Atherectomy – surgical procedure

What is Atherectomy procedure Atherectomy is a surgical procedure, done via CARDIAC CATHETERIZATION, to remove patches of arterial plaque (ATHEROSCLEROTIC PLAQUE), called atheromas, from the inner walls of major arteries such as the CORONARY ARTERIES. The cardiologist uses either a laser to vaporize or a rotary burr on the end of the catheter to shave away the atheromas. […]

Cardioversion (electrical) procedure – what is and definition

Definition of Cardioversion Procedure Cardioversion – The application of an electrical shock through the chest wall to the HEART, administered under sedation, to alter the heart’s electrical rhythm. The cardiologist performs cardioversion in a hospital setting staffed and equipped to respond to cardiovascular emergencies. There is a slight risk for HEART ATTACK or STROKE. Cardioversion is most commonly a […]

Gallop – heart sounds

What is Gallop A pair of extra HEART SOUNDS the cardiologist can hear with the bell of the STETHOSCOPE during diastole, so-named because they occur in rapid succession and sound like the hooves of a galloping horse. The characteristic sound is that of a deep-toned thud. A gallop often exists with tachycardia (rapid, regular HEART RATE) and generally signals ventricular […]

Ornish program – Dean Ornish Diet

What is Ornish program – Dean Ornish Diet An intensive lifestyle-oriented method for reducing the risk for CORONARY ARTERY DISEASE (CAD) and HEART ATTACK. Named for Dean Ornish, the American physician who developed the approach, the Ornish program features a strict vegetarian diet very low in fat along with daily YOGA, walking, MEDITATION, and participation in SUPPORT […]

Transmyocardial laser revascularization (TMLR)

What is transmyocardial laser revascularization (TMLR) A treatment for ANGINA PECTORIS and ISCHEMIC HEART DISEASE (IHD) in which the cardiovascular surgeon uses a laser to create several dozen tiny channels through the wall of the heart’s left ventricle to improve the flow of BLOOD and oxygen to the MYOCARDIUM (heart MUSCLE). The surgeon makes a small “window” incision through the ribs […]

Atherosclerosis – what is, definition, symptoms and treatment

What is Atherosclerosis and Definition Atherosclerosis is Accumulation of lipids and other materials (ATHEROSCLEROTIC PLAQUE) between the two layers of an artery’s inner wall, the intima. Over time the accumulations form brittle, hard deposits called atheromas that thicken the intima and the media (the middle of the arterial wall’s three layers). The usual consequence is that […]

Carotid Bruit sound – definition

What is Carotid Bruit sound Carotid Bruit is an abnormal sound characteristic of ATHEROSCLEROSIS that the cardiologist hears through a STETHOSCOPE placed over the carotid ARTERY at the base of the neck. The sound, a murmur that occurs during systole (contraction of the left ventricle), represents turbulence as BLOOD passes through areas of the carotid artery where atheromas (collections of ATHEROSCLEROTIC PLAQUE) occlude […]

Heart Sounds definition

What is Heart Sounds and Definiton Heart Sounds – the sounds of the opening and closing of the heart’s valves and the passage of BLOOD through them. HEART sounds are an important component of physical diagnosis for cardiovascular conditions. Doctors listen to them using a STETHOSCOPE. Heart Sounds: S1, S2, S3, S4 The classic lubb dupp sounds […]

Pacemaker definition, surgery and implanting

What is Pacemaker and Definition and function Pacemaker is a small, implanted electronic device that emits electrical impulses to maintain a regular HEART RATE. The most frequent use of a pacemaker is to treat bradycardia, an ARRHYTHMIA in which the HEART rate is persistently below 60 beats per minute. A pacemaker may also be an effective treatment for obstructive CARDIOMYOPATHY, […]

Venogram – diagnostic procedure – definition

What is Venogram – diagnostic procedure Venogram is a diagnostic procedure to evaluate the flow of blood in the veins, usually in the legs. The cardiologist may use this procedure to diagnose VARICOSE VEINS, VENOUS INSUFFICIENCY, or DEEP VEIN THROMBOSIS (DVT). For venogram, the radiologist injects a small amount of contrast dye into the affected VEIN network and […]
