Patient with Atrial Myxoma and Signs of Obstruction of the Left Ventricular Outflow Tract

Antonio Fernando Diniz Freire et al. Alexandre Anderson de Sousa Soares Tatiana de Carvalho Andreucci Torres Leal Mucio Tavares de Oliveira Junior Alexandre de Matos Soeiro

Female patient, 45 years-old, reported dyspnea on routine efforts with 6 months of evolution with dry cough. Previously healthy she refused to take regular medication. According to the physical examination, she had a heart rate of 105 bpm, blood pressure of 90x60mmHg, respiratory frequency 30 incursions per minute, arterial saturation of 88%, slow capillary filling time, rhythmic sounds, diastolic rumble murmur (+++/6) in mitral focus and bibasal pulmonary crepitations. Chest X-Ray showed a discreet widening of the mediastinum. Chest CT was performed to evaluate the mediastinum and pulmonary parenchyma and an intracardiac mass was found. It evolved with hypotension and worsening of pulmonary congestion.

Emergency echocardiogram showed a moving rounded hyperechoic image in the left atrium, measuring 66x36mm with a pedicle adhered to the membrane of the oval fossa dislocating to the left ventricle (LV) during systole causing hemodynamic repercussion (signs of LV outflow tract obstruction). The patient underwent emergency surgery. Retraction of the tumor revealed a cleft in the anterior cusp of the mitral valve and it was closed. In the immediate postoperative, the patient developed cardiogenic shock refractory to vasoactive drugs; an intra-aortic balloon was implanted, but the patient died 30 hours later. Anatomopathological confirmed the diagnosis of a myxoma: 7.5×4.6×3.4cm. In conclusion, the atrial myxoma with obstruction of the outflow tract of the LV is rare, its clinical manifestations can mislead the evaluator, clinical suspicion and the correct use of propaedeutic are essential for early diagnosis and successful clinical treatment.

Case Report

Giant Left Atrial Thrombus with Double Coronary Vascularization

Ciambelli Giuliano Serafino et al. Mariana Lins Baptista Vitor Emer Egypto Rosa Antonio Sérgio de Santis Andrade Lopes … Tarso Augusto Duenhas Accorsi Flávio Tarasoutchi

Introduction

Rheumatic valvular disease, especially mitral stenosis (MS) and atrial fibrillation (AF), are the main factors related to the formation of left atrial (LA) thrombi^–. Its incidence can range from 16 to 64%, and the most affected site is the left atrial appendage^,.

Systemic embolism is responsible for 10 to 45% of the complications, being the most frequent clinical presentation. Despite being rare, the mechanical mitral valve obstruction caused by thrombus may be considered as potentially severe, especially among those patients with previous MS. The clinical manifestations of this condition are variable, presenting from worsened functional class (NYHA) to cardiogenic shock.
