Added value of 18 F-FDG-PET/CT and cardiac CTA in suspected transcatheter aortic valve endocarditis

ConclusionsAddition of18F-FDG-PET/CT and/or CTA changed the final diagnosis in 33% of patients and proved to be a valuable diagnostic tool in patients with suspected TAVI-IE.

By MICHEL ACCAD Last month marked the 400th anniversary of the birth of John Graunt, commonly regarded as the father of epidemiology.  His major published work, Natural and Political Observations Made upon the Bills of Mortality, called attention to the death statistics published weekly in London beginning in the late 16th century.  Graunt was skeptical of how causes of death were ascribed, especially in times of plagues.  Evidently, 400 years of scientific advances have done little to lessen his doubts!  A few days ago, Fox News reported that Colorado governor Jared Polis ...

Abstract Cardiovascular diseases are the most common cause of death in patients over 60 years old. Imaging methods of a pivotal role in cardiological diagnostic processes are echocardiography, magnetic resonance, multi-row-detector computed tomography, coronary angiography, and radioisotope tests. In this paper, we summarize the techniques of nuclear medicine (positron emission tomography, single-photon emission computed tomography, radionuclide ventriculography) that could be implemented in the cardiovascular diagnostic algorithms. Despite being acknowledged and positioned in a few cardiological guidelines, these...

A 73-year old man presented with a posterolateral ST-elevated myocardial infarction 9 months after biological aortic valve replacement for aortic valve stenosis. Invasive coronary angiography showed a filling defect across the left main coronary artery bifurcation extending into the left anterior descending artery and the ramus circumflex. Transthoracic echocardiography revealed a thickened prosthesis leaflet with signs of slight stenosis. Cardiac computed tomography angiography showed a mass on the left coronary cusp of the valve prosthesis, suggestive for vegetation or thrombus. The scan also revealed central luminal fil...

We present a novel, life-threatening complication: an acute, noninfectious TPV thrombosis. Within 24 hours after implantation of a Melody system (Medtronic, Inc, Minneapolis, MN), the patient developed an acute TPV thrombosis characterized by severe TPV stenosis on echocardiography and contrast filling defects on computed tomography pulmonary angiography images. Genetic testing revealed heterozygous prothrombin G20210A polymorphism and homozygous 4G/4G polymorphism of the plasminogen-activator-inhibitor. The patient recovered after surgical valve replacement with a pulmonary homograft.RésuméLe remplacement de...

In this report, we report a 38-year-old female suffering from intermittent fever and was later diagnosed as IE. Initially antibiotic was given and mitral valve surgery was also arranged due to large vegetation with severe mitral regurgitation. Nevertheless, sudden conscious loss with desaturation happened and brain computed tomography (CT) showed intracranial and subdural hemorrhage related to possible septic embolism. In addition, electrocardiography (ECG) revealed ST elevation over precordial leads, and elevation of cardiac enzymes was also noted. Diagnoses: Emergent coronary angiography was arranged but result showed...

Acute complications following TPV implantation include infective endocarditis, stent fracture and device dislocation. Herein, we present a novel, life-threatening complication: an acute, non-infectious TPV thrombosis.Within 24 hours after implantation of a Melody® system, our patient dev...

ConclusionsThis study demonstrates that the evaluated imaging-in-endocarditis-flowchart is applicable in daily clinical practice. Echocardiography, MDCTA, and FDG-PET/CT provide relevant complementary diagnostic information, particularly in patients with intracardiac prosthetic material.

This report describes a case of bleeding pulmonary arterial pseudoaneurysm in a young, drug-addicted woman with tricuspid annuloplasty after infective endocarditis that was promptly identified by computed tomography pulmonary angiography and successfully treated using coil embolization. Perfusion scintigraphy at 30 days confirmed the safety of endovascular treatment.
