Aortoventriculoplasty is a new method of treatment for left ventricular outflow tract obstructions. The concept is based on creating a surgical defect which is patched in such a way as to provide the largest possible outflow to the left ventricle. The incision of the aorta continues down as far as necessary, with the right ventricular wall, the aortic ring,(More)
Nineteen patients with tricuspid atresia and reduced lung perfusion (valvular-and/or subvalvular pulmonary stenosis, transposition of the great arteries and/or single atrium) were operated in the period 1975--1979. The surgical procedures employed varied according to the additional cardiac defects. The age of the patients was between 2 and 18 years. Eleven(More)
Results of aortoventriculoplasty (AVP) are reported in 21 patients with various types of left ventricular outflow tract obstruction (LVOTO). The concept of AVP is based on creating a surgical aortoseptal defect which is patched to provide the largest possible outflow tract to the left ventricle. Lesions consisted of isolated diffuse fibromuscular subaortic(More)
A new operative technic for widening the stenotic left ventricular outflow ("left ventricular tunnel") is described and a clinical case is reported. A vertical incision along the anterior aspect of the aorta descends with a slight angle across the outflow tract of the right ventricle. After aortic valvectomy the ventricular septum is cut between the left(More)
Aortoventriculoplasty (AVP) is an established operative procedure for the enlargement of different types of severe left ventricular outflow tract obstruction. Between 1974 and 1985 75 aortoventriculoplasties were carried out in 72 patients ranging from 5 to 34 years of age. Three patients had to be reoperated upon due to significant right ventricular(More)
