Aims: Patients with pulmonary hypertension (PHT) are often excluded from surgical therapies for tricuspid regurgitation (TR). Transcatheter tricuspid valve repair (TTVR) with the MitraClip™ technique is a novel treatment option for these patients. We aimed to assess the role of PHT in severe TR and its implications for TTVR. Methods and results: A total of 243 patients underwent TTVR at two centres. One hundred twenty-one patients were grouped as iPHT+ [invasive systolic pulmonary artery pressures (PAPs) ≥50 mmHg]. Patients were similarly stratified according to echocardiographic PAPs (ePHT). The occurrence of the combined clinical endpoint (death, heart failure hospitalization, and reintervention) was investigated during a follow-up of 330 (interquartile range 175–402) days. iPHT+ patients were at higher preoperative risk (P < 0.01), had more severe symptoms (P = 0.01), higher N-terminal pro-B-type natriuretic peptide levels (P < 0.01), more impaired right ventricular (RV) function (P < 0.01), and afterload corrected RV function (P < 0.01). Procedural TTVR success was similar in iPHT+ and iPHT− patients (84 vs. 84%, P = 0.99). The echocardiographic diagnostic accuracy to detect iPHT was only 55%. During follow-up, 35% of patients reached the combined clinical endpoint. The discordant diagnosis of iPHT+/ePHT− carried the highest risk for the combined clinical endpoint [HR 3.76 (CI 2.25–6.37), P < 0.01], while iPHT+/ePHT+ patients had a similar survival-free time from the combined endpoint compared to iPHT− patients (P = 0.48). In patients with isolated tricuspid procedure (n = 131) a discordant iPHT+/ePHT− diagnosis and an impaired afterload corrected RV function (P < 0.01 for both) were independent predictors for the occurrence of the combined endpoint. Conclusion: The discordant echocardiographic and invasive diagnosis of PHT in severe TR predicts outcomes after TTVR.

Aims: The impact of sexuality in patients with significant tricuspid regurgitation (TR) undergoing transcatheter tricuspid valve intervention (TTVI) is unknown. The aim of this study was to investigate sex-specific outcomes in patients with significant TR treated with TTVI vs. medical therapy alone.Methods and results: The Transcatheter Tricuspid Valve Therapies (TriValve) registry collected data on patients with significant TR from 24 centres who underwent TTVI from 2016 to 2021. A control cohort was formed by medically managed patients with ≥severe isolated TR diagnosed in 2015–18. The primary endpoint was freedom from all-cause mortality. Secondary endpoints were heart failure (HF) hospitalization, New York Heart Association (NYHA) functional status, and TR severity. One-year outcomes were assessed for the TriValve cohort and compared with the control cohort with the inverse probability of treatment weighting (IPTW). A total of 556 and 2072 patients were included from the TriValve and control groups, respectively. After TTVI, there was no difference between women and men in 1-year freedom from all-cause mortality 80.9% vs. 77.9%, P = 0.56, nor in HF hospitalization (P = 0.36), NYHA Functional Classes III and IV (P = 0.17), and TR severity >2+ at last follow-up (P = 0.42). Multivariable Cox-regression weighted by IPTW showed improved 1-year survival after TTVI compared with medical therapy alone in both women (adjusted hazard ratio 0.45, 95% confidence interval 0.23–0.83, P = 0.01) and men (adjusted hazard ratio 0.42, 95% confidence interval 0.18–0.89, P = 0.03).Conclusion: After TTVI in high-risk patients, there were no sex-related differences in terms of survival, HF hospitalization, functional status, and TR reduction up to 1 year. The IPTW analysis shows a survival benefit of TTVI over medical therapy alone in both women and men.

Objectives: We investigated the durability of tricuspid regurgitation (TR) reduction and the clinical outcomes through 12 months after transcatheter tricuspid valve repair (TTVr) with the PASCAL Transcatheter Valve Repair System.Background: TTVr has rapidly developed and demonstrated favorable acute outcomes, but longer follow‐up data are needed.Methods: Overall, 30 patients (age 77 ± 6 years; 57% female) received PASCAL implantation from September 2017 to May 2019 and completed a clinical follow‐up at 12 months.Results: The TR etiology was functional in 25 patients (83%), degenerative in three (10%), and mixed in two (7%). All patients had TR severe or greater (massive or torrential in 80%) and heart failure symptoms (90% in NYHA III or IV) under optimal medical treatment. Single‐leaflet device attachment occurred in two patients. Moderate or less TR was achieved in 23/28 patients (82%) at 30 days, which was sustained at 12 months (86%). Two patients underwent repeat TTVr due to residual torrential TR (day 173) and recurrence of severe TR (day 280), respectively.One‐year survival rate was 93%; 6 patients required rehospitalization due to acute heart failure. NYHA functional class I or II was achieved in 90% and 6‐minute walk distance improved from 275 ± 122 m at baseline to 347 ± 112 m at 12‐month (+72 ± 82 m, p < .01). There was no stroke, endocarditis, or device embolization during the follow‐up.Conclusions: Twelve‐month outcomes from this multicenter compassionate use experience with the PASCAL System demonstrated high procedural success, acceptable safety, and significant clinical improvement.

The number of patients treated with the mechanical circulatory support device Impella Cardiac Power (CP) for cardiogenic shock is steadily increasing. The aim of this study was to investigate long-term survival and complications related to this modality. Patients undergoing Impella CP treatment for cardiogenic shock were retrospectively enrolled and matched with cardiogenic shock patients not treated with mechanical circulatory support between 2010 and 2020. Data were collected from the cardiogenic shock registry of the university hospital of Munich (DRKS00015860). 70 patients with refractory cardiogenic shock without mechanical circulatory support were matched with 70 patients treated with Impella CP. At presentation, the mean age was 67 ± 15 years with 80% being male in the group without support and 67 ± 14 years (p = 0.97) with 76% being male (p = 0.68) in the group with Impella. There was no significant difference in the rate of cardiac arrest (47% vs. 51%, p = 0.73) and myocardial infarction was the predominant cause of cardiogenic shock in both groups (70% vs. 77%). A total of 41% of patients without cardiocirculatory support and 54% of patients with Impella support died during the first month (p = 0.17). After one year, mortality rates were similar in both groups (55% in conventional vs. 59% in Impella CP group, p = 0.30) as was mortality rate at long-term 5-years follow-up (64% in conventional vs. 73% in Impella CP group, p = 0.33). The rate of clinically significant bleedings during ICU stay was lower in the conventional group than in the Impella support group (15% vs. 43%, p = 0.002). In this small observational and non-randomized analysis no difference in long-term outcome between patients treated with Impella CP vs. guideline directed cardiogenic shock therapy without mechanical circulatory support could be detected. Care must be taken regarding the high rate of bleeding and vascular complications when using Impella CP. Large, adequately powered studies are urgently needed to investigate the efficacy and safety of Impella CP in cardiogenic shock.
