4D Printing of Bioinspired Absorbable Left Atrial Appendage Occluders: A Proof-of-Concept Study.
ACS Applied Materials and Interfaces, 2021 The significant mismatch of mechanical properties between the implanted medical device and biological tissue is prone to cause wear and even perforation. In addition, the limited biocompatibility and nondegradability of commercial Nitinol-based occlusion

Left Atrial Appendage Aneurysm [PDF]
The Annals of Thoracic Surgery, 2016 Left atrial appendage aneurysms (LAAA) are extremely rare. This condition is usually diagnosed incidentally or after the occurrence of thrombotic events or cardiac tachyarrhythmias in the second to fourth decades of life. It can predispose to hazardous adverse events, including atrial fibrillation, myocardial infarction, and systemic thromboembolism ...

Left atrial appendage aneurysm [PDF]
Interactive CardioVascular and Thoracic Surgery, 2019 Abstract Left atrial appendage aneurysm is an infrequent abnormality presenting as atrial tachyarrhythmias, progressive dyspnoea, atypical chest pain and systemic thromboembolism. Surgical excision is considered to prevent fatal complications, even in asymptomatic cases. We describe the case of a 44-year-old woman with a history of acute
