RESUMEN
BACKGROUND: Right ventricular (RV) dysfunction in patients undergoing transcatheter aortic valve implantation (TAVI) for aortic stenosis (AS) has long been disregarded. We aimed to assess the predictive value of RV to pulmonary artery coupling (RV/PAc), defined as tricuspid annular plane systolic excursion to systolic pulmonary artery pressure, on mortality in different flow types of AS after TAVI. METHODS: All patients undergoing TAVI for AS at our centre between 2018 and 2020 were assessed; 862 patients were analysed. The cohort was dichotomized using a ROC analysis (cut-off 0.512 mm/mmHg), into 429 patients with preserved and 433 patients with reduced RV/PAc. RESULTS: Reduced RV/PAc was associated with male sex and a higher rate of comorbidities. Short-term VARC-3 endpoints and NYHA classes at follow-up were comparable. Reduced RV/PAc was associated with higher 2-year all-cause mortality (35.0% [30.3-39.3%] vs. 15.4% [11.9-18.7%], hazard ratio 2.5 [1.9-3.4], p < 0.001). Cardiovascular mortality was almost tripled. Results were consistent after statistical adjustment and in a multivariate model. Sub-analyses of AS flow types revealed lower RV/PAc in classical and paradoxical low-flow low-gradient AS, with the majority having reduced RV/PAc (74% and 59%). RV/PAc retained its predictive value in these subgroups. CONCLUSIONS: RV dysfunction defined by low RV/PAc is a strong mortality predictor after TAVI independent of flow group. It should be incorporated in future TAVI risk assessment.
RESUMEN
BACKGROUND: Knowledge about atrial functional tricuspid regurgitation (afTR) in transcatheter aortic valve replacement (TAVR) patients is scarce. OBJECTIVES: The aim of the study was to analyze the association between the entity and the development of tricuspid regurgitation (TR) in patients undergoing TAVR for aortic stenosis and concomitant TR. METHODS: We analyzed patients undergoing TAVR for severe aortic stenosis from January 2013 to December 2020 and concomitant at least moderate TR at baseline. afTR was defined as enlargement of the right atrium in relation to the right ventricle. TR development after TAVR and 3-year all-cause mortality were evaluated. RESULTS: Out of 3,474 TAVR patients, we identified 420 patients with concomitant at least moderate TR. A total of 363 patients were included in the study, with 178 patients stratified in the afTR and 185 in the non-afTR group based on a receiver-operating characteristic curve cutoff of 1.132 of the right atrial/right ventricular area ratio. TR improvement after TAVR was observed in significantly less patients with afTR compared with non-afTR (31.1% vs 60.6%; P < 0.001). Multivariate regression analysis confirmed afTR as independent predictor for TR persistence (adjusted OR: 2.80; 95% CI: 1.66-4.76; P < 0.001). Moreover, afTR was associated with aggravation of TR after TAVR (17.0% vs 6.8%; P = 0.013). Three-year all-cause mortality was significantly higher in patients with persistence compared with patients with improvement of TR (P < 0.001). CONCLUSIONS: In TAVR patients, afTR is an independent predictor for TR persistence. Moreover, TR persistence is associated with increased 3-year all-cause mortality.

BACKGROUND: The efficacy and safety of saline versus balanced crystalloid solutions in ICU-patients remains complicated by exceptionally heterogenous study population in past comparative studies. This study sought to compare saline and balanced crystalloids for fluid resuscitation in patients with cardiogenic shock with or without out-of-hospital cardiac arrest (OHCA). METHODS: We retrospectively analyzed 1032 propensity score matched patients with cardiogenic shock from the Munich University Hospital from 2010 to 2022. In 2018, default resuscitation fluid was changed from 0.9% saline to balanced crystalloids. The primary endpoint was defined as 30-day mortality rate. RESULTS: Patients in the saline group (n = 516) had a similar 30-day mortality rate as patients treated with balanced crystalloids (n = 516) (43.1% vs. 43.0%, p = 0.833), but a higher incidence of new onset renal replacement therapy (30.2% vs 22.7%, p = 0.007) and significantly higher doses of catecholamines. However, OHCA-patients with a lactate level higher than 7.4 mmol/L had a significantly lower 30-day mortality rate when treated with saline (58.6% vs. 79.3%, p = 0.013). In addition, use of balanced crystalloids was independently associated with a higher mortality in the multivariate cox regression analysis after OHCA (hazard ratio 1.43, confidence interval: 1.05-1.96, p = 0.024). CONCLUSIONS: In patients with cardiogenic shock, use of balanced crystalloids was associated with a similar all-cause mortality at 30 days but a lower rate of new onset of renal replacement therapy. In the subgroup of patients after OHCA with severe shock, use of balanced crystalloids was associated with a higher mortality than saline.

RESUMEN
BACKGROUND: Cardiohepatic syndrome (CHS) has been identified as an important but underrecognized survival predictor in multiple cardiovascular disease entities. The objectives of this study were to evaluate the prevalence and prognostic value of CHS in patients undergoing TAVR for severe aortic stenosis (AS). METHODS: The study included patients with available laboratory parameters of hepatic function who underwent TAVR from July 2013 until December 2019 at our center. CHS was defined as an elevation of at least two of three laboratory cholestasis parameters above the upper limit of normal (bilirubin, alkaline phosphatase, and gamma glutamyl transferase). Study endpoints were three-year survival, technical and device failure (VARC 3), as well as New York Heart Association (NYHA) functional class at follow-up. RESULTS: Among a total of 953 analyzed patients (47.6% females, median age 80.0 [76.0-85.0] years) CHS was present in 212 patients (22.4%). In patients with vs. without CHS, rates of technical (6.1% vs. 8.4%, p = 0.29) and device failure (18.9% vs. 17.3%, p = 0.59) were comparable. NYHA functional class at baseline and follow-up was more severe in patients with CHS. Nevertheless, heart failure symptoms improved from baseline to follow-up irrespective of hepatic function. Three-year survival rates were significantly lower in patients with CHS (49.4 vs. 65.4%, p < 0.001). The predictive value of CHS persisted after adjustment in a multivariable analysis (hazard ratio 1.58, p < 0.01). CONCLUSION: In patients undergoing TAVR, CHS is prevalent in 22% of patients and is associated with increased postinterventional mortality. Thus, CHS should be included in the decision-making process within the TAVR heart team. Cardiohepatic syndrome (CHS) as defined by an elevation of at least two of three laboratory cholestasis parameters above the upper limit of normal was prevalent in 22% of patients undergoing TAVR for severe AS. The presence of CHS was associated with more severe heart failure symptoms and worse three-year survival.

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.

AIM: The aim of this study was to analyse the predictive value of CTA-determined tricuspid annular dilatation (TAD) on the persistence of tricuspid regurgitation (TR) in patients undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS) and concomitant at least moderate TR. METHODS AND RESULTS: 288 consecutive patients treated with TAVR due to severe AS and concomitant at least moderate TR at baseline were included in the analysis. As cutoff for TAD, the median value of the CTA-determined, to the body surface area-normalized tricuspid annulus diameter (25.2 mm/m2) was used. TAD had no impact on procedural characteristics or outcomes, including procedural death and technical or device failure according to the Valve Academic Research Consortium 3 criteria. However, the primary outcome of the study-TR persistence after TAVR was significantly more frequent in patients with compared to patients without TAD (odds ratio 2.60, 95% confidence interval 1.33-5.16, p < 0.01). Multivariable logistic regression analysis, adjusting for clinical and echocardiographic baseline characteristics, which are known to influence aetiology or severity of TR, confirmed TAD as an independent predictor of TR persistence after TAVR (adjusted odds ratio 2.30, 95% confidence interval 1.20-4.46, p = 0.01). Moreover, 2 year all-cause mortality was significantly higher in patients with persistence or without change of TR compared to patients with TR improvement (log-rank p < 0.01). CONCLUSION: In patients undergoing TAVR for severe AS and concomitant at least moderate TR at baseline, TAD is a predictor of TR persistence, which is associated with increased 2-year all-cause mortality.

BACKGROUND: Large-bore arteriotomy for transcatheter aortic valve implantation (TAVI) requires percutaneous vascular closure devices, but real-world data comparing different closure strategies are limited. AIMS: We sought to compare a dual ProGlide strategy vs a combination of one ProGlide and one FemoSeal for vascular closure after TAVI. METHODS: We retrospectively analysed 874 propensity score-matched patients undergoing TAVI at the Munich University Hospital from August 2018 to October 2020. From August 2018 to August 2019, a dual ProGlide strategy was used for vascular closure. From October 2019 to October 2020, a combination of one ProGlide and one FemoSeal was used. The primary endpoint was defined as access-related major vascular complications or bleeding ≥Type 2 according to Valve Academic Research Consortium 3 criteria. RESULTS: Patients in the dual ProGlide group (n=437) had a higher incidence of the primary endpoint than patients treated with one ProGlide and one FemoSeal (n=437; 11.4% vs 3.0%; p<0.001). Furthermore, they had a higher rate of closure device failure (2.7% vs 0.9%; p=0.044) and more often required unplanned surgery or endovascular treatment (3.9% vs 0.9%; p=0.004). The incidence of death did not differ significantly between groups (3.4% vs 1.6%; p=0.08). CONCLUSIONS: A combined ProGlide and FemoSeal strategy might have the potential to reduce access-related vascular complications following TAVI.

BACKGROUND: Transcatheter treatment techniques for tricuspid regurgitation (TR) have evolved in recent years, with leaflet repair being the most commonly used, but thus far evidence on the PASCAL and PASCAL Ace system is based mainly on compassionate use data. OBJECTIVES: This is the first report on commercial use in a multicenter study with a large patient cohort investigating the safety and efficacy of the PASCAL and PASCAL Ace system in the treatment of TR. METHODS: In a retrospective, multicenter, observational setting, data from all consecutive patients undergoing leaflet repair for TR at 8 centers was collected, including a centralized analysis of echocardiographic data. RESULTS: A total of 235 high-risk patients (mean age 78 ± 8 years, 49% women, mean Society of Thoracic Surgeons Predicted Risk of Mortality score 8.6% ± 6.8%) were included. TR was functional in 87% of patients and graded severe or higher in 91%. TR was successfully reduced to moderate or less in 78% of patients (P < 0.001). Procedural success was 78% (n = 153). At the latest available follow-up (median 173 days), TR reduction was sustained (78% with TR moderate or less; P < 0.001), and echocardiography showed indications of right ventricular remodeling (mean right ventricular end-diastolic diameter 56 ± 9 mm vs 53 ± 9 mm; P < 0.001). Patients' symptoms diminished significantly (63% were in New York Heart Association functional class I or II at follow-up; P < 0.001). In a device-specific analysis, the PASCAL and PASCAL Ace showed no difference in TR reduction (postprocedural TR moderate or less in 77% vs 78%; P = 0.82). CONCLUSIONS: In early clinical experience, the PASCAL (Ace) leaflet repair system has high technical and procedural success rates with efficient TR reduction and significant clinical and echocardiographic improvement at follow-up.

Despite the rapid increase in experience and technological improvement, the incidence of conduction disturbances in patients undergoing transcatheter aortic valve replacement (TAVR) with the self-expandable CoreValve Evolut valve remains high. Recently, a cusp-overlap view (COP) implantation technique has been proposed for TAVR with self-expandable valves offering an improved visualization during valve expansion compared to the three-cusp view (TCV). This study aims to systematically analyze procedural outcomes of TAVR patients treated with the CoreValve Evolut valve using a COP compared to TCV in a high-volume center. The primary endpoint was technical success according the 2021 VARC-3 criteria. A total of 122 consecutive patients (61 pts. TCV: April 2019 to November 2020; 61 pts. COP: December 2020 to October 2021) that underwent TAVR with the CoreValve Evolut prosthesis were included in this analysis. Although there was no difference in the primary endpoint technical success between TCV and COP patients (93.4% vs. 90.2%, OR 0.65, 95% CI 0.16, 2.4, p = 0.51), we observed a significantly lower risk for permanent pacemaker implantation (PPI) among COP patients (TCV: 27.9% vs. COP: 13.1%, OR 0.39, 95% CI 0.15, 0.97, p = 0.047). Implantation of the CoreValve Evolut prosthesis using the COP might help to reduce the rate of PPI following TAVR.
RESUMEN
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.

BACKGROUND: The impact of postero-anterior and medio-lateral mitral valve (MV) tethering patterns on outcomes in patients undergoing transcatheter edge-to-edge repair (M-TEER) for secondary mitral regurgitation (SMR) is unknown. METHODS: The ratio of the posterior to anterior MV leaflet angle (PLA/ALA) in MV segment 2 was defined as postero-anterior tethering asymmetry. Medio-lateral tethering asymmetry was assessed as the ratio of the medial (segment 3) to lateral (segment 1) MV tenting area. We used receiver-operating characteristics and a Cox regression model to identify cut-off values of asymmetric anteroposterior and medio-lateral tethering for prediction of 2 year all-cause mortality after TMVR. RESULTS: Among 178 SMR patients, postero-anterior tethering was asymmetric in 67 patients (37.9%, PLA/ALA ratio > 1.54). Asymmetric medio-lateral tethering (tenting area ratio > 1.49) was observed in 49 patients (27.5%). M-TEER reduced MR to ≤ 2 + in 92.1% of patients; MR reduction was less effective in the presence of asymmetric postero-anterior tethering (p = 0.02). A multivariable Cox regression model identified both types of asymmetric MV tethering to be associated with increased all-cause 2-year mortality (postero-anterior tethering asymmetry: HR = 2.77, CI 1.43-5.38; medio-lateral tethering asymmetry: HR = 2.90, CI 1.54-5.45; p < 0.01). CONCLUSIONS: Asymmetric postero-anterior and medio-lateral MV tethering patterns are associated with increased 2-year mortality in patients undergoing M-TEER for SMR. A detailed echocardiographic analysis of MV anatomy may help to identify patients who profit most from M-TEER.
