The introduction of the Y(ang)-technique for aortic root enlargement has sparked a renewed interest in annular and root enlargement procedures world-wide. In order to execute these procedures proficiently however, it’s important to understand the complex three-dimensional structure of the aortic root and left ventricular outflow tract, and also be familiar with the different enlargement techniques. Herein, we are providing a description of the aortic root anatomy and the most commonly utilized root enlargement procedures. This should facilitate clinical decision making and guidance of patients towards the most appropriate procedure, which should not only treat the patients’ acute symptoms, but should also set the patient up for potentially needed future procedures and respective life-time management of aortic valve disease.
