BACKGROUND AND OBJECTIVES We investigated the effectiveness of balloon dilatation of homograft conduits in the pulmonary position in delaying surgical replacement. SUBJECTS AND METHODS We reviewed the medical records of patients who underwent balloon dilatation of their homograft in the pulmonary position from 2001 to 2015. The pressure gradient and ratio of right ventricular pressure were me...
called homografts. In the literature confusion exists with the use of terms: homografts, autografts, xenografts and allografts in cardiac surgery. Specifically, with the terms homograft and/or autograft many surgeons referred to the grafts coming from the patient himself (eg the transposition of the pulmonary valve to the aortic position – Ross procedure), while allograft was called the graft d...
We describe a repeat aortic root replacement using a cryopreserved aortic homograft in a patient with active composite valve-graft endocarditis and an aortic root abscess. At the second surgery, infected prosthetic material was removed and surrounding tissue was radically debrided. The cryopreserved aortic homograft was positioned using the full root technique with a concomitant coronary bypass...
OBJECTIVE To assess autograft, homograft and ventricular function, as well as exercise capacity, in adult patients who have undergone the Ross procedure. SETTING Single centre paediatric and adult congenital heart disease unit. Patients 45 subjects (24.6 years, range 16.9-52.2 years) who underwent the Ross procedure between 1994 and 2006 (8.1 years after the Ross operation, range 2.0-14.0 yea...
Endocarditis was encountered on an aortic homograft valve in 14 of 539 patients, giving a total incidence of 2.6%. It was an early postoperative complication in five patients (0.9%), and only one of these survived. Four hundred and six hospital survivors were followed for periods up to 76 mo. Nine of these patients (2.2%) developed infection of the homograft valve 11 to 66 mo postoperatively an...
The genotype of homograft kidneys plays the primary role in determining chronic blood pressure levels in two strains of rats with opposite genetically controlled propensities for hyptertension. In hypertensive rats from the hypertension-prone (S) strain, a renal homograft from the same strain resulted in a slight rise in blood pressure to a level that was equivalent to that in appropriate unine...
The purpose of this case is to describe the complex perioperative management of a 30-year-old woman with congenital heart disease and multiple resternotomies presenting with pulmonary homograft dysfunction and evaluation for percutaneous pulmonary valve replacement. Transvenous, transcatheter Melody valve placement caused left main coronary artery occlusion and cardiogenic shock. An Impella ven...
