As the population ages, the prevalence of aortic stenosis is increasing. There is an unmet clinical need for the treatment of aortic stenosis in high-risk patients, who are often older, frail and have multiple comorbidities. Percutaneous aortic valve replacement (PAVR) is a new and innovative technique for the management of high-risk patients with aortic stenosis. There are currently two device...

INTRODUCTION AND OBJECTIVES Although changes in atrioventricular conduction frequently occur after percutaneous implantation of an aortic valve prosthesis, little is known about the mechanisms involved or how these changes progress. We investigated ECG abnormalities and predictors of pacemaker need after percutaneous implantation of the CoreValve® aortic valve prosthesis. METHODS Between Apri...

conclusions our anesthesia method was sciatic and femoral nerve block under double ultrasonic and nerve stimulator guidance. case presentation in this case report, we present a patient who had tibia and fibula fractures and a symptomatic severe critical aortic stenosis which was diagnosed during a preoperative visit. the patient had exertional dyspnea, palpitations and fainting history, but he ...

CLINICAL SUMMARY We describe the case of a 66-year-old man who had surgical intervention for a core valve malfunction 3 months after transfemoral implantation. The patient was scheduled for percutaneous aortic valve implantation (PAVI) because of the presence of numerous risk factors, such as obesity (body mass index, 35%) and myelodysplasia. The main concern about elective standard aortic valv...

The percutaneous treatment of valvular heart disease is rapidly progressing through clinical trials. For one valvular lesion, critical aortic stenosis, recent advances in technology and percutaneous techniques may potentially change the way in which we manage this disease in the most frail and elderly patients. Some of these new techniques blur the distinction between surgical and nonsurgical t...

After its first introduction in 2002, transcatheter aortic valve implantation (TAVI) has continuously gained more foothold for the treatment of severe aortic stenosis and is nowadays a viable treatment option for inoperable patients or patients at high risk for conventional surgical aortic valve replacement. Although ideally carried out in a so-called hybrid room, incorporating both the strict ...

OBJECTIVES To determine long-term results of aortic valve replacement (AVR) in patients 80 years old or older, and assess the factors influencing perioperative outcome. METHODS Data were reviewed on 83 consecutive octogenarians, undergoing aortic valve replacement between 1992 and 1997. There were 66 women and 17 men (mean age: 82.8 years). Fifty-seven patients (69%) were in New York Heart As...

Transcatheter aortic valve implantation (TAVI) was introduced five years ago (2007) as an alternative treatment for patients with severe aortic stenosis, who are considered at too high a risk for surgical replacement. Few cases of postoperative infection by TAVI device are reported in the literature. We report the case of a patient with Osler-Weber-Rendu (OWR) syndrome, in which the TAVI proced...

OBJECTIVES The purpose of this study was to demonstrate the feasibility and procedural outcomes with a new self-expanding and repositionable transcatheter heart valve. BACKGROUND Transcatheter aortic valve replacement is a viable option for selected patients with severe symptomatic aortic stenosis. However, suboptimal prosthesis positioning may contribute to paravalvular regurgitation, atriov...

OBJECTIVES The aim of this study was to assess the learning curve for the implantation of the percutaneous aortic valve via the transfemoral route. BACKGROUND Transcutaneous aortic valve insertion is a fundamentally new procedure for the treatment of aortic valve stenosis. The number of cases needed to gain proficiency with concomitant ease and familiarity (i.e., the "learning curve") with th...
