Background and Objectives: Tricuspid valve (TV) repair techniques other than annuloplasty remain challenging and frequently end in tricuspid valve replacement (TVR) in complicated cases. However, the results of TVR are suboptimal compared with TV repair. This study aimed to evaluate the clinical effectiveness of TV edge-to-edge repair (E2E) compared to TVR for severe tricuspid regurgitation (TR). Methods: We retrospectively reviewed 230 patients with severe TR who underwent E2E (n=139) or TVR (n=91) from 2001 to 2020. Clinical and echocardiographic results were analyzed using inverse probability of treatment weighting analysis and propensity score matching. Results: The two groups showed no significant differences in early mortality and morbidities. During the mean follow-up of 106.2±68.8 months, late severe TR and TV reoperation rates were not significantly different between groups. E2E group, however, showed better outcomes in overall survival (p=0.023), freedom from significant tricuspid stenosis (TS) (trans-tricuspid pressure gradient ≥5 mmHg, p=0.021), and freedom from TV-related events (p<0.001). Matched analysis showed consistent results. Conclusions: E2E for severe TR presented more favorable clinical outcomes than TVR. Our study supports that E2E might be a valuable option in severe TR surgery, avoiding TVR.

The management of recurrent tricuspid regurgitation after tricuspid valve repair in patients with Ebstein anomaly is difficult, and tricuspid valve replacement is most commonly performed in such patients. We report two cases of recurrent tricuspid regurgitation in patients with Ebstein anomaly that were successfully re-repaired using the cone technique. The cone repair technique is a useful surgical method for reconstructing a competent tricuspid valve, and can be applied in patients who have undergone previous tricuspid valve repair.

Severe and permanent tricuspid regurgitation induced by pacemaker leads is rarely reported in the literature. The mechanism of pacemaker-induced tricuspid regurgitation has been identified, but its management has not been well established. Furthermore, debate still exists regarding the proper surgical approach. We present the case of a patient with severe tricuspid regurgitation induced by a pacemaker lead, accompanied by triple valve disease. The patient underwent double valve replacement and tricuspid valve repair without removal of the pre-existing pacemaker lead. The operation was successful and the surgical procedure is discussed in detail.

A 37-year-old man was transferred to our level I trauma center after a road traffic accident, presenting with right acetabular fracture, multiple rib fractures, epidural hemorrhage, and liver contusion. Severe traumatic tricuspid regurgitation was also discovered during the work-up for surgery. Our initial attempt at acetabular surgery failed when the patient experienced near cardiac arrest during anesthetic induction. It was hence decided that tricuspid valve repair should precede orthopedic surgery. Minimally invasive tricuspid valve repair using the double orifice technique was successfully performed. Subsequently, acetabular surgery was performed and he was discharged 35 days post-trauma without any complications.

A 51-year-old male was admitted three month previously with a cardiac stab injury and he underwent direct cardiac repair He had no problem after this event. He complained of dyspnea that stalled 2 months after the original injury. Echocardiography showed severe tricuspid regurgitation and so, chordac replacement and ring annuloplasty was performed. Herein we report on a case of tricuspid valve repair for treating tricuspid insufficiency following a cardiac stab injury.

Ebstein's anomaly is a complex congenital defect of the tricuspid valve and right ventricle. Various surgical methods to repair the regurgitant tricuspid valve have been reported, and most of them depend on monocuspidalization with using the anterior leaflet. We report here on our first experience with Ebstein's anomaly in a 31-year-old female patient who underwent cone reconstruction of the tricuspid valve with using three leaflets.

Residual significant tricuspid regurgitation after mitral valve operation may significantly increase postoperative morbidity and mortality. However, routine techniques to detect tricuspid regurgitation preoperatively and postoperatively are not accurate. Doppler echocardiography was performed preoperatively and postoperatively to assess its ability to evaluate and quantify the severity of tricuspid regurgitation. In 34 patients with tricuspid regurgitation secondary to mitral valvular disease the tricuspid regurgitations were semiquantified on a scale of 1 to 3+. The 34 patients were divided into two groups on the basis of severity of tricuspid regurgitation as assessed by preoperative Doppler echocardiography. Group I [8 patients] had mild[1+] regurgitation, and group II [26 patients] had moderate to severe[2 ~ 3%] tricuspid regurgitation. In all studied patients, preoperative Doppler echocardiographic studies for the degree of tricuspid regurgitation were correlated with clinical symptoms[including NYHA class] and hemodynamics[JVP and right ventricular systolic pressure], and used as the indicator to determine whether tricuspid annuloplasty should be performed or not. Patients with significant tricuspid regurgitation[group II ] had greater preoperative right ventricular systolic pressures and NYHA classes, although there was no correlation between them. The 8 patients with mild[1+] tricuspid regurgitation[group I ] didn`t undergo any procedure for the tricuspid regurgitation and their postoperative Doppler echocardiographic studies showed the less than mild[0 ~ 1+] tricuspid regurgitation, and the 26 patients with significant[>2+] tricuspid regurgitation, and the 26 patients with significant[>2+] tricuspid regurgitation[group II ] underwent tricuspid annuloplasty for the tricuspid regurgitation and the postoperative Doppler echocardiographic studies showed the findings similar to group I except 1 patient who underwent Carpentier`s ring annuloplasty and had severe right ventricular failure. Therefore, preoperative Doppler echocardiography can accurately assess the relative severity of tricuspid regurgitation. Importantly, postoperative Doppler echocardiography could conveniently determine the effect of tricuspid annuloplasty for the patients with significant tricuspid regurgitation. Doppler echocardiography may be an important diagnostic method both for evaluating the degree of residual tricuspid regurgitation after left heart operation as well as for determining which patients should undergo tricuspid valve repair.

Cardiac computed tomography (CT) and cardiac magnetic resonance imaging (CMR) can reveal the detailed anatomy and function of the tricuspid valve and right ventricle (RV). Quantification of tricuspid regurgitation (TR) and analysis of RV function have prognostic implications. With the recently available transcatheter treatment options for diseases of the tricuspid valve, evaluation of the tricuspid valve using CT and CMR has become important in terms of patient selection and procedural guidance. Moreover, CT enables post-procedural investigation of the causes of valve dysfunction, such as pannus or thrombus. This review describes the anatomy of the tricuspid valve and CT and CMR imaging protocols for right heart evaluation, including RV function and TR analyses. We also demonstrate the pre-procedural planning for transcatheter treatment of TR and imaging of postoperative complications using CT.

Tricuspid annuloplasty with the flexible Duran ring may result in a physiologic repair while maintaining the dynamic morphology of the tricuspid annulus. A method for a durable three-dimensional tricuspid annular reconstruction, which retains the plasticity and orifice area of the tricuspid annulus, is described.

A 55-year-old man underwent emergent sternotomy due to cardiac tamponade occurring just after an accidental fall from a 10-m height. Tricuspid valve regurgitation was found on echocardiography while he was on mechanical ventilation after the operation. The patient was weaned successfully from mechanical ventilation after tricuspid valve repair under cardiopulmonary bypass. Traumatic tricuspid valve regurgitation is a rare blunt chest injury and its symptoms occur late. Tricuspid regurgitation should be considered as a reason for failure to wean from mechanical ventilation after blunt cardiac trauma.
