INTRODUCTION: Percutaneous aortic valve replacement represents an alternative to conventional open-heart surgery for selected high-risk patients without the need for sternotomy, aortotomy, or cardiopulmonary bypass. We present the first Greek series of transcatheter prosthetic aortic valve implantation procedures, performed in our centre. METHODS: All 12 patients (age 81 +/- 5 years) had severe, symptomatic, calcific aortic stenosis and were judged not to have a reasonable surgical option by a medical team including experienced cardiac surgeons. The patients' mean logistic EuroSCORE was 34 +/- 15% (min 11%, max 61%). Eight (8) of them underwent transfemoral (SAPIEN, Edwards 23 mm valve in 7 and 26 mm in 1 patient) and 4 transapical (26 mm in 2 and 23 mm in 2 patients) prosthetic aortic valve implantation, all in the cardiac catheterisation laboratory under general anaesthesia. RESULTS: The procedural, in-hospital and 2-month (mean follow up 50 days, min 17, max 122 days) mortality was 0%. The length of hospital stay was 8 +/- 2 days (min 5, max 12 days). The aortic valve area increased from 0.64 +/- 0.14 cm2 to 1.83 +/- 0.14 cm2 and the mean pressure gradient decreased from 57 +/- 23 mmHg to 10 +/- 3 mmHg post-implantation (p<0.001 for both). The patients' mean NYHA functional status improved from 2.8 +/- 0.7 to 1.3 +/- 0.5 at follow-up (p<0.001). CONCLUSIONS: Our initial experience with transcatheter prosthetic aortic valve implantation demonstrates that it can be performed safely and with excellent short and mid-term clinical outcomes.
