A jobbkamra-funkció vizsgálata veleszületett szívfejlődési rendellenességekben különösen nehéz, főleg a posztoperatív időszakban, a jobb kamra sajátos geometriai alakzata miatt, ugyanakkor kiemelkedő a jelentősége a komplex szívfejlődési rendellenességek nyomon követésében. A posztoperatív jobbkamra-diszfunkció fontos tényező a mortalitásban és morbiditásban és a reoperáció szükségességének meghatározásában. Ez idáig gyermekekben 133 szívszöveti Doppler-vizsgálat történt, a betegek életkora 14 nap – 20 év, az átlagéletkor 12,4 év volt. A jelen közleményben a szerző a jobb kamrára vonatkozó vizsgálatokat ismerteti. A szisztémás jobbkamra-funkció értékelésére nagyér-transpositiós betegek Senning-műtétje utáni (1. betegcsoport, 17 beteg 21 vizsgálata), illetve Fallot-tetralógia-műtét utáni (2. betegcsoport, 21 beteg) vizsgálatok történtek. Módszer: A szöveti sebességek közül a jobb kamrai (tricuspidalis anulus) szisztolés sebességet és kora diasztolés sebességet E’ és a tricuspidalis beáramlási flow E-hullám-sebességet, illetve az E/E’ arányát mérte. E sebességek egészségestől való eltérését, illetve a szív mágnesesrezonancia-vizsgálattal mért jobb kamrai ejekciós frakció közötti összefüggését vizsgálta. Eredmények: Az 1. betegcsoportban a szisztolés sebesség szignifikánsan eltért az egészségeseknél mért értéktől: 9,3–3,7 cm/s sv vs. 14,2 ± 2,3 cm/s ( p > 0,001), E’: 12,8 ± 4,7 cm/s vs. 16,7 ± 2,8 cm/s, E/E’ 7,2 ± 4,6 vs. 3,7 ± 1,4. A szisztolés szöveti Doppler-sebesség és E/E’ arány szoros összefüggést mutatott a szív mágneses rezonanciával mért ejekciós frakciójával ( p > 0,001). A 2. betegcsoport szisztolés értéke kevésbé, de szintén, szignifikánsan csökkent volt. 11,1 ± 4,3 cm/s és a jobb kamrai szív mágneses rezonanciával mért ejekciósfrakció-értékkel szintén szignifikáns összefüggést mutatott ( p > 0,001). Konklúzió: Az eredmények szerint a szöveti Doppler-technika a jobbkamra-funkció vizsgálatára alkalmas veleszületett szívbetegségekben és a jobb kamrai funkció noninvazív módszerei közé ajánlatos beiktatni. Kellő gyakorlattal – a szív mágnesesrezonancia-vizsgálatával együtt alkalmazva – fontos, megbízható adatok nyerhetők a betegek nyomon követésében, ami komoly segítség lehet a posztoperatív döntéshozatalban, például az esetleges reoperáció szükségességének megítélésében és a késői posztoperatív prognózis meghatározásában.

AbstractBackgroundNewer echocardiographic techniques may allow for more accurate assessment of right ventricular function. Adult studies have correlated these echocardiographic measurements with invasive data, but minimal data exist in the paediatric congenital heart population. The purpose of this study was to evaluate echocardiographic measurements that correlate best with right ventricular systolic and diastolic catheterisation parameters.MethodsPatients with two-ventricle physiology who underwent simultaneous echocardiogram and cardiac catheterisation were included in this study. Right ventricular systolic echocardiographic data included fractional area change, displacement, tissue Doppler imaging s’ wave, global longitudinal strain, and strain rate s’ wave. Diastolic echocardiographic data included tricuspid E and A waves, tissue Doppler imaging e’ and a’ waves, and strain rate e’ and a’ waves. E/tissue Doppler imaging e’, tissue Doppler imaging e’/tissue Doppler imaging a’, E/strain rate e’, and strain rate e’/strain rate a’ ratios were also calculated. Catheterisation dP/dt was used as a marker for systolic function and right ventricular end-diastolic pressure for diastolic function.ResultsA total of 32 patients were included in this study. The median age at catheterisation was 3.1 years (0.3–17.6 years). The DP/dt was 493±327 mmHg/second, and the right ventricular end-diastolic pressure was 7.7±2.4 mmHg. There were no significant correlations between catheterisation dP/dt and systolic echocardiographic parameters. Right ventricular end-diastolic pressure correlated significantly with strain rate e’ (r=−0.4, p=0.02), strain rate a’ (r=−0.5, p=0.03), and E/tissue Doppler imaging e’ (r=0.4, p=0.04).ConclusionCatheterisation dP/dt did not correlate with echocardiographic measurements of right ventricular systolic function. Strain rate and tissue Doppler imaging analysis significantly correlated with right ventricular end-diastolic pressure. These values should be further studied to determine whether they may be used as an alternative method to estimate right ventricular end-diastolic pressure in this patient population.

Rv Function

Transthoracic echocardiography (TTE) is the first-line tool for diagnosis and followup of pediatric and young adult patients with congenital heart disease (CHD). Appropriate use of TTE can reduce the need for more invasive modalities, such as cardiac catheterization and cardiac magnetic resonance imaging. New echocardiographic techniques have emerged more recently: tissue Doppler imaging, tissue tracking (strain and strain rate), vector velocity imaging (VVI), myocardial performance index, myocardial acceleration during isovolumic acceleration (IVA), the ratio of systolic to diastolic duration (S/D ratio), and two dimensional measurements of systolic right ventricular (RV) function (e.g., tricuspid annular plane systolic excursion, TAPSE). These may become valuable indicators of ventricular performance, compliance, and disease progression. In addition, three-dimensional (3D) echocardiography when performed for the assessment of valvular function, device position, and ventricular volumes is being integrated into routine clinical care. In this paper, the potential use and limitations of these new echocardiographic techniques in patients with CHD are discussed. A particular focus is on the echocardiographic assessment of right ventricular (RV) function in conditions associated with increased right ventricular volume (e.g., pulmonary regurgitation after tetralogy of Fallot repair) or pressure (e.g., pulmonary hypertension) in children and young adults.

Rv Function

Abstract Background Right ventricular (RV) function is recognized as a prognostic factor in congenital heart disease (CHD). The accuracy of established parameters as tricuspid annular plane systolic excursion (TAPSE), right ventricular fractional area change (RVFAC) and tissue Doppler imaging (TDI S') are limited as the parameters reflect only a limited region of the RV. We previously introduced a novel four-view approach with different RV walls visualized in their long axis from one apical view using 2D-transthoracic echocardiographic (TTE) iRotate mode. Aims To extensive evaluate the entire RV function using iRotate echocardiography in a whole spectrum of CHD patients with abnormally loaded RV; both feasibility and RV echocardiographic parameters as comparison with healthy subjects is evaluated. Methods and results One hundred and forty-two CHD patients with abnormally loaded RV and 89 healthy subjects were included. All subjects underwent complete TTE with evaluation of TAPSE, TDI S' and peak systolic global longitudinal RV strain (RV-GLS) from the RV walls using the four-view iRotate model. The feasibility of TAPSE and RV S' ranged between 94% and 100%. The feasibility of RV-GLS in CHD was 98%, 69%, 87% and 72% respectively in the lateral, anterior, inferior and inferior coronal view walls. With the exception of RV S' in the inferior coronal view, all parameters were significantly lower in the CHD vs healthy subjects (p<0.001) (Table). i-Rotate RV wall GLS (%) RV wall GLS (%) Measurement Feasibility Congenital (n=142) Controls (n=89) P-value Lateral 97.9 −17.6±5.0 −25.4±4.5 <0.001 Anterior 69.0 −15.9±4.9* −24.2±4.5 <0.001 Inferior 88.7 −17.2±4.7 −23.3±4.4 <0.001 Inferior coronal view 72.5 −15.1±4.5* ** −20.8±5.2 <0.001 Data expressed as mean ± SD or %. p<0.05 for *Lateral vs Anterior and vs Inferior CV; **Inferior vs Inferior CV. Conclusion The feasibility of all RV parameters in the four-axis iRotate model is excellent in CHD and represents a reproducible, easily applicable and complete RV assessment in daily practice. RV function is significantly decreased in the CHD group using both load dependent and independent parameters. Complete RV strain analysis reveals regional differences in patients with CHD.
