Intracardiac echocardiography, showing distorted intracardiac anatomy. The oval shape in the center of the screen is the non-coronary sinus of Valsalva. Below is the right atrium at the bottom of which the transseptal needle is clearly visible. The prominent muscular structure in the left-hand part of the image is the terminal crest. The membrane of the oval fossa, adjacent to the right-hand part of the non-coronary aortic sinus shows bidirectional flapping motion. During the atrial contraction the cavity of the left atrium virtually disappears.
