Insights
Surgical treatment for local hypertrophic cardiomyopathy (LHM) using myotomy-myectomy showed a 76.14% survival rate after five years. Patients with additional cardiac conditions experienced higher morbidity and mortality.
Area of Science:
- Cardiology
- Cardiac Surgery
Background:
- Local hypertrophic cardiomyopathy (LHM) presents unique surgical challenges.
- Surgical intervention aims to alleviate symptoms and improve quality of life.
Purpose of the Study:
- To evaluate the outcomes of surgical treatment for local hypertrophic cardiomyopathy (LHM).
- To compare outcomes between patients treated with myotomy-myectomy alone versus those requiring complementary procedures.
Main Methods:
- Surgical treatment involving myotomy-myectomy was performed on 23 patients with LHM.
- Patients were divided into two groups: Group I (myotomy-myectomy alone) and Group II (myotomy-myectomy with complementary cardiac procedures).
Main Results:
- Fifteen patients (Group I) underwent myotomy-myectomy alone.
- Eight patients (Group II) required additional procedures, experiencing significantly higher morbidity and mortality.
- A five-year follow-up revealed an overall survival rate of 76.14%.
Conclusions:
- Myotomy-myectomy is a viable surgical option for local hypertrophic cardiomyopathy (LHM).
- Patients with coexisting cardiac conditions face increased risks, necessitating careful pre-operative assessment and management.
- Long-term survival is achievable, but outcomes are influenced by disease complexity.
Abstract:
We report the surgical treatment of 23 patients with local hypertrophic cardiomyopathy (LHM). Fifteen patients, group I (65.3%), with LHM were treated by myotomy-myectomy alone. Eight patients, group II (34.7%), with LHM and other cardiac disease, was treated by myotomy-myectomy and complementary procedure (mitral or aortic replacement, correction of congenital malformation). This group II had the major morbidity and mortality. Five years follow up had a 76.14% survival.
