We are starting a series of articles focusing on the rhythm control system of the heart, the cardiac conduction system, ganglionated plexi, and the pioneers that have led to this moment in cardiac history. Follow the links on each article for more information.

A dive into the anatomy and function of the left atrial appendage (LAA) and how the anatomy sets the stage for the formation of clots in the presence of atrial fibrillation. These clots, left unattended, can cause a stroke. The article also explains why LAA occluding devices, while reducing the potential for a stroke, are not a solution for atrial fibrillation.

Continuing the history of the discovery of the conduction system of the heart. Sunao Tawara discovered many of its components, joining Keith, Flack, His, and Purkinje. https://www.clinicalanatomy.com/mtd/367-sunao-tawara-m-d

Another "Moment in History" showcasing Paolo Mascagni. He published the largest (by page size) human anatomy book ever! Each page is 40 by 30 inches in what is known as "double elephant folio". A large portion of what we know today about the lymphatic system we owe to Mascagni. Hope you enjoy the article as much as I have following the works of Mascagni trough the years.

Happy New Year 2026!! This year I intend to continue posting articles on anatomy, physiology, and medical history. Today we revisit Bachmann's bundle (BB), a cardiac structure that is critical on the right-to-left almost simultaneous atrial activation. Natural and iatrogenic damage to BB cause atrial dyssynchrony and altered cardiac rhythm leading to potential atrial fibrillation and the possibility of stroke even in sinus rhythm.

Another post of a cardiovascular "Moment in History". In this case we present Jean George Bachmann (1877 - 1959), who in 1916 described the function of a structure we know today as "Bachmann's bundle", an important interatrial conduction structure whose failure can lead to cardiac arrythmia, including atrial fibrillation.

This topic has been on my mind for months. The amount of wrong, uninformed anatomical and surgical AI generated text, images, video, and audio in social media is staggering. Add to this the plagiarism of books and other scholarly media, and we have a growing problem in our hands. This problem is slowly creeping into education in our industries, divulging information that is not correct. https://www.linkedin.com/feed/update/urn:li:activity:7381028452205879298/

The most common anatomical variation in thoracic anatomy is the persistent left superior vena cava (SVC). There is only one SVC in the right side of the thorax, but many of us have TWO!! one right and one left! Fact is, many people go through life not knowing of this condition, which is usually asymptomatic.

La variación anatómica mas común es una vena cava superior (VCS) izquierda persistente. Normalmente tenemos una sola VCS, en el lado derecho del tórax, pero muchos tiene DOS VCS!! una derecha y una izquierda. De hecho, muchos pasan toda su vida sin saber de esta condicion, que es usualmente asintomática.

An interesting article on an anatomical variation that is normal in pigs, but not in humans!

The tracheal bronchus is a known anatomical variation first described in 1785 by Eduard Sandifort (1742 – 1814), a Dutch physician and anatomist. Sandifort was the first to describe in detail what we know today as the Tetralogy of Fallot, although Nicolaus Steno (1638-1686) mentions the components...

A few weeks ago, I came across a very interesting article in Spanish by Dr. Jose Manuel Revuelta, a cardiovascular surgeon from the University of Cantabria, Spain. The article talked about the “small brain inside the heart”. This concept is not new, but the article touches on new research on the heart's intrinsic and autonomous neurovegetative system. Dr. Revuelta has graciously granted us permission to translate and publish his article.
