Incidence and Predictors of Acute Kidney Injury Following Transcatheter Aortic Valve Replacement: Role of Changing Definitions of Renal Function and Injury.

CONCLUSIONS: The incidence and risk factor associations for AKI post TAVR vary by definitions used. Decreased GFR at baseline by both MDRD and CKD-EPI and non-transfemoral approach were associated with an increased risk of AKI post TAVR. PMID: 31941833 [PubMed - as supplied by publisher]

Authors: Jiang Q, Wang Z, Guo J, Yu T, Zhang X, Hu S Abstract Objectives: We investigated whether the totally video-assisted thoracoscopic mitral valve surgery provides superior clinical outcomes and less inflammatory injury reaction compared with conventional sternotomy.Methods: A total of 504 consecutive patients admitted for mitral valve surgery from May 2014 through May 2019 in a single center were retrospectively analyzed according to two distinct procedure approach: the totally video-assisted thoracoscopic approach (group A, n = 127) and standard median sternotomy (group B, n = 377...

We describe a successful bioprosthetic annular stretching in a patient with severe prosthetic aortic valve stenosis from a degenerated 19-mm Mitroflow valve (Sorin Group USA Inc, Arvada, CO, USA). This technique allowed for implantation of a 23-mm Evolut-R Pro valve (Medtronic, Minneapolis, MN, USA) with significant improvement in hemodynamics after prosthetic annular stretching. We have also summarized other case series and case reports which have previously described similar techniques.

My understanding of the legality and propriety of hospital"advertising" in social media was rather vague but an article on this topic cleared away the cobwebs (see:Hospital Advertising). Below is an excerpt from it. It turns out to be legal but later in the post I will discuss why I think it's beneficial for healthcare consumers.While advertising by doctors and hospitals has been legal for 30 years, until recently, professional taboos discouraged the practice. Increasing economic pressures and changing cultural norms have led, however, to the demise of these informal proscriptions, and advertisements pro...

In this study, a 2D index relying on pre-procedural computed tomography (CT) data was developed to evaluate the risk of coronary obstruction during transcatheter aortic valve replacement (TAVR) procedures.

Recent high-resolution CT studies after transcatheter aortic valve insertion (TAVI) have reported high prevalence of subclinical valve thrombosis (SCVT), potentially contributing to increased risk of late stroke. We aimed to investigate SCVT after TAVI patients with focus on prevalence, predisposing factors, management, and potential sequelae.

Long-term outcomes of aortic valve replacement (AVR) are worse in patients with tricuspid regurgitation (TR) but the impact of concomitant tricuspid valve intervention remains unclear. The purpose of this study was to determine the effect of tricuspid intervention in patients with TR undergoing AVR.

Congenital heart valve disease has life-threatening consequences that warrant early valve replacement; however, the development of a growth-accommodating prosthetic valve has remained elusive. Thousands of children continue to face multiple high-risk open-heart operations to replace valves that they have outgrown. Here, we demonstrate a biomimetic prosthetic valve that is geometrically adaptable to accommodate somatic growth and structural asymmetries within the heart. Inspired by the human venous valve, whose geometry is optimized to preserve functionality across a wide range of constantly varying volume loads and diamete...

How much importance should the cardiac surgeon place on the dynamic, intraoperative transesophageal echo (TEE) information in executing an excellent operation? Perhaps this seems almost a silly question. After all, no one would question the importance of TEE in assessing adequacy of a mitral valve repair or left ventricular outflow tract resection or aortic valve repair. So, why are the completely intuitive findings in the current paper, e.g., that obvious residual right ventricular outflow tract obstruction (RVOTO) in the acute, intraoperative TEE after tetralogy of Fallot repair (TOF), important enough to add to the surg...

The objective of this study was to assess imaging predictors of mitral regurgitation (MR) improvement and to evaluate the impact of MR regression on long-term outcome in patients undergoing transcatheter aortic valve replacement (TAVR).BackgroundConcomitant MR is a frequent finding in patients with severe aortic stenosis but usually left untreated at the time of TAVR.MethodsMitral regurgitation was graded by transthoracic echocardiography before and after TAVR in 677 consecutive patients with severe aortic stenosis. 2-year mortality was related to the degree of baseline and discharge MR. Morphological echo analysis was per...
