Abstract

Aim: In cases with pulmonary hypertension, because of the advantages, routine pulmonary hypertension can be measured by using noninvasive/echocardiographic tricuspid insuffiency. But, as in patients without tricuspid insuffiency it&#8217;s not possible to use this method, other echocardiographic parameters have being searched. In this study, we tried to emphasize the importance of these values. Material and Method: In 74 patients included in the study, the relation between pulmonary strain, pulmonary peak acceleration time, pulmonary ejection time, acceleration time index and other Doppler parameters have been searched. Results: With estimated pulmonary artery pressure, pulmonary strain (r=-0.670 p<0.0001), pulmonary acceleration time/peak period of flow rate(r =-0.665 p<0.0001), pulmonary ejection time(r =-0.346 p<0.003), acceleration time index (r=-0.447 p<0.0001) and RVEd/right ventricular tissue Doppler early diastolic flow rate (r=-0.404 p<0.0001) are found to be related. Conclusion: In cases in whom tricuspid insuffiency can&#8217;t be recorded, noninvasive and echocardiographic pulmonary artery strain can be used to estimate pulmonary artery pressure.

Özet

Amaç: Pulmoner hipertansif olgularda rutin pulmoner arter basıncı, avantajları nedeni ile noninvasiv/ekokardiyografik triküspid yetersizliği üzerinden ölçülebilmektedir. Ancak triküspid kapak yetersizliği olmayan hastalarda bu yöntemin kullanılması mümkün olmadığından ekokardiyografik başka parametrelerin arayışına geçilmiştir. Biz de çalışmamızda bu değerlerin önemini vurgulamaya çalıştık. Gereç ve Yöntem: Çalışmaya dahil edilen 74 hastada transtorasik ekokardiyografi ile pulmoner strain, pulmoner pik akselerasyon zamanı, pulmoner ejeksiyon süresi, akselerasyon zaman indeksi ve diğer Doppler parametreleri ile ilişkisi araştırıldı. Bulgular: TPAB (tahmini pulmoner arter basıncı) ile pulmoner strain (r= -0,670 p<0,0001), pulmoner akselerasyon zamanı/akım hızının pik süresi (r=-0,665 p<0,0001), pulmoner ejeksiyon süresi (r = - 0,346 p<0,003), akselerasyon zaman indeksi(r= -0,447 p<0,0001) ve SVEd/sağ ventrikül doku Doppler erken diyastolik akım hızı (r= -0,404 p<0,0001) ilişkili saptandı. Sonuç: Triküspid yetersizliğinin kaydedilemediği olgularda pulmoner arter basıncını belirlemede hasta başı noninvaziv ve ekokardiyografik olarak kolay ölçümü yapılabilecek olan pulmoner arter strain kullanılabilir.
