A round echogenic structure is already visible at the top of the left atrial appendage. After administration of a bolus of 0.5 mL SonoVue a contrast filling defect appears in this area as a sign of a thrombus. With a mechanical index of 0.09 (Vivid 7, 6TC probe, CPI (Coded Phase Inversion)) there is no…
apical hypertrophic cardiomyopathy
Sorry, this entry is only available in german! Neben der Wandbewegungsanalyse und dem Thrombusnachweis stellt die apikale hypertrophe Kardiomyopathie eine weitere wichtige Indikation für eine Kontrastmittel verstärkte Echokardiographie dar. So wird in der aktuellen Leitlinie der ACCF/AHA von 2011 für die Diagnose und Behandlung der hypertrophen Kardiomyopathie (http://circ.ahajournals.org/content/early/2011/11/07/CIR.0b013e3182n23e2bd.citatio) als Klasse IIaC -Indikation angeführt: ” Die…
thrombus left atrium, example 1
A patient with a CRT-D device has presented himself initialy with the clinical picture of a device infection 4 weeks ago. Device and electrodes have been removed and an antibiotic therapy has been initiated. The patient presents now with a worsening of heart failure without fever but slightly elevated leucocytes and CRP values. The video…
left ventricular chamber
Sorry, this entry is only available in german Die folgenden Videos stammen von einem Patienten, der 8 Tage zuvor einen Myokardinfarkt erlitten hatte. Bei einem Gewicht von über 130 kg und einer Körpergröße von 165 cm ist eine Aussage zur systolischen Funktion und zum Vorhandensein eines Thrombus nicht möglich: Links oben 4 Kammerblick, rechts oben…
atrium
Transesophageal echocardiography plays a key role in the selection of suitable patients for cardioversion. If a transesophageal echocardiography is conducted prior to cardioversion of a patient with a persistent non-valvular atrial fibrillation, we expect in 12 % of the patients a thrombus in the left atrial appendage (Antithrombotic therapy in atrial fibrillation, American College of…
left ventricular opacification (LVO)
One of the most important and most common indications for ultrasound contrast agents is improvement of endocardial border delineation. The following example shows a left ventricle with an apical aneurysm. Using a mechanical index of 0,06 with the M5S probe and the Vivid E 9 platform there is no apical swirling but a very good…
