This paper reviews Art Winfree's contributions to the bidomain model of cardiac tissue. Specifically, he first predicted quatrefoil reentry, he showed that an S1 refractory gradient is not required for an S2 stimulus to induce reentry, and his work on spiral wave meandering led to studies on how the path of the tip of a spiral wave is influenced by tissue anisotropy.

Recent publications have expressed the view that there is a shortage of cardiologists and it is growing worse. Both an increasing demand and a diminishing supply of cardiologists have been projected. An increase in the number of international medical graduates (IMGs) who enter cardiology practice has been proposed as a remedy for a projected shortage. The IMGs have to overcome challenges including clinical practice, language proficiency, and cultural differences before they are incorporated into the fabric of U.S. cardiology. With hard work, perseverance, excellence,compassionate care and support and mentoring, many have contributed to scientific and clinical cardiology in the U.S. Whether in the absence of a present crisis the projected shortage of cardiologists necessitates change in U.S. immigration policy is an open question.
