BACKGROUND: Cardiotoxicity is a well-known adverse effect of various chemotherapeutic agents that can be monitored by echocardiography. A decrease in left ventricular ejection fraction (LVEF) triggers consideration for therapy modification or interruption. The aim of this study was to evaluate how variability in LVEF estimates computed using three-dimensional echocardiography could influence cardiotoxicity onset detection. METHODS: One hundred eighty one patients with breast cancer treated with anthracycline and trastuzumab were analyzed...

Post-traumatic fluid management is a widely debated topic. No best-practice consensus exists. Adverse outcomes such as acute kidney injury or volume overload are common. Continuous renal replacement therapy (CRRT) is an adjunct therapy for severe acute renal failure and volume overload, but is costly and not without risk. Hemodynamic transesophageal echocardiography (hTEE) is widely accepted as a reliable way to monitor volume status of intensive care unit (ICU) patients. Although data exist evaluating hTEE and CRRT independently, there is a lack of research mutually inclusive of the two...

This paper proposes a robotic Transesophageal Echocardiography (TOE) system concept for Catheterization Laboratories. Cardiovascular disease causes one third of all global mortality. TOE is utilized to assess cardiovascular structures and monitor cardiac function during diagnostic procedures and catheter-based structural interventions. However, the operation of TOE underlies various conditions that may cause a negative impact on performance, the health of the cardiac sonographer and patient safety. These factors have been conflated and evince the potential of robot-assisted TOE...

REVIEW
Kathlyn J Ronaldson
Myocarditis occurs in about 3% of those initiated on clozapine but monitoring reduces the risk of serious outcome. Cardiomyopathy may develop after myocarditis, or from prolonged tachycardia. Monitoring using echocardiography is not deemed cost effective. Tachycardia, orthostatic hypotension and reduced heart rate variability are a group of clozapine-related adverse effects associated with autonomic dysfunction and may have serious consequences in the long term. Elevated heart rate and poor heart rate variability can be treated with a β-blocker or a non-dihydropyridine calcium channel blocker, while orthostatic hypotension can be alleviated by increased fluid intake and abdominal binding, but may require pharmacological intervention...

Chronic hypocalcemia, irrespectively of its etiology, can lead to severe impairment of the left ventricular (LV) contractility manifesting as dilated cardiomyopathy, usually defined as hypocalcemic cardiomyopathy (hypocaCM). This rarely diagnosed type of heart failure (HF), can be completely reversible, when treated properly with calcium and vitamin D supplementation or, in some subjects, with human recombinant parathormone. A CASE REPORT: The authors present a case of a 60-year-old male admitted with advanced pulmonary congestion, recurrent pulmonary edema and pleural effusion...

BACKGROUND: Intestinal transplantation (ITx) is the definitive therapy for patients suffering from intestinal failure. Previous published reports suggest that these cases should be managed peri-operatively with the same intensive monitors and techniques as in liver transplantation. METHODS: We retrospectively reviewed the anesthetic management of sixty-seven isolated intestinal, intestinal-pancreas and intestinal-kidney transplants over the previous decade (2005-2015) in our tertiary care institution...

Contemporary cancer management has increased the overall number of cancer survivors, but cardiotoxicity remains a subject of concern, which is a major cause of noncancer mortality among survivors. Among the potential cardiovascular complications, left ventricular (LV) systolic dysfunction is a poor prognostic factor. The importance of its early detection is based on the principle that the likelihood of response to heart failure (HF) treatment is temporally related to the initiation of HF treatment. For these reasons, cardiac monitoring is commonly applied in general practice, based on serial measurements of LV ejection fraction (LVEF); transthoracic echocardiography (TTE) is generally used...

BACKGROUND: Extra-renal involvement in hemolytic uremic syndrome (HUS) includes gastrointestinal, pancreatic, hepatic, neurological and cardiac manifestations. The current 3-5% mortality rate in HUS patients is primarily attributed to complications related to the central nervous system and the heart. In this brief report, we illustrate that severe cardiac involvement in a patient with HUS is potentially reversible using cardiopulmonary bypass as rescue. CASE-DIAGNOSIS/TREATMENT: A 12-year-old boy was diagnosed with enterohemorrhagic Escherichia coli-induced HUS related to E...

Patients presenting with acute chest pain are a challenge for attending physicians in private practice and specialists for emergency and acute medicine in hospitals because a wide spectrum of diagnoses may be the cause, ranging from acute myocardial infarction (AMI) to harmless muscular tension. The evaluation of patients with acute chest pain follows basic principles independent of the setting: A thorough clinical investigation by the responsible physician including medical history and physical examination, followed by a 12-channel electrocardiogram (ECG) and further focused diagnostics...

Gyrocardiography (GCG) is a new non-invasive technique for assessing heart motions by using a sensor of angular motion - gyroscope - attached to the skin of the chest. In this study, we conducted simultaneous recordings of electrocardiography (ECG), GCG, and echocardiography in a group of subjects consisting of nine healthy volunteer men. Annotation of underlying fiducial points in GCG is presented and compared to opening and closing points of heart valves measured by a pulse wave Doppler. Comparison between GCG and synchronized tissue Doppler imaging (TDI) data shows that the GCG signal is also capable of providing temporal information on the systolic and early diastolic peak velocities of the myocardium...

BACKGROUND: Metabolic syndrome (MetS) is an endocrinological disease with both metabolic and physiological components. Previous studies have shown a relationship between MetS and left ventricular (LV) dysfunction. A fragmented QRS (fQRS) is a reliable electrocardiogram (ECG) finding with the importance of an indicator of myocardial fibrosis and scarring. In this study, we examined the utility of speckle tracking echocardiography (STE) in assessing LV function in MetS patients with fQRS...

Minimally invasive mitral valve repair has become standard. We hypothesized that reproducible water testing with less air contaminations may help achieve successful repair and prevent air embolism. We used a long shaft irrigation device connected to an infuser pump to water test mitral valve repair in 104 consecutive patients with severe mitral regurgitation due to type II mitral valve dysfunction. All patients underwent mitral valve repair via small right thoracotomy. Water testing was performed by simultaneously monitoring root pressure to confirm valve competence and adequate leaflet coaptation with suitable pressure...

Takotsubo cardiomyopathy (TCM) is a form of transient heart failure that clinically mimics acute coronary syndrome and is characterized by left ventricular wall motion abnormalities. The pathophysiology of TCM is not well established. TCM is often preceded by emotional or physical stress and may occur after surgery. We present 3 cases of TCM occurring after head and neck reconstructive surgery. Echocardiography plays a central role in the diagnosis of TCM. Left ventricular wall motion abnormalities extend beyond the territory of a single coronary artery...
