Ross procedure in children

Abstract

Institute of Cardiovascular Diseases, ChennaiBackground: Right ventricle to pulmonar T arter T conduits are a necessar T part of the pediatric cardiac surgical armanmntariunL While homografls have been the main stay of such situations the search for other conduits continues. Commercially available bovine jugular vein preparations like Contegra | are vet T expensive in the Indian scenario.Methods: We have used bovine jugular veins, procured and prepared by us locally in 15 patients undergoing a range of pediatric cardiac surgical procedmes including truncus arteriosus repair, tetralogy correction and Rastelli procedmes. The mean age of these patients was 1.6 years. Bovine jugular vein conduits in the size ranges of 12 16 mm were used in these patients.Results: The mortality in this group was 2. Postoperative RV to PA gradients in these patients have been recorded below a mean pressure of 10ram Hg. Postoperative echocardiography assessment revealed well functioning conduits with good valve competency. Follow up period ranges from 3 months to 1 year and no patient has required reintervention or conduit change.Conclusions: The ready availability of bovine jugular vein off the shelf as it were, the smaller sizes, cheaper preparation method and good surgical handling characteristics makes it an attractive option for RVOT conduits.

Practical Synthesis of Aromatic Dithiocarbamates

“…[6,14,15] However, this is not the case for diaryl DTCs; at present only a few syntheses have been reported, mostly for simple N,N -diphenyl DTCs. [16,17,18] Diaryl DTCs, particularly those with electron-donating substituents, are of strong interest for studies in molecular electronics, but to our knowledge a general synthetic procedure is lacking. This may be due partly to the oxidative sensitivity of electron-rich diarylamines, which are challenging to isolate in neutral form.…”
