Number 09-18 Traumatic interventricular septal dissection
Case from: Qinyi Dai,MD; Zhaoqi Zhang,MD; Honghong Tie, PhD; Meng Li,PhD.
Movie 1 Movie 2
CMR findings: the SSFP cine long-axis 4-chamber (Movie 1) and mid-cavity short-axis (Movie 2) views demonstrated an interventricular septal dissection measuring 6.5x2.0x4.0cm in addition to a 2.5x3.5cm VSD causing a left to right shunt.
Figure legend: RA=right atrium, LA=left atrium, LV=left ventricle, RV=right ventricle
LGE imaging was also performed. The images are suboptimal but there is suggestion of LGE in the septum indicating myocardial necrosis (white arrow) (Figure 3).
Following the CMR, the patient underwent surgical VSD repair with a pericardial patch and direct suture with a good surgical result (Movie 3).
Perspective: Echocardiography has been widely used in traumatic cardiac injuries.However, MRI is more advantageous by precisely imaging the desired structures, hence enabling the surgeon to plan a definite operative strategy.
