Dear Editor,
We read with great interest the paper of Maraj et al. [1] dis-
cussing about the history of the primary cardiac tumors: we agree
with the Authors that the aim of the clinicians must be precocious
diagnosis even if clinical presentation would be heterogeneous.
Moreover, primary cardiac tumors are very rare and in many cases
patients may be asymptomatic so that incidental diagnosis is quite
common.
We present the case of a 28-year-old male referred for dyspnea
and palpitations that appeared about two months before. Clinical
management by general practitioners was not clear and he un-
derwent cardiac assessment only two months later. The trans-
thoracic echocardiography revealed the presence of a large cardiac
primitive mass. The magnetic resonance imaging (MRI) study
showed an 8×6.5×7 cm tumor arising from the free wall of the
right atrium, involving the proximal and the medium tract of a
patent right coronary artery (Fig. 1A–B). Tricuspid annulus, right
ventricle and superior vena cava were compressed (Fig. 1A–B).
Ascending aorta was very close to the lesion (Fig. 2A–B) and MRI
showed a 15 mm metastasis in the left lung (Fig. 2A–B). Intravenous
administration of gadolinium enhanced multiple necrosis areas
suggestive for a primary cardiac sarcoma. Considering the unfavour-
able location and the presence of metastasis, surgical excision was
not considered and chemotherapy (using bleomicin) was adminis-
tered such as palliative therapy. Recurrent pericardial serum-
haematic effusion required multiple pericardiocentesis and blood

transfusion. After 2 months the patient died because of thoracic
haemorrhage.
The particularity of our report is the large dimension of the cardiac
mass and the severe infiltration of the surrounding structures such as
tricuspid annulus, right coronary artery and free wall of the right
atrium. Previous reports [2–4] showed cardiac sarcoma originating
from the tricuspid annulus or with the infiltration of the right
coronary artery but this is the first report of a mass arising from the
free wall of the right atrium infiltrating surrounding structures. In this
case surgical resection was impossible for the large infiltration of the
heart. Our report confirms that cardiac sarcoma is a lethal tumor and
surgical excision, when possible, may be challenging without many
chances of success.
In conclusion, the “wait and see” approach in a 28-year-old patient
is somewhat hard to accept but understandable because of the
presence of a metastasis. However, the only way to improve prognosis
of malignant cardiac tumors is to increase the grade of suspicion in
order to increase the rate of an earlier diagnosis allowing for complete
resection. Echocardiography and cardiac magnetic resonance are
mandatory for complete assessment of the lesion and for the decision
making process. This paper supports the concept that when
symptoms such as dyspnea, palpitations and other cardiac related
are concomitant to signs and symptoms concerning possible malig-
nancy such as weight loss, the hypothesis of cardiac tumors should be
considered and loose time during the diagnostic process may cause
severe sequelae in the possibility of surgical resection of the lesion.
