Key result
Left atrial shunting devices remain under investigation to alleviate HF symptoms pending optimal candidate selection.
Why the study?
Despite approved treatments, many patients with heart failure continue to have disabling symptoms from left atrial hypertension, leaving the optimal candidate for interatrial shunt devices an active area of research.
Left atrial shunting devices are an active area of research for alleviating left atrial hypertension and symptoms in patients with heart failure, particularly HFpEF.
Left atrial shunting warrants no practice change yet; leaves open optimal candidate selection in HF.
Left atrial (LA) hypertension is central in the pathophysiology of heart failure (HF) in general and of HF with preserved ejection fraction (HFpEF) in particular. Despite approved treatments, a number of HF patients continue experiencing disabling symptoms due to LA hypertension, causing pulmonary congestion, pulmonary hypertension, and right heart dysfunction, at rest and/or during exercise. LA decompression therapies, i.e., left atrial shunting through a specifically designed device (either implant-based or implant-free), are being studied in various forms of HF to alleviate LA hypertension and patients' symptoms. Despite a solid background and favorable signals from initial non-randomized clinical trials, the quest for the optimal HF candidate for interatrial shunt devices is still an area of active research that at the same time is helping to better elucidate the intricate pathophysiology of HF(pEF).

Lorenzo et al. (2025) conducted a review in Heart failure (HF) and HF with preserved ejection fraction (HFpEF). Left atrial shunting devices was evaluated. Left atrial shunting devices are under active investigation to alleviate left atrial hypertension and symptoms in heart failure, with the optimal patient candidate still being determined.
