\begin{abstract}
\textbf{Background:}~Left atrial appendage occlusion (LAAO) in the
treatment of atrial fibrillation (AF) has become a hot topic in clinical
research in recent years. \textbf{Case presentation:~}we report a
68-year-old female patient who was admitted for ``recurrent palpitations
for three years,'' with an electrocardiogram finding of atrial
fibrillation (Figure {[}1{]}(\#fig-cap-0001)). The diagnosis upon
admission was: (1) arrhythmia: paroxysmal AF (CHA2DS2-VASc: 4 points,
HAS-BLED: 3 points), (2) Grade~3~hypertension, and (3) carotid plaque
with internal carotid artery stenosis. The patient had a history of AF
for three years with poor drug treatment effect. The patient was unable
to tolerate anticoagulation therapy. We gave the patient a one-stop
procedure treatment of ``AF radiofrequency ablation + LAAO'' under the
guidance of 3D printing technology. There was no recurrence of AF or
paravalvular leakage at the three-month and one-year follow-ups.
\textbf{Conclusions:} The 3D printing technology guide the one-stop
operation of ``AF radiofrequency ablation + LAAO'' is helpful. But it
whether can improve the prognosis and quality of life of patients,
further multi-center research and large data statistics are required.%
