We describe a case in which the guide wire penetrated through the left anterior descending artery into the left ventricular cavity during percutaneous transluminal coronary angioplasty. This complication of coronary angioplasty which had not been previously reported was suspected because of the characteristic motion of the guide wire on the X-ray image and was confirmed by echocardiography.

band, increasing from less than 1,000 per year in 1979–1981 to more than 300,000 per year in 1991. This was similar to the annual number of bypass operations . The number of annual catheterizations has now grown to approximately 1.4 million, with one of three patients who undergo diagnostic cardiac catheterization being referred for coronary angioplasty, compared with one of four being referred...

The coronary steal syndrome is an uncommon but well recognised occurrence following coronary artery by-pass surgery using the internal mammary artery. We report a case of coronary steal successfully treated with percutaneous transluminal angioplasty of a subclavian stenosis.

Background: Practice of interventional cardiology procedures such as Coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA) has largely increased in recent years and is now changing to a matter of routine in many hospitals. The purpose of this study was to measure skin and organ doses in patients undergoing CA and PTCA and to find a probable relation with c...

Percutaneous coronary intervention (PCI) using balloon angioplasty with stenting has become a mainstay in the treatment of patients with coronary artery disease (CAD). Over one million PCI procedures were performed in the U.S. alone in 2000, nearly one-half of which involved placement of a coronary stent (1). This number is expected to increase as more revascularization procedures that were pre...

Over the last three decades, percutaneous coronary intervention (PCI) technology has revolutionized the field of cardiology. PCI began in the form of balloon angioplasty, and was followed by coronary stenting. In-Stent restenosis is the main limitation of coronary stenting, and has been delayed to some extent by the development of drug eluting stents. Coronary angioplasty with stenting is curre...

background: the number of interventional cardiology (ic) procedures has increased rapidly. coronary angiography (ca) and percutaneous transluminal coronary angioplasty (ptca) are now widely performed as a matter of routine, and they are considered safe procedures for experienced cardiologists. however, it is also known that these procedures are associated with high radiation doses due to long f...

Introduction: Ischemic preconditioning mediated by potassium channels is a physiological protective mechanism, . It is hypothesized that Nicorandil, which is a potassium channel activator, could protect the heart via preconditioning. Materials and Methods:This clinical trial was conducted on 162 patients undergoing percutaneous coronary intervention (PCI) in Quem hospital, from Jan2013 to Jan 2...
