Bilateral remote ischemic conditioning in children: A two-center, double-blind, randomized controlled trial in young children undergoing cardiac surgery.

Objective: The study objective was to determine whether adequately delivered bilateral remote ischemic preconditioning is cardioprotective in young children undergoing surgery for 2 common congenital heart defects with or without cyanosis.

Methods: We performed a prospective, double-blind, randomized controlled trial at 2 centers in the United Kingdom. Children aged 3 to 36 months undergoing tetralogy of Fallot repair or ventricular septal defect closure were randomized 1:1 to receive bilateral preconditioning or sham intervention.

Transapical approach to optimize left ventricular resynchronization in patients with dilated cardiomyopathy.

An alternative to coronary sinus implantation for a left ventricular pacing lead is frequently needed for cardiac resynchronization therapy. We have developed a transapical approach to implant an endocardial pacing lead that will reach the most delayed segment of the left ventricle. This method is easily combined with other transapical heart surgeries.

Long-term cerebral thromboembolic complications of transapical endocardial resynchronization therapy.

Purpose: Cardiac resynchronization therapy (CRT) is an established therapeutic option in selected heart failure patients (pts). However, the transvenous left ventricular (LV) lead implantation remains ineffectual in a considerable number of pts. Transapical LV (TALV) lead implantation is an alternative minimally invasive, surgical, endocardial implantation technique.

Alternative techniques for left ventricular pacing in cardiac resynchronization therapy.

Cardiac resynchronization therapy (CRT) is an important treatment modality for a well-defined subgroup of heart failure patients. Coronary sinus (CS) lead placement is the first-line clinical approach but the insertion is unsuccessful in about 5-10% of the patients. In recent years, the number of CRT recipients and the considerable need for left ventricular (LV) lead revisions increased enormously.
