The coronary angiography is performed under local anaesthesia. The patient is awake during the procedure. An incision is made in the groin, wrist, or arm, and a catheter is inserted into the artery through it. An X-ray is used to guide the catheter to the area of blockage. A dye is inserted through the catheter to make the places of blockage ...
Coronary angiograms can be done either transradial (through the wrist) or transfemoral (through the groin). [10] The transradial route results in somewhat greater patient and operator exposure. Overall, patient exposure can range from 2 millisieverts (equivalent of about 20 chest x-ray plates) to 20 millisieverts. [ 11 ]
To diagnose a coronary occlusion, a doctor may view a patient's medical history, or perform a coronary angiography; a doctor will stick a catheter into the wrist or groin, lead it to the heart, and inject a liquid for X-ray imaging. [4] To treat a coronary occlusion, medication may be used to relieve symptoms.
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 ...
The tip of the catheter is inserted into the orifice of the bronchial artery (normally smaller than 1 mm) or other non-bronchial hemoptysis-related arteries. Contrast agent is injected through the catheter, and when abnormal findings are observed, such as systemic–pulmonary shunts, proliferations of the capillary vessels, or extravasation of ...
The history of invasive and interventional cardiology is complex, with multiple groups working independently on similar technologies. Invasive and interventional cardiology is currently closely associated with cardiologists (physicians who treat the diseases of the heart), though the development and most of its early research and procedures were performed by diagnostic and interventional ...

CABG is also performed when a patient is to undergo another cardiac surgical procedure, most commonly for valve disease, and angiography reveals a significant lesion of the coronary arteries. [9] CABG can also address dissection of coronary arteries, where a rupture of the coronary layers creates a pseudo- lumen (cavity) and diminishes blood ...
