Severe tricuspid regurgitation is associated with disabling symptoms and an increased risk of death. Data regarding outcomes after percutaneous transcatheter tricuspid-valve replacement are needed. In this international, multicenter trial, we randomly assigned 400 patients with severe symptomatic tricuspid regurgitation in a 2:1 ratio to undergo either transcatheter tricuspid-valve replacement and medical therapy (valve-replacement group) or medical therapy alone (control group). The hierarchical composite primary outcome was death from any cause, implantation of a right ventricular assist device or heart transplantation, postindex tricuspid-valve intervention, hospitalization for heart failure, an improvement of at least 10 points in the score on the Kansas City Cardiomyopathy Questionnaire overall summary (KCCQ-OS), an improvement of at least one New York Heart Association (NYHA) functional class, and an improvement of at least 30 m on the 6-minute walk distance. A win ratio was calculated for the primary outcome by comparing all possible patient pairs, starting with the first event in the hierarchy. A total of 267 patients were assigned to the valve-replacement group and 133 to the control group. At 1 year, the win ratio favoring valve replacement was 2.02 (95% confidence interval [CI], 1.56 to 2.62; P<0.001). In comparisons of patient pairs, those in the valve-replacement group had more wins than the control group with respect to death from any cause (14.8% vs. 12.5%), postindex tricuspid-valve intervention (3.2% vs. 0.6%), and improvement in the KCCQ-OS score (23.1% vs. 6.0%), NYHA class (10.2% vs. 0.8%), and 6-minute walk distance (1.1% vs. 0.9%). The valve-replacement group had fewer wins than the control group with respect to the annualized rate of hospitalization for heart failure (9.7% vs. 10.0%). Severe bleeding occurred in 15.4% of the valve-replacement group and in 5.3% of the control group (P = 0.003); new permanent pacemakers were implanted in 17.4% and 2.3%, respectively (P<0.001). For patients with severe tricuspid regurgitation, transcatheter tricuspid-valve replacement was superior to medical therapy alone for the primary composite outcome, driven primarily by improvements in symptoms and quality of life.

Among patients with at least moderate functional mitral regurgitation, transcatheter valve repair led to a lower rate of heart failure events during 24 months and better health status at 12 months than medical therapy alone.

In a randomized trial, patients with tricuspid regurgitation who were treated with transcatheter edge-to-edge repair had more favorable clinical outcomes at 1 year than did patients who received medical therapy.

Transcatheter repair of secondary mitral regurgitation was associated with a lower rate of hospitalization for heart failure and lower all-cause mortality than medical therapy at 5 years of follow-up.

Placement of an interatrial shunt device reduces pulmonary capillary wedge pressure during exercise in patients with heart failure and preserved or mildly reduced ejection fraction. We aimed to investigate whether an interatrial shunt can reduce heart failure events or improve health status in these patients. In this randomised, international, blinded, sham-controlled trial performed at 89 health-care centres, we included patients (aged ≥40 years) with symptomatic heart failure, an ejection fraction of at least 40%, and pulmonary capillary wedge pressure during exercise of at least 25 mm Hg while exceeding right atrial pressure by at least 5 mm Hg. Patients were randomly assigned (1:1) to receive either a shunt device or sham procedure. Patients and outcome assessors were masked to randomisation. The primary endpoint was a hierarchical composite of cardiovascular death or non-fatal ischemic stroke at 12 months, rate of total heart failure events up to 24 months, and change in Kansas City Cardiomyopathy Questionnaire overall summary score at 12 months. Pre-specified subgroup analyses were conducted for the heart failure event endpoint. Analysis of the primary endpoint, all other efficacy endpoints, and safety endpoints was conducted in the modified intention-to-treat population, defined as all patients randomly allocated to receive treatment, excluding those found to be ineligible after randomisation and therefore not treated. This study is registered with ClinicalTrials.gov, NCT03088033. Between May 25, 2017, and July 24, 2020, 1072 participants were enrolled, of whom 626 were randomly assigned to either the atrial shunt device (n=314) or sham procedure (n=312). There were no differences between groups in the primary composite endpoint (win ratio 1·0 [95% CI 0·8–1·2]; p=0·85) or in the individual components of the primary endpoint. The prespecified subgroups demonstrating a differential effect of atrial shunt device treatment on heart failure events were pulmonary artery systolic pressure at 20W of exercise (pinteraction=0·002 [>70 mm Hg associated with worse outcomes]), right atrial volume index (pinteraction=0·012 [≥29·7 mL/m2, worse outcomes]), and sex (pinteraction=0·02 [men, worse outcomes]). There were no differences in the composite safety endpoint between the two groups (n=116 [38%] for shunt device vs n=97 [31%] for sham procedure; p=0·11). Placement of an atrial shunt device did not reduce the total rate of heart failure events or improve health status in the overall population of patients with heart failure and ejection fraction of greater than or equal to 40%.

Tricuspid regurgitation is a prevalent disease associated with high morbidity and mortality, with few treatment options. The aim of the TRILUMINATE trial is to evaluate the safety and effectiveness of TriClip, a minimally invasive transcatheter tricuspid valve repair system, for reducing tricuspid regurgitation. The TRILUMINATE trial is a prospective, multicentre, single-arm study in 21 sites in Europe and the USA. Patients with moderate or greater triscuspid regurgitation, New York Heart Association class II or higher, and who were adequately treated per applicable standards were eligible for enrolment. Patients were excluded if they had systolic pulmonary artery pressure of more than 60 mm Hg, a previous tricuspid valve procedure, or a cardiovascular implantable electronic device that would inhibit TriClip placement. Participants were treated using a clip-based edge-to-edge repair technique with the TriClip tricuspid valve repair system. Tricuspid regurgitation was graded using a five-class grading scheme (mild, moderate, severe, massive, and torrential) that expanded on the standard American Society of Echocardiography grading scheme. The primary efficacy endpoint was a reduction in tricuspid regurgitation severity by at least one grade at 30 days post procedure, with a performance goal of 35%, analysed in all patients who had an attempted tricuspid valve repair procedure upon femoral vein puncture. The primary safety endpoint was a composite of major adverse events at 6 months, with a performance goal of 39%. Patients were excluded from the primary safety analysis if they did not reach 6-month follow-up and did not have a major adverse event during previous follow-ups. The trial has completed enrolment and follow-up is ongoing; it is registered with ClinicalTrials.gov, number NCT03227757. Between Aug 1, 2017, and Nov 29, 2018, 85 patients (mean age 77·8 years [SD 7·9]; 56 [66%] women) were enrolled and underwent successful TriClip implantation. Tricuspid regurgitation severity was reduced by at least one grade at 30 days in 71 (86%) of 83 patients who had available echocardiogram data and imaging. The one-sided lower 97·5% confidence limit was 76%, which was greater than the prespecified performance goal of 35% (p<0·0001). One patient withdrew before 6-month follow-up without having had a major adverse event and was excluded from analysis of the primary safety endpoint. At 6 months, five (6%) of 84 patients experienced a major adverse event, which was less than the prespecified performance goal of 39% (p<0·0001). Single leaflet attachment occurred in five (7%) of 72 patients. No periprocedural deaths, conversions to surgery, device embolisations, or strokes occurred. At 6 months, all-cause mortality had occurred in four (5%) of 84 patients. The TriClip system appears to be safe and effective at reducing tricuspid regurgitation by at least one grade. This reduction could translate to significant clinical improvement at 6 months post procedure. Abbott.

Background. This prospective study compared the success rate and safety of a distal transradial artery (dTRA) approach to that of the conventional transradial artery (TRA) for coronary angiography or percutaneous coronary intervention. Methods. From January 2019 to April 2020, nine hundred consecutive patients (height < 190 cm) scheduled for coronary angiography or percutaneous coronary interventions were randomly and equally assigned to receive either dTRA or conventional TRA catheterization. Results. Successful access was achieved in 96.00% and 96.67% of the dTRA and conventional TRA groups, respectively (P=0.814). Compared with the TRA group, patients in the dTRA experienced significantly less hemostatic band removal time (150.5 ± 50.5 cf. 210.6 ± 60.5 min, P=0.032); minor bleeding of the access site (2.44% cf. 6.44%, P=0.038); hemostatic band cost (USD; 0.1 cf. 59.4, P=0); and postprocedural radial artery occlusion (1.56% cf. 3.78%, P=0.035). A lower body mass index was a higher risk factor for dTRA access failure (odds ratio = 0.79, P=0.024), with a cutoff of 22.04 kg/m2. Conclusion. Compared to conventional TRA, dTRA had a comparable high success rate, with fewer associated complications. Clinicians should use the dTRA with caution in patients with low body mass index.

Transcatheter aortic-valve replacement with a new self-expanding prosthesis was compared with surgical aortic-valve replacement in patients with aortic stenosis who were at high surgical risk. The rate of death from any cause at 1 year was lower in the TAVR group. Aortic stenosis is a debilitating disease in elderly persons that carries a dismal prognosis after symptom onset. 1 Although surgical aortic-valve replacement remains the standard treatment for aortic stenosis, 2 many patients are not suitable candidates for surgical replacement owing to an increased risk of death during surgery. 3 , 4 Transcatheter aortic-valve replacement (TAVR) with a balloon-expandable device improves survival, as compared with medical therapy, in patients with severe aortic stenosis who cannot undergo surgery. 5 Balloon-expandable TAVR and surgical aortic-valve replacement are associated with similar survival rates at 1 year among patients considered to be at high surgical risk, although the frequency of . . .

Objective Decision making for intervention in symptomatic aortic stenosis should balance the risks of surgery and of transcatheter aortic valve implantation (TAVI). We identified the factors associated with early mortality after TAVI and aimed to develop and validate a simple risk score. Methods A population of 3833 consecutive patients was randomly split into two cohorts comprising 2552 and 1281 patients, used respectively to develop and validate a scoring system predicting 30-day or in-hospital mortality. Results TAVI was performed using the Edwards Sapien prosthesis in 2551 (66.8%) patients and the Medtronic Corevalve in 1270 (33.2%). Approach was transfemoral in 2801 (73.4%) patients, transapical in 678 (17.8%), subclavian in 219 (5.7%) and other in 117 (3.1%). Early mortality was 10.0% (382 patients). A multivariate logistic model identified the following predictive factors of early mortality: age ≥90 years, body mass index <30 Kg/m2, New York Heart Association class IV, pulmonary hypertension, critical haemodynamic state, ≥2 pulmonary oedemas during the last year, respiratory insufficiency, dialysis and transapical or other (transaortic and transcarotid) approaches. A 21-point predictive score was derived. C-index was 0.67 for the score in the development cohort and 0.59 in the validation cohort. There was a good concordance between predicted and observed 30-day mortality rates in the development and validation cohorts. Conclusions Early mortality after TAVI is mainly related to age, the severity of symptoms, comorbidities and transapical approach. A simple score can be used to predict early mortality after TAVI. The moderate discrimination is however a limitation for the accurate identification of high-risk patients.
