Kardiyopleji tipinin seçimi konusunda bir fikir birliği olmamasına rağmen, kombine anteg- rad ve retrograd izotermik kan kardiyoplejisi kullanılmasıyla açık kalp ameliyatı sırasında yeterli miyokardiyal koruma sağlanabilir. Pompayla uygulanan retrograd kardiyoplejinin cerrahi manipulasyon esnasında basınç artmasına bağlı olarak zararı olabileceğinden, retrograd kardiyoplejik solüsyonunun yer çekimine bağlı pasif infüzyonu tercih edilebilir. Günümüzde hiperkalemik kardiyopleji altın standart olarak kullanılmaktaysa da, depola- rize arrest sağladığından aşırı sodyum ve kalsiyum yüklenmesine bağlı zararlı etkileri de vardır. Ancak, non-depolarize kardiyak arrest sağlayacak ideal kardiyopleji yöntemi geli- şinceye kadar Koşuyolu Kalp Merkezi tarafından modifiye edilen izotermik hiperkalemik kardiyopleji solüsyonu kullanılmaya devam edilebilir.

ABSTRACT
Although there is no consensus regarding the selection of cardioplegia type, adequate myocardial protection may be offered by antegrade and retrograde combined use of isothermic blood cardioplegia during open heart surgery. Delivery of retrograde cardioplegia with a volume pump may be harmful due to increased pressure during the surgical manipulation. Thus, passive continuous infusion of retrograde cardioplegic solution by gravitational force alone should be preferred. Nowadays, even though hyperkalemic cardioplegia is being used as the gold standard mondial; it has also harmful effects associated with ionic imbalance involving sodium and calcium overload of the myocyte induced by depolarization of the cell membrane. However, until the development of an ideal cardioplegic method providing non-depolarized cardiac arrest, isothermic hyperkalemic cardioplegia (modified by Koşuyolu Heart Center) may be used.
