Conclusion
Optimal management of the very rare PA haemangiomas is conflicting.
While conservative management with watchful waiting due to their benign
nature has been advocated [1], a much radical approach with
resection of the mass on cardiopulmonary bypass and incorpoarating part
of the PA wall has been employed by others [2]. We believe that
surgical excision is essential for the purposes of diagnosis and
prevention of complications but this can be safely achieved on the
beating heart with similar completeness.
