  2. Coronary artery bypass surgery - Wikipedia

    en.wikipedia.org/wiki/Coronary_artery_bypass_surgery

    Coronary artery bypass surgery aims to prevent death from coronary artery disease and improve quality of life by relieving angina, the associated feeling of chest pain. [1] The decision to perform surgery is informed by studies of CABG's efficacy in different patient subgroups, based on the lesions' anatomy or how well the heart is functioning.

  3. Coronary artery anomaly - Wikipedia

    en.wikipedia.org/wiki/Coronary_artery_anomaly

    Coronary arteries are vessels supplying blood and nutrients to the heart muscle (). [1]Coronary arteries arise from ostia, openings of the aorta (the largest artery in the human body) at the upper third or middle third of the sinuses of Valsalva (the first part of the big pipe coming off the main pumping chamber).

  4. ICD-10-CM - Wikipedia

    en.wikipedia.org/wiki/ICD-10-CM

    The ICD-10 Clinical Modification (ICD-10-CM) is a set of diagnosis codes used in the United States of America. [1] It was developed by a component of the U.S. Department of Health and Human services, [ 2 ] as an adaption of the ICD-10 with authorization from the World Health Organization .

  5. Instantaneous wave-free ratio - Wikipedia

    en.wikipedia.org/wiki/Instantaneous_wave-free_ratio

    The instantaneous wave-free ratio (iFR, sometimes referred to as the instant wave-free ratio or instant flow reserve) is a diagnostic tool used to assess whether a stenosis is causing a limitation of blood flow in coronary arteries with subsequent ischemia. iFR is performed during cardiac catheterisation (angiography) using invasive coronary pressure wires which are placed in the coronary ...

  6. Coronary artery ectasia - Wikipedia

    en.wikipedia.org/wiki/Coronary_artery_ectasia

    Coronary artery ectasia is characterized by the enlargement of a coronary artery to 1.5 times or more than its normal diameter. [1] The disease is commonly asymptomatic and is normally discovered when performing tests for other conditions such as coronary artery disease, stable angina and other acute coronary syndromes.

  7. ICD-10 Procedure Coding System - Wikipedia

    en.wikipedia.org/wiki/ICD-10_Procedure_Coding_System

    The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.

  8. Spontaneous coronary artery dissection - Wikipedia

    en.wikipedia.org/wiki/Spontaneous_coronary...

    The tracking of blood within the artery wall (both in the presence or absence of an intimal tear) is referred to as a "false lumen". [10] [11] [12] The restriction of blood flow in the 'true' lumen limits the availability of oxygen and nutrients to the heart muscle, or myocardium. As a result, the myocardium continues to demand oxygen but is ...

  9. Percutaneous coronary intervention - Wikipedia

    en.wikipedia.org/wiki/Percutaneous_coronary...

    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. PCI is considered 'non-surgical ...
