Cardiovascular function and ballistocardiogram: a relationship interpreted via mathematical modeling [PDF]
, 2019 Objective: to develop quantitative methods for the clinical interpretation of the ballistocardiogram (BCG). Methods: a closed-loop mathematical model of the cardiovascular system is proposed to theoretically simulate the mechanisms generating the BCG ...

Geometric analysis on the unidirectionality of the pulmonary veins for atrial reentry [PDF]
arXiv, 2013 It is widely believed that the pulmonary veins (PVs) of the atrium play the central role in the generation of atrial reentry leading to atrial fibrillation, but its mechanism has not been analytically explained. In order to improve the current clinical procedures for atrial reentry by understanding its mechanism, geometrical analysis is proposed on the

3 year old with chronic wet cough : Intralobar Bronchopulmonary sequestration [PDF]
, 2016 Bronchopulmonary sequestration (BPS) is a rare congenital foregut anomaly of the lung, consisting of nonfunctioning primitive tissue that does not communicate with the healthy tracheobronchial tree.

Use of IT tools to search for a correlation between weather factors and onset of pulmonary thromboembolism [PDF]
arXiv, 2020 Pulmonary embolism (PE) and deep vein thrombosis (DVT) are gathered in venous thromboembolism (VTE) and represent the third cause of cardiovascular diseases. Recent studies suggest that meteorological parameters as atmospheric pressure, temperature, and humidity could affect PE incidence but, nowadays, the relationship between these two phenomena is ...

Role of MDCT in evaluation of congenital and acquired anomalies of pulmonary venous drainage
The Egyptian Journal of Radiology and Nuclear Medicine, 2018 Objective: This work aimed for detection of different congenital and acquired abnormalities affecting the pulmonary veins using multislice computed tomography (MSCT). Patients and methods: This study was carried on 74 patients.

Automated segmentation of the pulmonary arteries in low-dose CT by vessel tracking [PDF]
arXiv, 2011 We present a fully automated method for top-down segmentation of the pulmonary arterial tree in low-dose thoracic CT images. The main basal pulmonary arteries are identified near the lung hilum by searching for candidate vessels adjacent to known airways, identified by our previously reported airway segmentation method.

Unusual echocardiographic finding leading to diagnosis of pulmonary sequestration [PDF]
, 2008 Pulmonary sequestration is an embryonic mass of non- functioning lung tissue that does not communicate with the tracheobronchial tree and has a reported incidence of 0.15%-6.4% of all the pulmonary malformations.
