AF ablasyonu=PVİ • Pulmoner ven izolasyonu AF ablasyonunun temel taşıdır.

• Hedef PV ile LA’nın elektriksel izolasyonudur.

Paroksismal AF’da CRYO

• RF ile benzer başarı oranları

• Avantaj – Nispeten kolay, son-noktası basit, öğrenim eğrisi dik

– Tek transseptal ponksiyon

– Daha kısa işlem ve LA süresi

– Majör komplikasyon oranları daha az

CRYO ile AF

ablasyonunun limitasyonları

• Anatomik kısıtlılıklar • PV ostiumu dar veya çok geniş

• PV ostiumu açılı

• PV varyasyonları: Aksesuvar PV, Common os

• Voltaj ve aktivasyon mapping yapılamaması

• PV antrumu dışında ablasyon kısıtlıdır • Lineer ablasyon, CFAE ablasyonu , non-PV tetikleyicilerin ablasyonu, fokal impulse ve

rotor modulasyonu (FIRM), sağ atriyal ablasyon yapılamaması

• Nüks vakalarda farklı bir ablasyon metodolojisine

imkan vermemesi

In Arctic Front Cryoballoon, the most

concentrated cooling zone occurs near the equator

of the balloon. Aligning the balloon coaxially with

the PV may be an important factor, but may be

difficult in some vein anatomies.

Arctic Front Advance Cryoballoon with

EvenCool Cryo Technology is designed to allow

more flexibility in balloon positioning to ablate

the PVs.

FIRE AND ICE

Some say the world will end in fire,

Some say in ice.

From what I’ve tasted of desire

I hold with those who favor fire.

But if it had to perish twice,

I think I know enough of hate

To say that for destruction ice

Is also great

And would suffice.

• An agitation device designed to “stir” the fluid within the balloon to achieve a uniform temperature at the tissue interface, and a RF generator with a maximum output of 200 W. • The balloon can be inflated to 25–35 mm in diameter using an ionized contrast medium diluted 1:1 with physiologic saline. • RF is delivered between the coil electrode inside the balloon and the 4 cutaneous electrode patches placed on the patient’s back. • Tissue is heated thermally at the interface to the balloon membrane, and that thermal transfer is the primary mechanism for ablation, not RF current flow.
