- OBJECTIVES: This study sought to compare sex difference for procedural aspects and complications in the European Society of Cardiology CRT Survey II, exploring whether adverse events were related to the type of CRT device implanted.BACKGROUND: Sex-related differences in procedural aspects and complications in patients undergoing cardiac resynchronization therapy (CRT) implantation has not been explored in a real-life population.METHODS: A post-hoc analysis of procedural data and complications in different sexes and factors associated with events was performed from data collected in the European Society of Cardiology CRT Survey II.RESULTS: Of all patients (n = 11,088) included, 24.3% were women. The mean age (70 years of age) of male and female recipients was similar. Female patients more frequently had an idiopathic cardiomyopathy (67.4% vs. 44.1%) and fewer comorbidities, including atrial fibrillation (34.8% vs. 42.8%), diabetes (29.1% vs. 32.1%), chronic obstructive lung disease (10.3% vs. 12.6%), and renal failure (28.7% vs. 31.9%), compared with men. More women compared with men had a pacemaker (56.6% vs. 46.3%) and much less often an implantable cardioverter-defibrillator (CRT-D) (19.0% vs. 34.7%) implant. Periprocedural event rate was the highest in women with CRT with defibrillator (7.1% vs. 4.8% in men), followed by women with a CRT with pacing (5.5% vs. 4.4% in men). The higher periprocedural event rate in CRT-D women was attributable primarily to the occurrence of pneumothorax (1.4%), coronary sinus dissection (2.1%), and pericardial tamponade (0.3%). The rate of in-hospital major adverse events (6.0%) and complications necessitating reoperation (4.0%) was not different among sex and device type.CONCLUSIONS: Women are more likely to experience adverse procedure-related events during CRT implantation. Thus, preventive strategies should be employed to minimize complication rate.

- Background Cardiac resynchronisation therapy (CRT) reduces morbidity and mortality in appropriately selected patients with heart failure and is strongly recommended for such patients by guidelines. A European Society of Cardiology (ESC) CRT survey conducted in 2008-2009 showed considerable variation in guideline adherence and large individual, national and regional differences in patient selection, implantation practice and follow-up. Accordingly, two ESC associations, the European Heart Rhythm Association and the Heart Failure Association, designed a second prospective survey to describe contemporary clinical practice regarding CRT. Methods and results A survey of the clinical practice of CRT-P and CRT-D implantation was conducted from October 2015 to December 2016 in 42 ESC member countries. Implanting centres provided information about their hospital and CRT service and were asked to complete a web-based case report form collecting information on patient characteristics, investigations, implantation procedures and complications during the index hospitalisation. The 11 088 patients enrolled represented 11% of the total number of expected implantations in participating countries during the survey period; 32% of patients were aged >= 75 years, 28% of procedures were upgrades from a permanent pacemaker or implantable cardioverter-defibrillator and 30% were CRT-P rather than CRT-D. Most patients (88%) had a QRS duration >= 130 ms, 73% had left bundle branch block and 26% were in atrial fibrillation at the time of implantation. Large geographical variations in clinical practice were observed. Conclusion CRT Survey II provides a valuable source of information on contemporary clinical practice with respect to CRT implantation in a large sample of ESC member states. The survey permits assessment of guideline adherence and demonstrates variations in patient selection, management, implantation procedure and follow-up strategy.

Acute Hemodynamic Effects of Simultaneous and Sequential Multi-Point Pacing in Heart Failure Patients With an Expected Higher Rate of Sub-response to Cardiac Resynchronization Therapy : Results of Multicenter SYNSEQ Study

- The aim of the SYNSEQ (Left Ventricular Synchronous vs. Sequential MultiSpot Pacing for CRT) study was to evaluate the acute hemodynamic response (AHR) of simultaneous (3P-MPP syn) or sequential (3P-MPP seq) multi-3-point-left-ventricular (LV) pacing vs. single point pacing (SPP) in a group of patients at risk of a suboptimal response to cardiac resynchronization therapy (CRT). Twenty five patients with myocardial scar or QRS ≤ 150 or the absence of LBBB (age: 66 ± 12 years, QRS: 159 ± 12 ms, NYHA class II/III, LVEF ≤ 35%) underwent acute hemodynamic assessment by LV + dP/dtmax with a variety of LV pacing configurations at an optimized AV delay. The change in LV + dP/dt max (%ΔLV + dP/dt max) with 3P-MPP syn (15.6%, 95% CI: 8.8%-22.5%) was neither statistically significantly different to 3P-MPP seq (11.8%, 95% CI: 7.6-16.0%) nor to SPP basal (11.5%, 95% CI:7.1-15.9%) or SPP mid (12.2%, 95% CI:7.9-16.5%), but higher than SPP apical (10.6%, 95% CI:5.3-15.9%, p = 0.03). AHR (defined as a %ΔLV + dP/dt max ≥ 10%) varied between pacing configurations: 36% (9/25) for SPP apical, 44% (11/25) for SPP basal, 54% (13/24) for SPP mid, 56% (14/25) for 3P-MPP syn and 48% (11/23) for 3P-MPP seq.Fifteen patients (15/25, 60%) had an AHR in at least one pacing configuration. AHR was observed in 10/13 (77%) patients with a LBBB but only in 5/12 (42%) patients with a non-LBBB (p = 0.11). To conclude, simultaneous or sequential multipoint pacing compared to single point pacing did not improve the acute hemodynamic effect in a suboptimal CRT response population.Clinical Trial Registration: ClinicalTrials.gov, identifier: NCT02914457.
