Heterotopic liver transplantation: Temporary solution, permanent problem?

Heterotopic Auxiliary Liver Transplantation With Portal Flow

One of the causes of auxiliary liver transplantation failure is the inter-liver competition between the host liver and the graft for the hepatotrophic factors of the portal blood. We have developed an experimental model of heterotopic partial (30%) liver isotransplant using Wistar rats so as to study this competition. Splenoportography and dissection demonstrate the existence of collateral circ...

Permanent and temporary pacemaker implantation after orthotopic heart transplantation.

PURPOSE:To determine the indication for and incidence and evolution of temporary and permanent pacemaker implantation in cardiac transplant recipients. METHODS: A retrospective review of 114 patients who underwent orthotopic heart transplantation InCor (Heart Institute USP BR) between March 1985 and May 1993. We studied the incidence of and indication for temporary pacing, the relationship betw...

A permanent solution for a temporary problem: transcatheter valve-in-valve implantation for failed transcatheter aortic valve replacement.

Over the past decade, transcatheter aortic valve replacement (TAVR) matured from an adventitious endeavor in the early years to an established and paradigm-changing treatment option for many patients with severe aortic valve stenosis. However, lack of long-term data on device performance as well as the obvious presence of procedure-specific complications currently limit the expansion of this te...

Bradyarrhythmias, temporary and permanent pacing.

Bradycardia is common in critical care units. It may be transient, asymptomatic and of little consequence, or life-threatening. Bradycardia may result from abnormalities of the sinus node, atrioventricular node, or the His-Purkinje system. It may also be precipitated by drug effects or enhanced vagal tone. Proper diagnosis is pivotal to determining prognosis and management. Temporary and perman...
