Abstract
Relation of right-to-left shunt (RLS) with chronic hyperventilation syndrome (CHVS) has not been previously reported. We evaluated the prevalence of RLS in patients with CHVS. Patients with CHVS and 25 healthy controls (CG) were recruited into the study. Vascular RLS was diagnosed using contrast TCD. Of 25 subjects with CHVS, 16 (64%) had RLS vs 3 from CG (12%). TEE confirmed PFO in 10 patients with CHVS (40%) vs 2 from CG (8%). Pulmonary AVM was found in chest CT in 2 patients (10%) with CHVS and none from CG. The prevalence of RLS and PFO in patients with CHVS was significantly higher than in healthy subjects.
