摘要
Background Thoracoscopic minimally invasive pectus excavatum repair （Nuss operation） features its little trauma, simple, short operation time, and good outcome compared with traditional treatment of pectus excavatum surgery-sternal elevation （Ravitch operation） and sternal turnover. The effect of the operation on patients＇ heart and heart function remains unclear. This study aimed to understand the changes of electrocardiogram and cardiac function after Nuss procedure. Methods From 2008 January to 2013 July, thoracoscopic Nuss operation was performed in 217 patients with pectus excavatum. All the patients underwent the preoperative, postoperative detection of ECG and cardiac function in 3 months to 1 year after operation. Results After 3 months to 1 year follow-up, arrhythmias persisted in 46 out of 135 patients with preoperative symptoms （P 〈 0.05）; Stroke volume and cardiac output significantly increased （P 〈 0.05）; And cardiac parameters greatly improved （P 〈 0.05）. Conclusions Minimally invasive repair of pectus excavatum deformity can correct the chest malformation, alleviate arrhythmia, and improve cardiac function.
