“…Surgery involves resection of the accessory atrial membrane and it is generally well tolerated with over 90% of patients remaining symptom-free five years after repair [13]. Patients will require long-term serial echocardiograms to assess for progressive pulmonary vein stenosis and left atrial tissue overgrowth [14]. …”

There are multiple cardiac etiologies for wheezing and respiratory distress which require a high degree of suspicion for the pediatrician to diagnose. We present a case of a patient with a history of long-standing mild persistent asthma with minimal improvement on controller and bronchodilator therapies who presented to the emergency room with acute respiratory distress. When he demonstrated a lack of improvement with traditional respiratory therapies, additional etiologies of respiratory distress were considered. Ultimately an echocardiogram was performed, which revealed the diagnosis of cor triatriatum. He underwent surgical resection of his accessory membrane and has had no additional symptoms of asthma since repair.

“…As such, only type IA (classic cor triatriatum where an accessory atrial chamber receives all PVs and connects with the left atrium) and type IIIA1 (subtotal cor triatriatum with an accessory atrial chamber receiving part of the PVs and communicates with the left atrium, with the remaining PVs connecting normally) are amendable for percutaneous intervention. In addition, approximately 75 % of patients in large surgical series undergoing operative treatment also underwent additional surgical procedures [ 4 , 5 , 14 ]. When cor triatriatum is associated with other cardiac abnormalities requiring surgical intervention, operative therapy naturally remains the treatment of choice.…”

“…When this opening is significantly obstructive, it causes restriction of pulmonary venous return and possibly pulmonary hypertension, mimicking the pathophysiology of mitral stenosis. In these cases, surgical resection of the membrane is indicated, with excellent long-term outcome [ 4 , 5 ].…”

BackgroundCor triatriatum is a rare congenital cardiac abnormality, consisting of an obstructing membrane between the pulmonary veins and the mitral valve in varying patterns. The entitiy can mimick the pathophysiology of mitral stenosis, necessitating surgical resection. Occasionally, percutaneous balloon dilatation of the membrane has been successfully performed.Case presentationWe report two cases with cor triatriatum where intraoperative balloon dilatation of the membrane was attempted followed by surgical resection, to explore the feasibility of cathether-based interventional strategies for cor triatriatum.ConclusionsVarious anatomical variations exist of cor triatriatum, depending on the drainage of the pulmonary veins and the drainage of the proximal chamber in the right or left atrium. Only isolated forms of cor triatriatum where all pulmonary veins ultimately drain into the left atrium can be recommended for percutaneous strategies. In addition, several anatomical characteristics should be considered to predict technical success of cathether-based interventional strategies, such as the location of the membrane, the degree of pulmonary vein stenosis, the extent of calcification, and the presence of other (congenital) cardiovascular abnormalities. Furthermore, long-term efficacy of these strategies remains to be confirmed. As such, surgical treatment of cor triatriatum remains the mainstay of treatment in adult patients, especially when other cardiovascular anomalies are present which require surgical correction.

“…In CTS, long-standing inflow obstruction of the left ventricle can increase the risks of backflow pulmonary venous congestion and pulmonary artery hypertension. The reversibility of pulmonary congestion should be ensured before surgery in patients with CTS [24]. Pulmonary congestion and pulmonary arterial hypertension are never present in patients with CTD.…”

“…Therefore, transesophageal echocardiography-guided volume administration is crucial to maintain pulmonary flow in patients with CTD [25][26][27]. Other management options, including balloon septoplasty, balloon septostomy, and observation, can act as a bridge to surgery [24,28]. Generally, medical management has no role in the treatment of CTS and CTD, but it is unclear if CTS patients require anticoagulation to prevent stroke.…”
