Patient data
From January 2005 to May 2017, 439 patients underwent MV surgery at our
department. A MIVT procedure was done in 250 patients between July 2008
and May 2017, and 189 patients were operated through conventional
sternotomy between January 2005 and December 2014. Pre-, intra- and
postoperative data were retrospectively retrieved from the patient’s
medical records. Organ-specific biomarkers were obtained preoperatively
and per 24 hour on ICU concerning assessment of liver, kidney and
myocardial damage, while lung and brain function were based on clinical
parameters such as ventilation time and stroke incidence respectively.
Evaluation of systemic inflammatory response was based on CRP values,
obtained preoperatively and at the first and second day after surgery.
Use of blood products, postoperative blood loss and hematological
assessment were additionally included.
The clinical follow-up ended in November 2017, considering the endpoints
survival, reoperation free-survival and late MV function.
