Baseline right ventricular (RV) function potentially determines the response to Cardiac Resynchronization Therapy (CRT) but is not included in the current selection criteria. In this meta-analysis, we examined the value of echocardiographic indices of RV function as potential predictors of CRT outcomes in patients with standard indications for CRT. Baseline tricuspid annular plane systolic excursion was consistently higher in CRT responders, and this association appears independent of age, sex, ischemic etiology of heart failure, and baseline left ventricular ejection fraction. This proof-of-concept meta-analysis of observational data may justify a more detailed assessment of RV function as an additional component in the selection process of CRT candidates.

Severe obesity is closely associated with an increased risk of comorbidities and alterations in cardiac structure and function. The primary objective of this study was to investigate cardiovascular (CV) risk factors and ventricular remodeling in individuals from an obese population eligible for bariatric surgery. The secondary objective was to evaluate changes in anthropometric, clinical laboratory, and echocardiographic measurements 12 weeks after surgery compared to baseline values.

Recently published data suggested significantly lower pacing-induced cardiomyopathy (PICM) incidence with conduction system pacing (CSP). Because most data evaluated only the impact on the left ventricle, this study aimed to assess changes in echocardiographic parameters of morphology and function for all heart chambers in patients with baseline preserved and mid-range LVEF over a medium-term follow-up period after CSP. A total of 128 consecutive patients with LVEF > 40% and successful CSP for bradyarrhythmic indication were prospectively enrolled.

Aims: Patients with atrial fibrillation (AF) are thought to have an attenuated response to adenosine during vasodilator stress testing. We sought to investigate the haemodynamic and hyperaemic effects of adenosine in patients with AF undergoing adenosine-stress cardiovascular magnetic resonance (CMR) assessment.
Methods And Results: We retrospectively examined 318 patients referred for clinical adenosine-stress CMR (AF = 158, sinus rhythm [SR] = 160).
Comparison of Alcohol Septal Ablation with Mavacamten in Obstructive Hypertrophic Cardiomyopathy.

Background: Obstructive hypertrophic cardiomyopathy (HCM) is associated with significant morbidity due to left ventricular outflow tract (LVOT) obstruction. While alcohol septal ablation (ASA) is an established interventional treatment, mavacamten, a novel cardiac myosin inhibitor, has emerged as a non-invasive pharmacological alternative. Understanding the comparative efficacy of these two treatments is important for optimizing patient care.
