PDA by Doppler echo.

Assessing prosthetic mitral valve regurgitation by transoesophageal echo/Doppler.

Transoesophageal echocardiography has greatly improved our ability to detect structural and regurgitant abnormalities associated with prosthetic mitral valves.

ROLE OF ECHO-DOPPLER In HEART FAILURE

The impact of heart failure (HF) on the global health care community is well recognized. Moreover the incidence and prevalence of HF is increasing, both in developed and developing countries. In the US alone, HF accounts for approximately 727,000 emergency department visits, 1 million hospital admissions with an estimated overall annual cost of about $ 29 billion way back in 2006 . However its ...

Dolichocarotids: echo-color Doppler evaluation and clinical role.

AIMS Dolichocarotids(DCs) represent a rare(2-6%) carotid imaging finding in the general population that may be free of clinical significance or be associated with cerebrovascular events. Their detection is traditionally assigned to carotid echo-color Doppler(ECD) and selective angiography(the standard method). The primary aim of this study was to estimate the sensitivity, specificity and accura...

Reconstruction of 3D Flow from Multiple Echo Doppler Views

We present a new method for reconstructing a 3D vector field from multiple 3D Pulsed Wave Doppler echo images. A weakness of Doppler imaging is that only a 1D projection of the true 3D velocity (the component of the velocity parallel to the echo beam direction) is measured. We propose a method to use registered multiple Doppler views to calculate 3D flow vectors using a Least Mean Squares (LMS)...
