In vivo dose measurement using TLDs and MOSFET dosimeters for cardiac radiosurgery. [PDF]

, 2012
In vivo measurements were made of the dose delivered to animal models in an effort to develop a method for treating cardiac arrhythmia using radiation. This treatment would replace RF energy (currently used to create cardiac scar) with ionizing radiation.

Anomalous origin of the right coronary artery from the left coronary sinus with an interarterial course: subtypes and clinical importance.

Radiology, 2012
PURPOSE To classify anomalous origins of the right coronary artery (RCA) from the left coronary sinus (AORL) with an interarterial course into two subtypes and to evaluate the clinical importance of each.

Safety and Efficacy of a Plug‐Based Vascular Closure Device After Percutaneous Microaxial Flow Pump in the Treatment of Complex and High‐Risk Indicated Patients

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Femoral large‐bore vascular access is an important and constantly increasing technique in interventional treatment. Temporary circulatory support in complex and high‐risk indicated patients (CHIP) presents a challenge in terms of postinterventional access site closure.

Fused Segmentation of Geometric Models for Myocardium and Coronary Artery via Medial Axis [PDF]

arXiv, 2017
Coronary arteries and their branches supply blood to myocardium. The obstruction of coronary arteries results in significant loss of myocardium, called acute myocardial infarction, and the number one cause of death globally. Hence, quantification of the regional amount of heart muscle subtended by obstructed coronary arteries is of critical value in ...

Supervised Contrastive Learning to Classify Paranasal Anomalies in the Maxillary Sinus [PDF]

arXiv, 2022
Using deep learning techniques, anomalies in the paranasal sinus system can be detected automatically in MRI images and can be further analyzed and classified based on their volume, shape and other parameters like local contrast. However due to limited training data, traditional supervised learning methods often fail to generalize.

Influence of Atrioventricular Nodal Reentrant Tachycardia Ablation on Right to Left Inter-atrial Conduction [PDF]

, 2005
Background: Radiofrequency (RF) catheter ablation is the procedure of choice for the potential cure of atrioventricular nodal reentrant tachycardia (AVNRT) with high success rates.

Prolonged PR interval, first-degree heart block and adverse cardiovascular outcomes: a systematic review and meta-analysis [PDF]

, 2016
Objective: First-degree atrioventricular block is frequently encountered in clinical practice and is generally considered a benign process. However, there is emerging evidence that prolonged PR interval may be associated with adverse outcomes. This study

A Rare Case of Nitroglycerin Resistant Coronary Arterial Vasospasm During Coronary Artery Bypass Surgery

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Coronary artery vasospasm following coronary artery bypass grafting (CABG) is a rare but potentially life‐threatening complication that can lead to myocardial ischemia, arrhythmias, and cardiogenic shock. Nitroglycerin‐resistant vasospasm, particularly involving the left main coronary artery (LMCA), poses significant diagnostic and ...

An alternative approach for endocardial pacemaker lead implantation in patient with persistent left superior vena cava [PDF]

Srpski Arhiv za Celokupno Lekarstvo, 2010
Introduction. Persistent left superior vena cava represents a congenital vascular defect of the venous system, which often makes standard 58 cm endocardial lead placement impossible. Case Outline.

Mathematical and Preclinical Investigation of Respiratory Sinus Arrhythmia Effects on Cardiac Output [PDF]

arXiv, 2020
Respiratory sinus arrhythmia (RSA) is heart rate variability in synchrony with respiration although its functional significance not clear. The loss of sinus arrhythmia may indicate underlying heart failure or disease; therefore, there would be a great advantage of knowing how it works and affects the cardio-respiratory system, especially by providing a
