Abstract
BACKGROUND In childhood cancer survivors (CCSs) anthracycline-related cardiotoxicity is an important cause of morbidity and late mortality, but the optimal modality of cardiac surveillance still remains to be defined. The aim of this study was to assess whether non-invasive echocardiography-based functional cardiac measures can detect early subclinical myocardial changes in long-term pediatric cancer survivors who received anthracycline therapy. METHODS Twenty anthracycline-treated long-term CCSs and 20 age, sex, and body surface area matched healthy controls were enrolled in this study. Among cancer survivors, mean age at diagnosis was 6.5 ± 4.4 years, and the mean cumulative anthracycline dose was 234.5 ± 87.4 mg/m2. All subjects underwent a comprehensive functional echocardiographic protocol study including two-dimensional echocardiography (2D Echo), tissue Doppler imaging (TDI), speckle tracking (STE) and three-dimensional echocardiography (3D Echo). Patients were studied at a mean follow-up time of 6.5 ± 2.8 years from the end of therapy. RESULTS No significant differences in two-dimensional left ventricle ejection fraction (LVEF), diastolic parameters and speckle tracking (STE)-derived myocardial strain were observed between patients treated with anthracyclines and controls. Myocardial performance index was significantly prolonged (p = 0.005) and three-dimensional LVEF was significantly reduced (p = 0.002) in CCSs compared to controls, even though most values were within the normal range. There were no significant correlations between 2D, STE, and 3D echocardiographic parameters and age at diagnosis or duration of follow-up. No significant differences in echocardiographic parameters were found when stratifying cancer patients according to established risk factors for anthracycline cardiomyopathy. CONCLUSIONS This study found significantly reduced three-dimensional LVEF in CCSs compared with controls, despite no significant differences in two-dimensional LVEF and longitudinal strain values. These findings suggest that long-term CCSs who had received anthracycline therapy may be found to have subclinical features of myocardial dysfunction. However, further studies are needed to demonstrate the validity of new imaging techniques, including STE and 3D Echo, to identify patients at risk for cardiomyopathy in the long-term follow-up of CCSs.

Abstract
Objectives The purpose of this study was to assess the timing of changes in serial echocardiographic parameters in pediatric cancer survivors and to evaluate their associations with cardiomyopathy development. Background Pediatric cancer survivors undergo serial echocardiograms to screen for cardiotoxicity. It is not clear whether small longitudinal changes in functional or structural parameters over time have clinical significance. Methods This is a multicenter, retrospective, case-control study of ≥1-year survivors following the end of cancer therapy. Cardiomyopathy cases (fractional shortening [FS] ≤28% or ejection fraction [EF] ≤50% on ≥2 occasions) were matched to control subjects (FS ≥30%, EF ≥55%, not on cardiac medications) by cumulative anthracycline and chest radiation dose, follow-up duration, and age at diagnosis. Digitally archived clinical surveillance echocardiograms were quantified in a central core laboratory, blinded to patient characteristics. Using mixed models with interaction terms between time and case status, we estimated the least square mean differences of 2-dimensional, M-mode, pulsed wave Doppler, and tissue Doppler imaging–derived parameters over time between cases and control subjects. Results We identified 50 matched case-control pairs from 5 centers. Analysis of 412 echocardiograms (cases, n = 181; control subjects, n = 231) determined that indices of left ventricular systolic function (FS, biplane EF), diastolic function (mitral E/A ratio), and left ventricular size (end-diastolic dimension z-scores) were significantly different between cases and control subjects, even 4 years prior to the development of cardiomyopathy. Conclusions Longitudinal changes in cardiac functional parameters can occur relatively early in pediatric cancer survivors and are associated with the development of cardiomyopathy.

Abstract
BACKGROUND Leukemia is the most common pediatric malignancy. It affects bone marrow cells especially lymphoid cell precursor. Leukemia is treated mainly by chemotherapy. Doxorubicin is a well-established chemotherapeutic agent included in treatment protocols of acute lymphoblastic leukemia. Its efficacy is often limited by its cardiotoxic side effects. Many studies are directed to overcome this problem. Black seed oil was found to have a potent cardioprotective effect.Aim of the study: To assess the protective role of black seed oil against doxorubicin-induced cardiotoxicity in children with acute lymphoblastic leukemia. SUBJECTS AND METHODS This study was carried out on 40 children with acute lymphoblastic leukemia including 20 patients under doxorubicin therapy and black seed oil 80 mg/kg/dose divided into 3 doses starting at the same moment of beginning of doxorubicin infusion therapy and continued for 1 week after each doxorubicin dose [group I] and 20 patients under doxorubicin and placebo for 1 week after each doxorubicin dose [group II]. They underwent conventional echo-Doppler measures of left ventricular systolic and diastolic functions and pulsed wave tissue Doppler of lateral mitral annulus. RESULTS No significant differences were found in parameters of electrocardiograph including S-T segment and Q-T interval either before or after doxorubicin therapy. No significant differences in echocardiographic parameters were found between group I and group II before therapy. Non-significant changes in parameters of diastolic function [E/A ratio or e/a ratio] were found after doxorubicin therapy in group I and II, but there were significant reduction in parameters of systolic function [EF, FS and s wave] after doxorubicin therapy more in group II than group I.Conclusion and recommendation: From this study, we concluded that: Black seed oil improves some cardiac side effects of doxorubicin as shown by better systolic functions in children with acute lymphoblastic leukemia who were treated with Doxorubicin and black seed (group I) than in children with acute lymphoblastic leukemia who were treated with doxorubicin alone with no black seeds (group II), and therefore multi center studies is recommended to be done before we can recommend the use of black seed oil as an adjuvant therapy in patients with acute lymphoblastic leukemia under doxorubicin-based treatment protocol.

Abstract
PURPOSE OF REVIEW The anthracycline (AC) group of drugs is widely used for cancer chemotherapy and has improved outcomes in many childhood malignancies. However, cardiovascular complications are major causes of morbidity and mortality in AC recipients, with the greatest risk factor being a higher cumulative dosage. The purpose of this review is to describe the etio-pathogenesis and risk factors of AC induced cardiotoxicity, with emphasis on currently available and emerging modalities of non-invasive imaging in its surveillance, and to review guidelines on its prevention and treatment. RECENT FINDINGS Presently, ejection fraction and shortening fraction derived from two-dimensional echocardiography are the most widely used parameter for monitoring of cardiac function in childhood cancer survivors. The newer speckle tracking echocardiography has shown potential to detect abnormalities in ventricular function prior to the conventional measures such as ejection fraction and shortening fraction. When available, three-dimensional echocardiography should be used as it allows for more accurate estimation of ejection fraction. Newer magnetic resonance imaging (MRI) techniques, such as delayed enhancement and T1 mapping, are useful adjuncts for cardiac evaluation in cancer survivors, especially in patients with poor echocardiographic windows. Early detection and management of cardiovascular diseases is one of the major goals in the long-term follow-up of childhood cancer survivors. In addition to conventional two-dimensional echocardiography, newer techniques such as speckle tracking echocardiography and three-dimensional echocardiography should be incorporated due to its ability to detect early changes in anthracycline-induced cardiotoxicity. However further research are needed to guide changes in management due to abnormalities in speckle tracking echocardiography.

Abstract
Objective: Speckle tracking echocardiography (STE) enables global and regional evaluation of the left ventricle (LV); therefore, it is the most useful method for detecting subclinical dysfunction in patients exposed to cardiotoxic agents. A novel technique triplane (3P) echocardiography also allows single beat assessment of LV global longitudinal strain values. We firstly aimed to demonstrate both two-dimensional (2D)- and 3P-STE-derived LV global longitudinal strain measurements in children after anthracycline exposure. Methods: This study included 23 cross-sectionally enrolled asymptomatic pediatric cancer patients who received anthracycline chemotherapy and 17 healthy controls matched by age, gender, and body surface area. All subjects underwent detailed 2D, Doppler, 2D-STE, and 3P-STE for assessment of LV function. The patients had received a median cumulative dose of 150 mg/m2. Results: 1. From “Pulsed” Doppler-based measurements, only pulmonary vein flow ratio showed a significant difference between the groups. 2. When measurements were taken from the interventricular septum, the patients’ ejection time values decreased significantly and their myocardial performance index values increased significantly; when the measurements were taken from the LV free wall, the peak systolic velocities showed a statistically significant difference. 3. Both 2D- and 3P-STE-derived longitudinal myocardial deformation values of LV were lower in the patient group. 4. 2D-STE-derived LV circumferential strain values were decreased in the patient group, whereas radial strain values were not significantly different compared with matched controls. Conclusion: Using Doppler and 2D- and 3P-STE methods, this study confirmed the subclinical LV dysfunction in patients after anthracycline exposure.

Abstract
UNLABELLED Longitudinal motion significantly contributes to the contraction of the ventricles. We studied the left (LV) and right ventricular (RV) longitudinal functions in 75 anthracycline-exposed, long-term childhood cancer survivors and 75 healthy controls with conventional echocardiography, tissue Doppler imaging (TDI), speckle tracking echocardiography (STE) of the mitral and tricuspid annular motion, and real-time three-dimensional echocardiography (RT-3DE). Cardiac magnetic resonance (CMR) imaging was performed on 61 of the survivors. The survivors had lower systolic myocardial velocities in the LV and lower diastolic velocities in both ventricles by TDI than did their healthy peers. The STE-based tissue motion annular displacement (TMAD) values describing the LV and RV systolic longitudinal function (MAD and TAD mid%, respectively) were also lower among the survivors (15.4 ± 2.4 vs. 16.1 ± 2.2 %, p = 0.049 and 22.5 ± 3.0 vs. 23.5 ± 3.0 %, p = 0.035). MAD and TAD mid in millimeters correlated with the respective ventricular volumes measured with RT-3DE or CMR. CONCLUSION Childhood cancer survivors exposed to low to moderate anthracycline doses had decreased longitudinal systolic and diastolic functions (TDI or STE) compared with healthy controls. The STE-based TMAD is a fast and reproducible method to assess cardiac longitudinal function. What is Known? • High anthracycline doses cause LV dysfunction as evidenced by a decreased ejection fraction. What is new? • Low to moderate anthracycline doses also have a negative impact on the LV and RV longitudinal systolic and diastolic function. • TMAD is a new and fast method to assess the cardiac longitudinal function after anthracycline exposure.

Abstract
BACKGROUND This review update has been managed by both the Childhood Cancer and Cochrane Gynaecological, Neuro-oncology and Orphan Cancer Groups.The use of anthracycline chemotherapy is limited by the occurrence of cardiotoxicity. To prevent this cardiotoxicity, different anthracycline dosage schedules have been studied. OBJECTIVES To determine the occurrence of cardiotoxicity with the use of different anthracycline dosage schedules (that is peak doses and infusion durations) in people with cancer. SEARCH METHODS We searched the databases of the Cochrane Register of Controlled Trials (CENTRAL) (the Cochrane Library, Issue 11, 2015), MEDLINE (1966 to December 2015), and EMBASE (1980 to December 2015). We also searched reference lists of relevant articles, conference proceedings, experts in the field, and ongoing trials databases. SELECTION CRITERIA Randomised controlled trials (RCTs) in which different anthracycline dosage schedules were compared in people with cancer (children and adults). DATA COLLECTION AND ANALYSIS Two review authors independently performed the study selection, the 'Risk of bias' assessment, and data extraction. We performed analyses according to the guidelines of the Cochrane Handbook for Systematic Reviews of Interventions. MAIN RESULTS We identified 11 studies: 7 evaluated different infusion durations (803 participants), and 4 evaluated different peak doses (5280 participants). Seven studies were RCTs addressing different anthracycline infusion durations; we identified long-term follow-up data for one of the trials in this update. The meta-analysis showed a statistically significant lower rate of clinical heart failure with an infusion duration of six hours or longer as compared to a shorter infusion duration (risk ratio (RR) 0.27; 95% confidence interval 0.09 to 0.81; 5 studies; 557 participants). The majority of participants included in these studies were adults with different solid tumours. For different anthracycline peak doses, we identified two RCTs addressing a doxorubicin peak dose of less than 60 mg/m(2) versus 60 mg/m(2) or more, one RCT addressing a liposomal doxorubicin peak dose of 25 mg/m(2) versus 50 mg/m(2), and one RCT addressing an epirubicin peak dose of 83 mg/m(2) versus 110 mg/m(2). A significant difference in the occurrence of clinical heart failure was identified in none of the studies. The participants included in these studies were adults with different solid tumours. High or unclear 'Risk of bias' issues were present in all studies. AUTHORS' CONCLUSIONS An anthracycline infusion duration of six hours or longer reduces the risk of clinical heart failure, and it seems to reduce the risk of subclinical cardiac damage. Since there is only a small amount of data for children and data obtained in adults cannot be extrapolated to children, different anthracycline infusion durations should be evaluated further in children.We identified no significant difference in the occurrence of clinical heart failure in participants treated with a doxorubicin peak dose of less than 60 mg/m(2) or 60 mg/m(2) or more. Only one RCT was available for the other identified peak doses, so we can make no definitive conclusions about the occurrence of cardiotoxicity. More high-quality research is needed, both in children and adults and in leukaemias and solid tumours.

Abstract
The aim of this study was to determine the effect of induction dose of anthracycline chemotherapy on the biventricular function among children with acute hematological malignancies (AHM) using tissue Doppler imaging (TDI) and 2D speckle tracking echocardiography (2D-STE). Thirty pediatric patients with AHM and a mean age of 9.24 ± 4.14 years performed conventional echocardiography, TDI and 2D-STE. After induction chemotherapy, the RV showed mainly a diastolic alteration in its function manifested in significant reduction in the tricuspid TDI-derived E' and E'/A' ratio compared with the baseline (20.40 ± 3.81 vs. 17.47 ± 3.87 cm/s, p = 0.001, 1.29 ± 0.27 vs. 1.03 ± 0.37, p < 0.01, respectively), while the TDI-derived RV MPI and isovolumetric relaxation time of RV were significantly increased (0.32 ± 0.06 vs. 0.36 ± 0.08, p < 0.01, 24.73 ± 8.62 vs. 28.47 ± 11.51 ms, p < 0.05, respectively). The LV showed post-chemotherapy mainly an alteration in its longitudinal systolic function in the form of a reduction in MAPSE (13.61 ± 2.00 vs. 11.95 ± 1.75 mm; p < 0.001), TDI-derived systolic velocity of lateral mitral annulus (10.98 ± 2.34 vs. 10.03 ± 1.83 cm/s, p < 0.05), 2D-STE-derived global longitudinal strain (-21.58 ± 2.54 vs. -19.18 ± 3.59 %, p = 0.001) and 2D-STE-derived global longitudinal strain rate (-1.76 ± 0.22 vs. 1.55 ± 0.29 1/s, p < 0.05), with preservation of LV diastolic function when compared to baseline. TDI and 2D-STE could be used for early detection of anthracycline-induced cardiotoxicity in the pediatric age group. Early after induction chemotherapy, the RV develops mainly diastolic dysfunction, while the LV showed a relative longitudinal systolic impairment.

Abstract
Anthracycline chemotherapy (AC) is associated with impaired left ventricular (LV) systolic function. LV ejection fraction (EF %) obtained by two-dimensional echocardiography is the current gold standard for detection and monitoring of LV systolic function. However, dependence on LVEF has been shown to be unreliable due to its inherent limitations. Speckle tracking echocardiography (STE) measures myocardial strain and is a sensitive method to detect LV systolic dysfunction with demonstrated utility in such detection in adult and pediatric cohort studies. Compare myocardial strain indices derived by STE with LVEF to detect ACT-induced LV systolic dysfunction. Prospective, cross-sectional measurements of LV myocardial strain indices derived from STE with LVEF. Pediatric cohort of 25 patients (pts): 17 females, eight males with a mean age 9.8 ± 5.8 years, who received anthracyclines (AC); median cumulative dose ≥150 ± 124.4 mg/m(2), range 60-450 mg/m(2) showing normal LV end-diastolic diameter (mm) and normal LVEF (≥55 %) underwent STE to obtain LV myocardial strain indices: strain and strain rate. The inter- and intraobserver variability for the strain indices was 5 %. Fifteen of 25 pts (60 %) showed abnormal global longitudinal peak systolic strain (GLPSS) and 19/25 pts (76 %) showed abnormal peak circumferential strain (PCS) compared to age-matched controls (p = 0.005). In contrast, no significant differences was observed in either indices with the dose of AC. Likewise, no significant changes in the systolic or diastolic strain rate were noted with the dose of AC (r (2) = 0.0076 for peak E, r (2) = 0.072 for peak A, p = NS). GLPSS and PCS were diminished and, however, correlated poorly with the cumulative dose of AC. These observations indicate an early onset of LV systolic dysfunction by the strain indices in pts who continue to show a normal LVEF implying presence of occult LV systolic dysfunction. These novel strain indices may assist in early detection of LV systolic dysfunction with implications for monitoring and prevention of AC-induced LV systolic dysfunction.

Abstract
BACKGROUND Anthracyclines are effective medications for childhood cancer. Their limitation is the risk of cardiomyopathy. Although diastolic dysfunction has been described in patients who received anthracyclines, cardiac monitoring has focused on systolic function, which is abnormal in up to 41% of the patients. We conducted a study to assess diastolic function utilising transmitral inflow Doppler velocities and tissue Doppler imaging in anthracycline-treated children 5 years post-therapy. METHODS This was a retrospective study on 63 anthracycline-treated patients. Echocardiographic parameters included peak early and late transmitral inflow Doppler velocities (E, A), E/A ratio, E deceleration time, and tissue Doppler imaging early and late diastolic mitral annulus velocities (E', A'), E/E' ratio, and E'/A' ratio. RESULTS All indices of diastolic function that we measured were normal in the anthracycline-treated patients. CONCLUSION We conclude that diastolic function assessed by transmitral inflow Doppler velocities and tissue Doppler imaging is normal in anthracycline-treated children 5 years after completion of treatment. Further longitudinal study is needed to determine whether diastolic function becomes abnormal with time in this patient population.

Abstract
In the US, children diagnosed with cancer are living longer, but not without consequences from the same drugs that cured their cancer. In these patients, cardiovascular disease is the leading cause of non-cancer-related morbidity and mortality. Although this review focuses on anthracycline-related cardiomyopathy in childhood cancer survivors, the global lifetime risk of other cardiovascular diseases such as atherosclerosis, arrhythmias and intracardiac conduction abnormalities, hypertension, and stroke also are increased. Besides anthracyclines, newer molecularly targeted agents, such as vascular endothelial growth factor receptor and tyrosine kinase inhibitors, also have been associated with acute hypertension, cardiomyopathy, and increased risk of ischemic cardiac events and arrhythmias, and are summarized here. This review also covers other risk factors for chemotherapy-related cardiotoxicity (including both modifiable and non-modifiable factors), monitoring strategies (including both blood and imaging-based biomarkers) during and following cancer treatment, and discusses the management of cardiotoxicity (including prevention strategies such as cardioprotection by use of dexrazoxane).

Abstract
PURPOSE Cardiovascular disease is the leading noncancer cause of death among survivors of childhood cancer. Ejection fraction (EF) and fractional shortening (FS) are common echocardiographic measures of cardiac function, but newer imaging modalities may provide additional information about preclinical disease. This study aimed to evaluate these modalities in detection of anthracycline-induced cardiac toxicity. METHODS We compared mean radial displacement, EF, and FS among 17 adult survivors of childhood cancer exposed to ≥ 300 mg/m(2) of anthracyclines to 17 age- and sex-matched healthy controls. Survivors with a history of cardiac-directed radiation, diabetes, or heart disease were excluded. RESULTS Survivors (35% male), mostly with history of treatment for a solid tumor, had a median age at diagnosis of 15 years (1-20) and 27 years (18-50) at evaluation. Median anthracycline exposure was 440 (range 300-645) mg/m(2). FS (35.5 vs. 39.6%, p < 0.01) and radial displacement (5.6 vs. 6.7 mm, p = 0.02) were significantly lower in survivors compared to controls, respectively. Although the mean EF was lower in survivors versus controls (55.4 vs. 59.7%), it was not statistically significant (p = 0.057). All echocardiographic measures were inversely associated with anthracycline dose, though radial displacement was no longer significantly correlated with anthracycline dose after controlling for survival time (p = 0.07), while EF remained correlated (p = 0.003). IMPLICATIONS FOR CANCER SURVIVORS Radial displacement, EF, and FS are lower in childhood cancer survivors compared to controls. In this study, radial displacement added no new information beyond the traditional measures, but clinical utility remains undetermined and requires further longitudinal study.

Abstract
BACKGROUND More than 50% of >270 000 childhood cancer survivors in the United States have been treated with anthracyclines and are therefore at risk of developing cardiotoxicity. Cardiac magnetic resonance (CMR) has demonstrated utility to detect diffuse interstitial fibrosis and changes in regional myocardial function. We hypothesized that CMR would identify occult cardiotoxicity characterized by structural and functional myocardial abnormalities in a cohort of asymptomatic pediatric cancer survivors with normal global systolic function. METHODS AND RESULTS Forty-six long-term childhood cancer survivors with a cumulative anthracycline dose ≥200 mg/m(2) and normal systolic function were studied 2.5 to 26.9 years after anthracycline exposure. Subjects underwent transthoracic echocardiography, CMR with routine cine acquisition, tissue characterization, and left ventricular strain analysis using a modified 16-segment model. Extracellular volume was measured in 27 subjects, all of whom were late gadolinium enhancement negative. End-systolic fiber stress was elevated in 45 of 46 subjects. Low average circumferential strain magnitude (εcc) -14.9±1.4; P<0.001, longitudinal strain magnitude (εll) -13.5±1.9; P<0.001, and regional peak circumferential strain were seen in multiple myocardial segments, despite normal global systolic function by transthoracic echocardiography and CMR. The mean T1 values of the myocardium were significantly lower than that of control subjects at 20 minutes (458±69 versus 487±44 milliseconds; P=0.01). Higher mean extracellular volume was observed in female subjects (0.34 versus 0.22; P=0.01). CONCLUSIONS Asymptomatic postchemotherapy pediatric patients have abnormal myocardial characteristics and strain parameters by CMR despite normal global cardiac function by standard transthoracic echocardiography and CMR measures.

Abstract
Cardiologists and oncologists today face the daunting challenge of identifying patients at risk for late-onset left ventricular (LV) systolic dysfunction from the use of various chemotherapeutic agents. Currently, the most widely used method in clinical practice for monitoring the potential of chemotherapy-induced cardiotoxicity is calculation of LV ejection fraction. The use of LV ejection fraction to determine whether to continue or discontinue the use of chemotherapeutic agents is limited, because decreases in LV ejection fraction frequently occur late and can be irreversible. These limitations have led to the exploration of diastolic function and newer modalities that assess myocardial mechanics to identify sensitive and specific variables that can predict the occurrence of late systolic function. The cancer therapies associated with cardiotoxicity are reviewed in this report. Additionally, the authors evaluate the role of present-day echocardiographic parameters, complementary noninvasive imaging modalities, and biomarkers in the prediction of cardiotoxicity. The authors address the evolving role of cardioprotective agents and potential therapies to prevent or reverse the progression of LV systolic dysfunction. Finally, they provide some ideas regarding future directions to enhance the knowledge of predicting late-onset LV systolic dysfunction secondary to cancer therapy.

Abstract
INTRODUCTION Late cardiotoxicity is a known complication of anthracycline therapy but the long-term effects of low cumulative doses are not well documented. We studied late cardiotoxicity in survivors of childhood acute lymphoblastic leukemia (ALL) treated with low anthracycline doses 10 to 20 years earlier. METHODS Seventy-seven ALL survivors who received a cumulative anthracycline dose <250 mg/m² and were at least 10 years after treatment were evaluated for signs of clinical heart failure. Cardiac function was assessed by echocardiography including tissue Doppler measurements of the septal mitral annulus in 37 ALL survivors 10.6-18.3 years (median 13.3 years) after anthracycline treatment with cumulative doses of 180 (n = 19) or 240 mg/m² (n = 18). The control group consisted of 30 healthy volunteers matched for age, sex, BSA, and BMI. RESULTS No clinical relevant cardiotoxicity was found. Left ventricular shortening fraction (SF) was significantly reduced in male ALL survivors. Three of the 19 male ALL survivors had an SF below 30%. Male ALL survivors showed a significantly lower early filling velocity to atrial contraction velocity ratio but myocardial velocity during early filling was comparable between patients and controls. ALL survivors had a significantly longer isovolumetric relaxation time (IVRT). Thirty percent of the ALL survivors have an abnormal IVRT compared to the normal range of the controls. CONCLUSION AND IMPLICATIONS FOR CANCER SURVIVORS At a median of 13.3 years after exposure to cumulative doses of anthracyclines of 180 or 240 mg/m², no clinical relevant cardiotoxicity was found but subclinical cardiac abnormalities were present in 30% of the patients.

Abstract
The purpose of this study was to define the role of tissue and flow myocardial performance index (MPI) measured during dobutamine stress and tissue Doppler echocardiography in the early diagnosis of late cardiotoxicity among patients with childhood cancer treated with anthracycline. The study included 20 patients (14 male and 6 female; mean age 18.4 +/- 3.2 years) as the study group and 18 healthy volunteers (14 female and 4 male, mean age: 19.2 +/- 4.0) as the control group. The mean cumulative dose of anthracycline treatment was 282.1 +/- 125.9 mg/m2, and the mean time period after the last dose of anthracycline was 10.2 +/- 4.0 years. Echocardiography was performed during rest and at infusions of 5, 10, 15, and 20 micro/kg/min dobutamine. Although only isovolumetric relaxation and contraction times of the patient group were prolonged at rest, dobutamine infusion showed significant differences in % left ventricle (LV) posterior wall thickening, LV end-systolic wall stress, LV diastolic and systolic diameter, mitral acceleration, and deceleration time in the patient group compared with the control group. Tissue and flow MPI of the LV, tissue MPI of the right ventricle (RV), and interventricular septum of the patient group were higher than the control group throughout the test. LV tissue MPI increased much more than LV flow MPI when stress was increased. In conclusion, LV tissue MPI value during stress is more valuable than LV flow MPI in the early diagnosis of late cardiotoxicity. RV function can be assessed by tissue Doppler MPI.

Abstract
BACKGROUND The use of anthracycline chemotherapy is limited by the occurrence of cardiotoxicity. To prevent this cardiotoxicity, different anthracycline dosage schedules have been studied. OBJECTIVES To determine the occurrence of cardiotoxicity with the use of different anthracycline dosage schedules (i.e. peak doses and infusion durations) in cancer patients. SEARCH STRATEGY We searched the databases of The Cochrane Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 4, 2008), MEDLINE (1966 to November 2008) and EMBASE (1980 to November 2008). Also, we searched reference lists of relevant articles, conference proceedings and ongoing trials databases. SELECTION CRITERIA Randomised controlled trials (RCTs) in which different anthracycline dosage schedules were compared in cancer patients (children and adults). DATA COLLECTION AND ANALYSIS Two authors independently performed the study selection, the risk of bias assessment and the data-extraction. MAIN RESULTS We identified seven RCTs addressing different anthracycline infusion durations. The meta-analysis showed a statistically significant lower rate of clinical heart failure with an infusion duration of 6 hours or longer as compared to a shorter infusion duration (relative risk (RR) = 0.27; 95% confidence interval (CI) 0.09 to 0.81; 5 studies; 557 patients). The majority of patients included in these studies were adults with different solid tumours. For different anthracycline peak doses we identified two RCTs addressing a doxorubicin peak dose of less than 60 mg/m(2) versus 60 mg/m(2) or more, one RCT addressing a liposomal doxorubicin peak dose of 25 mg/m(2) versus 50 mg/m(2) and one RCT addressing an epirubicin peak dose of 83 mg/m(2) versus 110 mg/m(2). In none of the studies a significant difference in the occurrence of clinical heart failure was identified. All patients included in these studies were adults with different solid tumours. AUTHORS' CONCLUSIONS An anthracycline infusion duration of six hours or longer reduces the risk of clinical heart failure and it seems to reduce the risk of subclinical cardiac damage. Since there is only a small amount of data for children and data obtained in adults cannot be extrapolated to children, different anthracycline infusion durations should be evaluated further in children.No significant difference in the occurrence of clinical heart failure was identified in patients treated with a doxorubicin peak dose of less than 60 mg/m(2) or 60 mg/m(2) or more. For the other identified peak doses only one RCT was available, so no definitive conclusions can be made about the occurrence of cardiotoxicity. More high quality research is needed, both in children and adults and in leukaemias and solid tumours.

Abstract
PURPOSE OF REVIEW Echocardiography in pediatric and congenital heart disease is a key diagnostic technique in patients with congenital heart disease. Due to new technological developments, it has become a rapidly evolving field. RECENT FINDINGS In this review, we focus on recent developments in standardization and validation of standard techniques in pediatric and congenital echocardiography. This is mainly related to standardization of image acquisition and normalization of measurements for body size. The rest of the review is focused on the application of three-dimensional echocardiography, tissue Doppler imaging and Speqle tracking techniques to pediatric heart disease. SUMMARY New developments in standardization of echocardiography, the introduction of three-dimensional echocardiography and new functional techniques such as tissue Doppler and Speqle tracking strengthen the position of pediatric echocardiography as the most important diagnostic tool for patients with congenital heart disease.
