Journal Title: Journal of Air Force Medical University - Year 2023, Vol 44, Issue 8
Abstract
Objective To analyze the cardiac CT angiography ( CTA ) imaging and clinical characteristics in patients with false aneurysm of the membranous septum ( FAMS) with ventricular septal defect ( VSD). Methods The cardiac CTA imaging data of 73 patients with FAMS combined with VSD diagnosed in Xijing Hospital, Air Force Medical University from January 2010 to January 2022 were retrospectively analyzed, and the cardiac CTA imaging characteristics of FAMS, combined cardiovascular malformations and complications were recorded. Results Among the 73 patients with FAMS, cauliflower type was the most common (58. 9% , 43 / 73), and often combined with more than 2 VSDs, followed by funnel type ( 26. 0% , 19 / 73 ), sack type ( 12. 3% , 9 / 73 ), and siphon type ( 2. 7% , 2 / 73 ) . Seventeen patients (23. 3% , 17 / 73) with FAMS were combined with cardiovascular malformations. The common cardiovascular malformations were coarctation of the aorta (6. 8% , 5 / 73) and atrial septal defect (5. 5% , 4 / 73). The secondary cardiac changes were mainly right atrial enlargement and tricuspid regurgitation, which were more common in patients with sack type FAMS than in the other three types ( P < 0. 05) . Conclusion Cauliflower type is the most common type in patients with FAMS combined with VSD. Cauliflower type FAMS is often combined with multiple VSDs. FAMS patients are mainly complicated with cardiovascular malformations such as coarctation of the aorta and atrial septal defect. The secondary cardiac changes were mainly right atrial enlargement and medium to massive tricuspid regurgitation, especially in patients with sack type FAMS.
