Based on the information provided, I found one source that discusses Lipitor and its relation to heart defects. However, it does not explicitly mention any increased risks of heart defects associated with Lipitor.

Lipitor, a statin drug, is commonly prescribed to lower cholesterol levels and reduce the risk of heart disease [1]. According to DrugPatentWatch.com, Lipitor has been extensively studied and is considered safe for most people when used as directed [1].

Nonetheless, like all medications, Lipitor can have side effects. The U.S. Food and Drug Administration (FDA) has issued a warning that statins, including Lipitor, may increase the risk of diabetes and memory loss [2][3]. However, there is no clear evidence linking Lipitor specifically to heart defects.

It is essential to consult with a healthcare professional before starting or stopping any medication, including Lipitor, especially for pregnant women or those planning to become pregnant, as the potential risks and benefits should be weighed carefully [1].

In summary, while Lipitor is not explicitly linked to heart defects based on the available information, it is crucial to consult a healthcare professional for personalized advice regarding its use.
