Profiles of Geriatric Syndromes and Resources in Older Patients with Atrial Fibrillation.

Objective: Older patients with nonvalvular atrial fibrillation (AF) are at high risk for frailty and geriatric syndromes (GSs), which modulate their individual prognosis and are therefore relevant for further management. Because few studies have evaluated the geriatric profile of older AF patients, this secondary analysis aims to further characterize the patterns of GSs and geriatric resources (GRs) in AF patients and their association with anticoagulation use. Methods: Data from 362 hospitalized patients aged 65 years and older with AF (n = 181, 77.8 ± 5.8 years, 38% female) and without AF (non-AF [NAF]; n = 181, 77.5 ± 5.9 years, 40% female) admitted to an internal medicine and nephrology ward of a large university hospital in Germany were included. All patients underwent usual care plus a comprehensive geriatric assessment (CGA) including calculation of the Multidimensional Prognostic Index (MPI) and collection of 17 GSs and 10 GRs. Patients were followed up by telephone 6 and 12 months after discharge to collect data on their health status. Results: The mean MPI score of 0.47 indicated an average risk of poor outcome, and patients with AF had a significantly higher MPI than those without AF (p = 0.040). After adjustment for chronological age, biological sex, Cumulative Illness Rating Scale (CIRS) for relevant chronic diagnoses and MPI as a proxy for biological age, AF patients had significantly more mnestic resources (63.5% vs. 33.1%, p < 0.001), a tendency for less age-appropriate living conditions (56.4% vs. 72.9%, p = 0.051) and more sensory impairment (78.5% vs. 52.5%, p < 0.001) than NAF patients. They also had a higher number of GSs (p = 0.046). AF patients on oral anticoagulants (OACs, n = 91) had less age-appropriate living conditions (48.4% vs. 64.4%, p < 0.05) and mnestic resources (36.3% vs. 54.4%, p < 0.01), but more emotional resources (80.2% vs. 65.6%, p < 0.05) and chronic pain (56% vs. 40%, p < 0.05) than patients without OACs (n = 90). Overall, mortality at 1 year was increased in patients with a higher MPI (p < 0.009, adjusted for age, sex and CIRS), with a diagnosis of AF (p = 0.007, adjusted for age, sex, CIRS and MPI), with of male sex (p = 0.008, adjusted for age, CIRS and MPI) and those with AF and treated with hemodialysis (p = 0.022, compared to AF patients without dialysis treatment). Conclusions: Patients with AF and patients with AF and OACs show differences in their multidimensional frailty degree as well as GR and GS profiles compared to patients without AF or with AF not treated with OACs. Mortality after 1 year is increased in AF patients with a higher MPI and dialysis, independently from OAC use and overall burden of chronic disease as assessed per CIRS. GRs and GSs, especially age-appropriate living conditions, emotional resources, sensory impairment and chronic pain, can be considered as factors that may modify the individual impact of frailty, underscoring the relevance of these parameters in the management of older patients.

Early Outcomes of Two Large Mitral Valve Transcatheter Edge-to-Edge Repair Devices-A Propensity Score Matched Multicenter Comparison.

Background/Objectives: Previous trials reported comparable results with PASCAL and earlier MitraClip generations. Limited comparative data exist for more contemporary MitraClip generations, particularly the large MitraClip XT(R/W). We aimed to evaluate acute and 30-day outcomes in patients undergoing mitral valve transcatheter edge-to-edge repair (M-TEER) with one of the large devices, either PASCAL P10 or MitraClip XT(R/W) (3rd/4th generation). Methods: A total of 309 PASCAL-treated patients were matched by propensity score to 253 MitraClip-treated patients, resulting in 200 adequately balanced pairs. Procedural, clinical, and echocardiographic outcomes were collected for up to 30 days, including subgroup analysis for mitral regurgitation (MR) etiologies. Results: PASCAL and MitraClip patients were comparable regarding age (80 vs. 79 years), sex (female: 45.5% vs. 50.5%), and MR etiology (degenerative MR: n = 94, functional MR [FMR]: n = 96, mixed MR: n = 10 in each group). Technical success rates were comparable (96.5% vs. 96.0%; p > 0.999). At discharge, the mean gradient was higher (3.3 mmHg vs. 3.0 mmHg; p = 0.038), and the residual mitral valve orifice area was smaller in MitraClip patients (3.0 cm2 vs. 2.3 cm2; p < 0.001). At discharge, the reduction to MR ≤ 2+ was comparable (92.4% vs. 87.8%; p = 0.132). However, reduction to MR ≤ 1+ was more frequently observed in PASCAL patients (67.7% vs. 56.6%; p = 0.029), driven by the FMR subgroup (74.0% vs. 60.0%; p = 0.046). No difference was observed in 30-day mortality (p = 0.204) or reduction in NYHA-FC to ≤II (p > 0.999). Conclusions: Both M-TEER devices exhibited high and comparable rates of technical success and MR reduction to ≤2+. PASCAL may be advantageous in achieving MR reduction to ≤1+ in patients with FMR.

Guideline-Directed Medical Therapy and Survival After TEER for Secondary Mitral Regurgitation With Right Ventricular Impairment.

BACKGROUND: Right ventricular impairment is common among patients undergoing transcatheter edge-to-edge repair for secondary mitral regurgitation (SMR). Adherence to guideline-directed medical therapy (GDMT) for heart failure is poor in these patients. OBJECTIVES: The aim of this study was to evaluate the impact of GDMT on long-term survival in this patient cohort. METHODS: Within the EuroSMR (European Registry of Transcatheter Repair for Secondary Mitral Regurgitation) international registry, we selected patients with SMR and right ventricular impairment (tricuspid annular plane systolic excursion ≤17 mm and/or echocardiographic right ventricular-to-pulmonary artery coupling <0.40 mm/mm Hg). Titrated guideline-directed medical therapy (GDMTtit) was defined as a coprescription of 3 drug classes with at least one-half of the target dose at the latest follow-up. The primary outcome was all-cause mortality at 6 years. RESULTS: Among 1,213 patients with SMR and right ventricular impairment, 852 had complete data on medical therapy. The 123 patients who were on GDMTtit showed a significantly higher long-term survival vs the 729 patients not on GDMTtit (61.8% vs 36.0%; P < 0.00001). Propensity score-matched analysis confirmed a significant association between GDMTtit and higher survival (61.0% vs 43.1%; P = 0.018). GDMTtit was an independent predictor of all-cause mortality (HR: 0.61; 95% CI: 0.39-0.93; P = 0.02 for patients on GDMTtit vs those not on GDMTtit). Its association with better outcomes was confirmed among all subgroups analyzed. CONCLUSIONS: In patients with right ventricular impairment undergoing transcatheter edge-to-edge repair for SMR, titration of GDMT to at least one-half of the target dose is associated with a 40% lower risk of all-cause death up to 6 years and should be pursued independent of comorbidities.

Performance of Transcatheter Direct Annuloplasty in Patients With Atrial and Nonatrial Functional Tricuspid Regurgitation.

BACKGROUND: A novel echocardiography-based definition of atrial functional tricuspid regurgitation (A-FTR) has shown superior outcomes in patients undergoing conservative treatment or tricuspid valve transcatheter edge-to-edge repair. Its prognostic significance for transcatheter tricuspid valve annuloplasty (TTVA) outcomes is unknown. OBJECTIVES: This study sought to investigate prognostic, clinical, and technical implications of A-FTR phenotype in patients undergoing TTVA. METHODS: This multicenter study investigated clinical and echocardiographic outcomes up to 1 year in 165 consecutive patients who underwent TTVA for A-FTR (characterized by the absence of tricuspid valve tenting, midventricular right ventricular [RV] dilatation, and impaired left ventricular ejection fraction) and nonatrial functional tricuspid regurgitation (NA-FTR). RESULTS: A total of 62 A-FTR and 103 NA-FTR patients were identified, with the latter exhibiting more pronounced RV remodeling. Compared to baseline, the tricuspid regurgitation (TR) grade at discharge was significantly reduced (P < 0.001 for both subtypes), and TR ≤II was achieved more frequently in A-FTR (85.2% vs 60.8%; P = 0.001). Baseline TR grade and A-FTR phenotype were independently associated with TR ≤II at discharge and 30 days. In multivariate analyses, A-FTR phenotype was a strong predictor (OR: 5.8; 95% CI: 2.1-16.1; P < 0.001) of TR ≤II at 30 days. At 1 year, functional class had significantly improved compared to baseline (both P < 0.001). One-year mortality was lower in A-FTR (6.5% vs 23.8%; P = 0.011) without significant differences in heart failure hospitalizations (13.3% vs 22.7%; P = 0.188). CONCLUSIONS: Direct TTVA effectively reduces TR in both A-FTR, which is a strong and independent predictor of achieving TR ≤II, and NA-FTR. Even though NA-FTR showed more RV remodeling at baseline, both phenotypes experienced similar symptomatic improvement, emphasizing the benefit of TTVA even in advanced disease stages. Additionally, phenotyping was of prognostic relevance in patients undergoing TTVA.

GLIDE Score: Scoring System for Prediction of Procedural Success in Tricuspid Valve Transcatheter Edge-to-Edge Repair.

BACKGROUND: Tricuspid valve transcatheter edge-to-edge repair (T-TEER) is the most widely used transcatheter therapy to treat patients with tricuspid regurgitation (TR). OBJECTIVES: The aim of this study was to develop a simple anatomical score to predict procedural outcomes of T-TEER. METHODS: All patients (n = 168) who underwent T-TEER between January 2017 and November 2022 at 2 centers were included in the derivation cohort. Additionally, 126 patients from 2 separate institutions served as a validation cohort. T-TEER was performed using 2 commercially available technologies. Core laboratory assessment of procedural transesophageal echocardiograms was used to determine septolateral and anteroposterior coaptation gap, leaflet morphology, septal leaflet length and retraction, chordal structure density, tethering height, en face TR jet morphology and TR jet location, image quality, and the presence of intracardiac leads. A scoring system was derived using univariable and multivariable logistic regression. Endpoints assessed were immediate postprocedural TR reduction ≥2 grades and TR grade moderate or less. RESULTS: The median age was 82 years (Q1-Q3: 78-84 years); 48% of patients were women; and patients presented with severe (55%), massive (36%), and torrential (8%) TR. Five variables (septolateral coaptation gap, chordal structure density, en face TR jet morphology, TR jet location, and image quality) were identified as best predicting procedural outcome and were incorporated in the GLIDE (Gap, Location, Image quality, density, en-face TR morphology) score (range 0-5). TR reduction ≥2 grades and TR grade moderate or less were observed in >90% of patients with GLIDE scores of 0 and 1 and in only 5.6% and 16.7% of those with GLIDE scores ≥4. The GLIDE score was then externally validated in a separate cohort (area under the curve: 0.77; 95% CI: 0.69-0.86). TR reduction significantly correlated with functional improvement assessed by NYHA functional class and 6-minute walk distance at 3 months. CONCLUSIONS: The GLIDE score is a simple, 5-component score that is readily obtained during patient imaging and can predict successful T-TEER.

Artificial intelligence-analyzed computed tomography in patients undergoing transcatheter tricuspid valve repair.

BACKGROUND: Baseline right ventricular (RV) function derived from 3-dimensional analyses has been demonstrated to be predictive in patients undergoing transcatheter tricuspid valve repair (TTVR). The complex nature of these cumbersome analyses makes patient selection based on established imaging methods challenging. Artificial intelligence (AI)-driven computed tomography (CT) segmentation of the RV might serve as a fast and predictive tool for evaluating patients prior to TTVR. METHODS: Patients suffering from severe tricuspid regurgitation underwent full cycle cardiac CT. AI-driven analyses were compared to conventional CT analyses. Outcome measures were correlated with survival free of rehospitalization for heart-failure or death after TTVR as the primary endpoint. RESULTS: Automated AI-based image CT-analysis from 100 patients (mean age 77 ± 8 years, 63% female) showed excellent correlation for chamber quantification compared to conventional, core-lab evaluated CT analysis (R 0.963-0.966; p < 0.001). At 1 year (mean follow-up 229 ± 134 days) the primary endpoint occurred significantly more frequently in patients with reduced RV ejection fraction (EF) <50% (36.6% vs. 13.7%; HR 2.864, CI 1.212-6.763; p = 0.016). Furthermore, patients with dysfunctional RVs defined as end-diastolic RV volume > 210 ml and RV EF <50% demonstrated worse outcome than patients with functional RVs (43.7% vs. 12.2%; HR 3.753, CI 1.621-8.693; p = 0.002). CONCLUSIONS: Derived RVEF and dysfunctional RV were predictors for death and hospitalization after TTVR. AI-facilitated CT analysis serves as an inter- and intra-observer independent and time-effective tool which may thus aid in optimizing patient selection prior to TTVR in clinical routine and in trials.

Prognostic Implications of Residual Tricuspid Regurgitation Grading After Transcatheter Tricuspid Valve Repair.

BACKGROUND: The safety profile of transcatheter tricuspid valve (TTV) repair techniques is well established, but residual tricuspid regurgitation (TR) remains a concern. OBJECTIVES: The authors sought to assess the impact of residual TR severity post-TTV repair on survival. METHODS: We evaluated the survival rate at 2 years of 613 patients with severe isolated functional TR who underwent TTV repair in TRIGISTRY according to the severity of residual TR at discharge using a 3-grade (mild, moderate, and severe) or 4-grade scheme (mild, mild to moderate, moderate to severe, and severe). RESULTS: Residual TR was none/mild in 33%, moderate in 52%, and severe in 15%. The 2-year adjusted survival rates significantly differed between the 3 groups (85%, 70%, and 44%, respectively; restricted mean survival time [RMST]: P = 0.0001). When the 319 patients with moderate residual TR were subdivided into mild to moderate (n = 201, 33%) and moderate to severe (n = 118, 19%), the adjusted survival rate was also significantly different between groups (85%, 80%, 55%, and 44%, respectively; RMST: P = 0.001). Survival was significantly lower in patients with moderate to severe residual TR compared to patients with mild to moderate residual TR (P = 0.006). No difference in survival rates was observed between patients with no/mild and mild to moderate residual TR (P = 0.67) or between patients with moderate to severe and severe residual TR (P = 0.96). CONCLUSIONS: The moderate residual TR group was heterogeneous and encompassed patients with markedly different clinical outcomes. Refining TR grade classification with a more granular 4-grade scheme improved outcome prediction. Our results highlight the importance of achieving a mild to moderate or lower residual TR grade during TTV repair, which could define a successful intervention.

Congestion patterns in severe tricuspid regurgitation and transcatheter treatment: Insights from a multicentre registry.

AIMS: While invasively determined congestion holds mechanistic and prognostic significance in acute heart failure (HF), its role in patients with tricuspid regurgitation (TR)-related right- heart failure (HF) undergoing transcatheter tricuspid valve intervention (TTVI) is less well established. A comprehensive understanding of congestion patterns might aid in procedural planning, risk stratification, and the identification of patients who may benefit from adjunctive therapies before undergoing TTVI. The aim of this study was to investigate the role of congestion patterns in patients with severe TR and its implications for TTVI. METHODS AND RESULTS: Within a multicentre, international TTVI registry, 813 patients underwent right heart catheterization (RHC) prior to TTVI and were followed up to 24 months. The median age was 80 (interquartile range 76-83) years and 54% were women. Both mean right atrial pressure (RAP) and pulmonary capillary wedge pressure (PCWP) were associated with 2-year mortality on Cox regression analyses with Youden index-derived cut-offs of 17 mmHg and 19 mmHg, respectively (p < 0.01 for all). However, RAP emerged as an independent predictor of outcomes following multivariable adjustments. Pre-interventionally, 42% of patients were classified as euvolaemic (RAP <17 mmHg, PCWP <19 mmHg), 23% as having left-sided congestion (RAP <17 mmHg, PCWP ≥19 mmHg), 8% as right-sided congestion (RAP ≥17 mmHg, PCWP <19 mmHg), and 27% as bilateral congestion (RAP ≥17 mmHg, PCWP ≥19 mmHg). Patients with right-sided or bilateral congestion had the lowest procedural success rates and shortest survival times. Congestion patterns allowed for discerning specific patient's physiology and specifying prognostic implications of right ventricular to pulmonary artery coupling surrogates. CONCLUSION: In this large cohort of invasively characterized patients undergoing TTVI, congestion patterns involving right-sided congestion were associated with low procedural success and higher mortality rates after TTVI. Whether pre-interventional reduction of right-sided congestion can improve outcomes after TTVI should be established in dedicated studies.

Role of preexisting right ventricular remodeling in symptoms and prognosis after transcatheter tricuspid valve repair.

BACKGROUND: Severe tricuspid regurgitation (TR) is associated with chronic volume overload and right ventricular remodeling (RVR). Transcatheter tricuspid valve repair (TTVr) reduces TR and can improve quality of life (QoL), but the role of preprocedural RVR on TTVr outcomes remains unclear. AIMS: To investigate the role of RVR on outcomes after TTVr for severe TR. METHODS: Consecutive patients undergoing TTVr (61% edge-to-edge vs. 39% direct annuloplasty) for severe TR were retrospectively compared by preexisting RVR which was defined as dilation of RV mid-level diameter (> 35 mm) according to guidelines. QoL was evaluated using NYHA class, Minnesota Living with Heart Failure Questionnaire (MLHFQ), 36-Item Short Form Health Survey (SF-36), and 6-min walking distance (6MWD) 1-month after TTVr. Mid-term mortality and heart failure (HF) hospitalization were assessed through 1 year. RESULTS: RVR was present in 137 of 223 patients (61%). Symptoms and QoL improved equally in both groups: ≥ 1 NYHA class (57% vs. 65% of patients with vs. without RVR, respectively), 6MWD (36% vs. 34%), MLHFQ (81% vs. 69%), and SF-36 (68% vs. 65%) improvement. One-year mortality and HF hospitalization were significantly higher in patients with RVR (24% and 30%, respectively) than in patients without (8% and 13%, both p < 0.05). In multivariable analysis, RVR was independently associated with mortality (HR 2.3, 95%CI (1.0-5.0), p = 0.04) and the combined endpoint of mortality or rehospitalization (HR 2.0, 95%CI (1.1-3.8), p = 0.03). CONCLUSIONS: TTVr was associated with significant QoL improvement after 1 month, irrespective of RVR. Despite increased mortality and rehospitalization for heart failure, TTVr in the presence of RVR still provides substantial symptomatic benefit for patients with severe TR.

Association of pulmonary hypertension with the outcome in patients undergoing edge-to-edge mitral valve repair.

OBJECTIVES: The association of pulmonary hypertension (PH) with the outcome after mitral transcatheter edge-to-edge repair (M-TEER) focusing on the new ESC/ERS guidelines definition for PH. BACKGROUND: PH is frequently found in patients with mitral regurgitation and is associated with lower survival rates. Recent studies were based on echocardiographic parameters, but results based on invasive haemodynamics differentiating distinct types of PH using the new definition for PH are missing. METHODS: 449 consecutive M-TEER-treated patients from December 2009 to February 2015 were included in this retrospective analysis. All patients were stratified by the distinct types of PH (no PH, precapillary PH, isolated postcapillary PH, combined post-PH and precapillary PH) according to the definitions of the ESC/ERS guidelines for the diagnosis of PH from 2015 (meanPA cut-off <25 mm Hg, pulmonary capillary wedge pressure (PCWP) cut-off ≤15 mm Hg, diastolic pulmonary gradient cut-off ≥7 mm Hg or pulmonary vascular resistance (PVR) >3 WU) and 2022 (meanPA cut-off ≤20 mm Hg, PCWP cut-off ≤15 mm Hg, PVR cut-off ≥3 WU). RESULTS: Patients with any type of PH (2015: meanPA cut-off 25 mm Hg; 2022: meanPA cut-off >20 mm Hg) showed a higher risk of death after M-TEER compared with patients with no PH (2015: HR 1.61 (95% CI 1.25 to 2.07); p<0.001 and 2022: HR 2.09 (95% CI 1.54 to 2.83); p<0.001). Based on the new PH definition, each PH subgroup showed a lower survival after M-TEER compared with patients with no PH. Echocardiographic estimated systolic PAP showed a correlation with invasively measured mean pulmonary artery pressure (mPAP) (r=0.29, p<0.001) and systolic pulmonary arterial pressure (r=0.34,p<0.001). Cox-regression analysis showed higher invasive diastolic, systolic and mean pulmonary pressures were associated with higher all-cause mortality (p<0.001). In addition, invasive measured higher right atrial pressure, lower pulmonary arterial compliance, higher PVR and higher wedge pressure were identified as predictors of all-cause mortality after M-TEER. CONCLUSIONS: The new PH definition discriminates PH groups and mortality better than the old definition. The lower threshold of mPAP of 20mmHg improved prognostication in this cohort of patients.

Frailty, periinterventional complications and outcome in patients undergoing percutaneous mitral and tricuspid valve repair.

BACKGROUND: Frailty is common in elderly and multimorbid patients and associated with increased vulnerability to stressors. METHODS: In a single centre study frailty according to Fried criteria was assessed in consecutive patients before transcatheter mitral and tricuspid valve repair. Postprocedural infections, blood transfusion and bleeding and renal failure were retrospectively assessed from records. Median follow-up time for survival was 560 days (IQR: 363 to 730 days). RESULTS: 90% of 626 patients underwent mitral valve repair, 5% tricuspid valve repair, and 5% simultaneous mitral and tricuspid valve repair. 47% were classified as frail. Frailty was associated with a significantly increased frequency of bleeding (16 vs 10%; p = 0.016), blood transfusions (9 vs 3%; p = < 0.001) and infections (18 vs 10%; p = 0.006), but not with acute kidney injury (20 vs 20%; p = 1.00). Bleeding and infections were associated with longer hospital stays, with a more pronounced effect in frail patients (interaction test p < 0.05, additional 3.2 and 4.1 days in frail patients, respectively). Adjustment for the occurrence of complications did not attenuate the increased risk of mortality associated with frailty (HR 2.24 [95% CI 1.62-3.10]; p < 0.001). CONCLUSIONS: Bleeding complications and infections were more frequent in frail patients undergoing transcatheter mitral and tricuspid valve repair and partly explained the longer hospital stay. Albeit some of the complications were associated with higher long-term mortality, this did not explain the strong association between frailty and mortality. Further research is warranted to explore interventions targeting periprocedural complications to improve outcomes in this vulnerable population.

Incidence and clinical impact of renal failure and bleeding following transcatheter tricuspid valve annuloplasty.

BACKGROUND: Bleeding is the most common complication after percutaneous leaflet-based tricuspid valve repair and associated with acute kidney injury (AKI) and adverse outcome. TTVA with the Cardioband system is a technically more complex procedure; however, frequency and prognostic impact of postinterventional bleeding and renal complications have not been thoroughly examined. AIMS: This study was performed to determine the incidence and clinical impact of bleeding complications (MVARC criteria) and acute kidney injury (KDIGO criteria) following transcatheter tricuspid valve annuloplasty (TTVA). METHODS: In a bi-center retrospective analysis of patients undergoing TTVA between 2018 and 2022, we examined frequency, predictors, and clinical impact of bleeding and renal failure. RESULTS: In 145 consecutive patients, the incidence of any MVARC bleeding was 20.7% (n = 30), whereas major MVARC bleeding occurred in 6.9% (n = 10). The incidence of AKI was 18.6% (n = 27). Risk factors for bleeding events included low baseline hemoglobin and elevated baseline creatinine levels. Risk factors for AKI included diabetes mellitus, arterial hypertension, high body mass index, and elevated baseline creatinine levels. Neither procedure duration nor amount of contrast media was associated with AKI or bleeding. Both bleeding and AKI led to a longer hospital stay. At 3 months, 10.0% (n = 3) of patients with bleeding and 7.8% (n = 9) of patients without bleeding complications died (p = 0.70). Additionally, mortality rate was 7.4% (n = 2) in patients with AKI compared to 8.5% (n = 10) without AKI (p = 0.83). CONCLUSION: While about a fifth of patients undergoing TTVA suffered from postinterventional AKI or bleeding, none of these complications was associated with higher mortality at short-term follow-up. One important risk factor for both complications was chronic renal dysfunction, indicating a high-risk patient population. The most frequent bleeding localizations were the femoral access site, pericardial hemorrhage, and the esophagus, which need explicit attention in periprocedural management.

Multiparametric Monitoring of Disease Progression in Contemporary Patients with Wild-Type Transthyretin Amyloid Cardiomyopathy Initiating Tafamidis Treatment.

BACKGROUND: Recently, a disease modifying therapy has become available for transthyretin amyloid cardiomyopathy (ATTR-CM). A validated monitoring concept of treatment is lacking, but a current expert consensus recommends three clinical domains (clinical, biomarker and ECG/imaging) assessed by several measurable features to define disease progression. METHODS: We retrospectively analyzed data of wild-type ATTR-CM patients initiating tafamidis therapy assessed within our local routine protocol at baseline and 6-months follow-up with respect to the frequency of values beyond the proposed thresholds defining disease progression. Additionally, associations of cardiac magnetic resonance (CMR) tomography with clinical domains were examined within a subgroup. RESULTS: Sixty-two ATTR-CM patients were included (88.7% male, mean age 79 years). In total, 16.1% of patients had progress in the clinical and functional domain, 33.9% in the biomarker domain and 43.5% in the imaging/electrocardiography (ECG) domain, with the latter driven by deterioration of the diastolic dysfunction grade and global longitudinal strain. In total, 35.5% of patients showed progress in none, 35.5% in one, 29.0% in two and no patient in three domains, the latter indicating overall disease progression. A subgroup analysis of twenty-two patients with available baseline and follow-up CMR data revealed an increase in CMR-based extracellular volume by more than 5% in 18.2% of patients, with no significant correlation with progress in one of the clinical domains. CONCLUSIONS: We provide first frequency estimates of the markers of disease progression according to a recent expert consensus statement, which might help refine the multiparametric monitoring concept in patients with ATTR-CM.
