Aims: Transcatheter aortic valve implantation (TAVI) is frequently associated with cardiac conduction defects (CCD) requiring permanent pacemaker implantation (PPI). Although new-onset left bundle branch block (LBBB) is often seen, the rate of progression to severe CCD is unclear. We aimed to find clinical and electrocardiographic (ECG) parameters associated with severe CCD requiring PPI in patients with a new-onset LBBB after TAVI and assess its effect on clinical outcome. Methods and results: All consecutive patients undergoing TAVI who developed a new-onset LBBB were retrospectively analysed...

OBJECTIVES: Significant coronary artery disease (CAD) is common among patients evaluated for transcatheter aortic valve implantation (TAVI). Only little data exist on outcome of patients undergoing concomitant off-pump coronary revascularization and TAVI. The goal of this study was to analyse the impact of concomitant off-pump revascularization on early clinical outcome and 2-year follow-up of patients undergoing TAVI. METHODS: A total of 70 patients with significant CAD and aortic valve stenosis were included between January 2011 and January 2016...

Rapid ventricular pacing (RVP) is used during transcatheter aortic valve implantation (TAVI). RVP disturbs myocardial oxygen balance, and when prolonged, it may cause procedure-related myocardial injury (PMI). This study investigated whether a longer duration of RVP increased the occurrence of PMI or worsened long-term mortality after TAVI. We retrospectively analyzed data from 188 patients who underwent TAVI in our institute from January 2013 to July 2015. Myocardial injury was represented by the peak value of creatine kinase-myocardial band (CK-MB) within 72 h after the procedure; an increase greater than 5 times the upper reference limit was regarded as PMI...

Valve migration into the left ventricular outflow tract (LVOT) during transcatheter aortic valve implantation (TAVI) is a life-threatening complication. An 89-year-old female patient was admitted for TAVI due to severe symptomatic aortic stenosis. After deployment of a balloon-expandable prosthesis, the prosthesis had migrated into the LVOT. The prosthesis was reimpacted to the aortic annulus by a balloon-assisted recapture procedure. Immediately after recapturing the prosthesis with an oversized balloon, the patient's vital signs deteriorated due to acute aortic regurgitation (AR), and a prompt valve-in-valve (V-in-V) procedure allowed us to stabilize the patient's condition...

PURPOSE: The aim of this study was to report the safety of coronary rotational atherectomy (RA) in patients with severe aortic stenosis (AS). RA in the clinical setting seems challenging because coronary slow flow leads to hemodynamic instability. METHODS: Between October 2013 and May 2016, 1401 patients in the Optimized transCathEter vAlvular iNtervention (OCEAN) registry in Japan underwent transcatheter aortic valve implantation (TAVI). The primary study endpoint was procedural success, defined as residual stenosis <20% with final Thrombolysis in Myocardial Infarction flow 3...

The use of balloon aortic valvuloplasty (BAV) has increased with the development of transcatheter aortic valve implantation (TAVI) to medically optimize patients prior to procedure. It has been traditionally done by a retrograde approach via the femoral artery or an antegrade approach via the femoral vein. Large sheaths have been required with traditional balloons which require large vessel access. Use of a low profile compliant valvuloplasty balloon has been demonstrated to have adequate BAV results with smaller sheath sizes...

BACKGROUND: The use of transcatheter aortic valve implantation (TAVI) following the introduction of Nitinol autoexpandable devices has spread rapidly during recent years. In addition, cardiac surgery has been revolutionized due to the use of Nitinol-based sutureless prostheses for aortic valve replacement (AVR). During the same period, however, permanent pacemaker (PPM) implantation has emerged as a frequent complication. The study aim was to identify the risk factors of PPM following the implantation of a Nitinol self-expanding prosthesis (for AVR or TAVI)...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is a new treatment option for patients with severe aortic stenosis. Pre-TAVI procedure workup includes computed tomography angiography (CTA) of the heart and aorta from aortic annulus to the iliofemoral arteries. Frequently, there are a number of incidental non-cardiac findings (INCFs) in pre-TAVI CTA. However, the frequency and clinical significance of these INCFs are unknown. The aim of our study was to investigate the prevalence of INCFs and their clinical significance...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is a rapidly evolving technique for therapy of aortic stenosis. Previous studies report learning curves with respect to in-hospital mortality and clinical complications. We aim to determine whether observed improvements of in-hospital outcomes after TAVI are the result of improvements in procedures or due to a change in the patient population, and whether improvements differ between the transfemoral (TF) and the transapical (TA) approach...

The cardiac conduction system (CCS) is responsible for the initiation and propagation of action potentials through the heart ensuring efficient pumping of blood. Understanding the anatomy of the CCS and its relationship with other major cardiac components is important to help understand arrhythmias and how certain procedures may increase the incidence of arrhythmias developing. We sectioned a whole human heart and performed Masson's trichrome histology in order to identify the components of the CCS. The histology images were used to construct a 3D anatomical model...

AIM: The role of transoesophageal echocardiography in cardiac interventional structural procedures is well established and appreciated. However, the need for general anaesthesia (GA) throughout the procedure remains a controversial issue. The aim of the present study is to assess the feasibility and imaging quality of using a transnasal microrobe that allows the usage of conscious sedation in patients that undergo cardiac structural interventional procedures without missing the benefits, guidance and navigation of conventional trans-procedural TEE...

With increasing life expectancy, the epidemic of valvular heart disease, especially aortic stenosis (AS), is becoming more prevalent. Transcatheter aortic valve implantation (TAVI) has emerged as an alternative therapy for patients with significant aortic valve disease. It offers a less invasive procedure in comparison to surgical aortic valve replacement (sAVR) and an attractive substitute from the patient's perspective. The evidence for TAVI in inoperable and high risk surgical patients is now established and in the intermediate risk group has been accumulating rapidly and is looking favourable for TAVI...

BACKGROUND: Currently, the use of transcatheter aortic valve implantation (TAVI) is constantly increasing, whilst cardiosurgical back-up varies substantially. Besides immediate conversion to surgical aortic valve replacement (SAVR) for periprocedural complications, SAVR for TAV failure may be necessary within the early or late post-implant course. The etiology, incidence, risk-stratification, management and outcome for both scenarios are largely unclear. The study aim was to provide details of the authors' experience of SAVR after the failure of TAVI at a single institution...

BACKGROUND: The impact of various post-procedural complications after transcatheter aortic valve implantation (TAVI) on resource use and their consequences in the German reimbursement system has still not been properly quantified. METHODS: In a retrospective observational study, we use data from the German DRG statistic on patient characteristics and in-hospital outcomes of all isolated TAVI procedures in 2013 (N = 9147). The impact of post-procedural complications on reimbursement, length of stay and mechanical ventilation was analyzed using both unadjusted and risk-adjusted linear and logistic regression analyses...
