Spectral Doppler interrogation of the descending thoracic and abdominal aorta provides valuable information regarding cardiac and vascular hemodynamics. An abnormal aortic Doppler profile is encountered in pathological conditions that affect the aorta and its branches, the aortic valve, the left ventricle, and the pericardium. Characteristic findings on Doppler interrogation of the aorta are often noted in individuals with obstructive atherosclerotic disease of the aorto-iliac system including severe stenosis or occlusion of the distal aorta and/or iliac arteries. In this manuscript, we highlight the findings on spectral Doppler that led to the identification of occlusive disease in the distal aorta.

“…Many imaging studies for assessing AAA can also identify other diseases that could affect pre-operative management of AAA, such as coronary artery disease [23] and thoracic aortic aneurysm [24]. Screening for AAA can also be performed during unrelated imaging studies, such as transthoracic echocardiography [25][26][27][28], peripheral vascular US [29], and imaging studies to assess coronary artery disease [30,31] and stroke or transient ischemic attack [32]. Aortic root size measured by transthoracic echocardiography has been shown to be an independent predictor of AAA [33].…”

Clinical palpation of a pulsating abdominal mass alerts the clinician to the presence of a possible abdominal aortic aneurysm (AAA). Imaging studies are important in diagnosing and categorizing the extent of the aneurysm and may aid in treatment planning. The consensus of the literature supports the use of ultrasound as the initial screening test in patients with suspected AAA. Population-based ultrasound screening studies have been recommended and have proved effective for male patients > 65 years of age. For diagnosis and pre-intervention evaluation, either multidetector CT or CT angiography is the optimal choice for detailed characterization of the aneurysm. MR angiography may be substituted if CT cannot be performed (for example, because the patient is allergic to iodinated contrast material). Invasive angiography has little role in the diagnosis of AAA and PET and CT remain experimental in patients with suspected aneurysms. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer-reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

The Various Hemodynamic Profiles of the Patent Ductus Arteriosus in Adults

The patent ductus arteriosus (PDA) has diverse clinical and hemodynamic manifestations depending on its size and the degree of the ensuing left-to-right shunt. A small PDA that causes minor shunting has no major hemodynamic consequences. Conversely, a large PDA with a significant left-to-right shunt may lead to various hemodynamic abnormalities. These include left-sided volume overload that may result in heart failure and/or pulmonary hypertension, the latter being a flow-dependent and mostly reversible phenomenon. The most feared complication is the development of severe and irreversible pulmonary hypertension (Eisenmenger physiology). In this manuscript, we provide examples of the various hemodynamic profiles of PDA as assessed by echocardiography in the adult population.
