Coronary catheterization can treat a disease that has recently affected all Arabs and is an epidemic in the heart due to bad habits, so Dr. Sameh Allam explains all the details of the procedure in the video. Introduction 00:00 Coronary catheterization (diagnostic catheterization) 00:58 Therapeutic coronary catheterization 01:50 How is cardiac catheterization performed (balloon and stents) 02:55 Recovery period from coronary catheterization 05:35 ____ Coronary catheterization is performed like any type of cardiac catheterization for two main reasons, which are either a diagnostic catheterization to examine blood flow in the coronary arteries, in addition to examining blood flow and blood pressure in the heart chambers, i.e. the atria and ventricles, and determining the performance of the valves and whether they have a defect or disease and problems with the contraction of the various walls of the heart. Coronary catheterization is called percutaneous surgical intervention. Another purpose of coronary catheterization is therapeutic catheterization, which aims to treat narrowed arteries by expanding them with a balloon only or inserting a heart stent after the balloon to maintain their expansion. The stent can be changed from time to time or more heart stents can be installed. But first, before going into more details, we must know the following: What is a coronary artery? The right coronary artery and the left coronary artery are the most important arteries in the body and among the most important blood vessels in the human body. They are the most famous arteries and the most vulnerable to injury in the Arab world due to the accumulation of fat and bad eating habits. The importance of the coronary arteries is due to the fact that they branch off from the aorta, which comes out of the heart directly, and supplies the heart muscle with its most important food, which is oxygen, which in turn supplies the rest of the body with all the oxygen-laden blood it needs. The right coronary artery comes on the branches of the marginal artery and the anterior interventricular artery. What is the function of the coronary artery? The coronary arteries carry oxygenated blood to the heart muscle for the purpose of nourishing it, but because the coronary arteries are divided into two main arteries, each one has a function as follows: 1. The function of the left coronary artery is to transport blood to the left side of the heart muscle, and it comes in many branches, which are the left anterior descending artery and the reflex artery. 2. The function of the right coronary artery The function of the coronary artery is to supply blood to the right ventricle, right atrium, and sinoatrial node. The right coronary artery is divided into smaller branches, which include the posterior descending artery, the acute marginal artery, and the left anterior descending artery. The function of the coronary artery is summarized as follows: transporting blood through the heart chambers and nodes. Coronary artery disease Coronary artery disease is a common heart disease, in which there is a blockage in the coronary arteries that mainly supply the heart, causing a disturbance in blood flow through the blood vessels in the whole body, especially the heart, and the main cause is the accumulation of cholesterol and fatty plaques, which causes blockage or enlargement of the artery itself, i.e. an increase in its thickness due to inflammation of the heart muscle. Symptoms of coronary artery disease Heart attack Angina Shortness of breath General weakness Is coronary artery catheterization dangerous? Coronary artery catheterization is one of the safest procedures used in the medical field. This type of catheterization rarely causes serious or minor complications. Coronary artery catheterization is used to treat or diagnose problems with the coronary arteries or the valves connected to them. Light local anesthesia is given at the site of catheterization, such as the thigh, neck, and hands. General anesthesia is rarely used except in critical cases or advanced age that cannot tolerate the procedure. It is necessary to follow the warnings of the treating cardiologist before and after the procedure, such as fasting and stopping certain medications before the procedure for a period determined by the doctor depending on the case. After the procedure, a course of medications designated for coronary artery catheterization or stenting must be followed. What does the patient feel after the catheterization procedure? The patient usually feels slight numbness at the site of the wound in the hand and thigh after waking up from the catheterization procedure. However, the patient should contact the treating physician immediately if these symptoms persist for three days after the coronary artery catheterization. How long does a heart catheterization procedure take? The time it takes for a coronary artery catheterization depends on its type. A diagnostic cardiac catheter
