BACKGROUND: Cardiac metastasis including the right ventricle from renal cell carcinoma is rare. No standard treatment for cardiac metastasis and recurrence in renal cell carcinoma has been established.
METHODS: We present the case of a 61-year-old man who underwent the resection of recurrent right ventricular metastasis caused by renal cell carcinoma following molecular targeted therapy. The first cardiac operation was performed for right ventricular metastasis due to renal cell carcinoma. The patient had a good postoperative course. Two years after the first operation, however, follow-up computed tomography revealed the recurrence of the right ventricular tumor and metastases in both lungs. Molecular targeted therapy was carried out and effectively controlled the lung metastasis but the right ventricular lesion remained unchanged, leading to reoperation. The recurrent right ventricular tumor was completely resected through a redo median sternotomy assisted by cardiopulmonary bypass. The patient had an uneventful postoperative course and was discharged on the 13th postoperative day. Follow-ups at 2 years showed no cardiac recurrence.
CONCLUSIONS: Surgical intervention was considered useful in managing the recurrence of right ventricular metastasis from renal cell carcinoma after molecular targeted therapy.

A patient with ventricular tachycardia (VT) and right ventricular (RV) metastatic diffuse large B-cell lymphoma had persistent RV gadolinium enhancement following chemotherapy and disease remission. Electrophysiology study demonstrated inducible sustained monomorphic VT requiring subcutaneous implantable cardioverter-defibrillator implantation. This highlights the arrhythmogenic potential of residual scar after resolution of cardiac masses.

A young patient, recently treated for squamous cell penile carcinoma, presented with acute myocardial infarction and severe heart failure. Despite repeatedly ruling out metastatic disease on imaging, surgery for a mechanical assist device revealed unexpected squamous cell metastasis in the pericardium. Consequently, palliative care was initiated.

Radioligand Therapy (RLT) in the form of [177Lu] Lu-DOTA-TATE (Lutathera®) is a promising treatment for pancreatic neuroendocrine tumors (pNETs) with cardiac metastasis. We present a patient treated with [177Lu] Lu-DOTA-TATE that showed shrinkage of metastasis after four treatments at 7.4 GBq every 8 weeks.

Melanoma is considered a masquerader of many diseases owing to its potential to metastasize to many organs. Several malignancies can metastasize to the heart including malignant melanoma. Historically, antemortem diagnosis of cardiac involvement of melanoma is not common, but with significant improvement in imaging modalities, the diagnosis can now be made early and accurately, aiding in treatment and improved survival. We present a case of a 36-year-old man with brief neurological symptoms and subsequent diagnosis of cerebrovascular accident (CVA). Cardiac imaging revealed incidental findings of right and left ventricular masses and lymph node biopsy, confirming metastatic melanoma. Cardioembolic etiology was suspected for his CVA. Prompt immunotherapy was initiated with improvement in his clinical condition.

Cardiac masses are currently studied using multimodality imaging. For diagnosis, different imaging techniques that can provide complementary information are used. Cardiac magnetic resonance imaging (MRI) has become a fundamental tool for this type of pathology owing to its ability to provide tissue characterization, spatial accuracy, and the anatomic relationships of the different structures. This study presents a series of four clinical cases with an initial diagnosis of a cardiac mass. All cases were evaluated at a single center, and patients were aged 57 to 72 years. An etiological study was conducted on all patients using different imaging techniques, including MRI. This study describes the diagnostic and therapeutic procedures of the four cases, which included two intracardiac metastases and two benign tumors. Cardiac MRI was decisive in the diagnostic process, determining the clinical decision-making in all four cases. Cardiac MRI has emerged as a pivotal technique in the diagnosis of cardiac masses. It can provide a highly accurate histological diagnosis without the need for invasive techniques.

A 50-year-old woman who had previously undergone right radical mastectomy presented with chest tightness and shortness of breath after physical activities. A cardiac mass and multiple hepatic lesions were successively detected. We first performed hepatic puncture biopsy. Histopathologic examination confirmed that the multiple hepatic lesions were venous malformations. Based on the imaging findings and previous reports in the literature, we boldly speculated that the cardiac mass was also a venous malformation. The cardiac venous malformation was successfully resected, and the postoperative pathology confirmed our suspicion.
