Long-term outcomes of His bundle pacing in patients with heart failure with left bundle branch block

Heart, 2018
Objectives His 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).

Impact of Net Atrioventricular Compliance on Mitral Valve Area Assessment—A Perspective Considering Three-Dimensional Mitral Valve Area by Transesophageal Echocardiography

Diagnostics
Background: Net atrioventricular compliance (Cn) can affect the accuracy of mitral valve area (MVA) assessment. We assessed how different methods of MVA assessment are affected by Cn, and if patients with abnormal Cn may be identified by clinical and/or ...

Prognostic Value of the Global Left Ventricular Contractility Index in Patients with Severe Mitral Regurgitation and Preserved Left Ventricular Ejection Fraction

Journal of Cardiovascular Development and Disease
Introduction: Assessment of left ventricular (LV) systolic function is important in valvular heart disease. The global LV contractility index, dσ*/dtmax, is load-independent and has been reported to be associated with clinical outcomes in heart failure ...
