A sinus of Valsalva aneurysm (SOVA) can be a congenital (present at birth) or acquired heart defect. If not treated quickly, it can form a hole called an aortico-left ventricular tunnel. Our Nemours Cardiac Center team has the experience and advanced pediatric imaging needed to diagnose and surgically repair rare heart defects like SOVA. If your child has congenital heart disease, our board-certified, fellowship-trained pediatric cardiologists and heart surgeons are here to answer your questions, ease your concerns and provide the latest treatment options.
