OBJECTIVE To evaluate the short and long-term results of percutaneous coronary interventions (PCI) in patients aged 80 years or older and to identify predictors of event-free survival. METHODS AND RESULTS Clinical and angiographic data from all patients undergoing percutaneous coronary intervention in our institution are prospectively collected and stored in a computerized database. The clini...

Coronary artery fistula (CAF) is described as an anomalous connection between a coronary artery and a major vessel or cardiac chamber. It can result in myocardial ischemia, heart failure, pulmonary hypertension, bacterial endocarditis, and rupture of aneurysmal vessels [1]. The majority of these fistulae originate from the left anterior descending artery or from the right coronary artery [2]. S...

We report a case of a postinfarction ventricular septal defect caused by an acute recurrent occlusion after the implantation of a covered stent, which was performed as a rescue procedure for the ruptured left anterior descending artery during a percutaneous coronary intervention. Although the emergent implantation of a covered stent for the ruptured coronary arteries such as the left main coron...

The aim of this present study was to investigate the effects of training on exercise tolerance of patients with coronary heart disease after percutaneous coronary intervention. Fifty-seven cases of coronary heart disease after percutaneous coronary intervention were divided randomly into the rehabilitation training group (26 cases) and control group (31 cases). Patients in the rehabilitation tr...

BACKGROUND Administration of abciximab during primary percutaneous coronary intervention is an effective adjunctive therapy in the treatment of patients with ST-segment elevation myocardial infarction. Recent small-scaled studies have suggested that intracoronary administration of abciximab during primary percutaneous coronary intervention is superior to conventional intravenous administration....

Background: It has been estimated that nearly one-fifth post-percutaneous coronary intervention (PCI) patients treated with clopidogrel continued to have recurrent thrombotic events, which implied the limitation of “one-size-fits all” strategy for antiplatelet therapy.

To study the resistance to standard dosage of clopidogrel among Iranian patients following percutaneous coronary intervention measured by platelet aggregation test.Patients undergoing percutaneous coronary intervention in Imam Hussein Medical center, Tehran, Iran, who were under treatment with aspirin, but had no history of clopidogrel usage, entered the study. Patients received standard dosage...

A 48-year-old male patient diagnosed with Kawasaki disease in childhood presented with recurrent angina after undergoing coronary artery bypass surgery in 1996. Percutaneous transluminal coronary angioplasty and intracoronary stent placement to a lesion in the proximal ramus intermedius were performed successfully. This case illustrates the complementary nature of percutaneous and surgical myoc...
