“…To our knowledge, the study herein is one of the first to adopt the CMP-IV procedure in a patient with situs inversus dextrocardia, which was successfully guided using rapid-prototyping techniques for the preparation of individualized lesion sets (18). In addition, the 3D printing model helps surgeons mimic and modify the CMP-IV procedure in patients with unfamiliar cardiac anatomy, particularly with rare malformations, supporting pre-operative planning and training (19) in surgical ablation for AF.…”

The safety and efficacy of the Cox-Maze IV procedure (CMP-IV) for situs inversus dextrocardia patients with atrial fibrillation is yet to be determined. Herein, we present the case of a 39-year-old male patient admitted to our cardiac center following progressive exertional dyspnea. The patient was diagnosed with situs inversus dextrocardia, severe mitral regurgitation, and paroxysmal atrial fibrillation. A three-dimensional (3D) heart model printing device embedded with designated ablation lines was used for pre-operative planning. Mitral valvuloplasty, CMP-IV, and tricuspid annuloplasty were performed. The patient had an uneventful recovery and was in sinus rhythm during a 12-month follow-up period using a 24-h Holter monitoring device. The case herein is one of the first to report on adopting the CMP-IV procedure for situs inversus dextrocardia patients with complex valvuloplasty operation. In addition, the 3D printing technique enabled us to practice the Cox-maze IV procedure, given the patient's unique cardiac anatomy.
