Case ReportsStent implantation for post-Mustard systemic venous obstruction.
In this paper, we report on the use of stents in the treatment of late-onset post-Mustard systemic venous obstruction in three patients with clinical signs of obstructive caval syndrome. After unsuccessful balloon dilation, Palmaz-Schatz stents were implanted at the veno-atrial junction. ⋯ After 26+/-4 months of non-invasive follow-up, no signs of recurrent stenosis were observed. Stent implantation is effective in the treatment of systemic venous obstruction after Mustard operation.

Comparative StudyPreconditioning of the latissimus dorsi muscle in cardiomyoplasty: vascular delay or chronic electrical stimulation.
In standard single stage cardiomyoplasty (CMP), the latissimus dorsi muscle (LDM) is not preconditioned prior to surgery. We hypothesized that latissimus dorsi preconditioning by vascular delay or by chronic electrical stimulation would result in an improved LV hemodynamic function early (14 days) after CMP. ⋯ Preconditioning the LDM may play an important role in providing early cardiac assistance in CMP. Preconditioning the LDM with vascular delay resulted in improving performance of the LDM with consistent increases in LV hemodynamics. This was not observed after preconditioning with chronic electrical stimulation. Vascular delay of the latissimus dorsi can significantly improve muscle performance in CMP and could provide hemodynamic assistance early after surgery.
