Valvular Surgery (I)
Author: rusman
In the case of surgery on the valves, to lie within the heart, the only way to have a direct view of the valve is open heart surgery that requires mandatory pump or heart-lung machine. In rare cases, concrete is still used the original technique of closed mitral commissurotomy involves opening the mitral valve without opening the heart.
In the same way that the median sternotomy can reach any point of the heart, you can use other cuts of very specific approach to operations only when it is necessary to have access to a limited area. This has allowed the development of cardiac surgical techniques require incisions that can be considered minimal. The ministernotomy for surgery on the aortic valve and technique for surgery Heart Port on the mitral valve, the tricuspid valve and atrial defects.
The mitral valve is most affected by rheumatic fever. The injury will require surgical intervention can be both a poor opening of the valve, mitral stenosis, for a bad end to escape, mitral regurgitation, or a combination of both, double mitral lesion.
Although the valve functioning as such, it is possible that the muscles that support it are affected when there is a lack of blood to the heart, in which case you may see a leak, ischemic mitral regurgitation.
Whenever possible, try to repair the mitral valve. The options are manifold. Open the valve orifice when it is restricted, mitral commissurotomy, enhance support hole through rings, mitral annuloplasty, inserts, patch, resection of excess material and multiple combinations of techniques mitral valvuloplasty.
The result of the repairs is monitored by intraoperative transesophageal echocardiography, ie in the same operating room is assessed by ultrasound introduced into the esophagus if the repair was successful.
