Six-Year Follow-Up of an Octogenarian With a Left Atrial Myxoma: Case Report

Miguel Bernardino Antunes Vicente et al. Tânia Amaro Elsa Fernandes

Abstract

Myxoma is the most common primary cardiac tumour, especially in adults. However, reports on this nosological entity in patients over the age of 80 are scarce in the medical literature. Echocardiography is a useful diagnostic tool for detecting cardiac myxomas. These tumours are usually surgically removed soon after diagnosis, limiting knowledge of their natural evolution. In this report, we describe the case of an 86-year-old woman who had been followed irregularly for arterial hypertension since 2016, when an echocardiogram showed a left atrial myxoma adhered to the interatrial septum, initially without impairment of the mitral valve (MV) or obstruction of the pulmonary veins (PV). The patient refused surgical removal at the time. Six years later, she was hospitalized for urinary sepsis. A new echocardiogram revealed an increase in the size of the myxoma, which occupied around 80% of the left atrium (LA), obstructing the PV and MV. New suggestion of surgery was refused by the patient.

Primary neoplasms of the heart. Clinical and histological presentation of 50 cases

Fábio Fernandes et al. Helena N. Soufen Barbara M. Ianni Edmundo Arteaga … Félix J. A. Ramires Charles Mady

OBJECTIVE: To analyze clinical and histologic findings of 50 patients with primary neoplams of the heart in a tertiary referral center. METHODS: From 1980 to 1998, we retrospectively analyzed 50 patients, 32 of whom were females, whose ages ranged from 9 to 73 years (mean age = 44.16±18 years). RESULTS: Most tumors were located in the left side of the heart (72%), myxoma being the most common (84%) histologic type. The other histologic types found were as follows: fibroma (4%), lipoma (2%), rhabdomyosarcoma (2%), hemangioma (2%), sarcoma (2%), angiosarcoma (2%), and lymphoma (2%). Diagnosis was established by echocardiography in 94% of the cases. Clinical findings were as follows: dyspnea (36%), weight loss (20%), palpitations (18%), chest pain (16%), fever (8%), and arthralgia (6%). All patients with thromboembolic phenomena (10%) had left atrial myxoma. Approximately 20% of the patients were asymptomatic at the initial clinical assessment. CONCLUSION: Primary cardiac tumors are a rare entity with diverse clinical and histologic findings, requiring, therefore, a high level of clinical suspicion.
