How is tumour of division of room diaphragm treated?

summary

There are two types of ventricular septal tumors: true (congenital) and false (acquired), so the treatment has become a hot topic. 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, tricuspid valve prolapse, is a phenomenon of natural outcome of ventricular septal defect. So let's share how to treat the tumors of the lower interventricular septum?.

How is tumour of division of room diaphragm treated?

First: indications for surgery (1) simple small ventricular septal tumors, asymptomatic and hemodynamic changes, can be followed up, tumor size should be considered for surgical treatment.

Second, the indications of surgery for membranous tumors with tumor perforation are the same as those for membranous ventricular septal defect.

Third, the general principle of surgical method is to remove the tumor, repair the defect of ventricular septum, and avoid damaging 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.
