Cardiac amyloidosis may occur in any type of systemic amyloidosis. The clinical picture is often characterized by restrictive cardiomyopathy. We report the case of a 41-year-old female patient admitted to the Department of Cardiology with clinical signs of right heart failure: congested jugular veins, hepatomegaly, peripheral edema, ascites associated with atrial fibrillation, low values of arterial blood pressure and oliguria. Echocardiographic findings were helpful for the diagnosis of cardiac amyloidosis: enlarged atrial cavities, normal size ventricles, thickened ventricular septum and posterior left ventricle wall with normal left ventricular ejection fraction, mitral and tricuspid regurgitation...

We report an initial investigation of a subtraction-based method to estimate right ventricle ejection fraction (RVEF) from ECG-gated planar equilibrium radionuclide angiography (ERNA) data. Twenty-six consecutive patients referred for scintigraphic evaluation of cardiac function prior to chemotherapy had ECG-gated first-pass (FP) imaging and ERNA imaging performed following the same radiotracer injection. RVEF was computed from FP images (RVEFFP) and separately from ERNA images (RVEFERNA). Standard methods for computing ejection fractions were used to obtain RVEFFP values...

BACKGROUND: Little is known regarding intergenerational differences in the effects of atrial sepal defect (ASD) closure on the left heart. We therefore analyzed age-related serial changes in the left heart following ASD closure. METHODS: We studied 50 patients with an isolated ASD who underwent successful transcatheter closure using Amplatzer septal occluders (St. Jude Medical, Little Canada, MN, USA) between June 2007 and June 2013. Patients were divided into three age groups: young patients aged ≤17 years; middle-aged patients aged 18-50 years; and older patients aged >50 years...

BACKGROUND/AIMS: The source of thrombi in patients with dilated cardiomyopathy is not necessarily from the dilated left ventricle. Left atrium (LA) and left atrial appendage (LAA) might be in charge for relatively high rate of systemic embolizations in these patients. The main aim of our study was to identify epidemiological predictors in sinus rhythm patients with dilated heart for LA and LAA dilation and/or dysfunction. PATIENTS AND METHODS: This was a prospective cross-sectional study conducted from 2009 to 2014 in 101 sinus rhythm patients with dilated heart...

A man in his late forties had lived as a recluse for more than ten years. He was found dead in his room. At autopsy, subarachnoid hemorrhage (SAH) was detected at the base of the brain, which weighed 1333 g. The cerebellar tonsil was swollen. The cerebral ventricle was enlarged and filled with blood. A hematoma was observed in the upper part of the left side of the cerebellar hemisphere. The location and size of SAH in this case indicated that the rupture of a cerebral aneurysm (CA) had occurred; however, CA was not detected...

BACKGROUND AND OBJECTIVES: Although the regression of pulmonary hypertension (PH) in mitral stenosis (MS) has been studied over varying periods postintervention, corresponding studies on the cardiac chamber alterations after surgery are very limited. We sought to determine the degree of reversal of these and the clinical status in connection with that of pulmonary artery pressures (PAPs) in the early and late postoperative periods. METHODS: The preoperative, early, and 1-year postoperative data - functional class (FC), cardiothoracic ratio (CTR) in chest X-ray (CXR), and echocardiographically left atrium (LA), right atrium (RA), right ventricle (RV), left ventricle (LV), and pulmonary artery (PA) dimensions, PAP, tricuspid regurgitation (TR) - of 50 patients who had mitral valve replacement (MVR) for MS with PH were retrospectively analyzed for correlations with PAP (Pearson's), and their change (t-test), in relation to that in PAP...

Right ventricular failure (RVF) after left ventricular assist device (LVAD) implantation is associated with increased morbidity and mortality, but the identification of LVAD candidates at risk for RVF remains challenging. We undertook a systematic review and meta-analysis of observational studies of risk factors associated with RVF after LVAD implant. Thirty-six studies published between 1 January 1995 and 30 April 2015, comprising 995 RVF patients out of a pooled final population of 4428 patients, were identified...

OBJECTIVE: To assess the incidence, possible risk factors and prognosis of pulmonary arterial hypertension (PAH) in critically ill elderly patients. METHODS: We selected 122 cases admitted to the ICU, ages 60-93 years old. An echocardiography examination was performed within four days after admission to the ICU. PAH is usually suspected if the patient's pulmonary artery systolic pressure ≥ 40 mmHg. We collected echocardiography data, relevant clinical data and routine laboratory data; we then used a statistical method to analyze the risk factors for PAH in critically ill elderly patients and examined its impact on the prognosis...

CASE DESCRIPTION A 2-year-old castrated male mixed-breed dog was evaluated because of a 1-week history of respiratory distress and abdominal distension. Thoracic radiography and echocardiography at that time revealed an enlarged cardiac silhouette and pericardial effusion; abdominal radiography and ultrasonography revealed ascites. CLINICAL FINDINGS At the initial referral examination 5 weeks later, the dog weighed 37.5 kg (82.5 lb) and appeared clinically normal. The only abnormality detected was a grade I/VI systolic murmur on the left side of the thorax...

OBJECTIVES: Functional tricuspid regurgitation (FTR) is common in patients with advanced heart failure and frequently complicates left ventricular assist device implantation yet remains poorly understood. We set out to establish large animal model of FTR that could serve as a research platform to investigate the pathogenesis of FTR associated with end-stage heart failure. METHODS: : Through right thoracotomy, ten adult sheep underwent implantation of pacemaker with epicardial LV lead, five sonomicrometry crystals on the right ventricle, and left and right ventricular telemetry pressure sensors during a beating heart off-pump procedure...

The correlation between hydrocephalus and Chiari type I malformation (CIM) has been debated since Chiari's first descriptions of CIM but some studies have shown that CIM and hydrocephalus (HCP) could cause symptoms/disease of each other or vice versa. Recent research has found that treatment focused on hydrocephalus with ventricle enlargement also provides alleviation of CIM and even of syringomyelia. However, the lack of consensus among previous studies left unanswered the question of how endoscopic third ventriculostomy (ETV) addresses CIM and why it fails...

Posterior reversible encephalopathy syndrome (PRES) is diagnosed based on neuroradiological findings. Typically, PRES is reversible and presents with a good outcome; however, fatal outcomes have been reported. We report an autopsied case showing PRES-like neuroradiological findings associated with premedication including tacrolimus for autologous peripheral blood stem cell transplantation in a 28-year-old woman with a 2-year history of acute myeloid sarcoma/acute myeloid leukemia. Neurological examination revealed disturbed consciousness, muscle weakness in all extremities, and bilaterally diminished tendon reflexes...

BACKGROUND: Right dominant heart (RDH) in fetuses can occur with a number of cardiac as well as noncardiac anomalies. Analysis of the enlargement of the right cardiac chamber in the fetus remains a major challenge for sonographers and echocardiographers. The aim of this study was to report the experience with prenatal diagnosis of RDH in the fetuses over a 7-year period. METHODS: Fetuses with prenatal diagnosis of RDH from July 2009 to July 2016 were evaluated in two different categories: according to the gestational age, Group I (n = 154, second trimester) and Group II (n = 298, third trimester); and according to the fetal echocardiography diagnosis, Group A (n = 452, abnormal cardiac structure) and Group B (n = 90, normal cardiac structure)...

Sleep disruption after myocardial infarction (MI) by affecting ubiquitin-proteasome system (UPS) is thought to contribute to myocardial remodeling and progressive worsening of cardiac function. The aim of current study was to test the hypothesis about the increased risk of developing heart failure due to experience of sleep restriction (SR) after MI. Male Wistar rats (n = 40) were randomly assigned to four experimental groups: (1) Sham, (2) MI, (3) MI and SR (MI + SR) (4) Sham and SR (Sham + SR). MI was induced by permanent ligation of left anterior descending coronary artery...

Enlargement of the left atrium is perceived as a part of athlete's heart syndrome, despite the lack of evidence. So far, left atrial size has not been assessed in the context of exercise capacity. The hypothesis of the present study was that LA enlargement in athletes was physiological and fitness-related condition. In addition, we tried to assess the feasibility and normal values of left atrial strain parameters and their relationship with other signs of athlete's heart. The study group consisted of 114 international-level rowers (17...
