Background: Tricuspid valve (TV) repair is the recommended treatment for severe functional tricuspid regurgitation (fTR) in patients undergoing left-sided surgery. For this purpose, a wide range of annuloplasty devices differing in form and flexibility are available. This study reports the results using a three-dimensional annuloplasty ring (Medtronic, Contour 3D Ring) for TV repair and analysis of risk factors. Methods: A cohort of 468 patients who underwent TV repair (TVr) with a concomitant cardiac procedure from December 2010 to January 2017 was retrospectively analyzed. Results: At follow-up, 96.1% of patients had no/trivial or mild TR. The 30-day mortality was 4.7%; it significantly differed between electively performed operations (2.7%) and urgent/emergent operations (11.7%). Risk factors for recurrent moderate and severe TR were LVEF < 50%, TAPSE < 16 mm, and moderate mitral valve (MV) regurgitation at follow-up. Preoperatively reduced renal function lead to a higher 30-day and overall mortality. Reoperation of the TV was required in six patients (1.6%). Risk factors for TV related reoperations were preoperative TV annulus over 50 mm and an implanted permanent pacemaker. Conclusions: TVr with the Contour 3D annuloplasty ring shows low TR recurrence and reoperation rates. Risk-factor analysis for the recurrence of TR revealed the importance of left- and right-ventricular function.

Background Functional tricuspid regurgitation (FTR) secondary to left-sided heart disease may lead to poor quality of life and reduced long-term survival. This study evaluated clinical and functional outcomes of patients undergoing tricuspid valve (TV) repair using a rigid three-dimensional ring (Contour 3D, Medtronic) concomitant with another procedure. Methods From September 2011 to July 2015, 112 patients (mean age 70.9 ± 9.0 years) were enrolled at 10 centers in Europe, Israel, and the United States. Inclusion criteria were FTR ≥ moderate and/or tricuspid annular diameter (TAD) ≥ 40 mm. Echocardiography was planned before surgery and at discharge with echocardiographic and clinical follow-ups performed 6 months postoperatively. Results Three fourths (74.4%) of patients had higher than moderate TR. Mean TAD was 41.0 ± 7.3 mm; 61.7% of patients were in the New York Heart Association (NYHA) class III/IV. The most common concomitant procedure was mitral valve repair (57 patients, 53.3%). The 30-day mortality rate was 0.9% (n = 1). The mean EuroSCORE II was 8.9 ± 8.4% (median: 5.9%; interquartile range: 3.5–11.5%). The observed to expected ratio (O/E) based on the median was 0.1. Six deaths occurred during follow-up (three cardiac related). Mean implanted ring size was 30.3 ± 2.7. At 6 months, 94.4% of patients showed ≤ mild TR, and 92.0% were in NYHA class I/II (p < 0.001 vs baseline for both). Mean pressure gradient across the TV was 2.0 ± 1.1 mm Hg; leaflet coaptation length was 7.5 ± 3.3 mm. Conclusion The Contour 3D annuloplasty ring used for treatment of FTR substantially reduced TR for up to 6 postoperative months with low mean pressure gradients across the TV and significant improvement in NYHA class.

The Impact

Background: Tricuspid ring annuloplasty (TAP) is usually performed for patients with mild or greater functional tricuspid regurgitation (TR) at the time of left-sided valve surgery. However, there were limited data regarding the shape of tricuspid annulus after TAP. The aim of this study was using three-dimensional (3D) transesophageal echocardiography to investigate the impact of the ring annuloplasty on the tricuspid annulus after TAP. Methods: 3D tricuspid valve was retrospectively analyzed in 20 patients who underwent concomitant left-sided heart surgery and TAP for functional TR. 3D data of tricuspid valve were acquired before TAP, immediate after surgery (intraoperative), and before discharge (15±5 days after TAP). TAP was performed by one surgeon using a Carpentier-Edwards Physio Tricuspid annuloplasty ring. The ring size was determined by measuring the distance from anteroseptal to posteroseptal commissures. 3D tricuspid annular area was measured. The area protruded outside the annuloplasty ring was obtained by subtracting the ring area from the annular area (Figure). Results: All 20 patients underwent successfully TAP with less than mild residual TR. Annuloplasty rings size 28mm, 30mm, 32mm, and 34mm were used in 6 (30%), 4 (20%), 5 (25%), and 5 (25%) patients, respectively. Median annular area decreased from 1074 (interquartile rage 893-1276) mm 2 before TAP to 591 (519-706) mm 2 immediate after TAP, but showed significant increase to 645 (501-766) mm 2 at the time of discharge (P<0.001). Percent area protruded outside the annuloplasty ring was 14% immediate after TAP and increased to 24% before discharge (P<0.001). Before discharge, there were 9 patients with more than mild residual TR (2 had moderate TR). Percent area protruded outside the annuloplasty ring was associated with mild or more residual TR at the discharge. Conclusion: Tricuspid annular shape after TAP was not always round. Deformation of tricuspid annulus may be associated with residual TR.

The Right

The tricuspid valve is currently the subject of much interest from echocardiographers and surgeons. Functional tricuspid regurgitation is the most frequent aetiology of tricuspid valve pathology, is characterized by structurally normal leaflets, and is due to annular dilation and/or leaflet tethering. A primary cause of tricuspid regurgitation with/without stenosis can be identified only in a minority of cases. Echocardiography is the imaging modality of choice for assessing tricuspid valve diseases. It enables the cause to be identified, assesses the severity of valve dysfunction, monitors the right heart remodelling and haemodynamics, and helps decide the timing for surgery. The severity assessment requires the integration of multiple qualitative and quantitative parameters. The recent insights from three-dimensional echocardiography have greatly increased our understanding about the tricuspid valve and its peculiarities with respect to the mitral valve, showing promise to solve many of the current problems of conventional two-dimensional imaging. This chapter provides an overview of the current state-of-the-art assessment of tricuspid valve pathology by echocardiography, including the specific indications, strengths, and limitations of each method for diagnosis and therapeutic planning.

Abstract Aims Atrial functional tricuspid regurgitation (A-FTR) is a recently defined phenotype of FTR associated with persistent/permanent atrial fibrillation. Differently from the classical ventricular form of FTR (V-FTR), patients with A-FTR might present with severely dilated right atrium (RA) and tricuspid annulus (TA), and with preserved right ventricular (RV) size and systolic function. However, the geometry and function of the RV, RA, and TA in patients with A-FTR and V-FTR remain to be systematically evaluated. Accordingly, we sought to: (i) study the geometry and function of the RV, RA, and TA in A-FTR by two- and three-dimensional transthoracic echocardiography and (ii) compare them with those found in V-FTR. Methods and results We prospectively analysed 113 (44 men, age 68 ± 18 years) FTR patients (A-FTR = 55 and V-FTR = 58) that were compared to two groups of age- and sex-matched controls to develop the respective Z-scores. Severity of FTR was similar in A-FTR and V-FTR patients. Z-scores of RV size were significantly larger, and those of RV function were significantly lower in V-FTR than in A-FTR (P &lt; 0.001 for all). The RA was significantly enlarged in both A-FTR and V-FTR compared to controls (P &lt; 0.001, Z-scores &gt; 2), with similar RA maximal volume (RAVmax) between A-FTR and V-FTR (P = 0.2). Whereas, the RA minimal volumes (RAVmin) were significantly larger in A-FTR than in V-FTR (P = 0.001). Conclusions Despite similar degrees of FTR, and RAVmax size, A-FTR patients show a larger RAVmin, and smaller TA areas than V-FTR patients. Conversely, V-FTR patients show dilated, more elliptic, and dysfunctional RV than A-FTR patients.

Abstract Aims  We sought to investigate tricuspid valve (TV) geometry and right heart remodelling in atrial functional tricuspid regurgitation (AF-TR) as compared with ventricular functional TR with sinus rhythm (VF-TR). Methods and results  Transoesophageal 3D echocardiography datasets of the TV and right ventricle were acquired in 51 symptomatic patients with severe TR (AF-TR, n = 23; VF-TR, n = 28). Three-dimensional right ventricular (RV) endocardial surfaces were reconstructed throughout the cardiac cycle and then postprocessed using semiautomated integration and segmentation software to calculate position of papillary muscle (PM) tips. Compared with VF-TR, AF-TR had more dilated and posteriorly displaced annulus and less leaflet tethering angles with more prominent right atrium and smaller RV end-systolic volume. On the XY (annular) plane, the centre of annulus was getting closer towards the anterior and posterior PM tips and was going away from the medial PM tip caused by prominent annular dilatation in AF-TR. On the Z-axis, the position of each PM tip in AF-TR was not so much displaced apically as that in VF-TR. Multiple linear regression analyses revealed that right atrial volume and right atrial/RV end-systolic volume ratio were determinants of annular area and orientation in AF-TR, respectively (both P &lt; 0.001). Additionally, the posteromedial-directed component of posterior PM tip position and the apically directed component of the position of all three PM tips were independently associated with TV tethering angles of each leaflet in AF-TR (all P &lt; 0.02). Conclusion  Right heart remodelling and its association with 3D TV geometry differ entirely between AF-TR and VF-TR, which may offer distinctive therapeutic implication.
