E‐CAD: Electroactive Polymer‐Based Cardiac Assist Device with Low Power Consumption

Advanced Intelligent Systems, EarlyView.
Conventional cardiac assist devices often require high power, involve direct blood contact, and risk driveline infections. This work presents a soft electroactive polymer‐based system that compresses the heart externally while consuming <0.3 W. With no blood contact, a 0.3 mm driveline, and a compact design, E‐CAD demonstrates enhanced output and ...

Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

The Anatomical Record, EarlyView.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.

The First‐in‐Man Technique of Drug Eluting and Perfusion Therapy for Left Main Coronary Artery Disease

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Treating ostial left circumflex artery (LCx) lesions in percutaneous coronary intervention (PCI) for left main disease (LMD) remains a challenge. Despite recent recommendations for the use of drug‐coated balloon (DCB) in this lesion, there are concerns about crossover‐stenting from the left main trunk (LMT) to the left anterior ...

Ventricular fibrillation caused by massive right coronary air embolism: a case report

The Egyptian Heart Journal
Background Coronary air embolism is a rare but severe complication of coronary interventions. Case presentation We present a case of a massive air embolism in the right coronary artery during percutaneous coronary intervention, resulting in ventricular ...

Long‐Term Follow‐Up After Direct‐Flow Transcatheter Aortic Valve Implantation: A Single Center Experience

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Aims Valve degeneration after DirectFlow implantation poses a challenge for valve‐in‐valve procedures due to its fragile polymeric structure and embolization risk. This study analyzes long‐term follow‐up of patients who underwent TAVI with DF to understand valve degeneration tendencies.

Prophylactic IABP Use in Protected PCI Reduces Infarction Size and Leads to More Complete Revascularization in Comparison to Rescue IAPB Use

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background There is little data questioning the timing of intra‐aortic balloon pump (IABP) implantation in non‐cardiogenic shock patients undergoing high‐risk percutaneous procedures. Aims We compared prophylactic IABP (P‐IABP) implantation to an emergent, unplanned rescue use (R‐IABP) in high‐risk PCI. Methods Among 300 IAPB patients who were

Early Stroke Volume Variation After Transcatheter or Surgical Aortic Valve Replacement Predicts Clinical Outcomes in Low‐Flow Aortic Stenosis

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Little is known about stroke volume index (SVi) change and its prognostic implication in patients with low‐flow aortic stenosis (AS) undergoing aortic valve replacement (AVR) and conflicting results are present in literature. The aim of this study was to evaluate the postoperative change in SVi and its impact on outcomes in patients

The Relationship between Thrombolysis in Myocardial Infarction Frame Count and Fractional Flow Reserve in Patients with Moderate Coronary Stenosis Undergoing Coronary Angiography

پزشکی بالینی ابن سینا, 2017
Background and Objective: Thrombolysis in myocardial infarction (TIMI) frame count (TFC) is an objective and quantitative index of coronary flow, and myocardial fractional flow reserve (FFR) is a lesion-specific index for epicardial coronary stenosis ...

Fractional flow reserve is a useful reference standard for myocardial perfusion studies with limitations [PDF]

European Heart Journal - Cardiovascular Imaging, 2014
Plein and Motwani1, in their editorial comment on a study by Ebersberger et al. 2 in the journal, state that because the ischaemia threshold of fractional flow reserve (FFR) was initially ‘validated’ in patients with unequivocal stress-induced ischaemia by stress SPECT/echocardiogram (ECHO),3 subsequent studies using FFR as a reference standard to ...

A Road Less Traveled: Successful Alcohol Septal Ablation via an Aberrant Septal Coronary Artery in Hypertrophic Obstructive Cardiomyopathy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Alcohol septal ablation (ASA) is a minimally invasive treatment option for patients with hypertrophic obstructive cardiomyopathy (HOCM) who remain symptomatic despite medical treatment and are either poor surgical candidates or prefer a less invasive approach.
