Angiographically borderline left main coronary artery lesions: correlation of transthoracic doppler echocardiography and intravascular ultrasound: a pilot study
BACKGROUND the clinical decision making could be difficult in patients with borderline lesions (visually assessed stenosis severity of 30 to 50%) of the left main coronary artery (LM). The aim of the study was to evaluate the relationship between transthoracic Doppler (TTDE) peak diastolic flow velocity (PDV) and intravascular ultrasound (IVUS) measurements in the assessment of angiographically...
متن کاملCoronary 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 کاملEnhanced coronary flow velocity during intra-aortic balloon pumping assessed by transthoracic Doppler echocardiography.
OBJECTIVES The study was done to determine potential utility of measuring coronary flow velocity (CFV) by transthoracic Doppler echocardiography (TTDE) during intra-aortic balloon pumping (IABP). BACKGROUND Use of IABP has been shown to increase CFV assessed by an invasive technique. The CFV in the left anterior descending coronary artery (LAD) can be measured by TTDE. METHODS Coronary flow...
متن کاملComparison between M-Mode and Doppler echocardiography in diagnosis
Introduction: Patent ductus arteriosus (PDA) is the persistence of a normal fetal structure between left pulmonary artery and descending aorta. Persistence of this fetal structure beyond 10 days of life is considered abnormal. In this study we compared M-Mode and Doppler echocardiography in diagnosis of PDA in children at Aliasghar Hospital in Zahedan and Children hospital in Bandar Abbas for...
