Long-term follow-up of IASD implantation in a patient with HFpEF showed prevention of HF hospitalization but highlighted the need for increased diuretic therapy to manage left-to-right shunt-induced volume overload.
Should not yet change practice in severe HFpEF; leaves open whether interatrial shunts prevent hospitalization.
We herein present a case study of a patient with heart failure with a preserved ejection fraction and severe symptoms who underwent interatrial shunt device implantation and follow-up at a tertiary care heart failure clinic. The interatrial shunt device implantation was successful. No adverse events occurred, and the device prevented hospitalization for heart failure during long-term follow-up.
No takes yet. Share an insight, caveat, or question.
