“…The commonly accepted explanation is that of a histologically benign tumor developed from "pluripotent subendocardial embryonic vestigial remnants, usually sequestered in the limbic region of the fossa ovale" of the interatrial septum (AIS) [6]. The left atrium represents 75% to 90% of myxoma locations, implantation is mainly on the interatrial septum, mitral location is very rare [7]. Intracardiac myxoma is a pathology characterized by a very large clinical polymorphism which can cause diagnostic delay, although embolic accidents represent 10% of cases [8].…”

Introduction: Cardiac myxomas represent the most frequent forms of primary tumors of the heart. The most frequent location is the interatrial septum. We report the clinical case of a myxoma of the left atrium and discuss its epidemiological and therapeutic aspects through a review of the literature. Observation: This was a 41-year-old female patient who presented with sudden rotational dizziness associated with vomiting. MRI revealed multiple punctiform bilateral supra and subtentorial strokes of different ages, recent and semi-recent, suggesting an embologenic etiology. Transesophageal echocardiography found a large pedunculated, homogeneous, avascular tumor hanging from the interatrial septum. The patient is operated on urgently under cardiopulmonary bypass for resection of a large tumor located in the left atrium. The pathological examination concluded with the diagnosis of myxoma of the left atrium. The postoperative follow-up was straightforward and the patient was discharged from the hospital via home hospitalization. Conclusion: The diagnosis of cardiac myxomas is suspected in the presence of symptoms associated with echocardiographic images of intracardiac masses and confirmed by histological study. Embolic accidents are one of the formidable complications of myxomas. Surgical management is urgent, especially in the presence of predictive morphological features of embolism on echocardiography.

Of all benign neoplasms of the heart, cardiac myxomas (CM) are found in 50-90% of cases. National Amosov Institute of Cardiovascular Surgery of the National Academy of Medical Sciences of Ukraine has experience in surgical treatment of 968 heart tumors. Of these, CM was observed in 868 cases. The aim. To conduct an analysis of the frequency of detection of complicated forms of CM, to present the causes and methods of diagnosis and surgical treatment of these complications. Material and methods. Pathology of the valvular apparatus combined with CM occurred in 70 (8.1%) patients: an isolated lesion of the mitral valve (MV) was observed in 27 (38.6%) patients, concomitant relative insufficiency of the tricuspid valve (TV) was found in 10 (14.3%) cases. Results. During the surgical treatment of valvular pathology, we performed valve replacement in 15 (21.4%) patients (MV in 12, TV in 1, aortic valve [AV] in 1, AV + MV in 1 patient), reconstructive operations with a positive functional effect in 50 (71.4%) patients, and isolated tumor removal from the valve apparatus in 5 (7.1%) cases. Relapses after surgical treatment of CM in our cohort of patients occurred in 1.8% cases. Among patients with sporadic myxomas of the heart, recurrence was observed in 13 cases (1.5%). If the principle of radical removal of CM followed, relapses occurred in 1.3% (10 cases out of 772). In 7 cases of myxoma syndrome, the recurrence rate was 42.5%. Embolic complications of the course of CM were determined in 58 (6.7%) cases. Damage to cerebral vessels was found in 46 (77.9%), embolisms of peripheral vessels in 10 (16.9%), and embolisms of coronary arteries in 2 (5.1%) patients. In 41 patients with CM (4.2%), a significant lesion of the coronary arteries was found, which required surgical intervention. To correct the pathology of the coronary vessels, the following was performed: stenting in 3 cases (7.3%), coronary bypass surgery in 35 (85.4%), dissection of the muscle bridge that narrowed left anterior descending artery in 2 (4.9%), left ventricular aneurysm plastic surgery in 1 case (2.4%). Conclusions. Calcium changes in left atrial myxoma were most often accompanied by mechanical damage to the leaflets and chordal apparatus of the mitral valve. Hyperthermia was a frequent manifestation of CM (56.8%). In isolated cases, the temperature reaction may be associated with the tumor infection process.
