Sutureless Technique and Conventional Repairs for Total Anomalous Pulmonary Venous Connection: an Observational Study by Chinese Heart Centers

An observational, non-randomized multi-center study is proposed to compare the efficacy between conventional repair and sutureless technique for total anomalous pulmonary venous connection. Subjects will be enrolled at Guangdong Provincial People's Hospital (GPPH) and three to five participating hospitals. All clinical interventions will follow the participating hospital's standard of care. Informed consent will be obtained from all study participants before study enrollment. After undergoing their surgical repairs, study participants will be followed up at 1, 3, 6 and 12 months after initial surgery and annually thereafter. All preoperative and postoperative medical records data will be submitted to a centralized database at GPPH through a secure online research platform.

Baseline and post-operative (6 months) assessments will include a history and physical examination, a quality of life survey, physical examinations, liver and kidney function assessments, serum brain natriuretic peptide (BNP), echocardiography and electrocardiography. Besides, a small amount of common pulmonary vein tissue may be required for hematein and eosin staining.
