Key result
Fenestrated closure of an atrial septal defect successfully managed left ventricular diastolic dysfunction in an infant with concurrent hypertrophic cardiomyopathy.
Why the study?
Left ventricular diastolic dysfunction is associated with poor prognosis in patients with hypertrophic cardiomyopathy and CHD.
Fenestrated closure of an atrial septal defect was successfully used to manage left ventricular diastolic dysfunction in an infant with hypertrophic cardiomyopathy.
Fenestrated ASD closure may relieve LV diastolic dysfunction in infant HCM; hypothesis-generating and requires validation before broader use.
Left ventricular diastolic dysfunction is associated with poor prognosis in patients with hypertrophic cardiomyopathy and CHD. We report the case of an infant concomitant with hypertrophic cardiomyopathy, an atrial septal defect, and left ventricular diastolic dysfunction, who was successfully managed with fenestrated closure of the atrial septal defect.
