A Voluminous Right Atrial Myxoma Revealed by Right Side Heart Failure

Mini‐AbstractRight atrial myxoma is rare. Its clinical presentation is polymorphic. The most common presentation is heart failure, but could be pulmonary embolism or tricuspid valve obstruction. We report here, the case of a 60‐year‐old man admitted for severe heart failure. The echocardiogram showed a voluminous and floating right atrial mass, appending to the interatrial septum and protruding into the right ventricle causing severe tricuspid regurgitation. Chest computed tomography scan demonstrated multiple distal pulmonary emboli. Surgical excision and tricuspid annuloplasty were successfully performed. Histological findings were typical of a benign myxoma. At follow‐up, there was a complete regression of heart failure signs.

Early migration of an Amplatzer muscular ventricular septal defect occluder device causing severe tricuspid valve obstruction

Percutaneous closure of perimembranous and muscular ventricular septal defects is becoming well established worldwide. We present the case of a 15-year-old girl with postoperative tetrology of Fallot and a residual ventricular septal defect that was closed with Amplatzer device complicated by early device migration and severe tricuspid valve obstruction.

Right atrial myxoma as a possible cause of hemorrhagic stroke and sudden death

Right atrial myxomas are rare primary tumors of the heart. They may remain asymptomatic or eventually cause constitutional signs and symptoms. Less frequently, obstruction of the tricuspid valve occurs, resulting in exertional dyspnea, syncope, or sudden death. Neurological manifestation as initial presentation of atrial myxomas is rarely, if ever, associated with right atrial myxomas and may be secondary to cerebral infarction, cerebral hemorrhage and, more rarely subarachnoid hemorrhage. We review the case of a previously unknown, middle-aged Nigerian man who presented to hospital with severe headache and sudden loss of consciousness. A clinical diagnosis of hypertensive hemorrhagic cerebrovascular accident was made. The patient died suddenly a few hours after presentation. Post-mortem examination revealed a small intracerebral hemorrhage in the left superior temporal lobe as well as a large right atrial myxoma, a ventricular septal defect in the muscular septum, and right ventricular hypertrophy. The liver showed fatty change while the kidneys showed evidence of benign nephrosclerosis. Right atrial myxomas may, therefore, be remotely considered as a cause of intracranial hemorrhage, especially in the presence of predisposing cardiac anomalies such as a ventricular septal defect. Similarly, being a known cause of right heart failure, sudden death, and other constitutional derangements, it may contribute significantly to disease outcome. Hence, it should be given due consideration in the differential diagnosis of cerebrovascular accidents.

Massive right atrial myxoma: An unusual presentation in an elderly patient

Primary heart tumors are rare with an estimated incidence ranging 0.0017–0.19%. Myxoma is the most prevalent primary heart tumor. The right atrium is an unusual location, occurring only in the 15–20% of myxoma cases. We describe the case of a massive right atrial myxoma causing right ventricular inflow and tricuspid valve obstruction. The tumor was detected by echocardiography and confirmed by abdomen-thoracic tomography. It was resected along with a section of tricuspid septal leaflet, followed by primary repair. In 2-year follow-up the patient is asymptomatic.

Massive right atrial myxoma presenting as syncope and exertional dyspnea: case report

Primary heart neoplasms are rare occurring with an estimated incidence of 0.0017-0.19%. Myxoma is the most prevalent primary heart tumor. The right atrium is an unusual localization, occurring only in 15-20% of myxoma cases. We report a rare case of a massive right atrial myxoma causing tricuspid valve obstruction and presenting as syncope and exertional dyspnea. This case illustrates the influence of myxoma's size, position and mobility as well as patient's body posture and respiration to the development of signs and symptoms. Three-dimensional echocardiography proved useful in surgery planning, allowing a better definition of the tumor outline and attachment.

Intraatrial extension of thyroid cancer: a case report.

A 61-year-old man, who was diagnosed with superior vena cava syndrome by papillary thyroid carcinoma, was referred to our hospital. A bulky thyroid tumor with tracheal invasion extended from the left neck to the right atrium without distant metastases. The risk of sudden death due to airway occlusion, tumor embolism or obstruction of the tricuspid valve led us to elect surgery. Extended resection of thyroid cancer was performed with cardiopulmonary bypass. Peritoneal dissemination was found via laparotomy. A histological diagnosis of anaplastic carcinoma arising from transformation of papillary carcinoma was made. After the operation, bilateral ureteral occlusion by peritoneal dissemination and multiple lung metastases were detected. The patient died with acute renal failure on postoperative day 12. Intraatrial extension of thyroid cancer is rare, and only 12 cases have been reported in the literature. We present a case of thyroid cancer with intraatrial extension.

A Case of Right Atrial Mass Associated With Hepatocellular Carcinoma

Right atrial metastasis occurs in 1 to 4% of patients with hepatoma, and the extension to intracavitary or metastasis of a tumor as a large mass rare. However, the high risk of progressive heart failure and sudden death from the tricuspid valve obstruction necessitates prompt diagnosis of intracavitary extension, and adequate intervention is needed to prolong a patient's life. A 49 year-old female was referred to our hospital for further evaluation of a liver mass, which was identified at a local clinic. The liver mass was confirmed as hepatocellular carcinoma with CT and celiac angiographies findings. She was treated with transarterial chemoembolization. Thirty-four months after discharge, a low density right atrial mass was noted incidentally with chest computed tomography while investigating a massive right pleural effusion for possible pulmonary metastasis. Echocardiography showed a huge inhomogenous echogenic mass at the right atrium. The present report describes a case of primary hepatocellular carcinoma with a intracavitary cardiac mass detected with two dimensional echocardiography.

Intracardiac tumor in a neonate causing complete tricuspid valve obstruction

] l ~ HABDOMYOMA is the most common intracardiac tumor 1 ~ in childhood and is frequently associated with tuberous sclerosis. These tumors are often multiple and may cause significant hemodynamic disturbances because of outflow obstruction or arrhythmias. The detection of rhabdomyoma has been improved by fetal sonography, but successful resection of such tumors is rare, t and the descriptions of intraoperative monitoiing have been limited. A case of a neonate with right atrial outflow obstruction who underwent successful tumor resection with the aid of biplane transesophageai echocardiogra: phy (TEE) is reported.

Right atrial thrombus in constrictive pericarditis

We describe right atrial thrombus complicated by tricuspid valve obstruction in a patient with constrictive pericarditis. This report highlights the role of surgical thrombectomy, and the investigation of constrictive pericarditis to exclude intra-cardiac thrombus.

Resection of right atrial lymphoma in a patient with AIDS

Although cardiac problems are common in acquired immunodeficiency syndrome, there is limited experience with heart surgery in this group of patients. We report a case in which a right atrial lymphoma was resected to alleviate tricuspid valve obstruction in a patient with AIDS. The patient did well for approximately 7 months. At that time, he developed multiple complications of AIDS and deteriorated rapidly; he died 8 months after operation. Cardiac surgery can be successfully performed in AIDS patients. However, the late outcome is compromised by the nature of the underlying viral infection.

Malignant thymoma causing tricuspid valve obstruction

A 57-year-old man presenting with a retrosternal mass was found to have a malignant thymoma. This was treated with surgery and radiotherapy. It recurred 5 years later as an intra-cardiac mass causing tricuspid valve obstruction.

Resection of Cavoatrial Renal Cell Carcinoma Employing Total Circulatory Arrest

Intracaval extension of renal cell carcinoma to the right atrium is a life-threatening presentation that may result in fatal tricuspid valve obstruction or pulmonary embolization. From 1981 to 1989 we treated 10 patients with such extension of tumor, the last 7 of whom underwent resection in which hypothermic circulatory arrest was used. No postoperative deaths, myocardial infarctions, or strokes occurred. Four patients were alive with no evidence of disease at 4, 10, 16, and 39 months after resection, and 1 patient was alive with pulmonary and spine metastases at 34 months after resection. Two patients died of metastatic disease at 7 and 12 months. In the absence of diffuse metastatic disease, lymph-node involvement, or invasion of contiguous organs, radical resection of cavoatrial hypernephroma may result in excellent palliation and possibly a cure.

Fatal Tricuspid Valve Obstruction due to a Large Infected Thrombus Attached to a Hickman Catheter

LONG-TERM home parenteral nutrition (HPN) has been associated with septic, mechanical, and metabolic complications.^1,2We recently observed a catheter-related complication that has not, to our knowledge, been reported in an adult. A large infected thrombus was attached to the tip of a Hickman catheter and obstructed the tricuspid orifice; it was probably the source of the patient's fever of undetermined origin, metastatic soft-tissue infections, and death. <h3>Report of a Case</h3> A 56-year-old woman with a history of arthritic symptoms was diagnosed to have progressive systemic sclerosis on the basis of Raynaud's phenomenon, sclerodactyly, finger ulcers, dysphagia, telangiectasis, antinuclear antibody (positive at a 1:4096 titer, nucleolar pattern), and rheumatoid factor (reactive at a 1:640 titer). During the next two years, her symptoms worsened. She was hospitalized three times in two months for recurrent bouts of intestinal pseudo-obstruction. A Hickman catheter was placed for HPN after efforts at enteral nutrition failed.

Right to left intracardiac shunt: A unique presentation of metastatic cardiac disease

A 54 year old man presented with signs and symptoms of severe hypoxemia. He had a history of a nasopharyngeal epidermoid carcinoma that was thought to have been totally eradicated 2 years earlier. He was found to have a right to left interatrial shunt through a patent foramen ovale due to tricuspid valve obstruction by a solitary cardiac metastasis. No other such reported case of a metastatic cardiac lesion could be found.

Right ventricular myxoma

We recently treated a patient with right ventricular myxoma and a clinical picture of pulmonary embolism and tricuspid valve obstruction who had successful removal of the tumor through the tricuspid valve via a right atriotomy.
