Why the study?
Does re-do surgery compared to primary operation associate with a higher prevalence of aortic regurgitation in patients with subaortic stenosis?
Does re-do surgery compared to primary operation associate with a higher prevalence of aortic regurgitation in patients with subaortic stenosis?
Aortic valve regurgitation is significantly more prevalent in patients requiring re-do surgery for recurrent subaortic stenosis, suggesting that adding myectomy is preferable to isolated shelf resection.
No takes yet. Share an insight, caveat, or question.
Re-do surgery for subaortic stenosis was associated with higher moderate-severe AR; leaves open whether adding myectomy during primary resection reduces recurrence or AR progression.
Barkhordarian et al. (2006) studied this question.
