摘　　要：BACKGROUND Dextroversion is defined as the presence of dextrocardia with situs solitus,dextroloop ventricles,and normally related great arteries.Dextrocardia can pose technical challenges when interventional treatments are required.However,the challenges posed by dextroversion can be amplified due to the disruption of typical anatomical relationships,the unpredictable positioning and boundaries of cardiac structures resulting from the shift,and the pathological processes influencing rotation.CASE SUMMARY A 73-year-old woman with cardiac dextroversion suffered from a recurrence of atrial fibrillation after her radiofrequency catheter ablation and Despite the cessation of antiarrhythmic medications,there were episodes of sinus pauses and symptomatic bradycardia,with heart rates dropping as low as 28 beats per minute.CONCLUSION Dextroversion makes the implantation of leadless pacemakers more challenging,and appropriate adjustments in fluoroscope angles may be crucial for intracardiac operations.Additionally,when advancing delivery systems,attention should be paid to rotational direction during valve-crossing procedures;changes in the perspective of posture angle between normal cardiac position and dextroversion can serve as references.
