Neural Network Reconstruction of the Left Atrium using Sparse Catheter Paths [PDF]

open access: yesarXiv, 2023
Catheter based radiofrequency ablation for pulmonary vein isolation has become the first line of treatment for atrial fibrillation in recent years. This requires a rather accurate map of the left atrial sub-endocardial surface including the ostia of the pulmonary veins, which requires dense sampling of the surface and takes more than 10 minutes.

A radiographic measurement of left atrial size in dogs [PDF]

open access: yes, 2018
The dimensions of the left atrium in cases with mitral regurgitation are an indirect measurement of its severity. The objective of this study was to evaluate the value of a new radiographic measurement, the radiographic left atrial dimension (RLAD), for ...

A Case of Pulmonary Vein Tumor Presenting as a Left Atrial Mass [PDF]

open access: yes, 2007
Primary cardiac tumors are extremely rare and can originate within the heart or be the result of tumor spread from other sites. We report a female patient with a pulmonary vein tumor extending into the left atrium that had a suspicious primary malignant ...

The clinical anatomy of the left atrial structures used as landmarks in ablation of arrhythmogenic substrates and cardiac invasive procedures [PDF]

open access: yes, 2021
Background: The clinical anatomy of the left atrium is of special interest since many invasive procedures are performed within this chamber. Pulmonary vein isolation, linear transcatheter ablations, transcatheter mitral valve repair procedures and left

The prognostic value of clinical frailty scale and outcomes in older patients undergoing left ventricular assist device implantation

open access: yesAGING MEDICINE, Volume 5, Issue 4, Page 257-263, December 2022., 2022
The main finding in our study is that Clinical Frailty Scale‐defined frailty status was predictive of 1‐year post‐interventional mortality after left ventricular assist device implantation. Abstract Objectives Heart failure impacts patients’ functional capabilities, ultimately leading to frailty.

Whole Heart Anatomical Refinement from CCTA using Extrapolation and Parcellation [PDF]

open access: yesarXiv, 2021
Coronary computed tomography angiography (CCTA) provides detailed an-atomical information on all chambers of the heart. Existing segmentation tools can label the gross anatomy, but addition of application-specific labels can require detailed and often manual refinement.

Giant left atrium [PDF]

open access: yesThorax, 1970
Radiographic evidence of asymmetrical enlargement of the left atrium without atrial infarction is presented. Giant atrial enlargement is rarely symmetrical, the atrial appendage can contribute to the enlargement, and the giant atrium can be effectively trimmed.

Differences in prognosis and underuse of adjuvant chemotherapy between elderly and non‐elderly patients in stage III colorectal cancer

open access: yesAnnals of Gastroenterological Surgery, Volume 7, Issue 1, Page 91-101, January 2023., 2023
This study analyzed data from consecutive patients with stage III colorectal cancer following curative resection and examined the reason for not introducing adjuvant chemotherapy (AC) and the differences in prognosis between completed and incomplete AC in elderly and non‐elderly patients.

Massive Left Atrial Calcification Associated with Mitral Valve Replacement [PDF]

open access: yes, 2010
Calcification of the left atrium can be observed in patients with a long-lasting rheumatic heart disease. However, massive calcification of the atrial wall, so called porcelain or coconut atrium is very rare and has been generally reported only as ...
