Abstract
We present our experience with the Cera (CO) and the CeraFlex occluder (CFO) in transcatheter closure of interatrial communications (IAC). Between 2013 and 2016, 201 patients (75 males, 16 with patent foramen ovale), aged 27 ± 19 (5–75) years, underwent percutaneous closure of IAC using CO or CFO in our institution. After transoesophageal imaging, the procedure was aborted in 7 young paediatric (6–13 years old) patients (3 multiple holes, 3 too small septum, 1 leak with 38 mm occlusion balloon). The occluder was removed prior to release in 11 patients (5.7%), while occlusion was successful in 183 patients (94.3%) with 44 CO, 136 CFO, and 3 Cera multifenestrated occluders. There were no deaths, embolizations, or major complications. Small residual shunts were demonstrated in 8 patients immediately after implantation, 4 (8.5%) with CO and 4 (2.9%) with CFO, all disappearing after 3 months. Over 1.8 ± 1.7 year follow-up, all patients improved with 2 asymptomatic, transient pericardial effusions and 5 adults with transient supraventricular arrhythmias, treated medically for 6 months. IAC closure with CO and CFO proved safe with favourable success rates and few, nonserious complications. The CFO flexible rotation feature helped in conforming to various septal anatomies, minimising manoeuvres and possibly post-occlusion leaks.
