Hybrid Transcatheter Pulmonary Valve Replacement With SAPIEN S3 Following Right Ventricular Outflow Tract Reduction Using Tricuspid Annuloplasty Rings

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT We describe a novel variation of hybrid TPVR using a tricuspid annuloplasty ring which can be considered for patients with very large RVOT, short pulmonary artery, and limited vascular access and to avoid the risk of cardiopulmonary bypass. The utilization of Carpentier‐Edwards Physio Tricuspid annuloplasty ring can reduce the size of the RVOT

A deep learning approach to using wearable seismocardiography (SCG) for diagnosing aortic valve stenosis and predicting aortic hemodynamics obtained by 4D flow MRI [PDF]

arXiv, 2023
In this paper, we explored the use of deep learning for the prediction of aortic flow metrics obtained using 4D flow MRI using wearable seismocardiography (SCG) devices. 4D flow MRI provides a comprehensive assessment of cardiovascular hemodynamics, but it is costly and time-consuming.

An echocardiographic comparison of sutureless and conventional aortic valve replacement : a matched case-control study [PDF]

, 2018
Background: Patients at a high operative risk for conventional aortic valve replacement (AVR) may be offered sutureless valve implantation. Sutureless valves resemble conventional valves but incorporate an anchoring mechanism without using annular ...

Pressure‐Wire Guided Hybrid Branch Pulmonary Artery Band Placement for Palliation of Single Ventricle and Critical Congenital Cardiac Lesions

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Historically, bilateral pulmonary artery band (PAB) placement was guided by pulmonary blood flow surrogates including systemic blood pressure (BP) and arterial saturation. These metrics alone may result in suboptimal bPAB placement.

Continuation Versus Interruption of Oral Anticoagulation During TAVI: A Systematic Review and Meta‐Analysis Oral Anticoagulation Management in TAVI

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Patients undergoing transcatheter aortic valve implantation (TAVI) often require long‐term oral anticoagulation (OAC), but it is unclear whether to continue or interrupt OAC during the procedure. This meta‐analysis compares clinical outcomes of continuing versus interrupting OAC during TAVI.

Transcatheter and surgical aortic valve replacement in patients with left ventricular dysfunction

Journal of Cardiothoracic Surgery, 2022
Background Patients with severe aortic stenosis and left ventricular systolic dysfunction have a poor prognosis, and this may result in inferior survival also after aortic valve replacement.

Gradient Boosting on Decision Trees for Mortality Prediction in Transcatheter Aortic Valve Implantation [PDF]

arXiv, 2020
Current prognostic risk scores in cardiac surgery are based on statistics and do not yet benefit from machine learning. Statistical predictors are not robust enough to correctly identify patients who would benefit from Transcatheter Aortic Valve Implantation (TAVI).

Effects of stenotic aortic valve on the left heart hemodynamics: a fluid-structure-electrophysiology approach [PDF]

arXiv, 2021
The aortic valve is a three-leaflet passive structure that, driven by pressure differences between the left ventricle and the aorta, opens and closes during the heartbeat to ensure the correct stream direction and flow rate. In elderly individuals or because of particular pathologies, the valve leaflets can stiffen thus impairing the valve functioning ...

Material transport in the left ventricle with aortic valve regurgitation [PDF]

Physical Review Fluids, 3(11), 113101 (2018), 2018
This experimental in vitro work investigates material transport properties in a model left ventricle in the case of aortic regurgitation, a valvular disease characterized by a leaking aortic valve and consequently double-jet filling within the elastic left ventricular geometry.

Risk factors for paravalvular leak after transcatheter aortic valve replacement [PDF]

, 2019
Objective. To assess risk factors for paravalvular leak (PVL) after transcatheter aortic valve implantation (TAVI) in a large single-center cohort, including measurement of aortic valve calcification using a reproducible method. Methods.
