Systematic Review of Penetrating Cardiac Injury by a Firearm: Forensic Implications

Penetrating Cardiac Injury: A 20-Year Retrospective Analysis at a High-Complexity University Center

INTRODUCTION

Penetrating cardiac injury, though infrequent, is associated with substantial mortality. In 2005, our research team conducted a comprehensive retrospective analysis of penetrating cardiac injuries managed at our facility from 1990 to 2003. Now, two decades later, we conducted the present study on penetrating cardiac injuries attended in our hospital over the last 20 years.

METHODS

This is a retrospective analysis of medical records and trauma database data, with a focus on survivors of penetrating cardiac trauma, excluding those deceased upon arrival.

RESULTS

Out of 1,093 cases, 25 had penetrating cardiac injuries with an overall mortality rate of 36%. Hemorrhage was the leading cause of death, and survival was correlated with higher systolic blood pressure upon admission and the level of consciousness.

CONCLUSION

The study highlights the need for rapid intervention and emphasizes the importance of managing bleeding and supporting hemodynamics. It also points to areas for improvement in emergency care and the benefits of interdisciplinary collaboration.

Surviving the Storm: Insights Into the Pericardial Injuries and Roller Coaster of Multisystem Trauma in Bomb-Blast Victims

Pericardial injuries due to penetrating trauma such as bomb-blast shrapnel are rare but are associated with significant mortality. Timely diagnosis and a multidisciplinary approach are essential for effective management. This case series, comprising two cases, emphasizes the need for rapid, appropriate imaging and multidisciplinary care in the management of all associated injuries in these complex polytrauma patients. It also underscores the need for a high index of suspicion despite negative clinical features of pericardial injuries for timely performing CT scans and adaptive treatment strategies, including life-saving surgical intervention.

Diagnostic Challenges in Uncommon Firearm Injury Cases: A Multidisciplinary Approach

Background: Firearm wounds tend to have a precise pattern. Despite this, real-world case presentations can present uncertain elements, sometimes deviating from what is considered standard, and present uncommon features that are difficult for forensic pathologists and ballistic experts to explain. Methods: A retrospective analysis of autopsy reports from the Institute of Legal Medicine, University of Catania, covering 2019-2023, included 348 judicial inspections and 378 autopsies performed as part of the institute's overall activities. Among these, seventeen cases of firearm deaths were identified, with three atypical cases selected for detailed analysis. An interdisciplinary approach involving forensic pathology, radiology, and ballistics was used. Results: The selected cases included: (1) A 56-year-old female with a thoracic gunshot wound involving three 7.65 caliber bullets, displaying complex trajectories and retained bullets; (2) A 48-year-old male with two cranial gunshot injuries, where initial evaluation suggested homicide staged as a suicide, later confirmed to be a single self-inflicted shot; and (3) A 51-year-old male was found in a car with two gunshot wounds to the head, involving complex forensic evaluation to distinguish between entrance and exit wounds and determine trajectory. The findings showed significant deviations from standard patterns, underscoring the critical role of radiological imaging and ballistic analysis in understanding wound morphology and projectile trajectories. Conclusions: This case series highlights the necessity for standardized yet adaptable protocols and cooperation among forensic specialists. A flexible approach allows forensic investigations to be tailored to the specific circumstances of each case, ensuring that essential examinations are conducted while unnecessary procedures are avoided. Comprehensive data collection from autopsies, gross organ examinations, and, when needed, radiological and histological analysis is essential to accurately diagnose injuries, trace bullet trajectories, retrieve retained projectiles, and determine the fatal wound, particularly in complex cases or those involving multiple shooters.

Management of cardiac trauma and penetrating cardiac injuries with severe hemorrhagic shock: a 5-year experience

PURPOSE

The diagnosis and management of cardiac trauma and penetrating cardiac injuries pose significant challenges in emergency settings due to the rapid onset of life-threatening complications. This paper presents a narrative review to better describe the etiology, presentation, and management of penetrating cardiac trauma, offering insights and experiences related to performing emergency surgery for such cases.

METHODS

We compiled cases of traumatic cardiac rupture and penetrating cardiac injuries accompanied by severe hemorrhagic shock that necessitated emergency surgery. Data were collected regarding the type of injury, causative agents, specific clinical features observed during emergency admission, intraoperative parameters, and treatment outcomes.

RESULTS

Twenty-one patients (16 men, 5 women) with cardiac rupture or penetrating cardiac injuries were recorded. All patients presented in severe shock, and six cases (28.6%) experienced cardiac arrest upon arrival in the operating room. Cardiac rupture due to blunt chest trauma occurred in two cases (9.5%), and one case (4.8%) involved right atrial perforation due to complex open chest trauma. Penetrating injuries accounted for cardiac perforation in 18 cases (85.7%). Associated injuries were present in 11 cases (52.4%). The intraoperative mortality rate was 9.5%, and there was one postoperative death on the 11th day due to multiorgan failure.

CONCLUSIONS

Cardiac trauma and penetrating injuries are usually fatal unless promptly diagnosed and surgically treated. The timing and rapidity of emergency surgery-often foregoing ancillary tests and administrative procedures-are critical for patient survival. Emergency sternotomy, swift control of bleeding, and aggressive resuscitation are essential operative measures in saving lives. Factors that influence prognosis include the extent of blood loss, duration of cardiac arrest, acid-base imbalances, coagulopathy, multiorgan failure, and postoperative infections.

Unusual pattern of firearm injury to trunk and limbs: Two case reports and review

This article presents two cases of fatal injuries from rifled weapons with unconventional shapes of inlets and exits mismatched with the distance of firing. According to forensic literature, in long-distance ranges, we expected to see rounded entry wounds smaller than bullet size, circular in shape without associates with limited damage in the tissues. In the first case, there were large wounds which did not match a distance of more than 2 m, while in the second case, the distance was more than 30 m with large wounds 21 × 10 cm and massive damage to bones and lungs. In the first case, a 25-year-old male, he had multiple wounds in the front of the chest, the first one over the sternum end measuring 9 × 7 cm rounded in shape with fracture of the ribs, sternum and lung laceration. The second wound was 3 × 5 cm in the lateral aspect - mid axillary line and it was superficial due to tangential passage of the missile. In the left thigh, two inlets, each approximately 5 × 7 cm, were seen, the first one over the left iliac bone rounded and the second inlet was in the midshaft of the femur. The exit was below the left gluteus, rounded in shape 5 × 7 cm. The second case a 19-year-old male, he showed single oval wound in the middle third of the back, and it measured 21 × 10 cm. The missile passed tangentially and led to broken ribs and the vertebral column with a lung laceration.

Sudden death associated with delayed cardiac rupture: case report and literature review

Cardiac injury plays a critical role in the process of thoracic trauma-related fatal outcomes. Historically, most patients who suffer a cardiac rupture typically die at the scene of occurrence or in the hospital, despite prompt medical intervention. Delayed cardiac rupture, although rare, may occur days after the initial injury and cause sudden unexpected death. Herein, we present the clinical details of a young man who suffered a chest stab injury and recovered well initially, but died days later due to delayed cardiac rupture. The forensic autopsy confirmed delayed cardiac rupture as the cause of death. We also reviewed previous similar reports to provide suggestions in such rare cases in clinical and forensic practice.

Renal injuries in conflict zones: a 6-year study of traumatic cases in Afghanistan

PURPOSE

During hostilities, gunshot wounds are the most common cause of penetrating injuries. In 8-10% of abdominal injuries kidneys are involved. The treatment method include surgical or conservative treatment (fluids + blood components).

METHODS

Of 1266 combat trauma cases treated during 6 to 14 rotation of the Polish Military Contingent in Afghanistan, we extracted a subgroup of 44 kidney injuries. Corelation of trauma mechanism, PATI score, treatment methods, and outcomes was evaluated.

RESULTS

Out of the 41 renal injuries, 20 considered left, 18 right, and 3 both kidneys. There were no statistical significancy in injury lateralization (p = 0.669), and no differences regarding side of a trauma and quantity of blood component used for the treatment (p = 0.246). Nephrectomy was performed on 17 patients (13 left vs. 4 right). A significant correlation between PATI score and the need for a nephrectomy (p = 0.027) was confirmed. Penetrating trauma recquired higher number of blood components comparing to blunt trauma (p < 0.001). The renal salvage rate was in study group was 61.36%. The overall survival (OS) rate was 90.25% - 4 patients died due to trauma.

CONCLUSIONS

The damage side does not result in a statistically significant increase in the need for blood transfusions or differences in the PATI score. The mechanism of trauma does, however, affect the number of blood components required for treatment, particularly in cases of penetrating trauma. With the introduction of proper treatment, the overall survival rate exceeds 90%, even when opting for conservative treatment.
