N2 - BACKGROUND: Malignant cardiac tumours are rare entities that cause severe morbidity and mortality. Possible treatment options vary between surgical removement, (immuno-) chemotherapy, and palliative care, whilst diagnostic workup comprises of imaging and histopathology analysis. Excimer laser sheaths are a new possibility to extract significant tissue samples to offer adequate treatment.CASE SUMMARY: A 67-year-old Caucasian female presented with progressive shortness of breath, new onset of fevers, weight loss, and recurrent night sweats. She showed signs of upper venous stasis.Cardiac imaging revealed an obstructive, hypoperfused right atrial mass superior to the tricuspid valve and a sessile structure at the mitral valve. Guideline-directed therapy for endocarditis was started subsequently.A conventional intracardiac biopsy of the tumour was unsuccessful, but an off-label approach using an excimer laser sheath as bioptome leads to the diagnosis of a diffuse large B-cell lymphoma. Immuno-chemotherapy was commenced, leading to reduction in tumour size and rapid improvement in the quality of life.DISCUSSION: Intracardiac biopsies are an important piece of the puzzle in the diagnostic workup of cardiac neoplasms. This case report is the first description of the utilization of a laser lead extraction tool as a bioptome for intracardiac tumours. Two imaging modalities (echocardiogram, fluoroscopy), as well as the precise technique of the excimer laser, ensured safety for the patient. Clinical studies are paramount to further evaluate the laser sheath as a possible new instrument in the toolbox of an interventional cardiologist.
