Identifying the Severity of Heart Valve Stenosis and Regurgitation Among a Diverse Population Within an Integrated Health Care System: Natural Language Processing Approach

If a negation was found (eg, no aortic stenosis, without evidence of aortic stenosis), the identified stenosis or regurgitation term was ignored. Search for history terms (eg, a prior study showed trace mitral regurgitation) associated with the identified stenosis and regurgitation terms. If an associated history term was detected, the detected stenosis and regurgitation term was also ignored (Table S6 in Multimedia Appendix 1). Search for severity terms.

Cardiac Health Assessment Using a Wearable Device Before and After Transcatheter Aortic Valve Implantation: Prospective Study

As transcatheter aortic valve implantation (TAVI) for severe aortic stenosis is increasingly used for older adults, including a high percentage of patients with substantial comorbidity, improvement in quality of life (Qo L) is as important as extending life expectancy [1,2]. Not all TAVI patients benefit from improved physical activity, as assessed by a 6-minute walking test (6 MWT) or the Qo L questionnaire [3,4], nor does physical activity change the incidence of aortic stenosis [5].

Rapidly Deteriorating Degenerative Cervical Myelopathy Following Ventricular Shunt Revision for Hydrocephalus: Case Report

Degenerative cervical myelopathy (DCM) is the umbrella term for a range of chronic spinal injuries caused by cervical stenosis due to degenerative or congenital pathology [1,2]. DCM presents with motor or sensory dysfunction in the upper or lower limbs, such as the loss of dexterity, paresthesia and imbalance, pain, and bladder and bowel dysfunction [3]. We report the case of a patient with worsening DCM following the treatment of coexisting hydrocephalus.

Accuracy of Artificial Intelligence–Based Automated Quantitative Coronary Angiography Compared to Intravascular Ultrasound: Retrospective Cohort Study

Coronary angiography is a key step in defining the coronary anatomy and severity of coronary arterial stenosis [1]. Percent diameter stenosis (%DS) based on a 2 D image is usually used as evidence of ischemia or guidance for further physiology study [2]. Despite advances in intravascular imaging and physiology, coronary intervention is mostly performed based on coronary angiography alone [3]. Efforts have been made to analyze coronary angiography images quantitatively and objectively [4].

Tackling Research Inefficiency in Degenerative Cervical Myelopathy: Illustrative Review

Ultimately, this results in stenosis of the spinal canal leading to cord compression, mechanical stretch, repetitive microtrauma, and chronic reduction in cord blood flow [1,2]. A complex pathological cascade follows with neuroinflammation, demyelination, neurodegeneration, and gliosis, resulting in the clinical entity we know as myelopathy [1,3,4]. The prevalence of DCM has proven difficult to ascertain owing to the novel umbrella term, difficulty in diagnosis, and the relative paucity of data [1].
