P ercutaneous transluminal angioplasty is an accepted treatment for stenoses of bypass graft& and for total coronary artery occlusions.3-5 It follows that the same treatment would also be appropriate for total occlusions of saphenous aortocoronary bypass grafts. This report describes our clinical experience with attempted dilatation of totally occluded saphenous bypass grafts. Of the 2,679 cons...

We describe a case of 70 years old female patient in whom an initial diagnosis acute coronary syndrome (ACS) revealed to be finally aortic dissection. This report emphasizes the importance maintain high grade suspicion dissection as possible alternative presence electrocardiographic myocardial ischemic changes. In many medical centers where thrombolytic therapy, antiplatelet receptor blockers, ...

Two years after an orthotopic cardiac transplant a 28 year old man was found to have clinically significant stenosis of the right coronary artery at routine coronary angiography. This lesion was accompanied by a perfusion defect on exercise thallium scintigraphy. Percutaneous transluminal coronary angioplasty of the lesion improved the angiographic appearance of the stenosis and reduced the exe...

Myocardial infarction is rare in pregnancy. A 30 year old white primigravida had an anterior infarct at 20 weeks' gestation, which was followed by troublesome angina. Coronary angiography showed a tight stenosis of the left anterior descending coronary artery. This was treated successfully by percutaneous transluminal coronary angioplasty.

Heparin has been used to prevent intravascular thrombosis and clotting on the surface of equipment used during percutaneous coronary interventions (PCI) since Andreas Gruentzig performed the first angioplasty. In fact, the development of coronary angioplasty and of coronary artery bypass surgery would probably not have been possible without heparin. However, with the availability of low molecul...

BACKGROUND Percutaneous transluminal coronary angioplasty of the infarct-related artery in stable survivors of acute myocardial infarction is often performed, even in patients without any symptoms or residual ischemia. Despite the lack of randomized studies, it is widely believed that this intervention will improve the clinical outcome of these patients. METHODS AND RESULTS Three hundred pati...

conclusions music therapy is a safe, simple, inexpensive, and non-invasive nursing intervention, which can significantly alleviate patients’ anxiety during coronary angioplasty. patients and methods this was a randomized controlled trial, conducted in the catheterization laboratory unit of baqiyatallah hospital, in tehran, iran. a sample of 64 patients, who were planned to undergo coronary angi...

OBJECTIVES We aimed to evaluate the safety and feasibility of a robotic angioplasty system in delivery and manipulation of coronary guidewires, balloons, and stents in patients undergoing elective percutaneous coronary intervention (PCI). BACKGROUND A remote-control, robotic-assisted angioplasty system is under development to address some of the procedural challenges and occupational hazards ...

Coronary stent implantation has significantly improved percutaneous coronary intervention and enabled the management of early complications of plain balloon angioplasty (POBA). By preventing elastic recoil and constrictive remodeling, coronary stent implantation decreases the frequency of restenosis after percutaneous coronary intervention. However, a new complication has accompanied these impr...
