ABSTRACT
Background: Early biventricular dysfunction in repaired tetralogy of Fallot (TOF) children may lead to poor clinical outcomes. We aimed to assess biventricular function in TOF children before and after surgery by speckle tracking echocardiography (STE) and compare them with the controls. Methods: Twenty repaired TOF children and 20 normal children as controls were assessed by STE. Tricuspid annular plane systolic excursion (TAPSE), left ventricular ejection fraction (LVEF), biventricular strain, and strain rate were compared before and after surgery and between TOF children and controls. Results: Postoperative LVEF (p = 0.001), strain (p = 0.001), and strain rate (p = 0.001) for left ventricle improved significantly compared to preoperative phase. However, postoperative left ventricular strain (p = 0.05) and strain rate (p = 0.01) in TOF children were significantly impaired compared to controls. Postoperative LVEF was correlated inversely with postoperative strain rate (r = -0.40, p = 0.04). Postoperative TAPSE (p = 0.001), strain (p = 0.001), and strain rate (p = 0.001) for right ventricle significantly worsened when compared with the preoperative phase. Moreover, postoperative TAPSE (p = 0.001), strain (p = 0.001), and strain rate (p = 0.01) were significantly impaired compared to controls. Postoperative right ventricular strain rate was correlated significantly with the weight of children (r = 0.48, p = 0.02), and postoperative left ventricular strain showed significant correlations with aortic clamp time (r = 0.44, p = 0.04) and with ICU stay (r = -0.46, p = 0.04). Conclusion: Despite normal LVEF, TOF children exhibit impaired left ventricular strain and strain rate after surgery. TAPSE, strain, and strain rate for the right ventricle worsen after surgical repair. STE-driven strain can be used to detect early ventricular dysfunction and the associated prognostic implications.
ABSTRACT
We herein describe a case series of children with SARS-CoV-2 infection (COVID-19) complicated with acute intracardiac thrombosis. The diagnosis of COVID-19 was confirmed through the reverse transcription-polymerase chain reaction (RT-PCR). Transthoracic echocardiography of patients revealed large intracardiac mobile masses resected successfully via cardiac surgery. The underlying mechanisms of this thrombus in the COVID-19 infection may be attributed to the hypercoagulation and inflammatory state of the disease incurred by the SARS-CoV-2 virus.
ABSTRACT
INTRODUCTION: Tinnitus is a common complaint in patients referred to otorhinolaryngology clinics and is a condition where one hears a sound without any distinguishable external acoustic source or electrical stimulus. About 3-30% of adults experience different degrees of tinnitus during their life. This study aims to ascertain and compare personality traits between patients with tinnitus and a control group. MATERIALS AND METHODS: In a case control study, 66 participants were assessed. The case group consisted of 33 patients who suffered from tinnitus for at least two months, in addition to 33 healthy volunteers who were selected among their family (preferably of the same age and sex). A standard demographic questionnaire and an Eyzenck personality questionnaire were filled for both groups. A tinnitus severity index (TSI) questionnaire was only filled for the case group. Data from each group was compared by Mann-Whitney U and Chi-Square tests. SPSS V.18 was the selected software. RESULTS: Statistical analysis showed a meaningful difference in neuroticism (P=0.001) and extraversion (P=0.001) between the patients and the controls; however, there was no statistical difference between these groups regarding psychotism. CONCLUSION: Tinnitus can be associated with personality characteristics. This study showed that in patients with tinnitus, neuroticism increases and extraversion decreases. Considering the personality and psychotic traits observed in the patients with tinnitus, psychiatric consultation is recommended.
