Transcatheter aortic valve implantation: predictors of procedural success—the Siegburg-Bern experience [PDF]

, 2017
Aims The purpose of the present analysis was to identify predictors of procedural success of percutaneous transcatheter aortic valve implantation (TAVI). Methods and results We prospectively assessed in-hospital outcome of patients undergoing TAVI at two

Targeted 2‐Deoxy‐D‐Ribose Delivery by Biomimetic Nanoplatform Activates EGFR for Accelerated Heart Valve Endothelialization

Advanced Science, EarlyView.
This study develops a biomimetic nanoplatform using erythrocyte membrane‐camouflaged, CD144 antibody‐functionalized nanoparticles to deliver 2‐deoxy‐D‐ribose (2dDR). This system promotes heart valve endothelialization by enhancing endothelial cell migration and proliferation via EGFR activation, while improving hemocompatibility.

Transcatheter aortic valve implantation in failed bioprosthetic surgical valves. [PDF]

, 2014
IMPORTANCE: Owing to a considerable shift toward bioprosthesis implantation rather than mechanical valves, it is expected that patients will increasingly present with degenerated bioprostheses in the next few years.

The use of transgenic animals for xenotransplantation: An update

Animal Models and Experimental Medicine, EarlyView.
One way to produce genetically modified pigs is to use somatic cell nuclear transfer (SCNT). This procedure involves removing the metaphase plate from a mature oocyte using micromanipulation and then transferring the modified nucleus from the donor somatic cell to the oocyte.

Transcatheter Aortic Valve Implantation in Alkaptonuria-Аssociated Severe Aortic Stenosis: A 2.5-Year Follow-Up Case Report and Literature Review

Life
Introduction: Alkaptonuria is an autosomal-recessive disorder affecting the metabolism of tyrosine and phenylalanine which results in accumulation of homogentisic acid in connective tissues.

A Streamline Strategy for Indication and Length of Telemetry Monitoring After TAVR

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Both indication and length of ECG telemetry monitoring (TM) after transcatheter aortic valve replacement (TAVR) are not well defined. Aims We hypothesize that a targeted strategy for monitoring conductive disorders (CD) post‐TAVR can reduce the need and duration of in‐hospital TM without compromising safety. Methods We prospectively

Aortic Valve Replacement with a Conventional Stented Bioprosthesis versus Sutureless Bioprosthesis: a Study of 763 Patients

Brazilian Journal of Cardiovascular Surgery
Objective: The aim of this retrospective study was to compare early postoperative outcomes after aortic valve replacement (AVR) with sutureless bioprostheses and conventional stented bioprostheses implanted through median sternotomy.

Hybrid debranching and TEVAR of the aortic arch off-pump, in re-do patients with complicated chronic type-A aortic dissections : a critical report [PDF]

, 2013
Background: Patients suffering from acute type A aortic dissection undergo replacement of the ascending aorta, the proximal hemiarch or complete aortic arch, depending on the extent of the individual pathology.

Conversion to Cardiac Surgery During Elective and Urgent Transcatheter Aortic Valve Implantation: A Systematic Review and Meta‐Analysis

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Transcatheter aortic valve implantation (TAVI) has become an established treatment for severe aortic stenosis. However, the need for unplanned conversion to cardiac surgery (CS) during TAVI remains an infrequent but critical event. It is unclear whether this risk is higher in patients undergoing urgent procedures.
