Understanding the morphological features and mechanisms of anatomic, dynamic, and mixed forms of subaortic left ventricular outflow tract obstruction is essential for planning surgical repair.
Subaortic narrowing leading to left ventricular outflow tract obstruction (LVOTO) is a significant pathology that may be encountered pre- or postoperatively in both acquired or congenital cardiac disease. Through a review of the morphological features and mechanisms in the different clinical situations, the anatomic, dynamic and mixed forms of subaortic obstruction are emphasized. Knowledge of the substrate of LVOTO, its physiopathology and natural history allows to plan accordingly the surgical repair and the postoperative management.
Radermeckei et al. (Sat,) conducted a review in Left ventricular outflow tract obstruction (LVOTO). Understanding the morphological features and mechanisms of anatomic, dynamic, and mixed forms of subaortic left ventricular outflow tract obstruction is essential for planning surgical repair.
