[Criteria for the selection of patients with a single heart ventricle for anatomical correction]
Insights
Assessing solitary ventricle of the heart (SVH) patients reveals universal myocardial dysfunction. Anatomical correction is feasible only if future ventricles demonstrate adequate ejection fraction, a criterion met by few.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Solitary ventricle of the heart (SVH) presents complex anatomical and functional challenges.
- Myocardial function in SVH patients is often compromised, impacting treatment strategies.
Abstract:
The work deals with study of the functional condition of the myocardium in 34 patients with a solitary ventricle of the heart (SVH). The regional function of the myocardium was disturbed in all patients; the degree of the disturbance was determined by the anatomical variant of the SVH and was characterized by different distribution of the hypofunctioning segments in the ventricular myocardium. In view of that, to solve the problem of the possibility of accomplishing anatomical correction, the regional function in the zones of the future (after septation) ventricles must be evaluated. Radical correction may be performed with the least degree of risk in patients in whom the ejection fraction in each of the new ventricles will be greater than or equal to 55%. In the group of 17 patients only 5 conformed to this criterion.
