What is Tricuspid Atresia?
The
tricuspid valve is located between the right ventricle and the atrium and opens to allow blood from the atrium to the right ventricle. In tricuspid atresia, this valve does not create properly and generally completely blocks blood flow from the hall to the chamber. Tricuspidal atresia cause immediate problems in the newborn and require emergency medical care. This may mean that the right chamber is also malformed as in the Hypoplastic Right Chamber. Often the chamber defect of the septa and the atrial defect may be present, allowing a little blood to go into the lung valve, but it does not provide sufficient amounts for proper body oxynament. It is not a repaired defect, but can be alleviated by surgery. Alternatively, parents can opt for transplantation. In general, however, parents decide to relieve surgery because they have a better level of survival in the onset and can significantly delay the need for transplantation. Sometimes it is possible to repair or replace a tricuspid valve, but generally is not possibleNot in tricuspid atresia due to its complete closure and its effects on the right chamber.
Shortly after a child with a tricuspide atresy is born, a cardiotorack surgeon placed a small shortcut in the heart to allow mixed blood to flow into the pulmonary flap. Blalock-Tussig Shunt will give the child time to grow before returning to the hospital in about three months for Glenn Shunt. Fontan is usually completed three to five years after Glenn Shunt. At that time, the right side of the heart will not have to work because the blood returning to the lungs completely bypasses the heart. The heart will only draw blood into the body, and while the right chamber can be abnormal, the left ventricle is generally size and works well.
children with rectangular flow defects, such as tricuspid atresia and hypoplastic genuine heart, tend to have a slightly better survival than children born with left -wing defects. Left Chamber in Normal SRDCI is larger and more bound to muscles than the right chamber. It is ideal for a situation that creates a fontan. On the contrary, those children who have small left ventricles must rely on the weaker right chamber to draw blood into the body. Although in both cases the heart eventually begins to fail and require transplantation, the left ventricles tend to survive as the only petrol chamber for a little longer.
In tricuspidal atresia or right ventricular hypoplasia, it is estimated that long-term survival of fontan is between 15-30 years than the necessary transplantation. Newer studies have had longer time frames. Although children undergo three operations when they are still young, they are considered more viable and less risky than transplants. The availability of donor hearts, especially for infants, is also minimal.
Fontan results in a special arrangement of "plumbing" of the heart, but usually does not limit the child of tricuspid atres by normal activities. Cardiologists can make certain prohibitions concerning to speakThe participation in competing sports is involved. Children must also be adhered to annually to ensure that the fontan is adequate.
Children with tricuspid atresia and mostly other heartflow defects must take low -dose aspirin daily and require antibiotics before dental procedures. In general, however, a child with surgically alleviated tricuspid atresia can look forward to many years of health. The continuing improvement in transplant technology can result in a much higher life expectancy than current transplantation.
