Background: The Ross procedure has been known as a good method for aortic valve replacement. Pulmonary allograft postoperative stenosis subsequent to the Ross procedure has been noted as an important disadvantage of this technique, although risk factors related to this complication are not clearly recognized. In this study we evaluate the risk factors of pulmonary allograft stenosis after Ross ...
OBJECTIVE To compare the frequency of valvar and supravalvar aortic stenosis in homozygous and heterozygous familial hypercholesterolaemia (FH). DESIGN Analysis of life time cholesterol exposure and prevalence of aortic atherosclerosis in 84 consecutive cases attending a lipid clinic. SETTING A tertiary referral centre in London. PATIENTS Outpatients with FH (six homozygous, 78 heterozygo...
Balloon dilatation valvuloplasty was performed in 16 patients with pulmonary valve stenosis aged 10 days to 17 years. Gradients were reduced in all but two patients and were less than or equal to 20 mm Hg after the procedure in all but these two and one other. Unsatisfactory initial results in these three patients were attributed to the use of too small a balloon in one patient (gradient subseq...
critical pulmonary valve stenosis (cpvs) and atrial septal defect (asd) is an uncommon form of congenital heart disease. concurrent transcatheter pulmonary valvuplasty and closure of secundum atrial septal defect appears to be an interesting alternative to surgical correction. we present the simultaneous balloon valvuloplasty of critical pulmonary stenosis (ps) with supra systemic right ventric...
