Total anomalous pulmonary veins connection: the perioperative risk factors

ABSTRACT

Operative reconstruction of total anomalous pulmonary veins connection [TAPVC] in the literature has high morbidity and mortality. The aim of the study was to investigate the perioperative risk factors to lower the mortality rate. We retrospectively studied the cases of 42 infants operated for Total Anomalous Pulmonary Veins Connection between August 2002 to August 2007 at Damascus University Cardiovascular Surgical Center. We evaluate the role of right ventricle pressure, Left Ventricle End Diastolic Volume [LVEDN], the anatomical type of anomalous, age and weight of patients, pulmonry infections and delay in doing surgery as perioperative risk factors. Our study demonstrates that neither Left Ventricle End Diastolic Volume nor RV pressure were risk factors. Pulmonary infections secondary to long-standing pulmonary congestion was the only important risk factor. It is highly recommended to operate in the first months of life before the occurring of any pulmonary infection
