 | | Real time echocardiography may be a promising technique in the study of this patients. | | | The marked right ventricular hypertrophy is due to the fact that it should support systemic pressures. | | | Albert procedure (Mayo Clinic 1969) is probably the best way to approach patients with associated VSD and hypoplastic pulmonary artery, using an aortic homograft to create an external liaison between the right ventricle and distal pulmonary artery. |

| | Differences between the right and left ventricle: |
| | The technique has been used to examine the performance of the right ventricle during separation from cardiopulmonary bypass and has been found to be of some use. | | | However, the accuracy of the technique is still in question and it remains to be seen whether right ventricular ejection fraction measurement offers patients any clear benefit or whether it is still a technique in search of a role. | | | The introduction of rapid response time thermistors into clinical practice allowed for the development of thermal dilution techniques which permitted the estimation of right ventricular end-diastolic volume, end-systolic volume and ejection fraction. |

| | Most likely, the central valve connects the right atrium and the left ventricle (as in our patient) or the left atrium and the right ventricle, depending on the position of the inlet septum. | | | Atrioventricular endocardial cushions may fuse at the left side of the inlet septum (as in our patient), at the right side (not yet described in the literature), or not at all (as in atrioventricular canal defects). | | | The valves described as double-orifice mitral valves in the medical literature are the 2 left-sided atrioventricular valves, which have the same basic anatomical structure. |

| | Ventricle and a half |
| | The systemic ventricle is vented with a cannula placed in the right superior pulmonary vein. | | | The ventricle-and-a-half repair can be considered the last stage of the functional single ventricle pathway, in that the systemic and pulmonary circulations are entirely separated, and there is no compelling reason to perform a more traditional Fontan operation. | | | This is because the patient would be considered to be almost entirely dependent on the shunt for pulmonary blood flow, and no significant forward flow is likely to be found via the right ventricle. |
