A Novel Echocardiography Modality to Assess Left Ventricular Dyssynchrony

NCT01007981 | Withdrawn

• 1 other identifier: 1124400
• Study Type: observational
• Target: N/A
• Locations: 0 countries
• Sites: N/A

Brief Summary

The investigators hypothesize that the relation between mechanical and hemodynamic left ventricular dyssynchrony might better predict response to Cardiac Resynchronization Device(CRT) than currently existing echo indices.

Conditions

Heart Failure

Outcome Measures

Primary Outcomes (1)

• 4D echo is the best modality to measure systolic dyssynchrony index

  Two years

Study Arms (1)

CRT device

Patients with Cardiac Resynchronization Therapy(CRT) device implanted in the last 5 years will be studied by the new echo modality.Study doesn't involve acute device implantation.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Patients followed in cardiology clinic will be included.

You may qualify if:

• Cardiac Resynchronization Therapy(CRT) device implanted in the last 5 years.

You may not qualify if:

• Acute decompensated congestive heart failure.
• chronic permanent atrial fibrillation
