BACKGROUND The "fenestrated Fontan" (surgical baffle fenestration followed by transcatheter test occlusion and permanent closure after postoperative recovery) was adopted in an effort to reduce perioperative mortality and morbidity. This study assesses the effect of baffle fenestration on outcome. METHODS AND RESULTS Patients having a modified Fontan operation with a cavocaval baffle and cavo...

Thirty children aged from 7 weeks to 14 years were examined by echocardiography after Mustard's operation for transposition of the great arteries. Discrete and persitent echoes were noted within the original left atrial cavity and contrast echocardiography was used to establish that these originated from the interatrial baffle. In the presence of caval channel obstruction, caused by malposition...

A baffle puncture is a challenging procedure but can be safely done using direct visualization of the region of interest. To our knowledge, however, it has never been performed in a patient with dextrocardia. We present a 62-year-old male with dextrocardia, right isomerism, congenitally corrected transposition of the great arteries, persistent left-sided superior and inferior caval veins, atria...

Convective heat transfer and entropy generation in a 3D closed cavity, equipped with adiabatic-driven baffle and filled with CNT (carbon nanotube)-water nanofluid, are numerically investigated for a range of Rayleigh numbers from 103 to 105. This research is conducted for three configurations; fixed baffle (V = 0), rotating baffle clockwise (V+) and rotating baffle counterclockwise (V−) and a r...

Sloshing refers to a certain kind of fluid movement that changes as it progresses. It possesses properties are both nonlinear and exceedingly unpredictable, these affect the tank wall. This effect may lead structural wear, which in turn can cause fail. Benzene gasoil liquids used test sloshing liquid accompanying pressure on wall caused by baffles partially full tanks. To attain this, modeling ...

Clinicians have a difficult choice between the arterial switch (Jatene et al.) and the atrial baffle operation (Mustard or Senning) for transposition of the great arteries. The surgical decision is essentially a determination of whether the long-term course after the arterial switch procedure (thought to be more favorable than after the atrial baffle procedure) plus elimination of presurgical a...

To the Editor Mustard operation, a surgical treatment for transposition of great arteries, can be complicated by postprocedural atrial or caval baffle leaks, which lead to about 60% of late reoperations. Transcatheter procedures for baffle leakage closure have been anecdotally reported and shown to be both well tolerated and effective; however, no data have been reported to date about the short...
