Prior to 1970, most patients with tricuspid atresia (TA) and reduced
pulmonary blood flow were palliated by means of a systemic to pulmonary
artery shunt (SPAS). In Birmingham between 1967 and 1988, 19 patients with
TA (aged 16 days to 23 years, mean 3.8 years) have undergone side- to-side
cavopulmonary anastomosis (CPA) with preservation of pulmonary artery
continuity. One had undergone a previous right Blalock-Taussig shunt and in
1 patient with left and right SVCs, bilateral CPAs were performed. Nine
patients were less than 1 year old at the time of operation. There were no
operative deaths. One late death occurred due to pneumonia. Immediate
clinical improvement occurred in all cases. Six symptomatic patients
subsequently required further surgery (mean interval between operations 8.9
years, range 4.6-14.2 years). The remaining 12 patients have recently been
reviewed. Mean follow-up was 9.5 years (range 5 weeks to 21 years).
Exercise tolerance remains good (9 in NY-HA Class 1 or 2) and resting
transcutaneous oxygen saturations are higher (mean 85%, range 70%-89%)
compared with preoperative values (P less than 0.01). In small children,
CPA avoids the complications of SPAS and, in some patients, may itself
achieve adequate long-term definitive palliation.
