Situs Inversus - Report Of Twins

Dextrocardia with situs inversus (situs inversus totalis) is rare congenital anomaly which can be asymptomatic and compatible with normal life. Incidence is 1 in 10000. But in cases of situs inversus with levocardia association of congenital heart disease is high. We are presenting a pair of twins, born out of nonconsangunious marriage, from a primigravida mother, with an uneventful antenatal period, at 34 weeks 5 days of gestation. Both the twins did not required active resuscitation. On routine examination it was found that, both the twins had situs inverus and chest x ray, echocardiography and abdominal ultrasound was done, which confirmed the same. Our 1 twin was a case of situs inversus totalis (cardiac apex on right side) without any congenital heart disease and 2 twin was a case of situs inversus with levocardia (cardiac apex on left side) with complex congenital cyanotic heart disease. To conclude newborn babies should have a thorough physical examination after delivery before discharge to enable early diagnosis of congenital anomalies for appropriate referral. Though situs inversus in single neonate is well described, but we have not come across any case report in which both twins have situs inversus with or without dextrocardia, so we think the case is worth reporting.
