Multiplanar Reformations

The possibility of using multiplanar reformations oriented on the axis of heart in diagnosing the common arterial trunk with X-ray computed tomography is substantiated. Examination data of 140 patients aged 1-19 days of life, 3030-3890 g body weight with conotruncal congenital heart diseases was analyzed, and common arterial trunk was detected in 7 patients (4 - boys, 3 - girls). In 5 (72%) patients, it developed mainly from the morphological right ventricle, 1 (14%) - completely from the morphologically right ventricle, and 1 more (14%) - evenly located above the ventricles. In four (57%) cases, the trunk valve had three leaflets, in two (28,5%) cases - two, in one (14,5%) case - four. All the patients had mitral-semilunar fibrous prolongation, intraventricular septal defects, doubled coronary arteries system, and the pulmonary arteries had their origin from ascendant part of common trunk. Pulmonary arteries had also their own common trunk in 4 (57%) cases, separate estuary in 3 (43%) cases. Aortic arc abnormalities included dextral aortic arc (2 cases), discontinuity of aortic arc (1 case), discontinuity of fourth aortic arc with persistence of fifth left aortic arc (2 cases). In general, computed tomographic angiocardiography heart-axis-oriented multiplanar reformations permit full and correct assessment of heart and main vessels, which is important for surgical treatment planning in congenital heart diseases.

Operative Evaluation

Background: Multi-slice computed tomography (MSCT) plays an important role in clinical practice in assessing post-operative patients with complex CHD when echocardiography is not contributory.  Despite the great capabilities of MR imaging for anatomic and functional assessment of the heart, it is time-consuming and may require a lengthy period of patient sedation; hence its use in seriously ill or uncooperative patients is often limited. CT has the advantages of widespread availability and short acquisition times. It is imperative for a radiologist to be aware of various palliative as well as corrective procedures and their various imaging findings. Aim of this article is to demonstrate and make one aware of various checklists and imaging findings in paediatric patients who have undergone various shunts and grafts at our tertiary cardiac care centre, their immediate as well as long term complications.Methods: We studied a total of 100 paediatric patients (<12 years old), who had undergone some sort of palliative or corrective shunt or graft placement, on MSCT during the period 2014 to 2018 at our tertiary cardiac care centre.Results: We try to outline details of various shunts and grafts used in congenital heart diseases correction, MSCT technique and imaging appearances and appearances of abnormal post-operative findings.Conclusions: Advances in computed tomography (CT) scanners and electrocardiographic gating techniques have resulted in superior image quality of the aorta and pulmonary arteries for evaluating postoperative congenital heart disease. MSCT is an excellent non-invasive modality for post-operative evaluation of various shunts and grafts.

In Pregnancy

Congenital Heart Diseases (CHD) lead to various changes in the normal mechanisms of hemodynamics. Pregnancy in women with CHDs is rare. Double Outlet Right Ventricle (DORV) is a rare disorder, in which both the aorta and the pulmonary artery arise from the right ventricle. We present a case of a thirty-year-old pregnant woman who presented to us with 22 weeks of amenorrhea. She had DORV with VSD, which was undiagnosed till she came to our hospital. Double Outlet Right Ventricle (DORV) is a rare congenital heart disease. Pregnancy in a patient with DORV needs early diagnosis and a stepwise multidisciplinary approach for successful outcomes.

AbstractSo as to understand better the pathogenesis of enlargement or hypoplasia of pulmonary arteries in congenital heart disease, we studied the dimensions of the pulmonary arteries in 74 fetuses with congenital heart disease induced by administration of bis-diamine to pregnant rats. The congenital malformations induced included 12 with large ventricular septal defect, 17 with tetralogy of Fallot, 15 with tetralogy together with severe valvar pulmonary stenosis and absence of the arterial duct, 17 with tetralogy with absent pulmonary valve syndrome and absence of the arterial duct, and 13 with common arterial trunk with a confluent segment supplying the pulmonary arteries. For comparison, 16 fetuses of the same gestational age with normal hearts were studied. After rapid whole-body freezing on the 21st day of gestation, the fetuses were studied by means of serial cross-sectional photographs of the thorax. The diameter of the right pulmonary artery of the fetus was of comparable dimensions in the normal hearts (480±10 µm) (mean±SEM), those with ventricular septal defects (470±10 µm), common arterial trunk (520±20 µm), and tetralogy of Fallot (500±10 µm). These findings suggest that the commonly observed enlargement of the right pulmonary artery in patients with ventricular septal defect and common arterial trunk, and hypoplasia of the right pulmonary artery in tetralogy of Fallot, occur postnatally in response to abnormal postnatal pulmonary blood flow.
