The preferred method is balloon valvotomy and this should be recommended once echocardiography reveals a significant gradient (> 30 mmHg at rest) and signs of abnormal right ventricular function (abnormal septal motion, RV dilatation). Complications of valvotomy include significant pulmonary regurgitation, but severe regurgitation is uncommon. Successful valvotomy is associated with an excellent long-term prognosis. Infrequent follow-up by transthoracic echo is appropriate to monitor for restenosis or regurgitation. Patients do not need to restrict their sporting activities, and pregnancy is usually managed routinely unless there is severe untreated stenosis. Atrial arrhythmias can complicate cases where right ventricular failure has supervened
