Safety of permanent pacemaker implantation: a prospective study [PDF]

, 2019
Although pacemaker implantation is considered to be low risk, it is not exempt from complications and technical failures during the procedure, both in the short and long term, and the complications that such patients may present remain unknown.

Synchronization of the cardiac pacemaker model with delayed pulse-coupling [PDF]

arXiv, 2011
We consider the integrate-and-fire model of the cardiac pacemaker with delayed pulsatile coupling. Sufficient conditions of synchronization are obtained for identical and non-identical oscillators.

Cardiac MR Image Segmentation Techniques: an overview [PDF]

arXiv, 2015
Broadly speaking, the objective in cardiac image segmentation is to delineate the outer and inner walls of the heart to segment out either the entire or parts of the organ boundaries. This paper will focus on MR images as they are the most widely used in cardiac segmentation -- as a result of the accurate morphological information and better soft ...

Learning Directional Feature Maps for Cardiac MRI Segmentation [PDF]

arXiv, 2020
Cardiac MRI segmentation plays a crucial role in clinical diagnosis for evaluating personalized cardiac performance parameters. Due to the indistinct boundaries and heterogeneous intensity distributions in the cardiac MRI, most existing methods still suffer from two aspects of challenges: inter-class indistinction and intra-class inconsistency.

Acute Idiopathic Hemorrhagic Pericarditis with Cardiac Tamponade as the Initial Presentation of Acquired Immune Deficiency Syndrome [PDF]

, 2010
This paper presents a case of cardiac tamponade with idiopathic hemorrhagic pericarditis as the initial symptom of human immunodeficiency virus (HIV) infection. A 29-year-old male came to the emergency room with a sudden onset of dizziness. Upon arrival,

Anatomy-Aware Cardiac Motion Estimation [PDF]

arXiv, 2020
Cardiac motion estimation is critical to the assessment of cardiac function. Myocardium feature tracking (FT) can directly estimate cardiac motion from cine MRI, which requires no special scanning procedure. However, current deep learning-based FT methods may result in unrealistic myocardium shapes since the learning is solely guided by image ...

Feasibility of diagnosis of postcardiotomy tamponade by miniaturized transesophageal echocardiography. [PDF]

, 2014
BACKGROUND: Pericardial tamponade after cardiac surgery is a critical diagnosis that can be difficult to diagnose using conventional cardiac monitoring.

Magnetic Signature of Thermo-Electric Cardiac Dynamics [PDF]

Physical Review E, 111, 2025, L012401
Developing new methods for predicting electromagnetic instabilities in cardiac activity is of primary importance. However, we still need a comprehensive view of the heart's magnetic activity at the tissue scale. To fill this gap, we present a model of soft active matter, including thermo-electric coupling, suitably modified to reproduce cardiac ...

Outcomes of Cardiac Tamponade Post-Transcatheter Aortic Valve Replacement: Results From a Tertiary Cardiac Center

Structural Heart
Background: Cardiac tamponade is a rare but potentially lethal complication of transcatheter aortic valve replacement (TAVR). There is paucity of evidence assessing the incidence and outcomes of patients with cardiac tamponade after TAVR.

Pericardial effusion and outcome in children at a Tertiary Hospital in North-Western Nigeria: A 2-year retrospective review

Research in Cardiovascular Medicine, 2019
Background: Pericardial effusion may culminate in cardiac tamponade which could be fatal. This study aims to describe the prevalence of cardiac tamponade, with the etiology, and outcome of childhood pericardial effusion at Aminu Kano Teaching Hospital ...
