Abstract:
Objective To study the value of the application of 320-row detector dynamic volume CT in diagnosis of complicated congenital heart diseases(CCHD).Methods Datas of 43 cases with CCHD,who examined by ECC-gated 320-row CT angiography (CTA)as preoperative examinations were collected.All the CT data were processed by combined application of multi-imaging post-processing technique to show the anatomic malformation based on segmental analysis,and were compared with the transthoracic ech-ocardiography (TTE )and surgical results .Results 1 97 various malformations were found in 43 cases and proved by operation, among which there were 87 intracardiac malformations,the diagnostic accuracy with CTA and TTE were 86.2%,89.7%,and there was no obvious difference between them(P >0.05 ).1 10 extracardiac malformations (including connection malformations between heart and vessels,extracardiovascular malformation,bronchial or other nonvascular structure malformation)were found ,the accura-cy with CTA and TTE were 91.8% and 76.4%,the former was superior to latter (P <0.05)Conclusion 320-row detector dynamic volume CT in diagnosis of CCHD has very important meaning and practical application value,should be used as the significant choice for clinical diagnosis of CCHD.
