A series of 25 patients with hypertrophic obstructive cardiomyopathy,
isolated or associated with minor anomalies, were operated upon using a
modified Morrow's procedure. The indication for operation was based on
either the presence of severe symptoms despite treatment with beta-
blocking agents, or a significant peak gradient of over 50 mmHg even in
asymptomatic patients. All patients survived and none was lost to
follow-up. Long-term results were evaluated with 2-dimensional
echocardiography. Surgical versus pharmacological treatment is discussed,
with particular consideration given to paediatric patients.
