BACKGROUND: Thinning of anterolateral thigh (ALT) flaps has been described to achieve optimal contouring. Previous studies caution against thinning large flaps owing to the risk of vascular compromise leading to partial or total flap necrosis. This study aims to demonstrate a reliably safe method for thinning extra-large (>240 cm) flaps. METHODS: A retrospective review of 53 consecutive ALT flaps performed at a single institution was completed. Of these flaps, 18 (34%) were thinned primarily by sharp excision of sub-Scarpa's fat along the periphery of the flap using loupe magnification...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has revolutionized the prognosis of inoperable patients with severe aortic valve stenosis. Yet, the implantation of expensive prostheses in patients with comorbidities may be questionable in an era when healthcare costs are becoming a major concern. AIM: The objective of this study was to assess whether the TAVR procedure is profitable in a high-volume French hospital. METHODS: Consecutive patients eligible for transfemoral TAVR using the SAPIEN bioprostheses (Edwards Lifesciences, Irvine, CA, USA) were included retrospectively in this single-centre study between September 2014 and December 2015...

BACKGROUND: The balloon-expandable Sapien 3 (Edwards Lifesciences, Irvine, CA, USA) and the mechanically-expandable Lotus valve (Boston Scientific, Marlborough, MA, USA) are established devices for transcatheter aortic valve implantation. We sought to compare both transcatheter heart valves (THV) under consideration of the extent of THV landing zone calcification. METHODS: This retrospective analysis includes consecutive patients with severe aortic stenosis treated with Sapien 3 (S3; n=212) or Lotus (n=61) THV via transfemoral access...

OBJECTIVES: The Ross procedure has demonstrated excellent results when performed in patients with aortic stenosis or mixed aortic valve disease [aortic stenosis and aortic regurgitation (AR)]. However, due to its reported risk of late reoperation, it is not recommended under current guidelines for patients presenting with bicuspid aortic valve and pure AR. We have analysed our own results in light of this recommendation. METHODS: Between 1993 and 2016, 129 consecutive patients with a mean age of 34...

The aim of the present in vitro study was the evaluation of the fluid dynamical performance of the Carpentier-Edwards PERIMOUNT Magna Ease depending on the prosthetic size (21, 23, and 25 mm) and the cardiac output (3.6-6.4 L/min). A self-constructed flow channel in combination with particle image velocimetry (PIV) enabled precise results with high reproducibility, focus on maximal and local peek velocities, strain, and velocity gradients. These flow parameters allow insights into the generation of forces that act on blood cells and the aortic wall...

In almost every type of artificial valve, structural failure has been described. We are reporting on a case of a sudden leaflet escape of an Edwards TEKNA mitral valve prosthesis 12 years after implantation. The patient had a sudden onset of dyspnea and severe pulmonary edema with subsequent cardiogenic shock. An emergency mitral replacement was successfully performed. A multi-detector computed tomography scanning and three-dimensional imaging showed two fragments that had embolized in the terminal aorta and the left common iliac artery...

OBJECTIVES: The aim of this study is to describe electrocardiographic changes and conduction abnormalities in patients undergoing transcatheter aortic valve implantation (TAVI). METHODS: 76 patients who underwent TAVI using Edwards Sapien 3 prosthesis were included, comparing electrocardiographic registries at admission, post-procedure and before discharge. RESULTS: Patients after TAVI presented a longer PR interval, a wider QRS, and a longer corrected QT, with a left deviation of QRS axis and T waves; reversible changes that tended to correct in the following days after TAVI...

AIMS: Paravalvular leak(PVL) remains an important issue in TAVI. The Edwards Sapien3(S3) valve has reduced PVL but up to one-third of patients remain with mild leak. Our study aims to identify predictors of mild PVL after TAVI with S3 valve. METHODS AND RESULTS: From 10/2015 to 5/2017, 122 consecutive patients underwent S3 TAVI for symptomatic severe aortic stenosis. 33 patients with mild PVL on transthoracic echocardiography at 30-day follow-up were compared to 89 with none/trace PVL...

OBJECTIVE: Recently, the PARTNER 2A trial reported results of transcatheter aortic valve replacement versus surgical aortic valve replacement in 2032 intermediate-risk patients at 2 years. Two hundred thirty-six patients (24%) required an access route other than transfemoral. Compared with transfemoral and surgical aortic valve replacement, nontransfemoral transcatheter aortic valve replacement was associated with a numerically higher rate of death and disabling stroke at 30 days. This underscores the need for a better alternative surgical approach for patients with marginal femoral access...

The ventriculosinus shunt is a promising treatment for hydrocephalus. Currently, different shunt techniques exist, and it is not clear whether one is preferable. This pilot study reports on a non-hydrocephalic goat model (Saanen breed) that provides opportunities to evaluate and optimize several aspects of the ventriculosinus shunt technique. Analysis of the coagulation properties of 14 goats by a viscoelastic coagulation monitor showed that goats have a hypercoagulable state compared to humans. This property can be partially counteracted by antiplatelet drugs...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is associated with a high incidence of cerebrovascular injury. As these injuries are thought to be primarily embolic, neuroprotection strategies have focused on embolic protection devices. However, the topographical distribution of cerebral emboli and how this impacts on the effectiveness of these devices have not been thoroughly assessed. Here, we evaluated the anatomical characteristics of magnetic resonance imaging (MRI)-defined cerebral ischemic lesions occurring secondary to TAVI to enhance our understanding of the distribution of cardioembolic phenomena...

OBJECTIVES: Mitral valve replacement using a bioprosthesis remains controversial in young patients because data on long-term outcomes are missing. This study evaluated the long-term results of the PERIMOUNT pericardial mitral bioprosthesis in patients aged 65 years or younger. METHODS: From 1984 to 2010, 148 Carpentier-Edwards PERIMOUNT mitral bioprostheses were implanted in 148 patients aged 65 years or younger. Baseline clinical, perioperative and follow-up data were recorded prospectively...

OBJECTIVE: This first-in-human study evaluated the safety and technical feasibility of the Tempo temporary cardiac pacing lead (BioTrace Medical), which includes a novel fixation mechanism and soft tip. BACKGROUND: Complications of temporary pacing leads include dislodgment, arrhythmias, and ventricular perforation. Temporary pacing applications have increased with transcatheter aortic valve replacement (TAVR) growth, for rapid pacing during balloon valvuloplasty (BAV) and valve deployment, and for periprocedural bradyarrhythmia support...

BACKGROUND: Clinical indications for transcatheter aortic valve replacement (TAVR) and elements of the implantation procedure, including delivery system miniaturization and novel access options, have evolved over time. The reasons patients are excluded from TAVR also have changed. The impact of these changes on patient referral for and exclusion from TAVR is unknown. METHODS: We retrospectively analyzed patients referred to our center for TAVR from January 2010 to August 2016 to evaluate reasons for patient exclusion...

OBJECTIVES: This study sought to evaluate the long-term clinical impact of permanent pacemaker implantation (PPI) after transcatheter aortic valve replacement (TAVR). BACKGROUND: Conduction disturbances leading to PPI are common following TAVR. However, no data exist regarding the impact of PPI on long-term outcomes post-TAVR. METHODS: This was a multicenter study including a total of 1,629 patients without prior PPI undergoing TAVR (balloon- and self-expandable valves in 45% and 55% of patients, respectively)...

Nowadays, percutaneous pulmonary valve implantation (PPVI) is a suitable alternative to surgical procedure in patients with right ventricle outflow tract dysfunction. Two valves are currently available for PPVI: the Melody valve and the Edwards Sapien valve. The following complications may occur: coronary artery compression, deformation of the aortic root, stent or valve embolization, damage of distal pulmonary arteries, access site injuries. Here, we report on three cases of severe tricuspid regurgitation due to valvular and subvalvular apparatus damage during Edwards Sapien XT valve implantation...
