Surgical Treatment of Heart Mixomas: the Analysis of 10 Years’ Experience

Introduction. Primary cardiac tumors are rare, and the autopsy detection rate does not exceed 0.003%. Approximately 80% of primary heart tumors are benign, 50% of them are myxomas. Diagnosis of cardiac tumors at present in the presence of transesophageal echocardiography is not difficult in most cases. Surgical treatment of mixomas became possible after the introduction of open-heart surgery under cardiopulmonary bypass into clinical practice. After verification of the tumor, its surgical removal is indicated. In the practice of large cardiac surgery clinics, the experience of radical treatment of heart neoplasms is relatively small; therefore, the analysis of tactical approaches and results of operations in this pathology is of absolute interest.Aim of study. To present an analysis of 10 years’ experience in surgical treatment of cardiac mixomas. Material and methods The results of treatment of 58 patients with myxomas who underwent surgical removal of the neoplasm of the heart are presented.Results. Hospital mortality after surgical removal of myxoma was 1.7%, 1 patient died. All patients, we have the long-term period data about, noted a significant improvement in well-being, a decrease or disappearance of dyspnea at rest and/or during exertion, and no recurrence of myxoma was noted. Conclusion. The data obtained indicate, on the whole, good immediate results and high quality of life of patients in the long-term period operated on for heart mixomas.

Left Ventricle Intramuscular Haemangioma

Cardiac haemangiomas are rare cardiac tumours that are usually asymptomatic and detected incidentally while imaging the heart with echocardiogram. Cardiovascular magnetic resonance (CMR) is a non-ionising imaging modality that allows the diagnosis of cardiac haemangiomas prior to surgery. We report a 36-year old male patient who was referred to the Adult Cardiology Clinic at the Royal Hospital, Muscat, Oman, in 2006 with a history of a left ventricle mass detected on echocardiogram. Further assessment of the mass by CMR revealed that the mass within the left ventricle apical septum contained features that were consistent with a cardiac haemangioma. Due to the surgical risk of ventricular septal defect and the stability of the mass, the patient was managed conservatively and upon followup the patient’s condition remained stable.

Immunohistochemical Diagnosis of Primary Cardiac Leiomyosarcoma in a Latin American Patient

Primary cardiac malignancies are rare entities. Although sarcomas enclosed the main group of malignant heart neoplasms, primary cardiac leiomyosarcomas are extremely rare and constitutes less than 8% of cardiac tumors. Leiomyosarcoma usually originates from the pulmonary veins and have a worm-like shaped structure. In this article, we present a case of a 40-year-old Hispanic man diagnosed with a cardiac tumor who underwent surgical resection, during pathological examination the tissue samples were consistent with a malignancy of mesenchymal origin that contained irregular bundles of spindle cells. Subsequent immunohistochemical study categorized the mass as a primary heart leiomyosarcoma with positive smooth muscle actin and muscle specific actin. As usual in this type of malignancy, patient's clinical status declined overtime, recurrence was diagnosed two months after surgery, and four months after the procedure the patient was discharge for palliative care.
