Improved estimation of left ventricular volume from electric field modeling

Journal of Electrical Bioimpedance, 2021
Volume measurement is beneficial in left ventricular assist device (LVAD) therapy to quantify patient demand. In principle, an LVAD could provide a platform that allows bioimpedance measurements inside the ventricle without requiring additional implants.

Invasive Assessment of Right Ventricular Dysfunction Predicts Periprocedural Outcomes in Patients Undergoing Unplanned Ventricular Tachycardia Ablation

Journal of Cardiovascular Electrophysiology, EarlyView.
Displays bar graphs showing outcome rates stratified by clinical and hemodynamic variables. Asterisks (*) denote statistically significant differences (p ≤ 0.05). “NS” indicates non‐significant comparisons. Percentages are shown above each bar. The top panel corresponds to acute kidney injury (blue bars), and the bottom panel corresponds to acute ...

Recent Developments in Ventricular Assist Device Therapy

Reviews in Cardiovascular Medicine
The evolution of left ventricular assist devices (LVADs) from large, pulsatile systems to compact, continuous-flow pumps has significantly improved implantation outcomes and patient mobility. Minimally invasive surgical techniques have emerged that offer

Impacts of Hemodynamic Support on Ventricular Arrhythmia Ablation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Data on the efficacy of hemodynamic support (HS) for protecting ventricular arrhythmia (VA) ablation in high‐risk heart failure (HF) patients with an impaired left ventricular function and its impact on mortality is limited. Objectives This study aimed to assess procedural efficacy, related complications, VA‐free survival, and ...

Ventricular Tachycardia Ablation in Structural Heart Disease With LVEF > 35%: Clinical Outcomes and Recurrence Patterns

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background In patients with structural heart disease (SHD) and moderately impaired left ventricular ejection fraction (LVEF > 35%), data on outcomes after ventricular tachycardia (VT) ablation remain limited. This analysis focuses on VT recurrence after ablation in patients presenting with sustained VT and LVEF > 35% within a secondary ...

Association Between Sleep Quality and Oxidative Stress in Postoperative Cardiovascular Patients—A Pilot Study

Journal of Sleep Research, EarlyView.
In 15 postoperative cardiac surgery patients, venous reactive oxygen species (ROS) measured by electron spin resonance (ESR) over 48 h showed no consistent circadian pattern. Higher ROS was associated with lower subjective sleep efficiency and more nocturnal awakenings, but not with other sleep measures.

Impact of ICD Presence in Patients With Left Ventricular Assist Devices for End‐Stage Heart Failure

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background The prognostic relevance of implantable cardioverter defibrillator (ICD) in patients with end‐stage heart failure (HF) with left ventricular assist device (LVAD) remains controversial. Objectives To evaluate the prognostic impact of ongoing use of ICD and associated complications in HF‐patients with LVAD‐implantation.

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

The Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.
