Complex Mitral Paravalvular Leak Closure

Transapical concomitant transseptal transcatheter closure of a giant mitral paravalvular leak under three‐dimensional printing guidance

“…In cases involving complex PVL anatomical structures, the accuracy of traditional assessment methods is often insufficient, and there may be a tendency to underestimate or overestimate the severity of the condition. [2][3][4][5] To address these limitations, preoperative in vitro evaluation and simulation utilizing 3D printing technology can serve as an effective remedy. 4,5 This approach offers a valuable solution to overcome the deficiencies in assessing complex PVLs, providing a more comprehensive and accurate understanding of the pathology.…”

Based on the results of the preoperative evaluation utilizing patient-specific 3D printed models, Joan et al 4 achieved successful transcatheter closure using two differently sized devices for patients with refractory heart failure and severe mitral PVL via the transapical approach.…”

Based on the results of the preoperative evaluation utilizing patient-specific 3D printed models, Joan et al 4 achieved successful transcatheter closure using two differently sized devices for patients with refractory heart failure and severe mitral PVL via the transapical approach. This method facilitated the accurate deployment of the devices onto the defect, ensuring optimal positioning and eliminating any potential disk interaction.…”

“…In recent years, the utilization of cardiovascular threedimensional (3D) printing technology has proven to be valuable in facilitating precise preprocedural assessment and guidance for certain structural interventions. 4,5 We present a case report on the transcatheter closure of a giant mitral PVL simultaneously via transapical and transseptal approaches. To evaluate the feasibility of the proposed plan and simulate the main procedures, we created a patient-specific 3D printed model.…”
