Learning objectives
- To illustrate the radiological imaging findings of main surgical repair procedures
- To understand the basic physiological background of these procedures
Background
Congenital heart diseases (CHD) are remarkable health problems that can lead to various problems, even mortality. A variety of complex surgical procedures have been described to correct impaired physiology resulted from these anomalies. After these procedures, patients are followed-up with different imaging modalities to assess the treatment outcome. Thus, radiologists need to be familiar with postoperative imaging findings of cardiac surgical procedures for accurate and effective reporting.
This article is designed to illustrate the imaging findings of the selected surgical procedures and to understand the...
Findings and procedure details
1. Palliative procedures
a. Blalock-Taussig (BT) shunt:
BT shunt is a type of systemic-to-pulmonary artery shunt performed to increase the oxygen-poor blood delivery to the pulmonary artery in cyanotic heart diseases. There are two types of BT shunt as classic and modified. In the classic BT shunt, a connection between the subclavian artery and the ipsilateral pulmonary artery is made by end-to-side anastomosis. However, in the modified BT shunt, to better preserve the blood flow to the ipsilateral arm, a prosthetic graft is interposed between...
Conclusion
A radiologist must be familiar with the complex anatomy of CHD and the imaging findings of surgical procedures to avoid misinterpretation and inaccurate reporting.
