VSD with prolapsed RCC of aortic valve

The right coronary cusp of the aortic valve is seen prolapsing across the VSD and into the right ventricle. Note that the cusp is unusually elongated and more restricted in its motion when compared with the left coronary cusp.

VSD: ventricular septal defect; RCC: right coronary cusp; RV: right ventricle; LV: left ventricle; AO: aorta; MV: mitral valve; LA: left atrium; arrow: VSD.
