Purpose: Left ventricular global function index (LVGFI) assessed using cardiac magnetic resonance (CMR) seems promising in the prediction of clinical outcomes. However, the role of the LVGFI is uncertain in patients with heart failure (HF) with dilated cardiomyopathy (DCM). To describe the association of LVGFI and outcomes in patients with DCM, it was hypothesized that LVGFI is associated with decreased major adverse cardiac events (MACEs) in patients with DCM.Materials and Methods: This prospective cohort study was conducted from January 2015 to April 2020 in consecutive patients with DCM who underwent CMR. The association between outcomes and LVGFI was assessed using a multivariable model adjusted with confounders. LVGFI was the primary exposure variable. The long-term outcome was a composite endpoint, including death or heart transplantation.Results: A total of 334 patients (mean age: 55 years) were included in this study. The average of CMR-LVGFI was 16.53%. Over a median follow-up of 565 days, 43 patients reached the composite endpoint. Kaplan–Meier analysis revealed that patients with LVGFI lower than the cutoff values (15.73%) had a higher estimated cumulative incidence of the endpoint compared to those with LVGFI higher than the cutoff values (P = 0.0021). The hazard of MACEs decreased by 38% for each 1 SD increase in LVGFI (hazard ratio 0.62[95%CI 0.43–0.91]) and after adjustment by 46% (HR 0.54 [95%CI 0.32–0.89]). The association was consistent across subgroup analyses.Conclusion: In this study, an increase in CMR-LVGFI was associated with decreasing the long-term risk of MACEs with DCM after adjustment for traditional confounders.

Abstract Funding Acknowledgements Type of funding sources: Foundation. Main funding source(s): The Danish Heart Foundation Background In acute heart failure (AHF), low systolic blood pressure (SBP) has been associated with poor outcome. Less is known of the risk related to normal versus elevated SBP and interaction with left ventricular ejection fraction. Purpose The aim of the present study was to assess the association between baseline SBP and short- and long-term outcome in a large cohort of AHF-patients. Methods A pooled cohort of four randomized controlled trials investigating the vasodilator serelaxin versus placebo in patients admitted with AHF and an SBP from 125 to 180 mmHg. Endpoints were 180-day all-cause mortality and a short-term composite endpoint (worsening heart failure, all-cause mortality or hospital readmission for HF through Day 14). Left ventricular ejection fraction (LVEF) was categorized into HFrEF (<40%) and HFpEF (= >40%). Multivariable Cox regression was used and adjusted for age, sex, baseline body mass index, HFrEF, serum estimated glomerular filtration rate, allocated treatment (placebo/serelaxin), diabetes mellitus, ischemic heart disease, and atrial fibrillation/flutter. Measurements and Main Results A total of 10.533 patients with a mean age of 73 (±12) years and median SBP of 140 (130-150) mmHg were included within mean 8.2 hours from admission. LVEF was assessed in 8493 (81%), and of these, 4294 (51%) had HFrEF. Increasing SBP as a continuous variable was inversely associated with 180-day mortality (HRadjusted: 0.93 [0.88-0.98], p = 0.004 per 10 mmHg increase) and with the composite endpoint (HRadjusted: 0.90 [0.85-0.95], p < 0.0001 per 10 mmHg increase). A significant interaction was observed regarding LVEF, revealing that SBP was not associated with mortality in patients with HFpEF  (HRadjusted: 1.01 [0.94-1.09], p = 0.83 per 10 mmHg increase), but SBP was associated with increased mortality in HFrEF (HRadjusted: 0.80 [0.73-0.88], p < 0.001 per 10 mmHg increase) (Figure). Conclusions Elevated SBP is independently associated with favorable short- and long-term outcome in AHF-patients. The association between SBP and mortality was, however, not present in patients with preserved LVEF. Abstract Figure. Survival plots by SBP and LVEF

Ebstein's Anomaly

Background: We have previously shown that neonates in profound cardiogenic shock due to severe Ebstein’s anomaly can be successfully salvaged with fenestrated right ventricular (RV) exclusion and systemic to pulmonary shunt (modified Starnes procedure). The long-term outcome of single ventricle management in these patients is not known. Methods: We retrospectively reviewed the records of 26 patients who underwent neonatal Starnes procedure between 1989 and 2011. Patient demographics, clinical variables and outcome data were collected. Data is presented as mean ± standard errors or median (interquartile ranges). Results: 26 patients (12, 46% boys) underwent Starnes procedure at 7 (5-9) days of life. All were intubated and on prostacyclin infusion, 24 (92%) were inotrope-dependent and 23 (88%) had no antegrade flow from the RV. Two patients had had prior intervention (one tricuspid annuloplasty and one shunt alone). Three patients underwent non-fenestrated RV exclusion, two (67%) of whom died. Of the remaining 23, 3 (13%) died during the same hospitalization. The 21 neonatal survivors have been followed for 7 (6-8) years. One patient died after Glenn. The remaining 20 have successfully undergone Fontan completion with an indexed pulmonary resistance of 1.8 (1.2-2.3) W/m2 and mean pulmonary pressure of 12 (9-18) mm Hg. At last follow-up, all patients have normal left ventricular function, and all but one patient are in NYHA Class I symptoms. Two patients have required pacemaker implantation, while the rest are in sinus rhythm. Survival at 1, 5 and 10 years are 81±4%, 77±3% and 77±3%, respectively. Conclusion: Long-term single ventricle outcomes amongst neonatal survivors of modified Starnes procedure are excellent. There is reliable remodeling of the excluded RV and excellent function of the left ventricle.

Mustard Procedure

The restoration of the left ventricle as the systemic pump and the lack of sinus node dysfunction (assessment with the Senning or Mustard procedure) have been suggested as the major advantages of the arterial switch procedure. Although the results are encouraging, children will require follow up to assess: long-term left ventricular function; coronary ostial growth; aortic and pulmonic anastomosis growth; long-term aortic valve (anatomical pulmonary valve) dysfunction. A learning curve is inherent to a new surgical procedure. During this learning period, both surgical technique and patient selection criteria improve, resulting in reduced morbidity and mortality. The arterial switch procedure for TGA is certainly not an exception. Expert nursing assessment and intervention during the postoperative period is imperative and may reflect on the long-term outcome of these children.

Abstract Funding Acknowledgements ÖNB Jubiläumsfondsprojekt Nr. 15974, ISR grant by Boston Scientific, St. Paul, MN, USA Background Central sleep apnea (CSA) in pacing induced cardiomyopathy (PICM) is poorly studied. Specifically, it is unknown whether upgrading from right ventricular pacing (RVP) to cardiac resynchronisation therapy (CRT) improves CSA. Methods Fifty-three patients with impaired left ventricular ejection fraction, frequent right ventricular pacing due to high-grade atrioventricular block and heart failure symptoms despite optimal medical therapy underwent upgrading to CRT. Within one month after left ventricular lead implantation (but still not activated), sleep apnea was assessed in all participants by single-night polysomnography (PSG). Nineteen patients with moderate or severe CSA defined by an apnea hypopnea index (AHI) > 15 events per hour were re-scheduled for a follow up PSG 3-5 months after initiation of cardiac resynchronization therapy. Of this cohort, thirteen patients with stable mild heart failure agreed to be randomized to CRT versus RVP in a cross-over design. Results CSA (AHI > 5 events per hour) was diagnosed in 26 (49.1%), OSA in 16 (30.2%) patients suffering from PICM . Eleven (20.8%) patients did not have any form of sleep apnea. Moderate to severe CSA (AHI > 15 events per hour) was significantly improved (without specific CPAP therapy) by 102 (96-172) days of CRT: AHI decreased from 39.4 events per hour at baseline to 21.6 by CRT (p < 0.001). Furthermore, CRT led to a substantial decrease in left ventricular endsystolic volumes: baseline 141 ml (103-155), significant improvement under CRT (102 ml, 65-138; p < 0.001), whereas no effect with ongoing RV-pacing (147 ml, 130-161; p = 0.865). Preexistent CSA did not affect the structural response of CRT (56.5% in patients with CSA, 62.5% of patients with obstructive sleep apnea and 54.5% in patients without sleep apnea; p = 0.901) and had no impact on major adverse cardiac events (p = 0.412) and/or survival (p = 0.623) during long-term follow-up. Conclusions CSA is highly prevalent in patients with PICM and is significantly improved by upgrading to CRT. Preexistent CSA does not hamper structural improvement and long-term outcome after upgrading to CRT. Thus, CSA seems to occur as a consequence of PICM, rather than as a pathophysiological mediator.
