[Isolated straddling tricuspid valve. Presentation of 2 cases operated on successfully].
During the period May 1977-September 1983 in the Department of Cardiac Surgery of Massa Hospital two patients with isolated straddling tricuspid valve were studied with cardiac catheterization and selective angiocardiography and subsequently underwent surgical correction. The first patient, a 38-month-old white boy presented with "complete straddling" according to Bharati and Lev classification; the second, a 39-month-old white boy presented with "peripheral straddling". In both cases at surgery the ventricular septal defect was closed with a Teflon patch, sparing the chordae tendinae and the "straddling" papillary muscle. Both patients survived operation. The first one developed a complete atrioventricular (A-V) block with a ventricular rate which never was below 80 beats/min, during the 30 days of in-hospital observation. No permanent pacemaker was therefore inserted. The follow-up controls (39 and 79 months respectively) shows both patients to be hemodynamically and functionally well.
