Introduction: Right ventricular (RV) pacing can impair left ventricular function and cause heart failure, known as pacing-induced cardiomyopathy (PICM). Upgrade to cardiac resynchronization (CRT) is its usual treatment; recently left bundle branch area pacing (LBBAP) has emerged as a potential alternative. Deep septal pacing (DSP), a simplified alternative to LBBAP, is still able to achieve narrower paced QRS than during conventional RV pacing.

Computed tomography (CT) has excellent spatial resolution and allows a clear distinction between myocardium and fat; thus, it has great potential for the evaluation of myocardial scar in ARVC. The objective of this study is to evaluate the feasibility, and the diagnostic and prognostic value of semi-automated quantification of right ventricular (RV) fat replacement from CT images.

- The study aimed to investigate the occurrence and outcomes of significant tricuspid valve regurgitation (TRI) following transvenous lead extraction (TLE) using mechanical rotational sheaths in patients with previously implanted leads.
- Out of 158 patients monitored, 5.7% experienced significant TRI post-extraction linked to prolonged lead implantation, tricuspid valve damage, and reasons for extraction like infection.
- Notably, severe TRI was identified as an independent mortality risk factor, emphasizing the need for physicians to closely observe patients for this complication during the TLE procedure.
Background: ADAS-3D software elaborates cardiac magnetic resonance (CMR) images to obtain a quantitative evaluation of dense scar and border zone (BZ), including BZ channels, which can be useful for ventricular tachycardia ablation and risk stratification. However, most prior reports with ADAS-3D used flexible thresholds (60% ± 5% and 40% ± 5% of maximum pixel signal intensity) to define dense scar and BZ. The impact of such variations of the threshold values on the measurements obtained with ADAS-3D is unknown.

- LVADs are becoming more popular for treating advanced heart failure, and this study examines patients who had a subcutaneous ICD prior to LVAD surgery.
- The research involved 30 patients with a median age of 45, focusing on the performance and complications of using both devices together, with follow-up averaging 7 months.
- Results showed high compatibility but highlighted issues like electromagnetic interference affecting device sensing, leading to inappropriate shocks in some patients; careful monitoring for these problems is essential.
