Abstract |
Eight neonates with transient tricuspid insufficiency are presented which was confirmed clinical and two dimensional echocardiographic assessment.
We found that two dimensional Doppler echocardiography was very useful in the detection of transient tricuspid insufficiency during neonatal age as noninvasive method.
Transient tricuspid insufficiency is a clinical disorder in the newborn period caused by myocardial dysfunction, secondary to asphyxia with or without hypoglycemia and associated with right ventricular overloading caused by pulmonary hypertention.
The clinicla diagnosis was based on a history of perinatal distress, distinctive murmur, ECG changes, biochemical abnormalities and myocardial imaging.
1) The sex ratio of TT1 was 1:1
2) The average gestational age was 34 weeks and mean body weight was 2.606 Kg, respectably.
3) Major symptoms were dyspnea, cyanosis, and tachypnea.
4) Tricuspid regurgitation was detected from the 1st day to the 4th day of the life and was improved from the 7th day to 30th day of the life.
5) The peak velocity through tricuspid valve ranged from the 2.7m/sec to 4.0m/sec and the estimated right ventricular pressure ranged from 39mmHg to 74mmHg.
6) Associated diseases were neonatal hyperbilirubinemia(100%), prematurity(87.5%), atrial right to left shunt(87.5%), patent ductus arteiosus(75%), hyaline membrane disease(25%), and transient tachypnea of newborn(12.5%). |
