Capnography has been studied for decades as a potential diagnostic tool for suspected pulmonary embolism. Despite technological refinements and its combination with other non-invasive instruments, no evidence to date allows recommending the use of expired carbon dioxide measurement as a rule-out test for pulmonary embolism without additional radiological testing. Further ...

OBJECTIVE: The purpose of this study was to determine whether the view used, multiplanar or axial, for image interpretation at pulmonary CT angiography for suspected acute pulmonary embolism alters the diagnostic confidence, accuracy, and interpretation time of cardiothoracic radiology specialists and radiology residents. MATERIALS AND METHODS: Patients who underwent 50 ...

Although multidetector computed tomographic (MDCT) pulmonary angiography has found widespread use in the evaluation of acute pulmonary embolism, advances in technology have allowed for its application in realms that were previously exclusive to conventional pulmonary angiography. In this article, the authors address the use of MDCT in the evaluation of ...

Currently, the only widely accepted indication for thrombolysis in cases of pulmonary embolism is hemodynamic instability. However, the presence of a right-heart thrombus along with pulmonary embolism is a poor prognostic indicator, and the use of thrombolytic agents should also be considered in this circumstance. Furthermore, despite a risk of ...

A respirophasic variation of the QRS complex was observed in a patient with bilateral pulmonary embolism and pulmonary hypertension. An analogous variation of the Sa systolic velocity of the tricuspid annular tissue Doppler imaging was also noticed. Both phaenomena persisted until the clinical and haemodynamic improvement of the patient. A ...

There are many treatment modalities available to acutely terminate incessant ventricular tachycardia with variable success rates, but some cases tend to prove refractory to all of them. We report a 59-year-old woman presenting with incessant ventricular tachycardia. Echocardiography revealed a large true apical aneurysm and severe left ventricular dysfunction. The ...

Pulmonary embolism is a common cardiovascular emergency, but it is still often misdiagnosed due to its unspecific clinical symptoms. Elevated troponin concentrations are associated with greater morbidity and mortality in patients with pulmonary embolism. Right ventricular ischemia due to increased right ventricular afterload is believed to be underlying mechanism of ...

Recently, CT pulmonary angiography (CTPA), especially performed with multi-detector row CT, has become a key imaging modality for pulmonary embolism. However, CTPA that was performed under clinical suspicion of pulmonary embolism has been shown to lead to high prevalence of alternative diagnosis, up to 25.4%. A comprehensive evaluation of pulmonary ...

Intimal sarcoma of the pulmonary artery (PAS) is a rare but potentially lethal tumour, frequently misdiagnosed as chronic thrombo-embolic pulmonary artery disease. Despite the availability of advanced imaging technologies, its preoperative diagnosis remains difficult. We report on two patients with clinical features mimicking chronic pulmonary thrombo-embolism. Further discussion will focus ...

STUDY OBJECTIVE: Acute pulmonary embolism can produce abnormalities on ECG that reflect severity of pulmonary hypertension. Early recognition of these findings may alter the estimated pretest probability of pulmonary embolism and prompt more aggressive treatment before hemodynamic instability ensues, but it is first important to test whether these findings are ...

Central venous catheters (CVCs) are commonly used in clinical practice. One of the foremost complications associated with their use is the potential for symptomatic or asymptomatic thrombosis. CVC thrombosis, in turn, may not only result in vascular and catheter occlusion but also infection, pulmonary embolism, and formation of right heart ...

The authors are developing a computer-aided detection system for pulmonary emboli (PE) in computed tomographic pulmonary angiography (CTPA) scans. The pulmonary vessel tree is extracted using a 3D expectation-maximization segmentation method based on the analysis of eigen-values of Hessian matrices at multiple scales. A parallel multiprescreening method is applied to ...

By considering studies where a mixing of patients with and without shock, with or without invasive procedure, treated with various thrombolytic agents through different ways of infusion, have been included, current meta-analyses on thrombolysis efficacy in Pulmonary embolism (PE) are of limited value. Modern management of PE includes the use ...

Many prognostic models have been developed to help physicians make medical decisions on treating patients with pulmonary embolism. Among these models, the Pulmonary Embolism Severity Index (PESI) has been shown to be a successful risk stratification tool for patients with acute pulmonary embolism. The PESI, however, had not been applied ...

Percutaneous vertebroplasty (PVP) is a therapeutic, interventional radiological procedure involving bone cement injection into a vertebral body. Although PVP is considered a minimally invasive procedure, cement leakage into the perivertebral venous system can occur with its migration towards the right heart and the pulmonary circulation. We report a case of ...

Free-floating intracardiac thrombi represent a severe yet uncommon condition and mostly coexist with thromboembolism. Notably, mobile right heart thrombus can occur in patients with massive pulmonary embolism. Early diagnosis and management can be life-saving. Spontaneous atrial thrombosis due to restrictive cardiomyopathy has also been rarely reported. We describe here an ...

Despite the high incidence of pulmonary embolism its diagnosis continues to be difficult, primarily because of the vagaries of symptoms and signs in presentation. Conversely, syncope is a relatively easy clinical symptom to detect, but has varied etiologies that lead to a documented cause in only 58% of syncopal events. ...

Percutaneous vertebroplasty is a useful and safe therapeutic intervention to stabilize vertebral fractures. Rarely, cement leakage into the paravertebral venous system may result in embolization of its particles into the right cardiac chambers and pulmonary artery. We experienced a case of a 64-year-old woman who was diagnosed through echocardiography as ...

In this report, we describe a patient who contracted fatal cryptococcosis after the induction of hemodialysis. A 76-year-old man was hospitalized to initiate hemodialysis. On admission, clinical findings showed no signs of any infections, and hemodialysis was inducted favorably. On the 6th hospital day he suddenly had a dyspnea and ...

We describe a case which highlights the difficulties in diagnosing pulmonary embolism as it can mimic other conditions. In a patient with chest pain with raised troponin, a diagnosis of pulmonary embolism should also be considered as well if the clinical picture does not fit with myocardial infarction. Otherwise, the ...

Fatal pulmonary embolism following a shoulder joint replacement is a rare event. The exact prevalence of shoulder arthroplasties is not clear. Unlike hip and knee joint replacements where some form of thromboprophylaxis is routinely prescribed, no such guidelines and practice exist for shoulder replacements. Other case reports have confirmed fatal ...
