Summary: This week we enter into the world of cardiac morphology and speak with Professor Leo Lopez of Stanford University about a recent work he wrote with the International Society for Nomenclature of Pediatric and Congenital Heart Disease regarding proper nomenclature for VSD's. Is it defect geography or borders that are most important in naming these structures? How was agreement forged between such disparate super-hero experts in cardiovascular medicine and congenital heart disease? Is Dr. Lopez using these designations at the present time? What's next for the nomenclature group? Dr. Lopez shares his insights this week and, as a special treat, also sings as the musical coda to today's program. A very special treat indeed! doi: 10.1016/j.athoracsur.2018.06.020
