Research Paper on Surgical Repair Technique for Ventricular Septal Rupture Published in Annals of Thoracic Surgery Short Reports

Overview

Medical Education Inc. (Headquarters: Suginami-ku, Tokyo; Representative Director: Takashi Ochiai) announced that the research paper "Salvage Third-Patch Repair for Left Ventricular Free Wall Rupture After Double-Patch Septal Reconstruction," authored by Dr. Shin Yajima and colleagues at the Department of Cardiovascular Surgery, Osaka University, has been published in the academic journal "Annals of Thoracic Surgery Short Reports." This paper reports on a case where a left ventricular free wall rupture occurred following a double-patch repair of a ventricular septal perforation and ventricular septal dissection after a myocardial infarction, which was subsequently repaired using an additional patch via a left ventricular approach. The figures included in this paper were created by MEDICAL FIG., a service operated by Medical Education Inc.

Figures Used in This Study

These schematics illustrate step-by-step the left ventricular free wall rupture that occurred after the double-patch repair via the right ventricular approach, and the subsequent third-patch repair technique via the left ventricular approach, visually organizing the relationship between the progression of the surgery and the repair process.

Role of Figures in This Study

These figures serve to visually organize the structure of the leakage occurring after the double-patch repair via the right ventricular approach and the positioning of the third-patch addition. The cross-sectional views show the relationships between the left ventricle, right ventricle, septum, patch, and leakage pathway, enabling an understanding of the overall surgical structure. Furthermore, for the scene where the third patch is applied, the perspective is switched to a surgical field view, allowing for direct confirmation of the endocardial defect from the left ventricular side and illustrating exactly what the third patch covers. By combining cross-sectional views and surgical field views, the figure demonstrates the relationship between the overall structure and the local coverage operation performed by the third patch.

Key Points Considered in Figure Creation

During creation, emphasis was placed on the appropriate use of cross-sectional views and surgical field views. In the cross-sectional views, the structure was organized and expressed so that the positional relationships between the left ventricle, right ventricle, septum, existing patch, and leakage pathway could be understood. On the other hand, for the third patch scene, since the coverage area is difficult to convey in a flat way through cross-sections, it was expressed using a surgical field view from the left ventricular side. Peripheral information was kept to a minimum so that the relationship between the endocardial defect and the third patch could be the main focus.
