Abstract		Echocardiography is increasingly performed in patients with suspected pulmonary embolism because of the wide accessibility and possibility of performing it at the bedside. In hemodynamically compromised patients, this method is providing a rapid diagnosis and immediate therapy and could exclude other causes of shock, including aortic dissection, pericardial tamponade and left or right ventricular infarction. The main role of transthoracic echocardiography is to reveal any signs of acute right ventricular pressure overload and hypokinesis and increased pulmonary arterial pressure. Transesophageal echocardiography enables a direct diagnosis of pulmonary embolism, with the possibility of direct visualisation of blood clots in the proximal parts of both pulmonary arteries. In patients with acute pulmonary embolism, signs of acute right ventricular pressure overload and hypokinesis are associated with a worse prognosis and are important for deciding on the type of therapy.
Summary		UZ-pregled srca se pri bolnikih s sumom na pljučno embolijo vse pogosteje uporablja zaradi široke dostopnosti in možnosti, da preiskavo opravimo ob bolnikovi postelji. Pri hemodinamsko nestabilnih bolnikih omogoča najhitrejšo diagnostično pot do takojšnjega zdravljenja in lahko izključi druge vzroke šokovnega stanja, kot so aortna disekcija, tamponada in infarkt levega ali desnega prekata. S transtorakalno ehokardiografijo lahko ugotavljamo znake akutne tlačne obremenitve in zmanjšanje krčljivosti desnega prekata ter zvišan pritisk v pljučni arteriji, s transezofagealno ehokardiografijo pa lahko pljučno embolijo potrdimo neposredno z dokazom strdkov v proksimalnem delu obeh pljučnih arterij. Znaki akutne tlačne obremenitve in zmanjšane krčljivosti desnega prekata pri bolniku s pljučno embolijo so kazalci slabše prognoze in so pomembni za odločitev o načinu zdravljenja.
