TL;DR
DCCV during LAAO appears technically feasible in selected patients, although larger studies are needed to confirm safety, and no device migration, embolization, significant peridevice leak, or neurologic events occurred.
Abstract
Purpose
We report the first cases of direct current cardioversion (DCCV) performed during percutaneous left atrial appendage occlusion (LAAO) in patients with left atrial appendage thrombus and assess its technical feasibility.
Methods
Three patients with left atrial appendage thrombus and absolute indications for LAAO underwent DCCV during the procedure because of hemodynamic instability from rapid atrial fibrillation.
Results
A single 200-J shock restored sinus rhythm in all patients. No device migration, embolization, significant peridevice leak, or neurologic events occurred. Follow-up imaging confirmed stable device position.
Conclusions
DCCV during LAAO appears technically feasible in selected patients, although larger studies are needed to confirm safety.
BACKGROUND
Acute postcardioversion left atrial appendage (LAA) low-flow states are recognized but likely underdetected, as repeat appendage imaging is not routine after sinus restoration.
CASE SUMMARY
Three patients undergoing left atrial appendage closure (LAAC) developed new LAA spontaneous echo contrast, dense spo...

Background Left atrial appendage closure (LAAC) is increasingly used for stroke prevention in atrial fibrillation, but rare structural complications may occur and require percutaneous treatment. Case Summary A 76-year-old man with atrial fibrillation/flutter was referred for LAAC after LAA thrombus was found on transes...

The findings support the safety of LAAC with respect to cardiac functional recovery and demonstrate that the procedure does not adversely affect cardiac performance in patients with AF receiving guideline-directed medical therapy.

Left atrial appendage occlusion is a non-pharmacological method for preventing thromboembolic complications in patients with atrial fibrillation. Due to the high prevalence of atrial fibrillation worldwide and in the Russian Federation, the number of patients requiring prevention of its thromboembolic complications w...

Left atrial appendage closure (LAAC) has emerged as an important alternative strategy for stroke prevention in patients with non-valvular atrial fibrillation (NVAF), particularly when long-term oral anticoagulation (OAC) is contraindicated or poorly tolerated. Initially developed as a surgical technique based on ligati...
