Evidence of Atrial Functional Mitral Regurgitation Due to Atrial Fibrillation

Abstract: AF can result in "atrial functional MR" that improves if sinus rhythm is restored.

“…Considering extreme LA dilatation is the primary cause of atrial MR, therapeutic strategies to prevent or reverse the LA remodeling caused by AF should be emphasized, as previously reported. 4 Further, PML tethering independently aggravated the atrial functional MR, along with the annulus area, and therefore, a therapeutic approach for both the annulus and leaflets, such as simultaneous annuloplasty and chordal reconstruction, may be important options for correction of atrial functional MR.…”

“…Wady zastawkowe mogą się wiązać ze zwiększonym ryzykiem zakrzepowo-zatorowym, które prawdopodobnie sumuje się z ryzykiem udaru mózgu u pacjentów z AF [263]. Podobnie jak w przypadku niewydolności serca, wady zastawkowe i AF wchodzą we wzajemne interakcje i podtrzymują się wzajemnie poprzez przeciążenie objętościowe i ciśnieniowe, kardiomiopatię tachyarytmiczną, a także za pośrednictwem czynników neurohumoralnych [264][265][266][267][268][269][270]. Jeżeli dysfunkcja zastawki jest ciężka, to AF moż-na uważać za wskaźnik postępującej choroby, a więc jego obecność przemawia za naprawą lub wymianą zastawki [271].…”

“…Mitral regurgitation (MR) severity was also assessed by color Doppler flow mapping of spatial distribution of the regurgitant jet within the left atrium in both apical 4‐chamber and apical 2‐chamber views, and the ratio of the maximal regurgitant area to left atrium area was obtained. Significant MR was defined as moderate or severe MR (≥20% of the ratio of the maximal regurgitant area to left atrium area) 23, 24…”
