Nocardia infection can disseminate to any organ system of the body but the pulmonary system is the most commonly involved system. In some rare cases, the heart can also be involved and the resulting cardiac mycetoma can be treated successfully with antimicrobials without the need of surgery, unlike fungal cardiac mycetomas wherein surgery may be required in addition to antimicrobial therapy. We present an interesting case of post-renal transplant cardiac nocardiosis, which was treated successfully with a course of antibiotics.
