“…Also, the dare issue with lipoma does not reside in its histological characteristics but its intracavitary component. Thus, the presence of cardiac lipoma becomes lethal when it occupies the LV cavity, resulting in obstruction and compression, which eventually causes peripheral embolism, LV failure, and rhythm and conduction disorders (12)(13)(14). The patient's symptoms in the presented case were those of heart failure with dyspnea and peripheral edemas.…”

Cardiac lipomas, though extremely rare, are encapsulated tumors composed primarily of mature fat cells. Despite their benign character, cardiac lipomas can cause life-threatening complications by rapid growth. Cardiac lipomas, which are frequently located in the left ventricle (LV) or right atrium, can originate either from the subendocardium, subpericardium, or the myocardium. They are usually asymptomatic and carry a good prognosis during long-term follow-up; however, published reports show that untreated cardiac lipomas may be fatal when they cause arrhythmic or obstructive symptoms. In addition, several surgical options have been reported to obtain an appropriate operative view following poor visualization, primarily when tumors are located in the LV. Herein, we present a case of a pedunculated LV apical lipoma in a symptomatic patient successfully managed by surgical resection. We also discuss diagnostic modalities in surgical planning and the choice of surgical approach.

“…Moreover, the ages of the included patients ranged from 0.1-77.0 years, while the majority of patients (25/33) were aged ≥30.0 years. Most cardiac lipomas are asymptomatic and have a good prognosis; however, some giant cardiac lipomas can cause left ventricular inflow or outflow disturbances, left ventricular dysfunction or conduction system invasion ( 30 , 40 ). These conditions can induce dyspnea, presyncope, syncope or palpitations ( 30 , 40 ); however, the present study reported on a patient that presented with no etiologic chest pain, which could be considered as cardiac lipoma in clinical practice.…”

The present study described the case of a 22-year-old woman who had symptoms of left chest pain for >6 months, with further aggravation over 2 days. Computed tomography (CT) images of the mediastinal and pulmonary windows showed low-density shadows in the left ventricle. Echocardiography indicated a slightly stronger echo cluster in the left ventricle, with a range of ~29x30x35 mm, which was closely related to the lower wall and part of the posterior wall of the left ventricle. Contrast-enhanced ultrasound showed that the left ventricular mass was enhanced in a circular and dot-line shape, with a solid mass occupying the left ventricle and a rich blood supply. CT angiography revealed a nodule of size 27x27x24 mm in the left ventricle. During the operation, it was observed that the cardiac lipoma invaded the chordae tendinae and papillary muscle, and a valve replacement was performed. Postoperative examination revealed a piece of gray and anaplastic tissue, measuring 30x22x17 mm. The pathology of the specimen showed that the morphology of the left ventricular mass met the criteria of an intramuscular lipoma. The present study reported a cardiac lipoma involving the left anterior chordae tendinae and papillary muscle, with the patient showing only nonspecific symptoms. Early surgery should be applied to improve the prognosis of cardiac lipoma.

“…They are usually incidentally-discovered during cardiac investigations that are performed for other reasons. Symptoms such as dyspnea, pre-syncope, syncope or palpitations can occur if the tumor grows and causes LV inflow or outflow obstruction, LV dysfunction or invasion of the conduction system [2,[5][6][7]. Sudden cardiac death has been reported, but the true incidence is unknown given the rarity of this cardiac tumor [8][9][10][11][12].…”

Background: A cardiac lipoma is a rare primary cardiac tumor. They are usually asymptomatic and carry a good prognosis. Cardiac Magnetic Resonance Imaging (CMR) is the confirmatory investigation of choice. Case presentation: We present a case of left ventricular lipoma in an asymptomatic patient, which was successfully treated with surgical resection. Conclusion: Cardiac lipomas are rare and are usually benign. There is no guideline on the management of cardiac lipomas and treatment is individualized.
