Penetrating cardiac injury after percutaneous breast core-needle biopsy, unusual life-threatening complication: a case report.

BACKGROUND: Complications after percutaneous breast biopsy are infrequent but may include hematoma, pseudoaneurysm formation, persistent pain, infection, delayed wound healing, vasovagal reaction, hemothorax, pneumothorax, and neoplastic seeding. The risk factors include tumor factors (size, location, vascularity), procedure-related factors (needle diameter, number of biopsies), and interventionist experience. There has been no previous report of a fatal complication resulting from percutaneous breast biopsy. CASE PRESENTATION: We report a 54-year-old Asian woman with a 3 cm BI-RADS® 4B left breast mass in the lower-inner quadrant who was biopsied by a 16 G needle under ultrasound guidance at a province hospital. She experienced dizziness and near-syncope afterward. The initial evaluation showed evidence of cardiac tamponade with hemodynamic instability. She underwent urgent subxiphoid pericardial window and was transferred to our facility. We brought her directly to the operating room to perform an explorative median sternotomy and found a 0.2 cm hole in the right ventricle. The injured site was successfully repaired without cardiopulmonary bypass. Postoperative echocardiography demonstrated mild right ventricular dysfunction without evidence of septal or valvular injury. She survived with no significant complications. DISCUSSION: This case might be the first report of a life-threatening complication related to percutaneous breast core-needle biopsy. The rapid pericardial release is key to the survival of cardiac tamponade. The patient subsequently required cardiac repair and monitoring to avoid long-term complications. In this report, we suggested a safe biopsy method, complications recognition, and appropriate management of penetrating cardiac injury. CONCLUSION: Penetrating cardiac injury resulting from percutaneous breast biopsy is extremely rare but can occur. A biopsy must be done cautiously, and worst-case management should promptly be considered.

Cardiac Perforation Caused By Pectus Excavatum Metal Bar Stabilizer: A Case Report.

This paper reports the case of a female patient who underwent minimally invasive repair of pectus excavatum (MIRPE) in another service that evolved with bar rotation and cardiac perforation caused by the left stabilizer. The unique and frightening aspect of the case is that despite having the stabilizer inside the ventricle, the patient was oligosymptomatic: occasional chest pain and respiratory discomfort. Preoperative imaging showed rotation of the bar with stabilizers within the thoracic cavity. During surgery, intense ossification was observed around the prosthesis and it was noted that the left stabilizer had perforated the patient's left ventricle. Cardiac repair required a Clamshell incision and cardiopulmonary bypass. This case reinforces the validity of late radiological follow-up after MIRPE in an attempt to avoid this type of event, and the need to reevaluate the use of stabilizers perpendicular to the bar since they are not safe to prevent rotation of these implants.

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.

[Air Embolism of the Left Ventricle due to Pulmonary Stab Wound].

A man in his 50s was stabbed deeply in the back with a knife and brought to the emergency room. He was found to have a significant left hemopneumothorax. He was planned to undergo hemostatic surgery under general anesthesia. However, shortly after the change in a right lateral decubitus position, he experienced ventricular fibrillation. Hemostasis of the intercostal artery injury, the source of bleeding, and suture of the injured visceral pleura were performed under extracorporeal membrance oxgenation( ECMO). Although sinus rhythm was resumed, when positive pressure ventilation was applied to the left lung for an air leak test, ST elevation on the electrocardiogram and loss of arterial pressure occurred. A transesophageal echo revealed air accumulation in the left ventricle. It was determined that air had entered the damaged pulmonary vein from the injured bronchi due to the stab wound, leading to left ventricular puncture decompression and lower left lower lobectomy. Subsequently, his circulatory status stabilized, and ECMO was weaned off. He recovered without postoperative neurological deficits postoperatively. The mortality rate for chest trauma with systemic air embolism is very high. In cases of deep lung stab wounds, there is a possibility of systemic air embolism, so treatment should consider control of airway and vascular disruption during surgery.

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.

Introdução: A avaliação dos índices de trabalho miocárdico global em condições basais pode ser útil para a estratificação clínica de pacientes com suspeita de obstrução coronariana. Objetivo: Correlacionar o valor do índice de trabalho miocárdico global e a presença de lesões obstrutivas coronarianas significativas. Método: Estudo transversal, com pacientes encaminhados para cinecoronarioangiografia eletiva. Foi realizado ecocardiograma com obtenção das medidas para cálculo do valor do trabalho miocárdico, sendo avaliada a presença de lesões obstrutivas coronarianas significativas à cinecoronarioangiografia. Resultados: A amostra foi composta de 30 pacientes, com a idade média de 64,2±12,8 anos, sendo a maioria do sexo masculino (63,3%), dos quais 68,4% apresentaram lesões obstrutivas coronarianas significativas. O índice de trabalho miocárdico global foi de 1.876mmHg%±253,8 no grupo com lesões obstrutivas coronarianas significativas e de 2.054,2mmHg%±417,3 naqueles sem lesões significativas (p=0,089). O trabalho miocárdio construtivo global nos pacientes sem lesões obstrutivas coronarianas significativas foi maior (2.329,3mmHg%±462,9) do que naqueles com lesões obstrutivas coronarianas significativas (2.109,5mmHg%±332,3; p=0,064). O trabalho miocárdio desperdiçado global foi maior nos pacientes com lesões obstrutivas coronarianas significativas (103,7mmHg%±47,1 versus 68,3mmHg%±33,8; p=0,038). O ponto de corte de 115mmHg% foi aquele com a melhor área sob a curva (0,625), com sensibilidade de 83,3%. Conclusão: O aumento do trabalho miocárdio desperdiçado global se correlacionou com a presença de lesões obstrutivas coronarianas significativas em nossa amostra.(AU)

Introduction: The assessment of global myocardial work indices under baseline conditions may be useful for the clinical stratification of patients with suspected coronary obstruction. Objective: To correlate the value of global myocardial work indices and the presence of significant obstructive coronary lesions. Method: Cross-sectional study, with patients referred for elective coronary angiography. An echocardiogram was performed to obtain measurements to calculate the value of myocardial work and evaluated the presence or presence of significant obstructive coronary lesions at coronary angiography. Results: The sample consisted of 30 patients, with a mean age of 64.2±12.8 years, the majority being male (63.3%), of which 68.4% had significant obstructive coronary lesions. The global myocardial work indices was 1,876mmHg%±253.8 in the group with significant obstructive coronary lesions and 2,054.2mmHg%±417.3 in those without significant lesions (p=0.089). Global constructive myocardial work in patients without significant obstructive coronary lesions was higher (2,329.3mmHg%±462.9) than in those with significant obstructive coronary lesions (2,109.5mmHg%±332.3; p=0.064). Global wasted myocardial work was higher in patients with significant obstructive coronary lesions (103.7mmHg%±47.1 versus 68.3mmHg%±33.8; p=0.038). The cutoff point of 115 mmHg% was the one with the best area under the curve (0.625), with a sensitivity of 83.3%. Conclusion: The increase in global wasted myocardial work correlated with the presence of significant obstructive coronary lesions in our sample. (AU)

The Self-Inflicted Multiple Organs Injury with Nail Gun.

We report the case of a patient with injuries to multiple organs as a result of attempted suicide with a nail gun. The patient shot 12 nails into his chest, causing damage to multiple organs, including the heart, lungs, and stomach. With timely emergency surgery, we successfully removed all the nails, and the patient was discharged from the hospital two weeks after surgery.

[Penetrating Right Ventricular Injury by Suicide Attempt:Report of a Case].

Penetrating heart injury is rare in Japan. A 35-year-old man stabbed himself with a fruit knife that was about 10 cm in length on the left precordium in an attempt to commit suicide and was transferred to our hospital. His vital signs were stable, and the knife remained stabbed in the left precordium. Cardiac injury and cardiac tamponade were suspected on computed tomography, and emergency surgery was performed. A large amount of red hematoma was found in the mediastinum and the pericardial space after median sternotomy. The knife had created a fissure of about 15 mm in the free wall of the right ventricle, and the injury was repairable. The knife passed through the sixth costal cartilage and the left internal thoracic artery, and hemostasis was easy. The patient's postoperative course was uneventful, but due to the suicide attempt and adjustment disorder, the patient was transferred to a psychiatric hospital on postoperative day 10.

Effects of platelet rich plasma on experimentally induced diabetic heart injury.

Diabetic heart is one of the common complications of diabetes mellitus. Platelet-rich plasma (PRP) is an autologous product rich in growth factors that can enhance tissue regeneration. This work was conducted to study the PRP ability to improve diabetes-inducing cardiac changes. Also, it sheds more light on the possible mechanisms through which PRP induces its effects. Rats were divided into; control, PRP, diabetic, and PRP-diabetic groups. Cardiac specimens were obtained and processed for biochemical, histological, and immunohistochemical study. The diabetic group exhibited a significant increase in cardiac oxidative stress, inflammation, and cardiac injury markers if compared with the control group. Additionally, the cardiac tissue showed variable morphological changes in the form of focal distortion and loss of cardiac myocytes. Distorted mitochondria and heterochromatic nuclei were observed in the cardiac muscle fibers. The mean number of charcoal-stained macrophages, and mean area fraction for collagen fibers, mean number of PCNA-immune positive cardiac muscle were significantly decrease in PRP- diabetic group. Collectively, the results showed that PRP treatment ameliorated most of all these previous changes. CONCLUSION: PRP ameliorated the diabetic cardiac injury via inhibition of oxidative stress and inflammation. It was confirmed by biochemical, histological, and immunohistochemical study. It could be concluded that PRP could be used as a potential therapy for diabetic heart.

Removal of Unusual Foreign Metal Object (Nail) from the Right Ventricle of Human Heart: A Case Report.

Migration of foreign bodies (FB) with the blood flow to the heart is a rare, but very alarming condition as it may lead to life-threatening complications and death. Objects that are larger than 5 mm in diameter and/or irregular in shape are recommended for removal from extra- and intracardiac areas to prevent incurable embolization. Surgical extraction of intracardiac objects is a serious surgical challenge associated with difficulties to operate, during the continuous movement of the heart, and identify the exact FB location. Early diagnosis and timely removal of FBs are crucial treatment factors for this rare case resolution. We report a case of accidental migration of a metal FB object (nail) about 1.0*0.3 cm from the right neck area jugular vein to the right ventricle apex in the heart. The FB localization was accurately detected using Bi-plane transesophageal echocardiography (TEE) with a special comet-tail artifact. TEE provided valuable information before surgery, and the nail was successfully removed through open-heart surgical procedures and cardiopulmonary bypass (CPB). Postoperative tests indicated no complications.

Left ventricular perforation from a dislodged needle migrating via a pulmonary artery branch in an intravenous drug user.

Embolised needles causing injury to the right heart and cardiac tamponade has been reported before in intravenous drug users, but to our knowledge, this is the first reported case of a needle migrating via the pulmonary arterial system to cause perforation of the left ventricle. Appropriate utilisation of imaging modalities such as plain X-ray and point-of-care focused cardiac ultrasound can be vital and life-saving in the emergency setting, and the value of gated multidetector CT as a powerful tool for imaging moving structures is highlighted.

Intraventricular entrapment of a Sapien-3 balloon in transapical TAVR: A near missed catastrophe.

Balloon rupture is an uncommon complication during balloon-expandable transcatheter aortic valve replacement (TAVR). We describe a balloon rupture and tearing with intraventricular entrapment complicating transapical-TAVR, as well as our bailout retrieval of the failed device.

Sandwich Technique to Manage Right Ventricular Perforation During Beating Heart Coronary Artery Bypass Grafting.

Identification of an intramyocardial left anterior descending artery remains challenging and many techniques have been proposed for its identification. The exposure technique depends on the surgeon's familiarity and experience with it, and inadvertent right ventricular perforation during exposure on off-pump surgery results in bleeding, which requires urgent cardiopulmonary support and repair. Inadequate repair may result in continued bleeding, closure of the left anterior descending artery, and myocardial infarction. We describe a sandwich technique using the native left anterior descending artery and the bypass graft to repair right ventricular perforation, avoiding closure of this main artery and preserving graft patency.

Contained rupture of right ventricular outflow tract after Rastelli-type operation.

This report describes a 3-year-old infant with post-operative mediastinitis complicated by a contained rupture of the right ventricle. A contained rupture is recognised as the huge pulsating prominence of the anterior chest wall. CT confirmed blood communication between the right ventricular outflow tract and the cavity surrounded by the pectoral major musculocutaneous flap. This is a significant case in which severe adhesion between the right ventricle and the musculocutaneous flap could maintain her stable haemodynamics with a pulsating prominence.

Right Ventricle Rupture After Open Heart Surgery.

The potential complications of cardiac surgery with sternotomy include mediastinitis and major bleeding, events that are infrequent but carry high mortality.We report a unique complication of median sternotomy. A 71-year-old man underwent coronary artery bypass grafting complicated by sternal dehiscence on postoperative day 7. One week after discharge, he presented with purulent drainage from the sternal wound bed and was diagnosed as having mediastinitis. Irrigation, debridement, and sternal reconstruction were performed. Two days later, bleeding was observed in the wound, and during surgical exploration, a tear in the right ventricle was discovered, and the patient exsanguinated and died. Autopsy findings included focal adhesions connecting the posterior sternum to the right ventricle wall, as well as microscopic evidence of focally extensive fatty infiltration along the rupture margin of the myocardium.Pertinent aspects of the case are reviewed, with particular attention to the possible microbial etiology of mediastinal infection and most likely mechanisms of injury contributing to the fatal right ventricular rupture.

Surgical Removal of Migrated Broken Sternal Wire Using Endoscopic Assistance.

Patients undergoing sternotomy routinely undergo sternal closure with stainless steel wires. Occasionally these wires can fracture, although normally this presents no concern as the broken wire remains fixed and is not problematic. We report a case of a segment of a broken sternal wire that migrated through the pericardium onto the right ventricular. It was removed with a minimally invasive approach with endoscopic assistance.

An abnormal left ventricular-atrial perforation after radiofrequency catheter ablation: a case report.

BACKGROUND: Cardiac radiofrequency ablation is a popular treatment for arrhythmias. However, it does have some complications, some of which are severe, even fatally. And there were limited reports on cardiac internal perforation after radiofrequency catheter ablation (RFCA) that required a surgical repair. CASE PRESENTATION: A 47-year-old male was admitted to our hospital due to chest congestion for 4 months. He received a radiofrequency catheter ablation (RFCA) 9 months prior to admission. On admission, an echocardiogram showed an abnormal perforation between the left ventricle and the left atrium with moderate mitral valve regurgitation. We therefore performed a mitral valve replacement (MVR) and fixed the abnormal atrial-ventricular breakage via median sternotomy. CONCLUSIONS: Cardiac perforation is a severe complication of cardiac RFCA, operators should be extremely cautious to minimize radiofrequency associated perforations. Such a challenging and complex procedure should be deliberately considered by doctors and patients before implementation.
