When was the first angiogram performed

Although doctors in the s regularly used dye to view the valves and chambers of a person's heart, fear of killing their patients kept them from even attempting to visualize the smaller vessels. Without a clear view of the coronary arteries, cardiologists couldn't assess a person's heart attack risk or intervene if the vessels were partially or completely blocked.

But as soon as Sones discovered that dye could be safely inserted into the coronary arteries, he began developing the technique of modern angiography, which lets cardiologists see and fix clogged arteries in the heart.

Sones' accident marked a huge step forward for cardiac imaging, but the event itself was far from serene. On the morning of Oct. It is named after Dr. Sven-Ivar Seldinger , a Swedish radiologist who introduced the procedure. Mason Sones is credited with the discovery of injecting contrast dye into a large blood vessel after accidently injecting radiocontrast in a coronary artery instead of the left ventricle. He enhanced the procedure and is credited alongside Shirey for the development.

Many improvements to the process allowed for quicker examinations with improved results, which allowed for the procedure to be more commonly used. Forssmann forced the tube farther, resisting at one point the overwhelming urge to cough when the tube collided against his vein. When the tube was shown to be in the right auricle Dr. Forssmann had the technician snap the picture, finally obtaining the proof that he needed. Forssmann uneventfully removed the tube. The real incident involved in this daring experiment was to come: Dr.

Forssmann had to face the reactions—not only of his mentor Dr. Schneider, but also the medical community. The majority was ostensibly displeased with his methods, rationale, and approach, believing them too dangerous.

After repeated self-experiments, Dr. Forssmann learned that his self-cath procedure could be safely performed; he submitted his findings with fluoroscopic proof to the German medical community at large. At least one prior researcher, the surgeon Ernst Unger, repudiated Dr. Despite the rising tide of opposition to his findings, Dr.

Forssmann pushed on. His subsequent experiments with rabbits and dogs and ultimately himself proved that catheterization angiography could not be achieved with simply sodium iodide.

He developed the use of groin catheterization to reach the inferior vena cava through the femoral veins. By this time, he had decided to stop his self-experimentation, having reached his limits with exploration. These are some of the innovations that will enhance healing and….
