BACKGROUND: Non-invasive cardiac imaging allows detection of cardiac amyloidosis (CA) in patients with aortic stenosis (AS). Our objective was to estimate the prevalence of clinically suspected CA in patients with moderate and severe AS referred for cardiovascular magnetic resonance (CMR) in age and gender categories, and assess associations between AS-CA and all-cause mortality. METHODS: We retrospectively identified consecutive AS patients defined by echocardiography referred for further CMR assessment of valvular, myocardial, and aortic disease...

OBJECTIVES: The study aim was to assess the effect of hourglass-shaped V8 and TAV8 balloons (InterValve, Inc) on aortic valve area (AVA) and other outcomes in patients with severe aortic stenosis undergoing balloon aortic valvuloplasty (BAV). BAV has re-emerged with transcatheter therapy. Cylindrical balloons have been the device of choice despite limitations. The hourglass-shaped balloons, with shorter, broader segments separated by a narrowed waist, permit enhanced fixation and better leaflet opening without annular or sinotubular compromise...

Bioprosthesis thrombosis after transcatheter aortic valve replacement (TAVR) raised concerns about further clinical events. We report the case of a patient who suffered acute myocardial infarction (AMI) after TAVR for 3 years. Thrombosis was confirmed in the right coronary sinus of Valsalva by transthoracic echocardiography. Coronary angiography demonstrated the ostium of the right coronary artery was occluded. As an attempt to perform percutaneous coronary intervention (PCI) was unsuccessful, long-term therapeutic anticoagulation with warfarin was undertaken...

BACKGROUND: In transcatheter aortic valve replacement (TAVR), multi-detector row computed tomography (MDCT) is currently the standard imaging modality for correct prosthesis sizing, despite risks of radiation and contrast-induced renal injury. Three-dimensional (3D) transesophageal echocardiography (TEE) has been proposed as a potential alternative imaging technique, and recently, automated 3D transesophageal echocardiographic software (Aortic Valve Navigator [AVN], an unreleased prototype from Philips) has been developed for assessment of the aortic annulus and root...

This case report is about an 85-year-old woman with bicuspid aortic stenosis (AS). Although preoperative multimodality imaging showed challenging anatomical aspects, transcatheter aortic valve replacement (TAVR) was selected to be performed as a less invasive alternative treatment approach, owing to her comorbidity. Postoperative transesophageal echocardiography and multidetector-row computed tomography revealed the presence of "locked-in leaflet" caused by stent distortion due to pinching by calcified native leaflets, with nodular calcification preventing the full expansion of the valve, which resulted in moderate perivalvular leakage...

Intravascular hemolysis (IVH) has been identified in patients with surgical prosthetic valves, but few have been reported after transcatheter aortic valve implantation (TAVI). We conducted a prospective analysis of 64 TAVI patients. The hemolysis profiles were collected at baseline and 6 months after TAVI. The echocardiography was performed at baseline and 6 months after TAVI. There are 14 patients (21.9%) with IVH before and 24(37.5%) after TAVI. The serum haptoglobin values before and 6 months after TAVI are 126...

Introduction: After early successful experience with transcatheter aortic valve replacement (TAVR), concept of transcatheter implantation of a new valve within a failing bioprosthetic valve emerged. Valve-in-valve (ViV) implantation seems to be a simpler option for high risk surgical patients. Methods: We performed five ViV procedures in different valve positions. We included patients with failing bioprosthetic valves with high surgical risk due to concomitant comorbidities. We performed 2 transapical ViV procedures for failing mitral bioprosthetic valves, 1 transfemoral procedure for failing pulmonary valve and 2 transfemoral ViV implantation for failing tricuspid bioprosthetic valves...

OBJECTIVES: We sought to assess angiographic, echocardiographic and hemodynamic grading of paravalvular leakage (PVL) after transcatheter aortic valve implantation (TAVI) with respect to prediction of 1-year mortality. BACKGROUND: Meaningful criteria for the severity of PVL are needed to allow intraprocedural guidance and patient management after TAVI. METHODS: We pooled the prospective TAVI databases of 2 German centers. During TAVI, PVL was assessed angiographically and by the aortic regurgitation index (ARI)...

Aortic stenosis is a common valvular condition with increasing prevalence in aging populations. When severe and symptomatic, the downstream prognosis is poor without surgical or transcatheter aortic valve replacement. Transcatheter aortic valve replacement is now considered a viable alternative to surgical aortic valve replacement in patients considered high and intermediate risk for surgery. Pre-intervention imaging with echocardiography and CT are essential for procedure planning and device selection to help optimize clinical outcomes with MR angiography playing largely a complementary role...

BACKGROUND: While transcatheter aortic valve implantation (TAVI) has traditionally been supported intraprocedurally by transoesophageal echocardiography (TOE), transthoracic echocardiography (TTE) is increasingly being used. We evaluated echocardiographic imaging characteristics and clinical outcomes in patients who underwent TTE during TAVI (TTE-TAVI). METHODS AND RESULTS: A select team of dedicated sonographers and interventional echocardiographers performed TTE-TAVI in 278 patients, all of whom underwent TAVI through transfemoral access...

Accurate aortic annulus sizing is key for selection of appropriate transcatheter aortic valve implantation (TAVI) prosthesis size. The present study compared novel automated 3-dimensional (3D) transesophageal echocardiography (TEE) software and multidetector row computed tomography (MDCT) for aortic annulus sizing and investigated the influence of the quantity of aortic valve calcium (AVC) on the selection of TAVI prosthesis size. A total of 83 patients with severe aortic stenosis undergoing TAVI were evaluated...

Aorto-atrial fistulas are a relatively rare, but potentially life-threatening condition, where an anomalous connection forms between the aortic structures and the cardiac atria. Aorto-atrial fistulas are most often the result of an underlying condition concerning the cardiac structures. It may be congenital, secondary to conditions such as aortic dissection, infective endocarditis, or valve replacement, or iatrogenic in nature. Secondary causes incite local deterioration of cardiac wall integrity leading to formation of fistulous connections, while iatrogenic causes are more traumatic in nature...

This report concerns an 83-year-old woman with aortic stenosis (AS) who had a history of repetitive hospitalization due to decompensated heart failure. Although her clinical history was compatible with significant AS, findings for aortic valve area, hemodynamics, and valvular calcium burden were discrepant. Multiplanar reconstruction images revealed the membranous structures attached to a subcommissural lesion, which resulted in severe stenosis. The patient had a favorable clinical course after transcatheter aortic valve replacement...

Omar K Khalique, Rebecca T Hahn
PURPOSE OF REVIEW: Transcatheter valvular interventions have increased in importance and utility for surgical valve repair and replacement. Cardiac imaging is the most crucial aspect of procedural planning and guidance. Echocardiography is a widely used, portable, and dynamic imaging modality used for many of these interventions. This review will summarize the role echocardiography in structural heart valvular interventions. RECENT FINDINGS: Intraprocedural echocardiographic guidance has been a mainstay of structural heart interventions...

AIMS: The XELTIS aortic valve leaflets are made from a bioabsorbable supramolecular polymer that guides the tissue to restoring itself. It is mounted on a self-expandable nitinol frame that includes three feelers and a native leaflet clipping mechanism. We sought to investigate the acute valve performance in a preclinical setting. METHODS AND RESULTS: In 33 sheep, 26 mm XELTIS aortic valve were transapically implanted in a 23 mm native annulus. Aortography (analysable, n=28) and echocardiography (analysable, n=20) were acquired immediately after implantation of the XELTIS aortic valve to assess the acute device performance...

OBJECTIVES: To describe patients with severe symptomatic aortic stenosis with normal flow and low gradients and determine whether they benefit from intervention. BACKGROUND: Severe symptomatic aortic stenosis is a progressive disease with high mortality. Although surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR) are indicated for patients with high gradients (>40 mm Hg) or low gradients due to low flow, the approach for patients with normal flow and low gradients is poorly defined...

A 80-year-old man was admitted to catheterization room for an acute infero-lateral ST-elevation myocardial infarction (STEMI). Coronary angiography showed a thrombotic occlusion of the second left marginal branch, and normal other coronary arteries. The thrombo-embolic mechanism of the STEMI, and the infectious context in this patient who had had a transcatheter aortic valve implantation (TAVI) two months earlier, led us to suspect a bioprosthesis endocarditis. It was confirmed by transthoracic and transoesophageal echocardiography, which showed an aortic-mitral curtain abscess and aortic bioprosthesis vegetations, associated to Enterococcus faecalis bacteriemia...

OBJECTIVES: The transapical approach provides concurrent surgical access to the mitral and the aortic valves, the root of the aorta and the left atrium. We previously showed the feasibility of transapical cardioscopic (TAC) surgery in a non-survival porcine model. However, reproducibility and feasibility of ring implantation using TAC have not been reported. Therefore, in this study, we hypothesized that implantation of a mitral annuloplasty ring can be feasibly and safely carried out endoscopically via the apex of the heart...
