Son dönem kalp yetmezliği olan hastalarda karara köprülemede Levitronix CentriMag ventriküler destek cihazı: Tek merkez deneyimimiz

Amaç: Bu çalışmada tek bir merkezde son dönem kalp yetmezliği olan hastalarda karara köprülemede Levitronix CentriMag ventriküler destek cihazı implantasyonunun erken dönem sonuçları sunuldu. Çalışma planı: Aralık 2010 - Eylül 2014 tarihleri arasında, karara köprüleme amacıyla Levitronix CentriMag desteği uygulanmış olan toplam 41 son dönem kalp yetmezliği hastasının (30 erkek, 11 kadın; ort. yaş 30.2±15 yıl; dağılım 7-59 yıl) verileri retrospektif olarak incelendi. Cihazlar sol (n=38), sağ (n=1) veya biventriküler (n=2) konfigürasyonda yerleştirildi. Destek iyileşmeye, transplantasyona veya uzun dönem ventriküler destek cihazı takılana kadar sürdürüldü. Bulgular: Hastaların ameliyat öncesi ortalama sol ventrikül ejeksiyon fraksiyonları %17±2.3 idi. Ortalama destek süresi 38 (dağılım 1-192) gündü. On altı hasta (%39) yaşamını sürdürdü ve tedavinin bir sonraki aşamasına geçti. Bu hastalardan 11’ine (%27) kalp nakli yapıldı ve beş hastaya (%12) uzun dönem ventriküler destek cihazı yerleştirildi. CentriMag yerleştirildikten sonra 30 günlük sağkalım oranı 20 hastada %49 idi. On üç hastada (%32) yeniden ameliyat gerektiren kanama gözlendi. İki hastada (%4.8) sternal yara enfeksiyonları vardı. Bir hastada (%2.4) cihaz disfonksiyonu gözlendi. Sağkalan hastalara kıyasla, kaybedilen hastalarda daha yüksek oranda sepsis ve renal yetmezlik vardı (p

The Levitronix CentriMag ventricular assist device as a bridge to decision in patients with end-stage heart failure: Our single-center experience

Background: In this study, we report early outcomes of Levitronix CentriMag device implantation for bridge to decision for patients with end-stage heart failure in a single center.Methods: We retrospectively analyzed data of a total of 41 patients(30 males, 11 females: mean age 30.2±15 years; range 7 to 59 years) with end-stage heart failure who received a Levitronix CentriMag support for bridge to decision between December 2010 and September 2014. Devices were implanted in the left (n=38), right (n=1), or biventricular (n=2) configuration. Support was continued until recovery, transplantation or implantation of a long-term ventricular assist device.Results: The mean preoperative left ventricular ejection fraction was 17±2.3%. The mean support time was 38 (range 1 to 192) days. Sixteen patients (39%) survived and moved on to the next phase of the treatment. Of these patients, 11 (27%) underwent cardiac transplantation operations and five (12%) received long-term ventricular assist devices. After the CentriMag implantation, 30-day survival rate was 49% in 20 patients. Bleeding requiring re-operation was observed in 13 patients (32%). Two patients (4.8%) had sternal wound infections. Device dysfunction was observed in one patient (2.4%). Non- survivors had a higher rate of sepsis and renal failure, compared to the survivors (p
