Transkateter aort kapak implantasyonu yapılan hastaların sonuçları: Tersiyer bir merkezin 2 yıllık deneyimi

Giriş ve Amaç: Bu çalışmada merkezimizde transkateter aortik kapak implantasyonu (TAVİ) uygulanan hastaların erken ve geç dönem klinik ve ekokardiyografik takip sonuçları değerlendirildi.Hastalar ve Yöntem: 2011-2013 yılları arasında kliniğimizde ciddi aort darlığı (AD) nedeni ile TAVİ uygulanan 48 hastanın erken ve geç dönem sonuçları değerlendirildi. Tüm hastalara transfemoral yaklaşım ile CoreValve biyoprotez kapak yerleştirildi ve hastalar 17,4±15,3 ay takip edildi.Bulgular: Hastaların (24’ü kadın, ortalama yaş 77,4±8,1) işlem öncesi ortalama aortic kapak alanı (AVA) 0,7±0,2 cm2, ortalama aortik kapak gradiyenti (MnG) 55,4±19,8 mmHg, fonksiyonel sınıfı New York Kalp Cemiyeti (NYHA)’ne göre 2,5±0,4 iken, TAVİ işlemini takiben AVA, MnG ve fonksiyonel sınıflamalarında anlamlı düzelme görüldü. İşlem başarısı %87,5 olup, hastalara ortalama 1,5±0,5 kapak implante edildi. 1 hastada kapak implantasyonu sonrası hemodinamiyi bozan ileri paravalvüler AY geliştiği için cerrahi aort kapak replasmanı yapıldı. İşlemde 3 hastada AV tam blok, 2 hastada koroner obstrüksiyona bağlı ventriküler taşikardi; işlem sonrası erken dönemde ise 3 hastada geçici iskemik atak, 2 hastada minör kanama gelişti. 3 hasta işlemde gelişen kalp tamponadı nedeniyle, 1 hasta işlem sonrası 28. gün enfeksiyon ve sepsis nedeniyle, 2 hasta kompleks ventriküler artimiye bağlı kardiyak arrestten, 2 hasta da 1. ve 4. aylarda kalp dışı nedenlerden hayatını kaybetti. İşlemin 3 yıllık yaşam süresi %75 bulundu.Sonuç: Cerrahi riski yüksek veya opere edilemeyecek olan semptomatik AD hastalarında, cerrahiye alternatif bir tedavi yöntemi olarak klinik pratiğe girmiş olan TAVİ işlemi, erken ve geç dönem sonuçları itibariyle başarılı ve güvenilir bir yöntemdir.

Results of patients who underwent transcatheter aortic valve implantation: 2 years experience of a tertiary center

Background: The early and late term results of who underwent transcatheter aortic valve implantation (TAVI) in our center were evaluated in this study.Patients and Methods: The early and late term results of 48 patients with severe aortic stenosis who underwent the TAVI procedure in our clinic between 2011 and 2013 years were evaluated. All of our patients were implanted with CoreValve bioprosthetic valves through the transfemoral approach and followed-up for 17.4±15.3 months.Results: Before the procedure, the mean aortic valve area (AVA) was 0.7±0.2cm2, the mean valvular gradients (MnG) were 55.4±19.8 mmHg and the mean functional class was 2.5±0.4. Following the TAVI procedure the AVA, MnG and functional class were improved, significantly. The technical success rate was %87.5, and mean 1.5±0.5 valves was implanted in all patients. Surgical AVR was required for 1 patient because of severe paravalvular leakage. At the procedure, in 3 patients third degree atrioventricular (AV) block and in 2 patient coronary occlusion were developed. The patients with third degree AV block was required permanent pacemaker. In the early term after TAVI in 3 patients transient ischemic attack and in 2 patients minors hemoragy were developed. 3 patient was dead of cardiac tamponade in the procedure, 1 patient was dead from infections and sepsis postoperative 28th days, 2 patients were dead from cardiac arrest because of complex ventricular arrythmia, 2 patients were dead of noncardiac reasons on the 1st and 4th months, respectively. In this study 3 years survi of TAVI procedure was %75.Conclusion: In the patients with high surgery risk or inoperable aortic stenosis TAVI is a rather safe and successful method in the early and late terms as an alternative therapy to surgery.
