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...

Flow in a circular pipe fitted with segmental baffles may be treated as a shellwithout-tube system. Its pressure drop has been calculated by adapting the Kern correlation [1] for pressure drop in the shell side of shell-and-tube heat exchangers. The Kern correlation is essentially based on the Hagen – Poiseuille equation for laminar flow, but flow visualization results presented here show that ...

We have recently used the Amplatzer septal occluder to close Fontan fenestrations. Between June 1998 and December 1999, 13 patients underwent transcatheter occlusion of their Fontan fenestrations. Systemic blood flow decreased significantly without a concomitant decrease in pulmonary blood flow. All residual shunts detectable by oximetry were at sites separate from those into which occlusion de...

A 34-year-old man with complete transposition of the great arteries (D-TGA) presented for the first time to our clinic. He previously underwent balloon atrial septostomy (Rashkind procedure) early after birth followed by a Senning procedure at the age of 2 months together with ligation of a patent ductus arteriosus. He has been asymptomatic since his surgery. Transthoracic echocardiogram was te...

Coronary artery embolism is an uncommon cause of acute myocardial infarction (MI). We present a patient with pulmonary atresia and severe right heart hypoplasia who underwent a lateral tunnel Fontan procedure in childhood and presented with an acute ST-segment elevation MI at 19 years of age. In addition to the known risk of thrombotic complications associated with a Fontan circulation, potenti...

sloshing is a well-known phenomenon in liquid storage tanks subjected to base or body motions. in recent years the use of multiple vertical baffles for reducing the sloshing effects in tanks subjected to earthquake has not been taken into consideration so much. on the other hand, although some of the existing computer programs are capable to model sloshing phenomenon with acceptable accuracy, t...
