¿'s aortic root?
The aorta is the main artery of the body, originating from the heart and distribute oxygenated blood throughout the body. The most proximal portion is called the aortic root and in those few inches are included out of the left ventricle, aortic valve and the origins of the coronary arteries.
¿By that must be treated by surgery?
The affectation with more important clinical repercussion of the aortic root is its dilatation.
The dilatation of the aortic root can cause a separation of areas fixation aortic valve, causing a lack of contact of the aortic leaflets and improper closing of the valve with the corresponding more or less severe leakage of blood into the left ventricle ie;one aortic valve insufficiency.
It is also possible that the aortic valve is located degenerate and although their size is normal is associated with a dilatation of the first portion of the aorta where the origins of the coronary arteries.
The surgical indication is marked by the degree of valvular affectation or the degree of dilatation of the aortic root.
The bad valve function has implications for the function of the left ventricle and thus the quality of life and prognosis.
The excessive dilation of the aortic root carries an associated risk of breaking any of the layers of the aorta, which is known as aortic dissection, requiring emergency surgery.
Fix the valve problem and dilatation of the aortic root involves the need to reposition the origins of the coronary arteries. This can only be achieved with open surgery.
¿That benefits for the patient is supposed intervention?
If the degree of valvular affectation is important, the correction of this problem is going to get an improvement in clinical status and better prognosis.
If the indication for surgery is due to the increased diameter of the root and valvular function is almost normal, the patient was found asymptomatic before and after surgery, but the risk of aortic rupture or dissection there will be gone.
Risks and contraindications.
The risk of elective surgery, ie one that is not performed surgery or following the added complication is not greater than the elective surgery for aortic valve. Figures very low surgical risk.
In the surgery of aortic root can be performed, in addition to the elimination of the dilatation and reimplantation of the coronary arteries, techniques of aortic valve repair retaining own valve of the patient as well as all the techniques of valve replacement using mechanical and biological prostheses ( source animal or human).
The surgery of the aortic root, by itself does not present any contraindication. However, as in much of the cardiac surgery is the patient himself who by his general condition and duration expectancy and quality of life that may discourage a surgical intervention.
