Disclosures

• Speaker/consultant- Atricure

• Speaker- Boston Scientific, Medtronic, Biotronik

Building a Hybrid program

• Collaboration between EP

and CTS in not the norm

• Clear advantages for

physicians, patients,

hospitals

• Requires concerted effort

and teamwork

Building a Hybrid program

•Barriers to progress

–Surgeon

–Administration

•First Steps (Clinic)

• Illustrative Cases

EP Perspective

Interventional EP begain in the operating room

The electrophysiologist is the natural predator of the cardiac surgeon

Fellowship Lessions:

Call the surgeon only when you need to be “bailed out”

Progress

Collaboration is additive: volumes, outcomes (CRT, AF, Extraction, VT), innovation

EP Perspective- Barriers

• Extends EP toolset (limitations)

• Critical to Sustain an Extraction Program

• Completes AF Program

• Durable PVI, posterior box

• GP Ablation

• LAA isolation/closure

• CAB/Valve +Maze

• CRT, VT

EP Perspective- Advantages

Surgical Perspective- Barriers

• Time

• Comfort zone

• Training

• EP endpoints

• Communication

and EP

feedback

“Check the Ego at the door”-Steve Hoff, MD

• Case Mix and Volume

• Better understanding of arrhythmia mgmt

• Wider application of AF therapies to CAB/AVR

• Feedback and validation of surgical ablation

• Veins, box, LAA, outcomes

• Close working relationship improve EP

consultative service

• Post procedure management and follow-up

• Not “bail me out”

Surgical Perspective- Advantages

Hospital Perspective

• Model already exits (Lung Cancer, Heart

Transplant, TAVR)

• Improved quality, outcomes

• Right intervention at the right time

• Patient experience

• Widen referral network

• Procedural volume with halo effect

• Improved utilization of shared spaces (hybrid labs)

• Case example failed LV lead implant

Getting Started at Vanderbilt

AF Clinic• EP

• Arrhythmia Surgeon

• EP NP

• Device Clinic

• Shared Space

• Comprehensive service for AF patient

• One stop shop from warfarin to hybrid ablation

Lead Extraction- Patient Selection

• Collaboration required lead extraction program

• Active Process

• Size of the vegetation

• Left sided endocarditis

• Dwell time of the leads

• Lead Design

• Structural/Congenital Heart Disease

Case #1 Extraction

• 55 year old with ICM and

primary prevention ICD

• Device ERI

• Riata with exposed

conductors and visible

thrombus

• Normal parameters

• No suggestion of SBE

• On OAC x 2 months with

no change

Case #1 Extraction

Case #0 Extraction

Case #1 Extraction

• Planned hybrid extraction

• Lead liberated with laser

down to SVC/RA junction

• Fem/fem bypass

• Right mini-thoracotomy and

lead removal

• New lead implant and

generator change

Hybrid AF: Lesion Set

Lesions mimic Cox-Maze III.

Initial experience was for same day hybrid (n=33).

Can be performed staged.

LAA ligation evolved from GIA staples to Atriclip.

N Contact pericardioscopichybrid ablation (separate data).

Case #3

• 52 y/o with h/o NICM s/p ICD

• Cardiac arrest in Germany in 2006

• Had 2 EP studies and extensive work-up in one

of the most reputed Heart Hospitals in Texas.

Inability to achieve clinical success. ICD

placement for decreased EF.

• Referred to for ICD @ ERI. Continues to have

frequent symptomatic PVCs and reduced EF

despite medical therapy

Clinical PVC

RF in LCC

Surgical Approach

• Median sternotomy off-pump as patient was a

Jehovah’s Witnes

• Exposure of left main, LAD, left circumflex, and

AIV from epicardial fat.

• Bipolar RF lesions were delivered under the

displaced cardiac vasculature using an Atricure

cool rail

• Subsequent point RF lesions were delivered

with an Atricure pen device

ICD interrogation

• 66 year-old male with coronary artery disease

with prior inferior myocardial

• infarction (4-vessel CABG and MVR in 1993)

• Pt was transferred in the setting of VT storm.

• Previous endocardial study with identification of

an epicardial VT originating from the inferior

wall of the left ventricle(LV).

• Chronically occluded RCA and SVG to PDA

Case #4-Ventricular Tachycardia

Ventricular Tachycardia- Access

• Repeat endo and epi

mapping with surgical

subxiphoid access

• Blunt dissection of

adhesions to expose the

inferior LV wall to the

mitral annulus

• Ablation with EpiSense

surgical ablation catheter

(nContact)

• Energy was delivered to a

broad region in the inferior

wall substrate with repeat

mapping revealing signal

attenuation and

homogenization of scar in

this region

• One ICD therapy in 3 years

in setting of hypokalemia

(PMVT)

• Interventional EP began in the operating room

(nothing new under the sun)

• Training an EP surgeon requires work and

effort (just like training fellows)

• Access to the surgical tool set expands what

we can offer to our patients in multiple areas

(CRT, AF, Extraction, VT)

• Collaboration between EP and CTS will

facilitate more progress than we can

accomplish individually
