Effectiveness of Pre-TAVR CTA as a Screening Tool for Significant CAD Before TAVR

, 2023
Computed tomography angiography (CTA) and invasive coronary angiography (ICA) are routinely performed before transcatheter aortic valve replacement (TAVR) to assess aortic root anatomy and screen for coronary artery disease (CAD), respectively.

Productivity, Stability, and Adaptability of Onion Genotypes Using Additive Main Effects and Multiplicative Interaction and Mixed‐Model Analysis

New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 4, December 2026.
Onion (Allium cepa L.) is a vegetable crop of both nutritional and medicinal importance. Bulb development is strongly dependent on the interaction between photoperiod and temperature, which drives the adaptation of genotypes to specific growing conditions.

Room Considerations with TAVR [PDF]

Methodist DeBakey Cardiovascular Journal, 2012
While transcatheter aortic valve replacement is considered a viable alternative to traditional surgery for patients with critical aortic stenosis, it is still a cardiac surgical procedure with a steep learning curve. Space consideration is a key aspect of the procedure's success.

Brassinosteroid Enhances Thermotolerance by Improving Photosynthesis and Membrane Stability Under Reproductive‐Stage Heat Stress in KDML105 Rice (Oryza sativa L.)

Journal of Agronomy and Crop Science, Volume 212, Issue 6, November 2026.
ABSTRACT Brassinosteroids (BRs) are plant steroid hormones known to enhance tolerance to abiotic stress, including heat stress (HT). This study investigated the effects of foliar application of BRs (0, 0.05, 0.1, and 0.5 nM) on the physiological performance and yield of the tropical photosensitive rice cultivar KDML105 at the reproductive stage under ...

New Model for the Assessment of Transcatheter Aortic Valve Replacement Devices in Sheep

Journal of Investigative Surgery, 2022
Background Transcatheter aortic valve replacement (TAVR) is an effective therapy in treating high-risk patients suffering from aortic stenosis. Animal models used to evaluate safety and efficacy of TAVR devices prior to clinical use lack a stenotic ...

Aortic valve disease: Novel animal models for advancing our understanding of the underlying mechanisms

Animal Models and Experimental Medicine, Volume 9, Issue 10, Page 1964-1981, October 2026.
Due to the complex pathophysiology of aortic valve disease (AVD) and the resulting lack of effective pharmacotherapy, existing animal models are valuable research tools, but each has its own strengths and limitations. This review systematically surveys the major AVD models, compares their induction methods, pathological features, advantages and ...

Percutaneous Transaxillary Access for Large‐Bore Cardiovascular Interventions: Evidence, Technique, and Complication Management

Catheterization and Cardiovascular Interventions, Volume 108, Issue 4, Page 1186-1197, October 1, 2026.
ABSTRACT Percutaneous transaxillary access is an established alternative to transfemoral large‐bore arterial access for transcatheter structural heart interventions and mechanical circulatory support (MCS). Although useful for overcoming hostile iliofemoral anatomy and providing prolonged support and patient mobilization in case of MCS, the axillary ...

TAVR-in-TAVR in Surgical Valve for Recurrence of Failed Bioprosthesis

JACC: Case Reports
We present a case of a transcatheter aortic valve implantation in patient with a recurrent aortic bioprosthetic valve failure. Concerns about left main coronary artery occlusion led to a protective stent placement, ensuring successful Evolut R implantation.

Total Muscle Area and Visceral Adipose Tissue Measurements for Frailty Assessment in TAVR Patients. [PDF]

Background: Transcatheter aortic valve replacement (TAVR) is a treatment option for severe aortic valve stenosis. Pre-TAVR assessments, extending beyond anatomy, include evaluating frailty. Potential frailty parameters in pre-TAVR computed tomography (CT)
