When
performing TMR with a low powered Holmium:YAG laser, a qualified
cardiac surgeon delivers precise laser energy directly to the target
area(s) of the heart muscle. When performed as a sole therapy, it is
done through a small incision between the ribs (thoracotomy) with the
patient under general anesthesia. TMR can also be performed as a
complement to bypass surgery in patients that have diseased areas of
the heart that cannot be bypassed. The precise laser energy is
delivered to create small channels into the heart chamber. During a
typical procedure, approximately 20 - 45 channels are made in the heart
muscle.
The channels in the heart muscle seal over immediately with little
blood loss while the new channels allow fresh blood to perfuse the
heart wall immediately. According to research and clinical studies,
these channels promote growth microvascularization, or angiogenesis,
over time. That, in turn, may provide damaged heart tissue with a
better supply of blood and oxygen. Angina symptoms, including chest
pain, usually subsides over time in the majority of patients treated
with TMR.
What to expect following the procedure.
The
follow-up requirements for recovery after a TMR procedure are similar
to those following other heart surgeries, including regular check-ups
by your physician. Your physician will advise you when you may expect
to return to more normal activities.
