IS DOPPLER TISSUE EARLY LEFT VENTRICULAR FILLING VELOCITY PRELOAD INDEPENDENT OF PRELOAD ALTERING MANEUVERS?

Abstract

Objective. Transmitral Doppler flow indices are used to evaluate diastolic /uncfion. Recently, Dofiipler tissue velocities have been used as an index of lefi ventricular relaxation. The aim of this study was to determine whether Doppler tissue velocities are influenced by |ore- load alterations. Methods. We altered lefi ventricular |oreIoads in I7 patients (all men, 49z8 years) while recording echocar- diogra|ohic measurements of left ventricular end-diastolic volume, leff atrial maxima/ area, |oeak early Doppler fill- ing velocity and lefi ventricular myocardial velocities during early filling. Preload altering maneuvers included Trendelenburg (Stage 1), reverse Trendelenburg (Stage 2) and amyl nitrate (Stage 3). Systolic blood pressures were taken at every stage. Results. Compared to baseline left ventricular end diastolic volume (p——0,001), left atrial area ( p-—0,003), fi›eak early mitral Doppler filling velocity ( fi›——0,01) and systolic blood pressures (|o——0,001) were changed as a result of preload a/tering maneuvers. Only left ventricu- lar myocardial velocities during early filling were signif- icantly unaffected by f›reload altering maneuvers. Conclusion. In contrast to standard transmitral Doppler filling indices, Doppler tissue early diastolic ve/ocities are not significant/y affected by physiological preload altering maneuvers. Thus, Doppler tissue veloc- ities during early left ventricular diastole may be more useful as an index of diasto/ic function by fi›roviding a fiireIoad-inde[:iendent assessment of left ventricular fill- ing.

DOPPLER DOKUSU ERKEN SOL VENTRİKÜL DOLUM HIZI ÖN YÜKLEME, ÖN YÜKLEMEYİ DEĞİŞTİREN MANEVRALARDAN BAĞIMSIZ MIDIR?

Abstract

Amaç: Transmitral Doppler akım verileri diyastolik fonksiyonu değerlendirmek için kullanılmıştır. Son za- manlarda, Doppler doku kızları sol ventrik’ül gevşemesi- nin bir göstergesi gi/7i kullanılmıştır. Bu çalışmada Dopp- ler doku hızlarının ön y”ük degiştirici manevralardan et- kilenifiı etkilenmediğinin saPtanması amaçlandı. Yöntem: 17 hastada (t”ümü erkek, 49 x 8) ekokardiyog- raFık sol ventrik”ûl miyokardiyum hızları ölü”ümlerini ya- parken sol ventrik’ül ön y”dk”ünü değiştirdik Trendelen- burg (l. basamak), ıers Trendelenburg (2. basamak) and amil nitrat (3. basamak) ön y’ilk deyiştirici manevralar olarak kullanıldı. Her basamak için sistolik kan basıncı ölç‘üld”ü. Sonuçları Baş/ang/ç ile karşılaştırılınca, soJ ventrikıfil diyastol hacmi (p-—0,001), sol atriyum alanı ([:›——0,003), [:›ik erken mitra/ Doppler dolum hızı (p—-0,001) ve sisto- Iik kan basınçları (p——0,001) ön yük değiştirici manevra- lar ile değişti, ancak sol ventrik”ül miyokardı hızı erken dolumda ön y”ük defi,iştirici manevralar ile anlamlı değiş- medi. Yorum• Mitral seviyeden Do[:ıpler dolum verilerinin tersine, Dopfi›ler doku erken diyastol hızları fizyolojik ön y'ük değişfirici manevralardan önemli derecede etkilen- mez. Böylece erken sol ventrik’ül diyastolu sırasında Doppler doku hız/arı sol ventrikü/ diyastolu sırasında DoPpler doku hızları sol ventrik”dl dolumunun ön y'ük- den bağımsız değerlendirilmesini sağlayan daha yararlı bir g”dsterge olabilir.
