Non-pharmaceutical Interventions for Hypertrophic Cardiomyopathy: A Mini Review
Frontiers in Cardiovascular Medicine, 2021 Hypertrophic cardiomyopathy is an inherited cardiovascular disease, and 70% of patients have left ventricular outflow tract obstruction. Ventricular septal myectomy has been the gold standard treatment for most patients with refractory symptoms.

Differences in coronary flow and myocardial metabolism at rest and during pacing between patients with obstructive and patients with nonobstructive hypertrophic cardiomyopathy [PDF]
, 1987 Fifty patients with hypertrophic cardiomyopathy underwent invasive study of coronary and myocardial hemodynamics in the basal state and during the stress of pacing.

Right Ventricular Myxoma Obstructing the Right Ventricular Outflow Tract [PDF]
Circulation, 2000 A12-year-old previously healthy girl developed syncope when walking at school. When she was seen in the emergency department, her heart rate was 115 bpm, the precordial impulse was active, and a thrill was palpated. Third and fourth heart sounds were heard. A grade 4/6 systolic ejection murmur was heard at the …

Machine Learning-based Efficient Ventricular Tachycardia Detection Model of ECG Signal [PDF]
arXiv, 2021 In primary diagnosis and analysis of heart defects, an ECG signal plays a significant role. This paper presents a model for the prediction of ventricular tachycardia arrhythmia using noise filtering, a unique set of ECG features, and a machine learning-based classifier model.

Pathology of Left Ventricular Outflow Tract Obstruction [PDF]
Circulation, 1965 Lesions causing obstruction to the outflow of blood from the left ventricle may reside in the ascending aorta, the aortic valve, or the outflow tract of the left ventricle. Conditions involving the ascending aorta are usually congenital, and designated as supravalvular aortic stenosis. A tendency is present for this condition to be associated

Medicina, 2023 Combined cases of hypertrophic obstructive cardiomyopathy (HOCM) and pulmonary arterial hypertension (PAH) are rare and have a management dilemma. Although preload is crucial in the management of HOCM, anti-PAH agents dramatically change the preload ...

Semantic-aware Temporal Channel-wise Attention for Cardiac Function Assessment [PDF]
arXiv, 2023 Cardiac function assessment aims at predicting left ventricular ejection fraction (LVEF) given an echocardiogram video, which requests models to focus on the changes in the left ventricle during the cardiac cycle. How to assess cardiac function accurately and automatically from an echocardiogram video is a valuable topic in intelligent assisted ...
