ABSTRACT

OBJECTIVES: Data on long-term outcomes after surgical repair of pulmonary valve stenosis are limited. This study evaluated survival, clinical outcomes and quality of life (QoL) after surgery during childhood.

METHODS: Single centre, longitudinal cohort study evaluating consecutive patients with pulmonary valve stenosis who underwent surgical repair between 1968-1980 and were evaluated every decade since 1990.

RESULTS: Of the original cohort of 89 operated patients, 11 died (12%), including 2 who died within 30 days postsurgery (2%), and 7 (8%) were lost to follow-up. Survival at 50 years follow-up was 87%, which was not significantly different from the GDP. Of the remaining 71 survivors, 32 refrained earlier from participating in this cohort study, leaving 39 eligible, of whom 34 (87%) participated again (50% male, median age 48 years) with a median follow-up of 45 (range 40-52) years. Event-free survival was 50%, with supraventricular tachycardia (14%) and reintervention (13%) being the most frequent events, although less frequently in the last 10 years. At last follow-up, biventricular function was preserved in most patients. Reduced right and left ventricular ejection fraction (EF) was found in 33% and 13%, respectively. Exercise capacity and maximum rate of oxygen consumption were mildly impaired in 14% and 32% of patients. Patients who underwent an infundibulectomy during initial surgery were significantly more likely to undergo reintervention (HR=8.32, p=0.003). Patient-reported QoL scores remained stable over time and consistently exceeded those of the age-matched GDP.

CONCLUSION: Fifty-year survival after surgery for pulmonary valve stenosis was excellent and comparable to the GDP. Most patients maintained preserved ventricular function, functional capacity and excellent QoL. Routine lifelong follow-up may not be necessary for all patients, but should be considered for those who underwent an infundibulectomy or have residual lesions.
