Romatizmal mitral kap ak alanı valsalva manevrası ile değişir

Amaç. Mitral darlığı, halen dünyanın bir problemidir. Ekokardiyografi, mitral darlığınındeğerlendirilmesinde, altın standart olarak kabul edilmektedir. Biz, valsalva manevrasının en eskiyöntem olan planimetrik kapak alanı ölçümüne etkisini araştırmayı amaçladık. Yöntem. Mitraldarlığı olan 60 ardışık hasta çalışmaya dahil edildi. Hastalara valsalva yaptırıldı ve ölçümleryapıldı. Bulgular. Ortalama kapak alanı başlangıçta planimetrik olarak 1,5±0,4cm2idi ve 1,3-2,1cm2arasında değişiyordu. Tüm grupta, valsalva manevrası planimetrik kapak alanında birdeğişikliğe yol açmadı, ancak, diğer ölçümler, gradientler, sistolik pulmoner arter basıncı,velositeler azaldı. Sonuç. Mitral darlığı hastalarında valsalva manevrası ekokardiyografikölçümleri değiştirir, ancak planimetrik kapak alanı değişmez.

Rheumatic mitral valve area changes with valsalva maneuver

Aim. Mitral stenosis, is still a problem of the world. Echocardiography is accepted as goldstandard for the evaluation of mitral stenosis. We aimed to search influence of valsalva maneuveronto measurement of mitral valve area (MVA) by planimetry, oldest method. Methods. Sixtyconsecutive patients with mitral stenosis were enrolled. Valsalva maneuver was performed bypatients and measurements were done. Results. Mean MVA at baseline was 1.5±0.4cm2byplanimetry, ranging between 1.3-2.1 cm2. In the overall group, Valsalva maneuver did not yieldany change in MVA by planimetry. Considering other measurements, gradients, SPAP, velocitiesdecreased up on Valsalva maneuver. Conclusion. Valsalva maneuver influencesechocardiographic measures in patients with mitral stenosis, but not, planimetric valve area
