Some cryptogenic strokes are caused by undetected paroxysmal atrial fibrillation (AF) and could benefit from oral anticoagulation. In this study, we searched for echocardiographic parameters associated with first diagnosed AF, to form a scoring system for the identification of patients with AF. We examined 571 patients with ischemic stroke (72.7 ± 13.5 years, 50.6% women), subdivided into 4 groups: documented cause without AF, first diagnosed AF, known paroxysmal AF, and permanent AF. All patients underwent transthoracic echocardiography, brain computed tomography scan, carotid/vertebral ultrasound, and continuous electrocardiographic monitoring...

In subjects with aortic regurgitation (AR) or mitral regurgitation (MR), transthoracic echocardiography (TTE) is recommended for surveillance. Few prospective studies have directly compared the ability of TTE and cardiac magnetic resonance (CMR) to predict clinical outcomes in AR and MR. We hypothesized that, given its higher reproducibility, CMR would predict the need for valve surgery or heart failure (HF) hospitalization better than TTE. Quantitative TTE and CMR were performed on the same day for 51 subjects: 29 with chronic AR and 22 with chronic, primary MR for quantification of valve regurgitation...

Transcatheter aortic valve implantation (TAVI) is the treatment of choice for inoperable and high-risk patients with severe aortic stenosis. Our objectives were to elucidate potential differences in clinical outcomes and safety between balloon-expandable versus self-expandable transcatheter heart valves (THV). We performed a retrospective cohort study of all transfemoral TAVI procedures in Ontario, Canada, from 2007 to 2013. Patients were categorized into either balloon-expandable or self-expandable THV groups...

Complications after transcatheter aortic valve implantation (TAVI) remain an important issue. This study aimed to evaluate the impact of systematic postprocedural multidetector computed tomography (MDCT) to detect subclinical complications after TAVI. From October 2013 to August 2015, a total of 135 patients who underwent transfemoral TAVI (n = 116) or transapical TAVI (n = 19) with Sapien XT and MDCT preprocedure and postprocedure were enrolled. Postprocedural MDCT findings were compared with the preprocedural MDCT findings...

Infective endocarditis is defined by a focus of infection within the heart and is a feared disease across the field of cardiology. It is frequently acquired in the health care setting, and more than one-half of cases now occur in patients without known heart disease. Despite optimal care, mortality approaches 30% at 1 year. The challenges posed by infective endocarditis are significant. It is heterogeneous in etiology, clinical manifestations, and course. Staphylococcus aureus, which has become the predominant causative organism in the developed world, leads to an aggressive form of the disease, often in vulnerable or elderly patient populations...

REVIEW

Although surgery was the mainstay of treatment for valvular heart disease, transcatheter valve therapies have grown exponentially over the past decade. Two types of artificial heart valve exist: mechanical heart valves (MHV), which are implanted surgically, and bioprosthetic heart valves (BHV), which can be implanted via a surgical or transcatheter approach. Whereas long-term anticoagulation is required to prevent thromboembolism after MHV replacement, its value in patients receiving BHVs is uncertain. Patients undergoing transcatheter BHV replacement are at risk for thromboembolism in the first few months, and recent data suggest that the risk continues thereafter...

Transcatheter aortic valve implantation (TAVI) is a rapidly evolving safe method with decreasing incidence of perioperative stroke. There is a void in literature concerning the impact of stroke after TAVI in predicting 30-day stroke-related mortality. The primary aim of this meta-analysis was to determine whether perioperative stroke increases risk of stroke-related mortality after TAVI. Online databases, using relevant keywords, and additional related records were searched to retrieve articles involving TAVI and stroke after TAVI...

Vascular access and closure remain a challenge in transcatheter aortic valve replacement (TAVR). This single-center study aimed to report the incidence, predictive factors, and clinical outcomes of access-related vascular injury and subsequent vascular intervention. During a 30-month period, 365 patients underwent TAVR and 333 patients (94%) were treated by true percutaneous transfemoral approach. Of this latter group, 83 patients (25%) had an access-related vascular injury that was managed by the use of a covered self-expanding stent (n = 49), balloon angioplasty (n = 33), or by surgical intervention (n = 1)...

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...

New-onset conduction disturbances are common after transcatheter aortic valve implantation (TAVI). The most common complication is left bundle branch block (LBBB). The clinical impact of new-onset LBBB after TAVI remains controversial. The aim of this study was to analyze the clinical impact of new-onset LBBB in terms of mortality and morbidity (need for pacemakers and admissions for heart failure) at long-term follow-up. From April 2008 to December 2014, 220 patients who had severe aortic stenosis were treated with the implantation of a CoreValve prosthesis...

Treatment for severe symptomatic aortic stenosis has changed significantly in recent years due to advances in transcatheter aortic valve replacement (TAVR). Recent studies with the CoreValve prosthesis have demonstrated superior results compared with surgical aortic valve replacement in patients at increased risk for surgery, but there are limited data on gender-related differences in patient characteristics and outcomes with this device. We compared baseline characteristics and clinical outcomes in women and men undergoing TAVR with the CoreValve prosthesis...

The objective of this study was to compare outcomes in women after surgical aortic valve replacement (SAVR) versus transcatheter aortic valve replacement (TAVR) using a self-expanding prosthesis in patients with severe aortic stenosis who were at high risk for SAVR. Although registries and meta-analyses have suggested that TAVR is of considerable benefit in women, perhaps even more so than in men, a rigorous evaluation of TAVR with a self-expanding valve versus SAVR in women from a randomized trial has not been performed...

This study was performed to assess the acute intraprocedural effects of transcatheter direct mitral annuloplasty using the Cardioband device on 3-dimensional (3D) anatomy of the mitral annulus. Of 45 patients with functional mitral regurgitation (MR) enrolled in a single arm, multicenter, prospective trial, 22 had complete pre- and post-implant 3D transesophageal echocardiography (TEE) images stored in native data format that allowed off-line 3D reconstruction. Images with the highest volume rate and best image quality were selected for analysis...

#19
REVIEW
Marie-Annick Clavel, Julien Magne, Philippe Pibarot
An important proportion of patients with aortic stenosis (AS) have a 'low-gradient' AS, i.e. a small aortic valve area (AVA <1.0 cm(2)) consistent with severe AS but a low mean transvalvular gradient (<40 mmHg) consistent with non-severe AS. The management of this subset of patients is particularly challenging because the AVA-gradient discrepancy raises uncertainty about the actual stenosis severity and thus about the indication for aortic valve replacement (AVR) if the patient has symptoms and/or left ventricular (LV) systolic dysfunction...

UNLABELLED: A 91-year-old man was admitted to our hospital with dyspnea and chest pain. His electrocardiogram showed ST-segment elevation in the V1-4 leads, and an emergency coronary angiogram revealed subtotal occlusion in the left descending coronary artery. A successful primary percutaneous coronary intervention was subsequently performed using aspiration thrombectomy and bare metal stent implantation. However, his hemodynamic condition deteriorated with severe pulmonary congestion...
