Thorough imaging of the aortic valve and related structures is highly important before and during percutaneous valve implantation. However, imaging modalities currently used in the catheterization room, namely, conventional aortography and transesophageal echocardiography are limited in guiding the precise valve placement during the implantation procedure. A novel real-time imaging modality cap...
RATIONALE Percutaneous aortic valve procedures are a major breakthrough in the management of patients with aortic stenosis. Residual gradient and residual aortic regurgitation are major predictors of midterm and long-term outcome after percutaneous aortic valve procedures. We hypothesized that (1) induction/recovery of high molecular weight (HMW) multimers of von Willebrand factor defect could ...
Percutaneous valve replacement for severe aortic stenosis has been shown to be an alternative treatment option for high surgical risk patients. We describe our first valve-in-valve procedure in a patient with a degenerated aortic bioprosthesis and severe regurgitation.
Aortic valve replacement with mechanical or biological prosthesis with extracorporeal circulation is the gold-standard for the treatment of calcific aortic stenosis. Although the results are excellent with the conventional approach some elderly patients, with multiple high-risk comorbid conditions, reoperations and severe left ventricular dysfunction have high surgical risk. During the last yea...
OBJECTIVES We describe procedural and clinical outcomes in a high-risk cohort undergoing transcatheter aortic valve replacement with early next-generation transcatheter valve and delivery systems. BACKGROUND Percutaneous aortic valve replacement is gaining acceptance as a viable option in patients at high surgical risk. Broader application will require further advances in valve and delivery s...
Patients with symptomatic aortic stenosis have a very poor prognosis on medical treatment. In those with contraindications to surgery, percutaneous valve replacement has been proposed as an alternative. We report on physicians' initial experience in Spain with percutaneous aortic valve replacement. We analyzed inhospital and short-to-medium-term findings in four patients who underwent percutane...
OBJECTIVES The goal of this study was to evaluate the role of percutaneous aortic valvuloplasty in patients with cardiogenic shock due to severe aortic stenosis and associated major comorbid conditions and to establish predictors of survival. BACKGROUND The prognosis for patients in cardiogenic shock with severe aortic stenosis is poor. Aortic valve replacement can be lifesaving, but the pres...
INTRODUCTION Percutaneous retrograde transfemoral or transsubclavian aortic valve replacement is a minimally invasive method of aortic valve replacement in elderly and high-risk patients with symptomatic aortic stenosis considered too fragile to go through conventional heart surgery. The purpose of this study was to compare two different anaesthetic techniques for percutaneous retrograde transf...
Transcatheter aortic valve implantation (TAVI) is assuming a major role in the routine management of patients with aortic stenosis. Surgical aortic valve replacement is generally accepted to prolong survival, on the basis of historical comparisons and long experience. However, recently percutaneous transarterial TAVI has assumed the position as the only therapy in any aortic stenosis patient gr...
Background Transcatheter aortic valve implantation (TAVI) is an alternative that offers hope to patients who are older, or have contraindication to conventional surgical aortic valve replacement due to considerable comorbidities. In our country there is about 500 to 1000 patients, older than 80 years needing this, less invasive procedure. The aim of this study was to asses the number of high-ri...
