RESUMO
AIMS: To assess the usefulness of miniature transoesophageal echocardiography using a 10 F intracardiac probe (ICE-TEE) for transseptal catheterization during atrial fibrillation (AF) ablation. METHODS AND RESULTS: Intracardiac echocardiography probe was used transoesophageally in 79 consecutive patients (56 ± 11 years, 73% male) referred for AF ablation (60% paroxysmal and 38% persistent) to guide transseptal puncture. Transseptal catheterization monitored by ICE-TEE was well tolerated and successfully performed in all patients without any sedation. No mechanical oesophageal complication was noted. Moreover, the mean duration between ICE-TEE probe insertion and successful transseptal puncture was 4.5 min and the mean time of ICE-TEE was 10 min. Finally, no tamponade occurred during the AF ablation procedure. CONCLUSION: Intracardiac echocardiography-TEE is safe and well tolerated for the guidance of transseptal catheterization during AF ablation. Moreover, this technique was performed without requiring any anaesthesia.

AIMS: To evaluate the use of intracardiac echocardiography probe through oesophageal route (ICE-TEE) for the monitoring of percutaneous foramen ovale (PFO) closure procedure. METHODS AND RESULTS: The study was conducted in 50 patients divided into two groups: in group I (n = 24), accuracy of ICE-TEE in assessing the inter-atrial septum (IAS) was compared with standard TEE, and in group II, we used ICE-TEE to monitor 26 consecutive patients referred for PFO closure. In group I, IAS was constantly visualized with a close correlation between ICE-TEE and standard TEE for IAS excursion (r = 0.9, P < 0.0001). In group II, ICE-TEE allowed to rule out four patients (three without PFO and one with septal atrial defect associated) and identified three complications during PFO closure procedure (pericardial effusion, inadequate device deployment, and cardiac thrombus). Finally, device implantation was successfully performed in the 22 patients with no residual shunt and thrombus observed after 3 months. CONCLUSION: ICE-TEE could be used to monitor PFO closure procedure.
