Median sternotomy is commonly used
for suture fixation of a myocardial lead. Instead of this conventional
technique, we used the technique of resecting the 5th costal
cartilage through a small horizontal skin incision at the left
5th sternocostal junction in 33 patients, between 1980 and 2001.
Here we describe this procedure, as well as the outcome of patients
who underwent this myocardial lead fixation procedure. A skin
incision of about 6 to 8 cm was made in the left 5th intercostal
space. Approximately 5 cm of the 5th costal cartilage was resected
through the skin incision. Then, a myocardial lead was sutured
on to the anterior wall of the right ventricle. The generator
was generally placed in the upper subcutaneous space of abdomen.
Additional costal cartilages were removed in 7 patients in whom
a larger operating field could not be obtained initially. The
electrode was sutured to the right ventricular wall in 28 patients,
right atrial wall in 6 patients, and the left ventricular wall
in 5 patients. The mean operation time was 150 min and mean bleeding
during operation was 82 ml. Long-term results (258 months at
the longest, at the time of writing) showed that all the patients
did well, except for one adult who suffered cerebral infarction,
and one child with pacing failure. Based on these findings, we
believe that this procedure is minimally invasive method, and
is good for fixation of a myocardial lead.
