Summary: Mitral valve prolapse (MVP) is a common valvular disorder that can lead to severe cardiac issues. Left ventricular (LV) remodeling is an important manifestation of MVP, but its mechanism remains unclear. Volume overload and cardiomyopathy may be two key factors in LV remodeling.

Summary: Undersizing the mitral annulus with an annuloplasty ring can restore valvular competence, but unphysiologically impair ventricle mechanics. Mitral valve repair strategies should focus not only on restoring valve competence, but preserving ventricle mechanics.

Summary: Secondary mitral regurgitation occurs when a left ventricular problem causes leaking of the mitral valve. This study reveals the mechanical properties of affected tissues through biomechanical analysis. Samples from secondary mitral regurgitation show thickness increase and changes in anisotropy index. Additionally, chord samples in secondary mitral regurgitation are slightly thicker and less stiff at high stress.

Summary: Rates of stress cardiomyopathy have increased during the coronavirus pandemic. This article presents a case of shock caused by Takotsubo cardiomyopathy secondary to left ventricular outflow tract obstruction, mitral regurgitation, and left ventricular dysfunction. The contrasting management strategy of these opposing forces poses a clinical challenge.

Summary: This study evaluated the impact of age and sex on left ventricular remodeling and outcomes in patients with aortic regurgitation (AR). It found that older patients and women with chronic AR maintained smaller left ventricular volumes than younger patients and men, respectively, and experienced adverse events at lower volumes.

Summary: This study aimed to evaluate the additive value of myocardial work indices in predicting clinical events in patients with primary mitral regurgitation (PMR). The study found that changes in myocardial work indices were related to patient prognosis and could help in better selecting candidates for early surgery.

Summary: Insufficient rotational movement of the left ventricle is significantly associated with functional regurgitation of the mitral valve, suggesting a potential novel mechanism and therapeutic target. In patients with functional mitral regurgitation, reduced peak systolic twist of the left ventricle negatively correlates with regurgitant volume, indicating the importance of rotational LV motion in this condition.

Summary: This study investigated the short- and long-term changes in left ventricular ejection fraction (LVEF) after mitral valve repair in patients with chronic primary mitral regurgitation. The results showed that preoperative LVEF and left ventricular end-systolic diameter values can influence the patterns of short- and long-term changes in postoperative LVEF.

Summary: This study investigated the effects of pulmonary stenosis and pulmonary insufficiency on ventricular interactions using a porcine model. The results showed that pulmonary stenosis was associated with preserved LV systolic function and evidence of some LV diastolic dysfunction, while pulmonary insufficiency was associated with LV systolic dysfunction and noncompliance.

Summary: Persistent moderate-to-severe MR is present in one fourth of patients after cfLVAD implantation, and is associated with increased incidence of right heart failure, higher mean pulmonary pressure, and pulmonary capillary wedge pressure with no effect on 1 year survival. Increased left atrium size was a significant predictor of persistent moderate-to-severe MR at 6 months.

Summary: This study aimed to assess the incidence and predictors of mitral regurgitation (MR) progression in patients with rheumatic heart disease (RHD). The results showed that age and left atrial volume were predictors of MR progression in RHD patients. The study also suggested that left atrial enlargement may play a role in the link between primary MR and secondary MR in RHD patients.

Summary: This study assessed the diagnostic performance of elastography point quantification (ElastPQ), transient elastography (TE), and aspartate aminotransferase-to-platelet count ratio index (APRI) for the staging of liver fibrosis in patients with chronic viral hepatitis. It found that ElastPQ showed similar diagnostic accuracy to TE and was more accurate than APRI.

Summary: The study aimed to investigate the association between low-normal left ventricular ejection fraction (LVEF) and adverse outcomes in hypertrophic cardiomyopathy (HCM), as well as evaluate the predictive power of LVEF in the conventional HCM sudden cardiac death (SCD)-risk model. The results showed that low-normal LVEF was an independent predictor of heart failure hospitalization and cardiovascular death in patients with HCM.

Summary: This study found that 2D global longitudinal strain (GLS) is associated with cardiovascular outcomes in patients with left bundle-branch block, but the predictive value of 3D speckle-tracking echocardiography has not been investigated in these patients. The study retrospectively analyzed the association between 2D and 3D strains and left ventricular ejection fraction (LVEF) in patients with preserved or reduced LVEF. The results showed that 2D-GLS is predictive of maintaining LVEF in patients with preserved LVEF, while a lower 3D-global circumferential strain is associated with persistently reduced LVEF in patients with reduced LVEF.

Summary: This study investigated the association between the use of ACEi, ARB, or non-RASi and incident cardiovascular events in a nationwide hypertension cohort. The results showed that patients on ACEi and ARB had lower risks of myocardial infarction, ischemic stroke, atrial fibrillation, heart failure, and all-cause deaths compared to those on non-RASi. Sensitivity analysis and propensity score matching results supported these findings.

Summary: The aim of this study was to investigate the prognostic utility of left ventricular global longitudinal strain (LV-GLS) in patients with hypertrophic cardiomyopathy (HCM) and a left ventricular ejection fraction (LVEF) of 50-60%. The study included 349 HCM patients with an LVEF of 50-60%, and the results showed that LV-GLS was an independent predictor of a composite outcome including cardiovascular death in these patients. Therefore, LV-GLS can aid in risk stratification in HCM patients with an LVEF of 50-60%.

Summary: With the development of immunosuppressive drugs, xenotransplantation has made major advances by understanding the immune rejection mechanisms. Hyperacute rejection is provoked by three main carbohydrate antigens on porcine endothelial cells: α1,3-galactose, SDa blood group antigen, and N-glycolylneuraminic acid. Genetic engineering has enabled knock-outs of these antigens, reducing rejection rates. Co-stimulation blockade and expression of multiple human transgenes in xenografts have also improved survival. However, there are still obstacles including zoonotic infections, physiological discordances, and healthcare costs.

Summary: Hypertrophic cardiomyopathy (HCM) is a common inheritable cardiomyopathy with a high disease burden in Korea. Sudden cardiac death, atrial fibrillation and thromboembolic risk, dynamic left ventricular outflow tract obstruction, and heart failure progression are important issues in HCM. Implantable cardioverter-defibrillators and anticoagulation are effective strategies for preventing sudden cardiac death and reducing thrombotic risk. Symptomatic dynamic LVOT obstruction can be improved with negative inotropes and septal reduction therapy. Myocardial fibrosis plays a role in the progression of heart failure in HCM patients.
