Angioplasty Care

Angioplasty Care

A nonsurgical approach to opening coronary vessels narrowed by arteriosclerosis, percutaneous transluminal coronary angioplasty (PTCA) uses a balloon-tipped catheter that’s inserted into a narrowed coronary artery. This procedure, performed in the cardiac catheterization laboratory under local anesthesia, helps restore circulation to the heart, relieving pain caused by angina and myocardial ischemia.

A type of percutaneous coronary intervention, angioplasty, when it can be performed within 90 minutes of the patient’s arrival to the emergency department, is recommended by the American Heart Association as the treatment of choice for managing ST-elevation myocardial infarction (STEMI). When angioplasty is used to treat STEMI, it may be performed with or without stent placement. However, stent placement decreases the risk of target vessel revascularization and may reduce the risk of myocardial reinfarction (MI). Thus, stent placement has become routine during angioplasty in such patients.1,2

Cardiac catheterization usually accompanies PTCA to assess the stenosis and the efficacy of the angioplasty. Catheterization is used as a visual tool to direct the balloon-tipped catheter through the vessel’s area of stenosis. As the balloon is inflated, the plaque is compressed against the vessel wall, allowing coronary blood to flow more freely. (See Performing PTCA.)

PTCA provides an alternative for patients who are poor surgical risks because of chronic medical problems. It’s also useful for patients who have total coronary occlusion, unstable angina, and plaque buildup in several areas and for those with poor left ventricular function. After angioplasty, it’s important to monitor the patient closely for signs and symptoms of coronary spasm, MI, and bleeding at the insertion site.
