergoing coronary and bypass graft angiograph...
Coronary artery fistulae are usually identified during invasive coronary angiographies. However, in this case, we made the early detection of coronary artery fistulae during non-invasive transthoracic echocardiography, by demonstrating diastolic multiple abnormal color Doppler flows on the entire left ventricular walls including left ventricular free wall, interventricular septum and apex, whic...
Background. The thrombosis risk is increased in active ulcerative colitis. The limited number of reported complications have predominantly been cerebrovascular but other vessel territories may also be affected. Patient. During a severe attack of ulcerative colitis a 37-year-old woman suffered occlusion of all left coronary artery branches. Serial angiographies showed progressive recanalisation ...
INTRODUCTION The Board of the Association of Cardiovascular Interventions of the Polish Cardiac Society (AISN PTK) publishes annual data from the National PCI Registry (ORPKI) operated by the Jagiellonian University Medical College in Krakow. AIM For the first time the AISN PTK report is based on the new electronic database implemented in Poland on January 1(st), 2014. MATERIAL AND METHODS ...
AIMS High-sensitivity cardiac troponin (hs-cTn) assays provide higher diagnostic accuracy for acute myocardial infarction (AMI) when compared with conventional assays, but may result in increased use of unnecessary coronary angiographies due to their increased detection of cardiomyocyte injury in conditions other than AMI. METHODS AND RESULTS We evaluated the impact of the clinical introducti...
