Review
Since the nationally televised cardiac arrest of American National Football League player Damar Hamlin in January 2023, commotio cordis has come to the forefront of public attention. Commotio cordis is defined as sudden cardiac arrest due to direct trauma to the precordium resulting in ventricular fibrillation or ventricular tachycardia. While the precise incidence of commotio cordis is not known due to a lack of standardized, mandated reporting, it is the third most common cause of sudden cardiac death in young athletes, with more than 75% of cases occurring during organized and recreational sporting events. Given that survival is closely tied to how quickly victims receive cardiopulmonary resuscitation and defibrillation, it is crucial to raise awareness of commotio cordis so that athletic trainers, coaches, team physicians, and emergency medical personnel can rapidly diagnose and treat this often-fatal condition. Broader distribution of automated external defibrillators in sporting facilities as well as increased presence of medical personnel during sporting events would also likely lead to higher survival rates.

Myocardial contusion should be suspected in a selected patient group with blunt thoracic trauma, who have elevated troponin, ECG changes and/or haemodynamical instability. Echocardiography is useful for direct visualisation of possible complications. In stable conditions, MRI allows for good visualisation of the heart and can confirm a suspected myocardial contusion as well as demonstrate the extent of myocardial damage. Based on the present literature, the authors developed a diagram for the diagnostic approach of a patient with suspected myocardial contusion.

Review
Blunt cardiac injury (BCI) encompasses a wide spectrum, from occult and inconsequential contusion to rapidly fatal cardiac rupture. A small percentage of patients present with abnormal electrocardiogram or shock, but most are initially asymptomatic. The potential for sudden dysrhythmia or cardiac pump failure mandates consideration of the presence of BCI, including appropriate monitoring and management. In this review, we will present what you need to know to diagnose and manage BCI.

Review
Commotio cordis is a rare but life-threatening condition characterized by sudden cardiac arrest resulting from a blunt chest impact. While commotio cordis has traditionally been associated with sports-related activities, a significant proportion of cases occur in non-sport-related settings, such as assaults, motor vehicle accidents (MVAs), and daily activities. This critical review examines the epidemiology, clinical characteristics, and outcomes of non-sports-related commotio cordis cases, highlighting the need for increased awareness and improved management in these contexts. The review analyzes existing literature, drawing attention to the demographics of non-sports-related cases, which predominantly affect adolescents and young adults, with males being the primary demographic. In contrast to sport-related cases, non-sports-related commotio cordis cases exhibit a wider age range and a higher proportion of female subjects. Mortality rates are significantly higher in non-sports-related commotio cordis cases, largely due to lower rates of cardiopulmonary resuscitation (CPR), limited access to automated external defibrillators (AEDs), and delayed initiation of resuscitative efforts compared to sport-related incidents. This underscores the critical importance of increasing awareness and preparedness in non-sport-related settings. To mitigate the risks associated with non-sports-related commotio cordis, efforts should focus on early recognition of the condition, timely administration of CPR, and the widespread availability and accessibility of AEDs in various environments. Enhanced awareness and education can potentially lead to a reduction in mortality and improved outcomes for individuals affected by commotio cordis outside of sports-related activities. In conclusion, commotio cordis is not exclusive to sports and presents a significant health risk in non-sport-related scenarios. This review emphasizes the urgent need for increased awareness, preparedness, and resuscitation measures in non-sports contexts to address the higher mortality associated with these cases.

JACC. Clinical Electrophysiology Aug 2023Commotio cordis is an increasingly recognized cause of sudden cardiac death. Although commonly linked with athletes, many events occur in non-sport-related settings.
BACKGROUND
Commotio cordis is an increasingly recognized cause of sudden cardiac death. Although commonly linked with athletes, many events occur in non-sport-related settings.
OBJECTIVES
The goal of this study was to characterize and compare non-sport-related vs sport-related commotio cordis.
METHODS
PubMed and Embase were searched for all cases of commotio cordis from inception to January 5, 2022.
RESULTS
Of 334 commotio cordis cases identified, 121 (36%) occurred in non-sport-related contexts, which included assault (76%), motor vehicle accidents (7%), and daily activities (16%). Projectiles were implicated significantly less in non-sport-related events (5% vs 94%, respectively; P < 0.001). Nonprojectile etiologies in non-sport-related events mostly consisted of impacts with body parts (79%). Both categories affected similar younger aged demographic (P = 0.10). The proportion of female victims was significantly higher in non-sport-related events (13% vs 2%, respectively; P = 0.025). Mortality was significantly higher in non-sport-related events (88% vs 66%, respectively; P < 0.001). In non-sport-related events, rates of cardiopulmonary resuscitation (27% vs 97%, respectively; P < 0.001) and defibrillation (17% vs 81%, respectively; P < 0.001) were both lower and resuscitation was more commonly delayed beyond 3 min (80% vs 5%, respectively; P < 0.001).
CONCLUSIONS
Commotio cordis occurs across a spectrum of non-sport-related settings including assault, motor vehicle accidents, and daily activities. Both categories affected a younger and male-predominant demographic. Mortality is higher in non-sport-related commotio cordis, likely owing to lower rates of cardiopulmonary resuscitation, defibrillation, automated external defibrillator availability, and extended time to resuscitation. Increased awareness of non-sport-related commotio cordis is essential to develop a means of prevention and mortality reduction, with earlier recognition and prompt resuscitation measures.

Myocardial contusion is a rare and potentially fatal complication of chest trauma. There is no unique definition for this entity: some authors define myocardial contusion as a mild increase in cardiac biomarkers in the context of chest trauma, while for others the diagnosis requires evidence of pathologic findings at cardiac imaging. Consequently, the real incidence of myocardial contusion remains unknown, varying in reports between 8% and 71%. We describe a case of cardiac contusion secondary to a low-energy blunt chest trauma, manifesting as persistent ST-elevation associated with elevation of myocardial necrosis markers, with consequent myocardial stunning of the right ventricular free wall. As there is no consensus regarding the diagnostic pathway, it is essential to integrate first-level exams (ECG and laboratory findings) with cardiac magnetic resonance imaging, to define the presence of cardiac contusion and its extent, particularly if the echocardiographic data are unconclusive.

Inhaled nitric oxide (iNO) is an advanced therapy typically managed by physicians and respiratory therapists in order to increase arterial oxygenation and decrease pulmonary arterial pressure. The Johns Hopkins Lifeline Critical Care Transportation Program (Lifeline) initiated a novel nurse-managed iNO protocol in order to optimize the oxygenation of critically ill patients during interfacility transport. This study was a retrospective chart review of adverse events associated with iNO initiation or continuation by Lifeline on patients transported from March 1, 2020, to August 1, 2022. Basic demographic data and adverse events were recorded. Recorded adverse events included hypotension defined as a mean arterial pressure (MAP) < 65 mm Hg, hypoxemia defined as a decrease of ≥ 10% arterial oxygenation saturation measured by pulse oximetry, new bradycardia or tachyarrhythmia, nitrogen dioxide (NO) levels greater than 1.0 ppm, methemoglobinemia, and cardiac arrest. Fifteen patients were diagnosed with SARS-CoV-2 infection, of which one also had pulmonary emboli, 2 had bacterial pneumonia, 1 suffered cardiogenic shock from occlusive myocardial infarction and were on VA-ECMO, and 2 had significant thoracic trauma resulting in pulmonary contusions and hemopneumothorax. iNO was continued on 10 patients and initiated on 8 patients, 2 of whom were transitioned from inhaled epoprostenol. Hypotension occurred in 3 (16.7%) patients and one (5.56%) of the hypotensive patients subsequently went on to experience new atrial fibrillation with vasopressor titration. No patients developed worsening hypoxemia, elevated NO levels, methemoglobinemia, or suffered cardiac arrest. All 3 patients who experienced hypotension were already on vasopressor support and the hypotension resolved with medication titration. This study shows that iNO administration can be safely managed by appropriately trained nurses.

Observational Study
BACKGROUND
One of the worst types of severe chest injuries seen by clinicians is flail chest. This study aims to measure the overall mortality rate among flail chest patients and then to correlate mortality with several demographic, pathologic, and management factors.
METHODOLOGY
A retrospective observational study tracked a total of 376 flail chest patients admitted to the emergency intensive care unit (EICU) and surgical intensive care unit (SICU) at Zagazig University over 120 months. The main outcome measurement was overall mortality. The secondary outcomes were the association of age and sex, concomitant head injury, lung and cardiac contusions, the onset of mechanical ventilation (MV) and chest tubes insertion, the length of mechanical ventilation and ICU stay in days, injury severity score (ISS), associated surgeries, pneumonia, sepsis, the implication of standard fluid therapy and steroid therapy, and the systemic and regional analgesia, with the overall mortality rates.
RESULTS
The mortality rate was 19.9% overall. The shorter onset of MV and chest tube insertion, and the longer ICU, and hospital length of stay were noted in the mortality group compared with the survived group (P-value less than 0.05). Concomitant head injuries, associated surgeries, pneumonia, pneumothorax, sepsis, lung and myocardial contusion, standard fluid therapy, and steroid therapy were significantly correlated with mortality (P-value less than 0.05). MV had no statistically significant effect on mortality. Regional analgesia (58.8%) had a significantly higher survival rate than intravenous fentanyl infusion (41.2%). In multivariate analysis, sepsis, concomitant head injury, and high ISS were independent predictors for mortality [OR (95% CI) = 568.98 (19.49-16613.52), 6.86 (2.86-16.49), and 1.19 (1.09-1.30), respectively].
CONCLUSION
The current report recorded mortality of 19.9% between flail chest injury patients. Sepsis, concomitant head injury, and higher ISS are the independent risk factors for mortality when associated with flail chest injury. Considering restricted fluid management strategy and regional analgesia may help better outcome for flail chest injury patients.

Traumatic coronary artery occlusion and dissection is an exceedingly rare complication of blunt cardiac injury (BCI), though it has been previously noted in a number of case reports. However, it can also lead to heart transplant, which to our knowledge has not been previously described in the literature. We present a case of a healthy 24-year-old man without significant past medical history who was in a motorcycle accident, resulting in sternal fracture and BCI. He was ultimately found to have thrombotic occlusion and dissection of his left anterior descending artery (LAD), requiring mechanical thrombectomy and drug-eluting stent, as well as subsequent hospitalizations and operations due to various complications. It was suspected that he went into ventricular fibrillation and had a second motorcycle collision, resulting in cardiogenic shock. Ultimately, his progression of ischemic cardiomyopathy and mitral regurgitation led to the need for heart transplant. Blunt cardiac injury with myocardial contusion has such a broad range of pathologies. It is essential that patients with these injury patterns raise a high level of suspicion for BCI and are followed closely with appropriate diagnostic testing and rapid intervention for best possible outcomes.
