Comparable immediate success with multi-track versus Inoue; leaves open whether larger valve area improves long-term outcomes in rheumatic mitral stenosis.
Does the multi-track system improve clinical and echocardiographic outcomes compared to the Inoue system in patients with moderate to severe rheumatic mitral stenosis undergoing balloon mitral valvuloplasty?
Both Inoue and multi-track balloon systems are highly successful for mitral valvuloplasty, though the multi-track system yields a larger valve area and better commissurotomy at the cost of longer procedure and fluoroscopy times.
Oraby et al. (2011) studied this question.
