“…The cardiovascular defects found in the lecanosomatopagus conjoined twins we studied were similar to those described in the majority of thoracopagus twins [2,3]. The feasibility of a surgical separation of thoracopagus twins strongly depends on the extent of the conjunction of the heart and the severity of the present cardiac malforma tions; for this reason the anatomy of the car diovascular system is first investigated in their evaluation [4].…”

Female conjoined twins were delivered after 42 weeks’ gestation, but they died within a few minutes of birth. They were dicephalus, dibrachius and dipus conjoined twins with two separate spines and fusion of the trunk and the pelvis. The pericardial sac was common, and the heart was a single structure. The atrial complex was a common chamber with an attempt at division into two parts by a circular ridge of tissue; the ventricular complex was formed by three chambers which were all communicating between each other in the superior margin of their muscular interventricular septum.

“…This latter condition is often associated with mul tiple congenital cardiac abnormalities. Of 5 pairs of conjoined twins, catheterized by Izukawa et al [5], 2 pairs each were found in groups A and B. and one pair in group C. The infant that we have described clearly fits group C.…”

“…One of the aims of cardiac evaluation is to classify these infants into the following three groups [5], in order of decreasing compatibil ity with life and of diminishing possibility of surgery: (A) Single pericardium with 2 nor mal hearts: (B) conjoined atria with 2 sepa rate ventricles, and. (C) fused ventricles.…”

Thoracopagus conjoined twins were delivered at 31 weeks gestation by cesarean section. Although there was a single heart, the possibility of salvaging one twin only was contemplated. Echocardiography revealed an A-V canal and suspected transposition of the great vessels. To determine the possibility of surgery, cardiac catheterization was performed to rule out other congenital cardiac malformations incompatible with life, and also to delineate the exact anatomy of the great vessels of the heart. Unfortunately, complex congenital abnormalities were found, thus excluding the possibility of surgery. Newly delivered conjoined twins should be regarded as potentially correctable and should be promptly investigated while they are yet in good clinical condition.

“…Over the last two decades, several modalities have become available in addition to angiography in determining the degree of cardiac involvement, including prenatal and postnatal echocardiography and MRI. There have only been isolated case reports of angiography as a diagnostic tool in conjoined twins, prompting us to report our experience [5,[12][13][14][15][16].…”

Over the last two decades, surgical separation of thoracopagus conjoined twins has become increasingly feasible. Delineation of the degree of cardiac involvement is essential to establish the feasibility of surgical separation. We describe our experience of cardiac catheterization both in the diagnosis and management of nine sets of thoracopagus twins who presented to a single center over three decades and discuss its role in conjunction with other modern diagnostic modalities.
