Beating heart mitral valve replacement with retrograde coronary sinus perfusion technique.

AIM

The aim of this study was to assess the efficacy and applicability of on-pump beating heart mitral valve replacement with Sorin Bicarbon prosthesis using retrograde coronary sinus perfusion.

METHODS

The prospective study included 17 consecutive patients who underwent mitral valve replacement with Sorin Bicarbon prosthesis using retrograde coronary sinus perfusion. The operative variables and early outcome of this procedure are presented.

RESULTS

Retrograde coronary sinus perfusion and venting the heart from the aorta and from the pulmonary vein provided good visualization of the operative field and performance of the operations without any difficulty. Partial oxygen pressures of coronary sinus perfusion blood and the returning blood from the coronary ostia were 299.7+/-30.7 and 37.6+/-6.2 mmHg respectively. Postoperative peak creatine kinase-MB and troponin T values were 58+/-28.5 IU/L and 1.5+/-0.4 ng/mL, respectively. No mortality or major complication was observed and all the patients were discharged from the hospital in good condition.

CONCLUSIONS

On-pump beating heart mitral valve replacement with Sorin Bicarbon is a good surgical option, and it has the advantage of maintaining physiologic condition of the heart throughout the procedure.
