Project description:Severe mitral regurgitation and stenosis due to failed mitral annuloplasty ring can be managed with percutaneous mitral valve in ring in high surgical risk patients. A 66-year-old male underwent coronary artery bypass surgery and mitral valve ring annuloplasty 7 years previously. He started to have shortness of breath with minimal effort in the past 2 years. Transthoracic echocardiogram revealed a new severe mitral regurgitation and severe mitral stenosis. The patient was turned down from surgery due to high surgical risk. The transcatheter mitral valve in ring implantation was decided. In this case, there was a low probability of left ventricular outflow tract obstruction. A stiff wire crossed the mitral valve ring and positioned in the left ventricular apex. The Sapien 3 valve size 26 mm (Edwards Lifesciences, Irvine, CA, USA) was positioned to have 80% ventricular and 20% atrial side. Transesophageal echocardiogram evaluation revealed a mean gradient of 5 mmHg. The left ventricular outflow tract (LVOT) had laminar color flow and the mean pressure gradient across LVOT was 1 mmHg. The patient was discharged after 2 days in good condition. At one year follow up, he had no shortness of breath and no rehospitalization. In conclusion, the percutaneous mitral valve in ring is feasible in selected patients. The risk of LVOT obstruction should be assessed carefully before the procedure with a transthoracic and transesophageal echocardiogram. 〈Learning objective: Understand how to guide the mitral valve in ring procedure with a transesophageal echocardiogram and how to avoid left ventricular outflow tract obstruction. Understand how to position the Sapien valve in mitral valve ring.〉.

Project description:Transcatheter tricuspid valve intervention (TTVI) is a novel alternative to functional tricuspid regurgitation (FTR) for patients with prohibitive surgical risk. Devices have been designed according to different pathophysiological mechanisms of FTR, including ones to achieve an edge-to-edge repair and others aiming at direct annuloplasty. Recently, a transcatheter tricuspid valve repair system mimicking a surgical Kay procedure (K-Clip™ system, Huihe Medical Technology, Shanghai, China) completed its salvage-use trial. The system, which clips the posterior annulus to achieve bicuspidization of the TV, demonstrated acceptable procedural safety and efficacy. Each TTVI system has distinct characteristics for echocardiographic imaging and special consideration for intraoperative guidance. This review focuses on elaborating how two-dimensional and three-dimensional transesophageal echocardiography (TEE) are used in clinical practice to guide K-Clip™ implantation in comparison to other direct annular reduction devices. A limited number of TEE work planes are proposed for the procedure with the aim to provide a steeper learning curve for the echocardiographer and interventionalist while simplifying the implantation steps.

Project description:Tricuspid valve disease has been neglected for a long time by cardiologists and surgeons, but for some years now leakage of tricuspid valve has been demonstrated as a prognostic factor in the evolution of patients with left heart valve disease undergoing surgery. Several techniques for plastic repair of tricuspid valve have been developed and the published studies differ on the results of these techniques; we conducted this study to assess the results of plastic repair of tricuspid valve in a population of patients with a high prevalence of rheumatic disease and to compare Carpentier's ring annuloplasty techniques with DEVEGA plasty. We conducted a retrospective study of patients undergoing plastic repair of tricuspid valve in the Department of Cardiology at the Medicine University of Sfax over a period of 25 years. We compared the results from the Group 1 (Carpentier's ring annuloplasty) with Group 2 (DeVEGA plasty). 91 patients were included in our study, 45 patients in the Group 1 and 46 patients in the Group 2. Most patients had mean or severe TI (83%) before surgery, ring dilation was observed in 90% of patients with no significant difference between the two groups. Immediate results were comparable between the two techniques but during monitoring recurrent, at least mean, insufficiency was significantly more frequent in the DeVEGA plasty Group. The predictive factors for significant recurring long term TI were DeVEGA technique (OR=3.26[1.12-9.28]) in multivariate study and preoperative pulmonary artery systolic pressure (OR=1.06 (1.01-1.12)). Plastic repair of tricuspid valve using Carpentier's ring seems to guarantee better results than DeVEGA plasty. On the other hand, preoperative high PASP is predictive of recurrent leakage of tricuspid valve even after plasty; hence the importance of surgery in the treatment of patients at an early stage of the disease.

Project description:AimsWe sought to investigate the additional value of real-time three-dimensional transoesophageal echocardiography (RT 3D TOE)-guided sizing for predicting annuloplasty ring size during mitral valve repair.Methods and resultsIn 53 patients undergoing elective mitral valve repair, an RT 3D TOE was performed pre- and post-operatively. The digitally stored loops were imported into a software for mitral valve assessment. The annuloplasty ring size was predicted by superimposing computer-aided design (CAD) models of annuloplasty rings onto Live 3D zoom loops, measurement of the intercommissural distance, or the height of the anterior mitral leaflet. The surgeon implanted the annuloplasty ring according to the usual surgical technique and was blinded to the echocardiographic measurement results. Pre-operative correlation between the selected ring size with mitral valve assessment and the actual implanted annuloplasty ring size was 0.91. The correlation for measurement of the intercommissural distance was 0.55 and for measurement of the height of the anterior mitral leaflet 0.75. The post-operative correlation with the actual implanted ring size was 0.96 for mitral valve assessment, 0.92 for intercommissural distance, and 0.79 for the anterior mitral leaflet height.ConclusionSuperimposition of annuloplasty ring CAD models on the Live 3D zoom loops of the mitral valve using mitral valve assessment is superior to two-dimensional measurements of the intercommissural distance or the height of the anterior mitral leaflet in predicting correct annuloplasty ring size.

Project description:Tricuspid valve regurgitation is associated with significant morbidity and mortality. Its most common treatment option, tricuspid valve annuloplasty, is not optimally effective in the long-term. Toward identifying the causes for annuloplasty's ineffectiveness, we have previously investigated the technique's impact on the tricuspid annulus and the right ventricular epicardium. In our current work, we are extending our analysis to the anterior tricuspid valve leaflet. To this end, we adopted our previous strategy of performing DeVega suture annuloplasty as an experimental methodology that allows us to externally control the degree of cinching during annuloplasty. Thus, in ten sheep we successively cinched the annulus and quantified changes to leaflet motion, dynamics, and strain in the beating heart by combining sonomicrometry with our well-established mechanical framework. We found that successive cinching of the valve enforced earlier coaptation and thus reduced leaflet range of motion. Additionally, leaflet angular velocity during opening and closing decreased. Finally, we found that leaflet strains were also reduced. Specifically, radial and areal strains decreased as a function of annular cinching. Our findings are critical as they suggest that suture annuloplasty alters the mechanics of the tricuspid valve leaflets which may disrupt their resident cells' mechanobiological equilibrium. Long-term, such disruption may stimulate tissue maladaptation which could contribute to annuloplasty's sub-optimal effectiveness. Additionally, our data suggest that the extent to which annuloplasty alters leaflet mechanics can be controlled via degree of cinching. Hence, our data may provide direct surgical guidelines.

Project description:ObjectivesThe Tri-Ad Adams tricuspid annuloplasty ring is a recent innovative prosthesis characterized by a semi-rigid central component and fully flexible extremities. The goal of this study was to assess the short-term and mid-term results following implantation of the Tri-Ad Adams ring.MethodsA retrospective analysis was conducted on patients who underwent tricuspid annuloplasty using the Tri-Ad Adams ring between August 2016 and October 2021.ResultsOur study enrolled a total of 248 participants. The median age was 64.0 (interquartile range: 56.0-71.5) years. The median EuroSCORE II was 4.3% (2.7-7.5%), with 37 patients (14.9%) having a history of cardiac operations. Tricuspid regurgitation of grade 2-3 was observed in 63.7% of cases, and the median tricuspid annular diameter was 3.3 (2.8-3.6) cm. Concurrent procedures included mitral valve replacement (n = 160, 64.5%), mitral valve repair (n = 75, 30.2%), aortic valve replacement (n = 72, 29.0%) and the maze procedure (n = 170, 68.5%). Immediate postoperative tricuspid regurgitation≥moderate was present in 1 patient (0.4%). Early death occurred in 14 patients (5.6%). Major complications included low cardiac output syndrome (n = 18, 0.3%), acute kidney injury (n = 14, 5.6%) and permanent pacemaker placement (n = 15, 6.0%). According to the Kaplan-Meier analysis, the 4-year rates of freedom from overall mortality and moderate-to-severe tricuspid regurgitation were 96.9% and 91.6%, respectively. There were no incidents of tricuspid valve reoperations, ring detachment or significant tricuspid stenosis (trans-tricuspid valve gradient ≥ 5 mmHg).ConclusionsTricuspid annuloplasty utilizing the Tri-Ad Adams ring demonstrated favourable outcomes in both the early and midterm periods. Further studies are warranted to confirm the long-term results.
