Aging is usually accompanied with overt structural and functional changes as well as suppressed autophagy in the heart although the precise regulatory mechanisms are somewhat unknown. Here we evaluated the role of the innate proinflammatory mediator toll-like receptor 4 (TLR4) in cardiac aging and the underlying mechanism with a focus on autophagy. Cardiac geometry and function were monitored in young or old wild-type (WT) and TLR4 knockout (TLR4-/- ) mice using echocardiography, IonOptix® edge-detection and fura-2 techniques...

Asymmetrical septal occluder device (ASOD) has made percutaneous closure of ventricular septal defect an easy and effective management option. Although there are reports of aortic and tricuspid valvular regurgitation after deployment of ASOD, only few cases of tricuspid stenosis (TS) has been reported so far in the literature. We report a case of malaligned ASOD that occurred after successful device closure resulting in TS along with mild tricuspid and aortic regurgitation requiring surgical retrieval. Transesophageal echocardiography played crucial role in detecting the cause of tricuspid valve dysfunction besides providing continuous monitoring during the procedure...

Volume overload is an important, may be the foremost, independent prognostic factor determining the outcome of hemodialysis patients. Therefore, it is crucial to measure fluid status of these patients and avoid volume overload. This review aims to evaluate volume overload, its effects on patients with renal diseases and current methodologies measuring volume status in the body. These techniques will be first classified as clinical evaluation and non-clinical and/or instrumental techniques, which includes biomarkers, ultrasonography, relative blood volume monitoring, bioimpedance, echocardiography, pulmonary artery catheterization, esophageal and/or suprasternal Doppler, and blood viscosity...

BACKGROUND: The biplane Simpson's method is considered the gold standard to assess and monitor left ventricular (LV) ejection fraction (EF) in critically ill patients. Recently, a new semiautomatic technique based on speckle tracking echocardiography called "Auto-EF" has been introduced. We compared LVEF values obtained with biplane Simpson's method and Auto-EF by two groups of operators: trainee echocardiography intensivists and experienced echocardiographers. METHODS: A standard transthoracic echocardiography was performed on 37 patients...

Mitral valve prolapse (MVP) is a common and benign condition. However, some anatomic forms have been recently associated with life-threatening ventricular arrhythmias and sudden cardiac death. Imaging MVP holds the promise of individualized MVP risk assessment. Noninvasive imaging techniques available today are playing an increasingly important role in the diagnosis, prognosis and monitoring of MVP. In this article, we will review the current evidence on arrhythmogenic MVP, with special focus on the utility of echocardiography and CMR for identifying benign and "malignant" forms of MVP...

BACKGROUND: Fukutin-related protein (FKRP) mutations are the most common cause of dystroglycanopathies known to cause both limb girdle and congenital muscular dystrophy. The P448Lneo- mouse model has a knock-in mutation in the FKRP gene and develops skeletal, respiratory, and cardiac muscle disease. METHODS: We studied the natural history of the P448Lneo- mouse model over 9 months and the effects of twice weekly treadmill running. Forelimb and hindlimb grip strength (Columbus Instruments) and overall activity (Omnitech Electronics) assessed skeletal muscle function...

BACKGROUND: Patients undergoing cardiac surgery need extensive and invasive monitoring, which needs to be individually adapted for each patient and requires a diligent risk-benefit analysis. The use of a pulmonary artery catheter (PAC) seems to be justifiable in certain cases; therefore, the preoperative diagnosis of pulmonary hypertension represents an indication for perioperative monitoring with PAC in the S3 guidelines of the German Society for Anesthesiology and Intensive Care Medicine (DGAI)...

PURPOSE OF REVIEW: To review the different methods available for the assessment of cardiac output (CO) and describe their specific indications in intensive care and perioperative medicine. RECENT FINDINGS: In critically ill patients, persistent circulatory shock after initial resuscitation is an indication for the assessment of CO to monitor the response to fluids and vasoactive agents. In patients with circulatory shock associated with right ventricular dysfunction, pulmonary artery hypertension, or acute respiratory distress syndrome, invasive CO monitoring using indicator dilution methods is indicated...

Hypothalamic obesity is often complicated in patients with craniopharyngioma due to hypothalamic damage by the tumor itself, treatment modalities, and associated multiple pituitary hormone deficiency. Hypothalamic obesity causes secondary diseases such as nonalcoholic fatty liver disease (NAFLD) and diabetes mellitus (DM). We report a 19-year-old female who was diagnosed with craniopharyngioma, developed hypothalamic obesity after tumor resection, and progressed to hepatopulmonary syndrome. She manifested NAFLD 1 year after tumor resection...

PURPOSE OF REVIEW: The present review discusses the current role of the pulmonary artery catheter (PAC) in the hemodynamic monitoring of critically ill patients. RECENT FINDINGS: The PAC has an important role in the characterization and management of hemodynamic alterations in critically ill patients. Use of the PAC has decreased in the last 30 years because of recent advances in less invasive hemodynamic monitoring techniques, in particular transpulmonary thermodilution and echocardiography, combined with the publication of the results of several randomized trials that failed to show improvements in outcome with the use of the PAC in various settings...

BACKGROUND AND OBJECTIVE: Atrial fibrillation is the most common cardiac arrhythmia, which may occur during the perioperative period and lead to hemodynamic instability due to loss of atrial systolic function. During atrial fibrillation management, electrical cardioversion is one of the therapeutic options in the presence of hemodynamic instability; however, it exposes the patient to thromboembolic event risks. Transesophageal echocardiography is a diagnostic tool for thrombi in the left atrium and left atrial appendage with high sensitivity and specificity, allowing early and safe cardioversion...
