Right ventricle pierced by a traditional sharp hair straightener: a case report.

The case presents a traumatic ventricular perforation of a girl, accidentally felt on a sharp instrument. The uniqueness of the case presented is due to the very high infrequency of injuries with this type of sharp object. The 7-year-old girl was transported to the hospital after accidentally falling on a sharp instrument. The child had no signs of heart failure. On opening the chest, it was found that the metal object was lodged in the right ventricle. Quickly proceeded to remove the object and suture the entry hole. After a short hospitalization, the child was discharged completely cured.

Needle Decompression Complicated by Cardiac Injury in a Prehospital Environment.

Needle decompression is a mainstay intervention for tension pneumothorax in trauma medicine. It is used in combat and prehospital medicine when definitive measures are often not available or ideal. It can temporarily relieve increased intrathoracic pressure and treat a collapsed lung or great vessel obstruction. However, when done incorrectly, it can result in underlying visceral organ and vessel trauma. This is a case of an adult male who presented to the emergency department after sustaining multiple stab wounds during an altercation. On arrival, the patient had a 14-gauge angiocatheter inserted at the 4th intercostal space (ICS), left of the parasternal line traversing the right ventricle and interventricular septum and terminating in the left ventricle. The case emphasizes the importance of understanding the landmarks of performing needle decompression in increasing the procedure's efficacy and reducing iatrogenic complications.

Two-Stage Liver Transplantation and Tricuspid Valve Replacement After Blunt Trauma in a Pediatric Patient.

In cases of uncontrollable hepatic hemorrhage or acute hepatic failure after trauma, liver transplantation can be a lifesaving procedure. Traumatic tricuspid valve injuries are rare, and symptoms can range from indolent to acute right heart failure. When concomitant, traumatic liver transplant and tricuspid injuries have significant physiologic interplay and management implications. We present a 14-year-old male injured in an all-terrain vehicle accident, who sustained a devastating disruption of the common bile duct and celiac artery injury, leading to acute hepatic failure, necessitating a two-stage liver transplantation. He was subsequently found to have a severe traumatic tricuspid injury, which required tricuspid valve replacement. At 4 years post-injury, he is without major complications. This is the first case presentation of the cooccurrence of these complex pathologies. Importantly, we demonstrate the complex decision-making surrounding traumatic liver transplantation and timing of subsequent tricuspid valve repair, weighing the complex interplay of these 2 pathologies.

Management of contained penetrating cardiac injury in a patient with prior cardiac surgery.

Penetrating cardiac injuries usually require emergent surgical intervention. Our patient presented to the trauma centre with multiple stab wounds to the neck, chest, epigastric region and abdomen. She arrived haemodynamically stable, and her initial Focused Assessment with Sonography for Trauma exam was negative. Her chest X-ray did not show any evident pneumothorax or haemothorax. Due to her injury pattern, she was taken to the operating room for exploratory laparotomy and neck exploration. Postoperatively, she was taken for CT and found to have a contained cardiac rupture. The injury was contained within previous scar tissue from her prior cardiac surgery. Further evaluation revealed that the injury included a penetrating stab wound to the right ventricle and a traumatic ventricular septal defect (VSD). She subsequently underwent a redo sternotomy with the repair of the penetrating stab wound and the VSD. Cardiology, intensive care, trauma surgery and cardiothoracic surgery coordinated her care from diagnosis, management and recovery. This case highlights the challenges in the management of cardiac injuries and the benefits of a multidisciplinary approach to care for complex cardiac injuries.

No cupid, just an arrow: a penetrating injury into the interventricular septum.

BACKGROUND: Penetrating cardiac injuries are rare but often fatal, with 16-55% mortality. We report a patient who suffered a non-fatal occupational cardiac injury. CASE PRESENTATION: A 47-year-old man was operating an ironworker machine. A thin 3-cm metal fragment catapulted from the machine piercing the chest wall and the right ventricular outflow tract (RVOT), burrowing into the interventricular septum (IVS). The patient remained hemodynamically stable and walked to the nearest hospital. ECG-gated computed tomography revealed the exact location of the fragment within the IVS, allowing for detailed preoperative planning. The fragment was removed through a sternotomy and an incision through the RVOT. The postoperative course was uneventful. CONCLUSIONS: This case underscores the value of detailed preoperative imaging and the wide spectrum of clinical scenarios of penetrating cardiac injuries.

Right ventricular lead perforation with iatrogenic injury to an intercostal artery causing haemothorax after pacemaker implant.

A woman in her 80s experienced a life-threatening complication of pacemaker implant consisting of subacute right ventricular lead perforation causing iatrogenic injury to an intercostal artery, resulting in a large haemothorax. A CT scan confirmed active bleeding from the fourth intercostal artery. The patient underwent cardiothoracic surgery via a median sternotomy approach, during which the source of the bleeding was sealed, a new epicardial lead was positioned, and the original lead was extracted. This case emphasises the potentially severe consequences of pacemaker lead perforation and secondary injury to adjacent structures. It underscores the importance of early recognition and timely intervention, preferably in a tertiary specialist unit equipped for cardiothoracic surgery and confirms the value of pacemaker interrogation and CT scans for diagnosis.

Rescue Sternotomy in a 540†g Neonate for Right Atrial Perforation During Percutaneous Ductal Device Occlusion.

Percutaneous ductal device closure in neonates is gaining popularity. Cardiac perforation is a rare but catastrophic complication that can occur during this procedure. Surgical options to salvage this situation are limited in extremely low-weight babies. In this report, we describe one such case managed successfully and offer some suggestions to achieve a successful outcome.

[Surgical Treatment of the Perforation of the Right Ventricle and Diaphragm by a Permanent Pacing Lead:Report of a Case].

An 97-year-old woman was diagnosed with complete atrioventricular block and underwent pacemaker implantation( PMI). Three days after the PMI, computed tomography revealed cardiac perforation and migration of the lead to the abdominal cavity. Surgical procedure through median sternotomy was performed, and the penetrated lead was removed. The holes of the right ventricle and diaphragm were repaired. Abdominal organ was not injured. She was discharged 14 days after the surgical procedure.

[Surgical Removal of a Transvenous Pacemaker Lead with the Right Atrial Perforation:Report of a Case].

Cardiac perforation by a transvenous pacemaker lead is an uncommon, but serious complication. Management strategies in pacemaker lead cardiac perforation depend on the symptoms, the presence of pericardial effusion, hemodynamic status, and injured neighboring organs. A 70-year-old man was admitted due to suspicious right atrial perforation with pneumothorax secondary to a transvenous pacemaker lead. Right atrial perforation was confirmed on computed tomography (CT). A large laryngopharyngeal hemangioma compressing the trachea was also observed. Although he was hemodynamically stable, we chose a surgical removal of a transvenous pacemaker lead considering his large laryngopharyngeal hemangioma. A tracheotomy followed by lower hemisternotomy were performed. A perforated pacemaker lead was observed on the right atrium. The lead was pulled out, and a hole in the right atrium was fixed. His postoperative course was uneventful.

Linear epicardial cryoablation effects in a porcine model: Lesion characteristics and vascular risk.

INTRODUCTION: Cryoablation in open-chest surgical interventions for ventricular arrhythmias has been reported with reasonable procedural outcomes. However, the characteristics of cryoablation lesions on the ventricular myocardium are not well defined. The purpose of the present study was to determine the tissue and vascular effects of a linear epicardial cryoablation probe in a porcine animal model. METHODS: Five adult Yorkshire swine underwent median sternotomy and application of linear cryoablation lesions using a malleable aluminum linear cryoablation probe of varying duration (2, 3, 4, and 5 min), including one lesion placed intentionally over the left anterior descending coronary (LAD) artery. Histological analysis was performed. RESULTS: Maximum lesion depth was approximately 1.0 cm with 3 min freezes, with no significant increase in depth achieved with longer lesions. No transmural lesions were achieved. No large vessel epicardial coronary artery injuries were seen to the LAD; however, surprisingly, remote isolated interventricular septal injury was seen in all animals, suggestive of possible compromise of smaller coronary arterial vessels. CONCLUSION: Single application freezes with an aluminum linear cryoablation probe can create homogeneous ablative lesions over the ventricular myocardium with a maximum depth of approximately 1.0 cm. No large vessel injury occurred with direct lesion application of the LAD; however, small coronary vessels may be at risk.

Management of Penetrating Cardiac Injuries With Pericardial Window and Drainage in Select Patients.

BACKGROUND: Management of penetrating chest injuries with a positive pericardial window (PW) are presumed cardiac injuries and traditionally result in sternotomy. However, there is some evidence in the literature that select patients can be managed with PW, lavage, and drainage (PWLD). METHODS: All patients with penetrating chest trauma who underwent PW and/or sternotomy over a 5-year period were identified. Patients were stratified by operative intervention [PW + sternotomy vs PWLD] and compared. Multivariable logistic regression (MLR) analysis was performed to determine independent predictors of therapeutic sternotomy. RESULTS: Of the 146 patients who underwent PW and/or sternotomy included in the study, 126 patients underwent PW, 39 underwent sternotomy, and 10 underwent PWLD. There was no difference in demographics, LOS, ICU LOS, vent days, or mortality in patients who underwent PW + sternotomy, compared to patients who underwent PWLD. In the PWLD group, one patient returned to the OR for recurrent pericardial effusion and no patients required sternotomy. Multivariable logistic regression identified ISS as an independent predictor of therapeutic sternotomy (OR 1.160; 95% CI 1.006-1.338, P = .0616). Interestingly, positive FAST, significant CT findings, and trajectory were not predictors of therapeutic sternotomy. There were 7 patients with a left hemothorax and negative FAST found to have a positive PW and cardiac injury mandating sternotomy and repair. CONCLUSION: Penetrating cardiac injury can be managed with PWLD in select patients. Positive FAST, significant findings on CT, and trajectory do not mandate sternotomy. A negative FAST in the setting of a hemothorax does not rule out a cardiac injury.

Post-cardiac injury syndrome after surgical repair of atrial septal defect: Reporting a rare occurrence.

A 16-year-old male with past medical history of congenital atrial septal defect surgical repair, presented with recurrent pericarditis secondary to post-cardiotomy injury syndrome (PCIS), After failing medical therapy, he ultimately underwent pericardiectomy for symptom resolution, PCIS is underdiagnosed in children and should be considered in patients with recurrent chest, pain.

Delayed Right Ventricular Pacemaker Lead Perforation 9 Years After Implantation.

BACKGROUND Cardiac perforation is a rare complication of cardiac implantable electronic devices, with a reported incidence ranging from 0.1% to 5.2%. Delayed perforation, defined as perforation occurring more than 1 month after implantation, is more uncommon. In this report, we present a case of cardiac perforation involving the right ventricle wall that occurred 9 years after pacemaker implantation. CASE REPORT A 79-year-old woman presented with symptoms of dyspnea and was subsequently admitted to a hospital. She had undergone pacemaker implantation for a complete atrioventricular block 9 years prior to the presentation. The patient had right ventricular failure to capture and a resultant complete atrioventricular block. Computed tomography imaging revealed that the right ventricular lead had clearly protruded outside the heart; however, no pericardial effusion was observed. When the patient underwent open surgical repair, the ventricular tined lead was noted to be traversing the right ventricular apex. Device interrogation revealed a sudden increase followed by a gradual decrease in the right ventricular pacing threshold over the course of 2 months, indicating that the lead had slowly traversed the right ventricular muscle before ultimately rupturing through it. CONCLUSIONS This study described the case of a delayed right ventricular pacemaker lead perforation that occurred 9 years after implantation, which was managed via open surgical repair.
