Minimally invasive tricuspid operation using port access

Background. Port-access techniques performed through a right mini-thoracotomy have been extensively described for both the mitral and aortic valves. However, reports of tricuspid valve operations using the port-access approach are rare. A technique for minimally invasive tricuspid valve operation using port access is described. Methods. Port-access approach was applied to 33 consecutive patients undergoing tricuspid valve repair or replacement. Results. Twelve percent (4 of 33) underwent tricuspid replacement and 88% underwent repair (28 of 33). Perioperative mortality was 6% (2 of 33) and conversion to median sternotomy was 3% (1 of 33). Conclusions. Port-access tricuspid operations are both feasible and safe with a low conversion rate to conventional median sternotomy.
