Congenital Cardiac Defect

Brief summary

This study evaluates the association between perioperative echocardiographic Doppler findings and clinical outcomes in pediatric patients undergoing cardiac surgery. In our center, anesthesiologists perform transthoracic or transesophageal echocardiography during perioperative period routinely in children undergoing surgery for congenital cardiac disease. Echocardiographic findings include the doppler patterns of hepatic vein, portal vein, renal artery, renal vein and splenic vein before and after cardiopulmonary bypass. Portal pulsatility index, renal resistive index, and respiratory variations in peak aortic blood flow velocity and diameter of inferior vena cava are measured.

Design outcomes

Primary

Measure	Time frame	Description
Characteristics of Doppler values and its derived parameters of portal vein, hepatic vein, renal artery and vein, and splenic vein measured using echocardiography in children with congenital cardiac disease	after anesthetic induction until the end of surgery	To find the characteristics and standard values of Doppler findings measured by echocardiography before and after congenital cardiac surgery
Association between Doppler values measured by echocardiography and clinical outcomes after pediatric cardiac surgery	through study completion, an average 1-2 years	To evaluate whether Doppler values of portal vein, hepatic vein, renal artery and vein, and splenic vein measured using echocardiography can predict major adverse outcomes after pediatric cardiac surgery

Secondary

Measure	Time frame
Number of patients with major adverse outcomes after pediatric cardiac surgery	through study completion, an average 1-2 years
