Endocarditis is a recognised complication of both temporary and permanent indwelling right atrial catheters. Endocardial damage by the catheter may result in non-bacterial thrombotic endocarditis. Sterile vegetations composed of platelets and fibrin may become infected, either by direct spread of bacteria along the catheter, or following an episode of bacteraemia. Bacteria in infected vegetations may be protected from phagocytosis by a ‘roof’ of fibrin. Echocardiography is a valuable non-invasive method of diagnosis and may be used to monitor the resolution of vegetations and valve function. The right atrial catheter produces reflections which must be distinguished from cardiac abnormalities. We report a case of infective endocarditis in a patient with severe aplastic anaemia and a permanent indwelling right atrial catheter which was managed conservatively.

Introduction. Myxoma is the most common primary benign heart tumor. The most frequent location is the left atrium, the chamber of the heart that receives oxygen- rich blood from the lungs. Myxomas usually develop in women, typically between the ages of 40 and 60. Symptoms may occur at any time, but most often they are asymptomatic or oligosymptomatic for a long period of time. Symptoms usually go along with body position, and are related to compression of the heart cavities, embolization and the appearance of general symptoms. The diagnosis of benign tumors of the heart is based on anamnesis, clinical features and findings of the tumor masses by use of non-invasive and invasive imaging methods. Extensive surgical resection of the myxoma is curative with minimal mortality. Long term clinical and echocardiographic follow-up is mandatory. Case report. We reported a case of a 62-year-old male, presented with 15 days of intermittent shortness of breath, dizziness and feeling of heart palpitations and subsequently diagnosed with right atrial myxoma based on transthoracic echocardiography . The patient was emergently operated in our hospital. Long-term followup did not reveal recurrence. Conclusion. Our case was an atypical localisation of right atrial myxoma. Whether the intracardiac mass is benign or malignant, early surgery is obligatory in order to prevent complications.

Purpose. The study aimed at the comparison of computed tomography (СT) contrast enhancement (CE) protocols for optimal visualization of cardiac chambers, evaluation of their impact on results of non-invasive superficial cardiac mapping.Methods. The study included 93 patients with heart rhythm disorders in whom catheter ablation of arrhythmia was planned. Noninvasive cardiac mapping for arrhythmia localization was performed and included multichannel ECG-registration and CT with intravenous СE (1st group - monophasic (50 patients), 2nd group - split-bolus (18 patients), 3rd group - with pre-bolus (25 patients). Qualitative and quantitative (measurement of mean blood attenuation in four chambers, calculation of ventricular-myocardial [VM] contrast-to-noise ratio VM-LV и VM-RV for the left ventricle [LV] and right ventricle [RV], respectively) parameters were compared between the groups. Fusion of ECG and CT data was carried out a semi-automatic mode with a non-invasive imaging complex.Results. Regardless of CE technique, sufficient and homogeneous contrast attenuation was obtained for the left atrium (LA) and LV (mean blood attenuation in LA more than 278 HU, LV 250 HU, VM-LV 0,582). In most cases, the enhancement of the right heart was insufficient with the monophasic protocol; the average CT density was lower than 200 HU, VM-RV 0,256. The split-bolus protocol improved visualization of the right atrium (RA) and RV (blood density in RA 258HU, RV 227HU, VMRV 0,541); however, there was a heterogeneity of the RA cavity due to artifacts from the superior vena cava (VC) and unenhanced blood from the inferior VC. Pre-bolus administration increased the contrast ratio between RA myocardium and blood due to the improvement of blood CT density in the inferior VC (blood density 294 HU). The quality of RV CE was similar to 2nd group (blood density 264 HU, VM-RV 0,565).Conclusion. The split-bolus and with pre-bolus CE protocols improve visualization of the RV, supporting the high-level enhancement of the left heart. The protocol with a pre-bolus is preferable for exact differentiation of the right atrial endocardial contour.

Background We evaluated the effect of adenosine upon mechanisms sustaining persistent AF through analysis of contact electrograms and ECGI mapping. Methods Persistent AF patients undergoing catheter ablation were included. ECGI maps and cycle length (CL) measurements were recorded in the left and right atrial appendages and repeated following boluses of 18 mg of intravenous adenosine. Potential drivers (PDs) were defined as focal or rotational activations completing ≥ 1.5 revolutions. Distribution of PDs was assessed using an 18 segment biatrial model. Results 46 patients were enrolled. Mean age was 63.4 ± 9.8 years with 33 (72%) being male. There was no significant difference in the number of PDs recorded at baseline compared to adenosine (42.1 ± 15.2 vs 40.4 ± 13.0; p = 0.417), nor in the number of segments harbouring PDs, (13 (11–14) vs 12 (10–14); p = 0.169). There was a significantly higher percentage of PDs that were focal in the adenosine maps (36.2 ± 15.2 vs 32.2 ± 14.4; p < 0.001). There was a significant shortening of CL in the adenosine maps compared to baseline which was more marked in the right atrium than left atrium (176.7 ± 34.7 vs 149.9 ± 27.7 ms; p < 0.001 and 165.6 ± 31.7 vs 148.3 ± 28.4 ms; p = 0.003). Conclusion Adenosine led to a small but significant shortening of CL which was more marked in the right than left atrium and may relate to shortening of refractory periods rather than an increase in driver burden or distribution.

Effusive Constrictive Pericarditis

When pericardial fluid accumulates and exceed the reserve volume of the pericardium or when the pericardium becomes scarred and inelastic, one of three pericardial compressive syndromes may ensue, namely, cardiac tamponade (CT), characterised by the accumulation of pericardial fluid under pressure; constrictive pericarditis (CP), the result of scarring and loss of the normal elasticity of the pericardial sac; and effusive–constrictive pericarditis (ECP), characterised by the concurrence of a tense pericardial effusion and constriction of the heart by the visceral pericardium. Although relatively uncommon, prevalence estimates vary widely and depend on the nature of the cohorts studied, the methods used to diagnose ECP and the manner in which ECP is defined. Most cases of ECP are idiopathic, reflecting the frequency of idiopathic pericardial disease in general, and other causes include radiation, malignancy, chemotherapy, infection and postsurgical/iatrogenic pericardial disease. The diagnosis of ECP often becomes apparent when pericardiocentesis fails to decrease the right atrial pressure by 50% or to a level below 10 mm Hg. Important non-invasive diagnostic modalities include echocardiography, cardiac magnetic resonance and, to a lesser extent, cardiac CT. In cases with clear evidence of pericardial inflammation, a trial of an anti-inflammatory regimen is warranted. A complete pericardiectomy should be reserved for refractory symptoms or clinical evidence of chronic CP.

Abstract ABSTRACT Treatment and management of infective endocarditis (IE) depends on the side of involvement. Involvement of both sides of heart is rarely encountered. We describe one case of both sided infective endocarditis caused by staphylococcus auerus. In this case, the vegetation is thought to be on the right side of the heart at first examination by transthrorasic echocardiography (TTE). However; when examined more carefully with transoesophageal echocardiography (TEE), nothing was as it seemed. CASE PRESENTATİON A 86-year-old woman, who underwent mechanic aortic valve replacement surgery 11 years before, was admitted to emergency room with fever, dispnea and cough. Physical examination showed a temperature of 38.6. Electrocardiography showed a atrial fibrillation of 112 beats/min. Laboratory tests revealed an elevated C reactive protein of 211 mg/l. The patient was empirically treated with intravenous piperacillin-tazobactam and teicoplanin, by the recommendation of infection disease unit. Staphylococcus aureus grew in both bottles of blood cultures. A TTE showed severe tricuspid regurgitation with vegetation, mild aortic regurgitation and moderate mitral regurgitation with no clear vegetation. We decided perform TEE and realised the vegetation in the right atrium was originated from the right atrial wall not from the tricuspid valve. Then we also noticed a thickening in the walls of aortic root with systolic expansion. This finding was consistent with paraaortic abscess formation. The 3D TEE examination helped us to understand the origin of the vegetation in the right atrium. Because the wall of the right atrium which the vegetation arised from was in direct continuity with the infected aortic root. We conclude that the paraortic abscess was spread to the right atrium by neighborhood. After one week of IV antibiotics treatment, the patient undergone open heart surgery. The surgical inspection confirmed the echocardiographic diagnosis. DISCUSSION Echocardiography helps us in diagnosis, determination of side of involvement, and complications of infective endocarditis. Usually the endocarditis invole only one side of the heart: left or right. We have found only four cases of double-sided endocarditis in literature. Our case is the first one , in which we describe a direct extension of aortic root abscess to the right atrium. Abstract P1474 figure 1

Hemangioma is one of the most common benign liver tumors. They are mostly asymptomatic. Differentiating hemangiomas from malignant tumoral lesions and metastases by a non invasive method is very important. We report a asymptomatic case with incidental finding of a large massive hemangioma occupying almost whole of the right lobe of liver and emphasized its detection by Tc-99m red blood cell (RBC) three phase imaging and localization of the tumor.Bangladesh J.

Language Laterality

The involvement of the right and left hemispheres in mediating language functions has been measured in a variety of ways over the centuries since the relative dominance of the left hemisphere was first known. Functional magnetic resonance imaging (fMRI) presents a useful non-invasive method of assessing lateralisation that is being increasingly used in clinical practice and research. However, the methods used in the fMRI laterality literature currently are highly variable, making systematic comparisons across studies difficult. Here we consider the different methods of quantifying and classifying laterality that have been used in fMRI studies since 2000, with the aim of determining which give the most robust and reliable measurement. Recommendations are made with a view to informing future research to increase standardisation in fMRI laterality protocols. In particular, the findings reinforce the importance of threshold-independent methods for calculating laterality indices, and the benefits of assessing heterogeneity of language laterality across multiple regions of interest and tasks.
