Twelve patients with dextro-transposition of the great vessels (age eight months to four years) were studied by echocardiography following Mustard's procedure. Nine of them had also been studied preoperatively. Postoperatively all patients demonstrated structural echoes in the atrial cavity behind the pulmonary root. In ten, the motion pattern generally resembled that of a stenotic atrioventric...

abstract accurate water measurement and delivery are basic issues in irrigation networks management and performance. in this regard, baffle modules have been considered as appropriate means for delivering almost constant discharge within a specific range of upstream water variation. the structure is meant for low discharge delivery and could be employed in farm irrigation. however, the design c...

Pulsed Doppler evaluation of pulmonary venous flow was performed in three groups of patients who had undergone either a Mustard or Senning procedure. Group I consisted of 43 patients in sinus rhythm who had undergone the Mustard procedure 9 months or more before the Doppler examination and 16 who were evaluated immediately after surgery. Group II consisted of 12 patients in sinus rhythm who had...

From May 1963 to July 1972, 123 patients ranging in age from 20 days to 15 years, with Dtransposition of the great arteries, underwent an intraatrial baffle operation using a pericardial baffle. They previously had had a total of 121 various palliative procedures. Twenty-six children (21%) died in the early postoperative period. The operative mortality was 13% in transposition of the great arte...

Natural convection heat transfer in a square enclosure with a horizontal baffle at the centerline of the left wall containing Al2O3-water in the presence of a magnetic field is investigated numerically. The top and bottom horizontal walls are adiabatic. The left wall and the baffle are maintained in constant temperature Th and the right wall is maintained in...

In this paper, the sloshing response of liquid in a two dimensional rigid rectangular tank with rigid baffles is investigated using boundary element technique. A baffle is a supplementary structural element which supplies a kind of passive control on the effects of ground shaking. The complicated liquid domain is divided into two simple sub-domains so that the liquid velocity potential in each ...

Recently, sulfate-reducing granular sludge has been developed for application in sulfate-laden water and wastewater treatment. However, little is known about biomass stratification and its effects on the bioprocesses inside the granular bioreactor. A comprehensive investigation followed by a verification trial was therefore conducted in the present work. The investigation focused on the perform...

We report the innovation of both a partly-covered and completely-covered, variable-diameter, balloon-expandable stent that was custom-designed by NuMed, Inc for percutaneous closure of a baffle leak after total caval pulmonary connection (TCPC). A 50-year-old patient, born with tricuspid atresia, who had undergone TCPC, developed severe persistent cyanosis due to a right-to-left shunt through a...

Results From August, 2010 to July, 2015, 45 children (median age 3.6 years, range 1.5 18.9 years) have undergone a Y-graft Fontan. In all 45 patients, echocardiography was unable to visualize the Y-arm connections to the branch PA’s. Thirty-nine patients underwent CMR a median of 9 days after Fontan (range 4-295 days), and 6 patients with pacemakers underwent CTA. Early in the experience, time ...

SUMMARY Eleven childrern with uncomplicated transposition of the great arteries repaired by the Mustard procedure were studied by atrial pacing, cardiac catheterization, and ciiieangiography. Nine had persistent postoperative ectopic cardiac rhythms. Atrial pacing in five suggested sinus node damage in four and A-V junctional conduction tissue damage in one. In seven children dye-dilution curve...
