Diagnosis of atrial fibrillation in heart failure patients with implantable cardioverter defibrillator or cardiac resynchronisation therapy
CONCLUSIONS: Episodes of paroxysmal atrial fibrillation in patients with systolic heart failure and implanted cardioverter-defibrillator systems are quite common. The majority of the episodes recorded in the study were asymptomatic.PMID:34900037 | PMC:PMC8641502 | DOI:10.5114/aoms/114977

Regional contributions to left ventricular stroke volume determined by cardiac magnetic resonance imaging in cardiac resynchronization therapy
Cardiac resynchronization therapy (CRT) restores ventricular synchrony and induces left ventricular (LV) reverse remodeling in patients with heart failure (HF) and dyssynchrony. However, 30% of treated patient...

Multipoint left ventricular pacing effects on hemodynamic parameters and functional status: HUMVEE single-arm clinical trial (NCT03189368)
CONCLUSIONS: optimized MPP showed significant improvements on hemodynamic parameters and ventricular function, in heart failure patients over optimized CRT. The beneficial effect was more prominent in men and in those with rather reduced LVEF, consistent with findings suggesting a beneficial trend in VAC and CP with the more homogenous depolarization offered by optimized MPP.PMID:33677032 | DOI:10.1016/j.hjc.2021.02.012

Acute recoordination rather than functional hemodynamic improvement determines reverse remodelling by cardiac resynchronisation therapy
Conclusion: Long-term reverse remodelling after CRT is likely determined by (acute) recoordination rather than by acute hemodynamic improvements. Discoordination may therefore be a more important CRT-substrate that can be assessed and, acutely restored.

VVI pacing with normal QRS duration and ventricular function: MOST trial findings relevant to leadless pacemakers
ConclusionIn patients without reduced LVEF or prolonged QRSd who would be eligible for LP, DDDR, and VVIR pacing demonstrated similar rates of death, stroke or HF hospitalization; however, VVIR pacing significantly increased the risk of AF development.

The Usefulness and Limitations of Impedance Cardiography for Cardiac Resynchronization Therapy Device Optimization.
This study sought to assess the clinical utility of ICG in comparison with that of UCG for the optimization of CRT devices.Patients who underwent CRT device implantation were retrospectively analyzed. One week after implantation, optimization of AV delay (AVD) was performed in every patient with ICG (AVD-ICG) and UCG (AVD-UCG). VV delay (VVD) was then determined according to the optimal AVD using these two methods.Forty-two patients were enrolled. Average AVD-ICG was significantly shorter than AVD-UCG (128 ± 49 versus 146 ± 41 milliseconds, P = 0.018). Five patients (12%) had the same optimized AVD with two methods, and ...
