ABSTRACT

OBJECTIVE: The use of high-flow nasal cannula (HFNC) oxygen therapy is gaining popularity for the treatment of acute respiratory failure (ARF). However, limited evidence exists regarding the effectiveness of HFNC for hypoxemic ARF in patients with blunt chest trauma (BCT). METHODS: This retrospective analysis focused on BCT patients with mild-moderate hypoxemic ARF who were treated with either HFNC or non-invasive ventilation (NIV) in the emergency medicine department from January 2021 to December 2022. The primary endpoint was treatment failure, defined as either invasive ventilation, or a switch to the other study treatment (NIV for patients in the NFNC group, and vice-versa). RESULTS: A total of 157 patients with BCT (72 in the HFNC group and 85 in the NIV group) were included in this study. The treatment failure rate in the HFNC group was 11.1% and 16.5% in the NIV group - risk difference of 5.36% (95% CI, -5.94-16.10%; P = 0.366). The most common cause of failure in the HFNC group was aggravation of respiratory distress. While in the NIV group, the most common reason for failure was treatment intolerance. Treatment intolerance in the HFNC group was significantly lower than that in the NIV group (1.4% vs 9.4%, 95% CI 0.40-16.18; P = 0.039). Univariate logistic regression analysis showed that chronic respiratory disease, abbreviated injury scale score (chest) (≥3), Acute Physiology and Chronic Health Evaluation II score (≥15), partial arterial oxygen tension /fraction of inspired oxygen (≤200) at 1 h of treatment and respiratory rate (≥32 /min) at 1 h of treatment were risk factors associated with HFNC failure. CONCLUSION: In BCT patients with mild-moderate hypoxemic ARF, the usage of HFNC did not lead to higher rate of treatment failure when compared to NIV. HFNC was found to offer better comfort and tolerance than NIV, suggesting it may be a promising new respiratory support therapy for BCT patients with mild-moderate ARF.

ABSTRACT

Despite being rare, traumatic coronary artery dissection after blunt chest trauma can lead to life-threatening consequences that can be fatal. This case report focuses on a 51-year-old woman who suffered chest trauma at home and was later found to have right coronary artery dissection. This manuscript aims to elucidate the risk factors, diagnostic challenges, and management strategies associated with traumatic coronary artery dissection. This case report emphasizes the evaluation of risk factors, the significance of early detection with appropriate imaging modalities while maintaining high clinical suspicion, and the critical necessity of optimizing patient outcomes in such circumstances.

ABSTRACT

Background: Traumatic pneumocephalus is commonly encountered after basal skull fractures and rarely associated with blunt chest trauma. Here, we report a case of pneumocephalus caused by traumatic pneumothorax and brachial plexus avulsion. Case Presentation: A 20-year-old male was admitted to our hospital following a motorcycle accident with complete paralysis of the right upper limb. 2 days later, follow-up computed tomography revealed a slight right pneumothorax, pneumomediastinum around the neck, and intracranial air without skull fracture. Air migrates into the subarachnoid space through a dural tear caused by a brachial plexus avulsion. The pneumocephalus immediately improved after the insertion of a chest drain. Conclusion: Pneumothorax combined with brachial plexus avulsion could lead to pneumocephalus. Immediate chest drainage might be the best way to stop the migration of air; however, care should be taken to not worsen cerebrospinal fluid leakage.

ABSTRACT

Background The thoracic ultrasound (TUS) is a monitoring tool that has gained worldwide popularity in various scenarios, offering the opportunity for dynamic, bedside evaluations. Recent studies indicate that the use of TUS enables the diagnosis of pathologies resulting from blunt chest trauma (BCT), yielding favorable outcomes. This study aimed to compare the utility of TUS versus chest radiography (CXR) in diagnosing pulmonary pathologies resulting from closed-chest traumas. Methodology A prospective cross-sectional study was conducted with a sample of 58 patients diagnosed with BCT who sought emergency care at the "Dr. Luis Razetti" University Hospital in Barcelona, Venezuela, from November 2023 to January 2024. Results Of the patients, 75.9% (n = 44) were male, with an average age of 37.8 years (standard deviation = 18.4 years). Injuries were reported in 8.6% (n = 5) of the patients, including 60% (n = 3) pneumothorax and 40% (n = 2) hemothorax. Ultrasound results coincided with CXR in 94.8% (n = 55) of the cases, with a Cohen's kappa coefficient of 0.9 (95% confidence interval (CI) = 0.642-1.0). TUS demonstrated higher sensitivity than CXR (100% vs. 60%) for detecting hemothorax and pneumothorax in patients with BCT, with an area under the receiver operating characteristic curve of 0.991 (95% CI = 0.968-1.013). Conclusions BCT predominantly occurred in young males, resulting primarily in pneumothorax and hemothorax lesions, detectable with higher sensitivity through TUS compared to CXR. The use of TUS should be considered an essential component of the initial assessment for individuals with BCT.

ABSTRACT

PURPOSE: To explore patient and clinician perceptions of blunt chest trauma management and recovery, when discharged directly home from the Emergency Department (ED). METHODS: This was a qualitative study, completed in a trauma unit in Wales. Blunt chest trauma was defined as an isolated blunt injury to the chest wall, resulting in bruising or rib fractures. Data collection involved semi-structured telephone interviews and focus groups with patients and clinicians respectively. Data analysis was completed using reflexive thematic coding. RESULTS: Twelve patient interviews and three focus groups (23 clinicians) were conducted. In the interviews, seven males and five females participated, with a mean age of 54 years (range 28-74). Clinicians included nurses, doctors, and therapists. Two main themes emerged; 1) the ED experience and 2) recovery once home; each with a number of sub-themes. Results highlighted the significant impact of pain on recovery, and that there is a disjuncture between organisational perspectives of clinicians, and the individual personal perspective of patients. DISCUSSION: Recovery from blunt chest trauma for patients discharged directly home from the ED is a challenging and complex process. Protocol-driven care does not always lead to good patient experience, as it focuses primarily on hospital services and resources.


Recovery from blunt chest trauma is a complex process, leading to poor outcomes including pain and disability.Protocol-driven care of blunt chest trauma does not always lead to a good patient experience.Patients with blunt chest trauma benefit from reassurance that their severity of pain is normal, prior to discharge home from the Emergency Department (ED).Education regarding pacing activity, rest, and reliance on others for a period of time following injury can lead to an improved recovery experience.

ABSTRACT

BACKGROUND: Aortic valve perforation is a rare complication of blunt chest trauma. We report a case of delayed aortic insufficiency presenting several months after trauma. CASE PRESENTATION: A 17-year-old male presented to the emergency department with traumatic brain injuries and blunt chest trauma, but no evidence of cardiac injuries. Three months later, he developed acute heart failure due to severe aortic valve regurgitation with left ventricular dysfunction. A sizable tear in the right coronary cusp caused aortic insufficiency. He was treated successfully by surgical replacement with an aortic bioprosthesis. CONCLUSION: We reported a successful surgical case of valve replacement for delayed aortic valve perforation. Delayed valve perforation should be kept in mind after blunt chest trauma.

ABSTRACT

Sudden death by commotio cordis is rare. It is the consequence of a blunt trauma of the chest overlying the heart. The mechanism is a cardiac arrest by ventricular fibrillation in the absence of grossly or microscopically apparent myocardial injury. It has been reproduced in animals. The first historical case was reported by Giovanni Maria Lancisi in his book "De Subitaneis Mortibus'' published in 1707. Sudden death occurred in a man receiving a powerful blow under the xiphoid cartilage. Lancisi advanced the hypothesis of acute heart failure by a diastolic stand still ("death in diastole'').

ABSTRACT

El trauma es la principal causa de muerte de la población en edad productiva. El abordaje del trauma torácico cerrado todavía es un desafío para el médico de urgencias. Aunque no es una entidad frecuente, se asocia con una alta mortalidad y resultados adversos. El diagnóstico del trauma cerrado de aorta torácica (LCAT) requiere un alto índice de sospecha, dado que los signos y síntomas no son específicos de esta enfermedad (dolor torácico, dolor interescapular, disnea, disfagia, estridor, disfonía). Es importante resaltar que la ausencia de inestabilidad hemodinámica no debe descartar una lesión aórtica. Para su diagnóstico imagenológico se debe tener en cuenta que los rayos X de tórax no tienen el rendimiento adecuado, el patrón de referencia es la angiotomografía y el ecocardiograma transesofágico (ETE) constituye una opción diagnóstica. El manejo incluye líquidos endovenosos y antihipertensivos como medida transitoria, manejo quirúrgico definitivo y, en algunos casos, manejo expectante o diferido. Los pacientes inestables o con signos de ruptura inminente deben ser llevados de manera inmediata a cirugía. El manejo quirúrgico temprano ha impactado en la mortalidad. A pesar de los avances en las técnicas quirúrgicas, la técnica quirúrgica abierta documenta mayor tasa de mortalidad que el manejo endovascular, el cual tiene numerosas ventajas al ser poco invasivo. Esta es una revisión narrativa que destaca algunos aspectos clave sobre los mecanismos de lesión, diagnóstico y manejo inicial del trauma cerrado aorta torácica. Por último, se propone un algoritmo de abordaje de trauma de aorta.


Trauma is the leading cause of death in the productive-age population. Addressing blunt chest trauma is still a challenge for the emergency physician. Although it is not a common entity, it is associated with high mortality and adverse outcomes. The diagnosis of blunt thoracic aortic trauma (LCAT) requires a high index of suspicion, given that the signs and symptoms are not specific to this disease (chest pain, interscapular pain, dyspnea, dysphagia, stridor, dysphonia). It is important to highlight that the absence of hemodynamic instability should not rule out aortic injury. For its imaging diagnosis, it must be taken into account that chest X-rays do not have adequate performance; the reference standard is angiotomography and transesophageal echocardiography (TEE) is a diagnostic option. Management includes intravenous fluids and antihypertensives as a temporary measure, definitive surgical management and, in some cases, expectant or deferred management. Unstable patients or patients with signs of imminent ruptura should be taken immediately to surgery. Early surgical management has impacted mortality. Despite advances in surgical techniques, the open surgical technique documents a higher mortality rate than endovascular management, which has numerous advantages as it is minimally invasive. This is a narrative review that highlights some key aspects about the mechanisms of injury, diagnosis and initial management of blunt thoracic aortic trauma. Finally, an algorithm for addressing aortic trauma is proposed.

ABSTRACT

BACKGROUND: A significant proportion of patients with severe chest trauma require mechanical ventilation (MV). Early prediction of the duration of MV may influence clinical decisions. We aimed to determine early risk factors for prolonged MV among adults suffering from severe blunt thoracic trauma. METHODS: This retrospective, single-center, cohort study included all patients admitted between January 2014 and December 2020 due to severe blunt chest trauma. The primary outcome was prolonged MV, defined as invasive MV lasting more than 14 days. Multivariable logistic regression was performed to identify independent risk factors for prolonged MV. RESULTS: The final analysis included 378 patients. The median duration of MV was 9.7 (IQR 3.0-18.0) days. 221 (58.5 %) patients required MV for more than 7 days and 143 (37.8 %) for more than 14 days. Male gender (aOR 3.01, 95 % CI 1.63-5.58, p < 0.001), age (aOR 1.40, 95 % CI 1.21-1.63, p < 0.001, for each category above 30 years), presence of severe head trauma (aOR 3.77, 95 % CI 2.23-6.38, p < 0.001), and transfusion of >5 blood units on admission (aOR 2.85, 95 % CI 1.62-5.02, p < 0.001) were independently associated with prolonged MV. The number of fractured ribs and the extent of lung contusions were associated with MV for more than 7 days, but not for 14 days. In the subgroup of 134 patients without concomitant head trauma, age (aOR 1.63, 95 % CI 1.18-2.27, p = 0.004, for each category above 30 years), respiratory comorbidities (aOR 9.70, 95 % CI 1.49-63.01, p = 0.017), worse p/f ratio during the first 24 h (aOR 1.55, 95 % CI 1.15-2.09, p = 0.004), and transfusion of >5 blood units on admission (aOR 5.71 95 % CI 1.84-17.68, p = 0.003) were independently associated with MV for more than 14 days. CONCLUSIONS: Several predictors have been identified as independently associated with prolonged MV. Patients who meet these criteria are at high risk for prolonged MV and should be considered for interventions that could potentially shorten MV duration and reduce associated complications. Hemodynamically stable, healthy young patients suffering from severe thoracic trauma but no head injury, including those with extensive lung contusions and rib fractures, have a low risk of prolonged MV.

ABSTRACT

BACKGROUND: The goal of this study was to evaluate any association between blunt chest trauma and occurrence of ST-elevation myocardial infarction and non-ST-elevation myocardial infarction. METHODS: Data from the National Inpatient Sample (NIS) database from 2010-2014, of patients over the age of 40, hospitalized for blunt chest trauma (ICD 959.11), with STEMI or NSTEMI, was used in this study. We performed a chi-squared test to analyze this association. We also performed a multivariant analysis adjusting for race, gender, and age. RESULTS: We found that there is not an increased risk of STEMI/NSTEMI following blunt chest trauma, P > 0.05. We also found no correlation between STEMI or NSTEMI and chest trauma after adjusting for race, gender, and age. For STEMI after adjustments in 2010 (P=0.52), 2011 (P=0.19), 2012 (P=0.60), 2013 (P=0.88), and 2014 (P=0.14). For NSTEMI adjustments in 2010 (P=0.03), 2011 (P=0.06), 2012 (P=0.01), 2013 (P=0.21), and 2014 (P=0.03). CONCLUSION: Both ST-elevation myocardial infarction and non-ST-elevation myocardial infarction were not significantly associated with blunt chest trauma.

ABSTRACT

OBJECTIVE: To analyze the incidence and structure of late complications after blunt chest trauma, feasibility of surgical correction and effectiveness of these interventions. MATERIAL AND METHODS: Treatment outcomes were analyzed in 26 patients with late complications of blunt chest wall trauma. Severe chest deformities were diagnosed in 8 patients, non-union rib fracture - 5, pulmonary hernia - 4, chronic abscesses and pseudocysts of soft tissues of the chest - 3, osteomyelitis of the ribs - 3, chronic recurrent pulmonary bleeding following damage to lung parenchyma by rib fragments - 2, persistent post-traumatic pleuritis - in 1 patient. RESULTS: Among 26 patients, 23 ones underwent surgical correction of complications. Reconstructive procedures were performed in 5 out of 8 patients with post-traumatic chest deformities. In 5 patients with non-union rib fractures, surgery consisted of resection of ribs, excision of capsule and scar tissue, osteosynthesis. Thoracic pulmonary hernia required thoracotomy, viscerolysis, chest wall defect closure by bringing together the ribs and fixing with pulley sutures or ZipFix system. In 2 patients, pulmonary hernia was combined with non-union rib fracture. These patients underwent additional resection of false joints and osteosynthesis. Three patients were diagnosed with chronic abscesses and pseudocysts of soft tissues of the chest. Surgical treatment was carried out according to the principles of staged debridement of chronic purulent foci. Osteomyelitis of ribs in 3 patients required resection within intact tissues. Fixation of ribs by metal structures was not performed in these patients, and we performed only muscle and soft tissue repair. Conservative treatment was carried out in 3 patients with chest deformity. There were no lethal outcomes. CONCLUSION: Pathological syndromes in long-term period after blunt chest trauma require surgical correction. Surgical treatment of patients with late complications of chest trauma should be aimed at chest stabilization, improving respiratory function and preventing secondary and tertiary complications. Osteosynthesis allows not only to eliminate pathological syndromes, but also increase tolerance to physical activity and quality of life.

ABSTRACT

Occult pneumothorax in blunt trauma patients is often diagnosed only after computed tomography because supine chest X-ray (CXR) is preferred as an initial evaluation. However, improperly managed preexisting occult pneumothorax could threaten the vitality of patients. Therefore, this study aimed to evaluate the incidence, characteristics, risk factors, and outcomes of occult pneumothorax in a single trauma center. From 2020 to 2022, patients who were admitted to the level 1 trauma center were retrospectively investigated. Inclusion criteria focused on blunt chest trauma. Variables including demographic factors, image findings, injury-related factors, tube thoracostomy timing, and treatment results were evaluated. Of the 1621 patients, 187 who met the criteria were enrolled in the study: 32 with overt pneumothorax and 81 with occult pneumothorax. Among all of the pneumothorax cases, the proportion of occult pneumothorax was 71.7% (81/113), and its incidence in all admitted trauma victims was 5.0% (81/1621). Subcutaneous emphysema and rib fractures on supine CXR were risk factors for occult pneumothorax. Six patients underwent delayed tube thoracostomy; however, none had serious complications. Given that occult pneumothorax is common in patients with blunt chest trauma, treatment plans should be established that consider the possibility of pneumothorax. However, the prognosis is generally good, and follow-up is an alternative.

ABSTRACT

Background: Traumatic tracheobronchial injury is a rare manifestation after blunt chest injury. The current standard treatment has wide spectrum from conservative treatment to open thoracotomy with repair airway regarding to severity of the disease. However, to the best of our knowledge, no one has reported airway repair in trauma using video-assisted thoracoscopic surgery (VATS) before. Hence, we describe the successful management and repair of a transected right main bronchus using VATS. Case Description: A 43-year-old male patient presented with chest tightness after a traumatic blunt chest injury; a chest computed tomography revealed multiple rib fractures and suspected right main bronchus injury with large pneumomediastinum and subcutaneous emphysema. Although the current standard treatment is to perform open thoracotomy with tracheal repair, we performed VATS repair of right main bronchus in purpose to reduce the stress from tissue trauma and minimally invasive fashion. Emergency surgery was scheduled for injury repair, and the transected right main stem bronchus and mediastinum hematoma were intraoperatively identified. The right main bronchus was repaired using polypropylene 4-0 interrupted sutures under uniportal VATS and covered with pericardial fat pad tissue. After the surgery, the patient had no air leak from chest tube drainage and recovered well. The patient was performed diagnostic bronchoscopy to confirm the patent airway at day 3 then discharged 7 days after surgery and was doing well at a 1-month follow-up. Conclusions: VATS repair is safe and feasible as an alternative approach to conventional thoracotomy approach in the treatment of traumatic tracheobronchial injury.

ABSTRACT

Background: Blunt chest trauma patients with pulmonary contusion are susceptible to pulmonary complications, and severe cases may develop respiratory failure. Some studies have suggested the extent of pulmonary contusion to be the main predictor of pulmonary complications. However, no simple and effective method to assess the severity of pulmonary contusion has been available yet. A reliable prognostic prediction model would facilitate the identification of high-risk patients, so that early intervention can be given to reduce pulmonary complications; however, no suitable model based on such an assumption has been available yet. Methods: In this study, a new method for assessing lung contusion by the product of the three dimensions of the lung window on the computed tomography (CT) image was proposed. We conducted a retrospective study on patients with both thoracic trauma and pulmonary contusion admitted to 8 trauma centers in China from January 2014 to June 2020. Using patients from 2 centers with a large number of patients as the training set and patients from the other 6 centers as the validation set, a prediction model for pulmonary complications was established with Yang's index and rib fractures, etc., being the predictors. The pulmonary complications included pulmonary infection and respiratory failure. Results: This study included 515 patients, among whom 188 developed pulmonary complications, including 92 with respiratory failure. Risk factors contributing to pulmonary complications were identified, and a scoring system and prediction model were constructed. Using the training set, models for adverse outcomes and severe adverse outcomes were developed, and area under the curve (AUC) of 0.852 and 0.788 were achieved in the validation set. In the model performance for predicting pulmonary complications, the positive predictive value of the model is 0.938, the sensitivity of the model is 0.563 and the specificity of the model is 0.958. Conclusions: The generated indicator, called Yang's index, was proven to be an easy-to-use method for the evaluation of pulmonary contusion severity. The prediction model based on Yang's index could facilitate early identification of patients at risk of pulmonary complications, yet the effectiveness of the model remains to be validated and its performance remains to be improved in further studies with larger sample sizes.

ABSTRACT

INTRODUCTION: The diagnosis of cardiac contusion, caused by blunt chest trauma, remains a challenge due to the non-specific symptoms it causes and the lack of ideal tests to diagnose myocardial damage. A cardiac contusion can be life-threatening if not diagnosed and treated promptly. Several diagnostic tests have been used to evaluate the risk of cardiac complications, but the challenge of identifying patients with contusions nevertheless remains. AIM OF THE STUDY: To evaluate the accuracy of diagnostic tests for detecting blunt cardiac injury (BCI) and its complications, in patients with severe chest injuries, who are assessed in an emergency department or by any front-line emergency physician. METHODS: A targeted search strategy was performed using Ovid MEDLINE and Embase databases from 1993 up to October 2022. Data on at least one of the following diagnostic tests: electrocardiogram (ECG), serum creatinine phosphokinase-MB level (CPK-MB), echocardiography (Echo), Cardiac troponin I (cTnI) or Cardiac troponin T (cTnT). Diagnostic tests for cardiac contusion were evaluated for their accuracy in meta-analysis. Heterogeneity was assessed using the I2 and the QUADAS-2 tool was used to assess bias of the studies. RESULTS: This systematic review yielded 51 studies (n = 5,359). The weighted mean incidence of myocardial injuries after sustaining a blunt force trauma stood at 18.3% of cases. Overall weighted mean mortality among patients with blunt cardiac injury was 7.6% (1.4-36.4%). Initial ECG, cTnI, cTnT and transthoracic echocardiography TTE all showed high specificity (> 80%), but lower sensitivity (< 70%). TEE had a specificity of 72.1% (range 35.8-98.2%) and sensitivity of 86.7% (range 40-99.2%) in diagnosing cardiac contusion. CK-MB had the lowest diagnostic odds ratio of 3.598 (95% CI: 1.832-7.068). Normal ECG accompanied by normal cTnI showed a high sensitivity of 85% in ruling out cardiac injuries. CONCLUSION: Emergency physicians face great challenges in diagnosing cardiac injuries in patients following blunt trauma. In the majority of cases, joint use of ECG and cTnI was a pragmatic and cost-effective approach to rule out cardiac injuries. In addition, TEE may be highly accurate in identifying cardiac injuries in suspected cases.

ABSTRACT

Introduction: Chest imaging plays a prominent role in the assessment of patients with blunt trauma. Selection of the right approach at the right time is fundamental in the management of patients with blunt chest trauma.[1] A reliable, economic, bedside, and rapidly accomplished screening test can be pivotal. [2]. Objective: The aim of this study was to compare the accuracy of extended- focused assessment with sonography for trauma (E-FAST) to that of the National Emergency X-Radiography Utilisation Study (NEXUS) chest algorithm in detecting blunt chest injuries. Methods: This descriptive cross-sectional study included 50 polytrauma patients with blunt chest trauma from the emergency centre of Suez Canal University Hospital. E-FAST and computed tomography (CT) were conducted, followed by reporting of NEXUS criteria for all patients. Blinding of the E-FAST performer and CT reporter were confirmed. The results of both the NEXUS algorithm and E-FAST were compared with CT chest results. Results: The NEXUS algorithm had 100% sensitivity and 15.3% specificity, and E-FAST had 70% sensitivity and 96.7% specificity, in the detection of pneumothorax.In the detection of hemothorax, the sensitivity and specificity of the NEXUS algorithm were 90% and 7.5%, respectively, whereas E-FAST had a lower sensitivity of 80% and a higher specificity of 97.5%. Conclusion: E-FAST is highly specific for the detection of hemothorax, pneumothorax, and chest injuries compared with the NEXUS chest algorithm, which demonstrated the lowest specificity. However, the NEXUS chest algorithm showed a higher sensitivity than E-FAST and hence can be used effectively to rule out thoracic injury.

ABSTRACT

OBJECTIVE: Anterior flail chest frequency represents a significant case of ventilator insufficiency. Surgical stabilization of acute phase of trauma is considered to effectively shorten the period of ventilation compared to conservative treatment using mechanical ventilation. We have applied minimally invasive surgery to stabilize the injured chest wall. METHODS: Surgical stabilization of predominantly anterior flail chest segments was performed using one or two bars as per the Nuss procedure, during the acute phase of chest trauma. Data from all patients were examined. RESULTS: Ten patients received surgical stabilization using the Nuss method between 1999 and 2021. All patients had already been mechanically ventilated prior to surgery. The mean period from trauma to surgery was 4.2 days (range, 1-8 days). The number of bars used was one for 7 patients, and two for 3 patients. The mean operation time was 60 min (range, 25-107 min). All patients were extubated from artificial respiration without surgical complications or mortality. Mean total ventilation period was 6.5 days (range, 2-15 days). All bars were removed in a subsequent surgery. No collapses or fracture recurrences were observed. CONCLUSION: This method is simple and effective for fixed anterior dominant frail segment.

ABSTRACT

Graves' disease can manifest with numerous cardiovascular complications, although very few cases result in cardiomyopathy. Our patient presented following a motor vehicle accident where she suffered blunt chest trauma. Her initial presentation was concerning for acute heart failure due to blunt cardiac injury, with diffuse pulmonary edema, hemodynamic instability, and an acutely reduced ejection fraction with global hypokinesis on transthoracic echocardiography. On further evaluation with thyroid function testing and autoimmune studies, she was found to have uncontrolled Graves' disease. She was subsequently started on methimazole for her Graves' cardiomyopathy. Following discharge, an outpatient cardiac MRI revealed no late gadolinium enhancement and complete recovery of her ejection fraction to normal values. This case serves to highlight the importance of a complete evaluation of cardiomyopathy and highlights an interesting case of a patient with blunt chest injury with a background of undetected Graves' cardiomyopathy.

ABSTRACT

As the clinical manifestations of traumatic tricuspid valve regurgitation vary according to the extent of tricuspid valve injury, this condition can often go unnoticed and be incidentally discovered. Here, we report the case of a 40-year-old man with patent foramen ovale, in which severe tricuspid regurgitation due to tricuspid valve prolapse was incidentally discovered following blunt chest trauma. Further examination revealed that the prolapse had also caused active right ventricular mural infective endocarditis. The patient had no relevant past medical history of chronic debilitating disease or immunosuppression. After evaluation by the cardiology team, emergent surgical tricuspid valvular repair was successfully performed. Learning objective: Tricuspid valve prolapses resulting from chest trauma may occasionally lead to severe tricuspid regurgitation. Furthermore, this may cause active right ventricular infective endocarditis. In the present case, Staphylococcus aureus was detected in blood cultures, which is usually rapidly progressive and often leads to devastating consequences. Early surgical approach should be considered in cases of infection in the left atrium via patent foramen ovale.
