“…After reviewing the literature, only one case of RA lipoma treated via a minimally invasive cardiac surgery technique was found (16). The main particularities of the case were the absence of clinical signs considering the dimensions of the tumor (6.5x5.5x3.5 cm; no right ventricular filling abnormalities) and the minimally invasive cardiac surgery CMR technique, which was also permissive for rapid recovery of the patient.…”

“…Large cardiac lipomas can lead to complications such as obstruction of ventricular outflow tract, electrical disorders, embolism or pericardial effusion (10,12,13,17). Obstruction of right ventricular outflow tract was reported in 11 out of 26 patients (42%) diagnosed with RA lipoma (2,(16)(17)(18)(19)(20)(21)(22)(23)(24)(25).…”

“…The present literature review showed that 23 out of 25 patients (92%) underwent surgery. Among these patients, only 1 out of 23 received a minimally invasive approach in 2021 (16). Minimally invasive surgical techniques should be considered in certain patients with cardiac lipoma in the future.…”

Cardiac lipomas are generally asymptomatic even in large dimensions. Echocardiograms can identify tumors, but cardiac magnetic resonance imaging or cardiac computerized tomography can differentiate cardiac lipomas from other cardiac tumors. The present study is a case report of an asymptomatic 30-year-old man diagnosed with atrial lipoma. The patient received cardiac surgery and the intervention consisted of exclusion of the right atrial (RA) tumor and reconstruction of the right atrium with 'XenoSure' patch in extracorporeal circulation through a minimally invasive approach. A short PubMed literature review was performed and 26 cases of RA lipomas with available details were found. Cardiac tumors may cause clinical presentation through different pathways. Symptoms related to an RA lipoma were present in 21 out of 26 patients (80%). The symptoms varied greatly, dyspnea being the most common of them. In one case, the lipoma was found during the autopsy of a patient after sudden death. Large cardiac lipomas can lead to complications such as obstruction of ventricular outflow tract, electric disorders, embolism or pericardial effusion. Obstruction of the right ventricular outflow tract was reported in 11 out of 26 patients (42%) diagnosed with RA lipoma. Generally, atrial lipoma can have various sizes. The most useful imaging technique was transthoracic echocardiography. Accurate diagnosis and evaluation of cardiac lipoma is dependent on multimodality imaging methods, including cardiac magnetic resonance. Surgery is the treatment of choice, but the risk-benefit ratio must be considered, and shared decision making must be taken into account. The present review data showed that 23 out of 25 patients (92%) underwent surgery. Among these patients, only 1 out of 23 received a minimally invasive approach in 2021. Cardiac lipomas are rare entities, usually asymptomatic, that can occur at any age. The most useful diagnostic method of cardiac tumors is echocardiography, but nuclear magnetic resonance can also specify the type and characteristics of tumors.

“…The case shows that prompt diagnostic workup is essential in patients with TIA. Myxomas should be excised without delay, however, excision should be performed with the highest urgency in irregular tumors that have already led to embolic complications [1,4]. Evidence of tumor vascularization may also lead to alterations in the resection strategy.…”

Cardiac tumors present substantial diagnostic challenges due to their diverse manifestations and similarity to other cardiac pathologies. Cardiac lipomas are rare tumors that originate from adipose cells and can develop in any location within the heart. Cardiac lipomas account for 2.4% of all primary cardiac tumors. Most lipomas are located within the cardiac chambers. Among the lipomas occurring within the cardiac chambers, the most common localization is the right atrium. Currently, the gold standard for imaging cardiac tumors is cardiac magnetic resonance (CMR). Despite the significant advantages of CMR, cardiac computed tomography angiography (CCTA) continues to be a valuable technique when CMR is either unavailable or contraindicated. In some cardiac tumors, CCTA can identify the type of tumor. A classic example of this type is a lipoma. We present images of a large interatrial septal lipoma filling the right atrium diagnosed by CCTA in a 57-year-old female Caucasian patient. In summary, CCTA effectively identifies lipomas’ characteristic features and provides crucial information for appropriate management.
