Septal myectomy with a noncontact carbon dioxide laser for hypertrophic
cardiomyopathy is described. This technique results in improved
visualization of the septum as the laser beam is held outside the heart and
the resecting laser beam can always be clearly seen. We believe this
approach provides an improved method of septal myectomy in hypertrophic
cardiomyopathy.
