Abstract
OBJECTIVES
Patients with unoperated functional single ventricle (FSV) rarely survive into adulthood with good functional status and there are few reports about surgical results of adult patients with FSV. This study retrospectively reviews our experience with surgery in adult patients with FSV.
METHODS
From January 2008 to September 2017, 65 adult patients with FSV underwent surgery in our hospital. Twenty underwent Blalock-Taussig shunt or bidirectional Glenn procedures in other hospitals prior, and four were lost to follow-up. Finally, 41 patients were included in this study.
RESULTS
The early postoperative mortality was 7.3% (3/41). Postoperative systemic arterial oxygen saturation (SpO2 , 83.7% ± 4.8%) was significantly higher than preoperative SpO2 (77.9% ± 10.1%, P < .01). The mean follow-up time was 3.9 ± 3.1 years (range 1-11 years). There was only one case of late mortality and massive hemoptysis was the cause of death. Right ventricular morphology and severe atrioventricular valve regurgitation (AVVR) were the risk factors of postoperative death for patients with pulmonary stenosis(PS). There was no death case in patients who received Fontan procedure. In a follow-up, we found the grade of AVVR was reduced and the grade of heart function (New York Heart Association) was improved.
CONCLUSIONS
Adult patients with FSV can also undergo surgery. The mortality was acceptable and late results were satisfactory. After surgery, oxygen saturations increased, grades of AVVR decreased and the heart functions improved. Right ventricular morphology and severe AVVR were risk factors for patients with PS.
