St. Jude Medical is seeking the retraction of an article by Robert Hauser in Heart Rhythm linking the company’s Riata and Riata ST leads to 20 or more deaths. In a press release (see below) issued on Friday afternoon, St. Jude alleges numerous mistakes and oversights in the Hauser paper. In a brief statement to CardioBrief, Hauser wrote: “We stand by the conclusion of our study, namely: “Riata and Riata ST ICD leads appear prone to high-voltage failures that have resulted in multiple deaths.”
