We present the case of a 33-year-old man referred to our institution with a diagnosis of severe mitral valvular stenosis and insufficiency. We realized the valvular disease was due to an "anomalous mitral arcade," a rare congenital malformation of the mitral tensor apparatus characterized by enlarged papillary muscles connected to mitral leaflets by a typical fibrous tissue bridge. This arrangement creates a fibrous continuity between valvular and subvalvular apparatus. The reported echocardiographic images shows in detail the anatomic and functional features of this rare condition.

Predicting Mortality and Hospitalization in Heart Failure With Preserved Ejection Fraction by Using Machine Learning.
JACC Asia
December 2024
Division of Cardiology, Department of Internal Medicine, Chang Gung Memorial Hospital at Linkou, and Chang Gung University College of Medicine, Taoyuan, Taiwan.
Background: Few studies have incorporated echocardiography and laboratory data to predict clinical outcomes in heart failure with preserved ejection fraction (HFpEF).
Objectives: This study aimed to use machine learning to find predictors of heart failure (HF) hospitalization and cardiovascular (CV) death in HFpEF.
Methods: From the Chang Gung Research Database in Taiwan, 6,092 HFpEF patients (2,898 derivation, 3,194 validation) identified between 2008 and 2017 were followed until 2019.
The effect of moderate intensity aerobic exercise on cardiovascular function, cardiorespiratory fitness and estrogen receptor alpha gene in overweight/obese postmenopausal women: A randomized controlled trial.
J Mol Cell Cardiol Plus
December 2022
Drug Applied Research Center, Tabriz University of Medical Sciences, Tabriz, Iran.
Objective: The purpose of this study was to examine the effect of 12 weeks of moderate intensity aerobic exercise on echocardiographic and cardiorespiratory fitness (CRF) parameters, lymphocyte estrogen receptor alpha (ERα) gene expression and sex hormones (17β-estradiol and progesterone) in overweight/obese postmenopausal women (OPMW).
Methods: Twenty-seven sedentary OPMW aged 45 to 65 years old were randomly assigned to exercise (EX, n = 14) and control (C, n = 13) groups. The EX group performed warm up-walking/jogging moderate intensity aerobic exercise program- recovery (60 min/day, 3 days/week at 70 % of maximal heart rate reserve for 12 weeks) while the C group participated in no intervention and maintained their daily physical activity level, sedentary normal lifestyle and dietary habits during 12-week.

Background: Constrictive pericarditis (CP) can arise from various causes, including post-operative degeneration, tuberculosis, and sequelae of pericarditis. Immunoglobulin (Ig) G4-related disease is a rare but recognized cause of CP. However, the specific mechanisms underlying these aetiologies and pathologies remain unclear.

Post-capillary hypertension resulting from mitral regurgitation is typically considered a contraindication for single lung transplantation due to heightened risks of primary graft dysfunction. This case report highlights a 66-year-old COPD patient with severe mitral regurgitation who was deemed ineligible for surgical mitral replacement. As an alternative, transcatheter mitral valve replacement was successfully performed, resulting in the normalization of pulmonary artery pressures.
