AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with atrial fibrillation who are having catheter ablation together with left atrial appendage closure in one procedure. It measures pressure in the heart's upper chambers before and after.

- Original description
One-stop procedure combining catheter ablation (CA) and left atrial appendage closure (LAAC) has been a feasible treatment for patients with atrial fibrillation at high risk of stroke and/or bleeding. Although it could achieve considerable rhythm control and stroke prophylaxis, a number of patients has experienced progressive heart failure after the procedure. Notably, previous studies indicate that both pulmonary vein isolation by CA and LAAC could significantly increase left atrial pressure, while currently no study has investigated left atrial pressure change in patients underwent combined procedure. The investigators hypothesise that combined procedure would significantly increase left atrial pressure and subsequently deteriorate cardiac function. Therefore, the investigators aim to measure the left and right atrial pressure change before and after CA and LAAC in combined procedure, and investigate the influence of the pressure change on clinical outcomes.Read full original descriptionShow less
The Impact of Atrial Pressure Change Before and After One-stop Procedure Combining Catheter Ablation and Left Atrial Appendage Closure on the Prognosis of Patients With Atrial Fibrillation
One-stop procedure combining catheter ablation (CA) and left atrial appendage closure (LAAC) has been a feasible treatment for patients with atrial fibrillation at high risk of stroke and/or bleeding.

Notably, previous studies indicate that both pulmonary vein isolation by CA and LAAC could significantly increase left atrial pressure, while currently no study has investigated left atrial pressure change in patients underwent combined procedure. The investigators hypothesise that combined procedure would significantly increase left atrial pressure and subsequently deteriorate cardiac function. Therefore, the investigators aim to measure the left and right atrial pressure change before and after CA and LAAC in combined procedure, and investigate the influence of the pressure change on clinical outcomes.
