Retinal Vessel Segmentation: A Comprehensive Review From Classical Methods to Deep Learning Advances (1982–2025)

Advanced Intelligent Systems, EarlyView.
Four decades of retinal vessel segmentation research (1982–2025) are synthesized, spanning classical image processing, machine learning, and deep learning paradigms. A meta‐analysis of 428 studies establishes a unified taxonomy and highlights performance trends, generalization capabilities, and clinical relevance.

"Vanishing" pulmonary valve stenosis

Annals of Pediatric Cardiology, 2012
Both spontaneous resolution and progression of mild pulmonary valve stenosis (PS) have been reported. We reviewed characteristics of the pulmonary valve (PV) to determine factors that could influence resolution of mild PS.Fifteen asymptomatic pediatric patients with spontaneous resolution of isolated mild PS were retrospectively reviewed.There was no ...

Pulmonary valvulotomy in a fetus with pulmonary atresia with intact ventricular septum : first experience in Turkey [PDF]

, 2012
The mortality and morbidity of children with pulmonary atresia with intact ventricular septum (PA/IVS) is closely related with right ventricle hypoplasia and its consequent hemodynamics.

Complex Genetic Architecture in RASopathies: Constitutional PTPN11 and Mosaic RIT1 Pathogenic Variants Underlying Severe Noonan Syndrome With Adult‐Onset Acute Myeloid Leukemia

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Noonan syndrome (NS) is a genetically heterogeneous disorder characterized by a broad spectrum of clinical features resulting from dysregulation of the RAS/MAPK pathway. Although complex genotypes are increasingly recognized in NS, cases harboring two distinct pathogenic variants in different NS genes remain extremely rare.

A case of left atrial myxoma accompanied by pancytopenia and pathological findings suggestive of pulmonary hypertension

, 1974
A case of left atrial myxoma accompanied by peculiar symptoms is reported. A 15-year old boy had progressive congestive heart failure and three episodes of acute attacks of panctyopenia. The anemia was accompanied by helmet-shaped, broken red blood cells,

Lymphatic Abnormalities in Noonan Syndrome Extend Beyond Clinically Apparent Disease

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Lymphatic disease represents a well‐described manifestation of Noonan syndrome (NS), yet the full phenotypic spectrum remains incompletely characterized, especially in asymptomatic individuals. We conducted a cross‐sectional study including 10 individuals with NS (four with peripheral lymphedema and six without) and 10 age‐ and sex‐matched ...

Echocardiography to Evaluate Pulmonary Stenosis

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2020
Congenital pulmonary stenosis (PS) is a common term for lesions causing right ventricular outflow obstruction. It can be further classified as the valvar, supravalvar, and infundibular PS. The PS may often present with other congenital heart diseases. In

Coronary to pulmonary artery fistula associated with significant coronary atherosclerosis and severe aortic valve stenosis: A Case Report

Radiology Case Reports, 2022
Coronary artery fistulas are anomalous connections between one or two coronary arteries with either a cardiac chamber or any major blood vessels (coronary sinus, superior vena cava, pulmonary veins and pulmonary artery).

Outcomes in Establishing Individual Vessel Patency for Pediatric Pulmonary Vein Stenosis

, 2021
The purpose of this study was to determine what patient and pulmonary vein characteristics at the diagnosis of intraluminal pulmonary vein stenosis (PVS) are predictive of individual vein outcomes.

Descriptive Epidemiology From the Myhre Syndrome Foundation Registry: The Value of Self‐Reported Data

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Myhre syndrome is an ultrarare genetic disease characterized by short stature, distinct craniofacial features, cardiovascular and respiratory fibrosis and stenosis, neurodevelopmental delays, autism, intellectual disability, and hearing loss. The natural history of Myhre syndrome is still not fully understood due to a small patient population ...
