Direct observation of the effect of mitral valvuloplasty on beating heart / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To summarize the method and experience of direct observation of the effect of mitral valvuloplasty on beating heart.@*METHODS@#Twelve patients with mitral regurgitation underwent mitral valvuloplasty. When the heart was beating slowly before releasing the aorta, the morphology and function of the mitral valve were evaluated by direct observation. If the results were unsatisfactory, further techniques were used to reach the goal.@*RESULTS@#During the operation 2 patients needed further techniques to make the mitral valve work well. No operative death and only 1 complication (low cardiac output syndrome) occurred. After 1 month follow-up later, mild regurgitation was found in 5 patients, moderate regurgitation in 1 and no obvious regurgitation in 6.@*CONCLUSION@#Evaluating the effect of mitral valvuloplasty by direct observation on beating heart is practicable.
