Hemodynamic Changes in Off-pump Coronary Artery Bypass Grafting
The purpose of this study is to study the positioning and stabilization of different cardiac walls performed during off-pump coronary artery bypass grafting (CABG) may have dissimilar impact on hemodynamics.
The objective is to evaluate hemodynamics during distal coronary anastomoses in different cardiac walls.
Coronary Artery Disease
|Study Design:||Observational Model: Cohort
Time Perspective: Cross-Sectional
|Official Title:||Hemodynamic Changes in Off-pump Coronary Artery Bypass Grafting|
Patients with coronary artery disease undergoing elective off-pump CABG
- Twenty patients undergoing off-pump CABG monitored with pulmonary artery catheter and esophageal doppler will be enrolled.
- Patients with a left ventricular ejection fraction <50%, age >80 yr, creatinine >1.4 mg/dl, reoperation, valvular heart disease or chronic obstructive pulmonary disease were excluded
- Data will be collected after volemic and hemodynamic adjustments, after heart positioning and establishment of a suction stabilizer and before its removal in anterior, lateral or posterior wall artery anastomosis.
- Data was compared by means of two-way repeated measures ANOVA.
