AF ablation is a waste of time and money • Dr Dhiraj Gupta MRCP MD DM • Liverpool Heart and Chest Hospital
AF ablation is a waste of time and money:(you must be joking!) • Dr Dhiraj Gupta MRCP MD DM • Liverpool Heart and Chest Hospital
AF costs megabucks…. 2.4% of the total NHS budget
Conventional treatments limited efficacy Drugs only work in 1 in 3 patients
Not only are drugs potentially ineffective but….. • They often cause unacceptable side effects • Discontinuation rates due to Adverse Effects: • CTAF: 18% Amio, 11% Sotalol • AFFIRM: 12% Amio, 11% Sotalol, 28% Flecainide • They may increase mortality • SPAF: esp. in heart failure • AFFIRM: AAD associated with mortality (p=0.0005)
Dronedarone isn’t the answer…. • Mild antiarrhythmic action • AF recurrence at 1 year: 64% vs 75% for Placebo • << Amiodarone (free from AF at 6 mo: 37% vs 58%) • Increased mortality in Heart Failure (ANDROMEDA) • Only approved by the NICE with reservations
Finally, a cure is in sight!...... Culprit: triggers in pulmonary veins
The procedure works….. Current success rates 80%
AF ablation has evolved rapidly… • Success rates have doubled • Paroxysmal AF: 40-50% to 80-90% • Persistent AF: 30-40% to 70-80% • Procedure times have halved • From 4-6 hours to 2-3 hours • Complication rates have halved: 4% to 2%
Drugs 30% efficacy Life long suffering Ablation 80% chance of cure One-stop solution
If you always do what you always did…you’ll always get what you’ve always got
Yes, AF ablation costs money… • 100,000 AF cases a year Median 1.5 procedures • £4000 per ablation • Total cost: half a billion pounds
But where would you rather spend this money? • ? Iraq War: £ 4.5 billion (Mar 2006) • ? Olympics: £9.8 billion • ? NHS IT project: £15 billion • ? Bank Bailout £850 billion
Upfront costs outweighed by subsequent savings… • Costs of recurrent hospital admissions • Electrical cardioversions • Absences from work • Costs of lifelong drug therapy • Regular INR tests • Decreased risk of the serious AF sequalae • Stroke • Heart Failure
Measures to make ablation more cost effective 1. Careful patient selection: ablation not offered • Very long standing Persistent AF (>3 years) • Very large LA (>5.5 cm) • Morbid Obesity (BMI >40) • Age >80 years • Significant co-morbidity
Measures to make ablation more cost effective 2. Individualised ablation strategy: Improve single procedure success rates Accepted for oral presentation at Cardiostim, Nice June 16-18, 2010
Finally... What would you want?!
