“…Left atrium is their preferable location, probably constituting up 60À80% of all myxomas, and the remaining cases of myxomas can occur in the right atrium, right ventricle or left ventricle and even some are biatrial atrial. 1,15 Cardiac myxomas in patients with Carney syndrome usually involve more than one cardiac chamber and unusual locations. 13 The three cases we reported all occurred in the left atrium and showed different symptoms in different patients.…”

Myxoma is the most common type of primary cardiac tumors, accounting for 50%-80% of them. Cardiac myxomas are difficult to detect due to the lack of specific signs and symptoms and even benign tumors can cause serious consequences. Cardiac failure, atrio-ventricular valve obstruction or the embolization phenomenon can quietly occur in patients with cardiac myxomas. Here, we report three extraordinary cases, each of which vary in the first symptom. One case involved a 66-year-old man who had no underlying heart disease but suddenly developed chest tightness and got out of breath after exercising. One case was a 36-year-old young woman with a two-year history of low blood pressure but suddenly suffered a stroke. The third case was a 42-year-old middle-aged woman who accidentally discovered a cardiac myxoma during the diagnosis and treatment of acute pancreatitis. Echocardiography revealed huge masses floating in their atriums. Under general anesthesia, all the patients underwent open-heart surgery and hematoxylin and eosinÀstained sections of the samples confirmed myxomas. Although most patients with cardiac myxomas lack of specific systemic symptoms, typical myxomas are relatively easy to diagnose. There are currently no effective medical therapeutic to inhibit tumor growth and surgical resection is the mainstay of treatment, which prevents a dreaded complication resulted from systemic and pulmonary embolisms.

“…Myxoma in the reported case was located in the left atrium, attached to the interatrial septum. About 75% (60-88%) of myxomas occur in the left atrium (the area of the fossa ovalis is the usual site of attachment), 15-20% (4-28%) occur in the right atrium [9,10]. Atypical locations, described in the literature, include: posterior or anterior left atrium wall, atrial appendage ridge, arising from the ostium of the coronary sinus, left ventricle (3-8%), right ventricle (3-6%), mitral valve (6,1 %), including chordae of the mitral valve, anterior or posterior mitral leaflets or mitral annulus, biatrial location (<2.5%) with extending tumor through the foramen ovale into the contralateral atrium, the aortic valve, biventricular tumors [9,10].…”

Patients having cardiac myxoma in a cardiac chamber other than the left atrium, presenting at a younger age, having multiple tumors in multifocal locations are at higher risk to be diagnosed with Carney complex, a familial disorder with spotty pigmentation of the skin and endocrinopathy.…”

Myxomas, being the most common primary benign tumor among all cardiac tumors, occur rarely with a very low incidence rate. Myxomas can cause various clinical manifestations or can be diagnosed incidentally. Some patients with cardiac myxomas are completely asymptomatic. Cardiac myxomas cause life-threatening complications, thus early diagnosis is imperative. We are reporting a case of atrial myxoma in a 38-year-old female without any significant past medical history, who came to our clinic for cardiology evaluation prior to plastic surgery. The elliptical mobile mass, located in the left atrium with its attachment to the interatrial septum, was diagnosed by transthoracic echocardiography. The patient was referred for surgery and a minimally invasive surgical approach was chosen. A histological report confirmed the diagnosis of myxoma. The patient recovered well. Three years of follow-up did not reveal any signs of recurrence of the tumor. We are also analyzing 20 previously published cases of asymptomatic myxomas and myxomas treated with a minimally invasive surgical approach, reported in the PubMed database for the last 20 years in the adult patient population (age 19 and over). The aim of this study is to highlight the asymptomatic presentation of cardiac myxomas and to underline the advantages of a minimally invasive surgical approach. In summary, asymptomatic cardiac myxomas are rare incidental findings. Attention to subtle symptoms during a physical exam and scrupulous history-taking can provide a clue to this diagnosis. Early diagnosis of cardiac myxomas is crucial to prevent life-threatening complications. Minimally invasive surgery is a promising alternative approach to standard open-heart surgery for treating cardiac myxomas, providing faster recovery and higher patient satisfaction with surgical care.

Myxoma is the most common type of benign cardiac tumor in adults. Myxoma can occur anywhere in the heart. The left atrium is the most frequent site of origin, specifically located on the left atrium side of the fossa oval in the atrial septum, followed by the right atrium, the right ventricle and left ventricle. But biatrial myxoma is extremely rare. Thoracoscopic resection of myxoma has become more common, but there are few reports on thoracoscopic surgery for biatrial myxoma. We present a case of a 72-year-old woman with biatrial myxoma, who presented with intermittent dyspnea for one week.Echocardiography revealed a medium echo in both the left and right atrium and was connected via the atrial septum. Computed tomography revealed a hypointense mass in both atria. Thoracoscopic resection successfully removed the tumors, and histological examination confirmed the diagnosis. Also, the patient was discharged six days after surgery. There was no evidence of tumor recurrence during the one-year followup period. Biatrial myxoma is rare. Surgical resection is the primary method for myxoma. Compared with the traditional medium thoracotomy, thoracoscopic surgery for myxoma has the following advantages: less trauma, keeping the integrity of the sternum, less bleeding, faster postoperative recovery, etc. Total thoracoscopic surgery for biatrial myxomas is effective and safe.
