| Abstract: | An 11-year-old mixed breed dog was presented with exercise intolerance and syncope. At admission, transthoracic echocardiography revealed myxomatous mitral valve disease (MMVD) associated with severe left atrial (LA) enlargement and moderate anechoic pericardial effusion with a hyperechoic density suggestive of a thrombus. Rupture of the LA free wall secondary to MMVD was suspected, and medical therapy with furosemide and pimobendan was initiated. After one month, recheck echocardiography showed mild anechoic pericardial effusion and an acquired atrial septal defect with a left-to-right intracardiac shunting flow. In light of the dog's history, the latter finding was suspected to be secondary to a further rupture of the LA wall due to MMVD, this time affecting the interatrial septum. The images described here allow us to suspect that sequential LA wall ruptures developed over time in the same subject affected by MMVD, a clinical presentation not previously described in veterinary medicine. |
