Case 4
A 78-year-old male with permanent atrial fibrillation on warfarin and
longstanding dilated cardiomyopathy with depressed ejection fraction
despite optimal medical therapy was referred for Biventricular upgrade.
However, a previous attempt to place a coronary sinus lead was
unsuccessful 2 months prior. After discussion, the decision was made to
attempt LV endocardial lead placement. The procedure was well tolerated
without complications. Follow-up has been limited since the procedure
with no repeat EF testing or assessment of functional status documented.
