| pubmed-article:511907 | pubmed:abstractText | Our entire experience (33 patients) of combined aortic and mitral valve replacement was reviewed. In 20 patients, coronary perfusion with moderate hypothermia (28-32 degrees C) was used with 7 operative deaths (35% mortality). Catecholamines were used in 14 patients (70%). Potassium cardioplegia was used in 13 patients with no mortality (P less than 0.02) and use of catecholamines in only 4 (P less than 0.05). These data suggest that potassium cardioplegia is the method of preference for myocardial preservation for combined aortic and mitral valve replacement. | lld:pubmed |
