Post-valvulotomy right ventricular pressure below 100 mm Hg was associated with halted enlargement; leaves open whether this threshold should guide intervention.
Does valvulotomy halt cardiac enlargement in patients with valvular pulmonic stenosis with an intact ventricular septum?
In patients undergoing valvulotomy for pulmonic stenosis, achieving a postoperative right ventricular pressure below 100 mm Hg is associated with the cessation of cardiac enlargement.
Hosier et al. (1956) studied this question.
