Severe pulmonary valvar insufficiency should be aggressively treated

Extract

My role in the debate between myself and Bill Gaynor is to substantiate the notion that severe pulmonary valvar insufficiency should be treated in aggressive fashion. This gives me few problems. At Children's Memorial Hospital in Chicago, we have a long tradition of favouring early insertion of new pulmonary valves in patients with significant pulmonary valvar insufficiency following repair of tetralogy of Fallot. Our results with this strategy in the current era were first presented in 1986 at the Western Thoracic Surgical Association.¹ At that time, we had inserted pulmonary valves late following repair of tetralogy of Fallot in 42 patients. We postulated that early control of pulmonary insufficiency may prevent long-term deterioration in right ventricular function. The fact that this is a controversial issue became immediately apparent during the discussion of our presentation. Dr. Frank Spencer, from New York, stated “I would completely disagree with the concept of electively inserting a porcine valve in a child on the basis of haemodynamic data. I fear that the approach recommended in this presentation is probably treating one disease by creating a worse one.”
