1. Echocardiography is diagnostic for univentricular hearts with two AV-valves. 2. Echocardiography does not substitute catheterization and angiocardiography, it is, however, apt to optimize and to supplement invasive procedures. 3. The number, the relative size, and the function of the AV-valves can be ascertained by echocardiography. 4. The relation of the great arteries may be suggested by transducer direction and position. 5. Echocardiographic measurements are indicative of relative pulmonic flow: Therefore echocardiography should be helpful in follow up studies. 6. Valvar and valvar-subvalvar pulmonic outflow obstructions may be suggested by echocardiography. 7. Septal remnants may be recognized by echocardiography. How significant their demonstration is to outlet chamber definition has still to be clarified. |
