A 74-year-old female underwent an uneventful bilateral thoracoscopic maze procedure for persistent atrial fibrillation with continuous transesophageal echocardiographic (TEE) guidance. She presented six weeks later with persistent fever and focal neurological signs. Computed tomography of the thorax revealed air in the posterior LA, raising suspicion for an abscess versus an atrioesophageal fistula (AEF). Before undergoing an exploratory median sternotomy, an esophagogastroduodenoscopy (EGD) was performed by the surgeon to check for any esophageal pathology...

Acute traumatic spinal cord injury (SCI) affects more than 250,000 people in the USA, with approximately 17,000 new cases each year. It continues to be one of the most significant causes of trauma-related morbidity and mortality. Despite the introduction of primary injury prevention education and vehicle safety devices, such as airbags and passive restraint systems, traumatic SCI continues to have a substantial impact on the healthcare system. Over the last three decades, there have been considerable advancements in the management of patients with traumatic SCI...

The kidneys are densely innervated with renal efferent and afferent nerves to communicate with the central nervous system. Innervation of major structural components of the kidneys, such as blood vessels, tubules, the pelvis, and glomeruli, forms a bidirectional neural network to relay sensory and sympathetic signals to and from the brain. Renal efferent nerves regulate renal blood flow, glomerular filtration rate, tubular reabsorption of sodium and water, as well as release of renin and prostaglandins, all of which contribute to cardiovascular and renal regulation...

BACKGROUND AND PURPOSE: The diverse causes of right-sided heart failure (RHF) include, among others, primary cardiomyopathies with right ventricular (RV) involvement, RV ischemia and infarction, volume loading caused by cardiac lesions associated with congenital heart disease and valvular pathologies, and pressure loading resulting from pulmonic stenosis or pulmonary hypertension from a variety of causes, including left-sided heart disease. Progressive RV dysfunction in these disease states is associated with increased morbidity and mortality...

The emergence of functional neuroimaging has dramatically accelerated our understanding of the human mind. The advent of functional Magnetic Resonance Imaging paved the way for the next decades' major discoveries in neuroscience and today remains the "gold standard" for deep brain imaging. Recent improvements in imaging technology have been somewhat limited to incremental innovations of mature techniques instead of breakthroughs. Recently, the use of ultrasonic plane waves transmitted at ultrafast frame rates was shown to highly increase Doppler ultrasound sensitivity to blood flows in small vessels in rodents...

BACKGROUND: Dexmedetomidine (Dex) is an attractive agent for procedural sedation due to its unique pharmacodynamic profile, specifically affording predictable sedation without concurrent respiratory depression. However, Dex has previously been reported to prevent or terminate arrhythmias. The purpose of this study was to investigate paroxysmal supraventricular tachycardia (PSVT) inducibility and homeostatic stability during electrophysiology studies (EPSs) and ablation when a standardized Dex protocol was used as the primary sedation agent...

An update of the S3- guidelines for treatment of cardiac surgery patients in the intensive care unit, hemodynamic monitoring and cardiovascular system was published by the Association of Scientific Medical Societies in Germany (AWMF) in January 2018. This publication updates the guidelines from 2006 and 2011. The guidelines include nine sections that in addition to different methods of hemodynamic monitoring also reviews the topic of volume therapy as well as vasoactive and inotropic drugs. Furthermore, the guidelines also define the goals for cardiovascular treatment...

Background: Traditionally, laparotomy/thoracotomy is the standard approach for thoracoabdominal injuries. However, it has a non-therapeutic rate of 12-40% and 40% morbidity. Laparoscopy, as a diagnostic and therapeutic modality, has evolved to be integral to general and subspecialty surgeons in the management of patients. However, its use in the field of trauma surgery has been limited. We present a case of traumatic diaphragmatic injury from a low velocity penetrating wound successfully repaired through laparoscopic approach...

PURPOSE OF REVIEW: Many patients suffer from either persistent right ventricular failure (RVF) at the time of left ventricular assist device (LVAD) or have ongoing symptoms consistent with RVF during chronic mechanical circulatory support. The lack of long-term right ventricular assist devices (RVADs) has limited the impact that mechanical circulatory support can provide to patients with biventricular failure. We aim to review the entire spectrum of RVF in patients receiving LVADs and reflect on why this entity remains the Achilles' heel of LVAD therapy...

PURPOSE OF REVIEW: We review the recent advances in physiologic monitoring during cardiac arrest and offer an evidence-based framework for prioritizing physiologic targets during cardiopulmonary resuscitation (CPR). RECENT FINDINGS: Current CPR guidelines recommend a uniform approach for all patients in cardiac arrest, but newer data support a precision strategy that uses the individual patient's physiology to guide resuscitation. Coronary perfusion pressure and arterial DBP are associated with survival outcomes in recent animal and human studies...

We present a rare case of traumatic bilateral asymmetric hip dislocation with pelvic fractures and a traumatic diaphragmatic hernia. A 53-year-old machinist was transferred to our emergency department with the suspicion of a bilateral hip dislocation after he was trapped between an elevator and the roof. Immediate closed reduction of the hips was not performed because of the expected risk of increasing hemodynamic instability with muscular relaxation. An emergent full-body computed tomography (CT) scan was made to assess injuries with need for further operative treatment...

We present a 40 year old asymptomatic man with mild left main artery narrowing who demonstrated extreme discordance between symptom presentation and ischemic burden i.e. visual (angiographic) and ischemic (functional) mismatch. The use of an appropriately selected screening stress test can lead to an appropriate decision for revascularization, supported by landmark risk assessment documents and revascularization trials.

Atrial fibrillation (AF) is the most common arrhythmia encountered in the intensive care unit. Pre-existing AF is highly prevalent among older patients with chronic conditions who are at risk for critical illness, while new-onset AF can be triggered by accelerated atrial remodeling and arrhythmogenic triggers encountered during critical illness. The acute loss of atrial systole and onset of rapid ventricular rates that characterize new-onset AF often lead to decreased cardiac output and hemodynamic compromise...

AIMS: Avoiding propofol in patients with Brugada syndrome has been suggested because of the theoretical risk of provoking ventricular arrhythmias, although propofol may be selected for conscious sedation during electrophysiological procedures in catheterization laboratories. This study aimed to document peri-procedural electrocardiographic changes and adverse events in patients with Brugada syndrome undergoing implantable cardioverter defibrillator (ICD) implantation using propofol sedation...

Due to advancing age and increasing comorbidities, the current population has a higher incidence of complex coronary artery disease, often without surgical options for revascularization. In this setting, hemodynamic support devices are an important adjunct in the interventionist's toolbox as they allow for a safer, more effective procedure. The following paper reviews the indications of various available mechanical support devices, highlights their clinical data and technical parameters, and offers a practical approach towards appropriate patient and device selection...

PURPOSE OF REVIEW: To review the different methods available for the assessment of cardiac output (CO) and describe their specific indications in intensive care and perioperative medicine. RECENT FINDINGS: In critically ill patients, persistent circulatory shock after initial resuscitation is an indication for the assessment of CO to monitor the response to fluids and vasoactive agents. In patients with circulatory shock associated with right ventricular dysfunction, pulmonary artery hypertension, or acute respiratory distress syndrome, invasive CO monitoring using indicator dilution methods is indicated...

Cardiovascular complications have emerged as the leading cause of death after liver transplantation, particularly among those with advanced liver cirrhosis. Therefore, a thorough and accurate cardiovascular evaluation with clear comprehension of cirrhotic cardiomyopathy is recommended for optimal anesthetic management. However, cirrhotic patients manifest cardiac dysfunction concomitant with pronounced systemic hemodynamic changes, characterized by hyperdynamic circulation such as increased cardiac output, high heart rate, and decreased systemic vascular resistance...

Subclinical leaflet thrombosis (SLT) following transcatheter aortic valve replacement (TAVR) has been increasingly recognized. SLT has the hallmark features of hypo-attenuated leaflet thickening (HALT) on multidetector computed tomography (MDCT), which may result in hypoattenuation affecting motion (HAM). The actual prevalence of this condition is uncertain, with limited observational registries. SLT has caught the attention of the cardiovascular community because of concerns regarding its clinical sequelae, specifically the potential increased incidence of cerebrovascular events...
