Expansion of the red cell distribution width and evolving iron deficiency as predictors of poor outcome in chronic heart failure.

BACKGROUND An elevated red cell distribution width (RDW) and iron deficiency (ID) at baseline predict enhanced mortality in chronic heart failure (CHF), but little is known about the prognostic implications of their temporal trends. We sought to determine the survival implications of temporal changes in RDW and evolving ID in patients with CHF. METHODS The relation between red cell indices on first consultation and over time with mortality in 274 stable patients with systolic CHF was analysed. The combination of a rising RDW with a falling mean cell volume (MCV) over time defined evolving ID. RESULTS Over a median 12 month period, 51% and 23% of patients had a rise in RDW and evolving ID, respectively. After a median follow-up of 27 months, 60 (22%) patients died. A rising RDW predicted enhanced all-cause mortality (unadjusted HR for 1% per week rise 9.27, 95% CI 3.58 to 24.00, P<0.0001) independently and incrementally to baseline RDW, with an absolute increase >0.02% per week optimally predictive. Evolving ID also related to higher rates of mortality (HR 2.78, 95% CI 1.64 to 4.73, P<0.001) and was prognostically worse than a rising RDW alone (P<0.005). Patients with evolving ID who maintained their Hb levels over time had a 2-fold greater risk of death than those whose Hb levels declined without evolving ID. CONCLUSIONS An expanding RDW and evolving iron deficiency over time predict an amplified risk of death in CHF and should be utilised for risk stratification and/or therapeutically targeted to potentially improve outcomes.

Percutaneous Device Closure of Paravalvular Leak: Combined Experience from the United Kingdom and Ireland

Background: Paravalvular leak (PVL) occurs in 5% to 17% of patients following surgical valve replacement. Percutaneous device closure represents an alternative to repeat surgery. Methods: All UK and Ireland centers undertaking percutaneous PVL closure submitted data to the UK PVL Registry. Data were analyzed for association with death and major adverse cardiovascular events (MACE) at follow-up. Results: Three hundred eight PVL closure procedures were attempted in 259 patients in 20 centers (2004–2015). Patient age was 67±13 years; 28% were female. The main indications for closure were heart failure (80%) and hemolysis (16%). Devices were successfully implanted in 91% of patients, via radial (7%), femoral arterial (52%), femoral venous (33%), and apical (7%) approaches. Nineteen percent of patients required repeat procedures. The target valve was mitral (44%), aortic (48%), both (2%), pulmonic (0.4%), or transcatheter aortic valve replacement (5%). Preprocedural leak was severe (61%), moderate (34%), or mild (5.7%) and was multiple in 37%. PVL improved postprocedure ( P <0.001) and was none (33.3%), mild (41.4%), moderate (18.6%), or severe (6.7%) at last follow-up. Mean New York Heart Association class improved from 2.7±0.8 preprocedure to 1.6±0.8 ( P <0.001) after a median follow-up of 110 (7–452) days. Hospital mortality was 2.9% (elective), 6.8% (in-hospital urgent), and 50% (emergency) ( P <0.001). MACE during follow-up included death (16%), valve surgery (6%), late device embolization (0.4%), and new hemolysis requiring transfusion (1.6%). Mitral PVL was associated with higher MACE (hazard ratio [HR], 1.83; P =0.011). Factors independently associated with death were the degree of persisting leak (HR, 2.87; P =0.037), New York Heart Association class (HR, 2.00; P =0.015) at follow-up and baseline creatinine (HR, 8.19; P =0.001). The only factor independently associated with MACE was the degree of persisting leak at follow-up (HR, 3.01; P =0.002). Conclusion: Percutaneous closure of PVL is an effective procedure that improves PVL severity and symptoms. Severity of persisting leak at follow-up is independently associated with both MACE and death. Percutaneous closure should be considered as an alternative to repeat surgery. # Clinical Perspectives {#article-title-21}Background: Paravalvular leak (PVL) occurs in 5% to 17% of patients following surgical valve replacement.

Calculated plasma volume status and prognosis in chronic heart failure

Plasma volume (PV) expansion hallmarks worsening chronic heart failure (CHF) but no non‐invasive means of quantifying volume status exists. Because weight and haematocrit are related to PV, they can be used to calculate relative PV status (PVS). We tested the validity and prognostic utility of calculated PVS in CHF patients.

94 Percutaneous Mitral Repair in Hypertrophic Cardiomyopathy

Objectives To describe our Centre’s experience of percutaneous mitral repair in Hypertrophic Cardiomyopathy (HCM). Background Exertional dyspnoea in HCM is multi-factorial. Mitral regurgitation (MR) frequently co-exists with or occurs as a result of HCM related haemodynamic abnormalities like left ventricular outflow tract obstruction (LVOTO) and systolic anterior motion of the mitral valve (SAM). Significant MR in HCM can be a major contributor to symptoms. Current interventional treatments which include alcohol septal ablation, surgical myectomy and mitral valve replacement are not always suitable and may be associated with increased risk. Surgical mitral repair using the Alfieri stitch can be successful in reducing MR due to SAM and can improve LVOTO. However, the application of percutaneous mitral repair using MitraClip system (which mimics the Alfieri stitch) in HCM has not been previously documented. We describe our experience of treating six HCM patients with this technique. Methods Percutaneous mitral repair using the MitraClip System (Evalve, Inc., Menlo Park, CA, USA) technology was performed on six HCM patients between 2010–2012. All cases were discussed in a multi-disciplinary team setting beforehand. Patients who were not suitable for conventional treatment were offered this procedure if deemed clinically appropriate. All patients were subsequently followed-up for 12 months. Improvement in exercise capacity was assessed by a combination of clinical history and 6 min walk test. The echocardiographic images and case notes were retrospectively reviewed. Results MitraClip implants were completed successfully without any significant peri-procedure complications in all patients. Our experience suggests that it is associated with low procedural risk and relatively short inpatient stay (average of 4 days including pre-procedure admission the day before procedure). Below is a summary of our outcomes. Abstract 94 Table 1 Case Degree of MR pre-procedure Degree of MR post-procedure Improvement in exercise capacity MR recurrence at 12 months 1 Moderate/Severe Mild Yes(6 weeks after procedure) No 2 Severe Moderate Yes(6 months after procedure) No 3 Severe Moderate/Severe No(6 weeks after procedure) Yes (1 month post procedure) 4 Moderate/Severe Mild Yes(6weeks after procedure) Yes (8 months post procedure) 5 Severe Mild Yes(8 weeks after procedure) No 6 Moderate/Severe Mild No(6 weeks after procedure) No Conclusion Percutaneous mitral repair using MitraClip is feasible and may be performed safely in HCM. This technique can be effective in reducing mitral regurgitation and improving symptoms in HCM. However, MR recurrence was an observed complication in our cohort. Percutaneous mitral repair using the MitraClip technology may have a future role to play in the symptomatic management of HCM. More studies are needed to understand how MitraClip alters haemodynamics in HCM and how that may contribute to symptom improvement.

107 Expansion of the red cell distribution width and evolving iron deficiency as predictors of poor outcome in chronic heart failure

Background Red cell distribution width (RDW) is a surrogate of many aberrations (inflammation, malnutrition, iron deficiency (ID)) that may drive chronic heart failure (CHF) progression. While an elevated RDW and iron deficiency at baseline predict mortality in CHF, little is known about the prognostic implications of their temporal trends. Methods We analysed the relation of red cell indices on first consultation and over time with mortality in 274 outpatients with CHF (mean (±SD) age 70±14 years, LVEF 28±8%, NYHA class 2±1, 54% ischaemic). The combination of a rising RDW and a falling mean cell volume (MCV) identified evolving ID. Results On initial consultation, an RDW >15%, Hb<12.5 g/dl, and MCV <80 fl were evident in 41%, 46%, and 8% of patients. Over a median (±IQR) follow-up of 15±17 months, 60 (22%) patients died. On Cox proportional hazards analyses, a higher RDW independently predicted increased mortality (HR 1.21, p<0.0001). Over time, 51%, 58%, 40%, and 23% of patients had a rise in RDW, a fall in Hb, a fall in MCV, and evolving ID, respectively. A rising RDW predicted death (HR 1.18, p=0.002) independently of baseline RDWs and changes in Hb, with an absolute increase >1% conferring a twofold escalated risk of mortality (Abstract 107 figure 1A). Evolving ID was also associated with poorer survival (HR 2.89, p<0.0001, Abstract 107 figure 1B).Abstract 107 Figure 1 Conclusions An expanding RDW and evolving iron deficiency over time predict an amplified risk of death in CHF and could be utilised for risk stratification or therapeutically targeted to improve outcomes.

17 Radial vs. femoral access in heat-PPCI: MACE and bleeding outcomes - exploring the limitations of observational research

Background Primary Percutaneous Coronary Intervention (PPCI) through the radial artery is considered to be safer in the hands of operators, experienced in that approach. We examined the impact of radial and femoral access in the HEAT-PPCI trial. Methods We compared the primary safety and efficacy outcomes* at 28 days, by final access site used (radial or femoral) and by default operator type. We then specifically assessed outcomes in femoral cases performed by both, default radial and femoral operators. Findings 1804 cases were included in the final analysis. In a simple analysis, radial access was associated with significantly fewer MACE and bleeding events.* When analysed by default operator type, the incidence of MACE and bleeding events were similar.* In the femoral cases done by radial or femoral operators, MACE and bleeding events were significantly worse for the radial operators, potentially explained by less favourable baseline characteristics.* Interpretation In this unselected, real-world population treated with PPCI, default femoral operators, when compared to high volume radial operators, achieved comparable MACE outcomes but at the expense of increased bleeding - mainly minor bleeding. The less favourable outcomes observed for femoral access in the whole population is probably due to its use by radial operators in high risk cases. *See Table Abstract 17 Table 1 Baseline characteristics, Primary efficacy and Safety outcomes (as defined in the HEAT—PPCI trial).

OPTIMAL EUROSCORES FOR PREDICTING INPATIENT DEATHS IN PATIENTS WITH LEFT VENTRICULAR SYSTOLIC DYSFUNCTION UNDERGOING CARDIAC SURGERY

The utility of surgery revascularization in patients (pts) with a low LVEF and operable coronary disease is unclear, highlighting the importance of risk stratification. Whilst the EuroSCORE and Parsonnet score (PS) are established prognosticators, their relative utility and optimal cut-offs in pts
