Abstract
AIMS Right ventricular dysfunction (RVD) on echocardiography has been shown to predict outcomes in patients undergoing transcatheter aortic valve replacement (TAVR). However, a comparison with the gold standard, RV ejection fraction (EF) on cardiovascular magnetic resonance (CMR), has never been performed. METHODS AND RESULTS Consecutive patients scheduled for TAVR underwent echocardiography and CMR. RV fractional area change (FAC), tricuspid annular plane systolic excursion, RV free-lateral-wall tissue Doppler (S'), and strain were assessed on echocardiography, and RVEF on CMR. Patients were prospectively followed. Adjusted regression analyses were used to report the strength of association per 1-SD decline for each RV function parameter with (i) N-terminal prohormone of brain natriuretic peptide (NT-proBNP) levels, (ii) prolonged in-hospital stay (>14 days), and (iii) a composite of heart failure hospitalization and death. Two hundred and four patients (80.9 ± 6.6 y/o; 51% female; EuroSCORE-II: 6.3 ± 5.1%) were included. At a cross-sectional level, all RV function parameters were associated with NT-proBNP levels, but only FAC and RVEF were significantly associated with a prolonged in-hospital stay [adjusted odds ratio 1.86, 95% confidence interval (CI) 1.07-3.21; P = 0.027 and 2.29, 95% CI 1.43-3.67; P = 0.001, respectively]. A total of 56 events occurred during follow-up (mean 13.7 ± 9.5 months). After adjustment for the EuroSCORE-II, only RVEF was significantly associated with the composite endpoint (adjusted hazard ratio 1.70, 95% CI 1.32-2.20; P < 0.001). CONCLUSION RVD as defined by echocardiography is associated with an advanced disease state but fails to predict outcomes after adjustment for pre-existing clinical risk factors in TAVR patients. In contrast, RVEF on CMR is independently associated with heart failure hospitalization and death.

Abstract
Background No randomized comparison of early (ie, ≤3 months) aortic valve replacement (AVR) versus conservative management or of transcatheter AVR (TAVR) versus surgical AVR has been conducted in patients with low‐flow, low‐gradient (LFLG) aortic stenosis (AS). Methods and Results A total of 481 consecutive patients (75±10 years; 71% men) with LFLG AS (aortic valve area ≤0.6 cm2/m2 and mean gradient <40 mm Hg), 72% with classic LFLG and 28% with paradoxical LFLG, were prospectively recruited in the multicenter TOPAS (True or Pseudo Severe Aortic Stenosis) study. True‐severe AS or pseudo‐severe AS was adjudicated by flow‐independent criteria. During follow‐up (median [IQR] 36 [11–60] months), 220 patients died. Using inverse probability of treatment weighting to address the bias of nonrandom treatment assignment, early AVR (n=272) was associated with a major overall survival benefit (hazard ratio [HR], 0.34 [95% CI, 0.24–0.50]; P<0.001). This benefit was observed in patients with true‐severe AS but also with pseudo‐severe AS (HR, 0.38 [95% CI, 0.18–0.81]; P=0.01), and in classic (HR, 0.33 [95% CI, 0.22–0.49]; P<0.001) and paradoxical LFLG AS (HR, 0.42 [95% CI, 0.20–0.92]; P=0.03). Compared with conservative management in the conventional multivariate model, trans femoral TAVR was associated with the best survival (HR, 0.23 [95% CI, 0.12–0.43]; P<0.001), followed by surgical AVR (HR, 0.36 [95% CI, 0.23–0.56]; P<0.001) and alternative‐access TAVR (HR, 0.51 [95% CI, 0.31–0.82]; P=0.007). In the inverse probability of treatment weighting model, trans femoral TAVR appeared to be superior to surgical AVR (HR [95% CI] 0.28 [0.11–0.72]; P=0.008) with regard to survival. Conclusions In this large prospective observational study of LFLG AS, early AVR appeared to confer a major survival benefit in both classic and paradoxical LFLG AS. This benefit seems to extend to the subgroup with pseudo‐severe AS. Our findings suggest that TAVR using femoral access might be the best strategy in these patients.

Abstract
The prevalence and significance of cardiac amyloidosis have been considerably underestimated in the past; however, the number of patients diagnosed with cardiac amyloidosis has increased significantly recently due to growing awareness of the disease, improved diagnostic capabilities and demographic trends. Specific therapies that improve patient prognosis have become available for certain types of cardiac amyloidosis. Thus, the earliest possible referral of patients with suspicion of cardiac amyloidosis to an experienced center is crucial to ensure rapid diagnosis, early initiation of treatment, and structured patient care. This requires intensive collaboration across several disciplines, and between resident physicians and specialized centers. The aim of this consensus statement is to provide guidance for the rapid and efficient diagnosis and treatment of light-chain amyloidosis and transthyretin amyloidosis, which are the most common forms of cardiac amyloidosis.

Abstract
Abstract
Background
Concomitant secondary atrioventricular regurgitation is frequent in patients with severe aortic stenosis scheduled fortranscatheter aortic valve replacement (TAVR). The future implications of leaving associated valve lesions untreated after TAVR remain unknown. Aim of the present study wasto characterize the evolution of concomitant secondary atrioventricular regurgitations and to evaluate their impact on long-term prognosis.
Methods
We prospectively enrolled 429 consecutive TAVR patients. All patients underwent comprehensive clinical, laboratory, and echocardiographic assessments prior to TAVR, at discharge, and yearly thereafter. All-cause mortality was chosen as primary study endpoint.
Results
At baseline, severe concomitant secondary mitral regurgitation (sMR) was present in 54 (13%) and severe concomitant secondary tricuspid regurgitation (sTR) in 75 patients (17%). After TAVR 59% of patients with severe sMR at baseline experienced sMR regression, whereas analogously sTR regressed in 43% of patients with severe sTR at baseline. Persistence of sTR and sMR were associated with excess mortality after adjustment for our bootstrap-selected confounder model with an adjusted HR of 2.44 (95% CI 1.15–5.20, P=0.021) for sMR and of 2.09 (95% CI 1.20–3.66, P=0.01) for sTR (Figure 1). Furthermore patients showing regression of atrioventricular regurgitation exhibited survival rates indistinguishable to those seen in patients without concomitant atrioventricular regurgitation (sMR: P=0.83; sTR: P=0.74)
Conclusion
Concomitant secondary atrioventricular regurgitation in patients with severe AS is a highly dynamic process with up to half of all patients showing regression of associated valvular regurgitation after TAVR and subsequent favorable post-interventional outcome. Persistent atrioventricular regurgitation is a major determinant of TAVR futility and proposes a window of early sequel intervention.

Abstract
Abstract
Background
Fluid overload, which may finally lead to cardiac decompensation, is a major threat in valvular heart disease (VHD) patients. In clinical practice, leg edema, pulmonary congestion, and rapid weight gain indicate fluid overload. However, these parameters lack both specificity and sensitivity. Bioelectrical impedance spectroscopy (BIS) is an easy, non-invasive and reliable way to determine the extent of fluid overload. BIS it already used in patients on chronic haemodialysis to guide therapy. Whether fluid status as measured by BIS is associated with outcome in VHD patients is unknown.
Methods
Stable patients with moderate or severe VHD as diagnosed by transthoracic echocardiography underwent fluid status assessment by BIS at baseline and were prospectively followed. The primary endpoint was a composition of heart failure hospitalisation and cardiovascular death. Patients with overt cardiac decompensation or on intra-venous diuretic therapy were excluded from this study. Kaplan-Meier estimates and multivariable Cox-regression analysis were used to identify sex-specific factors associated with outcome. This study was registered at clinicaltrials.gov (NCT03372512).
Results
336 patients (51.8% female, 76±13 years) were included in the study. 26.2% (3.5% moderate, 22.7% severe) suffered from aortic stenosis, 50.9% from mitral regurgitation (16.1% moderate, 34.2%severe) and 11.8% (6.2% moderate, 5.6% severe) from aortic regurgitation. A total of 68.5% of the patients additionally presented with tricuspid regurgitation.
Mean overhydration was +0.6l with no significant differences between men and women (p=0.076). We did not observe sex-specific differences in baseline characteristics with the exception of higher left-ventricular ejection fraction (p=0.007) as well as better renal function (p=0.003) in women compared to men.
During a follow-up of 433±364 days, a total of 153 events (45.7%) occurred. 102 patients (30.4%) underwent valve intervention, which was not considered as an event, and were censored from the analysis.
Sex-specific stratification of patients based on OH tertiles revealed that overhydration was associated with significantly higher event-rates in men (log-rank p=0.002, see Figure 1), but not in women (p=0.127, see Figure 2). Similarly, in the multivariate cox-regression, OH was significantly associated with outcome only in men (p=0.009) after adjustment for cardiac size and function, NT-proBNP, diabetes, coronary artery disease, NYHA functional class, renal function, and history of cardiac decompensation. In female patients, only NT-proBNP (p=0.001) was significantly associated with outcome whereas OH was not (p=0.849).
Conclusions
Fluid status, as determined with BIS, is significantly associated with outcome in male but not in female patients with VHD. Sex-specific approaches for risk assessment and fluid management should be further examined.

Abstract
Abstract
Background
Right ventricular (RV) function is strongly associated with outcome in heart failure. Whether it also adds important prognostic information in patients undergoing transcatheter aortic valve implantation (TAVI) is unknown.
Methods
We consecutively enrolled patients with severe aortic stenosis (AS) scheduled for TAVI and preprocedural cardiac magnetic resonance (CMR) imaging. Kaplan-Meier estimates and multivariate Cox regression analyses were used to identify factors associated with outcome. A composite of heart failure hospitalization and/or cardiovascular death was selected as primary study endpoint.
Results
423 consecutive patients (80.7±7.3 years; 48% female) were prospectively included, 201 (48%) underwent CMR imaging. 55 (27%) patients presented with RV systolic dysfunction (RVSD) defined by RV ejection fraction (RVEF) <45%. RVSD was associated with male sex (69 vs. 40%; p<0.001), New York Heart Association (NYHA) functional status (NYHA ≥ III: 89 vs. 57%; p<0.001), NT-proBNP serum levels (9365 vs. 2715 pg/mL; p<0.001), and history of atrial fibrillation (AF: 51 vs. 30%; p=0.005). On CMR, RVSD was associated with left ventricular (LV) volumes (end-diastolic: 187 vs. 137 mL, end-systolic: 119 vs. 53 mL; p<0.001) and EF (39 vs. 64%; p<0.001).
A total of 51 events (37 deaths, 14 hospitalizations for heart failure) occurred during follow-up (9.8±9 months). While LVSD (LVEF <50%) was not significantly associated with outcome (HR 0.83, 95% CI: 0.33 – 2.11; p=0.694), RVSD showed a strong and independent association with event-free survival by multivariate Cox regression analysis (HR 2.47, 95% CI: 1.07–5.73; p=0.035), which was adjusted for all relevant CMR parameters (LV volumes and EF), cardiovascular risk factors (sex, NYHA, AF, diabetes mellitus type II, use of diuretics), and routine biomarkers (NT-proBNP, creatinine).
Conclusions
RVSD rather than LVSD, as determined on CMR, is an important predictor of outcome in patients undergoing TAVI. RV function might thus add useful prognostic information on top of established risk factors.

Abstract
Abstract
Background
Transcatheter aortic valve implantation (TAVI) is increasingly used for the treatment of severe symptomatic aortic stenosis (AS), also in low-risk patients. Periprocedural embolic stroke is rare, but potentially associated with considerable morbidity and mortality. Thus, there is great interest in preventing any cerebral embolic event. At present, only one cerebral embolic protection systems (CPS) is commercially available and little is known about its efficacy in preventing stroke during TAVI. The Sentinel CPS is a FDA-approved system consisting of two inter-connected filters that are placed in the brachiocephalic trunk and the left carotid artery via the right radial artery.
Material and methods
Consecutive patients undergoing TAVI between 11/2018 and 11/2019 were enrolled. Consecutive patients treated by one operator received the Sentinel device, if anatomically possible. Periprocedural stroke rate, as defined by VARC2-criteria, and mortality up to 7 days after procedure was assessed. Descriptive statistics was performed to identify baseline variables associated with elevated risk of stroke and Cox-regression analysis was used to investigate its influence on outcome.
Results
268 patients (47.4% female, 81±7 years) were included. In 74 patients (27.6%), a Sentinel CPS was used, in 63 (23.5%) it was positioned correctly in the brachiocephalic trunk and left carotid artery. Only these patients were considered Sentinel-protected. Patients with and without Sentinel presented with similar baseline characteristics with regard to age (no CPS vs CPS; 80.3 vs 81.5 years; p=0.233), sex (female 47.3% vs 47.7%; p=0.967), previous stroke (6.9% vs 3.2%; p=0.373), peripheral artery disease (9.8% vs 4.8%; p=0.305), coronary artery disease (63.1% vs 57.1%; p=0.370), and kidney function (GFR 52 vs 56 ml/min/m2; p=0.283). The EuroScore II (6% vs 6%; p=0.937), periprocedural predilation (48.3% vs 47.6; p=0.925), postdilation (29.3% vs 31.7%; p=0.707) and procedure time (59min vs 66min; p=0.152) were not different. In total, 15 strokes (5.6%) occurred, of which 9 (3.3%) were disabling strokes as defined by the VARC2-criteria. In Sentinel-protected patients undergoing TAVI, no periprocedural stroke was observed (no CPS 7.3% vs 0.0%; p=0.026).
Conclusion
Our results suggest that Sentinel CPS significantly reduces periprocedural stroke rates in patients undergoing TAVI compared to patients without CPS. However, the study population is small and randomized trials are still needed.

Abstract
Abstract
Background
Implantable interatrial shunt devices improve pulmonary vascular function in patients with heart failure by transferring richly oxygenated blood to the right heart. Whether iatrogenic atrial septum defects (iASDs) after percutaneous edge-to-edge mitral valve repair (pMVR) are also associated with beneficial hemodynamic effects has not been investigated.
Methods
We consecutively enrolled patients with relevant functional (FMR) and degenerative mitral regurgitation (DMR) scheduled for pMVR. Invasive hemodynamic assessments were performed prior to and immediately after the procedure.
Results
97 consecutive patients (75.4±9.1 years; 58% female) were prospectively included, 65 (66%) presented with relevant FMR. At baseline when compared to the DMR group, FMR was associated with worse left ventricular (LV) function (LV ejection fraction: 39 vs. 49%; p=0.001), higher NT-proBNP levels (7404 vs. 5214 pg/mL; p=0.023), worse renal function (serum creatinine: 1.7 vs. 1.3 mg/dL; p=0.019), and higher usage of spironolactone (68 vs. 42%; p=0.018) and sacubitril/valsartan (33 vs. 0%; p<0.001).
Following pMVR, cardiac output (CO) and systemic blood flow (Qs) increased significantly (CO: 4.6 to 5.5 L/min; p<0.001; Qs: 4.9 to 5.8 L/min; p=0.002), with more pronounced changes in the FMR subgroup (ΔCO: 1.0 vs. 0.6 L/min; Figure 1A; ΔQs: 1.2 vs. 0.1 L/min), when compared to DMR. Pulmonary blood flow (Qp) increased by 26% (4.3 to 5.4 L/min; p=0.008), accompanied by a raise in pulmonary artery (PA) oxygen (O2) saturation from 73 to 77% (p<0.001). Arterial O2 saturation levels remained unchanged (98.3 to 98.7%; p=0.165), confirming no significant changes in systemic oxygenation. These changes were associated with a slight decline in pulmonary vascular resistance (PVR: 250 to 225 dynes*sec/cm5; p=0.369, Figure 1B), and a tendency towards improvement of pulmonary compliance (PAC: 3.6 to 4.0 mL/mmHg; p=0.414).
Conclusions
Invasively measured CO, Qs, Qp, and mixed-venous PA O2 saturation increased immediately after pMVR, alongside with potentially beneficial effects on pulmonary vasculature with marked improvements in PVR and PAC. These changes were more pronounced in the FMR subgroup. Further studies are required to assess long-term hemodynamic effects and underlying mechanisms of persistent iASDs on pulmonary vascular function.

Abstract
BACKGROUND The pulmonary artery (PA) to ascending aorta diameter ratio (PA:A) has been evaluated in numerous studies analyzing cardiac magnetic resonance (CMR) and computed tomography (CT) data. Previously, no transthoracic echocardiography (TTE) cutoffs have been published. We sought to evaluate (1) the feasibility to image the pulmonary trunk in a prospective cohort, and (2) the ability of PA:A derived by TTE to predict pulmonary hypertension (PH). METHODS We performed a post-hoc analysis of a prospectively recruited consecutive cohort of patients referred to our tertiary center cardiology department due to suspicion for PH. Invasive hemodynamic assessment and quasi-simultaneous TTE was performed in all participants. RESULTS A total of 84 patients were included in the analysis, median age was 70.5 years (IQR 58-75), 46 (55%) were female. The PA was significantly wider in the PH group (28mm vs. 22.5mm, p<0.001) with a resulting median PA:A of 0.84 vs. 0.66 (p<0.001). Both PA diameter (r = 0.524 and r = 0.44, both p<0.001) and PA:A (r = 0.652 and 0.697, both p<0.001) significantly correlated with mPAP and with PVR, respectively. Area under the curve for the detection of PH was 0.853 (95%CI 0.739-0.967, p<0.001). CONCLUSION The PA can be visualized in almost all echocardiographic exams, especially when it is dilated. A view showing the pulmonary trunk should be included in every routine TTE. An increased PA:A should raise suspicion for PH and prompt further evaluation and follow-up examinations of these patients.

Abstract
AIMS Concomitant secondary atrioventricular regurgitation is frequent in patients with severe aortic stenosis scheduled for transcatheter aortic valve replacement (TAVR). The future implications of leaving associated valve lesions untreated after TAVR remain unknown. Aim of the present study was to characterize the evolution of concomitant secondary atrioventricular regurgitations and to evaluate their impact on long-term prognosis. METHODS AND RESULTS We prospectively enrolled 429 consecutive TAVR patients. All patients underwent comprehensive clinical, laboratory, and echocardiographic assessments prior to TAVR, at discharge, and yearly thereafter. All-cause mortality was chosen as primary study endpoint. At baseline, severe concomitant secondary mitral regurgitation (sMR) was present in 54 (13%) and severe concomitant secondary tricuspid regurgitation (sTR) in 75 patients (17%). After TAVR 59% of patients with severe sMR at baseline experienced sMR regression, whereas analogously sTR regressed in 43% of patients with severe sTR. Persistence of sTR and sMR were associated with excess mortality after adjustment for our bootstrap-selected confounder model with an adjusted HR of 2.44 (95% CI 1.15-5.20, P = 0.021) for sMR and of 2.09 (95% CI 1.20-3.66, P = 0.01) for sTR. Patients showing regression of atrioventricular regurgitation exhibited survival rates indistinguishable to those seen in patients without concomitant atrioventricular regurgitation (sMR: P = 0.83; sTR: P = 0.74). CONCLUSION Concomitant secondary atrioventricular regurgitation in patients with severe AS is a highly dynamic process with up to half of all patients showing regression of associated valvular regurgitation after TAVR and subsequent favourable post-interventional outcome. Persistent atrioventricular regurgitation is a major determinant of unfavourable outcome after TAVR and proposes a window of early sequel intervention.

Abstract
Background In heart failure with preserved ejection fraction (HFpEF), echocardiographic studies suggest that global longitudinal strain (GLS) has an impact on survival. Feature-tracking cardiovascular MRI also allows for strain analysis; however, to the knowledge of the authors, little is known about its prognostic value and whether it reflects severity of diffuse fibrosis, as assessed by cardiovascular MRI T1 mapping. Purpose To investigate the association between myocardial strain at cardiovascular MRI with extracellular volume by T1 mapping and outcome in participants with HFpEF. Materials and Methods In this secondary analysis of a prospective study (NCT03405987), consecutive participants with HFpEF underwent cardiovascular MRI between July 2012 and March 2018, including T1 mapping and three-dimensional strain analysis. Extracellular volume and strain results were assessed to determine if there was a correlation between these two factors. Cox regression was performed to determine the prognostic relevance of MRI-derived myocardial strain for a combined end point (events) of heart failure hospitalizations and cardiovascular death. Results In total, 206 consecutive participants with HFpEF (mean age, 71 years ± 8 [standard deviation]; 69% women) were included. Median myocardial global longitudinal strain (GLS) at MRI was -8.5% and showed low correlation with extracellular volume (r = 0.28; P = .003). A total of 109 events (53%) were recorded during a follow-up of 38 months ± 29. Participants with a GLS above the median had higher event rates (log-rank test, P < .001). By multivariable Cox regression analysis, GLS remained independently associated with outcome (hazard ratio, 1.06 per 1% strain increase; 95% confidence interval: 1.01, 1.11; P = .03) when corrected for risk factors including age, diabetes, renal function, N-terminal pro-b-type natriuretic peptide serum concentration, and right ventricular size and function. Conclusion In participants with heart failure with preserved ejection fraction, global longitudinal strain at cardiovascular MRI was correlated with extracellular volume by T1 mapping and was associated with cardiovascular events. © RSNA, 2020 Online supplemental material is available for this article.

Abstract
This study sought to characterize cardiac amyloidosis (CA) patients with respect to hemodynamic parameters and asses their prognostic impact in different CA cohorts. Intracardiac and pulmonary arterial pressures (PAPs) are among the strongest predictors of outcomes in patients with heart failure (HF). Despite that, the hemodynamic profiles of patients with CA and their relation to prognosis have rarely been investigated. Invasive hemodynamic, clinical, and laboratory assessment, as well as cardiac magnetic resonance imaging were performed in our CA cohort. A total of 61 patients, 35 (57.4%) with wild-type transthyretin amyloidosis (ATTRwt) and 26 (42.6%) with light-chain amyloidosis (AL) were enrolled. ATTRwt patients had lower N-terminal prohormone of brain natriuretic peptide values and were less frequently in New York Heart Association class ≥ III. Intracardiac and PAPs were elevated, but hemodynamic parameters did not differ between CA groups. Whereas in ATTRwt, the median mean PAP (hazard ratio (HR): 1.130, p = 0.040) and pulmonary vascular resistance (HR: 1.010, p = 0.046) were independent predictors of outcome, no hemodynamic parameter was associated with outcome in the AL group. Cardiac ATTRwt and AL patients feature elevated intracardiac and PAPs and show similar hemodynamic profiles. However, hemodynamic parameters are of greater prognostic relevance in ATTRwt, potentially providing a new therapeutic target.

Abstract
Tricuspid regurgitation in patients with left ventricular assist device (LVAD) has a significant impact on prognosis and quality of life, and its effects on liver and renal function could negatively impact planned heart transplantation. The aim of the present case is to report the feasibility and the clinical impact of tricuspid transcatheter edge‐to‐edge repair in LVAD patients as adjunctive bridge to transplantation strategy. A 59‐year‐old female patient previously treated with LVAD implantation (HeartMate III) and tricuspid valve repair with 32 mm rigid ring (Medtronic Contour 3D) as bridge to transplantation developed recurrence of significant tricuspid regurgitation with right ventricular decompensation needing inotropic support. Preoperative echo showed torrential tricuspid valve regurgitation Effective regurgitant orifice area(EROA 1.4 cm2) with suspicious of partial detachment of the prosthetic ring. The patient was successfully treated with transcatheter edge‐to‐edge repair with the MitraClip XTR device. Tricuspid regurgitation was reduced by 50% (postoperative EROA 0.7 cm2). She remained stable under continuous inotropic support with no other episodes of right ventricular decompensation and was successfully transplanted 30 days after the clipping procedure. Transcatheter treatment of tricuspid regurgitation in a patient with LVAD was an effective strategy to gain time and bridge the patient to heart transplantation.

Abstract
Aims Concomitant cardiac amyloidosis (CA) in severe aortic stenosis (AS) is difficult to recognize, since both conditions are associated with concentric left ventricular thickening. We aimed to assess type, frequency, screening parameters, and prognostic implications of CA in AS. Methods and results A total of 191 consecutive AS patients (81.2 ± 7.4 years; 50.3% female) scheduled for transcatheter aortic valve replacement (TAVR) were prospectively enrolled. Overall, 81.7% underwent complete assessment including echocardiography with strain analysis, electrocardiography (ECG), cardiac magnetic resonance imaging (CMR), 99mTc‐DPD scintigraphy, serum and urine free light chain measurement, and myocardial biopsy in immunoglobulin light chain (AL)‐CA. Voltage/mass ratio (VMR; Sokolow–Lyon index on ECG/left ventricular mass index) and stroke volume index (SVi) were tested as screening parameters. Receiver operating characteristic curve, binary logistic regression, and Kaplan–Meier curve analyses were performed. CA was found in 8.4% of patients (n = 16); 15 had transthyretin (TTR)‐CA and one AL‐CA. While global longitudinal strain by echo did not reliably differentiate AS from CA‐AS [area under the curve (AUC) 0.643], VMR as well as SVi showed good discriminative power (AUC 0.770 and 0.773, respectively), which was comparable to extracellular volume by CMR (AUC 0.756). Also, VMR and SVi were independently associated with CA by multivariate logistic regression analysis (P = 0.016 and P = 0.027, respectively). CA did not significantly affect survival 15.3 ± 7.9 months after TAVR (P = 0.972). Conclusion Both TTR‐ and AL‐CA can accompany severe AS. Parameters solely based on ECG and echocardiography allow for the identification of the majority of CA‐AS. In the present cohort, CA did not significantly worsen prognosis 15.3 months after TAVR.

Eur J Clin Invest 2020; 50:e13184.

Abstract
BACKGROUND Atrial fibrillation (AF) is a frequent finding in HFpEF. However, its association with invasive haemodynamics, imaging parameters and outcome in HFpEF is not well established. Furthermore, the relevance of AF subtype with regard to outcome is unclear. This study sought to investigate the prognostic impact of paroxysmal and persistent AF in a well-defined heart failure with preserved ejection fraction (HFpEF) population. MATERIALS AND METHODS Between 2010 and 2016, 254 HFpEF patients were prospectively enrolled. All patients underwent echocardiography as well as left and right heart catheterization. Patients without contraindications underwent CMR including T1 mapping. Follow-up and outcome data were collected. Patients with significant coronary artery disease were excluded. RESULTS A total of 153 patients (60%) suffered from AF, 119 (47%) had persistent and 34 (13%) had paroxysmal AF. By multiple logistic regression analysis, persistent AF was independently associated with NT-proBNP (P = .003), NYHA functional class (P = .040), left and right atrial size (P = .022 and <.001, respectively), cardiac output (P = .002) and COPD (P = .034). After a median follow-up of 23 months (interquartile range 5-48), 92 patients (36%) reached the primary end point defined as hospitalization for heart failure or cardiovascular death. By multivariate Cox regression analysis, only persistent AF (P = .005) and six-minute walk distance (P = .011) were independently associated with the primary end point. CONCLUSIONS Sixty percent of our HFpEF patients suffered from AF. Persistent but not paroxysmal AF was strongly associated with event-free survival and was independently related to NYHA functional class, serum NT-proBNP, atrial size, cardiac ouput and presence of COPD.
