Insights
Surgical septal myectomy treats obstructive hypertrophic cardiomyopathy. A novel combined transaortic and transapical approach was used for left ventricular enlargement in a complex hypertrophic cardiomyopathy case.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery
- Hypertrophic Cardiomyopathy Research
Background:
- Surgical septal myectomy is the gold standard for medically intractable obstructive hypertrophic cardiomyopathy.
- Extended transaortic septal myectomy effectively addresses subaortic obstruction.
- Transapical myectomy offers an alternative for specific hypertrophic cardiomyopathy phenotypes like apical hypertrophy.
Observation:
- A patient presented with diffuse hypertrophic cardiomyopathy, apical aneurysm, and mid-cavity obstruction.
- A combined transaortic and transapical dual surgical approach was employed.
- This dual approach aimed to achieve left ventricular enlargement.
Findings:
- The case demonstrates the feasibility of a combined transaortic and transapical approach.
- This technique was utilized for left ventricular enlargement in a complex hypertrophic cardiomyopathy case.
- The procedure addressed diffuse-type hypertrophic cardiomyopathy with apical aneurysm and mid-cavity obstruction.
Implications:
- This combined approach may expand surgical options for complex hypertrophic cardiomyopathy.
- It offers a potential solution for patients with challenging anatomical variations.
- Further research could validate this dual-approach for similar challenging cases.
Abstract:
Surgical septal myectomy is the preferred treatment option for patients with medically intractable obstructive hypertrophic cardiomyopathy. Extended transaortic septal myectomy is a widely performed surgical procedure for patients with subaortic obstruction. The transapical approach may provide an alternative surgical option in less common phenotypes, such as apical hypertrophy or long-segmental septal hypertrophy. In this report, we describe a case of a procedure performed to achieve left ventricular enlargement procedure using a combined transaortic and transapical dual approach in a patient with diffuse-type hypertrophic cardiomyopathy with apical aneurysm and mid-cavity obstruction.
