“…Utvrđeno je da je frakciono skraćenje izlaznog trakta desne komore u boljoj korelaciji sa sistolnim pritiskom plućne arterije u poređenju sa dvodimenzionalnim M-mod mjerenjem sistolne longitudinalne funkcije slobodnog zida desne komore [18]. Objavljeno je više studija koje su poredile vrijednosti brzina pulsnog tkivnog doplera trikuspidnog anulusa sa podacima dobijenim radionuklidnom angografijom, a koje su pokazale dobru korelaciju i dobru sposobnost razlikovanja normalne i patološke sistolne funkcije, odnosno, ejekcione frakcije desne komore.…”

Uvod. Poremećaji funkcije desnog srca su prediktori loše prognoze kod pacijenata na programu hronične hemodijalize (HD). U ovoj studiji ispitivana je validnost ehokardiografije u procjeni sistolne i dijastolne funkcije desne komore kod pacijenata na HD.Metode. Istraživanjem je obuhvaćeno 30 pacijenata (55±11 godina) na hroničnoj HD kojima su rađene standardna 2D ehokardiografija i tkivni Doppler, prije i nakon HD.Rezultati. Ispitivanje sistolne funkcije desne komore prije i poslije HD je pokazalo da su frakciona promjena površine -FAC (36%±11 vs. 34%±11, p=0,464) i amplituda sistolne pokretljivosti anulusa trikuspidne valuvle -TAPSE (25,2mm±4,8 vs. 24,2mm±5, p=0,207) bile u granicama normalnih vrijednosti, nezavisno od smanjenja ukupnog volumena krvi nakon HD, dok je frakciono skraćenje -Fs (43,8%±11,6 vs. 39,3%±13,2, p=0,014) bilo značajno manje nakon HD, što pokazuje zavisnost ovog parametra od smanjenja cirkulatornog volumena. Tei indeks desne komore pokazao je normalne vrijednosti, nezavisno od smanjenja punjenja desne komore nakon HD (0,59±0,44 vs. 0,69±0,27, p=0,18). Evaluacija dijastolne funkcije desne komore preko brzina transtrikuspidnog protoka (E talas, E/A) pokazala je značajno smanjenje brzina nakon smanjenja volumena poslije HD, dok je odnos brzina E/E' (6,02±3,19 vs. 5,66±1,83, p=0,599) ostao u granicama normalnih vrijednosti i nakon HD.Zaključak. Ehokardiografska procjena sistolne funkcije desne komore pomoću FAC i TAPSE, kao i procjena globalne funkcije miokarda pomoću Tei indeksa, su pouzdane metode kod pacijenata na HD, pošto se njihove vrijednosti nisu mijenjale u uslovima smanjenja cirkulatornog volumena nakon HD. Kao pouzdan parametar za procjenu dijastolne funkcije kod pacijenata na HD se može koristiti odnos brzina E/E', koji se u ovom istraživanju nije značajno mijenjao usljed smanjenja volumena krvi nakon HD.Ključne riječi: funkcija desnog srca, hemodijaliza, Tei indeks, odnos E/E' Adresa autora: Doc. dr Tamara Kovačević-Preradović Ul. 12 beba bb,

“…2) In previous reports, assessment of right ventricular (RV) function has been shown to be important under several clinical conditions, such as acute pulmonary embolism (PE), valvular diseases, and congenital heart disease, as well as after cardiac surgery. [3][4][5][6] RV dysfunction in patients with left-sided HF has also been shown to be associated with an adverse outcome in a small series of patients with symptomatic HF, but studies of RV systolic function as a risk factor are challenging as a result of a lack of clinically applicable methods for the evaluation of RV performance. [1][2][3][7][8][9][10][11][12][13] Echocardiography remains the mainstay for the diagnosis of a variety of cardiac structural and hemodynamic abnormalities.…”

Prognostic Significance of Right Ventricular Dimension on Acute Decompensation in Chronic Left-Sided Heart Failure

SummaryRight ventricular (RV) dysfunction has been discussed in relation to an adverse outcome in heart failure (HF). The aim of this study was to analyze the relationship between RV function with HF exacerbation and its subsequent longterm outcome in patients with chronic left-sided HF.We studied 122 consecutive patients who were admitted for dyspnea due to exacerbated left-sided HF with a left ventricular (LV) ejection fraction of less than 40%. Conventional echocardiography was performed in the study subjects on admission and at discharge. Cox proportional hazards analysis revealed that RV end-diastolic dimension (RVDd) (hazard ratio 1.131, P = 0.005, 95% confidence interval 1.039-1.231) and the serum level of creatinine on admission were independent predictors of subsequent cardiac-related death, but RVDd at discharge and other LV parameters were not. Thus, patients were divided into tertiles on the basis of RVDd on admission: < 32 mm (n = 37), 32-40 mm (n = 43), and ≧ 40 mm (n = 42). According to the increase in the RVDd category, the cardiac-related death-free rate significantly decreased. Among the 3 groups, the pulse pressure and serum total bilirubin levels that demonstrated low cardiac output syndrome (LOS) parameters had significant differences.RVDd on admission could be measured noninvasively and easily to predict a worse long-term prognosis of chronic left-sided HF on admission, and showed correlations with LOS parameters.

“…RV long -axis function was recorded from the apical four-chamber view with the M-mode cursor positioned at the free wall angle of the tricuspid valve annulus. Total RV long -axis excursion amplitude was taken from end-systole to end-diastole (13 For assessment of the degree of enlargement of the RV, the RV end-diastolic diameter (RVEDD) was indexed to the LV enddiastolic diameter (LVEDD), finally given as RV dilatation index (RVDI=RVEDD/LVEDD). RV size was classified as normal when RVDI was equal or less than 0.5 (24).…”

Relationship between ventricular function assessed by tissue Doppler imaging and exercise capacity in patients after repair of tetralogy of Fallot: an observational study ABSTRACTObjective: The present study aims to study the relationship between tissue Doppler echocardiography (TDE) indices of right ventricle and exercise capacity in patients after total correction for tetralogy of Fallot (ToF). Methods: This cross-sectional observational study included 20 patients, after undergoing total correction procedure for ToF diagnosed with mild/moderate pulmonary regurgitation and 30 age-matched healthy children. In the postoperative period, patients were invited to hospital for evaluation of the ventricular functions by 2D, M-mode, Doppler (DE) echocardiography and TDE and exercise testing to evaluate the effort capacity. Statistical analysis was performed using Mann-Whitney U and Chi-square tests, and Pearson correlation analysis. Results: Compared with the controls; the mitral annular peak systolic flow velocity (Sm) value was significantly lower, while isovolumic contraction time (IVCT), isovolumic relaxation time (IVRT) and myocardial performance index (MPI) values obtained at the tricuspid and mitral (MV) valves were significantly higher (p<0.05 for all) in patients after ToF repair. There was a negative correlation between the exercise period and the total correction age (r=-0.20, p=0.015) and the same negative correlation existed between the exercise period and METS (r=-0.25, p=0.010). MV IVCT with DE and TDE was found to be correlated with METS (r=-0.45, p=0.04). Left ventricular MPI was found to be correlated with maximum heart rate (r=-0.20, p=0.03). By DE, tricuspid valve deceleration time and Sm peak flow velocity with TDE were significantly correlated with METS (r=-0.30, p=0.04; r=-025, p=0.005, respectively). MPI calculated with TDE was correlated with maximum heart rate (r=-0.15, p<0.01). Conclusion: Even if patients, undergone total correction surgery for ToF were asymptomatic or had minimal clinical symptoms, MPI index assessed by pulse wave TDE and exercise testing may allow early diagnosis of right ventricle dysfunction. Yöntemler: Enine kesitli-gözlemsel çalışmaya, Fallot Tetralojisi tanısı ile tam düzeltme operasyonu uygulanmış, hafif-orta derecede pulmoner regürjitasyonu olan 20 hasta ile kontrol grubu olarak 30 sağlıklı çocuk dahil edildi. Hastalar, ameliyat sonrası dönemde 2D, M mod, Doppler ekokardiyografi ve doku Doppler ekokardiyografi ile ventrikül fonksiyonları, egzersiz testi ile efor kapasiteleri değerlendirilmek üzere hastaneye çağrılmıştır. İstatistiksel analiz Mann-Whitney U ve Ki-kare testi ve Pearson korelasyon analizi ile yapıldı. Bulgular: Kontrol grubu ile karşılaştırıldığında, Fallot tetralojili hasta grubunda mitral annüler pik sistolik akım hız (Sm) değeri belirgin olarak düşük, triküspit ve mitral (MV) kapaktan elde edilen izovolümik relaksasyon zamanı (IVRT), izovolümik kontraksiyon zamanı (IVCT) ve miyokart performans indeksi (MPI) değerleri daha yüksek idi (tümü için p<0....
