an 80-year-old diabetic man with severe aortic stenosis was admitted to our hospital for cardiogenic shock complicating non-st-elevation myocardial infarction. echocardiographic evaluation showed also a severe degree of both left ventricular dysfunction and mitral regurgitation. the patient was initially stabilized with inotropes and mechanical ventilation was necessary because of concurrent pu...

A total of 32 (3.6%) patients of 880 undergoing coronary angioplasty during a nine year period at one hospital had extensive dissection (defined as a dissection extending beyond the limits of the dilated angioplasty balloon) in the coronary artery in which the angioplasty procedure was performed. Two (6.25%) of the 32 patients (both of whom were undergoing angioplasty because of unstable angina...

Introduction: Coronary angiography and angioplasty procedures lead to significant radiation exposure of patients. In the current study, the average radiation dose to patients during angiography in the Angiography Department of Shahid-Madani Hospital was determined. Materials and Methods: An image intensifier based angiography unit (Philips BH 3000) was used for angiography procedures. The accur...

To examine the cardiovascular adaptations and functional capacity (6 min walk test, rate of perceived exertion, resting heart rate, maximal systolic diastolic blood pressure, mean arterial pressure) by giving Aerobic Exercises in Post Percutaneous Transluminal Coronary Angioplasty patients. The need for study is to know efficiency aerobic exercises post percutaneous transluminal coronary angiop...

Coronary dissection occurs frequently and in several degrees during coronary angioplasty, which is one of the mechanisms for increasing the lumen diameter of a vessel. However the length of the dissection may affect the procedure, becoming the most frequent cause of total occlusion after coronary angioplasty. We report here a case of extensive dissection that occurred during the coronary angiop...

case presentation we present a case of a grade iii coronary perforation in which the double guiding catheter technique helped us to deliver the graft stent. conclusions the double-guiding technique is useful in emergency situations to increase the safety and efficacy of sealing a coronary perforation. introduction coronary vessel perforation is one of the most feared complications of coronary a...

Operator radiation exposure during percutaneous transluminal coronary angioplasty as compared with that during routine coronary angiography is unknown. Therefore, cumulative radiation exposure at operator eye level was measured in two physicians (operators 1 and 2) during performance of coronary angioplasty and routine coronary angiography. The physicians participated together during angioplast...

OBJECTIVES Coronary lumen changes during and after excimer laser-assisted balloon angioplasty were measured by quantitative coronary angiography, and the results were compared with the effects of balloon angioplasty alone. BACKGROUND Reduction of atherosclerotic tissue mass by laser ablation in the treatment of coronary artery disease may be more effective in enlarging the lumen than balloon ...

The incidence of coronary artery spasm at the site of previous successful angioplasty and its importance in leading to subsequent restenosis or recurrence of symptoms are unknown. Fourteen consecutive patients with single vessel coronary artery disease who had undergone successful percutaneous transluminal angioplasty were studied. All patients were given ergometrine maleate (ergonovine maleate...
