BACKGROUND: Cardiac lipomas are rare benign tumors of the heart. They are usually asymptomatic and are thus most often diagnosed on autopsies. Symptoms, when present, depend upon the location within the heart. Typical locations are the endocardium of the right atrium and the left ventricle. Diagnostic modality of choice is cardiac MRI. Treatment guidelines have not yet been established due to the very low prevalence of these tumors and are thus guided by the patient's symptomatology. CASE PRESENTATION: We describe a case of an invasive cardiac lipoma, wherein the initial symptom of the patient was shortness of breath...

INTRODUCTION: Myocardial perfusion imaging (MPI) is widely used in the evaluation of known and suspected coronary artery disease (CAD). Imaging of heart in stress and rest enables the comparison of myocardial uptake of radiotracer in proportion to the needs and coronary flow, which is used for detection of perfusion defects. Exercise stress and pharmacologic agents are used for the stressing purpose. Novel pharmacologic stressor regadenoson is A2A selective adenosine agonist, which selectively binds to the adenosine receptors in coronary arteries causing coronary dilatation...

BACKGROUND: Segmented cine imaging with a steady-state free-precession sequence (Cine-SSFP) is currently the gold standard technique for measuring ventricular volumes and mass, but due to multi breath-hold (BH) requirements, it is prone to misalignment of consecutive slices, time consuming and dependent on respiratory capacity. Real-time cine avoids those limitations, but poor spatial and temporal resolution of conventional sequences has prevented its routine application. We sought to examine the accuracy and feasibility of a newly developed real-time sequence with aggressive under-sampling of k-space using sparse sampling and iterative reconstruction (Cine-RT)...

BACKGROUND: The clinical features of bacteria endocarditis became atypical when consolidated with other conditions such as tuberculosis (TB). Especially, the symptoms of bacteria endocarditis (BE) which were hidden behind the TB fever often lead to misdiagnosis and missed diagnosis. CASE PRESENTATION: A 56-year-old male with thoracic vertebra bone TB history presented with low-grade fever, shortness of breath and cardiac souffle. After conventional antibiotic therapy and strengthen anti-tuberculosis treatment condition did not be improved...

BACKGROUND: Primary cardiac angiosarcomas are rare, but they are the most aggressive type of primary cardiac neoplasms. When patients do present, it is with advanced pulmonary and/or cardiac symptoms. Therefore, many times the correct diagnosis is not made at the time of initial presentation. These patients have metastatic disease and the vast majority of these patients die within a few months after diagnosis. Currently the treatment choices are limited and there are no targeted therapies available...

PURPOSE: Unlike echocardiography which can quantify both LV filling and ejection, cine steady state free precession sequence (SSFP)-despite its high intrinsic signal and contrast to noise ratio, accuracy and precision of volume measurements-, is mostly relegated to quantifying LV ejection. The steady-state requirement typically constrains SSFP sequence to a breathhold (and limited temporal resolution). We describe: (a) free breathing cine SSFP approach that meets the SS requirement allowing high frame rate acquisition, (b) two MRI indices based on time-LV volume (TV) change during filling and compare against echocardiagraphic diastolic index (E/A ratio), and (c) evaluate the effect of temporal resolution on: LV volumes; ejection and filling rates; and normalized indices of systolic and diastolic function...

Clozapine-related pericarditis is a rare side effect of the drug. We reported the clinical cases of two women, aged 22 and 28 years, affected by schizophrenia with pericarditis symptoms related to clozapine treatment of 200 mg/day. Clozapine was discontinued in both patients, resulting in normalization of the ECG changes, and echocardiography confirmed the progressive disappearance of the pericardial effusion. Interestingly, while inflammatory indices and pro-brain natriuretic peptide (pro-BNP) plasma levels were high in both patients, only one of them showed tachycardia, subjective chest pain, shortness of breath and dyspnea, with a clinical symptomatology suggesting a cardiac involvement...

Delayed cardiac tamponade (DCT) is a rare and life-threatening complication of catheter ablation performed as a treatment of atrial fibrillation, with few cases described in the medical literature. We present the case of a 57year-old man presenting with DCT 61days following a catheter ablation procedure. To the best of our knowledge, this is the most delayed case of cardiac tamponade (CT) following catheter ablation described in the literature. We also discuss the importance of point of care ultrasound (POCUS) in the diagnosis and treatment of CT...

A 78-year-old man was admitted to the authors' hospital with a short history of shortness of breath and pyrexia. He had long-standing moderate mitral regurgitation and stable coronary artery disease. Blood cultures grew Abiotrophia defectiva coccobaccili. Transesophageal echocardiography confirmed the diagnosis of mitral valve endocarditis that necessitated treatment with intravenous benzylpenicillin and gentamicin for six weeks. At nine days after admission the patient developed several episodes of self-limiting monomorphic ventricular tachycardia, without ischemic cardiac pain, associated with hemodynamic compromise requiring treatment with intravenous amiodarone and inotropic support in the Intensive Care Unit...

INTRODUCTION: Troponins are known to be released in response to cardiac damage and therefore are the biomarkers of choice for the early diagnosis of acute myocardial infarction (AMI), improving outcome in patients presenting with chest pain. However, false results can occur due to interference from other substances in the blood. CASE: A 52-year-old male with a past medical history of alcohol abuse, hypertension, and coronary artery bypass graft at age 34 with normal stress test 2 years before presented to the emergency department (ED) complaining of 1 day of non-exertional chest pain with radiation to the neck and left arm...

BACKGROUND: Recently, the symptom of bendopnea, that is, shortness of breath when bending forwards such as when putting on shoes, has been described in heart failure patients and found to be associated with higher ventricular filling pressures, particularly in the setting of low cardiac index. However, it is not known whether bendopnea is associated with clinical outcomes. METHODS: In a prospective convenience sample of 179 patients followed in our heart failure disease management clinic, we determined the presence of bendopnea at the time of enrollment and ascertained clinical outcomes through 1 year of follow-up...

Reduced cerebrovascular reactivity (CVR) was found in patients with recent lacunar infarct. However, its mechanisms were controversial. The breath holding maneuver as vasodilatory stimulus is clinically useful for an estimation of cerebrovasomotor reactivity in well co-operative patients. Patients with lacunar infarct have no higher cortical dysfunction and remain well co-operation. The breath holding maneuver is feasible and safe to perform in patients with lacunar infarct. Autonomic nervous system regulates systemic vascular activity...

Acute pericarditis is an acute inflammatory disease of the pericardium, which may occur in many different disease states (both infectious and non-infectious). Usually the diagnosis is based on symptoms (chest pain, shortness of breath), electrocardiographic changes (ST elevation), physical examination (pericardial friction rub) and elevation of cardiac biomarkers. It may occur in isolation or be associated with an underlying inflammatory disorder. In routine clinical practice, acute pericarditis can be associated with myocarditis due to their overlapping etiologies...

Since the pioneering studies of the 1960s, heart rate variability (HRV) has become an increasingly used non-invasive tool for examining cardiac autonomic functions and dysfunctions in various populations and conditions. Many calculation methods have been developed to address these issues, each with their strengths and weaknesses. Although, its interpretation may remain difficult, this technique provides, from a non-invasive approach, reliable physiological information that was previously inaccessible, in many fields including death and health prediction, training and overtraining, cardiac and respiratory rehabilitation, sleep-disordered breathing, large cohort follow-ups, children's autonomic status, anesthesia, or neurophysiological studies...

A 48 years old male presented to clinic with 12 months of low grade fever with shortness of breath which has progressively worsened with no associated weight loss, night sweats or loss of appetite. There was no prior history of chronic illness before the current illness. Laboratory workup revealed a high white blood cell count with predominant eosinophils. Chest X-ray was normal. Transthoracic echocardiography and Cardiac Magnetic Resonance showed biventricular thrombi. On further extensive workup the findings were consistent with hypereosinophilic syndrome...

OBJECTIVE: During an acute myocardial infarction, patients often use denial as a coping mechanism which may provide positive mood regulating effects but may also prolong prehospital delay time (PHD). However, empirical evidences are still sparse. METHODS: This cross-sectional study included 533 ST-elevated myocardial infarction (STEMI) patients from the Munich Examination of Delay in Patients Experiencing Acute Myocardial Infarction (MEDEA) study. Data on sociodemographic, clinical and psycho-behavioral characteristics were collected at bedside...

Idiopathic dilatation of pulmonary arteries (IDPA) is a rare abnormality of pulmonary arteries, the reported incidence in literature being as low as 0.007% in autopsy samples. With the improvement in diagnostic modalities, antemortem diagnosis of IDPA has been increasingly established by excluding diseases that induce pulmonary arterial enlargement. Here, we present a rare case of idiopathic dilatation of the pulmonary artery admitted with shortness of breath where IDPA was diagnosed as an incidental finding using computed tomography pulmonary angiography and cardiac catheterization...

The new percutaneous Impella CP (Cardiac Power; Abiomed, Inc., Danvers, MA) was designed to provide a higher level of support than Impella 2.5 (Abiomed, Inc.). We present the first documented case of a patient that was transitioned from the Impella 2.5 to Impella CP. A 48-year-old male patient with no medical history was transferred to our institution with a one day history of worsening shortness of breath. The patient was unstable and found to have monomorphic ventricular tachycardia at 220 beats/min that was cardioverted to normal sinus rhythm...
