Tricuspid valve surgery; It is caused by the repair or replacement of the heart valve between the right atrium and the right ventricle. Repair is generally preferred over replacement. The reason is that it is prone to thrombosis formation. Surgery is feared and avoided because it is more common in patients who have had mitral valve surgery, and because the heart conduction system may be affected during the operation. Nowadays, minimally invasive techniques and performing them on a functioning heart reduce the risk to some extent. Repair or replacement of the functioning heart is performed by subaxillary thoracotomy.

The patient is placed on the left side of the chest under double lumen intubation and general anesthesia; That is, an anterolateral thoracotomy position is given with the chest on the right side. A vertical 6 cm incision is made on the intersection of the subaxillary line and the right breast line, pectoralis major and pectoralis minor. without cutting the muscles It is dissected and a retractor is placed. 3. The thorax is entered through the intercostal space and right lung ventilation is turned off or, if not tolerated, the tidal volume is reduced. The pericardium opens and its leaves hang on the chest wall. Aorta, right and left atrium are clearly seen. The aorta, right auricle, and right atrium are easily cannulated. The patient is connected to a heart-lung pump, providing extra-corporeal support for arterial blood pressure, and the vena cava is closed with a tourniquet while the heart is working.

A right atriotomy is performed and the atriotomy is closed after tricuspid repair or replacement while the heart is working. The heart is easily decannulated. After bleeding control, a single chest drain is placed in the thorax (the location of the drain is important to avoid pain), the ribs are brought closer, and the muscles, subcutaneous and skin are closed properly. Postoperative follow-up is important. Since diuresis and bleeding complications are generally common in these patients, close follow-up is required.
