Project description:BackgroundAtrial myxomas are the most common benign cardiac tumours. Clinical manifestations vary from constitutional symptoms, to valvular stenosis and embolic events, and surgical removal is the only suggested treatment.Case summaryA 50-year-old female patient was referred to our centre for surgical excision of a reported right atrial mass. A transoesophageal echocardiographic exam revealed two right atrial masses and the surgical plan was total removal of both masses. However, during the operation the surgeons were not able to locate the larger of the two masses and embolization to the pulmonary trunk was considered as the most likely explanation in this setting. A control suction of the right ventricle and the proximal part of the pulmonary arteries was performed to check if the mass had embolized distally but this did not yield any mass. The patient was transferred to the intensive care unit and remained stable for 2 h, until she developed an abrupt cardiogenic shock with signs of right heart failure. An emergent pulmonary computed tomography angiography demonstrated the embolized mass to the left pulmonary artery and the patient was retransferred to the operating room for emergent surgical removal of the mass. The patient showed immediate clinical and haemodynamic improvement after the removal of this mass and had an uneventful further hospitalization.DiscussionMultiple right atrial myxomas are rarely reported and surgical excision requires experience, as in case of embolization immediate removal must be obtained to prevent from right ventricle distress and cardiogenic shock.

Project description:Introduction:Myxomas are the most common type of cardiac benign tumors and most of them are located in the left atrium, followed by the right atrium. The majority of Myxomas is located in the left atrium and has a variable clinical presentation. Myxomas affect patients within a wide age range (15-80 years), and the average age is approximately 50 years. There is a female predominance in the sporadic form. Myxomas are usually pedunculated, solitary, and sporadic but may be associated with familial autosomal dominant syndromes. Case presentation:We report a 38-year-old female presented with large myxoma in the right atrium and atypical presentation and successfully underwent surgical excision of right atrial myxoma. The patient was asymptomatic on 6 months follow up. Conclusion:Cardiac myxomas are the most frequent finding among primary cardiac tumors. Clinical manifestations depend on the involvement in valvular obstruction, distant arterial embolisms, or nonspecific, constitutional symptoms. Transoesophageal Echocardiography is the cornerstone for diagnosis of atrial myxoma. Cardiac myxomas should be managed with surgical resection.

Project description:BackgroundMyxoma 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 presentationA 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.ConclusionsRight-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.

Project description:Background:Cardiac myxomas are the most common benign primary tumour of the heart. Clinical presentation is variable and ranges from constitutional symptoms to clinical features due to intracardiac obstruction, such as mitral stenosis, coronary embolization, or systemic embolization. Surgical resection is the only effective treatment to prevent its debilitating and catastrophic complication. Case summary:A 61-year-old woman presented with an-hour history of bilateral leg pain, numbness, lightheadedness, dyspnoea, and diaphoresis. Physical exam was remarkable for pale and cold lower extremities. Arterial pulse was not palpable in the right femoral, popliteal, and posterior tibial and dorsalis pedis arteries bilaterally. Electrocardiogram demonstrated normal sinus rhythm with T-wave inversion in lead I, V2, V3, and V4. Laboratory investigations were remarkable for leucocytosis and elevated troponin. Computed tomography angiogram showed emboli with acute infarcts involving the spleen and kidneys, acute embolic occlusion of right external and internal iliac arteries, and left distal common femoral artery. She underwent emergent bilateral cut-down and femoral artery thrombectomies. Transthoracic echocardiogram demonstrated wall motion abnormalities. Computed tomography angiography of the chest revealed an atrial mass and transoesophageal echocardiography was obtained which confirmed an atrial myxoma. Coronary angiography demonstrated no significant coronary artery disease, raising the possibility of myxoma embolization to the coronary arteries as the cause of her troponin elevation and wall motion abnormality. Subsequently she underwent successful resection of the atrial myxoma. Discussion:The majority of cardiac myxomas are sporadic and arise from the left atrium as an isolated lesion in middle-aged women. Echocardiography is the diagnostic procedure of choice. The long-term survival after surgical resection is excellent and recurrence is rare.

Project description:Diffuse thickening, a layered appearance of the gallbladder wall and the accumulation of surrounding fluid are considered as sensitive and relatively specific imaging findings of gallbladder inflammation. In the absence of gallstones, the diagnosis of acalculous cholecystitis can be further supported by the presence of fever, epigastric pain, right upper abdominal quadrant (RUQ) tenderness on inspiration and elevated markers of inflammation. In this report, we describe a 35-year-old schoolteacher who presented with all of the above clinical, laboratory and imaging findings that were eventually attributed to gallbladder oedema and liver congestion (abdominal imaging and RUQ tenderness) caused by an atrial myxoma interfering, with the atrioventricular circulation of the right heart and causing constitutional manifestations (fever and elevated markers of inflammation).

Project description:Introduction. Dyspnea during pregnancy and in the immediate postpartum or postoperative period is a relatively common symptom that can be an early sign of a life threatening condition. The differential diagnosis is broad and can represent a wide variety of underlying etiologies. Cardiac tumors are one of the rarest causes of dyspnea in a reproductive age women during the postpartum period. Case Presentation. 42-years old G(7)P(1051) presented with acute dyspnea postoperatively after an elected uncomplicated repeat cesarean section and tubal ligation. The patient was diagnosed with a large left atrial cardiac myxoma and required urgent cardiothoracic surgery. Conclusion. The following case illustrates how a standard response to a common postpartum symptom, dyspnea, can divert and distract from less common exam findings. A careful, stepwise evaluation of symptoms and related findings will usually determine the underlying cause so that appropriate and timely treatment can be initiated.

Project description:BackgroundRight atrial thrombus (RAT) may be managed according to morphology and aetiology, i.e. Type A thrombi ('clot-in-transit', hypermobile) are managed with thrombolytics and surgical embolectomy due to high risk of embolization; Type B thrombi (broad-based, globular) may be managed medically as they will very likely maintain a benign course. Experience with management of a Type C thrombus (hypermobile but also broad-based) has not been explicitly described in the literature.Case summaryA 25-year-old man with history of leukaemia with prior right subclavian vein chemoport is found to have massive RAT. Multimodal imaging shows a hypermobile mass attached to the right atrial lateral wall inferior to superior vena cava and prolapsing into right ventricle in diastole. Given the thrombus morphology and likely propagation from subclavian port, risk of catastrophic embolization was deemed high and as such, intervention was indicated. Systemic anticoagulation was considered but deferred due to theoretical risk of dissolving the thrombus stalk leading to embolization. Surgical thrombectomy was offered but the patient declined. Due to evidence for success in RAT, the AngioVac System: Generation 3 (Angiodynamics, Inc., Latham, NY, USA) was chosen for intervention. The RAT was successfully removed without any complication.DiscussionAngioVac suction thrombectomy is a safe alternative option for removal of a Type C, massive, hypermobile RAT.

Project description:BackgroundMyxoma is a common type of primary cardiac tumor. However, there are few researches to illustrate challenge of safely inducing anesthesia in a patient with a giant right atrial myxoma at moderate altitude.Patient concerns and diagnosesA 54-year-old female patient lived in a city with an average altitude of 1932 m with scheduled surgical treatment for giant right atrial myxoma, prompting discussions on appropriate anesthesia modalities given her prolonged residence at moderate altitude.Methods and resultsConsidering the potential impact of moderate altitude on perioperative management, this study emphasizes the necessity of adequate volume preload therapy and the utility of transthoracic echocardiography or transesophageal echocardiography to prevent hemodynamic compromise. Furthermore, it highlights the unique consideration that, post-tumor removal, hypotension may not necessarily lead to decreased oxygen saturation in these patients.ConclusionThis case underscores the importance of avoiding hypotension, as pre-tumor resection blood pressure maintenance primarily determines blood oxygen concentration. Additionally, it sheds light on the intriguing observation that post-tumor removal hypotension may not result in decreased oxygen saturation. These findings have significant implications for the perioperative care of patients with giant right atrial myxoma at moderate altitudes.

Project description:Left atrial myxomas are the most common type of benign primary cardiac tumor. Patients can present with generalized symptoms, such as fatigue, symptoms from obstruction of the myxoma, or even embolization of the myxoma causing distal thrombosis. We describe a case with several-month duration of syncopal episodes that occurred after coughing and with exertion. Computed tomography of the chest showed a 6.1 cm by 4.5 cm mass in the left atrium, later evaluated with an echocardiogram. Cardiothoracic surgery removed the mass, and it was determined to be an atrial myxoma. It is important for an internist to be able to diagnose an atrial myxoma because of the risks associated with embolization and even sudden death as myxoma can block blood supply from atrium to ventricle.

Project description:A 62-year-old man presented to the cardiology clinic with symptoms of fatigue, shortness of breath and swelling in the abdomen and legs. A pedunculated mobile mass with a short stalk in the right atrium was found to originate from the inferior vena caval opening and prolapse into the right ventricle through a tricuspid valve during diastole in echocardiography. The patient was referred to our department and surgery was planned for right atrial myxomas diagnosis. The mass with surrounding tissue was surgically removed using the cardiopulmonary bypass method. No postoperative complications were seen in the currently asymptomatic patient who is still under our follow-up schedule.
