Comparative Study Clinical TrialTransesophageal echocardiographic evaluation of native aortic valve area: utility of the double-envelope technique.
To assess the accuracy of aortic valve area (AVA) calculations using the continuity equation with data obtained from the double envelope (DE) (simultaneously obtained left ventricular outflow tract [V1]) and aortic valve [V2] velocities) during intraoperative transesophageal echocardiography (TEE). ⋯ TEE evaluation of native AVA using the DE technique is feasible and in good agreement with that obtained by C/TTE and G/CATH. Compared with DE/TEE, PL/TEE did not agree as well. Use of DE/TEE should simplify the continuity equation and may minimize errors resulting from beat-to-beat variability in stroke volume.

Clinical TrialTechniques and complications of one-lung ventilation in children with suppurative lung disease: experience in 15 cases.
To evaluate lung isolation with Fogarty catheters and to analyze respiratory consequences of one-lung ventilation (OLV) in children with suppurative lung disease. ⋯ The use of Fogarty embolectomy catheters for lung isolation in children undergoing thoracotomy is recommended. Respiratory problems are not rare during OLV in children with suppurative lung disease and require immediate management.
