CIC 2021| SHSMA MemoLofort LAA Closure Occluder Made Its Debut in Chang’an

Professor Hu Haibo presented Identification and Prevention Strategies of PFO/ASD and Atrial Fibrillation-related Stroke, made clear that non-valvular atrial fibrillation and patent foramen ovale formed risky factors for ischemic stroke, PFO/ASD integrated atrial fibrillation tended to show a higher incidence of stroke, and more attention should be paid to stroke prevention. For now, safety and effectiveness of PFO and LAA interventional therapy have been testified and continuous emergence of related domestic devices has greatly advanced development of the course on stroke prevention. As a domestic LAA closure occluder, MemoLefort shows good performance in clinical application and can safely and effectively guard against Cardiogenic stroke.

Professor Wang Hongtao presented Sharing of Operational Skills of MemoLefort LAA Closure Occluder I, and applied three cases of MemoLefort's clinical application experience and his personal experience in LAA closure to elaborate features and operational skills of MemoLefort, a domestic occluder with a plug design.

The First Affiliated Hospital of Xi’an Jiaotong University is one of the domestic clinical centers with ample experience in prevention and treatment of cardiogenic stroke. Professor Zhang Songlin used his experience on single-center ASD/PFO integrated LAAC closure “one-stop” operation to deliver a wonderful lecture on Treatment Strategies of Heart Disease Integrated Atrial Fibrillation and MemoLefort Clinical Application Experience.

At the conference, Professor Song Zhiyuan and Professor Zeng Anning also gave wonderful comments on use of MemoLefort LAA Closure Occluder I and the 'heart & Brain Cerebral Treatment’.

Professor Hu Hao, Professor Jiang Xiaofei, and Professor Zhang Yan, all surgeons who have practice with MemoLefort LAA Closure Occluder I, referred to their own ample clinical experience, and elaborated operating characteristics of MemoLefort occluder in the process of clinical use, and key points of operation and its characteristics and advantages as a domestic occluder with a plug design. Professor Hu Hao indicated that as a domestic occluder with a plug design, MemoLefort bore semblence other occluders with a plug design in key steps such as interatrial septal puncture, instrument preparation and exhaust, and sheath operation, so learning curve would be short, but it called for attention paid on particularities in depth and related operational aspects. Professor Jiang Xiaofei indicated that MemoLefort LAA Occluder had a moderate degree of hardness and could fit to different atrial appendage shapes well. Professor Zhang Yan indicated that MemoLefort was reasonable in designing and handy in operation, and showed good performance in clinical applications.

This surgical demonstration is a special case on ASD+PFO+LAA occlusion, in which the patient’s ASD is located in the lower position, but the defect is small, and it is difficult to apply ASD traffic to conduct LAA closure and axial direction is poor after it reaches the auricular appendage radiography through PFO. So Professor Zhang Yushun’s team applied the strategy of low-order puncture at the rear end close to ASD position, so that sheath can reach the upper atrial appendage and achieve better coaxiality. After comprehensive evaluation of DSA measurement and TEE measurement, Professor Zhang Yushun’s team applied a MemoLefort occluder with a disk diameter of 30mm for closure. After the occluder was unfolded, the occluder was stretched stably, was free from residual shunt or shoulders, and compression ratio was approximately 23%, perfectly in align with the principle of release.
