ABSTRACT Background Electrographic flow (EGF) mapping allows for the visualization of global atrial wavefront propagations. One mechanism initiation and maintenance fibrillation (AF) is stimulation from EGF‐identified focal sources that serve as driver sites fibrillatory conduction. consistency (EGFC) further quantifies concordance observed patterns, indicating a healthier substrate shows more organized propagation higher EGFC. Freedom AF (FFAF) recurrence has accordingly been shown to be in...
Abstract Background Sarcomere gene mutations is hypertrophic cardiomyopathy (HCM) can have prognostic value and role in risk assessment, according to numerous studies. In our previous investigations, we confirmed that echocardiographic parameters of left ventricular (LV) myocardial work (MW) derived from the non-invasive pressure-strain curve were reduced patients with HCM, especially case clinical features advanced disease. The aim present was investigate MW genotyped HCM patients. Patients...
Abstract Introduction Mavacamten is a selective, allosteric and reversible cardiac myosin inhibitor indicated for the treatment of symptomatic (NYHA II-III class) adult patients with obstructive [≥ 50 mmHg resting or provokable left ventricular outflow tract (LVOT) peak gradient] hypertrophic cardiomyopathy (HOCM). Patients Methods Ten HOCM [5 men (50%), mean age: 57±11 years) were treated mavacamten. In 9 provoked gradient was >100 Hgmm. addition to recording main demographic,...
Abstract Introduction Mavacamten is a novel therapy for hypertrophic obstructive cardiomyopathy. Left ventricular (LV) ejection fraction (EF) has been used monitoring of left systolic function during therapy. Currently there limited data on advanced functional parameters based speckle tracking strain values, such as global longitudinal (GLS) , myocardial work (MW) or 3D echocardiography. MW an emerging method which incorporates pressure and provides multiple LV pressure-strain loop. This...
Abstract Funding Acknowledgements Type of funding sources: None. Background Electrographic flow (EGF) mapping detects and quantifies patterns electrical wavefront propagation in the atrial myocardium from basket catheter recordings. However, no single can map entire endocardial surface simultaneously. Creating panoramic maps whole atrium may be possible by reconstructing multiple positions obtained within a few minutes each other. Purpose Present method 3D reconstruction EGF generated...
Abstract Funding Acknowledgements Type of funding sources: None. Background Anatomical variations and characteristics the left atrium (LA) may have a previously undescribed effect on source locations in atrial fibrillation (AF). Electrographic flow (EGF) mapping is novel method used to estimate cardiac action potential atria that can detect AF sources patients with persistent AF. The EGF technology offers revolutionary possibility for AF, however, it not commercially available yet. Purpose...
