Özet
Diyastolik posterior duvar straininin mitral yetmezliğini öngördürmedeki önemi. Posterior duvar straininin, mitral yetmezliğinin (MY) şiddeti ile aralarinda ilişki ve posterior duvar straininin mitral yetmezliğinin şiddetini öngördürmedeki değerini göstermek.Olguların yaş, cinsiyet, komorbidite, laboratuvar, kan basınçları ve pulmoner arter basınçları, EF'leri, sol atriyum (LA) ve sol ventrikül (LV) boyutları ve etkilenimleri, E ve A dalga paternleri,septum ve serbest duvar hareketine etki eden faktörlerin strain ile olan ilişkisi incelendi. Çalışmamızda hastaların yaş ortalaması 35,2±7,2 yıl olup, %47,5 erkekti. Kontrol grubunun strain ortalaması % 37,1±6,3 hafif-orta MY'li hastaların strain ortalaması %26,8±8,2 ve ciddi MY'li hastaların strain ortalaması %14,7±4,0 olarak tesbit edildi. Ciddi MY'li hastaların strain oranı, kontrol ve hafif-orta MY'li hastalardan; hafif-orta MY'li grubun strain oranı kontrol grubundn anlamlı olarak düşük saptandı (p<0,05). Yaş ile strain arasında negatif yönlü korelasyon saptandı (p<0,05). Cinsiyet ve strain arasında saptanmadı (p>0,05). Strain oranının hemoglobin ile pozitif, üre ile negatif yönlü korelasyon gösterdiği saptandı (p<0,05). Kreatinin düzeyi ve strain oranı arasında ilişki saptanmadı (p>0,05). Strain oranının pulmoner arter basıncı ile negatif yönlü, EF ile pozitif yönlü korelasyon verdiği saptandı (p<0,05). SKB ve DKB'nin strain ile korelasyon vermediği saptandı (p>0,05). Strain oranının LA hacmi, LV sistolik çapı, LV diyastolik çapı, pulmoner arter çapı ve A dalgası ile arasında negatif yönlü korelasyon verdiği (p<0,05); TAPSE, MAPSE, E dalgası E/A ortalaması ile korelasyon vermediği saptandı (p>0,05).Strain oranının septum IVRT'si, septum EM'si, serbest duvar SM'si, serbest duvar EM'si, serbest duvar AM'si, posterior duvar sistolü ile pozitif yönlü korelasyon verdiği (p<0,05);septum ET'si ve posterior duvar diastolü ile negatif korelasyon verdiği saptandı (p<0,05). MY için strain kesim değeri 0,31'de; %87,2 sensitivite ve %82,1 spesifite olarak ölçüldü. Sonuç olarak; MY derecesi ve strain arasında negatif bir ilişki olup, MY ciddiyeti artıkça kardiyak strain miktarında azalma görülür. Ölçülen strain değeri MY şiddetini öngörmede yüksek oranda etkili olarak bulunmuştur.
Preventing mitral regurgitation of diastolic posterior wall strain. To show the relation between the posterior wall strain and the severity of mitral regurgitation and the value of the posterior wall stroma to predict the severity of mitral regurgitation. Factors influencing septum and free wall motion are age, gender, comorbidity, laboratory, blood pressure and pulmonary pressures, EFs, left atrium (LA) and left ventricle (LV) dimensions and effects, E and A wave patterns, relationship has been studied. The mean age of the patients in our study was 35.2 ± 7.2 years and 47.5% were male. The strain average of the control group was 37.1 ± 6.3%, the strain average of patients with mild-to-moderate MR was 26.8 ± 8.2%, and the strain average of patients with severe MR was 14.7 ± 4.0%. The strain rate of patients with severe MR, control and mild-to-moderate MR; the strain rate of the mild-moderate group was significantly lower than the control group (p <0.05). There was a negative correlation between age and strain (p <0.05). There was no correlation between sex and strain (p> 0.05). Strain rate was positive with hemoglobin and negative correlation with urea (p <0.05). There was no correlation between creatinine level and strain rate (p> 0,05). Strain ratio was negatively correlated with pulmonary artery pressure and positively correlated with EF (p <0,05). It was determined that SBP and DBP did not correlate with strain (p> 0,05). Strain ratio was found to be negatively correlated with LA volume, LV systolic diameter, LV diastolic diameter, pulmonary artery diameter and A wave (p <0,05); strain ratio was not correlated with TAPSE, MAPSE, E wave mean E / A ratio (p >0,05). Strain ratio was positive correlated with septum IVRT, septum EM, free wall SM, free wall EM, free wall AM, posterior wall systole (p <0,05); strain ratio was found to be negatively correlated with septum ET and posterior wall diastole (p <0,05). Strain cut value for MY is 0.31; 87.2% sensitivity and 82.1% specificity. As a result; There is a negative correlation between MY grade and atrial strain and a decrease in the amount of residual cardiac strain in MY severity. The measured strain value was found to be effective in high range without predicting the intensity of MY.
