    Bachmann's bundle
    Opis:
    Background: Bachmann’s bundle plays a crucial role in the physiology of interatrial signal conduction. In the 1970s, Bayes de Luna introduced the definition of interatrial blocks (IABs), which negatively influence atrioventricular (AV) synchrony and left atrial (LA) activation. We aimed to assess the potential of LA strain technology in evaluating the mechanics of LA in patients with correct conduction and IABs. Additionally, we measured the parameters of regurgitation in pulmonary veins (PV), which depend on the type of interatrial conduction. Material and methods: The study group comprised 51 patients (26M, 25F) with symptomatic COVID-19 and sinus rhythm. Our study analyzed their medical history, electrocardiography (ECG) and echocardiography, including the LA strain parameters. Results: Global peak atrial longitudinal strain (PALS) depended on P wave duration, LA volume, left ventricular ejection fraction (LV EF) and inferior pulmonary veins (PV) regurgitation parameters. Global peak atrial contractile strain (PACS) statistically depends on the LV EF, LA volume and the P wave morphology. Conclusions: The presence of IABs negatively influences PACS and PALS. Examining LA strain is complementary to accurate ECG, which may be helpful in everyday clinical practice, particularly in diagnosing heart failure with preserved ejection fraction (HFpEF) and as a predictor of new episodes of atrial fibrillation (AF).

    His bundle pacing
    Opis:
    Background: Heart failure [HF] constitutes a complex clinical entity and often coexists with atrial fibrillation [AF]. There is scarcity of evidence-based therapies for those with ejection fraction [EF] ≥ 40%. Effect of regularization of ventricular response in patients with HF with EF ≥ 40% and concomitant atrial fibrillation is unknown. Material and methods: This was a retrospective case-series study. 14 patients with symptomatic HF with EF ≥ 40% and permanent atrial fibrillation who had undergone pHBP were identified and enrolled. For 9 patients pHBP was a primary strategy, for the remaining patients it was an upgrade from right ventricular lead. All patients underwent follow-up visit 3 months after the procedure. Results: NYHA class was significantly reduced (mean 2.5 vs. 1.0, p-value < 0.001). Left ventricular ejection fraction significantly increased mean increase 8.5%, 95% CI 7.7–9.2, p < 0.001) Similarly, significant decrease in left ventricular end diastolic diameter was observed (mean decrease 5.4 mm, 95% CI 5.0–5.8 mm, p < 0.001). The degree of mitral regurgitation after three months was lower (mean grade 2.4 vs. 1.2, p < 0.001). At follow-up prescribed doses of beta blocker were higher (mean metoprolol equivalent dose rose by 69.6 mg). Conclusions: Permanent His bundle pacing might be beneficial in the setting of permanent AF and HF with EF ≥ 40%.
