Introduction: Myxomas are the most common benign tumors of the heart. They vary widely in size, and little is known about their growth rate. The present case report is, we believe the first in bibliography that provides images of an apical left ventricular myxoma from transthoracic echocardiography and computed tomography scans taken a year apart.
Case Presentation: We present the rare case of a 65-year-old asymptomatic Caucasian man with an apical left ventricular myxoma that grew over a 12-month period. Our patient underwent successful surgical excision of the tumor and had an uneventful postsurgical recovery period.
Conclusions: Left ventricular myxomas are benign and curable tumors. They do not usually present with systemic symptomatology and most of them are diagnosed as sequelae of syncope caused by left ventricular outflow tract obstruction or systemic embolization. Because they are usually removed after diagnosis, the growth rate of myxomas is generally unknown. We present a rare case of the asymptomatic presentation of a left ventricular myxoma and its documented growth during a 12-month period.

To investigate the correlation between fetoplacental circulation and maternal left ventricular myocardial work (MW) parameters in patients with preeclampsia (PE) and the prediction of fetal hypoxia. Seventy-eight PE patients (PE group) were assigned to intrauterine-hypoxia (27) and non-intrauterine-hypoxia (51) groups, and 45 healthy pregnant women were controls. The receiver operating characteristic (ROC) curve evaluated the diagnostic efficacy of each parameter for fetal intrauterine hypoxia.

Despite the critical importance of cardiac rehabilitation (CR) in CHF management, while studies have explored the effectiveness of various CR delivery modes and offered valuable context-specific insights, their relative efficacy remains inconsistent across different patient groups, healthcare environments, and intervention approaches. A clearer understanding requires comprehensive comparisons and in-depth analyses to address these variations.

Cardiac sex-difference functional studies have centred on measurements of twitch force and Ca dynamics. The energy expenditures from these two cellular processes: activation (Ca handling) and contraction (cross-bridge cycling), have not been assessed, and compared, between sexes. Whole-heart studies measuring oxygen consumption do not directly measure the energy expenditure of these activation-contraction processes.

Background: Long-term consumption of Western Diet (WD) is a well-established risk factor for the development of cardiovascular disease (CVD); however, there is a paucity of studies on the long-term effects of WD on the pathophysiology of CVD and sex-specific responses.
Methods: Our study aimed to investigate the sex-specific pathophysiological changes in left ventricular (LV) function using transthoracic echocardiography (ECHO) and LV tissue transcriptomics in WD-fed C57BL/6 J mice for 125 days, starting at the age of 300 through 425 days.
Results: In female mice, consumption of the WD diet showed long-term effects on LV structure and possible development of HFpEF-like phenotype with compensatory cardiac structural changes later in life.

Previous studies demonstrated that dexmedetomidine (Dex) posttreatment aggravated myocardial dysfunction and reduced survival in septic mice. Yet, whether Dex elicits similar effects in septic patients as defined by Sepsis-3 remains unknown. This study sought to assess the effects of Dex-based sedation on mortality and cardiac dysfunction in septic patients defined by Sepsis-3 and to further reveal the mechanisms in septic rats.
