Time series of images from human heart 277. This series shows tricuspid valve closure from the right ventricle (a) and right atria (b) through slightly greater than one cardiac cycle. In series B, the septal leaflet can be seen toward the bottom left of the images. Images are displayed 1/15th per second apart in time. Panel C displays ice formation on the distal portion of a cryoballoon ablation catheter (Artic Front, Medtronic PLC, Minneapolis, MN, USA) as seen from within the pulmonary vein. The images are spaced 20 s, 1, 2, and 3 min from the start of ablation cooling
