Congenital Solitary Left Atrial Mass

Rhabdomyoma in the absence of tuberous sclerosis presenting as a large solitary atrial mass is an atypical finding. We hereby present images from an infant with a fetally diagnosed large left atrial mass with no evidence of mitral valve dysfunction who subsequently developed persistent arrhythmias requiring surgical resection of the mass in the neonatal period.

Cardiac Myxomas

Abstract Background Cardiac myxomas are the most common benign primary cardiac tumours. The natural history of left cardiac myxomas is thought to be of slowly growing tumours. Cardiac myxomas are a heterogeneous group with a variable growth rate. They present usually with stroke, valve obstruction, or non-specific symptoms. Surgical resection is the effective treatment. Case summary This case report describes a 56-year-old hypertensive and dyslipidaemic female, when she was admitted in January 1990, complaining of loss of appetite, aches, pains, and palpitations. Her workup included a transthoracic echocardiography and transoesophageal echocardiography, which showed a left atrial mass attached to the inter-atrial septum, highly suggestive of left atrial myxoma. She was referred for surgical removal of the left atrial mass. However, she was reluctant to undergo surgery as she felt better. The patient was followed-up for almost 30 years with the left atrial mass confirmed as left atrial myxoma by cardiac magnetic resonance imaging. The left atrial mass became smaller in size and more calcified. Discussion Cardiac myxomas are a group of heterogeneous tumours, thought to be slowly growing. The growth rate of cardiac myxomas prior to diagnosis is not well known, as the vast majority is treated with surgical resection immediately after diagnosis. Our case showed the natural progression of an unoperated smooth-surfaced left atrial myxoma followed-up for almost 30 years, which slowly became smaller and more calcified.

Special Consideration

Abstract Two neonates with tuberous sclerosis and giant cell astrocytomas diagnosed soon after birth are described. During attempted surgical resection of their tumors, both infants developed refractory intraoperative cardiac arrhythmias and died. At autopsy, both patients had multiple cardiac rhabdomyomas. Subependymal giant cell astrocytomas rarely present in the neonate, but genetic implications and associated cardiac hamartomas warrant special consideration of these connatal tumors. Surgical considerations suggest that an operative approach to these tumors should be delayed beyond the neonatal period.

Defect Repair

Cardiac sarcomas have a high infiltrative and metastatic potential and are often associated with poor prognosis. These tumors are often identified incidentally by thoracic and cardiac imaging. However, when symptomatic, their presentation can differ based on the localized structural effects on the endocardium, myocardium, pericardium, and valves as well as on dynamic effects on the cardiac function. We report a case of a 61-year-old female who presented to the emergency room with recurrent chest pain, fatigue, and chronic anemia. A transthoracic echocardiogram demonstrated a left atrial mass attached to the septal wall and anterior leaflet of the mitral valve. The mass was further characterized by a transesophageal echocardiogram and cardiac MRI. The patient underwent a resection of the left atrial mass with mitral valve replacement (MVR) and atrial septal defect repair. MVR was later complicated by paravalvular leak leading to acute congestive heart failure. Tissue immune histology was consistent with dedifferentiated liposarcoma. Cardiac dedifferentiated liposarcoma is extremely rare with only few cases reported in literature. We attempt to review the clinical features, diagnosis, and management of cardiac sarcoma with great emphasis.

Early Results

Background: Proper visualization has always been the cornerstone for conducting proper cardiac interventions. Although many incisions have been described for mitral valve exposure, the feasibility of some comes at the expense of proper exposure. When it comes to a small left atrium, larger incisions may venture into critically situated structures, creating a heavy toll of increased morbidity and mortality. We aim to evaluate the safety and efficacy of a superior left atrium approach for mitral valve interventions and left atrial mass resection, particularly in a small left atrium.Methods: We present our experience and early results as a retrospective study conducted at Cardiothoracic Surgery Department, Ain-Shams University, Cairo, Egypt. A total of 85 patients underwent mitral valve interventions and left atrial mass resection through limited incision in the left atrial dome.Results: The study included 29 female patients and 56 male patients with a mean age of 42.56 ± 7.39 years. Twenty-seven patients were NYHA class I-II and 58 patients were class III-IV. Mean ejection fraction was 55.47 ± 8.56. Three patients had mitral valve repair, 67 patients had mitral valve replacement, and 15 patients had resection of left atrial myxomas. Preoperative atrial fibrillation was present in 27% of the patients. Two patients had new incidence of atrial fibrillation, one patient had new atrial flutter, and one patient had complete heart block, requiring a permanent pacemaker. No mortality occurred in the series, and three patients needed re-exploration for bleeding.Conclusions: Limited left atrial roof incision provides a safe and feasible exposure for conducting mitral valve interventions and resection of left atrial masses, especially in cases with a small left atrium.
