Paediatric subvalvular aortic stenosis: a systematic review and meta-analysis of natural history and surgical outcome.
Etnel JR, Takkenberg JJ, Spaans LG, Bogers AJ, Helbing WA. Etnel JR, et al. Eur J Cardiothorac Surg. 2015 Aug;48(2):212-20. doi: 10.1093/ejcts/ezu423. Epub 2014 Nov 5. Eur J Cardiothorac Surg. 2015. PMID: 25378361 Review.
Higher LVOT gradient and the presence of aortic regurgitation (AR) were identified as the foremost independent predictors of a worse outcome. Valve-to-membrane distance was also found to be associated with prognosis, although the results were contradictory. ...

Excluding patients with previous surgical or balloon aortic valvuloplasty, a higher maximal Doppler gradient was an independent risk factor for moderate to severe AR (OR for peak gradient > or =50 mm Hg 10.8, p = 0.001). Independent predictors of low-risk patients (none …
