Insights
Fabry's disease can cause cardiac issues mimicking hypertrophic cardiomyopathy. Extended septal myectomy may be a viable treatment for persistent left ventricular outflow tract obstruction despite enzyme replacement therapy.
Area of Science:
- Cardiology
- Genetics
- Metabolic Disorders
Background:
- Fabry's disease is a genetic disorder with cardiac manifestations that can resemble hypertrophic cardiomyopathy.
- Left ventricular outflow tract (LVOT) obstruction is a significant cardiac complication in Fabry's disease.
Observation:
- Distinguishing Fabry's disease from hypertrophic cardiomyopathy is crucial for appropriate treatment.
- Enzyme replacement therapy (ERT) is the standard treatment for Fabry's disease.
- Some patients with Fabry's disease experience persistent LVOT obstruction even after adequate ERT.
Findings:
- This study presents two cases of extended septal myectomy in patients with Fabry's disease.
- Septal myectomy was considered for patients with refractory LVOT obstruction secondary to Fabry's disease.
Implications:
- Extended septal myectomy can be a therapeutic option for managing persistent LVOT obstruction in Fabry's disease.
- These findings highlight the importance of considering surgical intervention when medical management fails.
- Further research is needed to evaluate the long-term efficacy and safety of septal myectomy in Fabry's disease patients.
Abstract:
Fabry's disease has cardiac manifestations that may mimic hypertrophic cardiomyopathy, including left ventricular outflow tract (LVOT) obstruction. It is important to distinguish hypertrophic cardiomyopathy from Fabry's disease, which can be treated with enzyme replacement therapy (ERT). However, after adequate ERT, some patients have no resolution of cardiac symptoms; thus, septal myectomy might be considered. We present 2 cases of extended septal myectomy in patients with LVOT obstruction secondary to Fabry's disease.
