Abstract

Atrial myxomas are the most common benign cardiac neoplasms. Although the majority occur in the left atrium (LA) and are attached to the interatrial septum (75–80 % of cases), they can arise from any part of the LA and the cardiac chambers. We report the case of a 65-year-old woman who presented with features of worsening dyspnea and persistent headache. During transthoracic echocardiography, a suspected cardiac myxoma was found arising from the posterior wall of the LA.

Zusammenfassung

Atriale Myxome stellen die häufigsten benignen kardialen Neoplasien dar. Obwohl die Mehrzahl der Myxome im linken Vorhof („left atrium“, LA) auftritt und dem interatrialen Septum anhaftet (75–80 % der Fälle), könnten sie an jeder Stelle des LA und den Herzkammern entstehen. Die Autoren berichten über den Fall einer 65-jährigen Frau, die sich mit Symptomen einer sich zunehmend verschlechternden Dyspnoe und persistierenden Kopfschmerzen vorstellte. Während der transthorakalen Echokardiographie (TTE) wurde der Verdacht eines kardialen Myxoms bestätigt, das an der Hinterwand des LA entstanden war.
