Surgical Treatment of Primary Intracardiac Myxoma: 20-Year Experience in “Shahid Modarres Hospital”—A Tertiary University Hospital—Tehran, Iran

Abstract

Although cardiac tumors are not common they may vary in terms of race and surgical approach in different countries. Method. Patients data of 20 years was collected and evaluated in the “Shahid Modarres Hospital”—a tertiary university hospital—Tehran, Iran. Results. 42 patients with cardiac myxoma (all cases in 20 years) were included in study, 17 males and 25 females, age difference: 13 to 76 years (mean 50.6). Most of patients were in functional classes I, II. 35 patients complained of dyspnea and 3 patients had embolic events. 97.6% of tumors were primary (41 patients) and one tumor was recurrent (2.4%), 85.7% of tumors (36 cases) were located in LA, and 88.1% of tumors (37 cases) were pediculated. 40 patients (95%) had one tumor. In 22 patients (52.3%) after tumor resection septal defects were repaired primarily while in 18 patients (42.8%) the defects were repaired with pericardial patch and In one patient, tumor resected without any septal defect. Mean tumor size was about 5.22 cm (range of 2.2 to 8.2 cm). Postoperatively, 33 patients discharged from hospital without any complication. Discussion. The research reveals that patients' age and gender were similar to that of other studies in other countries while tumor's incidence seems to be higher. 3 patients were diagnosed after remote embolic event and one patient was diagnosed after MI reflecting relatively high tumor complications and late diagnosis. Conclusion. In our study mean time from diagnosis to operation was too long. The patients had more preoperative embolic events and complication. However, size of myxoma and location of that was as same as its rate in the other literature. As recommendation we suggested that in all patients with vague chest pain or remote embolic events cardiac myxomas should be ruled out.

Disappearing “Myxoma”: Left Atrial Thrombus Masquerading as a Myxoma

“…We considered left atrial myxoma as an alternate diagnosis because of the globular and pedunculated appearance of the mass on the anteromedial aspect of the left atrium. Fatigue and dyspnea with or without palpitations although nonspecific, are the most reported presenting symptoms in patients with myxoma [1]. Our patient presented with a three-month history of dyspnea and fatigue, which was worse than his baseline symptoms in the setting of treated COPD and heart failure.…”

“…The patient was in normal sinus rhythm throughout his hospitalization; he did not have a history of atrial tachyarrhythmias and did not have stenotic atrioventricular valves [8]. Myxomas are the most common nonmalignant cardiac tumors [1]. We considered left atrial myxoma as an alternate diagnosis because of the globular and pedunculated appearance of the mass on the anteromedial aspect of the left atrium.…”

“…Cardiac myxomas are the most common primary cardiac tumors [1]. They account for approximately 75% of all primary cardiac tumors, they are benign, and are often present in the third to sixth decade of life [1][2].…”

“…Cardiac myxomas are the most common primary cardiac tumors [1]. They account for approximately 75% of all primary cardiac tumors, they are benign, and are often present in the third to sixth decade of life [1][2]. Depending on the size and location of the tumor, cardiac myxomas may present with no specific physical exam manifestations, or with nonspecific heart failure symptoms including dyspnea, fatigue, or orthopnea.…”

Recurrent Cardiac Myxoma Treated by Orthotopic Heart Transplantation: A Case Report and Literature Review of Heart Transplantation for Primary Cardiac Tumor

“…Two of the most feared consequences of CM are systemic embolism and postoperative recurrence. Studies found that the recurrence rate of CM is around 2-7% [ 1 , 3 , 4 ]. The incidence of recurrent CM was found more commonly in Carney complex and patients who were presented with multiple lesions, positive family history, younger age, and incomplete resection [ 3 , 5 ].…”
