On Some Properties of $K$- type Block Matrices in the context of Complementarity Problem [PDF]

arXiv, 2021
In this article we introduce $K$-type block matrices which include two new classes of block matrices namely block triangular $K$-matrices and hidden block triangular $K$-matrices. We show that the solution of linear complementarity problem with $K$-type block matrices can be obtained by solving a linear programming problem.

Early genetic screening and cardiac intervention in patients with cardiomyopathies in a multidisciplinary clinic

ESC Heart Failure, EarlyView.
Abstract Aims Patients with cardiomyopathies are a heterogeneous group of patients who experience high morbidity and mortality. Early cardiac assessment and intervention with access to genetic counselling in a multidisciplinary Cardiomyopathy Clinic may improve outcomes and prevent progression to advanced heart failure.

Temporal profiling of M‐TEER‐related complications

ESC Heart Failure, EarlyView.
Abstract Aims Transcatheter edge‐to‐edge repair of the mitral valve (M‐TEER) is known for its low complication rates. However, the optimal level and duration of post‐procedural care remain unclear. This study aimed to identify the specific timeframe of post‐procedural complications following M‐TEER.

Amplatzer Septal Occluder-induced Transient Complete Atrioventricular Block

Journal of the Formosan Medical Association, 2007
Percutaneous transcatheter atrial septal defect (ASD) closure is a widely used technique that has replaced open-heart surgical closure in many centers. The most common implant is the Amplatzer septal occluder which seems to be a highly effective and safe

Clinical evaluation of nebulized verapamil in out‐patients with pulmonary hypertension secondary to chronic obstructive pulmonary disease

The Clinical Respiratory Journal, Volume 16, Issue 12, Page 802-811, December 2022., 2022
Single dose nebulized verapamil inhalation showed improvement in V/Q mismatch throught increase FVC. Nebulized verapamil inhalation improved gas exchanged and increased spO2. Nebulized verapamil inhalation for out‐patients with pulmonary hypertension secondary to chronic obstructive pulmonary disease improved spirometric parameter.

Atrioventricular block in coronary artery bypass surgery: perioperative predictors and impact on mortality

Brazilian Journal of Cardiovascular Surgery, 2015
Introduction:Disturbances of the cardiac conduction system are frequent in the postoperative period of coronary artery bypass surgery. They are mostly reversible and associated with some injury of the conduction tissue, caused by the ischemic heart ...

Cardiac magnetic resonance left atrioventricular coupling index as a prognostic tool in hypertrophic cardiomyopathy

ESC Heart Failure, EarlyView.
Abstract Aims A novel marker left atrioventricular coupling index (LACI) has been proved to be associated with cardiovascular events in patients without history of cardiovascular disease. However, the studies on cardiac magnetic resonance‐derived LACI in hypertrophic cardiomyopathy (HCM) patients are limited, and the prognostic value of LACI has still ...

Reversal of rocuronium‐induced intense neuromuscular blockade by sugammadex in Korean children: A pharmacokinetic and pharmacodynamic analysis

Clinical and Translational Science, Volume 16, Issue 1, Page 92-103, January 2023., 2023
Abstract Sugammadex, a selective antagonist of steroidal non‐depolarizing neuromuscular blocking agents, has been used in children in limited circumstances. However, neither pharmacokinetics (PKs) nor recovery profile of sugammadex for intense neuromuscular blockade reversal in children have been reported.

A note on $2\times 2$ block-diagonal preconditioning [PDF]

arXiv, 2020
For 2x2 block matrices, it is well-known that block-triangular or block-LDU preconditioners with an exact Schur complement (inverse) converge in at most two iterations for fixed-point or minimal-residual methods. Similarly, for saddle-point matrices with a zero (2,2)-block, block-diagonal preconditioners converge in at most three iterations for minimal-
