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 ...

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.

High-Resolution, Three-Dimensional Reconstruction of the Outflow Tract Demonstrates Segmental Differences in Cleared Eyes [PDF]
Purpose: The rate of conventional aqueous humor outflow is the highest nasally. We hypothesized that this is reflected in regionally different outflow structures and analyzed the entire limbus by high-resolution, full-thickness ribbon-scanning confocal microscopy (RSCM).

Combined tract segmentation and orientation mapping for bundle-specific tractography [PDF]
While the major white matter tracts are of great interest to numerous studies in neuroscience and medicine, their manual dissection in larger cohorts from diffusion MRI tractograms is time-consuming, requires expert knowledge and is hard to reproduce. In previous work we presented tract orientation mapping (TOM) as a novel concept for bundle-specific ...

Three-dimensional echocardiography and 2D-3D speckle tracking imaging in chronic pulmonary hypertension. diagnostic accuracy in detecting hemodynamic signs of RV failure [PDF]
Background and objective. Our aim was to compare three-dimensional (3D) and 2D and 3D speckle tracking (2D-STE, 3D-STE) echocardiographic parameters with conventional right ventricular (RV) indexes in patients with chronic pulmonary hypertension (PH ...

Right ventricular outflow tract aneurysm with thrombus [PDF]
Right ventricular outflow tract (RVOT) aneurysm is a known complication of tetralogy of Fallot repair when a ventriculotomy is done. It leads to RV dysfunction and may require re-operation. We describe a rare instance of a patient who developed an RVOT aneurysm after trans-ventricular repair of tetralogy of Fallot, which was complicated with the ...

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 Novel Mathematical/Numerical Formula for Assessing Right Ventricular Torsion Using Echocardiographic Imaging [PDF]
Recently, the ventricular torsional parameters have received special attention because of their significant role in the ventricular systolic and diastolic function. Right ventricular (RV) rotational deformation is a sensitive index for RV performance but difficult to measure.

ABSTRACT Background Little is known about stroke volume index (SVi) change and its prognostic implication in patients with low‐flow aortic stenosis (AS) undergoing aortic valve replacement (AVR) and conflicting results are present in literature. The aim of this study was to evaluate the postoperative change in SVi and its impact on outcomes in patients
