[Paper Published] Research Results on Papillary Muscle Relocation for Mitral Regurgitation with Left Ventricular Aneurysm Published in JTCVS Techniques

Overview Medical Education Co., Ltd. (Headquarters: Suginami-ku, Tokyo; Representative Director: Takashi Ochiai) announces that the research paper "Papillary muscle relocation for mitral regurgitation attributable to flail but tethered commissure associated with a left ventricular aneurysm" by Dr. Hiromitsu Teratani et al. from the Department of Cardiovascular Surgery, Fukuoka University Hospital, has been published in the academic journal 'JTCVS Techniques'.

This paper is a case report of repair including papillary muscle relocation for mitral regurgitation presenting with papillary muscle displacement associated with a left ventricular aneurysm, accompanied by flail but tethered commissure. It describes the management of complex lesions involving chordal rupture and leaflet tethering.

MEDICAL FIG., operated by Medical Education Co., Ltd., was responsible for the production of the figures included in this paper.

Figures Used in This Study

A figure that visually organizes the preoperative condition due to papillary muscle displacement and chordal rupture associated with a left ventricular aneurysm, and sequentially presents the techniques of papillary muscle separation, approximation suture of papillary muscle heads, and edge-to-edge suture. The configuration allows for a visual grasp of the relationship between the pathology and the surgical techniques.

Role of the Figure in This Study

This figure was created as a "schematic diagram visually demonstrating the pathology and surgical techniques" requested during the peer-review process. The diagram organizes the location of the left ventricular aneurysm, the boundary with normal myocardium, and the relationship between ventricular deformation and papillary muscle displacement caused by the aneurysm, allowing for an understanding of the preoperative pathological concept. Additionally, it sequentially arranges the procedural steps of papillary muscle separation, approximation suture of papillary muscle heads, and leaflet fixation. This configuration enables readers to grasp not only the key points of the surgical procedure but also the relationship between the underlying pathology and the surgical maneuvers within a single figure.

Points Considered in Figure Production

In producing the figure, the pathology was organized to clearly convey the relationship between the ventricular morphological changes due to the left ventricular aneurysm and the accompanying papillary muscle displacement. Specifically, in addition to the positional relationship of the papillary muscle heads, the location of the left ventricular aneurysm and its boundary with normal myocardium were shown, and the color tones of the aneurysmal and normal walls were differentiated to create a visually understandable representation.

Furthermore, in the procedural diagrams, the steps of papillary muscle separation, approximation suture of papillary muscle heads, and leaflet fixation were arranged sequentially, facilitating a natural understanding of the relationship between the pathology and surgical maneuvers, thereby helping readers grasp the overall picture.
