Cardiac rhabdomyomas (CRs) are the most common heart tumors in children and closely associated with tuberous sclerosis complex (TSC). This study was performed to assess the presentation type, clinical course, treatment modalities, and outcome of the patients with rhabdomyoma, associated with TSC. We reviewed our patients with cardiac rhabdomyomas (CRs), who had received a diagnosis of TSC previously or during the follow-up period between June 1996 and January 2012, retrospectively. Thirty-two patients with TSC were evaluated and among them 11 patients (34%) were associated with CRs. Five patients (45%) had multiple tumors and consequently a total of 29 CRs were analyzed in our study. The median follow-up period was 2 years (range: 1 week-15 years). Clinical presentation was cardiac murmur in three patients, cyanosis in two patients and arrhythmia in one patient. Five patients were asymptomatic at the diagnosis and CRs were detected during routine cardiac evaluation for TSC. Cardiac tumors were diagnosed prenatally in two patients. Spontaneous regression rate was 31% and we experienced a complete regression of a tumor with an echogenic bordered tissue defect and septal thinning in a patient. Three patients had hemodynamically significant tumor obstruction; two of them underwent surgery. The other patient, who had multiple CRs, was treated medically with everolimus because of high-risk potential of surgery. Although surgical resection is the preferred treatment in most of the patients with hemodynamic instability, we need novel alternative medical therapies in some critically ill patients who cannot be operated due to various reasons.

Although T2* MRI is the most sensitive test detecting myocardial iron load, TDI and STE can be used for screening myocardial dysfunction. The abnormal strain values, especially circumferential, may be detected as the first finding of abnormal iron load and related to T2* values.

Increased awareness about the association of certain CHD with persistent left SVC and a careful echocardiographic examination can facilitate the diagnosis of persistent left SVC. In addition, precise prior diagnosis of persistent left SVC can prevent complications during surgery.

The objective was to compare the efficacy and safety of naproxen (NXN) to acetylsalicylic acid (ASA) in the treatment of acute rheumatic fever (ARF). The data of 338 children were retrospectively analyzed. The patients were grouped according to joint and valve involvement and also drug chosen [methyl prednisolone (mPSL), ASA or NXN]. The treatment results and adverse events in each group were compared. The mean age was 10.3 years and the median follow-up was 62 months. Median time for normalization of acute phase reactants was 1 week in patients given steroids and 2 weeks in patients given ASA or NXN. ASA was replaced with NXN in 18 patients (10.2%) due to hepatic toxicity. The rate of rebound, recurrence and the prevalence of rheumatic valve disease were not different in patients given NXN, ASA or mPSL. In conclusion, NXN is a safe and effective alternative to ASA in the treatment of ARF in children.

Echocardiography is the mainstay of screening and disease surveillance in isolated left ventricular non-compaction (iLVNC). The aim of our study is to determine the early regional and global myocardial functional changes and whether the myocardial changes that cannot be detected by conventional echocardiography could be detected by tissue Doppler imaging (TDI) or two-dimensional speckle-tracking echocardiography (STE) in iLVNC cases without symptoms. Longitudinal and circumferential strain (S) and strain rates (SR) as determined by STE in 20 children aged 12.1 ± 3.3 years was compared with those in 20 controls. All children underwent echocardiographic assessment using two-dimensional, tissue Doppler and speckle-tracking echocardiography. iLVNC patients who had normal systolic function by ejection and shortening fractions were included in this study. According to the TDI in all three segments [the non-compacted (NC), neighboring NC (NNC) and compacted (C) segments], isovolumic contraction time, isovolumic relaxation time and myocardial performance index values were significantly higher, while ejection time were significantly lower in the iLVNC group. According to STE in two segments (NC and NNC-segments) longitudinal S and SR values and also circumferential S and SR values were significantly lower in the iLVNC group compared with the control group; whereas, in the global measurements both longitudinal and circumferential S and SR values in all three segments were significantly lower in the iLVNC group compared with the control group. We believe that TDI and STE that evaluates myocardial deformation can be used for the detection of early myocardial dysfunction in the iLVNC patients who are subclinical and whose left ventricular functions were detected as normal by conventional methods with normal ejection and shortening fractions.
