Large Pericardial Effusion

Abstract Background and aim Coronary sinus (CS) as an intrapericardial, low-pressure, thin-walled structure can be easily compressed in cardiac tamponade. Whereas, inferior vena cava (IVC) is an extrapericardial structure which dilates in tamponade as opposed to the response of CS. The inverse relationship between these two venous structures may augment their role in the evaluation of tamponade imaging. Therefore, we assessed the usefullness of computerized tomographic measures of CS diameter, and also CS to IVC ratio (CS/IVC) to predict tamponade in clinically stable patients with large pericardial effusion. Materials and methods 66 clinically stable patients who had large pericardial effusions, were included to the study. CS diameter was measured from the point at 1 cm proximal to the CS ostium11. IVC diameter was measured from the segment between its right atrial orifice and hepatic vein. Results Patients with tamponade had 40% smaller CS diameter (5.3±1.8 vs 8.8±2.6 mm p<0.001) and 35% lower CS/IVC ratio (20.7±5.5 vs 34.7±10.5% p<0.001).After adjusting with other parameters, only either CS diameter or CS/IVC ratio predicted tamponade respectively. (Nagelkerke r square value for CS diameter was 53.7% and 72.1% for CS/IVC ratio). 1 mm increase in CS diameter and 1% increase in CS/IVC ratio were associated with an increased odds ratio of 59% and 39% in predicting tamponade, respectively (p value <0.001).In ROC analysis, a cut of value of 6.85 mm for CS diameter, had 82.6% sensitivity and 83.7% specificity for predicting cardiac tamponade (Area under the curve 0.879, p<0.001). Additionally, a cut of value of 27% for CS / IVC ratio had 87.0% sensitivity and 86.0% specificity for predicting cardiac tamponade (Area under the curve 0.945, p<0.001). Conclusion The tomographic measures of both the CS diameter and the CS/IVC ratio predicted tamponade in clinically stable patients with large pericardial effusion. Compared with CS diameter, CS/IVC ratio seemed to be a more powerful predictor of tamponade Figure 1 Funding Acknowledgement Type of funding source: None

Abstract This paper outlines a case study 57 year old, female patient who was admitted in our institution due to severe sign and symptoms of right-sided heart failure. She complained on progressive fatigue, a shortness of breath and oedema of cruris for three months before. Initially she was hospitalized in regional hospital due to pericardial effusion and they excluded any malignancy and systemic tissue disease in that moment. Immediately after admission we have performed 2D transthoracic echocardiography which showed a large (6.7x4.9cm), oval tumours soft tissue formation in right atrium which compromise flow in Vena cava inferior and across tricuspid valve and make a gradient of 35 mmHg above it. Left and right ventricles had preserved dimensions and function, without pericardial effusion. 3D transoesophageal echocardiography (TEE) imaged confirmed huge, oval tumorous formation (8.2x7.9cm), which originated from lateral wall of right atrium and almost occupied it, compromising flow towards superior and inferior vena cava. We had detected an irregular free space, probably due to necrosis, in the middle part of that tumorous formation. Thorax MSCT revealed heterogeneous expansive mass (19x8x8 cm) in projection of right atrium with signs of active bleeding its central part, although MSCT couldn’t exclude extra cardiac origin. There were no signs of dissemination. Cardiac MR indicated that we had extra cardiac mass (12x9x10cm) close to lateral right atrial wall and basal part of lateral wall of right ventricle which compromise flow towards superior and inferior vena cava, with no changes on surrounding structures. The patient underwent almost complete tumour surgical resection, with a lot of bleeding complications due to its local invasiveness and central necrosis. Surgical findings completely were concordant with 3D TEE imagining which provided us very precise information about size, location and extension of tumour. Severe systemic inflammatory response syndrome (SIRS) occurred in the postoperative period, and the patient died due to multiple organ dysfunction. Patohistological analyses were conclusive of undifferentiated pleomorphic sarcoma diagnosis. Abstract P172 Figure.

Abstract Background Inferior vena cava (IVC) obstruction is a rare complication of orthotopic heart transplantation (OHT) and is unique to bicaval surgical technique. The clinical significance, diagnosis, complications, and management of post-operative IVC anastomotic obstruction have not been adequately described. Case summary Two patients with end-stage heart failure presented for bicaval OHT. Post-operative course was complicated with shock refractory to fluid resuscitation and inotropic/vasopressor support. Obstruction at the IVC-right atrial (RA) anastomosis was diagnosed on transoesophageal echocardiography (TOE), prompting emergent reoperation. In both cases, a large donor Eustachian valve was found to be restricting flow across the IVC-RA anastomosis. Resection of the valve resulted in relief of obstruction across the anastomosis and subsequent improvement in haemodynamics and clinical outcome. Discussion Presumably rare, we present two cases of IVC obstruction post-bicaval OHT. Inferior vena cava obstruction is an under-recognized cause of refractory hypotension and shock in the post-operative setting. Prompt recognition using TOE is crucial for immediate surgical correction and prevention of multi-organ failure. Obstruction can be caused by a thickened Eustachian valve caught in the suture line at the IVC anastomosis, which would require surgical resection.

Inferior vena cava (IVC) diameter and respirophasic variation are commonly used echocardiographic indices to estimate right atrial pressure. While dilatation of the IVC and reduced collapsibility have traditionally been associated with elevated right heart filling pressures, the significance of isolated IVC dilatation in the absence of raised filling pressures remains poorly understood. We present a case of an asymptomatic 28-year-old male incidentally found to have IVC dilatation, reduced inspiratory collapse, and normal right heart pressures.

Hepatocellular carcinoma usually metastasizes to regional lymph nodes, lung, and bones but can rarely invade the inferior vena cava with intravascular extension to the right atrium. We present the case of a 75-year-old man who was admitted for generalized oedema and was found to have advanced HCC with invasion of the inferior vena cava and endovascular extension to the right atrium. In contrast to the great majority of hepatocellular carcinoma, which usually develops on the basis of liver cirrhosis due to identifiable risk factors, none of those factors were present in our patient.

Introduction Heterotaxy syndrome/ isomerism is characterized by an abnormal symmetry of the viscera that are normally dissimilar due to abnormal lateralization of thoracic and abdominal viscera and is frequently associated with complex cardiac anomalies. Isomerism may be of right or left. Materials and methods This article describes the morphological characteristics of heterotaxy and suggests an approach in evaluating the spectrum of abnormalities associated with this syndrome. This study is based on 12 cases diagnosed on antenatal ultrasound as heterotaxy syndrome. Results of the examinations were re-evaluated and compared by fetal autopsy. Result Based on the following echocardiographic criteria, a diagnosis of left isomerism was made if there was viscerocardiac heterotaxy associated with an interruption of inferior vena cava or with bilateral finger-like atrial appendages or if it was associated with heart block. If there was evidence of viscerocardiac heterotaxy with complex cardiac anomalies then it was diagnosed as right atrial isomerism or visceral heterotaxy syndrome. We diagnosed 6/12 as left isomerism and rest of the cases as right isomerism/visceral heterotaxy syndrome. In Autopsy we evaluated visceral situs and morphology of the lungs and the main bronchi, the state of the liver, spleen, bowel, and the precise anatomy of the heart and confirmed 4/12 as left isomerism 4/12 as right isomerism and two cases as visceral heterotaxy syndrome (VHS). Rest of the two cases were included in the study despite missing autopsy data, as the combination of abnormal situs with interrupted inferior vena cava, and cardiac malformation allowed a diagnosis of left isomerism with high probability. Conclusion In this study, we aimed to find common features of heterotaxy syndrome on prenatal ultrasound as well as on fetal autopsy. This syndrome should be accurately diagnosed in the prenatal period in order to allow appropriate counseling of parents.

Objective: Malposition of dual lumen cannula is a frequent and challenging complication in neonates and plays a significant role in shaping the in vitro device hemodynamics. This study aims to analyze the effect of the dual lumen cannula malposition on right-atrial hemodynamics in neonatal patients using an experimentally validated computational fluid dynamics model. Methods: A computer model was developed for clinically approved dual lumen cannula (13Fr Origen Biomedical, Austin, Texas, USA) oriented inside the atrium of a 3-kg neonate with normal venous return. Atrial hemodynamics and dual lumen cannula malposition were systematically simulated for two rotations (antero-atrial and atrio-septal) and four translations (two intravascular movements along inferior vena cava and two dislodged configurations in the atrium). A multi-domain compartmentalized mesh was prepared to allow the site-specific evaluation of important hemodynamic parameters. Transport of each blood stream, blood damage levels, and recirculation times are quantified and compared to dual lumen cannula in proper position. Results: High recirculation levels (39 ± 4%) in malpositioned cases resulted in poor oxygen saturation where maximum recirculation of up to 42% was observed. Apparently, Origen dual lumen cannula showed poor inferior vena cava blood–capturing efficiency (48 ± 8%) but high superior vena cava blood–capturing efficiency (86 ± 10%). Dual lumen cannula malposition resulted in corresponding changes in residence time (1.7 ± 0.5 seconds through the tricuspid). No significant differences in blood damage were observed among the simulated cases compared to normal orientation. Compared to the correct dual lumen cannula position, both rotational and translational displacements of the dual lumen cannula resulted in significant hemodynamic differences. Conclusion: Rotational or translational movement of dual lumen cannula is the determining factor for atrial hemodynamics, venous capturing efficiency, blood residence time, and oxygenated blood delivery. Results obtained through computational fluid dynamics methodology can provide valuable foresight in assessing the performance of the dual lumen cannula in patient-specific configurations.
