The conduction system in truncus arteriosus and its surgical significance

Truncus arteriosus

Truncus Arteriosus

We have encountered difficulty in recognizing and identifying clinically true truncus arteriosus with pulmonary arteries (type 1) because of its resemblance to correctable cardiac defects such as patent ductus arteriosus, aortic-pulmonic defect, and ventricular septal defect. In the present report we are presenting clinical information on 14 patients with this anomaly, both to supplement the sc...

Early and late results of surgical repair of truncus arteriosus.

Ninety-two patients had corrective operation for truncus arteriosus between 1967 and 1975. During the first 30 days after surgery, 23 patients died. No significant differences appear between early mortality and sex, type of truncus, variations in pulmonary arterial anatomy, truncal valve regurgitation, associated anomalies, previous operation, or duration of extracorporeal circulation. Greater ...

Selection of Patients with Truncus Arteriosus for Surgical Correction

Six years have passed since the first successful surgical correction of truncus arteriosus. A review of our experience enables some conclusions regarding the operation. Patients with mild or moderate truncal valve incompetence do not need truncal valve replacement. Patients with severe truncal valve incompetence require valve replacement, which is associated with a significantly increased surgi...

Persistent Truncus Arteriosus

PERSISTENT truncus arteriosus is one of the rarer congenital cardiac anomalies. Keith et al.1 cite the incidence to be less than 1 per cent of their congenital cardiac patients Abbott2 found 21 in her autopsy series of 1,000 cases and Wood3 had one in his clinical series of 900. Collett and Edwards4 reviewed, in an excellent study of 80 autopsied cases, the pathology of truncus arteriosus. The ...
