Coronary angiography is a painless examination that allows you to visualize the arteries of the heart. Stent placement may be necessary depending on the results. Principle, duration, anesthesia, rest after\u2026<\/strong><\/p>\n\n\n\n

Coronary angiography is an examination that allows the cardiologist to see the coronary arteries<\/strong> when he suspects coronary artery disease, such as a narrowing of the arteries of the heart for example. This is a invasive examination <\/strong>since it is necessary to puncture thefemoral artery<\/a> or radial to allow the introduction of a catheter <\/strong>(flexible tube) into the arteries.<\/p>\n\n\n\n

In what cases should it be practiced?<\/p>\n\n\n\n

How is the exam going ?<\/p>\n\n\n\n

What are the risks or adverse effects?<\/p>\n\n\n\n

What is the definition of a coronary angiography?<\/strong><\/p>\n\n\n\n

There coronary angiography<\/strong> East an examination to visualize the arteries of the heart<\/strong> (coronary arteries). This is an imaging test using X-ray radiography technique and injection of an iodinated contrast product<\/strong>. \u201c\u00a0It's a invasive examination<\/strong>,<\/em> immediately warns the cardiologist. It requires the puncture of an artery (most often the radial artery <\/strong>at the wrist, more rarely the femoral artery <\/strong>at the level of the groin fold) and the circulation of probes to the cardiac arteries<\/em>. \u00bb<\/p>\n\n\n\n

What are the indications for a coronary angiography?<\/strong><\/p>\n\n\n\n

Coronary angiography allows precisely visualize the anatomy of the three coronary arteries supplying the heart<\/strong>, and to highlight possible narrowings (stenoses) or occlusions of the arteries<\/strong> by atheroma and\/or blood clots and assess their severity.<\/p>\n\n\n\n

\u25ba First intention: <\/strong>Coronary angiography is the examination carried out during myocardial infarction<\/strong>, in order to identify the artery responsible for the \u201cheart attack\u201d.<\/p>\n\n\n\n

\u25ba As a second intention: <\/strong>in case angina pectoris (angina)<\/strong> after performing a stress test, stress echocardiography or myocardial scintigraphy.<\/p>\n\n\n\n

\u25ba Systematically: before cardiac surgery operations <\/strong>(heart valve operation in particular) in order to possibly treat diseased arteries during the same operating procedure.<\/p>\n\n\n\n

\u25ba \u00ab\u00a0Other indications may be given by the cardiologist, depending on the particular case of each patient<\/strong><\/em>\u201c\u00a0<\/p>\n\n\n\n

How is a coronary angiography performed?<\/strong><\/p>\n\n\n\n

The exam takes place in a specially equipped x-ray room<\/strong>. Due to the introduction into the body of material, the procedure is carried out in sterile conditions<\/strong>, like in the operating room. The interventional cardiologist is dressed like a surgeon: sterile coat and gloves, mask and cap. A systematic preliminary questioning will have made it possible to detect possible (but rare) contraindications such as an allergy to the contrast product (iodine). <\/p>\n\n\n\n

\u25ba The patient, after having had a <\/strong>local anesthesia<\/strong><\/a>, is lying down, with an empty stomach <\/strong>(no drink or food 4 hours before), on an examination table, and a camera rotates around it to acquire images of the coronary arteries from many angles. <\/p>\n\n\n\n

\u25ba The interventional cardiologist will prick (puncture) the chosen artery<\/strong> as an approach (radial or femoral) and place a catheter <\/strong>which will allow very thin hollow probes to pass through. The probes are pushed through the circulation to the origin of the heart arteries. Once properly positioned, they allow injection of iodized contrast agent<\/strong>, opaque to X-rays, which makes it possible to visualize all of the coronary arteries via the camera. \u201cThe exam is painless. The injection of the contrast product may be accompanied by a feeling of heat<\/em>\u201c, specifies our interlocutor. <\/p>\n\n\n\n

\u25ba At the end of the exam, the probes and catheter are removed and the radial artery<\/strong> (or femoral) is manually compressed to avoid bleeding; then a pressure dressing is put in place and the patient can return to their room.<\/p>\n\n\n\n

How long does a coronary angiography take?<\/strong><\/p>\n\n\n\n

A simple coronary angiography generally lasts between 20 and 30 minutes.<\/strong><\/p>\n\n\n\n

Should a stent be placed after coronary angiography?<\/strong><\/p>\n\n\n\n

The results can be divided into two scenarios.<\/p>\n\n\n\n

\u25ba In the first case, there is no anomaly<\/strong> ; there is therefore no need to offer specific treatment.<\/p>\n\n\n\n

\u25ba In the second case, lesions are highlighted.<\/strong> Depending on the characteristics of the coronary artery disease, revascularization can be done in two ways:<\/p>\n\n\n\n
