Key result
Doppler blood flow and tissue echocardiography detected marked elevation of left ventricular end-diastolic pressure and abnormal myocardial relaxation in an infant who died suddenly at 13 months.
Case Report (n=1)
Idiopathic restrictive cardiomyopathy in infants can present with severe diastolic dysfunction and lead to sudden death even in the absence of overt heart failure.
Alerts clinicians to sudden death risk in infants with restrictive cardiomyopathy despite absent failure; leaves open need for prospective validation.
We describe the clinical features of idiopathic restrictive cardiomyopathy in a female infant. A marked elevation of left ventricular end-diastolic pressure, and profoundly abnormal myocardial relaxation, were detected with the use of Doppler blood flow echocardiography, coupled with the relatively new technique of Doppler tissue echocardiography. There was no clinical evidence of ongoing heart failure, but she had signs of myocardial ischaemia, and unfortunately died suddenly at the age of 13 months.

Palka et al. (2003) conducted a case report in Idiopathic restrictive cardiomyopathy (n=1). Doppler blood flow and tissue echocardiography was evaluated. Doppler blood flow and tissue echocardiography detected marked elevation of left ventricular end-diastolic pressure and abnormal myocardial relaxation in an infant who died suddenly at 13 months.
