Why the study?
Does myectomy combined with mitral valve repair or replacement improve hemodynamic and functional parameters compared to myectomy alone in patients with HOCM?
Population
56 patients treated for hypertrophic obstructive cardiomyopathy (HOCM) between 1/84 and 6/91
Comparison
Myectomy in combination with mitral valve… vs Myectomy alone (Morrow technique)
Design
Cohort
Follow-up
mean 4.2 years

May support combined surgery for greater gradient reduction in HOCM; leaves open need for randomized outcome trials.
Does myectomy combined with mitral valve repair or replacement improve hemodynamic and functional parameters compared to myectomy alone in patients with HOCM?
Combining myectomy with mitral valve repair or replacement in HOCM patients may yield greater improvements in left-ventricular functional parameters and pressure gradients than myectomy alone.
Fritzsche et al. (1992) studied this question.
