Percutaneous coronary intervention (PCI) is a minimally invasive non-surgical procedure used to treat narrowing of the coronary arteries of the heart found in coronary artery disease. [2] The procedure is used to place and deploy coronary stents , a permanent wire-meshed tube, to open narrowed coronary arteries.
Coronary CT angiography (CTA or CCTA) is the use of computed tomography (CT) angiography to assess the coronary arteries of the heart.The patient receives an intravenous injection of radiocontrast and then the heart is scanned using a high speed CT scanner, allowing physicians to assess the extent of occlusion in the coronary arteries, usually in order to diagnose coronary artery disease.
A percutaneous coronary intervention (PCI), or coronary angioplasty with stenting, is a non-surgical procedure used to improve the blood flow to the heart. [1] Coronary angioplasty is indicated for coronary artery diseases such as unstable angina, NSTEMI, STEMI and spontaneous coronary artery perforation. [1]
The most accurate ways to detect CAD are the coronary angiogram and the coronary CT angiography. [4] An angiogram can provide detailed anatomy of coronary circulation and lesions. The significance of each lesion is determined by the diameter loss. A diameter loss of 50% translates to a 75% cross-sectional area loss, considered moderate by most ...
Coronary angiography and angioplasty in acute myocardial infarction (left: Right Coronary Artery [RCA] closed, right: successfully dilated) Interventional cardiology is a branch of cardiology that deals specifically with the catheter based treatment of structural heart diseases.
The use of a coronary angioplasty to abort a myocardial infarction is preceded by a primary percutaneous coronary intervention. The goal of a prompt angioplasty is to open the artery as soon as possible, and preferably within 90 minutes of the patient presenting to the emergency room. This time is referred to as the door-to-balloon time.
Less pain for the patient and quicker recovery time. Particularly in high risk patients, morbidity and mortality decreases in comparison to conventional surgery. [ 2 ] [ 3 ] A study from FuWai Hospital in Beijing [ 4 ] reports on 104 patients with multivessel coronary artery disease who were compared with the same sized group of patients ...
Imaging in coronary angiograms is performed via fluoroscopy using X-rays, which pose a potential for increasing the patient's risk of radiation-induced cancer. The risk increases with the exposure time, consisting of 1) time guiding the probe into and out of the heart and 2) time illuminating the contrast agent to perform the angiogram.
