Fig. 4From: Assessment of degradability and endothelialization of modified poly L-lactic acid (PLLA) atrial septal defect (ASD) occluders over time in vivoImaging examination of pigs implanted with PLLA occluders. (A) The PLLA occluder was released through the X-ray position of seven platinum-iridium markers; (B) X-ray after release of PLLA occluder; (C) Ultrasonic morphology and position after release of PLLA occluder. Red arrows indicated the PLLA ASD occluder. PLLA: poly L-lactide. ASD: atrial septal defectBack to article page
