PURPOSE: Emerging research explores the educational implications of practice and procedural variation between faculty members. The potential effect of these variations on how surgeons make competence judgments about residents has not yet been thoroughly theorized. The authors explored how thresholds of principle and preference shaped surgeons' intraoperative judgments of resident competence. METHOD: This grounded theory study included reanalysis of data on the educational role of procedural variations and additional sampling to attend to their impact on assessment...

AIMS: We sought to evaluate the impact of permanent pacemaker (PPM) implantation on two-year mortality and one-year left ventricular ejection fraction recovery (∆LVEFR=one-year LVEF-baseline LVEF) after transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS: We pooled patient-level data from four European institutions with significant TAVI volume. Outcomes were compared between patients without PPM (no-PPM), patients with PPM prior to TAVI (old-PPM) and patients with PPM implanted after TAVI (new-PPM)...

BACKGROUND: In patients treated with transcatheter aortic valve implantation (TAVI), age is recognized as one of the most important risk factors. The aim of our study was to evaluate whether early and mid-term results of TAVI were worse in patients over 85 year old compared with the younger population. METHODS: From September 2010 to November 2015, 162 consecutive patients (mean age 78.4 ±7.1 years, 47.5 % females) underwent TAVI in our Institution. Patients were divided into two groups: 1) elderly (≥ 85 year old) and 2) younger patients (< 85 year old)...

: Transcatheter aortic valve implantation (TAVI) and balloon aortic valvuloplasty (BAV) are now well established percutaneous procedures. These procedures almost always require bursts of rapid ventricular pacing to temporarily reduce cardiac output to facilitate the procedure, usually done via a temporary pacing wire inserted into the right ventricle. We describe a case series of 132 cases of TAVI and 76 BAV done using ventricular pacing via the left ventricular lead by simply connecting one electrode to the patient's skin and one electrode through the left ventricular (LV) wire...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is presently a recognized treatment modality for patients with severe aortic stenosis ineligible for surgery. It reduces mortality as compared to the conservative treatment. It is further expected from this therapy to improve quality of life by improving of the cardiovascular function performance. The aim of this study is to compare patients' cardiovascular system efficiency in the 6-minute walk test (6MWT) made before and after TAVI and at the 6-12-month follow-up...

OBJECTIVES: Aortic valve preparation with balloon aortic valvuloplasty (BAV) has been previously considered mandatory during transcatheter aortic valve implantation (TAVI) procedures. BAV-inherent risks including stroke, conduction abnormalities, and reduced device profile size established the rationale for safe valve deployment without the need for aggressive valve preparation. We investigate the feasibility and safety of performing Sapien 3 (S3; Edwards Lifesciences) balloon-expandable TAVI with moderate or without predilation (PD)...

BACKGROUND: About one-third of candidates for transcatheter aortic valve implantation (TAVI) suffer from severe peripheral artery disease, making the routine femoral approach difficult or impossible. Aim was to compare the trans-axillary (TAx) and the trans-aortic (TAo) route for TAVI with Medtronic CoreValve Revalving System (CRS). METHODS: 242 (23%) out of 1049 consecutive TAVI with 18F CRS were treated in 4 high-volume Italian Centre through TAx (61%) and TAo (39%)...

INTRODUCTION: Transcatheter aortic valve implantation (TAVI) in patients with degenerated bioprosthetic aortic valve has been successfully performed as an alternative to surgery. We describe our initial experience of valve-in-valve TAVI in five patients, using new generation Edwards Sapien 3 transcatheter heart valves implanted into degenerated 19 mm bioprosthetic valves. 20-mm Edwards S3 valves were offered for compassionate use. All patients had significant aortic valve stenosis. METHODS AND RESULTS: The main vascular access was achieved and pre-closed with two Proglide closure devices in one patient and Prostar closure devices in four patients...

Transcatheter aortic valve implantation (TAVI) is nowadays a worldwide technique in the field of treating aortic stenosis. One of the main side effects linked to the technique are mostly attached to rhythm disturbances, such as atrioventricular (AV) and intraventricular blocks. Consequently, a pacemaker implantation is often required. That implantation rate is estimated between 8 and 30%, depending on the valve chosen. Thanks to main meta analysis on the subject, it has been managed to isolate the following risks factors for AV block development: preoperative right bundle branch block (RBBB: the most powerful element), complete AV block during the procedure, male gender, a so-called porcelain aorta, the absence of previous valvular surgery, the aortic annulus size (i...

BACKGROUND: Despite the completion of more than 60,000 transcutaneous aortic valve implantations (TAVI) per year and an approximately 10-15 % incidence of vascular access site complications (VAC), there is a paucity of data on the efficacy and safety of percutaneous VAC treatment. HYPOTHESIS: Percutaneous endovascular treatment will be an effective treatment of VAC and associated with a low rate of surgical repair. Despite stent placement in proximity to the hip joint, endovascular treatment will be only rarely associated with disabling symptoms or complications...

Transcatheter aortic valve implantation (TAVI) decreases mortality in high-risk patients with severe aortic stenosis, but it remains unclear if female gender is associated with more favorable outcomes after TAVI. All patients who underwent TAVI at a single institution were retrospectively analyzed and stratified by gender. Procedural, in-hospital, 30-day, and 1-year outcomes were defined according to the second Valve Academic Research Consortium. The primary end point was all-cause mortality at 1 year. Kaplan-Meier survival analysis and multivariable Cox proportional hazards regression were conducted...

Transcatheter aortic valve implantation (TAVI) has transformed the treatment of severe aortic stenosis. Here, we present a case of late aortic root rupture presenting as ST-elevation myocardial infarction five weeks following successful TAVI. Aortic root rupture is a rare complication of TAVI, which occurs in ∼1% of procedures and usually arises during or soon after the procedure and is associated with high mortality (∼50%). Early recognition of late-presenting complications related to TAVI, including aortic root rupture, is essential for specialists and nonspecialists...

Cerebral embolization during transcatheter aortic valve implantation (TAVI) can lead to a spectrum of clinically relevant manifestations, ranging from overt stroke to mild neurologic or cognitive deficits and subclinical cerebral infarcts. This study sought to determine the frequency of neurologic injury, cerebral ischemic lesions, and cognitive dysfunction in subjects undergoing contemporary commercial TAVI in the United States. Neuro-TAVR is the first prospective, multicenter study to use serial systematic neurologic and cognitive assessments and diffusion-weighted magnetic resonance imaging (at 4 ± 2 days after procedure) to investigate the incidence and severity of neurologic injury after contemporary unprotected TAVI in the United States...
