إجراء Cox-Maze IV المصاحب لجراحة الصمامات في Situs Inversus Dextrocardia: تجربة مركز واحد في الصين

Overview

This article summarizes the Cox-Maze IV procedure performed alongside valvular surgery in patients with situs inversus dextrocardia. The efficacy and safety of this approach are evaluated based on three patient cases.

Key Study Components

Area of Science

• Cardiac surgery
• Atrial fibrillation treatment
• Congenital heart defects

Background

• The Cox-Maze IV procedure is a surgical technique used to treat atrial fibrillation.
• Dextrocardia is a rare congenital condition where the heart is oriented to the right side of the chest.
• Valvular surgery may be necessary in patients with concurrent heart conditions.
• Understanding the safety and efficacy of surgical interventions in dextrocardia is crucial for improving patient outcomes.

Purpose of Study

• To evaluate the safety and effectiveness of the Cox-Maze IV procedure in patients with dextrocardia.
• To assess the role of 3D-printed heart models in preoperative planning.
• To document the surgical approach and outcomes in patients undergoing this combined procedure.

Methods Used

• Three patients with dextrocardia underwent the Cox-Maze IV procedure during valvular surgery.
• A median sternotomy was performed, and cardiopulmonary bypass was established.
• Cold-blood cardioplegia was administered for cardioplegic arrest.
• 3D-printed heart models were utilized for preoperative simulation and planning.

Main Results

• The Cox-Maze IV procedure was found to be safe and effective in eliminating atrial fibrillation in the studied patients.
• 3D-printed models facilitated better surgical planning and execution.
• All patients successfully underwent the combined surgical intervention.

Conclusions

• The Cox-Maze IV procedure can be safely performed in patients with dextrocardia.
• Utilizing 3D-printed models enhances surgical preparation and outcomes.
• Further studies are needed to establish long-term efficacy and safety.
