A ventricular outflow tract obstruction means there is a limitation in the blood flow out of either the right or left ventricles of the heart, depending on where the obstruction is. This can lead to cardiac hypertrophy, dilatation of the heart, and ultimately heart failure in some cases. [1] The right side of the heart is much smaller and ...
Tetralogy of Fallot ( TOF ), formerly known as Steno-Fallot tetralogy, [ 9] is a congenital heart defect characterized by four specific cardiac defects. [ 4] Classically, the four defects are: [ 4] pulmonary stenosis, which is narrowing of the exit from the right ventricle; a ventricular septal defect, which is a hole allowing blood to flow ...
Apical four chamber ultrasound view of heart. Transthoracic echocardiography (TTE) uses ultrasonic waves for continuous heart chamber and blood movement visualization. It is the most commonly used imaging tool for diagnosing heart problems, as it allows non-invasive visualization of the heart and the blood flow through the heart, using a technique known as Doppler.
D000792. OPS-301 code. 3–60. [ edit on Wikidata] Angiography or arteriography is a medical imaging technique used to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins, and the heart chambers. Modern angiography is performed by injecting a radio-opaque contrast agent into ...
Superior vena cava syndrome ( SVCS ), is a group of symptoms caused by obstruction of the superior vena cava ("SVC"), a short, wide vessel carrying circulating blood into the heart. The majority of cases are caused by malignant tumors within the mediastinum, most commonly lung cancer and non-Hodgkin's lymphoma, directly compressing or invading ...
8.9 million (2015) [ 12] Coronary artery disease ( CAD ), also called coronary heart disease ( CHD ), ischemic heart disease ( IHD ), [ 13] myocardial ischemia, [ 14] or simply heart disease, involves the reduction of blood flow to the cardiac muscle due to build-up of atherosclerotic plaque in the arteries of the heart. [ 5][ 6][ 15] It is the ...
Obstructive shock is one of the four types of shock, caused by a physical obstruction in the flow of blood. [ 1] Obstruction can occur at the level of the great vessels or the heart itself. [ 2] Causes include pulmonary embolism, cardiac tamponade, and tension pneumothorax. [ 3] These are all life-threatening.
Cardiac surgery. Heart sounds of a ventricular septal defect in a 14-year-old girl. A ventricular septal defect ( VSD) is a defect in the ventricular septum, the wall dividing the left and right ventricles of the heart. The extent of the opening may vary from pin size to complete absence of the ventricular septum, creating one common ventricle.
