Correction of traumatic tricuspid insufficiency using the double orifice technique.

Traumatic tricuspid insufficiency is an uncommon clinical condition and surgical procedures vary. In this paper we report our experience in treating traumatic tricuspid insufficiency using the double orifice technique. From January 2000 to September 2003, 10 patients with traumatic tricuspid regurgitation were admitted to our hospital, 5 of whom were corrected using the double orifice technique. There were 4 males and 1 female with ages ranging from 31 to 52 years. Preoperative transthoracic echocardiography (TTE) detected severe tricuspid regurgitation in 4 patients and moderate tricuspid regurgitation in 1 patient. At surgery, tear of the tricuspid anterior papillary muscle was found in 2 cases and anterior chordal rupture in 3 cases. The valves were successfully repaired using the double orifice technique in combination with ring annuloplasty. There was no repeat operation, no operative complications or deaths. Before discharge, TTE detected normal tricuspid valve function in 2 cases and tiny regurgitation in 3 cases. After a follow up of 8 to 36 months, TTE demonstrated normal valve function in 1 patient and tiny regurgitation in 4 patients. The double orifice technique appears to be a simple but effective method of repairing traumatic tricuspid incompetence. Satisfactory clinical outcomes can be produced in carefully selected patients.
