Intravascular Lithotripsy for Severe RVOT Calcification to Optimize Transcatheter Pulmonary Valve Replacement

JACC: Case Reports, 2023
The presence of severe right ventricular outflow tract calcification may preclude safe and effective transcatheter pulmonary valve replacement in patients with pulmonary allograft stenosis owing to the risk of conduit tear and suboptimal annular ...

Undiagnosed hypertrophic obstructive cardiomyopathy during transcatheter aortic valve replacement: a case report

Journal of Medical Case Reports, 2018
Background Transcatheter aortic valve replacement is indicated for severe symptomatic aortic stenosis in patients who have a very high or prohibitive surgical risk as assessed pre-procedurally by the Society of Thoracic Surgery Risk Score, EuroSCORE (II),

A rule-based method to model myocardial fiber orientation in cardiac biventricular geometries with outflow tracts [PDF]

arXiv, 2018
Rule-based methods are often used for assigning fiber orientation to cardiac anatomical models. However, existing methods have been developed using data mostly from the left ventricle. As a consequence, fiber information obtained from rule-based methods often does not match histological data in other areas of the heart such as the right ventricle ...

Emergent Cardiac Surgery After Transcatheter Structural Heart Procedures: Narrative Review

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Transcatheter structural heart procedures have become standard therapy for elderly patients with high surgical risk. Over time, these procedures have significantly increased worldwide, accompanied by a concomitant reduction of major complications, including those requiring emergent cardiac surgery (ECS).

Vector Field Streamline Clustering Framework for Brain Fiber Tract Segmentation [PDF]

arXiv, 2020
Brain fiber tracts are widely used in studying brain diseases, which may lead to a better understanding of how disease affects the brain. The segmentation of brain fiber tracts assumed enormous importance in disease analysis. In this paper, we propose a novel vector field streamline clustering framework for brain fiber tract segmentations.

Intramyocardial Hematoma After Percutaneous Coronary Intervention for Chronic Total Occlusion: Two Case Reports

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) is an extremely challenging procedure, with intramyocardial hematoma (IMH) being one of its rare yet severe complications. In this report, we detail two cases of IMH occurring during PCI for CTO, emphasizing the importance of avoiding catheter pressure entrapment and ...

Novel Techniques for Alcohol Septal Ablation in Hypertrophic Obstructive Cardiomyopathy With Complex Anatomy: A Case Series

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Alcohol septal ablation (ASA) is an established treatment for hypertrophic obstructive cardiomyopathy (HOCM). However, conventional techniques may be challenging in cases with complex septal branch anatomy, including hairpin curves, extremely small branches, and acute angle bifurcations.

Prevention of LVOT Obstruction by Device-Mediated Laceration of the Anterior Mitral Valve Leaflet During TMVR

JACC: Case Reports, 2023
Left ventricular outflow tract obstruction represents a life-threatening complication in patients undergoing transcatheter mitral valve replacement. Interventional approaches to prevent left ventricular outflow tract obstruction are complex and require ...

Preliminary experience with continuous right ventricular pressure and transesophageal echocardiography monitoring in orthotopic liver transplantation.

PLoS ONE, 2022
BackgroundDespite increasing attention in the cardiac anesthesiology literature, continuous measurement of right ventricular pressure using a pulmonary artery catheter has not been described in orthotopic liver transplantation, despite similarities in ...
