REVIEW
Takahiro Shiota
Catheter-based treatment of valvular heart disease, such as transvalvular aortic valve replacement (TAVR) or mitral clip procedure, has been increasingly accepted as a treatment choice for the past several years. Such new treatment options have been changing the management of patients with valvular heart disease drastically while socio-economic factors regarding their application need to be taken into consideration. The use of echocardiography, including transesophageal echocardiography (TEE), for such catheter-based treatments is essential for the success of the procedures...

OBJECTIVES: Describe changes in measures of right ventricular (RV) function in patients treated for aortic stenosis using open-chest surgery (SAVR) or transcatheter treatment (TAVR). METHODS: Patients in the Nordic Aortic Valve Intervention (NOTION) trial were randomized 1:1 to TAVR (n = 114) or SAVR (n = 106). Echocardiography was performed at baseline and 3 and 12 months post-procedure. Tricuspid annular plane systolic excursion (TAPSE) and right ventricular fractional area change (RVFAC) were used as measures of longitudinal and transverse RV contraction...

OBJECTIVES: To evaluate the role of balloon annular sizing in transcatheter aortic valve replacement (TAVR). BACKGROUND: Multidetector cardiac computed tomography (MDCT) is the gold standard for aortic annular sizing in TAVR. Balloon sizing is increasingly used in patients with borderline annular size and severe calcification. A comparison between these two techniques is needed. METHODS: We retrospectively compared baseline characteristics and 30-day outcomes of patients undergoing balloon-expandable TAVR using annular MDCT or balloon sizing...

Transcatheter aortic valve replacement (TAVR) is an increasingly used alternative to surgical aortic valve replacement in patients with severe aortic stenosis and prohibitive perioperative risk. Several studies have shown an improved clinical outcome and lower rate of complications with TAVR in this patient population. Furthermore, TAVR has shown promising results in patients at elevated risk from surgical aortic valve replacement. Because of the endovascular nature of this technique, comprehensive preprocedural assessment of the aortic root and vascular access path is crucial...

INTRODUCTION: Left bundle branch block (LBBB) is a known complication of transcatheter aortic valve replacement (TAVR) and has been shown to predict worsened outcomes in TAVR patients. A regional longitudinal strain pattern, termed the "classic" pattern of left ventricular (LV) dyssynchrony, which is thought to be due to LBBB, is highly predictive of response to cardiac resynchronization therapy. Whether LBBB causes this "classic" pattern is not known. METHODS: We retrospectively studied patients undergoing TAVR who also underwent pre- and post-TAVR strain analysis to determine if the "classic" pattern arose in those who developed TAVR-induced true LBBB...

OBJECTIVE: Low flow (LF), defined as stroke volume index (SVi) <35 mL/m(2), prior to the procedure has been recently identified as a powerful independent predictor of early and late mortality in patients undergoing transcatheter aortic valve replacement (TAVR). The objectives of this study were to determine the evolution of SVi following TAVR and to assess the determinants and impact on mortality of early postprocedural SVi (EP-SVi). METHODS: We retrospectively analysed the clinical, Doppler echocardiographic and outcome data prospectively collected in 255 patients who underwent TAVR...

INTRODUCTION: Calcific aortic stenosis (AS) is a common valvular disease among the elderly. Often, AS leads to left ventricular hypertrophy (LVH) and symptoms of heart failure. Severe AS can be treated by transcatheter aortic valve replacement (TAVR). Previous studies have shown that electrocardiogram (ECG) criteria for LVH correlate poorly with left ventricular mass (LVM) in echocardiography. However, such correlations have not been studied in TAVR patients. AIMS: To evaluate ECG LVH criteria as a method of diagnosing and quantifying LVH in patients with AS undergoing TAVR...

Older patients suffering severe heart failure related to aortic stenosis (AS) undergo transcatheter aortic valve replacement (TAVR), owing to their high surgical risk. The diagnosis is made based on echocardiographic examination, but may require a multimodality imaging approach in patients with low gradients. In severely decompensated heart failure or cardiogenic shock, rescue percutaneous balloon aortic valvuloplasty as a bridge to TAVR seems reasonable. Emergent TAVR has been reported. Efforts should be made to avoid late diagnosis or referring patients with severe AS to offer them timely interventions, reduce the risk of TAVR, and predict whether left ventricular function will improve...
