Can the tumour of division of room diaphragm cure?

summary

There are two types of septal tumors: true (congenital) and false (acquired). True membranous tumor or membranous protrusion is a congenital malformation in which the membranous septum of the heart protrudes to the right side of the cardiac cavity. Pseudomembranous aneurysm, also known as tricuspid valve tumor and tricuspid valve prolapse, is a natural outcome of ventricular septal defect. Can the tumour of division of room diaphragm cure?

In the early stage of the disease, it was thought that the ventricular septal aneurysm was related to endocarditis, but it was not confirmed clinically. Over the past 10 years, it has been considered that the following factors may be related to: 1. Due to abnormal embryonic development, insufficient septal metastasis and insufficient rotation of aorta, the aorta is slightly dextral, the membranous septum is oblique or horizontally displaced, and the unsupported membranous septum is affected by left ventricular hypertension, resulting in aneurysm like protrusion. 2. The membranous ventricular septum has some weak areas due to abnormal natural closure process, or septal atresia is slow, but the ventricular septum is still developing, and the left ventricular hypertension leads to cystic deformation.

Common symptoms: slow growth, exertional palpitation, shortness of breath, limited activity, repeated pulmonary infection, both men and women can have the disease, but men are more than women, about 2 ∶ 1. Most of the patients are prone to upper respiratory tract infection, children have varying degrees of growth restriction, a small number of patients can be asymptomatic. There were systolic murmurs of grade Ⅱ - Ⅳ with tremor in the third and fourth intercostals of the left sternum. Some patients with P2 hyperfunction with early systolic click.

The general principle of operation is to remove the tumor, repair the defect of ventricular septum, and avoid damage to the surrounding important tissues. All operations were performed under cardiopulmonary bypass. For true membranous tumors, the edge of the tumor capsule and ventricular septal defect must be confirmed first, and the patch or direct suture should be determined according to its size. If the base is more than 1cm, the tumor should be resected and repaired with patch of corresponding size; If the base is less than or equal to 1 cm, the tumor is folded and sutured continuously, and then the base plate is used to reinforce the suture. In the case of single repair, the membranous tumor may continue to develop or re perforate. Pseudomembranous aneurysm is composed of some thickened tricuspid valve structures. If it does not cause right ventricular obstruction, it does not need to be operated too much. It only needs to close the edge of the basal ventricular defect to the root of the tricuspid septal valve and block the left to right shunt. As the edge of the fiber is all around the ventricular defect, as long as the needle is not too deep, the conduction bundle will not be injured.

matters needing attention

The prognosis is generally good. Twenty six patients were followed up for an average of 5 years and 9 months. There were no conscious symptoms and residual shunt murmur. The chest X-ray and ECG examination for more than one year had returned to normal. Echocardiography showed that membranous aneurysm disappeared without residual shunt, tricuspid regurgitation was significantly reduced, and the atrioventricular diameter was normal.
