1CMR图像,上行为短轴位,下行为四腔心位。A、D为正常对照组:女性,26岁;B、E为IVS无形变组:女性,65岁,mPAP=44 mmHg,IVS未发生形变;C、F为IVS有形变组:女性,31岁,mPAP=54 mmHg,RV明显增大,IVS形变并向左偏。
CMR imaging. Upper row is short axis image, and lower row is four-chamber image. Images A and D are in control group: female, 26 years old. Images B and E are in non-deformation group: female, 65 years old, mPAP=44 mmHg, IVS no deformation. Images C and F are in deformation group: female, 31 years old, mPAP=54 mmHg, RV enlarged significantly, IVS deformation.
