Cor triatriatum: Clinical presentation and surgical results in 12 patients

Adult Cor Triatriatum Presenting as Cardioembolic Stroke

“…Cor triatriatum is a rare congenital cardiac malformation in which a fibromuscular membrane divides the left atrium (LA) into two distinct chambers (1). The hemodynamics of the cor triatriatum is similar to that of mitral stenosis and the most common presenting symptoms of cor triatriatum in adults are dyspnea, hemoptysis, and orthopnea as a result of the obstructive function of the intra-atrial membrane (2).…”

Cor Triatriatum Sinister in a French Bulldog

“…CTS was firstly described in human beings by Church in 1868 [1] and in the domestic cat by Gordon et al more than a century later [14]. Regarding canine species, only the dexter form has been reported [3,4].…”

“…It is among the rarest developmental cardiac disorders reported in people [1,2], dogs [3], and cats [4][5][6]. Cor triatriatum sinister (CTS) and dexter (CTD) consist of left or right atrium, respectively, divided into two chambers by a fibrous membrane.…”

“…If the membrane's foramen is large, the disease may show a benign course as seen eventually in adult humans with the classic type [8,11,12]. Since 1990s, the transthoracic echocardiography became the first choice imaging technique for the diagnosis of CT due to its high accuracy [1,9,10,13]. This technique is essential not only to establish the diagnosis, but also to assess hemodynamic repercussions and to document eventual associated defects [8].…”

“…The diagnosis is based on 2D echocardiography (2), or magnetic resonance imaging (MRI) or computed tomography (CT) scans (3).…”
