First-in-human transcatheter pledget-assisted suture tricuspid annuloplasty for severe tricuspid insufficiency.

ABSTRACT:

Objectives

We report the first pledget-assisted suture tricuspid annuloplasty (PASTA) in a patient with torrential tricuspid regurgitation (TR).

Background

Tricuspid valve regurgitation is a common malignant disease with no commercially available transcatheter therapy. PASTA is a "percutaneous surgical" procedure using pledgeted sutures to create a double-orifice tricuspid valve.

Methods

An 83-year-old man had end-stage TR caused by a defibrillator lead. He consented to undergo PASTA on a compassionate basis. A double-orifice valve was created with pledgeted sutures from percutaneous right ventricular apical access.

Results

TR was reduced from torrential to trace. The vena contracta reduced to from 23 to 1 mm and annular area reduced from 1817 to 782 mm² . However, the annulus dehisced and required closure with a percutaneous nitinol plug. The patient was discharged home and was alive 6 months later but with persistent symptoms.

Conclusions

The anatomy of a double-orifice valve can eliminate TR but a better solution is required to avoid excessive suture tension on annular tissue.

Transcatheter pledget-assisted suture tricuspid annuloplasty (PASTA) to create a double-orifice valve.

Project description:OBJECTIVES:Pledget-assisted suture tricuspid valve annuloplasty (PASTA) is a novel technique using marketed equipment to deliver percutaneous trans-annular sutures to create a double-orifice tricuspid valve. BACKGROUND:Tricuspid regurgitation is a malignant disease with high surgical mortality and no commercially available transcatheter solution in the US. METHODS:Two iterations of PASTA were tested using trans-apical or trans-jugular access in swine. Catheters directed paired coronary guidewires to septal and lateral targets on the tricuspid annulus under fluoroscopic and echocardiographic guidance. Guidewires were electrified to traverse the annular targets and exchanged for pledgeted sutures. The sutures were drawn together and knotted, apposing septal and lateral targets, creating a double orifice tricuspid valve. RESULTS:Twenty-two pigs underwent PASTA. Annular and chamber dimensions were reduced (annular area, 10.1?±?0.8 cm2 to 3.8?±?1.5 cm2 (naïve) and 13.1?±?1.5 cm2 to 6.2?±?1.0 cm2 (diseased); septal-lateral diameter, 3.9?±?0.3 mm to 1.4?±?0.6 mm (naïve) and 4.4?±?0.4 mm to 1.7?±?1.0 mm (diseased); and right ventricular end-diastolic volume, 94?±?13 ml to 85?±?14 ml (naïve) and 157?±?25 ml to 143?±?20 ml (diseased)). MRI derived tricuspid regurgitation fraction fell from 32?±?12% to 4?±?5%. Results were sustained at 30 days. Pledget pull-through force was five-fold higher (40.6?±?11.7N vs 8.0?±?2.6N, P?<?.01) using this strategy compared to single puncture techniques used to anchor current investigational devices. Serious complications were related to apical access. CONCLUSIONS:PASTA reduces annular dimensions and tricuspid regurgitation in pigs. It may be cautiously applied to selected patients with severe tricuspid regurgitation and no options. This is the first transcatheter procedure, to our knowledge, to deliver standard pledgeted sutures to repair cardiac pathology.

Hemodynamic outcomes after undersizing ring annuloplasty and focal suture annuloplasty for surgical repair of functional tricuspid regurgitation.

Project description:ObjectiveSurgical annuloplasty for functional tricuspid regurgitation (FTR) is on the rise and can be performed in several ways with varied outcomes. In this study, we sought to compare the hemodynamic outcomes of tricuspid annuloplasty performed with a commercially available annuloplasty ring (tricuspid valve annuloplasty [TVA]) compared with focal suture annuloplasty (Hetzer) in an experimental FTR model.MethodsAn ex vivo FTR model was developed by inducing right ventricular dilatation by acute afterload elevation, causing severe tricuspid valve tethering and annular dilatation, leading to regurgitation. Ten porcine hearts in which FTR was induced underwent TVA with a 26-mm Edwards MC3 ring and Hetzer annuloplasty with a pledgeted suture cinching the anteroposterior and septal annulus. FTR was measured before after each repair, and tenting geometry, valve kinematics, and subvalvular geometry were measured with echocardiography.ResultsAt baseline, none of the hearts had FTR, but upon afterload elevation an FTR volume of 17.7 ± 9.2 mL (26.38 ± 17.47% regurgitant fraction) was measured (P < .0001). TVA reduced regurgitation by 50% and Hetzer annuloplasty by 56% , respectively, but both left persistent FTR. Anteroseptal tenting area was 279.0 ± 158.9 mm2 before repair and decreased significantly to 147.2 ± 134.8 mm2 (P = .0195) with Hetzer but not with TVA. Posteroseptal tenting area was 425.1 ± 169.2 mm2 before repair and was significantly reduced by both techniques (TVA: 200.3 ± 102.9 mm2 [P = .0012]; Hetzer: 237.6 ± 127.6 mm2 [P = .0270]).ConclusionsTricuspid annuloplasty with a ring or a focal suture can reduce FTR but not eliminate it. Annular approaches did not relieve tricuspid valve tethering and reduced leaflet mobility persisted. Either subannular repairs or judicious use of valve replacement may be necessary.

Feasibility Study of a Novel Transcatheter Tricuspid Annuloplasty System in a Porcine Model.

Project description:Gradually, more attention has been paid to tricuspid regurgitation. Formerly the "forgotten valvular heart disease," it has been recognized as having high incidence and adverse prognosis if untreated. However, isolated tricuspid valve surgery carries substantial risk and is thus not recommended. The K-Clip transcatheter tricuspid annuloplasty system has recently emerged as a minimally invasive therapeutic option that may help address these unmet clinical needs. The K-Clip technology simulates the Kay's procedure, which reduces the dimensions of the tricuspid annulus by folding and clamping the tricuspid annulus issue with a rigid clamping device. The feasibility of the K-Clip technology was investigated in this study, and annulus area reduction and declining tricuspid regurgitation grades were noted following the procedure. The findings of this study suggest that the K-Clip system may potentially be applicable as a novel transcatheter tricuspid annuloplasty device for the treatment of severe tricuspid in humans.

Transatrial intrapericardial tricuspid annuloplasty.

Project description:OBJECTIVES:This study sought to demonstrate transcatheter deployment of a circumferential device within the pericardial space to modify tricuspid annular dimensions interactively and to reduce functional tricuspid regurgitation (TR) in swine. BACKGROUND:Functional TR is common and is associated with increased morbidity and mortality. There are no reported transcatheter tricuspid valve repairs. We describe a transcatheter extracardiac tricuspid annuloplasty device positioned in the pericardial space and delivered by puncture through the right atrial appendage. We demonstrate acute and chronic feasibility in swine. METHODS:Transatrial intrapericardial tricuspid annuloplasty (TRAIPTA) was performed in 16 Yorkshire swine, including 4 with functional TR. Invasive hemodynamics and cardiac magnetic resonance imaging (MRI) were performed at baseline, immediately after annuloplasty and at follow-up. RESULTS:Pericardial access via a right atrial appendage puncture was uncomplicated. In 9 naïve animals, tricuspid septal-lateral and anteroposterior dimensions, the annular area and perimeter, were reduced by 49%, 31%, 59%, and 24% (p < 0.001), respectively. Tricuspid leaflet coaptation length was increased by 53% (p < 0.001). Tricuspid geometric changes were maintained after 9.7 days (range, 7 to 14 days). Small effusions (mean, 46 ml) were observed immediately post-procedure but resolved completely at follow-up. In 4 animals with functional TR, severity of regurgitation by intracardiac echocardiography was reduced. CONCLUSIONS:Transatrial intrapericardial tricuspid annuloplasty is a transcatheter extracardiac tricuspid valve repair performed by exiting the heart from within via a transatrial puncture. The geometry of the tricuspid annulus can interactively be modified to reduce severity of functional TR in an animal model.

Tricuspid Valve Annuloplasty Alters Leaflet Mechanics.

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.

Comparing outcomes of transcatheter tricuspid valve replacement and medical therapy for symptomatic severe tricuspid regurgitation: a retrospective study.

Project description:BackgroundImpaired hospitalizations for heart failure (HHF) and mortality are associated with tricuspid regurgitation (TR).ObjectivesThe objective of this study was to investigate the benefit of transcatheter tricuspid valve replacement (TTVR) over guideline-directed medical therapy (GDMT) in patients with symptomatic severe TR.MethodsBetween May 2020 and April 2023, 88 patients with symptomatic severe TR were treated in our center. Of these, 57 patients received GDMT alone, and 31 patients underwent combined TTVR and GDMT. We collected and analyzed baseline data, and follow-up information for both groups. The primary endpoints were all-cause mortality and the combined endpoint (including all-cause mortality and HHF).ResultsAt a median follow-up of 20 (IQR 10-29) months, significant improvements were shown in TR severity, right ventricular function, and dimensions in TTVR group (all P < 0.001). It also resulted in superior survival rates (75.8% vs. 48.4%, P = 0.019), improved freedom from combined endpoint (61.5% vs. 45.9%, P = 0.007) and fewer major adverse events. After stratification by TRI-SCORE, the subgroup with < 6 points in the TTVR group exhibited a significant difference in the combined endpoint compared to the other subgroups (all P < 0.05), while no significant differences were observed in the GDMT subgroups (P = 0.680).ConclusionsThe utilization of LuX-Valve in TTVR effectively improves TR and is associated with lower rates of major adverse events, HHF and all-cause mortality. The TRI-SCORE may help identify higher-benefit patients with TR from TTVR. Clinical trial registration ClinicalTrials.gov Protocol Registration System (NCT02917980).
