Change in Right-to-Left Shunt Fraction in Patients with Chronic Thromboembolic Pulmonary Hypertension after Pulmonary Endarterectomy

Oct 25, 2023 | mdpi.com | Lena Reimann |Laura Mayer |Simon Schneider |Esther I. Schwarz

4. DiscussionIn this retrospective study, we investigated the right-to-left shunt fraction (Qs/Qt) in patients with CTEPH whilst breathing pure oxygen (FiO2 1.0) during RHC at baseline and one year after PEA. Among all patients, the median shunt fraction was unchanged 1 year after PEA, but 7/16 (44%) patients improved their shunt fraction (>10% from baseline).
Domiciliary transcutaneous electrical stimulation in patients with obstructive sleep apnoea and limited adherence to continuous positive airway pressure therapy: a single-centre, open-label, randomised, controlled phase III trial

Aug 3, 2023 | thelancet.com | Michael Cheng |Esther I. Schwarz |Michael I. Polkey

SummaryHypoglossal nerve stimulation (HNS) for obstructive sleep apnoea (OSA) is a novel way to manage the condition. We hypothesised that in patients with OSA and limited adherence to continuous positive airway pressure (CPAP) therapy, domiciliary transcutaneous electrical stimulation (TESLA) would control sleep apnoea and provide health benefits.
