Project description:BackgroundTranscatheter tricuspid valve intervention has recently emerged as a viable alternative to surgery for patients with symptomatic severe tricuspid regurgitation (TR). Though usually performed on the basis of compassionate grounds, we are now exploring the extension of its usage as an elective option in a patient with severe atrial functional tricuspid regurgitation.AimsThe aim of this study was to select a suitable patient and proceed with the implantation of the TricValve in order to provide symptomatic relief as well as to improve morbidity and mortality.MethodsA 67-year-old woman had underlying atrial fibrillation and severe tricuspid regurgitation. Despite optimised medical therapy, she remained symptomatic with elevated NT-proBNP levels. As the patient refused surgery on multiple occasions, we chose a percutaneous procedure guided by transoesophageal echocardiography and fluoroscopy.ResultsThe procedure was uneventful and the patient was discharged. At 3-month follow-up, there was marked improvement clinically and biochemically.ConclusionsBicaval valve implantation with the TricValve is a viable alternative to surgery in patients with symptomatic severe tricuspid regurgitation. This intervention is crucial as we are now able to intervene before irreversible right ventricular dysfunction sets in.

Project description:Severe tricuspid regurgitation remains a challenging heart-valve disease to effectively treat with high morbidity and mortality at mid-term. Currently guideline-directed medical treatment is limited to escalating dose of diuretics, and the rationale and timing of open-heart surgery remains controversial. Emerging percutaneous therapies for severe tricuspid regurgitation continue to show promising results in early feasibility studies. However, randomized trial data is lacking. Additionally, many patients are deemed unsuitable for these emerging therapies due to anatomical or imaging constraints. Given the technical simplicity of the bicaval valve implantation (CAVI) technique compared to other transcatheter devices, CAVI is postulated as a suitable alternative for a wide variety of patients affected with severe+ tricuspid regurgitation. In this review we illustrate the current evidence and ongoing uncertainties of CAVI, focusing on the novel CAVI-specific devices.

Project description:BackgroundSevere tricuspid regurgitation (TR) is a complex condition that can be difficult to treat medically, and often surgical intervention is prohibited due to the high morbidity and mortality associated with this intervention. In patients who have failed maximal medical therapy and have progressive symptoms related to their severe TR, heterotopic caval valve implantation (CAVI) offers potential for symptom relief for these patients.Case summaryWe present two cases of patients with severe TR with symptoms of heart failure that were refractory to medical therapy. Due to extensive comorbidities in these patient's surgical intervention was deemed unsuitable and the decision was made to proceed with heterotopic CAVI in order to try and control their symptoms. Both patients successfully underwent the procedure and had an Edwards SAPIEN 3 valve (Edwards Lifesciences, Irvine, CA, USA) implanted in the inferior vena cava/right atrium junction. In both patients, there was improvement in the postoperative haemodynamics as measured by invasive and non-invasive methods. Successful discharge was achieved in both patients with improvement in their symptoms.DiscussionSelective use of heterotopic CAVI to treat symptomatic severe TR that is refractory to medical therapy may be a viable option to improve symptoms in those patients that are unsuitable for surgical intervention.

Project description:Due to progressive abdominal-venous congestion severe tricuspid regurgitation (TR) is a common cause of cardiorenal and cardiohepatic syndrome. We initiated the TRICAVAL study to compare interventional valve implantation into the inferior vena cava (CAVI) versus optimal medical therapy (OMT) in severe TR. In the present subanalysis, we aimed to evaluate the effects of CAVI on clinical signs of congestion, renal and hepatic function. TRICAVAL was an investigator-initiated, randomized trial. Twenty-eight patients with severe TR were randomized to OMT or CAVI using an Edwards Sapien XT valve. Probands who completed the 3-month follow-up (CAVI [n = 8], OMT [n = 10]) were evaluated by medical history, clinical examination, and laboratory testing at baseline, 3 and 12 months. After 3 months, the CAVI group exhibited a significant reduction of body weight (from 80.7 [69.0-87.7] kg to 75.5 [63.8-84.6] kg, p < 0.05) and abdominal circumference (from 101.5 ± 13.8 cm to 96.3 ± 15.4 cm, p ≤ 0.01) and a trend to lower doses of diuretics compared to OMT. Renal and hepatic function parameters did not change significantly. Within a short-term follow-up, CAVI led to an improvement of clinical signs of venous congestion and a non-significant reduction of diuretic doses compared to OMT.

Project description: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). 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. 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. 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.

Project description:Untreated tricuspid valve regurgitation (TR) is associated with increased rates of mortality, morbidity, and hospitalization. Current pharmacological and surgical treatment options for TR are limited. MitraClip (MC), an edge-to-edge percutaneous intervention, has been reported to be effective for treatment of TR. The goal of this study was to examine the effects of MC position on TR, using a multiphysics fluid-structure-interaction (FSI) analysis. The computational set up included the tricuspid valve (TV), the chordae tendineae, the blood particles, and a tube that surrounded the leaflets and blood particles. The leaflets and chordae were modeled as hyperelastic materials, and blood was modeled using smoothed particle hydrodynamics. FSI analysis was conducted for blood flow through the closed valve for multiple simulations that account for normal, diseased, and treated conditions of the TV. To simulate the diseased TV, a group of chordae between septal and pulmonary leaflets were removed from the normal TV, which produced increased regurgitation. Four MC treated scenarios were considered: i) one MC near the annulus, ii) one MC approximately midway between the annulus and leaflet tip, iii) one MC near the leaflet tip, iv) two MCs: one approximately midway between the annulus and leaflet tip, and one close to the leaflet tip. The TR increased in diseased TV (7.5%) compared to normal TV (2.5%). All MC treated scenarios decreased TR. The MC located near the midway point between the annulus and leaflet tip led to largest decrease in TR (75.2% compared to the untreated condition). The MC located near the leaflet tip was associated with lowest reduction in TR (2.2% compared to the untreated condition). When two MCs were used, reduction in TR was relatively high (68.7%), but TR was not improved compared to the optimal single MC. MC caused high stresses in the vicinity of the clipping area in all conditions; the highest occurred when the MC was near the leaflet tips. Using a quantitative computational approach, we confirm previous clinical reports on the efficacy of MC for treatment of TR. The results of this study could lead to the design of more efficient MC interventions for TR.
