Early Hemodynamic Changes and Long-Term Outcome Of Patients With Severe Low Gradient Aortic Stenosis After Transcatheter Aortic Valve Replacement.

CONCLUSIONS: NFLG-AS was the most prevalent form of LG severe AS and was associated with adequate left ventricular compensation and good prognosis. On the other hand, CLFLG-AS represents the heart-failure with reduced ejection fraction (HFrEF) form of AS and was associated with the worst prognosis, whereas PLFLG-AS represents the heart-failure with preserved ejection fraction (HFpEF) form of AS with intermediary prognosis. Both groups showed early hemodynamic reverse response after TAVR. PMID: 31566569 [PubMed - as supplied by publisher]
