Interatrial shunt devices for the treatment of heart failure.

Despite ongoing advances in the treatment of heart failure, overall symptom burden remains high. Underlying the primary symptom of dyspnea are often elevations in left atrial pressures, which occur across the spectrum of heart failure subgroups. Current therapies do not directly address improvements in left atrial pressures; however, passive left atrial decompression may offer a new avenue to treat heart failure. New technologies are currently being evaluated in clinical testing and may offer a novel therapeutic approach to heart failure.
