Male adolescent with cardiac rupture after blunt thoracic trauma.

Blunt cardiac injury, including a rupture of the atria or ventricle, is most commonly caused by motor vehicle collisions and falls from great heights. A rupture of a cardiac chamber is an extremely rare diagnosis with a high mortality rate. The best chance at survival can only be accomplished with timely intervention.To raise awareness of this potentially life-threatening injury, we describe the case of a male adolescent with cardiac rupture after blunt thoracic trauma. While the focused assessment with sonography in trauma (FAST) examination was negative, an additional CT showed pericardial effusion. During the operation a rupture of the right ventricle was observed.Even though the physical recovery of our patient is remarkable, the traumatic event still affects his mental well-being and activities in daily life. This case emphasises the need of a multidisciplinary approach to achieve the best possible physical and psychological recovery in multitrauma patients.

[Traumatic Right Atrial Rupture with Left Hemothorax but without Hemopericardium:Report of a Case].

Traumatic cardiac rupture is mostly accompanied by tamponade and/or hemopericardium. We experienced a rare case of traumatic right atrial rupture with left hemothorax, but without hemopericardium. A 36-year-old male had a traffic accident, and was transported to our hospital. He was in a state of shock caused by massive hemothorax. He underwent emergency operation through median sternotomy. No blood was seen in the pericardium nor injury of any major vessels or lungs. When the heart was exposed, massive bleeding occurred. A tear of 30 mm in length was found in the right atrium at the junction of the superior vena cava. The tear was repaired under cardiopulumonary bypass. Even after surgery, however, he remained unconscious.

Ultrasound to Localize the Peripherally Inserted Central Catheter Tip Position in Newborn Infants.

OBJECTIVE: This study aimed to evaluate the application of ultrasound for the localization of the tip position of peripherally inserted central catheters (PICCs) in newborn infants. STUDY DESIGN: This study was a retrospective analysis on ultrasonic localization for PICC placement conducted in our department over the past 2 years. Ultrasonic localization was performed immediately after PICC placement in all neonatal patients. Successful PICC placement was confirmed if the PICC tip position was located at the inferior/superior cavoatrial junction. Chest X-ray localization was performed on 32 infants immediately after ultrasound examination to compare the accuracy of ultrasound localization. RESULTS: Of the 186 patients, 174 (93.5%) had successful PICC placement on the first attempt. In 11 (5.9%) patients, the catheter tip was placed beyond the ideal location as follows: too deep (in the right atrium) in 4 patients, too shallow in 4 patients, and malpositioned in 3 patients. Both the sensitivity and the specificity of ultrasound for identifying PICC tip localization were 100%. Complications occurred in 2.7% of this group of patients. CONCLUSION: Ultrasonic localization of the PICC tip position is a timely, accurate, and reliable method and can identify the catheter tip with high accuracy. This method could be widely applied in neonatal wards.

Iliac vein stent migration with extensive cardiac damage in a patient with May-Thurner syndrome.

In May-Thurner syndrome, or iliac vein compression syndrome, the left common iliac vein is compressed between the right common iliac artery and corresponding vertebral body, increasing patient risk for deep vein thrombosis. Iliac vein stenting for patients with symptomatic May-Thurner syndrome has become standard practice in many centers. This article describes a patient whose stent embolized completely to the right ventricle, destroying most structures in its path.

Left atrium perforation with lung injury after catheter ablation.

Left atrial perforation is a known complication following pulmonary vein catheter ablation. Our case of a 62-year-old female underwent urgent surgery for repair of left atrium perforation with left pleural effusion as a late complication after multiple transcatheter radiofrequency pulmonary vein ablations for persistent atrial fibrillation.

Case report and systematic review of iatrogenic left atrial dissection in different cardiovascular specialties: A common treatment for an uncommon complication?

OBJECTIVES: Left atrial dissection (LatD) is a rare and heterogeneous condition affecting many cardiovascular areas. The present article, by the means of personal case report illustration and systemic review of different clinical management, is aimed to give to clinicians further knowledge on this controversial topic. BACKGROUND: LatD is an exceedingly rare but potentially fatal complication of cardiac surgery or catheter-based interventional procedures. Most of the cases are iatrogenic and its incidence is expected to grow due to an increase in the number of percutaneous coronary intervention and structural heart disease procedures. The management of this complication is controversial, and it may depend on related etiologies. METHODS: We have reported our single-case experience and review of the scientific literature, focusing on the decision-making process and the strategical approach by multimodality imaging techniques. RESULTS: Our case of LatD with initial hemodynamic instability was surgically treated. Conservative approach is often employed in literature despite the fact that conservative versus surgical approach is debatable, depending on clinical presentation, hemodynamic stability, multimodal imaging findings, and personal experience of the center. CONCLUSIONS: According to systematic literature review, a watchful-waiting strategy supported by multimodality imaging could be a safe and effective management in stable LatD.

Two cases of pericardial tamponade due to nitinol wire fracture of a gore septal occluder.

Percutaneous patent foramen ovale (PFO) closure is recommended for secondary prevention of paradoxical embolism through a PFO. In the United States, two Food and Drug Administration-approved PFO closure devices are currently available, and the choice depends on operator preference and PFO anatomy. Although these devices are easy to implant, there are several potential complications. As opposed to the Amplatzer PFO Occluder, there has been no published case of atrial erosion with Gore closure devices. This report describes two cases of pericardial tamponade due to perforation of the atrial wall induced by a wire frame fracture of the Gore Helex and Cardioform devices.

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.

Myosin binding protein H-like (MYBPHL): a promising biomarker to predict atrial damage.

Myosin binding protein H-like (MYBPHL) is a protein associated with myofilament structures in atrial tissue. The protein exists in two isoforms that share an identical amino acid sequence except for a deletion of 23 amino acids in isoform 2. In this study, MYBPHL was found to be expressed preferentially in atrial tissue. The expression of isoform 2 was almost exclusively restricted to the atria and barely detectable in the ventricle, arteria mammaria interna, and skeletal muscle. After atrial damage induced by cryo- or radiofrequency ablation, MYBPHL was rapidly and specifically released into the peripheral circulation in a time-dependent manner. The plasma MYBPHL concentration remained substantially elevated up to 24 hours after the arrival of patients at the intensive care unit. In addition, the recorded MYBPHL values were strongly correlated with those of the established biomarker CK-MB. In contrast, an increase in MYBPHL levels was not evident in patients undergoing aortic valve replacement or transcatheter aortic valve implantation. In these patients, the values remained virtually constant and never exceeded the concentration in the plasma of healthy controls. Our findings suggest that MYBPHL can be used as a precise and reliable biomarker to specifically predict atrial myocardial damage.

Primary cardiac angiosarcoma with right atrial wall rupture: A case report.

RATIONALE: Cardiac angiosarcoma is the most common malignant tumor of the heart and a rare disease with rapid disease progression and poor prognosis. Cardiac wall rupture is an extremely rare complication. PATIENT CONCERNS: A 32-year-old woman presented with an acute onset of epigastric pain and chest discomfort at first time when she visited an emergency room. DIAGNOSES: A cardiac mass was identified on echocardiography and subsequently performed chest computed tomography and cardiac magnetic resonance imaging revealed the cardiac tumor at right atrium with right atrial wall rupture and hematogenous lung metastasis. Histopathologic diagnosis of metastatic angiosarcoma was done by open lung biopsy. INTERVENTIONS: The patient was treated with palliative chemotherapy for the primary cardiac tumor and hematogenous lung metastasis. OUTCOMES: The follow-up imaging studies revealed treatment response of the primary cardiac tumor and hematogenous lung metastasis. LESSONS: Clinical and radiologic evaluation of the cardiac angiosarcoma was well performed in our case with various diagnostic imaging modalities including echocardiography, chest computed tomography, cardiac magnetic resonance imaging, and fluorodeoxyglucose-positron emission tomography/computed tomography. This case report well demonstrates typical imaging findings of a rare cardiac tumor and emphasizes importance of early investigation for accurate diagnosis and proper management of the cardiac tumor.

Atrial-Esophageal Fistula After Catheter Ablation: Diagnosing and Managing a Rare Complication of a Common Procedure.

BACKGROUND Atrial fibrillation is considered the most common cardiac arrhythmias in the United States with rate and rhythm control strategies traditionally used for management. If patients are intolerant to class I or class III anti-arrhythmic medications, catheter ablation may be used as a rhythm control strategy. As catheter ablation becomes more commonplace, so too do the procedure-related complications, which include tamponade, total arterio-venous fistula, pulmonary vein stenosis, and atrial-esophageal fistula. CASE REPORT A 67-year-old male underwent catheter ablation for atrial fibrillation and subsequently presented with complaints of fever and chills. Initial workup for a source of infection included a computed tomography (CT) scan and transesophageal echocardiogram which did not reveal any abnormalities. Antibiotic therapy was initiated, and multiple CT scans were performed; eventually patient was found to have an atrial-esophageal fistula, secondary to thermal injury. The patient underwent thoracotomy and full thickness necrosis of the posterior left atrium and pericardium near the base of the left inferior pulmonary vein was visualized, with a roughly nickel sized orifice, which was repaired. The patient had an uneventful recovery and was doing well on follow-up. CONCLUSIONS Atrial-esophageal fistula is a rare but lethal complication of atrial fibrillation ablation. While imaging modalities have improved and can detect the condition, they can also yield ambivalent findings which can challenge patient care. It is important for clinicians to maintain a heightened awareness of this complication in post-ablation patients and utilize clinical history and not rely solely on imaging to diagnose and treat this complication.
