Author

Abstract

Left atrial appendage occlusion (LAAO) has emerged as a highly effective alternative to oral anticoagulation for stroke prevention in patients with non-valvular atrial fibrillation. Precise pre-procedural planning and meticulous post-procedural follow-up are essential for achieving successful LAAO outcomes. This review explores the latest advancements in three-dimensional (3D) transoesophageal echocardiography (TOE) and computed tomography (CT) imaging modalities, which have considerably improved the planning, intra-procedural guidance, and follow-up processes for LAAO interventions. Innovations in 3D TOE and CT imaging have transformed the approach to LAAO by providing a more detailed and accurate assessment of the left atrial appendage, enabling clinicians to acquire comprehensive anatomical and morphological information, crucial for optimising device selection and positioning, thus reducing the risk of complications and enhancing the overall safety and efficacy of the procedure. Post-procedurally, CT and TOE imaging are invaluable in the monitoring of patients, ensuring that the device is correctly positioned and functioning as intended. Early detection of any complications (e.g., device-related thrombus and peri-device leaks) can help to risk-stratify patient at increased risk of stroke and initiate timely interventions, thereby improving long-term outcomes for patients.

Abstract

Aims: The randomized, double‐blind, placebo‐controlled HOPE‐HF trial assessed the benefit of atrio‐ventricular (AV) delay optimization delivered using His bundle pacing. It recruited patients with left ventricular ejection fraction ≤40%, PR interval ≥200 ms, and baseline QRS ≤140 ms or right bundle branch block. Overall, there was no significant increase in peak oxygen uptake (VO2max) but there was significant improvement in heart failure specific quality of life. In this pre‐specified secondary analysis, we evaluated the impact of baseline PR interval, echocardiographic E‐A fusion, and the magnitude of acute high‐precision haemodynamic response to pacing, on outcomes. Methods and results: All 167 randomized participants underwent measurement of PR interval, acute haemodynamic response at optimized AV delay, and assessment of presence of E‐A fusion. We tested the impact of these baseline parameters using a Bayesian ordinal model on VO2max, quality of life and activity measures. There was strong evidence of a beneficial interaction between the baseline acute haemodynamic response and the blinded benefit of pacing for VO2 (Pr 99.9%), Minnesota Living With Heart Failure (MLWHF) (Pr 99.8%), MLWHF physical limitation score (Pr 98.9%), EQ‐5D visual analogue scale (Pr 99.6%), and exercise time (Pr 99.4%). The baseline PR interval and the presence of baseline E‐A fusion did not have this reliable ability to predict the clinical benefit of pacing over placebo across multiple endpoints. Conclusions: In the HOPE‐HF trial, the acute haemodynamic response to pacing reliably identified patients who obtained clinical benefit. Patients with a long PR interval (≥200 ms) and left ventricular impairment who obtained acute haemodynamic improvement with AV‐optimized His bundle pacing were likely to obtain clinical benefit, consistent across multiple endpoints. Importantly, this gradation can be reliably tested for before randomization, but does require high‐precision AV‐optimized haemodynamic assessment to be performed. [ABSTRACT FROM AUTHOR]

Abstract

The understanding of the underlying mechanisms of the persistence of atrial fibrillation remains poor. Key to this is the relationship between structure - myocardial architecture, and function - electrical activity, and how these can be measured, interpreted and correlated clinically. We sought to address the hypothesis that the local electrogram morphology is determined by local atrial myocardial activation patterns, which are in turn determined by local atrial myocardial architecture. In addressing this hypothesis, we utilised improved techniques of atrial segmentation and detection of wall enhancements to more accurately delineate underlying de novo atrial myocardial fibrosis, with late-gadolinium enhanced cardiac magnetic resonance imaging (LGE- CMRI). Here, we demonstrated a predilection of native structural remodelling on the posterior left atrial wall. The electrophysiological changes underlying late-gadolinium enhancements were interrogated with high-density electroanatomic 3D mapping using a Kernel as a unit of measure, in the varying rhythms of AF, sinus and pacing, with drop in tissue voltages and conduction velocities in regions of fibrosis, but counter-intuitively, a higher extent of electrogram fractionation in healthy myocardium. We observed the rate and wavefront-activation dependency of voltage, emphasizing the importance of voltage maps being interpreted in the context of its rhythm. We have also described a novel technique of AF voltage mapping, with the metric of mean AF voltage sampled over 8 secs correlating well with LGE-CMRI defined fibrosis, and surprisingly better than that of sinus rhythm voltage suggesting that this metric may be more representative of the underlying atrial substrate. Lastly, reverse translational cell monolayer experiments in novel co-cultured neonatal ventricular rat myocytes and fibroblasts were carried out to corroborate clinical in vivo observations under the control of the basic science laboratory. These emphasized the contributions of the structural and functional changes to electrogram morphology (voltage and fractionation). The contact electrogram is the result of a complex dynamic functional electrophysiology, and its interactions with the underlying atrial myocardium. This increased understanding of structure and function (electroarchitecture) provides mechanistic insights essential if we are to progress beyond the current empiricism of catheter ablation strategies of persistent AF.

Abstract

Introduction: Patients with hypertrophic cardiomyopathy (HCM) are at risk for lethal ventricular arrhythmia, but the electrophysiological substrate behind this is not well-understood. We used non-invasive electrocardiographic imaging to characterize patients with HCM, including cardiac arrest survivors. Methods: HCM patients surviving ventricular fibrillation or hemodynamically unstable ventricular tachycardia (n = 17) were compared to HCM patients without a personal history of potentially lethal arrhythmia (n = 20) and a pooled control group with structurally normal hearts. Subjects underwent exercise testing by non-invasive electrocardiographic imaging to estimate epicardial electrophysiology. Results: Visual inspection of reconstructed epicardial HCM maps revealed isolated patches of late activation time (AT), prolonged activation-recovery intervals (ARIs), as well as reversal of apico-basal trends in T-wave inversion and ARI compared to controls (p < 0.005 for all). AT and ARI were compared between groups. The pooled HCM group had longer mean AT (60.1 ms vs. 52.2 ms, p < 0.001), activation dispersion (55.2 ms vs. 48.6 ms, p = 0.026), and mean ARI (227 ms vs. 217 ms, p = 0.016) than structurally normal heart controls. HCM ventricular arrhythmia survivors could be differentiated from HCM patients without a personal history of life-threatening arrhythmia by longer mean AT (63.2 ms vs. 57.4 ms, p = 0.007), steeper activation gradients (0.45 ms/mm vs. 0.36 ms/mm, p = 0.011), and longer mean ARI (234.0 ms vs. 221.4 ms, p = 0.026). A logistic regression model including whole heart mean activation time and activation recovery interval could identify ventricular arrhythmia survivors from the HCM cohort, producing a C statistic of 0.76 (95% confidence interval 0.72-0.81), with an optimal sensitivity of 78.6% and a specificity of 79.8%. Discussion: The HCM epicardial electrotype is characterized by delayed, dispersed conduction and prolonged, dispersed activation-recovery intervals. Combination of electrophysiologic measures with logistic regression can improve differentiation over single variables. Future studies could test such models prospectively for risk stratification of sudden death due to HCM. [ABSTRACT FROM AUTHOR]

Abstract

RETRO‐mapping was developed to automate activation mapping of atrial fibrillation (AF). We used the algorithm to study the effect of pulmonary vein isolation (PVI) on the frequency of focal, planar, and colliding wavefronts in persistent AF. An AFocusII catheter was placed on the left atrial endocardium to record 3 s of AF at six sites pre and post‐PVI in patients undergoing wide circumferential PVI for persistent AF. RETRO‐mapping analyzed each segment in 2 ms time windows for evidence of focal, planar, and colliding waveforms and the automated categorizations manually validated. Ten patients were recruited. A total of 360 s of data in 120 segments of 3 s from 60 left atrial locations were analyzed. RETRO‐map was highly effective at identifying focal waves and collisions during AF. PVI significantly reduced collision frequency but not focal and planar activation frequency. However, there was a significant reduction in the dispersion of activation directions. Larger studies may help determine factors associated with successful clinical outcome. [ABSTRACT FROM AUTHOR]
