A Bold New Era In Cardiovascular

Disease

We need bold new lectures.

•Lectures that go deeper, ie “Ahh….the benefit of hindsight”

•Modern speakers now stress EMOTION over CONTENT

•They tell us how they feel, not what they think!

SCRIPPS CLINIC

“Ahh….the benefit of hindsight”

Ideas for future lectures:

• Phew….that data smells awfully fishy to me

• Expletive deleted! My hospital administrators are killing

me

• Blah…another one of my papers got rejected

• Wow!...that was a great case

• Yuck!.....got burned by another stent thrombosis

• Ahhh….the benefit of foresight

• Since foresight only becomes apparent in hindsight,

you cant have foresight without hindsight.

SCRIPPS CLINIC

“Ahh….the benefit of

hindsight”

Mistakes:

• Inadequate response to the COURAGE trial

• Our erroneous referral of too many patients to bypass

surgery

• Mistakes I have made in the cath lab

• Mistakes I have made in my career and my life

“Benefit of hindsight” is really a

chance to talk about mistakes

SCRIPPS CLINIC

COURAGE trial results

should have been more

forcefully refuted

Mistake #1

• Criminal Homicide:

Murder first degree: Premeditation, intent

Murder Second degree: intent, no premeditation

Manslaughter 1st degree (voluntary manslaughter):

• Intent, heat of passion, a reasonable person is provoked to kill

Manslaughter 2nd degree (involuntary manslaughter or negligent homicide):

• No intent, but did not act with the care and caution of a reasonable person (ie kicking brick off bridge that hits someone below)

• Reckless homicide – aware of risk but does not care, ie driving recklessly at 90 MPH

Non-Criminal homicide

• Justifiable homicide – kill to protect yourself, police officer killing in the line of duty,

• Accidental homicide: A lawful act done under a reasonable belief that no harm is possible

Homicide: n. The killing of one person by another

COURAGE Myths

• „COURAGE trial patients were not low risk.‟

Diabetics 34%

Heart failure 5%

Multivessel disease 70%

• No, no, no…….this is high risk

....yada, yada, yada

Peterson and Rumsfeld, NEJM 359;7, 751-752 accompanying

COURAGE QOL manuscript in NEJM

SCRIPPS CLINIC

Courage Myths

• “Although the majority of patients who received optimal medical therapy alone had improved symptoms within 3 months, 21% crossed over and received PCI.” Actually, 32.6% of OMT patients crossed over to PCI

• “Thus, a very reasonable „take-home‟ message from the COURAGE trial is to pursue optimal medical therapy initially and if this is ineffective, turn to PCI” No mention of importance of angiography to risk stratify

1/3 patients will get an extra procedure

Courage Myths

Cost-Effectiveness of Percutatneous Coronary Intervention in Optimally

Treated Stable Coronary Patients

---Weintraub et al Circ Cardiovasc Qual Outcomes. 2008;1:12-30

Item PCI + medical Medical only PCI - Medical

Initial Cost $12,162 $752 $11,410

Lifetime Cost $99,820 $90,370 $9,451

But…the cost of diagnostic angiography was not included in the

medical only arm.

If the cost of the qualifying angiogram where included in the medical

arm, the cost differences would be mitigated.

Thus, the myth of COURAGE is perpetuated , i.e: “Angiography is not

required for patients with stable angina”

SCRIPPS CLINIC

How Has the COURAGE Trial Changed

My Practice?

LESSONS I HAVE LEARNED:

• You don‟t have to stent every little blockage in every

little vessel

• Fix the major, ischemia producing lesions

• Leave the small, distal, sidebranch vessels alone

unless the patient has recalcitraint angina

SCRIPPS CLINIC

Why such controversy? Are there two

different cardiologist phenotypes?

• We all agree medical therapy should be used in

most patients to reduce death and MI

Anti-thrombotics, lipid lowering, beta blockers and ACE

inhibitors

• We disagree about how to control angina. Here,

cardiologists have emotionally charged differences

of opinion:

Aggressive anti-anginal medications versus

revascularization

an oxygen molecule: O2

Revascularization Therapy For Angina:

Open the artery

Stents increase oxygen supply

Risk Factors for

Acceleration of Coronary Disease

• Smoking

• Hypertension

• LDL cholesterol

• Obesity

• Sedentery life style

• Bypass surgery

especially saphenous vein graft implantation

The most frequently implanted

surgical graft in the U.S. is still a

saphenous vein…

and after a few years, it‟s not a pretty

site!

SCRIPPS CLINIC

2006 Isolated CABG Data:

By 5 years, vein graft patency was less than 40%. It was even worse for radial

artery conduits and not much better for RIMAs!

----Khot UN et al. Cleveland Clinic, Circulation. 2004;109:2086-91.

Cumulative patency (<70% stenosis) by type of graft

A contemporary study (2002-2003), 73%

received statins, 90% received aspirin!

1,820 (81%) patients underwent 12 month angiography

By 12 months ¼ of SVG‟s are occluded; 40% of

patients had at least one occluded SVG

At 1 year ITA failure was less frequent than SVG failure 8% Vs 29%

Saphenous vein graft failure

+ Native disease acceleration

= A very difficult day for the

Interventional cardiologist!

Vein graft failure profoundly increased death, MI

and revascularization

Example: The Graft Dependent Patient

• The graft dependent patient was not graft dependent before surgery.

• He is graft dependent because of surgery

SCRIPPS CLINIC

Three Great Myths of Cardiac Surgery

• Myth # 1: “Cardiologists do not obtain informed consent

from patients prior to multivessel PCI.”

No surgical consultation obtained

Risk of restenosis not disclosed

• How many cardiac surgeons do you know who inform

patients that their saphenous vein graft only have about a

50% chance of patency within 5 years?

• How many cardiac surgeons do you know who inform

patients that their underlying native vessel disease will

accelerate due to SVG bypass, making their overall

coronary diseased burden much worse when the SVG

occludes?

• Myth # 2: Target vessel revascularization rates are much

higher following PCI compared to CABG

SCRIPPS CLINIC

Repeat Revascularization Following CABG:

Interpreting Clinical Trial Results

• Several years post CABG, both the native vessel and SVG often progress to a total occlusion or diffuse disease resulting in limited options for PCI.

• Given the high threshold for repeat bypass surgery (particularly in the presence of a patent LIMA graft), many post CABG patients are not offered repeat revascularization; not because they wouldn‟t benefit from re-intervention, but because the risks are prohibitive and the likelihood of success is low.

• Thus, much of the relative increase in repeat revascularization following PCI observed in clinical trials is because the post PCI patient, in contradistinction to the post CABG patient, remains a good candidate for further revascularization.

SCRIPPS CLINIC

What‟s missing from the PCI vs

CABG trial data discussion?

• Why does the debate seem to always focus on mortality

and repeat revascularization?

• Shouldn‟t we include morbidity endpoints?

• Myth # 3: Given differences in morbidity, bypass

surgery can even be compared to PCI.

If my PCI patient has a pseudo aneurysm requiring

surgical repair of the femoral artery, it is considered a

major complication that I have to defend at M&M and QA

committee. The untoward event is a small surgical

incision in the groin.

All CABG patients have a major surgical incision in the

chest. Therefore 100% of all CABG patients, by this

definition, suffer a major complication as a result of

their care plan.

Original Article

Drug-Eluting Stents vs. Coronary-Artery Bypass Grafting in Multivessel Coronary Disease

Edward L. Hannan, et al N Engl J Med, Volume 358(4):331-341 Jan 24, 2008

Mortality (after adjustment) 7.3% for DES Vs. 6.0% for CABG

This 1.3% absolute difference (p=0.03) yields a NNT of 77

If we need to do 77 bypasses to save one life, I believe the

mortality benefit is clinically meaningless!

This point was completely missed by the lay press

SCRIPPS CLINIC

The TVR Trade-off:

Good data – Bad interpretation

• The clinician‟s perspective

Most of my patients tell me they would rather go through 3, 4 or

even 5 PCI procedures rather than go through one bypass surgery

• Yet some are using SYNTAX data to say exactly the

opposite

Who would I send CABG Surgery?

Several restenoses, large territory at risk

Diabetics with diffuse disease, particularly if small vessels but usually these are poor targets for CABG

Total occlusions with large and important territory at risk, not amenable to PCI or failed PCI

Excessive proximal tortuosity, particularly if calcified with good distal targets

You Can Call Me Now…

• Bypass surgery is very hard to go through more than

once

– Your saphenous vein grafts will likely close down

– Your native vessels will likely shrivel up

– Your subsequent PCI will likely be more difficult

• But, PCI can be repeated as often as you like

– And you can always have a bypass

– Sometime in the future

– Or, maybe never

…Or You Can Call Me Later

Stranger Then Fiction

69 yo female, fell in bathtub and hit her head.

Went to ER, CT was obtained and something

“unusual” observed.

Due to stent procedure 8 years previously at

another hospital, patient referred to cardiology

for evaluation

Cine images of chest obtained

119

120

Lesson

Learned:

Always do a

“wire out”

shot

136

80 yo female, no

grafts, s/p double

barrel DES with

LAD in-stent

restensosis and

angina

137

Mid LAD Cypher ISR

Simple re-stent with

Taxus for Cypher

ISR

A humbling

experience

138

Re-stent with TAXUS

2.5 mm followed by

non-compliant 2.5

mm balloon @ 20 atm

139

Some “plaque shift”

into proximal LAD.

After “discussion”

decision to deploy

second stent

….hmmmm

140

Position second

2.5 mm stent

141

Deploy second

stent at 18 atm

142

!!!!!!!!!!!!!!!!!!!!!!!!!!!!

143

Tamponade with

stent delivery

balloon at 4 atm.

But….patient is

receiving AngioMax

Patient tolorates

inflation well, insert

IABP.

Need to wait 45 min

for AngioMax to

wear off

How to pass the

time?

144

145

Question 30

Which one of the following statements is true regarding echocardiography with

dobutamine administration in comparison with exercise echocardiography?

End of text

(A) Sensitivity and specificity are lower

(B) Oxygen demand is greater

(C) The incidence of procedural complications is lower

(D) It provides superior assessment of myocardial viability

(E) It is less desirable for assessment of risk prior to noncardiac surgery

146

Much improved.

Lets wait another 15

minutes.

147

Re-inflate balloon

for another 15

minutes

How should we

pass the time?

148

Question 31

In patients over age 60, which of the following characterizes cardiovascular risk for those

who have elevated systolic blood pressure, in comparison with those who have elevated

diastolic blood pressure?

End of text

(A) Lower

(B) Equivalent

(C) Higher

149

Question 36

A 60-year-old man is admitted to the hospital for treatment of atrial fibrillation,

associated with dyspnea and orthopnea, of two weeks' duration. He has had a heart

murmur for many years. Physical examination reveals pulse rate of 108 per minute

with irregularly irregular rhythm. Vital signs are otherwise normal. Cardiac examination

reveals a grade 3/6 holosystolic murmur at the apex and an S3 followed by a short

low-frequency murmur at the apex.

Electrocardiogram reveals atrial fibrillation. Chest radiograph shows moderate cardiac

enlargement and prominent vascular markings.

Therapy with digoxin, atenolol, furosemide, and potassium chloride results in marked

improvement of the patient's symptoms and slowing of the ventricular rate to 76 beats

per minute at rest. Doppler echocardiogram reveals nearly normal left ventricular

function, severe mitral regurgitation without evidence of mitral stenosis, and left atrial

dimension of 5.5 cm. Estimated left ventricular ejection fraction is 55%.

End of text

150

Which of the following is most appropriate at this time?

(A) Start warfarin therapy, and schedule semiannual evaluations including Doppler

echocardiography

(B) Start warfarin therapy, and perform direct-current cardioversion in three to four

weeks; then schedule semiannual evaluations including Doppler echocardiography

(C) Start heparin therapy, and schedule coronary angiography and mitral valve surgery

(D) Start heparin and warfarin therapy, and order transesophageal echocardiography; if

no clot is present, perform direct-current cardioversion; then schedule semiannual

evaluations including Doppler echocardiography

(E) Start warfarin and angiotensin-converting enzyme inhibitor therapy, and schedule

semiannual evaluations including Doppler echocardiography

151

After another 15

minutes of balloon

tamponade, (total

inflation time 1

hour) perforation

is a bit worse.

152

Remove IABP,

exchange for

second guide

catheter.

153

Deflate balloon for a

few seconds to allow

passage of second

guidewire

Then, reinflate

balloon!

154

Bring Jo-stent

through proximal

double barrel

stents down LAD

right up to inflated

balloon

155

Position 3.0 x 12 mm

Jo-stent across

perforation

156

Deploy Jo-stent @ 16

atm

157

Final result

Echo: minimal

pericardial effusion

ReoPro bolus plus

infusion

Discharge next

morning: no CPK

rise, no pericardial

effusion.

158

Emergency Angiogram for a 83 y.o Man Admitted

with Episodic Angina and Hypotension

The left main

coronary artery

has a 99%

stenosis, and is

intermittently

obstructing!

Patient requests

stents

159

Sudden Cardiac Arrest Due to Complete

Closure of Left Main Artery – CPR!

160

Emergency Balloon Inflation in Left Main Artery

161

A Little More Flow but CPR Continues

162

More Balloon Inflations

163

Better Flow but CPR Continues!

164

Now the Flow is Increasing and Cardiac

Contraction is Improving

165

More Balloon Inflations

166

Position Stent in Left Main Artery

167

Deploy Stent in Left Main Artery

168

Final Result – Normal Flow!
