We experienced 2 emergency surgical cases of severe mitral valve regurgitation due to papillary muscle rupture. Case 1:a 69-year-old man presented with respiratory and cardiac failure due to mitral regurgitation. He had no history of myocardial infarction. Mitral valve repair with artificial cords was performed. The papillary muscle of the anterior leaflet was ruptured. The postoperative course was uneventful. Case 2:a 80-year-old man came to our hospital with cardiac arrest. Emergency coronary intervention was performed to the right coronary and intraaortic balloon pumping was inserted...

BACKGROUND: Fluid management remains a major challenge of hemodialysis (HD) care, with serious implications for morbidity and mortality. Intradialytic fluid management is typically guided by blood pressure, an indirect resultant of hemodynamics status. Direct measurements of hemodynamic parameters may improve cardiovascular outcomes by providing rational bases for intervention. We compare stroke volume (SV) measurements using a noninvasive, regional biompedance cardiography device (NiCaS) with Doppler echocardiography (Echo) in HD setting...

The aim of the research is to study the peculiarities of cardiac morphometric parameters, the parameters of central hemodynamics and their impact on the course of hemodynamic ischemic stroke in acute period. 116 patients were performed Echo-Doppler-cardiography in acute period of hemodynamic ischemic stroke in order to evaluate cardiac morphometric parameters. These patients were also performed transcranial duplex scanning. The results established that among significant clinical factors that influence the course of the acute period of hemodynamic ischemic stroke the most important are: the size of the focus, the level of consciousness on the 1st day, primary systolic arterial pressure, age of the patient...

Various non-invasive methods are available to measure cardiac output (CO) during pregnancy. We compared serial measures of CO using various methods to determine which provided the least variability. Ten patients with spontaneous pregnancy had estimation of CO at baseline prior to becoming pregnant and at the end of the first and third trimesters. Echocardiographic data were used to estimate CO using the Teichholz method, Simpson's biplane method, and the Doppler determined velocity time integral (VTI) method...

INTRODUCTION: Enhanced External Counter Pulsation (EECP) is a non-invasive treatment option for patients with Coronary Artery Disease (CAD). The treatment has shown to augment diastolic pressure and reduce Left Ventricular (LV) after-load by reducing systemic vascular resistance. The effect of EECP in standard brachial blood pressure and central haemodynamic parameters are not known. AIM: We hypothesized that EECP may have differential effect in CAD patients with low systolic blood pressure when compared to normal systolic pressure and the mechanism underlying this differential effect may be due to improvement in LV function...

Drug-induced cardiomyopathy can be life-threatening in patients with cancer. Our objective was to explore early detection of drug-induced cardiomyopathy in children with cancer. We enrolled pediatric outpatients diagnosed with cancer between 2012 and 2013. In addition, we recruited pediatric outpatients in good general condition without cardiac disease or cancer, as controls. We measured the serum levels of biomarkers and performed chest radiography, electrocardiography, and ultrasound cardiography (UCG). We analyzed left ventricular (LV) torsion and torsion-related parameters using 2-dimensional (2D) speckle tracking on UCG...

AIMS: Previous studies have shown that aortic valve calcification (AVC) was associated with cardiovascular events and mortality. On the other hand, periprocedural myocardial injury (PMI) in percutaneous coronary intervention (PCI) is a well-known predictor of subsequent mortality and poor clinical outcomes. The purpose of the study was to assess the hypothesis that the presence of AVC could predict PMI in PCI. METHODS: This study included 370 patients treated with PCI for stable angina pectoris...

The novel Middle east respiratory syndrome coronavirus (MeRS-CoV) has been identified as a cause of pneumonia; however, it has not been reported as a cause of acute myocarditis. A 60-year-old man presented with pneumonia and congestive heart failure. On the first day of admission, he was found to have an elevated troponin-l level and severe global left ventricular systolic dysfunction on echo-cardiography. The serum creatinine level was found mildly elevated. Chest radiography revealed in the lower lung fields accentuated bronchovascular lung markings and multiple small patchy opacities...

The identification of predictors for the progression of chronic Chagas cardiomyopathy (CCC) is essential to ensure adequate patient management. This study looked into a non-concurrent cohort of 165 CCC patients between 1985 and 2010 for independent predictors for CCC progression. The outcomes were worsening of the CCC scores and the onset of left ventricular dysfunction assessed by means of echo-Doppler cardiography. Patients were analyzed for social, demographic, epidemiologic, clinical and workup-related variables...

A 53-year-old male was admitted due to an asymptomatic third degree atrioventricular (AV) block of proximal type (QRS duration below 0,12 sec.). With telemetry a normal heart rate was observed and a stress test showed a maximum heart rate of 101% of the expected. Blood samples and stress echo-cardiography showed normal values. Permanent pacemaker (PM) placement was rejected and the patient was followed in the outpatient clinic. PM implantation carries a risk of complications but without it the condition can progress...

While simultaneous acquisition of electrocardiography (ECG) data during MRI is a widely used clinical technique, the effects of the MRI environment on impedance cardiography (ICG) data have not been characterized. We collected echo planar MRI scans while simultaneously recording ECG and thoracic impedance using carbon fiber electrodes and customized amplifiers. Here, we show that the key changes in impedance (dZ/dt) and features of the ECG waveforms are not obstructed during MRI. We present a method for ensemble averaging ICG/ECG signals collected during MRI and show that it performs comparably with signals collected outside the MRI environment...

BACKGROUND: Cross-sectional studies suggest that left ventricular (LV) and arterial elastance (stiffness) increase with age, but data examining longitudinal changes within human subjects are lacking. In addition, it remains unknown whether age-related LV stiffening is merely a reaction to arterial stiffening or caused by other processes. METHODS AND RESULTS: Comprehensive echo-Doppler cardiography was performed in 1402 subjects participating in a randomly selected community-based study at 2 examinations separated by 4 years...
