Why the study?
Does apical left ventricular lead position affect clinical outcomes in patients receiving cardiac resynchronization therapy?
Does apical left ventricular lead position affect clinical outcomes in patients receiving cardiac resynchronization therapy?
Apical positioning of left ventricular leads in cardiac resynchronization therapy is associated with unfavorable outcomes and should be avoided.
Apical LV lead placement may worsen CRT outcomes; leaves open whether avoiding it improves prognosis in randomized trials.
LV leads positioned in the apical region were associated with an unfavorable outcome, suggesting that this lead location should be avoided in cardiac resynchronization therapy. Clinical Trial Registration- URL: http://clinicaltrials.gov. Unique identifier: NCT00180271.
