Does left atrial-to-coronary sinus shunting adversely impact right ventricular function in patients with heart failure?
This early feasibility study follow-up investigates the long-term impact of left atrial-to-coronary sinus shunting on right ventricular function in heart failure patients.
Exertional dyspnea attributable to elevations in left atrial pressure (LAP) is a hallmark symptom of heart failure. As an adjunct to guideline-directed medical therapy, therapeutic shunting devices have been explored as a mechanism to unload the left atrium, decongest the lungs, and relieve symptoms. However, studies in longitudinal heart failure have demonstrated a propensity for progressive right ventricular (RV) dilation and dysfunction, particularly among patients with heart failure with preserved ejection fraction (HFpEF), and thus, there is a legitimate concern that interatrial shunts could adversely impact the right heart or accelerate this process.
