Introduction and Case Presentation: A 44-year-old female patient suffered migraines and underwent contrast-enhanced transcranial Doppler (c-TCD). During the rapid injection of contrast agent, she suffered chest tightness, palpitation, decreased consciousness, perimouth numbness, and headache, respectively. Meanwhile, "curtain" pattern of air embolic signals lasted up to 115 seconds in her decreased right middle cerebral artery accompanied with arrhythmia. The microair embolic signals lasted as long as 340 seconds. The patient's symptoms were relieved in 30 minutes. The aforementioned symptoms and signs occurred, lasted, then disappeared coinciding in time with changes of microbubbles. The woman was later found to have ventricular septal defect. Discussion: The adverse effects to cardiac-neurovascular system of c-TCD are reported for the first time, which arouse attention to safety of the procedure.

Imaging Studies for Cardiovascular System V: CT01:28

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Imaging Studies for Cardiovascular System IV: CMRI

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Cardiac Catheterization IV: Nursing Management

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

Imaging Studies VII: Vascular Imaging

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
