Key result
Mitral valve repair in HOCM is linked to ~11% lower hospital mortality versus replacement.
Why the study?
The optimal surgical approach for patients with hypertrophic obstructive cardiomyopathy with concomitant mitral valve regurgitation has remained controversial.
Does mitral valve repair improve hospital mortality and length of stay compared to mitral valve replacement in patients with hypertrophic obstructive cardiomyopathy?
Population
1,255 patients with HOCM undergoing mitral valve surgery in the United States
Comparison

Design
Cohort study using Nationwide Inpatient Sample database

May favor repair over replacement in HOCM; leaves open selection bias and need for randomized confirmation.

Yes
Does mitral valve repair improve hospital mortality and length of stay compared to mitral valve replacement in patients with hypertrophic obstructive cardiomyopathy?
Absolute Event Rate: 0% vs 11.18%
p-value: p=<0.05
In patients with HOCM, mitral valve repair is underutilized despite being associated with significantly lower in-hospital mortality and shorter length of stay compared to replacement.
Vassileva et al. (2011) conducted a cohort in Hypertrophic Obstructive Cardiomyopathy (n=1,255). Mitral valve repair vs. Mitral valve replacement was evaluated on Hospital mortality (p=<0.05). Mitral valve repair in patients with hypertrophic obstructive cardiomyopathy was associated with lower hospital mortality (0.00% vs 11.18%, P<0.05) and shorter length of stay compared to replacement.
