Pilot Study Using Echocardiography to Evaluate Patients With Heart Failure and Dyssynchrony Who Have a CRT-D Device
Study Details
Study Description
Brief Summary
Out of all the patients that receive a CRT-D ( a dual chamber pacemaker with defibrillator ) for cardiac resynchronization therapy there is approximately one-third that do not respond. We believe that by using a simple technique that includes routine echocardiography that are normally performed in these patients could help us better understand how to program their device to reach better optimization.

Eligibility Criteria
Criteria
Inclusion Criteria:
-
Adults age 18-110 years
-
Must have a CRT-D (A biventricular pacemaker with defibrillator)
-
Last optimization of their device (CRT-D) must not have been done in the past 3 months
-
Must be optimal heart failure medical regimen. This includes target dose of beta-blocker and angiotensin converting enzyme inhibitor (ACE-I) (or equivalent; i.e angiotensin receptor blocker (ARB); or balanced preload and afterload reducers with hydralazine and nitrates.)
Exclusion Criteria:
-
Less than 18 years of age or greater than 110 years old.
-
Does not have a CRT-D
-
Optimization of their device has occurred in the past 3 months
-
Not on optimal medical therapy for heart failure as listed in the inclusion criteria.
