A Moment in History

William S. Halsted, MD

William S. Halsted, MD
(1852 – 1922)

American anatomist, teacher, and surgeon, William Stewart Halsted was born in New York City, USA to a wealthy family of English origin. His father was involved in charitable work and Governor and trustee to a city hospital. Not a brilliant student initially, Halsted took an undergraduate in Liberal Arts in Yale, CT., after which he entered the Medical College of Physicians at the Columbia College, where he excelled.

As a second-year medical student Halsted applied and obtained a position in surgery at a local hospital. In here he learned about Lister’s antiseptic technique and became an adamant proponent of it to reduce infection. In 1877 Halsted obtained his MD. After a short time as House Physician at the New York Hospital, Halsted traveled to Europe to further his education studying for two years at the Universities of Vienna, Leipzig, and W?rzburg.

Besides being at the forefront of surgical and antiseptic techniques (introducing the use of rubber gloves in surgery), Halsted was extremely concerned with the way medical students were taught in the US. He pioneered bedside clinical round discussions with the medical students after two years of basic sciences studies. Halsted developed the idea of a patient chart; he also developed the residency program for medical students in use today.

Halsted is probably the most influential researcher and surgeon at the turn of the century. He dedicated time to the study of intestinal anastomoses and the use of silk as a suture material. His experimental work in 1887 proved that the inclusion of the submucosa layer in an anastomosis was mandatory, as well that a single layered anastomosis was enough to attain closure. Perhaps Halsted’s most important contribution was the application and use of the scientific method to surgical questions. Halsted’s principles set the standards used today in surgical suturing and surgical stapling.

He also pioneered the development and surgical techniques for radical mastectomy as a treatment for breast cancer.

As a side effect of this studied in anesthesia and the use of cocaine for anesthesia, Halsted became addicted to this substance, a problem that followed him through the years. Without impairing his capacity as a researcher and a surgeon, Halsted eventually recovered. He died in Baltimore in 1922 as a complication to surgery.

If you arrived to this website looking for information on Atrial Fibrillation, you will find some here and in this article.


Dr. Randall Wolf

Prevention of Stroke in Atrial Fibrillation;
Elimination of the Left Atrial Appendage.
An online educational video.

Randall, K. Wolf MD, FACS, FACC


This video educational program is hosted by the Houston Methodist DeBakey Heart and Vascular Center Education Center

Atrial fibrillation (AFib) is estimated to affect up to 4% of the population. Characterized by a rapid, irregular heartbeat, AFib is largely due to abnormal electrical impulses that cause the atria of the heart to quiver instead of beating steadily. Blood flow is reduced and is not completely pumped out of the two small upper chambers of the heart, the atria. This negatively impacts cardiac performance and also allows the blood to pool and potentially clot, especially in an extension of the left atrium, the left atrial appendage (LAA). At rest, a normal heart rate is approximately 60 – 100 beats per minute. In a person with AFib, that heart rate can increase to 180 bpm or even higher.

The main concern with AFib and stagnant blood flow in the LAA is the potential for clot formation (thrombus). While this can happen in either atria (right or left) the anatomy of the right atrium and right atrial appendage are less conducive to clot formation. The LAA is exactly the opposite and the clots, should they float into the bloodstream, tend to enter the larger arteries that go towards the head and brain, increasing the chances for a stroke.

In this educational video Dr. Wolf discusses the above, as well as the benefits of the elimination of the LAA, decreasing blood pressure, decreasing the chances of a stroke, and helping return the heart to normal rhythm.

Dr. Wolf is a surgical innovator who since the year 2000 has been a pioneer in the minimally invasive surgical treatment of AFib. He has performed over 2000 Wolf MiniMaze procedures since the first one in 2003 and has demonstrated the procedure to over 800 heart surgeons worldwide. He has been visiting professor in 18 countries, including Oxford University, University of Tokyo and Peking University. Dr. Wolf has delivered hundreds of invited lectures at hospitals, academic meetings and seminars in the United States and abroad.

Dr. Wolf is currently a member of the DeBakey Heart and Vascular Center at Houston Methodist Hospital in the Texas Medical Center. He serves as the arrhythmia specialist of the group. In 2018 Dr. Wolf operated on AF patients from 32 US states. He was also the keynote speaker at the annual Japanese Society for Tobacco Control in Takamatsu, Japan and the annual Chinese Society of Cardiothoracic Surgeons in Shenyang, China.
