The First Manifestation of a Left Atrial Myxoma as a Consequence of Multiple Left Coronary Artery Embolisms

Abstract

A case of multiple embolisms in the left coronary artery as a rare first manifestation of left atrial myxoma is reported. A patient with embolic myocardial infarction and congestive heart failure was treated by percutaneous aspirations and balloon dilatations. Transesophageal echocardiography disclosed a villous myxoma with high embolic potential. Surgical resection of the tumour, suturing of a patent foramen ovale suture and an annuloplasty of the dilated tricuspid annulus was performed the third day after the admission.Recovery of the documented left ventricular systolic function can be explained by resorption of myxomatous material. The patient was discharged ten days after the surgery.

Acute myocardial infarction not attributed to coronary artery disease: A seldom initial presentation of a left ventricular myxoma

“…10 However, the real incidence of CA embolisms may be higher, due to a potential incomplete detection of all patients suffering from MI or sudden cardiac death. 11 In this context, abnormal, but non-specific, rhythm disturbances like atrial flutter/fibrillation, bundle branch block (right or left) are identified in 20%-40% of myxoma patients, while tachyarrhythmias are observed in about 24%-25.7% of the cases. 2 Gold standard management for symptomatic patients is immediate surgical en bloc tumor removal with clear margins, when technically achievable.…”

Large Left Atrial Myxoma Discovered During Restaging of Breast Cancer

“…Typically known for causing noticeable symptoms, myxomas rarely manifest without any apparent signs. 6 We present a rare and interesting case of a large asymptomatic left atrial myxoma incidentally discovered during breast cancer restaging studies.…”

Mixoma: causa infrecuente de lipotimia

“…Los tumores cardiacos son raros con una incidencia que varía de 0.002% a 0.02%. La mayoría es benigno (Novak M, et al;, con múltiples formas de presentación por lo que a pesar de su rareza es importante tenerlos como diagnóstico diferencial ante un paciente que presente sintomatología cardiaca sin factores de riesgo cardiovasculares.…”
