Background  To examine two different operation timing for treating patients with a total anomalous pulmonary venous connection (TAPVC) who need emergency surgery and to summarize the effects of the two operation strategies.    Methods  A retrospective review of 54 patients with TAPVC who underwent operations within 72 h of presentation between December 2010 and July 2019 at a single institution was conducted. All patients exhibited respiratory or hemodynamic instability that required mechanical ventilation and inotropic support. Forty-four patients received emergency operations between 24 to 72 h due to stabilization of the patient’s condition. Stable hemodynamics were achieved, and a stable internal milieu was maintained before the operation. These patients comprised the Stable group (SG). Rather than being subjected to efforts to obtain stable hemodynamics and maintain a stable internal milieu, ten patients received emergency operations immediately within 24 h of diagnosis or an emergency operation is performed immediately due to uncorrectable acidosis or progressive cardiovascular collapse. These patients comprised the Unstable group (UG). The hospital course, operative data, and outpatient records were reviewed.    Results  In SG group, there were 23 exhibited the supracardiac type, 15 exhibited the cardiac type, 4 exhibited the cardiac type, and 2 exhibited the mixed cardiac type,3 patients were premature, the rest was term infant, PDA was the most common comorbidities (28 patients), the next is severe tricuspid valve regurgitation (21 patients). In UG group, there were 3 exhibited the supracardiac type, 4 exhibited the cardiac type, 3 exhibited the cardiac type, and no patient exhibited the mixed cardiac type, only 1 patient was premature, the rest were term infant. PDA (6 patients) and severe tricuspid valve regurgitation (5 patients) were the top two comorbidities. The median weight, median age at surgery, mean cardiopulmonary bypass (CPB) duration and mean aortic cross-clamp (ACC) duration were not significantly different between the two groups. The median postoperation durations of ventilator support were 8.1 ± 4.6 (2–13) days in the SG group and 4.9 ± 2.1 (2–18) days in the UG group, resulting in a significant difference ( p  = 0.008), the Post-op days in ICU and Days of hospitalization were 8.64 ± 4.04 days and 19.9 ± 4.27 days in the SG group and 5.6 ± 2.01 days and 14.7 ± 1.75 days in the UG group ( P  = 0.026 and 0.002). There were 12 hospital mortalities (27.3%) in the SG group and 2 hospital mortalities (20%) in the UG group, resulting in no significant difference in mortality ( p  = 0.636). Postoperative complications, such as low cardiac output and arrhythmia, were not significantly different between the two groups. The survival rates in the UG and SG groups at 5 years were 87.5 and 89.9%, respectively. There was no difference in survival between the two groups at the latest follow-up (SG group 89.9% versus UG group 87.5%,  p  = 0.8115).    Conclusion  An emergency operation should be performed immediately without any delay, it can reduce duration of mechanical ventilation and Days of hospitalization without reducing mortality.
