Cineangiograms of 138 patients who underwent percutaneous transluminal coronary angioplasty (PTCA) were analyzed with a computer-based coronary angiography analysis system. The results before and after dilatation are presented. In a first study group (120 patients), the severity of the obstructive lesions derived from the automatically detected contours was evaluated in absolute terms and in pe...
The cutting balloon (CB) is a specialized device designed to create discrete longitudinal incisions in the atherosclerotic target coronary segment during balloon inflation. Such controlled dilatation theoretically reduces the force needed to dilate an obstructive lesion compared with standard percutaneous transluminal coronary angioplasty (PTCA). We report a multicenter, randomized trial compar...
OBJECTIVE To determine current outcomes of percutaneous transluminal coronary angioplasty (PTCA) and coronary artery bypass grafting (CABG). DESIGN The Scottish coronary revascularisation register provided prospectively collected data on case mix and in-hospital complications for all revascularisation procedures between April 1997 and March 1999 (4775 PTCA; 5115 CABG). Linkage to routine hosp...
Homogeneity of microvascular resistance in different perfusion areas of the same heart is generally assumed. We investigated the effect of the severity of an epicardial stenosis on microvascular resistance in 27 patients with coronary artery disease and stable angina. All patients had an angiographically normal coronary artery, an artery with an intermediate lesion, and an artery with a severe ...
We describe a 54-year-old man who was HIV-positive, admitted for cardiogenic shock complications inferior myocardial infarction. He was treated with primary percutaneous transluminal angioplasty (PCTA) and stent deployment in mid right coronary artery. After a few days thrombotic occlusion of the stent occurred, and the problem recurred during implantation of a new stent in the course of a seco...
Four patients who had stenosis of a single major coronary artery which was treated by percutaneous transluminal coronary angioplasty are described. Three had exercise induced myocardial ischaemia complicated by ventricular tachycardia, fibrillation, and sinus bradycardia, respectively. Asystole developed in a fourth patient who had spontaneous chest pain. After successful percutaneous translumi...
Angina pectoris, cardiac pain associated with ischemia, is considered refractory when optimal anti-anginal therapy fails to resolve symptoms. It is associated with a decreased life expectancy and diminishes the quality of life. Spinal cord stimulation (SCS) may be considered for patients who have also undergone comprehensive interventions, such as coronary artery bypass graft (CABG) and percuta...
methods in this article we checked the derived data from 20 relevant studies published during the last 20 years in international scientific literature at other country except iran and 10 studies from iran. the variables dose-area product (dap), fluoroscopy time, number of sequences and frames per sequence were collected for each ca, ptca, rfa and diagnostic electrophysiology and then the obtain...
OBJECTIVE To assess the safety and feasibility of acute transport followed by rescue percutaneous transluminal coronary angioplasty (PTCA) or primary PTCA in patients with acute myocardial infarction initially admitted to a hospital without PTCA facilities. DESIGN In a multicentre randomised open trial, three regimens of treatment of acute large myocardial infarction were compared for patient...
