BACKGROUND The distal splenorenal shunt (DSRS) is designed to maintain hepatopetal portal vein flow while decompressing gastroesophageal varices. However, over time, as the underlying liver disease progresses, the DSRS loses its selectivity. The most common method of addressing this issue during orthotopic liver transplantation is shunt ligation with or without splenectomy. Dismantling the shun...

transannular patch was placed and stent flow was interrupted with a clip. A 1500-g neonate diagnosed with pulmonary atresia with ventricular septal defect, right aortic arch, ductus left and left superior vena cava, was administered prostaglandin to 2 months and underwent a right MBT shunt. Prostaglandin perfusion was restarted at 24 h as saturation was <65%. Echocardiography detected no flow i...

Abstract All amniotes except birds and mammals have the ability to shunt blood past the lungs, but the physiological function of this ability is poorly understood. We studied the role of the shunt in digestion in juvenile American alligators in the following ways. First, we characterized the shunt in fasting and postprandial animals and found that blood was shunted past the lungs during digesti...

Gerbode defect is a rare type of left ventricle to right atrium shunt. It is usually congenital in origin, but acquired cases are also described, mainly following infective endocarditis, valve replacement, trauma or acute myocardial infarction. We report a case of a 50-year-old man who suffered an extensive and complex infective endocarditis involving a bicuspid aortic valve, the mitral-aortic ...

Twenty nine patients with isolated perimembranous ventricular septal defects were investigated by M mode, cross sectional, and pulsed Doppler echocardiography. Tricuspid valve anomalies were present in all six patients with a left ventricular-right atrial shunt but in only six (26%) of 23 patients who had interventricular shunts only. Systolic flutter of the tricuspid valve was shown in five (8...

Partial muscular inter-ventricular septal defect (VSD) or Pacman heart is a rare congenital or occasionally acquired anomaly. Concurrent Pacman heart and Shone's complex are extremely rare and have never been reported until now. We described a 37-year-old male patient with congenital Pacman heart, flail mitral valve (FMV), and a history of multiple congenital anomalies, including subvalvular ao...

BackgroundThe purpose of this study was to quantitate the degree of left-to-right shunt in patients with secundum atrial septal defect (2o ASD) with the PISA method and compare the results with the usual continuity equation. Although the PISA method has been used extensively for the quantitative measurement of regurgitant severity and valve area in patients with valvular regurgitation and steno...

A PediaSat™ oximetry catheter (PediaSat: Edwards Lifesciences Co., Ltd., Irvine, CA, U. S. A.), which facilitates continuous measurement of central venous oxygen saturation (ScvO2), may be useful for surgery for pediatric congenital heart disease. We used PediaSat during a bidirectional Glenn shunt. The patient was a 13-month-old boy. Under a diagnosis of left single ventricle (pulmonary atresi...

A 75-yr-old female presented with platypnoea and orthodeoxia, shortly after laying down an old and pinching corset. The injection of activated Haemaccel in the right cubital vene during transoesophageal echocardiography, in the upright position, revealed a direct blood flow from the superior caval vein at a patent foremen ovale, consequently opening it and causing a large right-to-left shunt wh...

Dye dilution and cardiac catheterization technics were used to study 36 patients with a central left-to-right shunt due to patent ductus arteriosus, atrial septal defect or ventricular septal defect. The configuration of dilution curves following injection of dye into an antecubital vein was similar in all instances. Principal abnormalities of the curve were a prolongation of its disappearance ...
