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.
An alternative to open heart surgery, percutaneous valve repair is performed on the mitral valve using the MONARC system or MitraClip system [7] Coronary thrombectomy Coronary thrombectomy involves the removal of a thrombus (blood clot) from the coronary arteries. [8] Open heart surgery of the heart is performed by a cardiothoracic surgeon ...
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 ...
A percutaneous coronary intervention, 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 percutaneous approach that is widely used today was developed by radiologist Sven-Ivar Seldinger in 1953. [9] [10] Percutaneous access of the artery or vein is still commonly known as the Seldinger technique. The use of the Seldinger technique for visualizing the coronary arteries was described by Ricketts and Abrams in 1962 and Judkins in ...
Angiography or arteriography is a medical imaging technique used to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins, and the heart chambers. Modern angiography is performed by injecting a radio-opaque contrast agent into the blood vessel and imaging using X-ray based ...
A coronary catheterization is a minimally invasive procedure to access the coronary circulation and blood filled chambers of the heart using a catheter. It is performed for both diagnostic and interventional (treatment) purposes. Coronary catheterization is one of the several cardiology diagnostic tests and procedures.
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.
