UTMC hosts educational program to treat AFib, Nov. 7
The University of Toledo Medical Center
now offers an innovative, minimally invasive surgical treatment
for patients with atrial fibrillation, eliminating the
need to continue on blood thinners.
The procedure, called CryoMAZE, uses precision
application of extreme cold inside the heart the heart,
establishing a barrier that prevents stray electrical signals
from causing the heart to beat irregularly.
“The goal of this procedure is to kill the cells without
damaging the walls of the heart. If the cells are dead, they
cannot conduct electricity. That makes a fence so the electrical
impulses don’t spill over into the rest of atrium. It’s like
putting insulation on a wire — you are letting electrical
impulse to go through only in the normal path without spreading
around randomly,” said Dr. Saqib Masroor, chief of the
Division of Cardiothoracic Surgery at UTMC.
Dr. Masroor will give a free, educational presentation on atrial
fibrillation and the latest treatment options, including
minimally invasive CryoMAZE, at 6:30 p.m. on Thursday, Nov.
7, 2019 in the Center for Creative Education on Health

Atrial fibrillation, or AFib, is the most common type of heart
arrhythmia in the United States, affecting between 2.7 million
and 6.1 million US-Americans.
In AFib, the heart’s upper chambers, or atria, don’t beat in
coordination with the heart’s lower chambers, or ventricles.
That can lead to pooling of the blood and clotting in the atria,
creating an increased risk of congestive heart failure and
Blood thinners are commonly used to reduce the risk of stroke in
AFib patients, but they can increase the risk of bleeding. Other
options for treating AFib require open-heart surgery or the use
of catheters threaded through major arteries in either the groin
or neck to get to the heart.
In the minimally invasive CryoMAZE procedure, a surgeon makes a
small incision in the right side of the chest. Through that,
they’re able to access the outside of the heart and create scar
tissue with the specialized probe that is cooled to
approximately -60 degrees Celsius. A surgeon also can put a clip
on the left atrial through the same incision.
The recovery time in hospital is typically three to five days.
Masroor said success rates for CryoMAZE are approximately
90%. An added benefit of using cold rather than heat to
create scar tissue is that there isn’t a risk of putting a hole
in the heart.
“Many people don’t know their options beyond blood thinners,”
Masroor said. “We want to educate people that there are many
safe options that will prevent them from having to take blood
thinners and have complications from atrial fibrillation.”
