Adrenergic myocarditis is an uncommon presentation of pheochromocytoma and extremely rare cause of de novo acute heart failure (AHF). We present a case of a 31-year-old Caucasian woman with a history of hypertension and recurrent occipital headaches who was admitted to the emergency department due to severe de novo AHF presenting as pulmonary edema and cardiogenic shock. During the hospital admission the patient experienced asystolic cardiac arrest and was successfully resuscitated, intubated, and mechanically ventilated...

BACKGROUND: Pulmonary embolism can be difficult to diagnose, particularly in those who are hemodynamically unstable and cannot be imaged to confirm the diagnosis. Echocardiography can allow for rapid assessment of patients in shock, but requires adequate transthoracic windows to obtain clinically useful information. Emergency physician-performed transesophageal echocardiography (TEE) may be a useful tool when transthoracic echocardiography fails. CASE REPORT: An 86-year-old woman presented to the emergency department after a fall at home...

A 19-year-old male patient was admitted to our institute with dyspnea. His medical history had no rheumatic fever or infective endocarditis. Physical examination revealed a diastolic murmur over the aortic area, rales of bilateral lungs. Bedside transthoracic echocardiography (TTE) revealed a severe aortic regurgitation (AR) without aortic valve stenosis and a moderately dilated left ventricle accompanied by an ejection fraction of 55%. The aortic valve could not be clearly demonstrated as either bicuspid or tricuspid...

This paper develops a method for the minimally invasive, beat-by-beat estimation of the left ventricular pressure-volume loop. This method estimates the left ventricular pressure and volume waveforms that make up the pressure-volume loop using clinically available inputs supported by a short, baseline echocardiography reading. Validation was performed across 142,169 heartbeats of data from 11 Piétrain pigs subject to two distinct protocols encompassing sepsis, dobutamine administration and clinical interventions...

The so-called point-of-care ultrasound (POCUS) is of increasing importance for diagnostics and therapy control in intensive care medicine. Based on focused thorax sonography, echocardiography, and abdominal sonography, the most important working and differential diagnoses can be demonstrated or excluded depending on the leading symptom. Sonographic-based algorithms allow a structured evaluation especially of patients with the common leading symptoms dyspnea and thoracic pain.

We report two cases of a quadricuspid aortic valve with severe aortic incompetence. Both patients presented with dyspnea on exertion. Their physical examinations demonstrated wide pulse pressures with diastolic murmurs. Bedside transthoracic Doppler echocardiography revealed preserved left ventricular systolic function and possible quadricuspid aortic valve with severe aortic incompetence in both patients. We proceeded with transesophageal echocardiography that confirmed a quadricuspid aortic valve with severe aortic incompetence in both patients...

BACKGROUND: Asymptomatic left ventricular (LV) dysfunction is highly prevalent in type 2 diabetes patients. Unlike the other hypoglycemic drugs, SGLT2 inhibitors have shown potential benefits for reducing cardiovascular death and risk factors, aside from lowering plasma glucose levels. With this study we aim at determining whether the treatment with empagliflozin is associated with an improvement in LV functions in diabetic patients with asymptomatic LV dysfunction against Sitagliptin, which is presumably neutral on myocardial function...

Lorenzo De Marchi, Massimiliano Meineri
Ultrasound (US) performed at the point of care has found fertile ground in perioperative medicine. In the hands of anesthesiologists, transesophageal echocardiography (TEE) has become established as a powerful diagnostic and monitoring tool in the perioperative care of cardiac and non-cardiac patients. A number of point-of-care US (POCUS) applications are relevant to perioperative care, including airway, cardiac, lung and gastric US. Although guidelines exist to define the scope of practice for basic and advanced TEE, there remains a lack of such guidelines for perioperative point-of-care ultrasound (POCUS), despite a number of recent calls for action in the academic anesthesia community...

REVIEW
Yogen Singh
Hemodynamic instability and inadequate cardiac performance are common in critically ill children. The clinical assessment of hemodynamic status is reliant upon physical examination supported by the clinical signs such as heart rate, blood pressure, capillary refill time, and measurement of the urine output and serum lactate. Unfortunately, all of these parameters are surrogate markers of cardiovascular well-being and they provide limited direct information regarding the adequacy of blood flow and tissue perfusion...

BACKGROUND: Drugs acting on the cardiovascular and central nervous system often display relatively fast clinical responses, which may differ in neonates compared to children and adults. Introduction of bedside monitoring tools might be of additional value in the pharmacodynamic (PD) assessment of such drugs in neonates. METHODS: We aim to provide an overview of the frequently used monitoring tools to assess drug effects on the hemodynamic status as well as the cerebral circulation, oxygenation and cerebral metabolism in neonates...

INTRODUCTION: Aortic dissection is a life threatening disease and is usually accompanied by a high rate of mortality and morbidity. Here we present a case report in which intraoperative tranesophageal echocardiography was used for intraoperative assessments of thoracic aortic dissection due to cocaine abuse. CASE PRESENTATION: A 45- year- old male was admitted to a university hospital due to severe chest pain. He was suffering from severe excruciating chest pain that had started after a psychological stress, leading to heavy cocaine abuse...

Training adult learners to use ultrasound in clinical practice relies on the ability of the learner to apply visuospatial concepts to the anatomy of the human body. We describe a visuospatial trainer that replicates the housing of an ultrasound transducer, through which a linear laser projects light in the same plane and orientation as the ultrasonic sound waves. We use this trainer in combination with a porcine heart dissection laboratory to teach bedside cardiac ultrasound and transthoracic echocardiography (TTE)...

BACKGROUND: The European Association of Cardiology (ESC) Guidelines on the diagnosis and treatment of acute heart failure (AHF) indicate prompt therapy initiation and performance of relevant investigations as paramount. Specifically, echocardiography prior to treatment is advocated only with hemodynamic instability, and the evaluation of clinical signs of peripheral perfusion and congestion is suggested as guidance for early interventions. Given the growing body of evidence on the diagnostic/monitoring capabilities of bedside ultrasound (including focused cardiac ultrasound, comprehensive echocardiography, lung ultrasound), we discuss the potential benefit of an integrated clinical/ultrasound approach at the very early stages of acute heart failure...

METHODS: Ventilated patients in sinus rhythm requiring advanced hemodynamic assessment for septic shock were included in this prospective multicenter descriptive study. Patients were assessed successively using TPT and CCE in random order. Data were interpreted independently at bedside by two investigators who proposed therapeutic changes on the basis of predefined algorithms...

Abimbola O Faloye, Raphael Y Gershon
Traumatic ventral septal defect may be sustained after either blunt force or penetrating trauma to the chest. Severity ranges from asymptomatic to acute decompensated heart failure. Our patient suffered a stab wound to the chest and was initially taken to the operating room for repair of a lacerated right ventricle. Subsequent postoperative hemodynamic deterioration prompted a bedside transthoracic echocardiogram, which failed to identify causal factors. A transesophageal echocardiogram performed immediately after ventral septal defect was demonstrated...
