Abstract Aims Risk stratification of patients with new‐onset acute heart failure (AHF) is important but remains challenging. In the present study, we evaluated the prognostic value of a new multiparameter right ventricular dysfunction (RVD) score. Methods and results Patients (n = 210) hospitalized due to new‐onset AHF between 2015 and 2018 were retrospectively included. Mean age was 56 ± 10 years, 24% were female and median left ventricular ejection fraction was 28% (interquartile range 20; 34%). The RVD score, tricuspid annular plane systolic excursion (TAPSE), and fractional area change (FAC) were determined at index hospitalization and after therapy titration. The 4‐point RVD score included reduced TAPSE, right ventricular enlargement, moderate or severe tricuspid regurgitation and increased central venous pressure. The study endpoint was a composite of all‐cause mortality, left ventricular assist device implantation, and heart transplantation. After 60 months median follow‐up time, 53 (25%) patients met the endpoint. At index hospitalization, there were no significant differences in any echocardiographic parameter between patients with and without the endpoint. After therapy titration, there were differences in TAPSE (16 vs. 19 mm, P = 0.001), FAC (33 vs. 40%, P

Abstract Aims Due to the shortage of heart donors, increasing numbers of heart transplantation (HTx) candidates are receiving long‐term mechanical circulatory support (MCS) as bridge‐to‐transplantation. Treatment with MCS is associated with increased formation of anti‐human leukocyte antigen antibodies (allosensitization), but whether this affects post‐HTx outcomes is unclear. Methods and results We included all adult patients who received long‐term MCS as bridge‐to‐transplantation and underwent subsequent HTx at our centre between 2008 and 2018. We also enrolled medically treated HTx recipients without prior MCS as controls. These controls were matched by age, sex, diagnosis, and transplantation era. Outcome parameters were compared between the two study groups. A total of 126 patients (48 ± 15 years, 84% male) were included of whom 64 were bridged with MCS and 62 were matched controls. Pre‐HTx allosensitization occurred more frequently in the MCS group than in the control group (27% vs. 11%, P = 0.03). At post‐HTx year 10, the overall survival probability was 84% among patients treated with MCS and 90% among those medically managed (P = 0.32). At post‐HTx year 1, freedom from treated rejections (≥ISHLT 2R) was 69% in the MCS group and 70% in the control group (P = 0.94); and freedom from any rejection was 8% and 5%, respectively (P = 0.98). There were no differences in renal function or cardiac allograft vasculopathy (grade ≥ 1) between groups at 1, 3, and 5 years post‐HTx. Conclusions Although patients treated with MCS had a higher frequency of pre‐HTx allosensitization, there were no significant differences in post‐HTx graft survival, biopsy‐proven rejections, or renal function as compared with patients not bridged with MCS.

Background Cardiac involvement can be an initial manifestation in sarcoidosis. However, little is known about the association between various clinical phenotypes of cardiac sarcoidosis (CS) and outcomes. We aimed to analyze the relation of different clinical manifestations with outcomes of CS and to investigate the relative importance of clinical features influencing overall survival. Methods and Results A retrospective cohort of 141 patients with CS enrolled at 2 Swedish university hospitals was studied. Presentation, imaging studies, and outcomes of de novo CS and previously known extracardiac sarcoidosis were compared. Survival free of primary composite outcome (ventricular arrhythmias, heart transplantation, or death) was assessed. Machine learning algorithm was used to study the relative importance of clinical features in predicting outcome. Sixty‐two patients with de novo CS and 79 with previously known extracardiac sarcoidosis were included. De novo CS showed more advanced New York Heart Association class (P=0.02), higher circulating levels of NT‐proBNP (N‐terminal pro‐B‐type natriuretic peptide) (P

Abstract Aims Renal dysfunction in patients with heart failure (HF) has traditionally been attributed to declining cardiac output and renal hypoperfusion. However, other central haemodynamic aberrations may contribute to impaired kidney function. This study assessed the relationship between invasive central haemodynamic measurements from right‐heart catheterizations and measured glomerular filtration rate (mGFR) in advanced HF. Methods and results All patients referred for heart transplantation work‐up in Sweden between 1988 and 2019 were identified through the Scandiatransplant organ‐exchange organization database. Invasive haemodynamic variables and mGFR were retrieved retrospectively. A total of 1001 subjects (49 ± 13 years; 24% female) were eligible for the study. Analysis of covariance adjusted for age, sex, and centre revealed that higher right atrial pressure (RAP) displayed the strongest relationship with impaired GFR [β coefficient −0.59; 95% confidence interval (CI) –0.69 to −0.48; P

Abstract This case presents a challenging diagnosis of EGPA presenting as eosinophilic myocarditis. It is a condition that can mimic many other diseases and where prompt diagnosis and early treatment is essential for recovery. The diagnosis was made after an endomyocardial biopsy (EMB) and showed the importance of EMB in the diagnostic work‐up.

Abstract Aims Functional mitral regurgitation (MR) (FMR) is common in heart failure with reduced ejection fraction and worsens morbidity and mortality, even when mild. The CARILLON® mitral contour system (Cardiac Dimensions, Kirkland, WA, USA), a mitral annuloplasty device delivered percutaneously to the coronary sinus, is designed to reduce the mitral annular dimension by virtue of the close anatomic relationship between the coronary sinus and the posterior mitral annulus. We performed a comprehensive individual patient data meta‐analysis of all studies that used CARILLON® device vs. control that have measured mitral regurgitation severity, left ventricular (LV) remodelling, functional status, and heart failure‐related outcomes in heart failure with reduced ejection fraction patients. Methods and results The Cochrane Central Register of Controlled Trials, MEDLINE, and EMBASE were searched in July 2020. Primary outcomes of interest were measures of MR severity, LV remodelling, New York Heart Association functional class and heart failure‐related outcomes [mortality and heart failure hospitalization (HFH) during follow up]. All data were received as individual patient and individual time point data‐points. Mean differences and 95% confidence intervals (CIs) were calculated for continuous data using a fixed‐effects model. Three studies (REDUCE FMR, TITAN and TITAN II) enrolling 209 participants were identified and included. Pooled analysis showed that, compared with control, CARILLON® device significantly improved both MR volume (mean difference MD ‐9.20, 95% C.I. −16.11 to −2.29 mL, P = 0.009) and MR grade (MD ‐1.12, 95% CI −1.36 to −0.88, P
