Relationship between right-to-left shunt, hypoxia, and epilepsy.

ABSTRACT:

Objective

A right-to-left shunt (RLS) can mediate the hypoxic state, and hypoxemia is relevant for the development of drug-resistant epilepsy (DRE). The objective of this study was to identify the relationship between RLS and DRE and further investigate the contribution of RLS to the oxygenation state in patients with epilepsy (PWEs).

Methods

We performed a prospective observational clinical study of PWEs who underwent contrast medium transthoracic echocardiography (cTTE) between January 2018 and December 2021 at West China Hospital. The collected data included demographics, clinical features of epilepsy, antiseizure medications (ASMs), RLS identified by cTTE, electroencephalography (EEG), and magnetic resonance imaging (MRI). Arterial blood gas was also assessed in PWEs wit
