OBJECTIVE Transcatheter aortic valve implantation (TAVI) has become an alternative to surgical aortic valve replacement (sAVR) in selected high risk patients. While improvement in left ventricular function after TAVI has been demonstrated, little is known about the impact on right ventricular (RV) function. Since postoperative RV dysfunction is linked to adverse outcomes, the authors sought to ...

Percutaneous trans-catheter aortic valve implantation (TAVI) is recommended for inoperable patients with severe aortic stenosis at high risk for conventional aortic valve replacement. Originally, TAVI was mostly performed under general anesthesia. Here we describe two cases of transfemoral TAVI performed under monitored anesthesia care (MAC) with dexmedetomidine. Dexmedetomidine provides sedati...

Background Transcatheter Aortic Valve Implantation (TAVI) represents a new reasonable therapeutic approach in patients with severe aortic stenosis and a high risk for conventional surgery. The most common approach for TAVI remains the peripheral arteries, but in the recent years a transapical and transaortic approaches (TaoTAVI) have been described. In this context, we report our experience wit...

Transcathater aortic valve implantation (TAVI) has emerged as a promising alternative for patients with severe, symptomatic aortic stenosis who are not candidates for surgery due to high comorbidity and operation mortality (1, 2). Transfemoral approach (TF) is the generally accepted route for TAVI. However, small vessel diameter and peripheral arterial disease hinder this access (3). Presently ...

The last decade has seen transcatheter aortic valve implantation (TAVI) emerge as the standard of care for patients with severe symptomatic aortic stenosis deemed to be either at excessiveor high-risk for surgical aortic valve replacement (SAVR). This position is supported by three important multicentre randomized trials comparing TAVI to the historical gold standard therapies: (1) The Placemen...

OBJECTIVES Transcatheter aortic valve implantation (TAVI) does not enable concomitant or simultaneous ascending aortic intervention. This investigation evaluates the safety of TAVI in patients with ascending aortic dilatation and demonstrates mid-term follow-up. METHODS From November 2007 to December 2012, among 1143 patients with severe aortic stenosis screened for TAVI, a cohort of 457 pati...

BACKGROUND Transcatheter aortic valve implantation (TAVI) has become the treatment of choice in patients with severe aortic valve stenosis who are not eligible for operative replacement and an alternative for those with high surgical risk. Due to high age and smoking history in a high proportion of TAVI patients, suspicious findings are frequently observed in pre-procedural chest computer tomog...

BACKGROUND Trans-catheter aortic valve implantation (TAVI) has recently emerged as an alternative to conventional surgery in high-risk surgical patients with haemodynamically significant aortic valve stenosis. However, patients referred for TAVI are usually elderly individuals (> 80 years) who frequently also suffer from renal impairment. Trans-catheter valve therapies require extensive use of ...

Severe aortic stenosis is the most common valvular heart disease in the elderly in the Western world and contributes to a large proportion of all deaths over the age of 70. Severe aortic stenosis is conventionally treated with surgical aortic valve replacement; however, the less invasive transcatheter aortic valve implantation (TAVI) is suggested for those at high surgical risk. While TAVI has ...

OBJECTIVES Transcatheter aortic valve implantation (TAVI) has emerged rapidly. Despite unanimous recommendations and potentially fatal intraoperative complications, the heart-team approach is not comprehensively adopted by all centres. We sought to characterize severe intraprocedural complications during TAVI requiring immediate surgical or interventional bailout manoeuvres and evaluate outcome...
