What is Heart Surgery? (I)
Author: rusman
The heart can be defined as a muscular pump about the size of a fist that pumps blood continuously to distribute throughout the body. It is composed of four compartments or chambers, two atria or receiving chambers and two ventricles or chambers of expulsion. Each ventricle has an inlet valve or inlet and outlet valve.
The right atrium connects to the right ventricle through the tricuspid valve and right ventricular outflow is the pulmonary valve. Venous blood throughout the body, with little oxygen reaches the right atrium and is pumped by the right ventricle to the lungs so it can oxygenate arterial blood and become red and very oxygen.
The left atrium connects with the left ventricle through the mitral valve and left ventricular outflow is the aortic valve. Oxygenated blood into the lungs reaches the left atrium and is pumped at high pressure into the left ventricle to the aorta artery with all its branches to irrigate and oxygenate the entire body.
Problems with heart valves are usually, in most cases, caused by congenital defects, changes caused by rheumatic fever, infection, or degeneration and wear their own tissues with age.
The involvement of the valves may cause it do not open properly with hindering blood flow, stenosis, or not close completely causing a loss, regurgitation, or a combination of both, double valve lesions.
The valve malfunctions can affect more than one valve and is very common for two valves are affected and even three valves may be damaged. Is an exception that is required to act on the four heart valves.
When a valve failure, the heart is forced to make a much greater. As a general rule we can say that the failure of the valves occurs in a progressive and evolving over the years with what the heart is adapting and accommodating to excessive work to do. That’s why after years of supporting the added work is when the heart can begin to show signs of failure and symptoms begin to appear. On the other hand, when the failure or valvular rupture is sudden, the heart does not have time to settle and the symptoms develop much more severe.
Medications can not get the valves to open properly or leaks are gone, this means that when clinical conditions require any need for surgery to treat valvular affectations.
