Background. Right ventricular pacing (RVP) has been associated with adverse outcomes, including heart failure and death. Minimizing RVP has been proposed as a therapeutic goal for a variety of pacing devices and indications.Objective. Quantify survival according to frequency of RVP in veterans with pacemakers.Methods. We analyzed electrograms from transtelephonic monitoring of veterans implanted with pacemakers between 1995 and 2005 followed by the Eastern Pacemaker Surveillance Center. We compared all cause mortality and time to death between patients with less than 20% and more than 80% RVP.Results. Analysis was limited to the 7198 patients with at least six trans-telephonic monitoring records (mean = 21). Average follow-up was 5.3 years. Average age at pacemaker implant was significantly lower among veterans with 20% RVP (67 years versus 72 years; ). An equal proportion of deaths during follow-up were noted for each group: 126/565 patients (22%) with 20% RVP and 1113/4968 patients (22%) with 80% RVP. However, average post-implant survival was 4.3 years with 20% RVP versus 4.7 years with 80% RVP ().Conclusions. Greater frequency (80%) of RVP was not associated with higher mortality in this population of veterans. Those veterans utilizing 20% RVP had a shortened adjusted survival rate ().

The long-term lead stability and echocardiographic outcomes of left bundle branch area pacing (LBBAP) are not fully understood. This study aimed to observe the mid-long-term clinical impact of LBBAP compared to right ventricular pacing (RVP). Consecutive bradycardia patients undergoing LBBAP or RVP were enrolled. Pacing and electrophysiological characteristics, echocardiographic measurements, and procedural complications were prospectively recorded at baseline and follow-up. LBBAP was successful in 376 of 406 patients (92.6%), while 313 patients received RVP. During a mean follow-up of 13.6 ± 7.8 months, LBBAP presented with similar pacing parameters and complications to RVP, except a significantly narrower paced QRS duration (115.7 ± 12.3 ms vs. 148.0 ± 18.0 ms, p < 0.001). In 228 patients with ventricular pacing burden >40%, LBBAP at last follow-up resulted in decreased left atrial diameter (LAD) (40.1 ± 8.5 mm vs. 38.5 ± 8.0 mm, p < 0.001) while RVP produced decreased left ventricular ejection fraction (62.7 ± 4.8% vs. 60.5 ± 6.9%, p < 0.001) when compared to baseline. After adjusting for age, the presence of atrial fibrillation, and other clinical factors, LBBAP was still associated with a decrease in LAD (−1.601, 95% CI −3.094–−0.109, p = 0.036). We conclude that LBBAP might result in more preserved echocardiographic outcomes than RVP.

Abstract Aims The aim of this study is to prospectively assess the feasibility and safety of left bundle branch pacing (LBBP) when compared with right ventricular pacing (RVP) during mid-long-term follow-up in a large cohort. Methods and results Patients (n = 554) indicated for pacemaker implantation were prospectively and consecutively enrolled and were non-randomized divided into LBBP group and RVP group. The levels of cTnT and N-terminal pro-B type natriuretic peptide were measured and compared within 2 days post-procedure between two groups. Implant characteristics, procedure-related complications, and clinical outcomes were also compared. Pacing thresholds, sensing, and impedance were assessed during procedure and follow-up. Left bundle branch pacing was feasible with a success rate of 94.8% with high incidence of LBB potential (89.9%), selective LBBP (57.8%), and left deviation of paced QRS axis (79.7%) with mean Sti-LVAT of 65.07 ± 8.58 ms. Paced QRS duration was significantly narrower in LBBP when compared with RVP (132.02 ± 7.93 vs. 177.68 ± 15.58 ms, P &lt; 0.0001) and the pacing parameters remained stable in two groups during 18 months follow-up. cTnT elevation was more significant in LBBP when compared with RVP within 2 days post-procedure (baseline: 0.03 ± 0.03 vs. 0.02 ± 0.03 ng/mL, P = 0.002; 1 day post-procedure: 0.13 ± 0.09 vs. 0.04 ± 0.03 ng/mL, P &lt; 0.001; 2 days post-procedure: 0.10 ± 0.08 vs. 0.03 ± 0.08 ng/mL, P &lt; 0.001). The complications and cardiac outcomes were not significantly different between two groups. Conclusion Left bundle branch pacing was feasible in bradycardia patients associated with stable pacing parameters during 18 months follow-up. Paced QRS duration was significantly narrower than that of RVP. Though cTnT elevation was more significant in LBBP within 2 days post-procedure, the complications, and cardiac outcomes were not significantly different between two groups.

Abstract Background and Aims Perivascular fat attenuation index (FAI) of coronary artery represents the degree of coronary inflammation. High coronary artery FAI in computed tomography angiography (CTA) is associated with increased all-cause and cardiac mortality in general population. However, the ability of the perivascular FAI using coronary CTA to predict long term outcome in chronic kidney disease (CKD) patients is unknown. Method This is a single center retrospective study. We analyzed coronary FAIs on CTA for CKD including patients with end stage renal disease (ESRD). The patients with percutaneous coronary intervention or coronary artery bypass graft were excluded. Mapping and analysis of perivascular FAI were performed around proximal three major coronary arteries. We assessed the prognostic value of FAI of CTA for long-term mortality (data from the Korean National Statistical Office) with Cox regression models, adjusted for age, sex, dialysis vintage, and clinical parameters. Results Between January 2012 and June 2018, 268 CKD patients were included. Mean age of this cohort was 64.5 ± 12.0 years, and 132 (49.3%) participants were men. 109 (44.7%) participants has diabetic kidney disease, and 179 (66.4%) participants were on hemodialysis. Median follow-up after coronary CTA was 29.2 (15.1 − 46.3) months. During follow-up, there were 43 (20.6%) deaths. The optimum cut-off value of FAI around the left anterior descending artery (LAD) was ascertained as -65.5 Hounsfield unit. The high perivascular FAI around the LAD was significantly associated with higher adjusted risk of all-cause mortality (hazard ratio, 2.15; 95% CI, 1.07–4.32). In ESRD subgroup, the high perivascular FAI group also has higher adjusted risk of all-cause mortality compared to low perivascular FAI group (hazard ratio, 2.43; 95% CI, 1.16–5.09). Conclusion The perivascular FAI around LAD predicts the long-term mortality in patients with CKD. This could provide the chance of early primary intervention in CKD patients.

Abstract Background Elevated pre-procedural high-sensitivity troponin T (hs-TnT) levels predict adverse outcomes in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR). It is unknown whether elevated troponin levels still provide prognostic information during follow-up after successful TAVR. We evaluated the long-term implications of elevated hs-TnT levels found at 1-year post-TAVR. Methods and results The study included 349 patients who underwent TAVR for severe AS from 2010–2019 and for whom 1-year hs-TnT levels were available. Any required percutaneous coronary interventions were performed > 1 week before TAVR. The primary endpoint was survival time starting at 1-year post-TAVR. Optimal hs-TnT cutoff for stratifying risk, identified by ROC analysis, was 39.4 pg/mL. 292 patients had hs-TnT < 39.4 pg/mL (median 18.3 pg/mL) and 57 had hs-TnT ≥ 39.4 pg/mL (median 51.2 pg/mL). The high hs-TnT group had a higher median N-terminal pro-B-type natriuretic peptide (NT-proBNP) level, greater left ventricular (LV) mass, higher prevalence of severe diastolic dysfunction, LV ejection fraction < 35%, severe renal dysfunction, and more men compared with the low hs-TnT group. All-cause mortality during follow-up after TAVR was significantly higher among patients who had hs-TnT ≥ 39.4 pg/mL compared with those who did not (mortality rate at 2 years post-TAVR: 12.3% vs. 4.1%, p = 0.010). Multivariate analysis identified 1-year hs-TnT ≥ 39.4 pg/mL (hazard ratio 2.93, 95% CI 1.91–4.49, p < 0.001), NT-proBNP level > 300 pg/mL, male sex, an eGFR < 60 mL/min/1.73 m2 and chronic obstructive pulmonary disease as independent risk factors for long-term mortality after TAVR. Conclusions Elevated hs-TnT concentrations at 1-year after TAVR were associated with a higher long-term mortality. Graphic abstract
