Traumatic Tricuspid Valve Injury: Leaflet Resuspension Repair Joe W. R. Bolton, MD Department of Cardiothoracic Surgery, Wilford Hall USAF Medical Center, Lackland Air Force Base, Texas Blunt traumatic rupture of the tricuspid valve is exceedingly u n c o m m o n , and injury of the tricuspid valve due to penetrating trauma appears to be even more rare. Presented here is a case of tricuspid valve injury due to penetrating cardiac trauma repaired by leaflet resuspension 17 years later.
(Ann Thorac Surg 1996;61:721-2) he patient is a 37-year-old man who was a d m i t t e d for evaluation of severe shortness of b r e a t h and dysp n e a on exertion. His past history was significant for a stab w o u n d to the right ventricle at 20 years of age, which was r e p a i r e d via an u n c o m p l i c a t e d left thoracotomy and oversewing of the stab wound. There was no evaluation of intracardiac structures. Over the next 17 years he r e q u i r e d n u m e r o u s hospital admissions for progressive shortness of b r e a t h a n d was unable to p e r f o r m even the lightest workload. On admission, the patient was m o d e r a t e l y short of breath and mildly dyspneic. Physical examination was significant for a m u r m u r of tricuspid insufficiency.

valve repair or replacement. During cannulation, the tricuspid regurgitant jet was p a l p a t e d through the right atrial a p p e n d a g e and felt to be totally unrestricted. After institution of c a r d i o p u l m o n a r y bypass with bicaval cannulation and aortic cross-clamping the right atrium was opened. Inspection of the tricuspid valve revealed the septal a n d posterior leaflets to be intact. The anterior leaflet was almost completely d e t a c h e d from the annulus, being connected only at the commissure of the septal leaflet. The subvalvular m e c h a n i s m was intact. The annulus was t r e m e n d o u s l y dilated. The valve was r e p a i r e d by leaflet r e s u s p e n s i o n along the annulus with a continuous 4-0 Prolene suture (Ethicon, Somerville, NJ). Because the greatly dilated annulus p r e c l u d e d a d e q u a t e leaflet approximation, the valve was bicuspidized by closing the cleft b e t w e e n the anterior and posterior leaflets with i n t e r r u p t e d figure-of-8 5-0 Prolene suture and a 36-mm C a r p e n t i e r - E d w a r d s tricuspid valve annuloplasty ring was placed. Testing with saline solution revealed a mild central jet without prolapse. The patient was easily w e a n e d from c a r d i o p u l m o n a r y bypass. After decannulation, p a l p a t i o n through the atrial a p p e n d a g e revealed a small tricuspid jet, which was greatly r e d u c e d from the torrential flow noted on preoperative palpation. A right atrial pressure m e a s u r i n g line was placed through the tricuspid valve into the right ventricle a n d on pull-back revealed the expected right atrial pressures, which m i m -

Six weeks after the operation he r e t u r n e d to work for the first time since his original injury. At 3-month follow-up, he r e m a i n e d in sinus r h y t h m and had a decrease in the size of his cardiac s h a d o w by chest r o e n t g e n o g r a m (Fig 4). Comment Isolated traumatic injury to the tricuspid valve a n d its s u p p o r t i n g structures is extremely rare, with only about 100 cases having b e e n r e p o r t e d in the literature [1-3]. Even though 94% of cardiac t r a u m a involves p e n e t r a t i n g injuries, the vast majority of r e p o r t e d cases of traumatic tricuspid insufficiency has been due to b l u n t t r a u m a [3]. Of those injuries involving cardiac valves, aortic valve r u p t u r e is most frequent, followed by d a m a g e to the mitral valve. Injury to the tricuspid valve is the most rare of valvular injuries [4]. The original t r e a t m e n t of traumatic tricuspid insufficiency was valve repair because the results of valve r e p l a c e m e n t in this position were poor. Valve replace-

m e n t with a porcine bioprosthesis did not offer an acceptable longevity and the use of a mechanical valve resulted in an unacceptable incidence of t h r o m b o e m b o lism a n d complications associated with long-term anticoagulation. Unfortunately, an initial poor experience resulting from residual a n d recurrent valvular insufficiency resulted in long-term nonoperative m a n a g e m e n t because the tricuspid regurgitation could be well tolerated for years [2, 4, 5]. However, because of worsening s y m p t o m s nearly all patients eventually came to operation. Valve r e p l a c e m e n t then b e c a m e the operation of choice due to the prior poor experience with repair. Techniques d e v e l o p e d with mitral valve repair have i m p r o v e d the ability to attain acceptable results from tricuspid valve repair after blunt or penetrating trauma. Currently, it is r e c o m m e n d e d that an attempt should be m a d e to repair the valve even if valve r e p l a c e m e n t at a later date m a y be inevitable [2-7]. It is i m p o r t a n t to be aware of a wide variety of techniques because the nature of the injury dictates the m e t h o d of repair. Most injuries involve the subvalvular structures, and because of the usual delay in diagnosis s p a n n i n g weeks to years, a dilated annulus is nearly always present. In these cases, it is necessary to address not only the injury to the papillary muscles or chordae, b u t also the a n n u l a r dilatation. Occasionally, as in this case, the valve leaflet itself dem a n d s attention. W i t h the techniques available today, once diagnosed, the tricuspid insufficiency should be a p p r o a c h e d surgically with a plan t o w a r d repair. The specific repair is g u i d e d by the circumstances and requires ingenuity a n d innovation. Although valve r e p l a c e m e n t is sometimes necessary,, the r e p o r t e d results after operation, either acute or delayed, have b e e n gratifying. The majority of patients who have u n d e r g o n e reparative operations, as in this case, have been freed from their disability and r e t u r n e d to a productive lifestyle.
