Left ventricular intimal sarcoma: a case report.

Background: Secondary cardiac tumours are much more common compared with primary (100-1000 times). The majority of the primary cardiac tumours are benign; however, almost a quarter are malignant, and 95% of these are sarcomas. The rarest type of primary malignant cardiac sarcoma is intimal (spindle cell) sarcoma.

Left ventricular perforation from a dislodged needle migrating via a pulmonary artery branch in an intravenous drug user.

Embolised needles causing injury to the right heart and cardiac tamponade has been reported before in intravenous drug users, but to our knowledge, this is the first reported case of a needle migrating via the pulmonary arterial system to cause perforation of the ventricle. Appropriate utilisation of imaging modalities such as plain X-ray and point-of-care focused cardiac ultrasound can be vital and life-saving in the emergency setting, and the value of gated multidetector CT as a powerful tool for imaging moving structures is highlighted.
