I DO NOT have a financial conflict of interest in the context of this presentation.

Mavericks Created Modern Cardiology

Mavericks share 3 characteristics:Outside-the-box thinking, disdain for common wisdom, & persistence.

In a time of widespread challenge to conventional wisdom, One man challenges cardiologic teaching

MI mortality is 30% mostly due to CHFSwan challenges conventional Rx [strict bedrest x 3 weeks]His idea: treat aggressively, using bedside hemodynamicsBut CCU MD Danzig finds it impossible: catheter coils in RA

Our Story Begins With Brilliant IngenuityIn Response to Frustration

Genius is seeing what everyone else has seen and thinking what no one else has thought

Inspiration on Santa Monica Beach: sail a catheter into PACCU and cath lab MD’s ridicule idea of sails & wires

Danzig: Irreversible entanglement in chordaeMarcus: imagines it sailing “like a Mary Poppins umbrella”

Mavericks persist in the face of ridicule

Undaunted, Swan takes his idea to Edwards Laboratories’ engineers.

Edward’s engineers’ response to the idea ofa catheter festooned with sails and wires:

Page 7: Disclosure Statement of Financial Interest I DO NOT have a ... · I DO NOT have a financial conflict of interest in the context of this presentation. Disclosure Statement of Financial

It’s unanimous:

Putting Swan’s imagined catheter is a “logistic impossibility”Swan’s idea is dead.

But then…

Mind–Boggling Serendipity: Two Different Ideas CollideIn the Only Place in the World it Could Happen

By Now It’s 1969:Diamond & I Do Our First Animal Catheterization

Fluoroscopy: catheter has weaved thru entire right heart to distal PA!What should we do next?

Inserted thru jugular vein: Stuck in the coronary sinus??

Page 11: Disclosure Statement of Financial Interest I DO NOT have a ... · I DO NOT have a financial conflict of interest in the context of this presentation. Disclosure Statement of Financial

So we sterilize our catheter & go directly to our MIRU patient’s bedside

IRB’s don’t exist

Our First-Ever Catheterization In Man:Horrifying Run of Ventricular Tachycardia

Spectacular good luck allows us to eliminate catheter-tip induced tachycardia

Induced by the catheter tip flailing wildly within the RV

Double-lumen Cath Overturns Conventional ThinkingAnd Reveals Things We Never Knew

•The gold standard, CVP, has little value for assessing left heart failure•PCW changes hours, often a day, before rales or chest xray•We discover new entities like RVMI and silent mitral insufficiency

Yet for CHF management, we also want to measure cardiac output. Now enters the incredible benevolence of chance.

The Incredible Benevolence of Chance: It Comes Not from Medicine, But from Politics

Abandons all his worldly possessions to escape communism49 yo unknown lab researcher [9 ms]; prospects bleakThru Jewish philanthropy he lands at Cedars animal labHe’s penniless, but what he brings is beyond imagining

In Prague Willie has invented thermodilution cardiac output.He injects a cold solution in RA, & records temperature change in the PAWith just 2 thermistor wires, we can add CO measurement to our catheter!

As Swan contemplates sailboats, a world away in Prague, Willie Ganz…

But then…

Page 16: Disclosure Statement of Financial Interest I DO NOT have a ... · I DO NOT have a financial conflict of interest in the context of this presentation. Disclosure Statement of Financial

Disaster! It’s impossible to pass the thermistor wire to the RA

The Impossible ProblemThermistor wire either buckles or obstructs flow to RAInjectate temperature is not knowable; CO cannot be measuredWillie’s dream is shattered

Predict RA injectate temp by measuring: injectate temp outside the bodycatheter length patient’s body temperature

We bench test, then validate vs cardiogreen in cath labEdwards incorporates PA thermistor into body of catheter

Here's to the mavericks,the misfits, the round pegs in the square hollesThey're not fond of rules, and they have no respect for common wisdomYou can glorify or vilify them, but you can't ignore them because they change things. And while some may see them as the crazy ones, we see genius, Because the people who are crazy enough to think that they can change the world…

are the ones who do.
