“…4,5) The TAPSV, measured by pulsed wave-TDI, has become an index for right ventricular systolic function in children. [6][7][8] However, a cut-off TAPSV value as a predictor of impaired right ventricular systolic function in children is a controversial topic. Previous studies reported that a TAPSV < 11.5 cm/s or < 10.5 cm/s was able to predict impaired right ventricular systolic function.…”

“…5) TAPSV, measured by pulsed wave-tissue Doppler imaging (pulsed wave-TDI), has been suggested as a good quantitative parameter of right ventricular systolic function in children. [6][7][8] A few more recent studies have shown that TAPSV may be a reproducible index of right ventricular systolic function in patients with corrected congenital heart disease, 9) including repaired TOF. 10) Thus far, few reports have focused on evaluating risk factors for late right ventricular systolic dysfunction after correction of TOF through non-invasive examination.…”

SummaryTo evaluate independent risk factors for late right ventricular systolic dysfunction after correction of Tetralogy of Fallot (TOF) in a single-centre, retrospective and observational clinical trial.Patients less than 3 years of age who underwent correction of TOF and subsequently routine clinical follow-up of more than 36 months were included in this study and were divided either into an experimental group (right ventricular systolic dysfunction) or a control group (normal right ventricular systolic function) according to the tricuspid annular peak systolic velocity (TAPSV) value measured by pulsed wave-tissue Doppler imaging (pulsed wave-TDI). The relevant data of all selected patients were investigated and analyzed.From January 2012 to December 2012, a total of 113 consecutive eligible patients were enrolled in this study and were divided either into an experimental group (n = 41) or control group (n = 72). Through univariate analysis and subsequent logistic regression, low preoperative arterial oxygen saturation (OR = 1.66, 95%CI 1.22-4.58, P = 0.0163), age less than 6 months at the time of surgery (OR = 3.45, 95%CI 1.87-9.17, P = 0.0021), and transannular patch (OR = 2.15, 95%CI 1.31-5.38, P = 0.0015) were 3 independent risk factors for late right ventricular systolic dysfunction after correction of TOF.This clinical trial suggested low preoperative arterial oxygen saturation was associated with late right ventricular systolic dysfunction after correction of TOF, and appropriate age at the time of surgery and selection of a proper surgical method to reconstruct the right ventricular outflow tract contributed to improving late right ventricular systolic function in pediatric patients with repaired TOF.

“…Geleneksel ekokardiyografi yöntemleri ile ölçülebilen ejeksiyon fraksiyonu (EF) ve miyokart performans indeksi (MPİ) ventriküllerin fonksiyonlarını göstermede oldukça değerlidir. Son yıllarda, doku Doppler ekokardiyografi tekniğinin çocuklarda kullanımının yaygınlaşması ile MPİ bu teknik ile ölçül-meye başlanmıştır (5)(6)(7)(8)(9).

ÖZETAmaç: Çalışmanın amacı; hipoksik iskemik ensefalopatili (HİE) ve sağlıklı term yenidoğan bebeklerde, kardiyak etkilenmeyi göstermek amacı ile pulsed (PD) ve doku Doppler (DD) tekniklerini kullanarak miyokart performans indeksini (MPİ/Tei indeksi) belirlemek ve bu iki teknik sonuçları arasında ortaya çıkan farklılıkları değerlendirmektir. Yöntemler: Çalışma prospektif gözlemsel bir çalışmadır. Postnatal ilk 24 saat içinde belirlenen kriterlere göre perinatal asfiksi tanısı konulan 20 term yenidoğan ve kontrol grubu olarak sağlıklı, 50 term yenidoğan bebek çalışmaya alındı. HİE grup Sarnat evrelemesine göre Sarnat Evre 1 ve 2-3 olmak üzere iki gruba ayrıldı. Kontrol ve hasta gruplarına doğumdan sonraki ilk 24 saat içerisinde ve bir yıl sonra, PD ve DD ekokardiyografi teknikleri uygulanarak MPI hesaplandı. Aynı ölçüm teknikler ile elde edilen veriler Kruskal-Wallis testi ile iki tekniğin birbirine üstünlüğü ise Z skoru olarak hesaplandı. Bulgular: Sarnat evre 2-3 grubunda, hayatın ilk gününde her iki ventrikülde PD (0.41±0.04, 0.51±0.02) ve DD (0.59±0.04, 0.51±0.02) ile bakılan bakılan MPİ kontrol grubuna göre anlamlı derecede yüksek bulundu (p<0.01, p<0.02, p<0.03). Pulsed ve doku Doppler ile elde edilen MPİ için hesaplanan Z skoru, kontrol grubu ve Sarnat Evre 1 grubunda her iki ventrikül için benzer bulunurken, diğer Sarnat gruplarında anlamlı olarak farklı olduğu görüldü. Sonuç: Hipoksik iskemik ensefalopatili yenidoğanlarda kardiyak fonksiyonlar olumsuz yönde etkilenmekte olup bu durumun, hipoksinin ağırlığı ile ilişkili olduğu bulunmuştur. MPİ, hafif hipoksiye maruz kalan yenidoğanlarda kontrol grubundan farksız iken, orta ve ağır hipoksiye maruz kalmış yenidoğanlarda daha büyüktür. İki tekniğin ölçüm değerleri açısından birbirine üstünlüğü bulunamamış ancak orta ve ağır hipoksik grupta DD ile elde edilen MPİ'deki Z skor değişiminin daha büyük olduğu saptanmıştır. ABSTRACTObjective: The aim of the study is determination of myocardial performance index (MPI/Tei index) using pulsed (PD) and tissue Doppler (TD) techniques to show cardiac response in newborns with hypoxic-ischemic encephalopathy (HIE) and healthy newborns and eventually evaluation of the differences between these two techniques. Methods: The study is a prospective observational study. Twenty term newborns diagnosed as perinatal asphyxia during postnatal 24 hours due to the defined criteria and fifty healthy term neonates as control group were included the study. Hypoxic group was divided into two groups with Sarnat stages, Sarnat Stage 1 and 2-3. MPIs (Tei indexes) were calculated with PD and TD echocardiographic techniques in all groups after the 24 hours of birth and one year later. The statistical differences between same techniques were calculated with Kruskal-Wallis test and Z score was used to compare the superiority of two techniques. Results: The MPI values calculated by PD (0.41±0.04, 0.51±0.02) and TD (0.59±0.04, 0.51±0.02) during the first day of life in Sarnat Stage 2-3 in both ventricles were significantly higher than the contro...

“…2 Tissue Doppler echocardiography (TDE) offers a non-invasive quantitative method of assessing longitudinal systolic and diastolic ventricular performance by measuring velocities directly from the myocardium. [3][4][5] While a few studies have described cardiovascular involvement among adults with OI, there is very little data available for paediatric patients. 6,7 To the best of the authors' knowledge, this is the first study assessing cardiovascular abnormalities, particularly systolic and diastolic function, in paediatric patients with OI using both conventional and TDE techniques.…”

abstract:Objectives: Structural and functional cardiovascular abnormalities have been reported in adults with osteogenesis imperfecta (OI); however, there is a lack of paediatric literature on this topic. This study aimed to investigate cardiovascular abnormalities in children with OI in comparison to a control group. Methods: This case-control study was conducted at the Sultan Qaboos University Hospital in Muscat, Oman, between May 2013 and August 2014. Data from eight patients with OI and 24 healthy controls were compared using conventional and tissue Doppler echocardiography (TDE). Results: The OI group had significantly lower peak early mitral valve flow velocity (P = 0.027), peak a-wave reversal in the pulmonary vein (P = 0.030) and peak early diastolic velocity of the mitral valve and upper septum (P = 0.001 each). The peak late diastolic velocities of the mitral valve (P = 0.002) and the upper septum (P = 0.037) were significantly higher in the OI group; however, the peak early/late diastolic velocity ratios of the mitral valve (P = 0.002) and upper septum (P = 0.001) were significantly lower. Left ventricular dimensions and aortic and pulmonary artery diameters were larger in the OI group when indexed for body surface area. Both groups had normal systolic cardiac function. Conclusion: Children with OI had normal systolic cardiac function. However, changes in myocardial tissue Doppler velocities were suggestive of early diastolic cardiac dysfunction. They also had increased left ventricular dimensions and greater vessel diameters. These findings indicate the need for early and detailed structural and functional echocardiographic assessment and follow-up of young patients with OI.
