Abstract

The Chiari network is an embryonic remnant of the sinus venosus valve, which is characterized by a fenestrated, netlike structure in the right atrium and has the potential to be misdiagnosed as another right atrial pathology. Additionally, the Chiari network has been frequently reported to entrap intracardiac devices during surgical procedures. In this case report, we present two patients with a Chiari network confirmed by three-dimensional transesophageal echocardiography, which assisted in preventing device entrapment during intracardiac procedures.
