Sterile Abscess in the Myocardium after Direct Intramyocardial Injection Related to Gene Therapy in a Swine Model

<table>Cross-section of the heart at the papillary muscle level. The heart was stained by TTC to distinguish the infarct tissue from the normal myocardium. Intramyocardial abscess was detected inside of the infarct tissue. TTC = triphenyltetrazolium chloride.</table>
