Abstract: Disclosed are methods of preventing or treating cardiac arrhythmia. In one embodiment, the methods include administering to an amount of at least one polynucleotide that modulates an electrical property of the heart. The methods have a wide variety of important uses including treating cardiac arrhythmia.

Abstract: Application of a virus with poloxamer alone onto atria results in diffuse epicardial gene transfer with negligible penetration into the myocardium. Progressive increases in protease concentration, however, allow transmural gene transfer. After protease exposure, echocardiographic left atrial diameter does not change. Left atrial ejection fraction decreases on post-operative day 3, but returns to baseline by day 7. At appropriate protease concentrations, tissue tensile strength is unaffected by the procedure. Transmural atrial gene transfer can be effected using this direct “painting” method.

Abstract: The present provides methods and compositions that enable effective delivery of nucleic acids to desired cells, including to a solid organ such as a mammalian heart. The methods and compositions enable effective gene transfer and subsequent expression to a majority of cells throughout a solid organ such as the heart. Methods and compositions of the invention preferably provide enhanced vascular permeability that enables increased gene transfer to targeted cells, but without significant degradation or injury to endothelial cell layers. Global delivery of nucleic acid to an intact heart has been achieved with as little as 2 minutes of intracoronary exposure to the administered nucleic acid.
