REOPERATION MITRAL VALVE REPLACEMENT UNDER CARDIAC FIBRILATION: A CASE REPORT WITH A THIRD OPEN HEART SURGERY

Öz

In reoperation heart surgery cases, there may be advanced adhesions in the paracardiac and surrounding aortic tissues, and this may prevent the routine cannulation protocol. Therefore, different surgical protocols may be required. In this study, a case of mechanical aortic valve replacement 29 years ago, ascending aortic replacement 5 years ago, and now mitral valve replacement is presented. The patient presented with complaints of dyspnea, fatigue and weakness. Advanced mitral regurgitation was detected in echocardiography, and mitral valve replacement was decided. In the second operation of the patient, a dacron graft was placed in the ascending aorta. The ascending aorta was highly adherent to the surrounding tissues due to the graft. Therefore, a cross-clamp could not be placed on the aorta and a different surgical procedure was required outside the routine. Mechanical mitral valve replacement was performed in the patient under left femoral cannulation and total circulatory arrest, without cross-clamping and in cardiac fibrillation. He was discharged on the 9th postoperative day with good recovery.

KARDİYAK FİBRİLASYON ALTINDA REOPERASYON MİTRAL KAPAK REPLASMANI: ÜÇÜNCÜ KEZ AÇIK KALP AMELİYATI YAPILAN BİR OLGU SUNUMU

Öz

Reoperasyon kalp cerrahisi vakalarında, parakardiyak ve aort çevresi dokularda ileri derecede yapışıklıklar olabilmekte ve bu durum rutin kanulasyon protokolünü engelleyebilmektedir. Bu nedenle farklı cerrahi protokoller gerekebilmektedir. Bu çalışmada 29 yıl önce mekanik aort kapak replasmanı, 5 yıl önce, asendan aort replasmanı ve şimdide mitral kapak replasmanı yapılan bir olgu sunuldu. Hasta dispne, çabuk yorulma ve halsizlik şikayetleri ile başvurdu. Yapılan ekokardiyografide ileri mitral yetmezliği saptandı ve mitral kapak replasmanı kararı verildi. Hastanın ikinci ameliyatında asendan aortaya dacron greft yerleştirilmişti. Greft nedeniyle asendan aort çevre dokulara ileri derecede yapışıktı. Bu yüzden aortaya kros klemp konulamadı ve rutinin dışında farklı bir cerrahi prosedür uygulanması gereksinimi doğdu. Hastaya sol femoral kanulasyon ve total sirkulatuar arrest altında, kross klemp konulmadan ve kardiyak fibrilasyonda mekanik mitral kapak replasmanı yapıldı. Postoperatif 9. Günde şifa ile taburcu edildi.
