A Brief History of Tau

1976, Tau was born in John Hopkins.
1992, the first non-invasive try, Harvard.
1992, the first formula, with four assumptions, Harvard.
1993, another non-invasive try with decent data, Mayo Clinic.
1995, a similar strategy applied to AI patients, Japan.
1995, I published a MR based formula with one assumption.
1997, the Harvard formula was validated in Cleveland.
2005, Langer presented a non-zero asymptote model.
2008, I improved my MR based formulas, without assumption.
2008, I did a similar deduction for AI based Tau.
2008, Chen developed program for my formulas, free download.
2008, my poster in ASE 19th Annual Scientific Sessions.
2009, my poster in CSE forum.
2009, DF guideline (ASE) recommended Harvard formula.
2009, I gave my opinion about the guideline recommendation.
2009, "Response to Bai" from guideline writing group. It motivated me to create this Blog.
2010, Dr Wang and me presented general Tau.
2011-11-29, I gave a talk in National Capital Echo Round (Ottawa)
2016-03-29, I gave a talk at the Heart Institute, the North Hospital (Shenyang, China)
2016-04-01, I gave a talk at the Cardiac Function Dept., the 1st Clinical College, Chinese University of Medicine. (Shenyang, China)
2016, Symmetry inspired by the approach of Tau.
2017, Calculation of LAP (based on my formulas) got a Chinese Natural Science Founding.

Tau and Beyond

Tau renders us a new approach to the cardiac function assessment. Since Tau is directly related to how powerful the muscle is at the beginning of diastole, it is well accepted as the best index to describe diastolic function.

For pragmatic clinical purposes, we recommend Tau measurement in patients with either MR or AI:

Keeping the classical Tau on mind; a universal Tau is becoming clearer and clearer on the horizon. All the formulas for universal Tau are here:

“The beauty of Nature lies in her simplicity.” Dr Quan Wang, a fellow of Royal Society of Canada applauded those formulas. 

Again, the universal Tau will reveal another secret, symmetry of cardiac function assessment
Applying it on four Doppler indexes, 17 new approaches came out of the shadow. Dr Sherif Nagueh told me those 17 new approaches might be very helpful, especially for RV and diastolic function assessment. 

We don’t know yet what will come next. Everyone is welcomed to try their luck in this new area.

So, it is safe to say Tau will revolutionize cardiac function assessment.

But, we have a lion in the way, the Harvard method of Tau measurement.
