Mixoma em ventrículo direito e valva tricúspide

Abstract

Mixoma em ventrículo direito e valva tricúspideRight ventricle and tricuspid valve myxoma CLINICAL DATA We present a case of a 15-year-old white female teenage weighing 47.3 kg, born in Anhumas, São Paulo State. A year ago started a weariness and tachypnea picture to mild efforts followed by cyanosed lips and extremities. When at rest she felt better. She was referred to her cardiologist at her home town, and she was diagnosed with a mass in the right ventricle. The use of aspirin was suggested. In our pediatric service, she appears to be in a good general health, eupneic and acyanotic at rest, hydrated, and rosy. Cardiac and pulmonary auscultations were normal, abdomen with no changes. Pulse was palpable and symmetrical in both upper and lower members. ELECTROCADIOGRAM An electrocardiogram showed a sinus rhythm with a rate of 88 bpm; SÂP at +60º, ÂQRS + 90º, and QTc of 0.42 sec. PR interval and the other segments were within normal limits; Anomalous conduction through the right branch was highlighted by RSR' pattern in V1.

Atypical size and location of a right atrial myxoma: a case report

“…They may arise in other locations, such as the right atrium (RA) (18% of cases) [5], and, more rarely, in the aorta, pulmonary artery, ventricles, vena cava, or even other organs [3,6]. The differential diagnosis is performed mainly between rhabdomyoma or thrombus [2].…”

“…There is a female predominance in the sporadic form [7]. Myxomas are usually pedunculated, solitary, and sporadic but may be associated with familial autosomal dominant syndromes (7% of cases) [6]. These familial forms have the following characteristics: they affect young male patients, they are multiple, and they have a risk of recurrence after surgical excision [4].…”

A Typical Bilateral Atrial Myxoma: A Case Report

“…Right atrial myxomas are uncommon, being three to four times less frequent than those located in the LA [3]. Multiple intracardiac myxoma accounting for less than 5% among all the cases, and the biatrial myxoma is fewer than 2.5% [4].…”

“…Right atrial (RA) myxomas are less common. Also reported in the literature, it could be found in the aorta, pulmonary artery, ventricles, vena cava, or even other organs [3]. …”

Myxoma pediculated from atrial septum invading atria and biventricular inlets

“…The radiological exam used for this diagnosis was the echocardiogram because it is a non-invasive exam and has an excellent sensitive. The histologic diagnosis was confirmed by pathological examination after operation, as it is shown in Figure 2 [ 3 , 4 ] .…”
