Introduction: Left bundle branch pacing (LBBP) is a novel pacing method and has been proven to have low and stable pacing thresholds. However, data on large numbers of patients with long-term follow-up is still needed to evaluate its feasibility and safety. Hypothesis: To evaluate the feasibility and safety of LBBP in a large sample with long-term follow up. Methods: This study prospectively enrolled 632 consecutive patients with left bundle branch block, AV block or sick sinus syndrome with attempted LBBP from April 2017 to July 2019. Pacing parameters, ECG, echocardiographic measurements, complications were assessed at implant, and during follow-up of 1, 6, 12 and 24 months. Results: LBBP was successful in 618/632 (97.8%) patients according to the strict criteria for LBB capture. Mean follow-up time was 17.8±6.9 months. LBB capture threshold at implant was 0.65±0.27 [email protected] and 0.71±0.35 [email protected] at 2-year follow-up (n=166). Left ventricular ejection fraction were improved in QRS≥120ms and <120ms groups (60.62±14.22% vs. 63.95±11.29 %, p<0.001; 49.77±17.58 % vs. 58.58±12.79 %, p<0.001; respectively). The number of patients with moderate and sever tricuspid regurgitation decreased at 1-year (120 to 66;28 to 16; respectively). Permanent right bundle branch injury occurred in 55 (8.9%) patients. LBB capture threshold increased greater than 2 V in 6 patients, loss of capture in 2 patients, two lead dislodgements requiring operative revision within 1 month after implantation during 2-years follow-up. Conclusions: Feasibility and safety of LBBP were confirmed by this large sample size and long-term follow-up study. It is a reliable physiologic method for standards pacing indications.

Large Observational Study

Background - Left bundle branch pacing (LBBP) is a novel pacing method and has been observed to have low and stable pacing thresholds in prior small short-term studies. The objective of this study was to evaluate the feasibility and safety of LBBP in a large consecutive diverse group of patients with long-term follow up. Methods - This study prospectively enrolled 632 consecutive pacemaker patients with attempted LBBP from April 2017 to July 2019. Pacing parameters, complications, ECG, and echocardiographic measurements were assessed at implant, and during follow-up of 1, 6, 12 and 24 months. Results - LBBP was successful in 618/632 (97.8%) patients according to strict criteria for LBB capture. Mean follow-up time was 18.6±6.7 months. 231 patients had follow-up over 2 years. LBB capture threshold at implant was 0.65±0.27 [email protected] and 0.69±0.24 [email protected] at 2-year follow-up. A significant decrease in QRS duration was observed in patients with LBBB (167.22 ± 18.99ms vs. 124.02 ± 24.15ms, p<0.001). Post implantation left ventricular ejection fraction improved in patients with QRS≥120ms (48.82±17.78 % vs. 58.12±13.04 %, p<0.001). The number of patients with moderate and severe tricuspid regurgitation decreased at 1-year. Permanent right bundle branch injury occurred in 55 (8.9%) patients. LBB capture threshold increased to more than 3 V or loss of bundle capture in 6 patients (1%), 2 patients of them had loss of conduction system capture. Two patients required lead revision due to dislodgement. Conclusions - This large observational study suggests that LBBP is feasible with high success rates and low complication rates during long term follow up. Therefore, LBBP appears to be a reliable method for physiological pacing for patients with either a bradycardia or heart failure pacing indication.

Aim To study a relationship of several factors (clinical and genetical markers) with unfavorable outcomes in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) in long-term follow-up.Material and methods This full-design, prospective study included 415 patients with NSTE-ACS. 266 patients were evaluated for the presence of multifocal atherosclerosis (MFA). Typing of polymorphic variants rs1041981 LTA, rs1800629 TNF, rs4986790, and rs498679 TLR4, and also rs3024491 and rs1800872 IL10 was performed. Follow-up period lasted for 67±4 months. By the end of this period, information about clinical outcomes for 396 patients became available.Results During the entire follow-up period, unfavorable outcomes were observed in 239 (57.5 %) patients with NSTE-ACS. The following clinical signs were associated with unfavorable outcomes: history of myocardial infarction, age >56 years, left ventricular ejection fraction (LV EF) ≤50 % and GRACE score ≥100, significant stenosis of brachiocephalic arteries, MFA, carriage of genotype А / А rs1041981 LTA (OR, 6.1; р=0.02) and allele А (OR, 1.9; р=0.01). According to results of a multifactorial analysis, the most significant predictors included LV EF <50 %, MFA, and carriage of genotype А / А rs1041981 LTA.Conclusion Stratification of patients with NSTE-ACS into groups of high or low risk for having an unfavorable outcome within the next 6 years is possible using the prognostic model developed and presented in this study. The model includes the following signs: LV EF <50 %, MFA, and carriage of genotype А / А rs1041981 LTA.

Abstract Aims Several studies have shown that Takotsubo syndrome (TTS) secondary to neurological disorders is associated with higher rate of in-hospital complications. Imaging brain studies found that atrophy or damage of some regions and their altered connectivity with other brain regions are typical features of TTS patients. The aim of the study is to evaluate rates of in hospital and long-term Follow-up events in TTS patients with history or acute cerebrovascular events (CVE). Methods and results 395 consecutive patients were enrolled in a multicentre prospective registry. History, clinical data, echocardiographic parameters and in-hospital and long-term follow-up events of all patients were evaluated. Prevalence of cerebrovascular events among TTS patients was 9.4% (num = 37). Compared to the control group, these patients were older (80 ± 7 vs. 71 ± 12, P = 0.01) and predominantly men (24% vs. 9%, P = 0.01). No differences in term of cardiovascular risk factors and left ventricular ejection fraction at admission and discharge were found among the two groups. The prevalence of physical stressor was higher in the CVE group (67% vs. 44% P = 0.01). The incidence of in-hospital adverse events was higher in the CVE than in the control one (70% vs. 29%), mainly driven by higher rate of Cardiogenic shock (19 vs. 8% P = 0.01) and in-hospital death (19 vs. 4%, P = 0.01). At long-term follow-up, patients in CVE group hat higher mortality rate (38% vs. 20% P = 0.01)). Patients presenting with acute CVE, 10 out of 37 patients (27%) when compared with chronic CVE had higher in-hospital mortality (40% vs. 11% P = 0.01). Conclusions TTS patients with history or acute cerebrovascular events had higher rate of in-hospital events and death at long-term follow-up. Acute cerebrovascular events in the setting of TTS are featured with worst prognosis.

Abstract Background Heart failure is becoming the most prominent cause of death among patients with Duchenne Muscular Dystrophy (DMD) and end-stage cardiomyopathy (CMP). Implantation of left ventricular assist devices (LVAD) as destination therapy (DT) in this group of patients is still matter of debate. No current data are available on long-term follow- up of young patients. Purpose The aim of this study was to evaluate the long-term outcome of LVAD in DMD end stage heart failure (HF) compared to a group treated optimal medical treatment (OMT) with inotropes Methods All patients affected by DMD patients presenting with end-stage HF receiving OMT or LVAD have been reviewed. All data about characteristics of HF at presentation including assessment of nutritional status and respiratory function, left ventricular ejection fraction, brain natriuretic peptide, serum sodium, in-hospital treatment and long term follow up have been collected. OMT group was constituted by 4 patients matching implantation VAD criteria but not eligible or refusing treatment. Survival was represented by Kaplan Meier analysis. Results A total of 12 DMD patients with end-stage CMP were considered for this analysis. 8 have been implanted with LVAD during the period from 2011 until mid-2017 and compared with 4 treated with OMT. Mean systolic pressure was 103 versus 91 mmHg in those not receiving LVAD (p=0.2), and left ventricular ejection fraction at the time of presentation was 16‰ for LVAD group and 22‰ for the second group (p=0.1). LVADs improved survival throughout follow-up for patients undergoing baseline inotropic infusions (P=0.0014); for the LVAD group versus the OMT group, 1-month survival was 100‰ and 67‰ respectively and 2-month survival was 100‰ versus 0‰. For LVAD group survival was 86‰ at one year, 71‰ at 2 years and 48‰ at 5 years from implantation. Analysis on short and long-term follow-up showed significant improvement of survival in DMD patients treated with LVAD (log rank<0.001), with a 5-year increase in life expectancy. Conclusions LVAD improved outcomes in patients with LVAD when compared to those without. Long-term follow-up was similar to DT LVAD adult population. Further studies are necessary to confirm these data.

Abstract Background Takotsubo syndrome (TTS) is featured by an acute and reversible left ventricular dysfunction and can be complicated by cardiogenic shock. Intra-aortic balloon pumping (IABP) use in this setting is controversial, and few data are available from large populations. Aim of this study was therefore to evaluate short- and long-term impact of IABP on mortality in TTS complicated by cardiogenic shock. Methods The GEIST registry is a multicenter, international registry on TTS involving 38 centers from Germany, Italy and Spain. Between 2006 and 2017, 2250 consecutive patients with TTS were enrolled. Results Of the 2250 patients, 211 (9%) experienced cardiogenic shock during hospitalization for TTS. Admission left ventricular ejection fraction (LVEF) was 30±15% and systolic blood pressure was 90±35 mmHg. Apical ballooning pattern was found in 77%, mid-ventricular/basal pattern in 11%, and 2% of the patients, respectively. Forty-two patients out of 211 (19%) received IABP after coronary angiography. Patients receiving IABP compared to standard medical therapy did not differ in terms of age, gender, cardiovascular risk factors and admission LVEF. No differences were found in term of in-hospital mortality (9.5% vs 17% p=0.35), length of hospitalization (19.3 vs 16.3 days p=0.34), need of invasive ventilation (35% vs 41% p=0.60), stroke (4.7% vs 11% p=0.17) and LV thrombus (0.5% vs 1.7%, p=0.98). At long-term follow-up, with a median of 2 years, overall mortality in patients with cardiogenic shock and TTS was 34.1%. Mortality was not different between the IABP and the control group (33.7% vs 35.0%; p=0.85). Conclusions In this large multicenter observational registry, the use of IABP has no impact on mortality at short and long-term follow-up. Further studies are needed to evaluate the best therapeutic strategy in TTS complicated by cardiogenic shock.
