BACKGROUND

Myocarditis and pericarditis are inflammatory conditions of the heart commonly due to viral or autoimmune etiologies. Human CMV represents one of the leading causes of congenital infections worldwide. There is limited data regarding the cardiac function of fetuses and infants with CMV.

OBJECTIVE

To provide insight regarding the presence of myocardial involvement in fetuses and infants with CMV infection.

PATIENTS & METHODS

Up to 100 fetuses with suspected CMV infection will be enrolled during a 3 years period. Patients will undergo detailed US examinations including dedicated neurosonography and echocardiography starting at the time of the first referral and every 3-4 weeks until delivery and at the 2-7th day birth. Cardiac scans of fifty pregnant women and the healthy women from the group will serve as controls

EXPECTED RESULTS

Subtle myocardial deformation abnormalities are expected to be commonly found in fetuses and infants with CMV infection.

CONCLUSIONS

The findings of this present study will underscore the need for cardiac screening of fetuses and infants with congenital CMV infection, with long-term follow-up to document the natural history and disease burden of CMV in this population.

Inclusion Criteria:

1. Patients referred because of suspected CMV IUI as demonstrated by seroconversion during pregnancy or during the 3 months that precede LMP or
2. Patients referred because of suspected CMV IUI based on the presence borderline CMV serology
3. US signs indicative of intrauterine CMV infection (CNS and non CNS involvement).

Exclusion Criteria:

1. Multifetal pregnancy.
2. Pregnant women planning to deliver elsewhere who are offered yet refuse to participate in the postnatal investigation following discharge from the hospital.
3. Patients will be excluded if they had clinical heart failure, as defined by the New York Heart Association classification (NYHA, class II-IV) (Criteria committee of NYHA 1994), a history of cardiovascular disease or chronic renal insufficiency.
