Transcatheter Aortic Valve Implantation: Insights into Clinical Complications [PDF]

, 2014
__Abstract__ Transcatheter Aortic Valve Implantation (TAVI) has emerged as a viable and safe treatment for patients with severe aortic stenosis (AS) who are considered ineligible or at prohibitive risk for Surgical Aortic Valve Replacement (SAVR)1–4.

Role of Echocardiography Before Transcatheter Aortic Valve Implantation (TAVI) [PDF]

, 2016
Aortic stenosis (AS) is the most common primary valve disorder in the elderly with an increasing prevalence; transcatheter aortic valve implantation (TAVI) has become an accepted alternative to surgical aortic valve replacement (AVR) in the high risk or ...

Isovolumic relaxation strain imaging is an accurate and sensitive approach for detection of active diastolic dysfunction: A preclinical study

Animal Models and Experimental Medicine, EarlyView.
A modified approach was developed to accurately identify the isovolumetric relaxation time (IVRT) using an apical three‐chamber view. Compared with conventional echocardiography, isovolumic relaxation strain imaging (IVSI) helps to detect the earlier alternations of diastolic function in transverse aortic constriction (TAC) mice.

Wireless blood pressure sensor implantation in sheep: A detailed technique

Animal Models and Experimental Medicine, EarlyView.
Twelve adult sheep underwent wireless blood pressure sensor implantation. The procedure lasted an average of 36 min, with mean systolic and diastolic blood pressures of 93 ± 6 and 65 ± 5 mmHg, respectively. This rapid, minimally invasive protocol is a powerful platform for cardiovascular device development.

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.

Macrophage‐targeted cerium‐tannic acid metal‐polyphenol framework nanoenzyme promotes in situ heart valves regeneration through adaptive immunomodulation

BMEMat, EarlyView.
A novel nanoenzyme based on cerium ions‐tannic acid metal‐polyphenol framework (FCT) has been developed and loaded onto DHVs for targeting M1 macrophages to reduce their ROS level and reprogram macrophage phenotype, thereby eliminating inflammation, promoting endothelialization and adaptive matrix remodeling of scaffolds, offering a promising strategy ...

TAVR in Male Patients With Large Aortic Valve Annuli: A Propensity‐Matched Analysis of Balloon‐Expandable Versus Self‐Expanding Valves

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Trans‐catheter aortic valve replacement (TAVR) in patients with large annuli poses procedural difficulties and possible complications. Aims We sought to compare the peri‐procedural and long‐term outcomes of patients with large annuli undergoing TAVR with self‐expanding (SEV) versus balloon‐expandable (BEV) valves.

Case Report: A case of transcatheter aortic valve replacement in a patient with a small aortic annulus using the Acurate Neo2

Frontiers in Cardiovascular Medicine
Small aortic annulus poses a major challenge in aortic valve replacement due to the increased risk of prosthesis–patient mismatch (PPM) and increased surgical risk.
