Catheterization and interventional procedures are performed in the catheterization laboratory, a suite with X-ray equipment that allows imaging of the coroanry arteries. Generally catheterization labs are located in hospitals, although there are some outpatient, free-standing cath labs.
Cardiology is the study of the heart and related disease processes. As such, it includes coronary artery disease (blockages in heart blood vessels), valvular heart disease (leaky valves or blocked valves), heart failure and electrical system disorders. i.e. arrhythmias.
An interventional cardiologist is a cardiologist who has undertaken specialized training to perform interventional procedures on the heart. Usually this consists of placing stents in the arteries of the heart (coronary arteries) to open up blockages. This helps restore blood flow to patients who...
Interventional procedures do NOT cure coronary artery disease. Interventional procedures can help restore flow to completely blocked arteries or improve flow to severely blocked arteries. However, coronary artery disease is a systemic process and there is often plaque diffusely through the arterial.
In general, yes. Most cardiologists perform catheterization and interventional procedures with conscious sedation. This generally consists of a pain medicine (opiate) intravenously such as fentanyl and a relaxing medicine (benzodiazepine) such as versed. These medicines take the edge off of things..
