Background: Depending on the degree of infiltration of dry mitral annulus calcification (MAC) into the left ventricular myocardium, calcification removal may cause thinning of the left ventricular wall and increase the risk of post-operative left ventricular rupture. Therefore, the degree of pre-operative infiltration into the left ventricular myocardium should be assessed as accurately as possible. We report a case of caseous calcification of the mitral annulus (CCMA), a subtype of MAC, in an 84-year-old woman; cardiac magnetic resonance imaging (MRI) was useful in assessing the degree of left ventricular infiltration of calcification.
Case Summary: The patient was referred to our hospital for surgery due to respiratory distress and severe mitral insufficiency. Echocardiography revealed a mass under the posterior mitral annulus adjacent to the mitral valve ring, suspected to be a CCMA. Cardiac MRI was performed to assess the risk of left ventricular rupture. Pre-operatively, no valve ring or left ventricular myocardium infiltration was confirmed. Surgical caseous calcification removal and artificial valve implantation within the preserved valve annulus were then performed. The patient had an uneventful post-operative course and was discharged without complications on the 21st post-operative day.
Discussion: In this CCMA case, a pre-operative cardiac MRI was useful for evaluating the degree of the valve annulus and left ventricular myocardial involvement and estimating the risk of left ventricular rupture.

Background: With the growing number of high-risk pregnant women, echocardiography frequently reveals pericardial effusion (PE). However, the clinical implications of PE are unknown.
Method: We analyzed a cohort of 406 high-risk pregnant women who underwent echocardiography in the third trimester between November 2019 and December 2022.

We sought to evaluate the intracardiac morphology and associated cardiovascular anomalies in patients with double inlet right ventricle (DIRV) on multidetector CT angiography. A retrospective search of our departmental database was conducted from January 2014 to January 2023 to identify patients with a diagnosis of DIRV on CT angiography. The intracardiac anatomy and associated cardiovascular abnormalities were systematically evaluated.

Myocyte disarray and fibrosis are underlying pathologies of hypertrophic cardiomyopathy (HCM) caused by genetic mutations. However, the extent of their contributions has not been extensively evaluated. In this study, we investigated the effects of genetic mutations on myofiber function and fibrosis patterns in HCM.

Background: Although anthracycline-related cardiotoxicity is widely studied, only a limited number of echocardiographic studies have assessed cardiac function in breast cancer survivors (BCSs) beyond ten years from anthracycline treatment, and the knowledge of long-term cardiorespiratory fitness (CRF) in this population is scarce. This study aimed to compare CRF assessed as peak oxygen uptake (V̇O), cardiac morphology and function, and cardiovascular (CV) risk factors between long-term BCSs treated with anthracyclines and controls with no history of cancer.
Methods: The CAUSE (Cardiovascular Survivors Exercise) trial included 140 BCSs recruited through the Cancer Registry of Norway, who were diagnosed with breast cancer stage II to III between 2008 and 2012 and had received treatment with epirubicin, and 69 similarly aged activity level-matched controls.

Purpose: We sought to investigate the expression of MALAT1, plasma brain natriuretic peptide, and Tei index in sepsis-induced myocardial injury.
Methods: The current retrospective analysis focused on 146 sepsis patients admitted to our hospital from February 2021 to March 2023. Based on the presence or absence of myocardial injury, the patients were divided into two groups: the sepsis group (n = 80) and the sepsis-induced myocardial injury group (n = 66).
