Radiography and Interventional Radiology : Radiography of Percutaneous Transluminal Coronary Angioplasty

Percutaneous transluminal coronary angioplasty.

Percutaneous transluminal coronary angioplasty (PTCA) is a nonoperative mechanical dilatation of atherosclerotic coronary artery stenosis by a balloon-tipped dilating catheter system. This method can effectively reduce highly stenotic coronary lesions and provide early recovery of ischemic but viable myocardium. The technique of transluminal angioplasty was originally devised by Dotter and Judk...

Assessment of patients skin dose undergoing coronary angiography and Percutaneous Transluminal Coronary Angioplasty (PTCA)

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 transluminal coronary angioplasty.

[Percutaneous transluminal coronary angioplasty (PTCA)].

In 1959, Dr. Mason Sones reported on selective coronary arteriography, a technique that quickly became the standard for precise diagnosis of coronary artery disease. In the early 1960s Drs. Dotter and Judkins introduced the original concept of using a catheter to dilate an atherosclerotic obstruction in a peripheral artery. Now, almost 2 decades later, the selective coronary catheter is being p...

Percutaneous Transluminal Coronary Angioplasty Registry

In 1,801 patients in the 1985-1986 Percutaneous Transluminal Coronary Angioplasty Registry, overall 1-year mortality was 3.2%, the 1-year myocardial infarction rate was 7.2%, and the l-year coronary artery bypass surgery rate was 13.2%. In the 78% of the cohort with all lesions successfully dilated and without major procedural complications (successful patients), the corresponding rates were 1....
