Coronary artery fistula diagnosed by transthoracic Doppler echocardiography.
A 47-year-old Malay woman complained of an episode of shortness of breath after a shower. There was no previous complaint of shortness of breath or chest pain. Physical examination revealed a wide pulse pressure. Blood pressure was 160/66 mmHg, and heart rate was 77/minute and regular. What was initially thought to be a loud pansystolic murmur was heard over the precordium. Electrocardiography ...
متن کاملCoronary Flow Reserve Measurement by Transthoracic Doppler Echocardiography
Introduction Coronary flow reserve (CFR) is defined as a ratio of maximal (stimulated) to baseline (resting) coronary blood flow. CFR evaluation is important for the understanding of the pathophysiology of coronary circulation. CFR measurement is used both to assess epicardial coronary stenoses and to examine the integrity of microvascular circulation. An appreciation of coronary physiology is ...
متن کاملTraumatic Esophageal Injury Detected by Transthoracic Echocardiography
A 65-year-old man was admitted to our hospital after being injured in a motor vehicle accident. Fractures of the sternum and right tibia were diagnosed and surgical bone repair was planned. Preoperative transthoracic echocardiography (TTE) revealed an unusual round-shaped mass with a central high echoic lesion, measuring 2-3 cm in diameter, behind the left atrium (Picture 1). Contrast-enhanced ...
متن کاملCoronary artery occlusions diagnosed by transthoracic Doppler
BACKGROUND Our aim was to assess whether anterograde flow velocities in septal perforating branches could identify an occluded contralateral coronary artery, and to assess the feasibility and accuracy of diagnosing occlusions in the three main coronary arteries by the combined use of several noninvasive parameters indicating collateral flow. METHODS A total of 108 patients scheduled for coron...
متن کاملAssessment of coronary flow velocity with transthoracic Doppler echocardiography during dobutamine stress echocardiography.
OBJECTIVES The purpose of this study was to evaluate the feasibility of measuring coronary flow velocity (CFV) by transthoracic Doppler echocardiography (TTDE) in the left anterior descending coronary artery (LAD) during contrast-enhanced dobutamine stress echocardiography (DSE). We also assessed the value of TTDE for detecting stress-induced myocardial ischemia in the LAD territory. BACKGROU...
