“…Though cardiac masses are in part discovered at autopsy (16)(17)(18)(19) or incidentally following X-rays, diagnosing LV lipomas based on medical history, auscultation, and even X-ray alone is challenging. Hence, more dedicated imaging is warranted to characterize the mass.…”

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.

“…[ 24 ] The electrocardiogram may show nonspecific ST-T changes. [ 2 , 4 , 5 ] As it grows, the LV lipoma occupies a larger space, with possible serious consequences through an effect on adjacent cardiac structures or obstruction of the LV cavity. At that time, clinical symptoms such as cardiac murmurs, arrhythmias, fainting, or palpitations [ 6 ] may be caused by obstruction of the LV inflow or outflow tract, impairment of cardiac valve function, and involvement of conductive tissue.…”

Left ventricular lipoma resected using thoracoscope-assisted limited sternotomy

2018

Rationale:A cardiac lipoma is an uncommon primary tumor, with a reported incidence ranging from 2.9% to 8% among all benign cardiac tumors. Although the prognosis in most asymptomatic cases is good during longterm follow-up, some reports have shown that untreated cardiac lipomas may be fatal when they cause arrhythmic or obstructive symptoms.Patient concerns:We present a rare case of left ventricular (LV) lipoma. The mass measured 25 mm 10 mm, with a pedicle on the LV posterior wall near the apex.Diagnoses:The patient was diagnosed as left ventricular lipoma using echocardiography.Interventions:The LV lipoma was resected using thoracoscopy-assisted limited sternotomy.Outcomes:Histopathologic examination was consistent with lipoma. No signs of recurrence were detected on an echocardiogram during a 3-month follow-up period.Lessons:We performed a comprehensive review of relevant literature and summarized the known 21 cases from 1980 to 2017. LV lipoma may present with or without symptoms, and endoscopic resection may be a good alternative to open surgery.
