Chronic and adjustable pulmonary artery banding

Abstract

This device allows adjustment of the pulmonary artery cuff in a precise manner over a prolonged period of time without surgical reintervention. Potentially, the device might have applications for clinical use in children with congenital heart disease.

Modification of Trusler's Formula for the Pulmonary Artery Banding

“…This has led to the development of several adjustable PAB devices [6][7][8]. However, none of these devices have gained widespread clinical use since they are expensive special equipment, unreliable and lacking reproducibility of adjustments.…”

Evaluation of a Percutaneously Controlled Hydraulic Occluder in a Rat Model of Gradual Venous Occlusion

“…Various fluids have been used to fill HOs during acute and chronic studies, including normal saline, 29 hypertonic saline, 30 water, 31 radiographic contrast solutions, 32 indocyanine green dye, 33 and dextrose solution 34 . Manufacturer recommendations at the time of this study indicated that high molecular weight substances would be preferred for maintenance of chronic inflation so that there would be minimal diffusion from the silicone HO.…”

Novel pulmonary artery banding followed by transcatheter balloon dilatation in treatment of complex congenital heart defects

“…Histologické změny při použití goretexových proužků k BP navíc neukázaly destrukci elastických membrán, nekrózu medie, nápadnou zánětlivou infi ltraci nebo snížení četnosti vasa vasorum. Tyto nálezy jsou lepší než při použití jiných materiálů v dříve publikovaných studiích [7,8]. Postupné snížení tlakového gradientu na kmeni plicnice v oblasti bandáže po balonkové angioplastice (ze 42 mm Hg a 60 mm Hg na 30 mm Hg a 25 mm Hg) pozorované u našich pacientů může být spojeno s postupným snížením levopravého zkratu reziduálními komorovými defekty.…”
