Looking Inside the Third Generation Left Ventricular Assist Device Using Color Doppler Transesophageal Echocardiography
HeartWare is a third-generation continuous flow left ventricular assist device (LVAD) and generates centrifugal pattern of blood flow. In the perioperative setting, interrogating the HeartWare devices is very difficult due to the interference of the Doppler by the impeller frequency and generation of the waterfall artifact. We present a case where using color Doppler a view "inside" the impelle...
متن کاملApplication of centrifugal pump in right ventricular failure due to pulmonary artery hypertension. (A case report)
Background: It has not been yet developed a ost suitable method to treat right ventricular failure due to pulmonar artery hypertention resulted from ventricular arrhythia. Though some case reports about patients ready to heart transplant using left assist device or biventral assist device as bridge have been published in Journals, but nocase concerning application of centrifugal pump for treatm...
متن کاملDesign an Equivalent Left Ventricular Assist Device for Medical Equipment Labs
LVAD is a mechanical pump supporting a weak heart function and blood flow. Sometimes, the heart may not recover fast enough to take over the pumping action immediately after surgery, in such patients a temporary support device has been employed to maintain the pumping action until the patient’s own heart recovers. This device can be considered as a temporary alternative before the process of ar...
متن کاملA case of coronary cameral fistula.
An 85-year-old woman underwent transthoracic echocardiography for the investigation of breathlessness and atypical chest discomfort. Clinical examination was unremarkable. A standard 12 lead ECG demonstrated anterior T wave inversion, but was otherwise normal. Transthoracic echocardiography demonstrated a normally functioning left ventricle with hypertrophy and trabeculation of the apical and l...
متن کاملDoppler left ventricular flow pattern versus conventional predictors of left ventricular thrombus after acute myocardial infarction.
OBJECTIVES The value of Doppler-derived left ventricular spatial flow patterns in predicting left ventricular thrombus formation after myocardial infarction was compared with that of conventional clinical and echocardiographic variables. BACKGROUND Assessment of left ventricular thrombosis risk after myocardial infarction is important because of potential embolic sequelae that are reduced by ...
