Treatment of Trilogy of Fallot

Trilogy of Fallot includes pulmonary stenosis, atrial septal defect (or patent foramen ovale), and right ventricular hypertrophy with a right-to-left shunt. The incidence rate accounts for 2% to 3% of congenital heart disease. This is a disease related to the heart, a congenital disease caused by partial functional defects. The heart beats every moment. If there is a problem, it must be solved as soon as possible, otherwise the risk factor is too high. Let's take a look at the treatment of trilogy of Fallot.

1. Clinical manifestations

1. Palpitations, shortness of breath, fatigue, poor development. In mild cases, cyanosis may not be obvious, while in severe cases, there may be cyanosis, squatting, or syncope.

2. Those with obvious cyanosis have clubbing of the fingers and toes, weakening or disappearance of the second sound in the pulmonary valve area, a coarse systolic blowing murmur heard in the second intercostal space on the left side of the sternum, and systolic tremor.

Second surgical treatment

1. Properly relieve outflow obstruction. The septal and parietal bundles and part of the supraventricular ridge are removed, the pulmonary valve and valve ring are incised, and the valve ring is enlarged to allow a bougie of more than 1.6 cm in adults and 1.3 to 1.4 cm in children to pass through. For patients with a small third ventricle and narrow high infundibulum, a patch is needed to widen the outflow tract. If there is also stenosis of the pulmonary valve ring, trunk or branches, a patch across the valve ring can be used to widen the tract. For ventricular septal defects under the pulmonary valve, a cross-valve ring patch should also be performed. In infants and young children, if the inner diameter of the pulmonary artery trunk is <0.7cm, the right ventricular outflow tract should be repaired and widened.

2. Perfectly repair the ventricular septal defect and prevent conduction block. The patch can be slightly smaller than the defect, but adults with tetralogy of Fallot require a patch of equal size. The patch is sutured to the right ventricular surface of the antral ventricular septum. The suture needle cannot penetrate the entire layer, the depth is about 1mm. The suturing should be tight and accurate to avoid suturing the aortic valve and atrioventricular conduction bundle. A gasket is added at the root of the tricuspid valve to prevent residual ventricular septal defect.

Postoperative Prevention

1 The focus of the prevention and treatment of Trilogy of Fallot is prevention, especially the four major preventive measures of quitting smoking, losing weight, exercising and avoiding certain foods. By changing your lifestyle, having regular checkups and taking medication, 80% of myocardial infarctions can be completely prevented or the symptoms can be greatly alleviated. Clinical experience has shown that the first measure to prevent trilogy of Fallot is to quit smoking completely; the second is to control weight, especially to reduce abdominal fat; the third is to strengthen exercise, such as brisk walking for at least 30 minutes a day, insisting on climbing stairs instead of taking the elevator, and minimizing driving and riding; fourth, pay attention to improving diet, not eating too much, and not eating too much high-fat food.

After reading the above introduction to Trilogy of Fallot, patients should be diagnosed and treated early, and postoperative prevention should also be done well. You must pay attention to quitting smoking, losing weight, eating a healthy diet, and strengthening physical exercise. Life lies in exercise. Don't eat inappropriate foods, eat more fruits and vegetables, and maintain regular living habits.
