Why the study?
Does contrast echocardiography with videodensitometric analysis detect altered left ventricular flow dynamics in patients with ventricular contractile abnormalities?
Does contrast echocardiography with videodensitometric analysis detect altered left ventricular flow dynamics in patients with ventricular contractile abnormalities?
Clearance of contrast from the mid-left ventricular cavity is prolonged in patients with left ventricular dysfunction, which correlates with ejection fraction and wall motion index.
No takes yet. Share an insight, caveat, or question.
Contrast videodensitometry may detect altered LV flow in contractile dysfunction; leaves open incremental prognostic value beyond EF.
Mizushige et al. (1993) studied this question.
