Fig. 3From: Assessment of degradability and endothelialization of modified poly L-lactic acid (PLLA) atrial septal defect (ASD) occluders over time in vivoSteps of pigs implanted with PLLA occluders. (A) Pigs were given tracheal intubation under general anesthesia; the red arrow indicated the atrial septum. (B) Atrial septal puncture; the red arrow indicated the Left atrium. (C, D) The balloon dilates the atrial septum; the red arrow indicated the atrial septum. (E) Left atrial angiography; the red arrow indicated the Left atrium. (F) Ultrasonic measurement of atrial septal defect; the red arrow indicated the ASD. PLLA: poly L-lactide. ASD: atrial septal defectBack to article page
