Clinical outcomes of transfemoral-transcatheter aortic valve implantation (TF-TAVI) versus surgical aortic valve replacement (SAVR) or transapical (TA)-TAVI are limited to a few randomized clinical trials (RCTs). Because previous meta-analyses only included a limited number of adjusted studies or several non-adjusted studies, our goal was to compare and summarize the outcomes of TF-TAVI vs SAVR and TF-TAVI vs TA-TAVI exclusively with the RCT and propensity-matched cohort studies with direct and adjusted indirect comparisons to reach more precise conclusions...

Transcatheter aortic valve replacement is a less invasive alternative for high-risk patients. However, valve embolization is a rare but dreaded complication. We report the successful off-pump retrieval of an embolized valve after transfemoral transcatheter aortic valve replacement through a left anterior thoracotomy. We maintained the embolized valve on the guidewire and snared it using a transapical approach. We then deployed a valve in an adequate position to ensure hemodynamic stability before transapical removal of the embolized valve...

A small-sized bioprosthesis can limit transcatheter valve-in-valve (V-in-V) implantations. The case is reported of a 91-year-old woman who had successfully undergone a V-in-V procedure with a 26 mm CoreValve in a previously implanted Mitroflow 19 mm valve. At the five-year follow up the prosthesis showed good echocardiographic function and the patient was alive and free from major symptoms. The patient died three months after the follow up examination at the age of 96 years. This case demonstrates the feasibility, with acceptable longterm functioning, of a V-in-V procedure involving a small bioprosthesis...

BACKGROUND: Various approaches such as antegrade trans-septal, retrograde transfemoral and transapical techniques have been used to close mitral paravalvular leak (PVL) in patients with an aortic prosthesis. During the implementation of these techniques, an arteriovenous guidewire loop is often created for device delivery. However, passing through a mechanical aortic valve may cause hemodynamic compromise and prolong the procedure. To date, no studies have evaluated antegrade mitral PVL closure without the use of an arteriovenous wire loop in patients with a mechanical aortic prosthesis...

During the past decade there has been a major shift in the use of surgical bioprostheses. Consequently, due to the increasing age of the population there will be a major increase in the incidence of failure of these prostheses. While mortality associated with the re-replacement of surgical valve failures remains high, advances in transcatheter interventions have permitted the use of transcatheter valves in degenerative surgical bioprostheses. Herein is described the first use of the Symetis transfemoral ACURATEneo™ valve-in-valve procedure, together with details of the associated technical challenges...

Transcatheter aortic valve replacement (TAVR) in the presence of a mechanical mitral valve (MMV) prosthesis is challenging due to the stiff mitral cage in the boundaries of the aorto-mitral curtain. We describe the technique for TAVR using the ACURATE-neo™ aortic bioprosthesis in a patient with a MMV prosthesis.

Percutaneous coronary intervention is commonly used to treat coronary artery disease. Both transradial and transfemoral approaches are applied. In general, fewer complications are seen with the transradial approach compared to the transfemoral access, for which reason the transradial catheterization is frequently preferred. In this case presentation, we describe 2 cases of elective transradial coronary angiography both resulting in severe central vascular complications: perforation of the right subclavian artery with a mediastinal hematoma and dissection of the brachio-cephalic trunk and the aortic arch...

Transcatheter aortic valve replacement (TAVR) has become a widely accepted therapeutic option for patients with severe, symptomatic aortic stenosis at intermediate, high, or extreme risk for conventional surgery as determined through a heart team approach. Two valve prostheses are currently available and the Food and Drug Administration (FDA) approved in the United States for TAVR: the self-expandable Medtronic CoreValve (Medtronic, Inc., Minneapolis, MN, USA) and the balloon-expandable Edwards Sapien Valve (Edwards Lifesciences, Irvine CA, USA)...

Delayed aortic regurgitation following Valsalva sinus re-dissection is a well-known complication that can occur at any time after surgery for type-A aortic dissection without root replacement. We describe a case of acute type-A dissection in an 81-year-old lady successfully treated with aortic valve resuspension and ascending aorta replacement with a 28-mm vascular graft. A month later, the patient was readmitted for worsening heart failure and a transthoracic echocardiogram showed severe aortic regurgitation secondary to non-coronary Valsalva sinus re-dissection and non-coronary aortic valve leaflet prolapse also confirmed at computed tomography scan...

Background Transcatheter aortic valve implantation has been established as a safe and effective treatment option for patients at high or prohibitive surgical risk. However, some patients may not be suitable for the transfemoral approach due to severe iliofemoral disease or aneurysmal disease of the thoracoabdominal aorta. The aim of this case series was to evaluate the feasibility and clinical outcomes of the transaortic approach. Methods From May 2015 to June 2016, 5 patients (mean age 78.4 ± 3.9 years) with severe symptomatic aortic stenosis underwent transaortic transcatheter aortic valve implantation after a heart team discussion...

Carbon fiber running-specific prostheses are designed to reproduce the spring-like stepping behavior of individuals similar to springs loaded by the entire body mass (i.e. spring-mass model). The aim of this study was to test whether leg stiffness would be modulated differently between intact and prosthetic legs in transfemoral amputees wearing RSP during sprinting. Eight unilateral transfemoral amputees performed maximum sprinting along an indoor overground runway. Leg stiffness was calculated from kinetic and kinematic data in intact and prosthetic legs...

Transcatheter Aortic Valve Implantation (TAVI) has revolutionized the treatment of elderly patients with symptomatic severe aortic stenosis (AS). Initially tested in unoperable or high surgical risk patients, the safety and efficacy of TAVI has progressively improved, with increasing operators' experience and continuous technical refinements of the devices and of the delivery systems. Hence, the extension of clinical indications for TAVI to the intermediate-risk population has been attracting cardiologists in recent years...

BACKGROUND: Feasibility of transfemoral (TF) transcathteter aortic valve replacement (TAVR) is limited by the smallest diameter, the calcification and tortuosity of the iliofemoral access vessels. The use of the Portico system without delivery sheath results in significantly lower profile delivery system compared to standard technique. We herein report our single center experience, feasibility and safety of such an approach. METHODS: The Portico valve was implanted sheathless in 81 high-risk patients with severe aortic stenosis utilizing percutaneous femoral access...
