Case in brief
A symptomatic patient with severe left ventricular outflow tract obstruction and systolic anterior motion of the mitral valve underwent a totally endoscopic transaortic septal myectomy. Preoperative imaging revealed marked asymmetric septal hypertrophy and significant outflow tract gradient. The procedure utilized three-dimensional endoscopic visualization and resulted in intraoperative resolution of systolic anterior motion and a marked reduction in outflow tract obstruction, with postoperative echocardiography showing preserved ventricular function.
What made this case unusual
The case demonstrates the successful application of a totally endoscopic approach for septal myectomy, which is less common compared to traditional surgical methods.
Diagnostic / clinical pearl
Clinicians should consider the feasibility of totally endoscopic techniques for septal myectomy in patients with hypertrophic obstructive cardiomyopathy who do not respond to medical therapy.
Why it matters
This case underscores the potential benefits of non-sternotomy techniques in cardiac surgery, which may lead to improved recovery and outcomes for patients.
