Echocardiography ("echo"): Ultrasonography of the heart to inspect chambers, valves, and blood flow. Often utilizes the Doppler effect to determine blood flow through valves (stenosis & regurgitation) and through the septum (ASD & VSD). Agitated saline can be used as contrast for blood flow and microbubbles for capillary blood flow contrast.
Blood is flowing into the right atrium from the superior and inferior venae cavae and the coronary sinus. Blood flows into the left atrium from the four pulmonary veins. The two atrioventricular valves, the tricuspid and mitral valves, are both open, so blood flows unimpeded from the atria and into the ventricles.
A variety of blood tests are available for analyzing cholesterol transport behavior, HDL, LDL, triglycerides, lipoprotein little a, homocysteine, C-reactive protein, blood sugar control: fasting, after eating or averages using glycated albumen or hemoglobin, myoglobin, creatine kinase, troponin, brain-type natriuretic peptide, etc. to assess the evolution of coronary artery disease and ...
This can be used to show blood flow through the valves to visually indicate the direction of blood flow. Abnormal blood flow can reflect stenosis and regurgitation of the valve. Color doppler can also show blood flow in abnormal locations such as with septal defects (ASD or VSD). Color doppler can also be applied to M-mode.
A heart valve is a biological one-way valve that allows blood to flow in one direction through the chambers of the heart. A mammalian heart usually has four valves. Together, the valves determine the direction of blood flow through the heart. Heart valves are opened or closed by a difference in blood pressure on each side. [1] [2] [3]
Heart valves can malfunction for a variety of reasons, which can impede the flow of blood through the valve and/or let blood flow backwards through the valve (regurgitation). Both processes put strain on the heart and may lead to serious problems, including heart failure. While some dysfunctional valves can be treated with drugs or repaired ...
Multiple tests for specific blood components, such as a glucose test or a cholesterol test, are often grouped together into one test panel called a blood panel or blood work. Blood tests are often used in health care to determine physiological and biochemical states, such as disease , mineral content, pharmaceutical drug effectiveness, and ...
Bicuspid aortic valve; Other names: Bicommissural aortic valve [1] The aortic valve controls outflow of blood from the left ventricle of the heart through the aorta (valve is indicated within the yellow highlighted box). A normal aortic valve is tricuspid. Five types of bicuspid valve are shown, with Type 1 being most prevalent.
