Valve Implantation

Transcatheter aortic valve implantation (TAVI) is an effective intervention for severe aortic stenosis in patients at intermediate or high surgical risk, but damage to the native conduction system such as left bundle branch block (LBBB) may offset its benefits. New onset LBBB is associated with a higher risk of cardiovascular morbidity and mortality. His-bundle pacing (HBP) may be useful to treat TAVI-induced LBBB but has yet to be reported. We present the case of a 76-year-old man with severe symptomatic aortic stenosis treated with TAVI. His preoperative electrocardiogram showed sinus rhythm with a narrow QRS complex. Insertion of a CoreValve Evolut R transcatheter aortic valve was uneventful apart from the development of LBBB with a long PR interval. A dual-lead DDD pacemaker was implanted via the left cephalic vein on the following day. HV was mildly prolonged at 60 ms. Capture of the proximal His restored AV synchrony without correction of LBBB. Repositioning of the lead with capture of the left bundle branch enabled complete ventricular resynchronisation with a single lead. Our case demonstrates that LBBB in the setting of TAVI may be corrected by HBP.

Abstract Background Left bundle branch block (LBBB) occurs frequently after transcatheter aortic valve replacement (TAVR) and is associated with increased risk of permanent pacemaker implantation, heart failure hospitalization and sudden cardiac death. This pilot study explored the feasibility of TAVR-induced LBBB correction with His bundle pacing (HBP). Methods Patients with TAVR -induced LBBB and postoperative need for permanent pacemaker implant were planned for electrophysiology study and HBP. Patients with persistent high degree AV-block were excluded. HBP was performed using the Select Secure pacing lead, delivered through a fixed curve or a deflectable sheath. Successful HBP was defined as correction of LBBB by selective or non-selective HBP with LBBB correction thresholds less than 3.5V at 1.0ms at implant. Results The study enrolled 6 patients (mean age 85±2.5 years, 50% male). Mean QRS duration was 152±10ms, PR-interval 212±12ms AH-interval 166±16ms and HV-interval 62±12ms. Successful HBP was achieved in 5/6 (83%) patients. Mean QRS duration decreased from 153±11ms to 88±14ms (p=0.002). At implantation, mean threshold for LBBB correction was 1.6±1.0V (unipolar) and 2.2±1.3V (bipolar) at 1.0ms. Periprocedural, two complete AV-blocks occurred, both spontaneously resolved by the end of the procedure. Thresholds remained stable at 1 month follow up: 1.8±1.0V (unipolar) and 2.3±1.5V (bipolar) at 1.0ms. Figure 1 Conclusion Permanent His bundle pacing can safely correct TAVR-induced LBBB in the majority of patients. Further studies are needed to assess potential benefits of His bundle pacing over conventional right ventricular pacing in this population.

ObjectivesHis bundle pacing (HBP) can potentially correct left bundle branch block (LBBB). We aimed to assess the efficacy of HBP to correct LBBB and long-term clinical outcomes with HBP in patients with heart failure (HF).MethodsThis is an observational study of patients with HF with typical LBBB who were indicated for pacing therapy and were consecutively enrolled from one centre. Permanent HBP leads were implanted if the LBBB correction threshold was <3.5V/0.5 ms or 3.0 V/1.0 ms. Pacing parameters, left ventricular ejection fraction (LVEF), left ventricular end-systolic volume (LVESV) and New York Heart Association (NYHA) Class were assessed during follow-up.ResultsIn 74 enrolled patients (69.6±9.2 years and 43 men), LBBB correction was acutely achieved in 72 (97.3%) patients, and 56 (75.7%) patients received permanent HBP (pHBP) while 18 patients did not receive permanent HBP (non-permanent HBP), due to no LBBB correction (n=2), high LBBB correction thresholds (n=10) and fixation failure (n=6). The median follow-up period of pHBP was 37.1 (range 15.0–48.7) months. Thirty patients with pHBP had completed 3-year follow-up, with LVEF increased from baseline 32.4±8.9% to 55.9±10.7% (p<0.001), LVESV decreased from a baseline of 137.9±64.1 mL to 52.4±32.6 mL (p<0.001) and NYHA Class improvement from baseline 2.73±0.58 to 1.03±0.18 (p<0.001). LBBB correction threshold remained stable with acute threshold of 2.13±1.19 V/0.5 ms to 2.29±0.92 V/0.5 ms at 3-year follow-up (p>0.05).ConclusionspHBP improved LVEF, LVESV and NYHA Class in patients with HF with typical LBBB.

The Right

A 61-year-old woman was referred to our institution for evaluation of severe nonischemic dilated cardiomyopathy and left bundle branch block (LBBB). After permanent His bundle pacing, the LBBB was immediately corrected; however, the right bundle branch was injured during the procedure. Subsequent recovery of the right bundle branch block and normalization of heart function were observed during follow-up. This case indicates that LBBB might result in the development of nonischemic cardiomyopathy and emphasizes the necessity of a temporary pacemaker during His bundle pacing for patients with LBBB.
