Improving ventricular pacing in adults and children : to treat or to avoid dyssynchrony-induced cardiac failure [PDF]

, 2012
This research shows that even patients with mild cardiac failure induced by dyssynchrony (a badly coordinated contraction of the heart) can benefit from ‘resynchronizing’ both heart chambers by artificial stimulation of both heart chambers.

Artificial septal, apical and bifocal cardiac pacing: comparative study using transesophageal echocardiography intraoperative

, 2022
INTRODUÇÃO: O tratamento da bradicardia severa com a estimulação cardíaca convencional, apical do ventrículo direito, tem se mostrado eficaz para a correção da frequência cardíaca. Apesar de necessária, esta estimulação produz um QRS largo com morfologia

Electroactive polymer scaffolds for cardiac tissue engineering [PDF]

, 2015
By-pass surgery and heart transplantation are traditionally used to restore the heart’s functionality after a myocardial Infarction (MI or heart attack) that results in scar tissue formation and impaired cardiac function.

Complete restoration of multiple dystrophin isoforms in genetically corrected Duchenne muscular dystrophy patient–derived cardiomyocytes

Molecular Therapy: Methods & Clinical Development, 2014
Duchenne muscular dystrophy (DMD)–associated cardiac diseases are emerging as a major cause of morbidity and mortality in DMD patients, and many therapies for treatment of skeletal muscle failed to improve cardiac function. The reprogramming of patients'

Identifying transcription factors controlling the basal expression of human MRP4 highlights a substantial role for Sp1

FEBS Open Bio, EarlyView.
The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.

Stellate ganglion stimulation and performance of dog heart-lung preparation

, 1961
Observations were made on the changes in cardiac function in the dog heart-lung preparation, brought about by stimulation of the left stellate ganglion, and were compared with observations obtained when the heart was driven by an artificial pacemaker ...

Multimodal Soft Surgical Robots Enabled by Eco‐Degradable, Sterilizable Polymers and Transient Electronics

Advanced Functional Materials, EarlyView.
A compostable PGS soft surgical robot with interchangeable modules integrates transient Mo tactile and Si thermal sensors for dual feedback. The device preserves its function after clinical‐grade sterilization, demonstrates stable actuation and cardiac tissue grasping with real‐time in vivo pulsatile monitoring, and biodegrades post‐use with soil‐safe,

ECG-triggered muscular counterpulsation for treatment of low cardiac output

, 2007
BACKGROUND: Skeletal muscular counterpulsation (MCP) has been used as a new noninvasive technique for treatment of low cardiac output. The MCP method is based on ECG-triggered skeletal muscle stimulation.
