ABSTRACT CONTEXT: Obstruction of the right ventricular outflow tract due to metastatic disease is rare. Clinical recognition of cardiac metastatic tumors is rare and continues to present a diagnostic and therapeutic challenge. CASE REPORT: We present the case of a patient who had severe respiratory insufficiency and whose clinical examinations revealed a giant tumor mass extending from the right ventricle to the pulmonary artery. We discuss the diagnostic and therapeutic options. CONCLUSION: In patients presenting with acute right heart failure, right ventricular masses should be kept in mind. Transthoracic echocardiography appears to be the most easily available, noninvasive, cost-effective and useful technique in making the differential diagnosis.

Abstract Background: Right ventricular (RV) failure induced by sustained pressure overload is a major contributor to morbidity and mortality in several cardiopulmonary disorders. Reliable and reproducible animal models of RV failure are important in order to investigate disease mechanisms and effects of potential therapeutic strategies. To establish a rat model of RV failure perfectly, we observed the right ventricle and carotid artery hemodynamics characteristics in different degrees of pulmonary artery banding of rats of different body weights. Methods: Rats were subjected to 6 groups：control(0%, n=5)(pulmonary arterial banding 0%), PAB(1-30%, n=4)(pulmonary arterial banding1-30%), PAB(31-60%, n=6)(pulmonary arterial banding31-60%),PAB(61-70%, n=5)(pulmonary arterial bandin61-70%), PAB(71-80%,n=4)(pulmonary arterial banding71-80%), PAB(100%, n=3)(pulmonary arterial banding 100%). We measured the right ventricular pressure(RVP) by right heart catheterization when the pulmonary arterial was ligated. Results: The RVP gradually increased with increasing degree of banding, but when occlusion level exceeding 70%, high pressure state can be only maintained for a few minutes or seconds, and then the RVP drops rapidly until it falls below the normal pressure, which in Group F particularly evident.Conclusions: RVP have different reactions when the occlusion level is not the same, and the extent of more than 70% ligation is a successful model of acute right heart failure. These results may have important consequences for therapeutic strategies to prevent acute right heart failure.

Abstract Introduction Myxomas are the most frequent primary cardiac neoplasms. It is currently believed that myxomas are derived from multipotent mesenchymal cells capable of both neural and epithelial differentiation Histologically, these tumors are composed of dispersed cells within a stroma of mucopolysaccharides Myxomas produce vascular endothelial growth factor, which probably contributes to the growth induction at the initial stages of tumor growth. Tumors vary widely in size, ranging from 1 to 15 cm in diameter and weighing between 15 and 180 g. About 35 percent of myxomas are friable, and they tend to present emboli. The clinical characteristics of these tumors are closely related to their location, size, and mobility; there are no specific signs and symptoms that suggest the presence of a myxoma. There are several mechanisms by which cardiac tumors can cause symptoms. The blockage of circulation through the heart or heart valves produces symptoms of heart failure. Atrial myxoma can interfere with the valves of the heart and cause regurgitation. They can also produce systemic embolisms and constitutional signs. Clinical Case We present a 29-year-old female patient who started with fatigue, weight loss, increased abdominal perimeter and dyspnea of one month"s effort that progressed to dyspnea at rest in the last week associated with syncope, so she decided to go to the emergency department of our institution. Upon arrival at the emergency room, the patient was found with vital signs within normal parameters, however with dyspnea at rest, jugular plethora and important lower limb edema. On auscultation, a systolic-diastolic murmur was found with an increase in the Rivero Carvallo maneuver, with reinforcement of the pulmonary component of the second noise and parasternal high-left rise. In clinical analysis, NT-proBNP 5698pg/mL, AST 34, INR 1.65 and serum lactate of 4.2 was found. A Transthoracic Echocardiogram (TTE) was performed, where a 10cm mass effusion was documented that occupied the entire right atrium and protruded into the right ventricular outflow tract. With these findings, medical treatment was started for right heart failure and it was to cardiac surgery for resection of the right atrium where it had been performed, however during the immediate postoperative state, presented biventricular failure and later asystole without achieving a return of spontaneous circulation despite resuscitation maneuvers. Conclusion In this case, it is an unusual presentation of a rare cardiac pathology that started with symptoms of right heart failure due to the obstruction of the right ventricular outflow tract. We consider that it is an interesting clinical case and with important educational aspects to take into consideration the differential clinical diagnoses of a patient presenting to the emergency department with right heart failure.

Aneurysm of sinus of Valsalva is a rare cardiac abnormality. Unruptured aneurysm of sinus of Valsalva is usually asymptomatic and often discovered incidentally. However, a large aneurysm can, in rare cases, cause compression of the ventricular outflow tract. We report a case of 17-year-old male with congestive right heart failure with a large, partially thrombosed unruptured aneurysm of the right sinus of Valsalva. The aneurysmal sac was compressing the right ventricular outflow tract causing marked dilatation of the right ventricle and atrium that was confirmed on contrast-enhanced computed tomography imaging. Unruptured sinus of Valsalva aneurysm causing right heart failure in adolescence has been rarely reported in literature.

Introduction. Myxomas arising from the right ventricle are extremely rare. Case report. We presented a 71-year-old patient with worsening symptoms of the exertional dyspnea and atypical chest pains lasting 6 months. A transthoracic and transesophageal echocardiogram revealed a large, 2.6 x 2.2 cm, ovoid, well-circumscribed, echogenic mass in the right ventricle outflow tract attached by small pedicle, partly obstructing the right ventricular outflow tract and protruding through the pulmonic valve during systole. The tumor was completely removed with the stalk and 5 mm of the surrounding tissue. The histopathological findings confirmed the diagnosis of myxoma. Conclusion. This case illustrates the usefulness of echocardiography both in diagnosis of patients with atypical symptoms without family history and associated syndromes (like Carney?s complex), and in surgical approach planning. It also stresses the importance of surgical excision of tumor as soon as possible following the diagnosis to prevent the complications such are: valvular obstruction, pulmonary embolization and syncopes.

Abstract Background Myxoma is an uncommon disease and its symptoms vary greatly depending on size, location and mobility. Right-sided myxoma, especially right ventricular myxoma, is much rarer, and the symptoms are alien and uncharacteristic. The lack of understandings poses challenges to prompt diagnosis and timely treatment. Case presentation A 44-year-old female patient was diagnosed with giant right ventricular tumor. Right heart failure and systemic congestion caused by right ventricular outflow tract obstruction were observed on this case. Surgery was performed to excise the mass which was measured at 9.5 * 5.0 cm and confirmed as myxoma pathologically. Conclusions Right-side myxoma is easy to be unnoticed due to its low incident rate and atypical symptoms. Delay in surgical intervention might cause unrecoverable complications. More comprehensive understanding of the symptoms is expected to help improving the diagnose and treat of right-sided myxoma.

Rv Function

IntroductionPulmonary artery pressure (PAP) is increased and right ventricular (RV) function is well preserved in healthy subjects upon exposure to high altitude (HA). An increase in PAP may trigger notching of the right ventricular outflow tract Doppler flow velocity envelope (RVOT notch), which is associated with impaired RV function in patients with pulmonary hypertension. However, whether HA exposure can induce RVOT notch formation and the subsequent impact on cardiac function in healthy subjects remains unclear.MethodsA total of 99 subjects (69 males and 30 females) with a median age of 25 years were enrolled in this study; they traveled from 500 to 4100 m by bus over a 2-day period. All subjects underwent a comprehensive physiological and echocardiographic examination 1 day before ascension at low altitude and 15 ± 3 h after arrival at HA. The RVOT notch was determined by the presence of a notched shape in the RVOT Doppler flow velocity envelope. The systolic PAP (SPAP) was calculated as Bernoulli equation SPAP = 4 × (maximum tricuspid regurgitation velocity)2+5 and mean PAP (mPAP) = 0.61 × SPAP+2. Cardiac output was calculated as stroke volume × heart rate. Pulmonary capillary wedge pressure (PCWP) was calculated as 1.9+1.24 × mitral E/e’. Pulmonary vascular resistance (PVR) was calculated as (mPAP-PCWP)/CO.ResultsAfter HA exposure, 20 (20.2%) subjects had an RVOT notch [notch (+)], and 79 (79.8%) subjects did not have an RVOT notch [notch (−)]. In the multivariate logistic regression analysis, the SPAP, right ventricular global longitude strain (RV GLS), and tricuspid E/A were independently associated with the RVOT notch. The SPAP, mPAP, PVR, standard deviations of the times to peak systolic strain in the four mid-basal RV segments (RVSD4), peak velocity of the isovolumic contraction period (ICV), and the peak systolic velocity (s’) at the mitral/tricuspid annulus were increased in all subjects. Conversely, the pulse oxygen saturation (SpO2), RV GLS, and tricuspid annulus plane systolic excursion (TAPSE)/SPAP were decreased. However, the increases of SPAP, mPAP, PVR, and RVSD4 and the decreases of SpO2, RV GLS, and TAPSE/SPAP were more pronounced in the notch (+) group than in the notch (−) group. Additionally, increased tricuspid ICV and mitral/tricuspid s’ were found only in the notch (−) group.ConclusionHA exposure-induced RVOT notch formation is associated with impaired RV function, including no increase in the tricuspid ICV or s’, reduction of RV deformation, deterioration in RV-pulmonary artery coupling, and RV intraventricular synchrony.
