[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.

The syndrome of congenital absence of the pulmonary valve: pathological, clinical and surgical considerations.

Four cases of congenital absence of the pulmonary valve are described. Three of them underwent successful operation. The fourth case, operated on in the first days of life, died because of severe respiratory distress. After examining the embryological aspects of this malformation, its treatment is discussed in relation to particular respiratory problems in infants and to the possibility of inserting prosthetic valves in children undergoing elective surgical treatment.

Congenital coronary artery fistula: report of five patients, diagnostic problems and principles of management.

The detection of a coronary artery fistula (CAF) is usually by chance and, because of the to-and-fro characters of the murmur, a misdiagnosis of a patent ductus arteriosus is frequently made. Correct diagnosis can only be reached after hemodynamic investigation completed by angiography. This lesion is often accompanied by few or no symptoms in infancy, but may become symptomatic with aging even if the shunt is small: complications such as endocarditis, rhythm disturbances, aneurysmatic dilation and rupture have been reported. Five cases of CAF have been studied in our institution: 3 of them have been operated upon in extracorporeal circulation with good results. Principles of management are controversial: many authors advocate delay of treatment until symptoms appear: in our opinion, based on the natural history of the disease and on our experience, closure of the fistula in pediatric age, even in asymptomatic patients, is the treatment of choice.
