Mitral Valve Prolapse (MVP1 syndrome is one of the most prevalent
cardiac valvular abnormalities. In this study we investigated the predic
tors ofatrialfibrillation (AF)prevalence inpatientswithMVP.
Eighty three' adult patients with echocardiographic diagnosis ofMVP
were subjected to thefollowing :-.
-Full history taking and thorough clinical examination.
-Electrocardiography on two occasions in. at least six weeks apart to
selectpatientswithchronicAF.
-Mmode, 2-dimensioncd colorDoppler transthoracic echocardiography
weredoneforallpatients.
Sixty two patients had sinus rhythm and twenty one patients had
. chronicAF. Therewas no difference in sex hypertension, diabetes meilitus,
smoking and hypercholesterolemia between sinus rhythm and AF
groups. Except for age, patients with AF were significantly older than
thosewithsinus rhythm.
The left atrial diameter and left ventricular end-diastolic dimension in
theAFgroup were greater than those in sinus rhythmgroup. Mitral regurgitation
(MR) in the AFgroup was more sever than in the sinus rhythm
group. Therewas nodifference infractionalshortening betweenthe sinus
rhythmandAF_ group. In conclusion, the degree ofMR, the site ofMVP
and left atril diameter were independent predictors ofAFprevalence in
patientswithMVP. |
