Background: Cardiac angiosarcomas are an extremely rare tumor with an incidence of only 0.056%. Diagnosing this rare tumor becomes even more difficult as the presentation of cardiac angiosarcomas varies based on anatomic location. Depending on the tumor's proximity to valves, symptoms may be more consistent with heart failure, while growth throughout the conduction system may produce arrhythmias.
Case Report: We present the case of a young male with a significant tumor burden of cardiac angiosarcoma in his lungs whose symptoms included pleuritic chest pain and hemoptysis. This patient did not have the classic finding of right-sided heart failure; instead, his presenting complaint was hemoptysis.
Conclusion: The diagnostician's differential diagnosis must be broad when encountering common chief complaints, such as hemoptysis and chest pain.

As multiple imaging modalities cannot reliably diagnose cardiac tumors, the molecular approach offers alternative ways to detect rare ones. One such molecular approach is CRISPR-based diagnostics (CRISPR-Dx). CRISPR-Dx enables visual readout, portable diagnostics, and rapid and multiplex detection of nucleic acids such as microRNA (miRNA).

Cardiac angiosarcoma is a rare, diagnostically elusive disease with a poor prognosis. Herein, we describe the case of a 61-year-old man who presented with cardiac tamponade caused by perforation of the right atrial wall resulting from an invasive angiosarcoma. The tumour, which had spread throughout the entire right atrial free wall, was resected under cardiopulmonary bypass.

Primary cardiac angiosarcomas are rare malignant tumors that can cause chest pain and heart failure symptoms. They can be diagnosed using multimodality imaging, primarily echocardiogram, with formal diagnosis requiring biopsy. A 56-year-old man with history of hypertension and dyslipidemia presented with acute crushing chest pain and shortness of breath.

Background: Cardiac angiosarcomas are exceptionally uncommon, and result in significant morbidity and mortality. Utilizing a multimodality approach enhances the characterization of the mass for optimal diagnostic outcomes. The recommended primary treatment involves complete surgical resection coupled with adjuvant radiochemotherapy.

Background: Primary cardiac angiosarcoma (PCAS) is a rare and aggressive heart tumour with limited treatment options and a poor prognosis. Understanding cellular heterogeneity and tumour microenvironment (TME) is crucial for the development of effective therapies. Here, we investigated the intratumoural heterogeneity and TME diversity of PCAS using single-cell RNA sequencing (scRNA-seq).
