Randomized Controlled Trial Comparative StudyComparison of the efficacy of two surgical alternatives for cardiac resynchronization therapy: trans-apical versus epicardial left ventricular pacing.
Epicardial pacing lead implantation is the currently preferred surgical alternative for left ventricular (LV) lead placement. For endocardial LV pacing, we developed a fundamentally new surgical method. The trans-apical lead implantation is a minimally invasive technique that provides access to any LV segments. The aim of this prospective randomized study was to compare the outcome of patients undergoing either trans-apical endocardial or epicardial LV pacing. ⋯ Our data suggest that trans-apical endocardial LV lead implantation is an alternative to epicardial LV pacing.

Case ReportsDeath and near death from cardiac arrest during the Boston Marathon.
The Boston Marathon has been run for 115 years during which there were three sudden cardiac arrests. The most recent was a near death avoided by rapid cardiopulmonary resuscitation (CPR) and defibrillation. Awareness of the dangers of participating in a marathon, the risk factors associated with sudden death during competition, and the life-saving importance of rapid CPR and defibrillation are essential for participants and event organizers. ⋯ Prevention or reduction of life-threatening cardiac incidents during marathon races might be achieved if participants of advanced age or with a history of coronary artery disease seek medical clearance prior to entering an event. Those with coronary risk factors should have a discussion with their physician. Availability of trained personnel and defibrillators are important considerations in marathon planning.
