Abstract:
Objective To investigate the indications and clinical effects of tricuspid cone reconstruction and tricuspid valve replacement in the treatment of downward displacement of tricuspid valve (Ebstein anomaly). Methods The clinical data of 22 patients with Ebstein anomaly who underwent surgical treatment in our hospital from January 2013 to March 2020 were collected. There were 7 males and 15 females, aged 4-56 (33.68±17.78) years. The patients were divided into two groups according to different surgical methods: a tricuspid cone reconstruction group (tricuspid valvuloplasty group, n=12) and a tricuspid valve replacement group (n=10). The curative effect of the two operative methods were compared. Results Twenty-two patients underwent surgical treatment under general anesthesia and cardiopulmonary bypass. One patient died of severe low cardiac output syndrome during operation. Downward displacement of tricuspid septum was found in 22 patients, and downward displacement of tricuspid septum and posterior septum in 21 patients, downward displacement of tricuspid in 8 patients. Twelve patients were treated with tricuspid valvuloplasty, 10 patients with tricuspid valve replacement, and patients with other intracardiac structural malformations were treated at the same time. Postoperative cardiac doppler ultrasound indicated no tricuspid regurgitation in 9 patients, mild regurgitation in 8 patients, and moderate regurgitation in 4 patients. No perivalvular leakage occurred in all patients undergoing valve replacement. Four patients developed degree Ⅲ atrioventricular block after operation, among whom 3 patients recovered to sinus rhythm and 1 patient implanted the permanent pacemaker. Twenty-one patients were cured and discharged after successful operation, and were followed up for 3 to 78 months, with a follow-up rate of 100.0%. During the follow-up period, there was no severe tricuspid regurgitation in tricuspid valvuloplasty group, but mild or moderate regurgitation was found. After tricuspid valve replacement, only 1 patient had mild regurgitation, and the rest patients had no valve regurgitation. Conclusion Tricuspid valvuloplasty and tricuspid valve replacement are effective in the treatment of Ebstein anomaly, and the tricuspid regurgitation is less severe after tricuspid valve replacement operation. The operation method should be selected according to the different anatomical characteristics and condition of tricuspid valve. The combined intracardiac malformation or arrhythmia can be dealt with simultaneously.
