RESUMO

AIMS: The impact of the cardio-hepatic syndrome (CHS) on outcomes in patients undergoing mitral valve transcatheter edge-to-edge repair (M-TEER) for relevant mitral regurgitation (MR) is unknown. The objectives of this study were three-fold: (i) to characterize the pattern of hepatic impairment, (ii) to investigate the prognostic value of CHS, and (iii) to evaluate the changes in hepatic function after M-TEER. METHODS AND RESULTS: Hepatic impairment was quantified by laboratory parameters of liver function. In accordance with existing literature, two types of CHS were distinguished: ischaemic type I CHS (elevation of both transaminases) and cholestatic type II CHS (elevation of two out of three parameters of hepatic cholestasis). The impact of CHS on 2-year mortality was evaluated using a Cox model. The change in hepatic function after M-TEER was assessed by laboratory testing at follow-up. We analysed 1083 patients who underwent M-TEER for relevant primary or secondary MR at four European centres between 2008 and 2019. Ischaemic type I and cholestatic type II CHS were observed in 11.1% and 23.0% of patients, respectively. Predictors for 2-year all-cause mortality differed by MR aetiology. While in primary MR cholestatic type II CHS was independently associated with 2-year mortality, ischaemic CHS type I was an independent mortality predictor in secondary MR patients. At follow-up, patients with MR reduction ≤2+ (obtained in 90.7% of patients) presented with improved parameters of hepatic function (median reduction of 0.2 mg/dl, 0.2 U/L and 21 U/L for bilirubin, alanine aminotransferase and gamma-glutamyl transferase, respectively, p < 0.01). CONCLUSIONS: The CHS is frequently observed in patients undergoing M-TEER and significantly impairs 2-year survival. Successful M-TEER may have beneficial effects on CHS.

RESUMO

OBJECTIVES: The aim of this study was to evaluate the prevalence and prognostic implications of cardiohepatic syndrome (CHS) in patients with tricuspid regurgitation (TR) treated with tricuspid transcatheter edge-to-edge valve repair (T-TEER). BACKGROUND: The role of CHS in patients undergoing T-TEER for severe TR has not been studied. METHODS: This study included patients who underwent T-TEER for TR between 2016 and 2020 at 2 high-volume academic centers. CHS was defined as elevation of at least 2 of 3 cholestatic hepatic enzymes. The impact of CHS on 1-year all-cause mortality and clinical outcomes after T-TEER was investigated. RESULTS: T-TEER reduced TR severity to ≤2+ in 257 of 305 included patients (86.2%). CHS was present in 45.2% of patients and was associated with a higher rate of mortality and of first hospitalization for heart failure (HHF) (CHS vs no CHS: estimated 1-year mortality, 34.0% vs 15.9% [P < 0.01]; HHF, 23.0% vs 12.2% [P = 0.01]). CHS was identified as an independent predictor of 1-year all-cause mortality (HR: 1.86; 95% CI: 1.10-3.14; P < 0.05). Irrespective of CHS, T-TEER improved New York Heart Association functional class and 6-minute walk distance in the majority of patients. In patients with impaired baseline hepatic function, laboratory liver parameters improved after T-TEER. CONCLUSIONS: CHS is a strong predictor of mortality and HHF after T-TEER and should be evaluated in the process of procedural decision making for T-TEER. Nevertheless, T-TEER is associated with relevant symptomatic alleviation irrespective of CHS.

RESUMO

BACKGROUND: To investigate the impact of left ventricular outflow tract (LVOT) calcification on the incidence of device failure and mortality in patients undergoing transcatheter aortic valve implantation (TAVI). METHODS: Of 690 consecutive patients undergoing transfemoral TAVI in our center from January 2013 to December 2015, 600 presented with non-severe (NSCALVOT) and 90 (13.0%) with severe (SCALVOT) LVOT calcification. Primary outcome of interest was device failure defined as a composite of procedural death, prosthesis dislocation, annulus rupture or significant para-valvular leakage (PVL). Secondary outcome of interest was 30-day and one-year all-cause mortality. RESULTS: Mean age of the population was 80.8 ±â€¯7.2 years, mean STS score was 5.7 ±â€¯4.6% and 50.6% of the patients were women. Patients with SCALVOT more frequently experienced device failure (10.0% vs. 3.8%, p = 0.009) and were at higher risk of 30 day (10.0% vs. 2.8%, p < 0.001) all cause mortality as compared to those with NSCALVOT. Furthermore, patients with SCALVOT were more frequently in need of post-dilation (15.6% vs. 8.5%, p = 0.032) and showed higher incidence of significant PVL (7.8% vs. 2.5%, p = 0.007). In multivariate analysis, SCALVOT (hazard ratio 2.87; 95% CI 1.20 to 6.34) and use of balloon-expandable prosthesis (hazard ratio 0.32; 95% CI 0.15 to 0.73) were identified as independent predictors of device failure. CONCLUSION: Presence of severe LVOT calcification in patients undergoing transfemoral TAVI is associated with a higher risk of device failure and short-term mortality.
