Surgical Repair for Primary Tricuspid Valve Disease: Individualized Surgical Planning With 3-Dimensional Printing

Primary tricuspid valve (TV) disease is rare and associated with high operative mortality. Optimal surgical planning requires a precise understanding of the pathological features; however, detailed imaging of the TV can be challenging. We present 4 cases of primary TV disease where 3-dimensional printing was pivotal to operative planning and success. (Level of Difficulty: Advanced.).
