“…In recent reports of percutaneous and transapical AVR, investigators have used additive and logistic EuroSCOREs as evidence of the high operative risk with a traditional AVR in these patients. [6][7][8][10][11][12][13] Our study demonstrates that both the additive and logistic EuroSCORE models substantially overestimate mortality in all risk subgroups at a large-volume referral center.…”

Background-Aortic valve replacement with cardiopulmonary bypass is currently the treatment of choice for symptomatic aortic stenosis but carries a significant risk of morbidity and mortality, particularly in patients with comorbidities. Recently, percutaneous transfemoral aortic valve implantation has been proposed as a viable alternative in selected patients. We describe our experience with a new, minimally invasive, catheter-based approach to aortic valve implantation via left ventricular apical puncture without cardiopulmonary bypass or sternotomy. Methods and Results-A left anterolateral intercostal incision is used to expose the left ventricular apex. Direct needle puncture of the apex allows introduction of a hemostatic sheath into the left ventricle. The valve prosthesis, constructed from a stainless steel stent with an attached trileaflet equine pericardial valve, is crimped onto a valvuloplasty balloon. The prosthetic valve and balloon catheter are passed over a wire into the left ventricle. Positioning within the aortic annulus is confirmed by fluoroscopy, aortography, and echocardiography. Rapid ventricular pacing is used to reduce cardiac output while the balloon is inflated, deploying the prosthesis within the annulus. Transapical aortic valve implantation was successfully performed in 7 patients in whom surgical risk was deemed excessive because of comorbidities. Echocardiographic median aortic valve area increased from 0.7Ϯ0.1 cm 2 (interquartile range) to 1.8Ϯ0.8 cm 2 (interquartile range). There were no intraprocedural deaths. At a follow up of 87Ϯ56 days, 6 of 7 patients remain alive and well. Conclusions-This

“…Over the past 5 years, the development of minimally invasive transcatheter valve implantation has been explored. [2][3][4][5][6][7][8][9][10][11][12][13] Transarterial and transapical transcatheter aortic valve implantation (AVI) has been explored by cardiologists and cardiac surgeons worldwide. Many reports have shown favorable early clinical and echocardiographic outcomes with transarterial or transapical AVI.…”
