Abstract

A 58-year-old man with a left ventricular assistdevice (LVAD), which had been implanted 1 year earlier,presented with rest dyspnea. Moderate to severe aorticregurgitation (AR), pre-postcapillary pulmonary hypertension, modarete right ventricular (RV) failure, and low cardiac output were observed at presentation. Transcatheteraortic valve implantation (TAVI) was performed to treatthe AR and a self-expandable aortic valve was implanted.Within minutes, hypotension, RV and inferior vena cava dilatation, and left atrial (LA) and left ventricular (LV) collapseoccurred and persisted despite LVAD speed reduction. Itwas observed that severe RV failure had developed andvenoarterial extracorporeal membrane oxygenation (VAECMO) was applied. Following VA-ECMO treatment, theRV dimensions decreased, and the LA and LV dimensionsbegan to increase, as well as the LVAD flw. Weaning fromVA-ECMO was unsuccessful and exitus occurred on thefith day after TAVI secondary to RV failure. It was surmisedthat the decrease in blood circulation from the aorta to theLV after treatment of severe AR with TAVI caused an acuteincrease in the cardiac output and the RV preload. Theacute increase in the RV preload led to acute severe rightheart failure. It is necessary to prepare the RV to competewith an acute increase in preload before TAVI even whenthere is only modarete RV failure.

Özet

Bir yıl önce, sol ventrikül destek cihazı (SVDC) implantasyon öyküsü olan 58 yaşında erkek hasta istirahat dispnesi ile başvurdu. Hastanın başvuru sırasında orta-ileri derecede aort yetersizliği (AY), pre-postkapiller pulmoner hipertansiyonu subklinik orta derece sağ ventriküler yetersizliği ve azalmış kardiyak debisi mevcuttu. AY tedavisi için transkatater aort kapak implantasyonu (TAVI) planlandı ve hastaya ‘self-expandable’ aort kapak takıldı. Hastada dakikalar içersinde hipotansiyon, sağ ventrikül ve inferiyor vena kavada dilatasyon, sol atriyum ve sol ventrikülde kollaps gelişti ve SCDC hızı azaltılmasına rağmen devam etti. SVDC hızının düşürülmesine rağmen kalp boşluklarının boyutlarında herhangi bir değişiklik görülmedi. Hastada ciddi sağ ventrikül yetersizliğinin geliştiğine karar verilerek veno-arteriyal EKMO tedavisi uygulandı. VA-EKMO’dan sonra sağ ventrikül boyutları azaldı, sol atriyum ve sol ventrikül boyutlarında ve SVDC akımında artış izlendi. Hasta sağ ventrikül yetersizliğinin devam etmesi nedeni ile EKMO’dan ayrılmadı ve işlemin 5. gününde hayatını kaybetti. Bu hastada, şiddetli AY’nin TAVI ile tedavisinden sonra aortadan sol ventriküle geri akımının azalmasının, kardiyak debi ve sağ ventrikül ön yükünde akut artışa ve sağ ventrikül ön yükündeki akut artışın da akut ciddi sağ kalp yetmezliğine neden olduğunu düşündük. Hastada orta derece sağ yetersizlik olsa bile, TAVI’den önce, sağ ventrikülü akut ön yük artışını tolere edebilecek şekilde medikal olarak hazırlamak gerekmektedir
