[Prognostic study of single ventricle with respect of anatomical and clinical data].

The authors analysed the anatomical and clinical prognostic factors of single or common ventricle. This retrospective study was based on a series of 185 patients hospitalised between 1/2/70 and 31/12/91 in the paediatric cardiological unit of the Cardiological Hospital of Lyon with this condition. A number of anatomical and clinical parameters were identified in this population. For each parameter, a given patient could only relate to single modality and a survival graph determined by Kaplan-Meier analysis was established for each modality. For each variable, the survival curve of the most frequently encountered modality served as a reference and the other modalities were compared with it using a logrank test. The different modalities potentially related to patient survival were then entered into a multivariable model using logistic regression. The results of this study of multivariable analysis using the Odds-Ratio (OR) independently suggest that four variables may influence negatively survival of patients with a single ventricle: pH < or = 7.3 on admission (OR = 3.55), a non-left ventricular morphology of the main ventricular chamber (OR = 3.11), the presence of an obstacle on the aortic outflow (OR = 5.58) and a total anomalous pulmonary venous drainage (OR = 26.88).
