Myocardial perfusion contrast echocardiography is an imaging tool for the assessment of myocardial microcirculation. It can also be used for the evaluation of the relative perfusion of a cardiac mass. Cardiac hemangiomas are rare tumors, accounting for only 2.8% of all benign primary cardiac tumors. We report a case of a 17-year-old man with a left ventricular hemangioma detected with transthoracic echocardiography. Myocardial perfusion contrast echocardiography was used to evaluate the vascularity of the cardiac mass. Using this technique malignant and hypervascular (<em>e.g</em>., hemangioma) tumors display persistence of contrast enhancement compared to the surrounding myocardium. The mass was successfully removed and the final report from pathology showed that the left ventricular mass was a hemangioma, a hypervascular tumor

Primary Cardiac Tumors

AbstractAmongst all primary cardiac tumors, myxomas are the commonest, and their commonest site of origin is the left atrium. Myxomas originating in the left ventricle are rare. When seen, they usually present with a history of systemic embolisation and/or syncopal episodes, with constitutional symptoms being absent. We report here a child with left ventricular myxoma who presented with a prolonged febrile illness.

Atrial Myxoma is the most common primary cardiac tumors accounting for about 50% of benign primary cardiac tumors, with the majority located in the left atrium. This is a case of large left atrial (LA) myxoma presented with features of mitral stenosis associated with moderate left ventricular failure (LVF) and mild pulmonary artery hypertension (PAH) The patient improved markedly after tumor excision.Pulse Vol.10 January-December 2017 p.29-33

AbstractPrimary cardiac tumors are rare in infancy and childhood. We describe the features of large intramural ventricular cardiac fibromas discovered in two children. In the first, a left ventricular apical tumor was discovered by means of echocardiography and left ventriculography in a symptomless 8-year-old boy. The intramural fibroma was successfully resected. In the other case, an 8-month-old female infant with severe congestive heart failure, sudden ventricular tachycardia and fibrillation occurred during left ventriculography. At necropsy a tumor was seen bulging in the anterior wall of the left ventricle and in the ventricular septum. Histology showed the tumor to be a fibroma.

Abstract Funding Acknowledgements Type of funding sources: None. Background The noninvasive assessment of myocardial perfusion by echo contrast agents in patients with acute myocardial infarction with ST-segment elevation (STEMI) after successful revascularization is becoming a relevant clinical reality. Perfusion imaging techniques with myocardial contrast echocardiography (MCE) remains the least studied and most promising ultrasound technology for the diagnosis of no-reflow phenomenon. Purpose To study the echocardiographic and angiographic characteristics of the no-reflow phenomenon detected by MCE in patients with STEMI. Methods The study included 43 patients aged from 40 to 82 years in acute stage of myocardial infarction. Patients were divided into two groups: 32 patients characterized by sufficient myocardial reperfusion after revascularization according to MCE results and 11 patients were with the impaired perfusion. Results The patients with impaired perfusion demonstrated a greater size of the left ventricular (LV) asynergy (40.1 ± 2.2% vs 27.4 ± 8.5%, p &lt; 0.001). LV dilatation (LV end-systolic volume 67.3 ± 20.3 ml vs 51.8 ± 17.2 ml, p = 0.015), impaired LV ejection fraction (39.5 ± 3.4% vs 47.2 ± 4.9%, p &lt; 0.001), and significant mitral regurgitation (45.5% vs 3.1%, p = 0.011) with a decrease in DP/DT (979.9 ± 363.4 mmHg/s vs 1565.7 ± 502.8 mmHg/s, p &lt; 0.001) was more often detected in this group. In more than a quarter of these patients, coronary angiography showed no perfusion disorders after revascularization. In the group with impaired perfusion by MCE, the single-vascular lesions (46.9% vs 9.1%, p = 0.033), the lesions of the anterior interventricular artery (90.9% vs 40.6%, p = 0.004), and acute occlusion (100% vs 68.8%, p = 0.043) were more often determined. Conclusion According to the results of MCE, the echo signs of LV dysfunction were more pronounced after successful revascularization in patients with STEMI and myocardial perfusion disorders. The SYNTAX score was twice higher in these patients compared to the patients with recovered perfusion. In addition, no-reflow phenomenon by MCE was observed in the most patients with anterior interventricular artery lesion.

SummaryA papillary fibroelastoma is a rare, avascular, cardiac tumour that is often found incidentally using transthoracic echocardiography (TTE). Peripheral i.v. injection of a microbubble contrast agent is often used to characterize abnormal masses within the heart allowing further delineation of physical features, the area of attachment, and vascularity of the mass in order to differentiate the growth from a tumour or a thrombus. This case highlights a potential pitfall when assessing a cardiac tumour's vascularity using contrast TTE. A cardiac mass was identified on a TTE of a 53-year-old man and was further investigated with microbubble contrast-enhanced TTE. Contrast TTE imaging suggested a vascularized structure in the left ventricle. However, after histological examination the tumour was found to be entirely avascular.Learning pointsDifferentiation of cardiac tumour is usually best performed with contrast echocardiography.Contrast echocardiography may not be best tool to determine if cardiac mass is vascularized.A papillary fibroelastoma can appear vascularized with contrast echocardiography due to it's frond-like structures.Physicians should be aware of this potential confusion when assessing a cardiac tumour in patients.

Before And After

Genetically altered mice are useful to understand cardiac physiology. Myocardial contrast echocardiography (MCE) assesses myocardial perfusion in humans. We hypothesized it could evaluate murine myocardial perfusion before and after acute coronary ligation. MCE was performed before and after this experimental myocardial infarction (MI) in anesthetized mice by intravenous injection of contrast microbubbles and transthoracic echo imaging. Time-video intensity curves were obtained for the anterior, lateral, and septal myocardial walls. After MI, MCE defects were compared with the area of no perfusion measured by Evans blue staining. In healthy animals, intramyocardial contrast was visualized in all the cardiac walls. The anterior wall had a higher baseline video intensity (53 ± 17 arbitrary units) than the lateral (34 ± 13) and septal (27 ± 13) walls ( P < 0.001) and a lower increase in video intensity after contrast injection [50 ± 17 vs. 60 ± 24 (lateral) and 65 ± 29 (septum), P < 0.01]. After MI, left ventricular (LV) dimensions were enlarged, and the shortening fraction was decreased. A perfusion defect was imaged with MCE in every mouse, with a correlation between MCE perfusion defect size (35 ± 13%) and the nonperfused area by Evans blue (37 ± 16%, y = 0.77 x + 6.1, r = 0.93, P < 0.001). Transthoracic MCE is feasible in the mouse and can accurately detect coronary occlusions and quantitate nonperfused myocardium.
