TL;DR: Intravascular ultrasound may be used to evaluate compliance in patients with coronary artery disease and is mainly determined by the arterial site and by the presence, size and characteristics of plaque on intrav vascular ultrasound imaging.

TL;DR: Intravascular ultrasound imaging (IVUS) constitutes a new diagnostic technique that provides unique information concerning arterial wall structure and luminal dimensions and demonstrated the presence of plaque in 16 patients at 19 different angiographic sites.

TL;DR: Intravascular ultrasound can be performed rapidly and safely and could serve as an alternative or adjunct diagnostic procedure in patients with aortic dissection and in the description of associated pathologic changes that may be clinically important.

TL;DR: No increase in lumen calibre was evident on ultrasound after PTCA, but coronary flow reserve measured with intracoronary Doppler did improve and the patient remained stable and free of angina following the procedure.
Abstract: We describe a case of spontaneous coronary artery dissection that gave rise to post infarction unstable angina. An ambiguous angiographic appearance was shown by intracoronary ultrasound to arise from an extensive coronary dissection. The dissection membrane separating true and false lumina and features to suggest sluggish flow and early thrombosis in the false lumen were observed. No increase in lumen calibre was evident on ultrasound after PTCA (probably a consequence of the relatively large ultrasound catheter blank), but coronary flow reserve measured with intracoronary Doppler did improve and the patient remained stable and free of angina following the procedure.

TL;DR: Intravascular ultrasound (IVUS) imaging of the coronary arteries has recently been introduced for the study of coronary lesions, but the angiographic effects produced by an IVUS examination before coronary angioplasty are unknown and could not predict the feasibility of the IVUS study.

TL;DR: The sensitivity in the diagnosis of cardiac myxomas is similar with both techniques, but transesophageal echocardiography is much more accurate in the detection of the precise attaching point and the presence of satellite tumours.
Abstract: INTRODUCTION AND OBJECTIVES Transthoracic echocardiography is the gold-standard method in the diagnosis of cardiac myxomas. Our aim was to analyze the usefulness of transesophageal echocardiography in the diagnosis and assessment of patients with cardiac myxomas. PATIENTS AND METHODS From 1990 to 1992, 14 patients underwent cardiac surgery with the echocardiographic diagnosis (transthoracic and/or transesophageal approach) of cardiac myxomas. Thirteen (86%) of the 14 patients had after surgery histological confirmation of myxoma. Of the 13 myxomas, 10 were located in the left atrium and 3 in the right atrium. RESULTS Transthoracic echocardiography was able to diagnose the presence of myxoma in 12 of the 13 patients, whereas the transesophageal approach detected all of them. The precise attaching point of the tumour was seen in 9 patients with transthoracic echocardiography and in all the patients with the transesophageal approach. Also the presence of satellite tumours seen in 2 patients was only detected by transesophageal echocardiography. CONCLUSION We conclude that the sensitivity in the diagnosis of cardiac myxomas is similar with both techniques, but transesophageal echocardiography is much more accurate in the detection of the precise attaching point and the presence of satellite tumours. We think that TEE is a useful tool, complementary to TTE, in the assessment of patients with cardiac myxomas before going to surgery.

TL;DR: A patient with a right atrial myxoma and a very unusual and life‐threatening complication: infection with resultant bacteremia is described.
Abstract: Myxomas, the most common primary cardiac tumors, rarely become infected. This report describes a patient with a right atrial myxoma and a very unusual and life-threatening complication: infection with resultant bacteremia. The few cases reported in the literature are reviewed. The relevance of transesophageal echocardiography (TEE) in the diagnosis and assessment of atrial masses is emphasized.
