Role of imaging in third aortic valve implantation: TAV-in-TAV-in-SAV. [PDF]

Int J Cardiovasc Imaging
Abstract Coronary obstruction remains a primary concern for redo transcatheter aortic valve implantation (TAVI) due to supra-annular leaflets. Hereby, we present two valve-in-valve-in-valve cases, initially incorporating a surgical valve implanted to clarify our concept that the surgical valve serves to safeguard against the coronary ostium ...

Associations between cardio-ankle vascular index score, an indicator of arteriosclerosis and aortic volume and hemodynamic parameters using four-dimensional magnetic resonance imaging [PDF]

BMC Cardiovascular Disorders
Backgroud The cardio-ankle vascular index (CAVI) is a noninvasive measure of arterial stiffness, but it does not assess blood flow or aortic shape. Four-dimensional (4D) magnetic resonance imaging (MRI) has emerged as a promising tool for evaluating ...

A Case of CABG in a Patient with High Risk of Coronary Obstruction during TAV-in-TAV. [PDF]

Ann Thorac Cardiovasc Surg
A 94-year-old man who underwent transcatheter aortic valve (TAV) replacement 6 years ago was admitted because of exertional dyspnea. Transthoracic echocardiography revealed severe aortic regurgitation owing to TAV dysfunction. The patient was considered to have a high risk of occlusion of the sinus of Valsalva during TAV-in-TAV. Therefore, we performed

Revisiting the SURPLUS Procedure—A Hybrid Solution to the Complex Aortic Root [PDF]

Annals of Thoracic Surgery Short Reports
Valve-in-valve transcatheter aortic valve (TAV) replacement (TAVR) is becoming increasingly more common in patients with bioprosthetic valve failure. However, solutions for high-risk patients with prior TAVR deployment remain challenging, and TAV-in-TAV ...

Differences in Severity and Prognosis Between Bicuspid and Tricuspid Severe Aortic Stenosis [PDF]

JACC: Advances
Background: Bicuspid aortic valve (BAV) often leads to aortic stenosis (AS). However, current severity assessment and treatment strategies do not differentiate between BAV and tricuspid aortic valve (TAV) patients.

Comparative evaluation of coronary disease burden: bicuspid valve disease is not atheroprotective

Open Heart, 2021
Objective Bicuspid aortic valve (BAV) has been associated with less atherosclerosis as compared with tricuspid aortic valve (TAV) patients. It, however, remains unclear whether this reflects the older age of TAV patients and/or accumulation of ...
