Syncope as initial manifestation of mixoma atrial

Abstract

Introduction: Primary heart tumors have a prevalence of 0.02% (200 cases per million/inhabitants), 75% of
them are benign, of these myxomas are responsible for 50% of cases. Initial symptomatology is usually
nonspecific depending on the location of the tumor and the presence of hemodynamic alterations, isolated
syncpe may be a rare onset of this atrial tumor. 

Objective: Describe the clinical case of an atrial myxoma in a patient without associated risk factors, who has
an episode of syncpe with no cardiovascular symptomatology.

Material and methods: A descriptive, retrospective study was conducted, clinical case presentation with
diagnosis of atrial myxoma.

Results: It describes the clinical evolution of a 63-year-old patient diagnosed with left atrial myxoma after
presenting a classic sync frame hours before admission. Despite the great initial symptomatic variability, it is
important to have a high rate of suspicion for a timely diagnosis and avoid its potential complications, in the
case presented its timely detection allowed us to provide adequate clinical management and evidenced by its
favorable evolution.

Conclusions: Intracardiac tumors should be considered as emergencies in the field of heart surgery because
they involve imminent sudden death. In the presence of a syncope without the obvious neurological cause
being determined, it is necessary to rule out primary cardiac pathology. Transesophageal echocardiography is
an important pillar in diagnosis. Surgical treatment is of choice and its long-term prognosis and quality of life
is good.
