2. 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.

3. Coronary artery bypass surgery - Wikipedia

   en.wikipedia.org/wiki/Coronary_artery_bypass_surgery

   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 ...

4. 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 ...

5. Diagnosis of myocardial infarction - Wikipedia

   en.wikipedia.org/wiki/Diagnosis_of_myocardial...

   In difficult cases or in situations where intervention to restore blood flow is appropriate, coronary angiography can be performed. A catheter is inserted into an artery (typically the radial or femoral artery [21]) and pushed to the vessels supplying the heart. A radio-opaque dye is administered through the catheter and a sequence of x-rays ...

6. Fractional flow reserve - Wikipedia

   en.wikipedia.org/wiki/Fractional_flow_reserve

   The decision to perform a percutaneous coronary intervention (PCI) is usually based on angiographic results alone. Angiography can be used for the visual evaluation of the inner diameter of a vessel. In ischemic heart disease, deciding which narrowing is the culprit lesion is not always clear-cut.

7. Coronary CT angiography - Wikipedia

   en.wikipedia.org/wiki/Coronary_CT_angiography

   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.

8. Interventional cardiology - Wikipedia

   en.wikipedia.org/wiki/Interventional_cardiology

   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 ...

9. Cardiac imaging - Wikipedia

   en.wikipedia.org/wiki/Cardiac_imaging

   Apical four chamber ultrasound view of heart. Transthoracic echocardiography (TTE) uses ultrasonic waves for continuous heart chamber and blood movement visualization. It is the most commonly used imaging tool for diagnosing heart problems, as it allows non-invasive visualization of the heart and the blood flow through the heart, using a technique known as Doppler.
