“…Direct flow regions could be obtained by tracking particles forward and backward in time, tagging particles that pass through the aortic or mitral valve during the same beat, and mapping them back to their starting locations, as done previously [4, 6]. However, one advantage of the approach presented here is that LCS depict the time-dependent flow topology, in addition to providing a means to quantify these measures.…”

Topology of Blood Transport in the Human Left Ventricle by Novel Processing of Doppler Echocardiography

et al. 2013

Novel processing of Doppler-echocardiography data was used to study blood transport in the left ventricle (LV) of 6 patients with dilated cardiomyopathy and 6 healthy volunteers. Bi-directional velocity field maps in the apical long axis of the LV were reconstructed from color-Doppler echocardiography. Resulting velocity field data were used to perform trajectory-based computation of Lagrangian coherent structures (LCS). LCS were shown to reveal the boundaries of blood injected and ejected from the heart over multiple beats. This enabled qualitative and quantitive assessments of blood transport patterns and residence times in the LV. Quantitative assessments of stasis in the LV are reported, as well as characterization of LV vortex formations from E-wave and A-wave filling.

“…An alternative method to approach the tumor was the right or left thoracotomy, which was recorded in 15 cases. 4,31,[37][38][39][40][41][42][43] In addition, the tumor resection was performed without cardiopulmonary bypass in four cases. 4,9,44,45 In most cases, the tumor was firmly adherent to the adjacent tissues; therefore, a portion of the affected structures had to be excised (the reported structures including left and right atrial wall, interatrial septum, pulmonary artery/vein, right ventricular wall, aortic sinus, aortic valve leaflets, and superior vena cava), and the defects were repaired by patches of pericardium (autologous or bovine), Dacron or polytetrafluoroethylene.…”

“…The diagnosis of these tumors can be established by measuring catecholamines and metanephrines in plasma or 24-hour urine along with imaging techniques such as computed tomography (CT), magnetic resonance imaging, iodine-123-marked metaiodobenzylguanidine (MIBG) scan and positron emission tomography (PET) scan [5]. …”

About 2% of all paragangliomas are located in the chest, and a few have been described to be found in the heart. Primary cardiac paragangliomas are extremely uncommon tumors and surgical experience with this neoplasm is limited. Treatment strategies described in the literature have included simple excision, excision with reconstruction, autotransplantation after excision of the tumor and even orthotopic cardiac transplantation, depending on the extent of disease. A primary retrocardiac paraganglioma catecholamine-productive was identified in an asymptomatic 49–year old female associated to familial pheochromocytoma-paraganglioma syndrome caused by germline mutation of the gen which codifies for the subunit B of succinate dehydrogenase enzyme (SDHB). The neoplasm was surgically excised from the posterior surface of the left atrium via median sternotomy using cardiopulmonary bypass. Direct ligation of feeding vessels of the tumor along with left atrial reinforcement using a pericardial patch was performed. The post-operative course was uneventful, with normalization of catecholamine secretion and no recurrence at three-month follow-up. We review the current literature about this exceptional cardiac tumor, pathophysiological conditions and options for surgical management.
