Introduction: To date, totally 3D-endoscopy has primarily been employed in mitral, tricuspid, and aortic valve surgeries. Herein, we describe the first case of a pulmonary valve surgery using totally 3D-endoscopy. To the best of our knowledge, this is the first case of a totally endoscopic pulmonary valve surgery. Case report: A 56-year-old woman was provisionally diagnosed with a tumor arising from the left cusp of the pulmonary valve. Totally 3D-endoscopy was planned for tumor resection. The patient was placed in a modified right lateral decubitus position and underwent mild hypothermic cardiopulmonary bypass using the left femoral artery, right jugular vein, and right femoral vein. An on-pump beating-heart technique was used during this surgery. Trocars for the 3D-endoscopic system and surgical instruments were inserted through the third and fourth intercostal spaces. Upon incision of the pulmonary artery, the suspected tumor was revealed to be a hyperplastic left pulmonary cusp; therefore surgical resection was abandoned. The patient was discharged without any complications. Conclusion: This case demonstrates that a totally 3D-endoscopic approach may provide optimal views of the pulmonary valve. Moreover, this procedure would be a novelty in MICS.
