Quick Access

If considering catheter ablation as a treatment option, pre-procedure planning can involve use of MR or CT imaging to identify anatomical targets for the procedure and understand the extent of AF. These images can help guide decisions on necessity of left atrial appendage closure in certain populations.

Interventional system use should be optimized for clinical success while helping to minimize contrast and radiation exposure to patient and clinician. After an ablation, regular patient follow up and non-invasive imaging assessment may detect potential return of Atrial Fibrillation.

Time to intervention can be a risk: delays to reperfusion correlate with higher rates of mortality and morbidity. Approximately 80 percent of all CVD deaths are due to heart attacks. Time is critical for patients who present with acute chest pain, with or without cardiac history. By integrating with MUSE, data from home-based patients will be made available to clinicians on the same clinical workspace they use every day.

The ability to send observations and test results wirelessly can be invaluable to attending physicians and interventional lab preparations — potentially enabling fast action upon arrival to aid quality patient outcomes such as door to balloon time. There are many potential causes of chest pain.

For patients not sent immediately to the interventional lab for revascularization, guidelines suggest use of biomarkers, clinical history, ECG and non-invasive imaging measurement results, and other factors, to determine TIMI risk score which in turn can guide revascularization decisions. There are available estimates for sensitivity and specificity for the various non-invasive tests to diagnose the presence of CAD, but other factors are frequently considered such as equipment availability and patient tolerance. For patients sent for revascularization in the catheterization lab, attempts are made to rapidly access the culprit artery and complete further assessment of coronary tree.

Rapid intervention can help minimize time to reperfusion from first medical contact. Follow-up treatment and rehabilitation strategies typically include non-invasive monitoring of LV function and strain.

Among symptomatic patients with medically treated moderate-to-severe aortic stenosis, mortality from the onset of symptoms is approximately 25 percent at one year and 50 percent at two years. Time is critical for AS patients who present with significant cardiac issues. Due to the high mortality rates by the time patients are symptomatic, it is important to identify patients at risk, even when they are asymptomatic. Echocardiography can identify issues or abnormalities related to Aortic Valve structure and function.

Diagnosis involves assessment of valve morphology, amount of stenosis or insufficiency, LV function, LV hypertrophy, and severity of symptoms. For patients with Aortic Stenosis, there are surgical and catheterization treatment options in addition to medical or palliative care. A risk calculator is typically used to quantify the risk and make a treatment decision. For patients choosing a transcatheter replacement, non-invasive cardiovascular imaging, such as Ultrasound, CT, and MR are typically used to assess anatomy to plan the access site and size the valve.

During the transcatheter aortic valve replacement, steps are taken to ensure the most effective result, including valve sizing, position, and function are optimal.

Additionally, the need for contrast media reduction e. Therefore, we want to equip you with the appropriate means such as our low kV capabilities or Tin Filter, e. Identify significant coronary artery disease with the HeartFlow FFR CT Analysis Functional CT strategies offer additional incremental accuracy for detecting hemodynamically significant Coronary Artery Disease among patients with intermediate stenosis compared with anatomical assessment alone.

This is achieved by the incremental improvement in specificity and positive predictive value afforded by e. CT Cardiovascular imaging.

Cardiac Magnetic Resonance Imaging (MRI) Basic Principles (Dipan Shah, MD) Sep. 29, 2015

Watch the video on the left to discover the benefits of dynamic myocardial perfusion. Clinical Use. Image courtesy of Siemens Healthineers. September 17, — The U. September 12, — HeartFlow Inc. September 9, — The American Society of Haojie Wang, M. His hospital installed a dedicated cardiac Siemens 1. Traditionally, computed tomography CT and ultrasound have been the workhorse imaging modalities in the world of This puts the technology on equal footing with the previous standard-of-care of open heart surgery, representing a paradigm shift in cardiology.

September 3, — Here is the list of the most popular content on the Diagnostic and Interventional Cardiology Displacement comparison at the end-systolic frame and final frame. The three patients V6, V10, V16 with different left-ventricle walls are shown. Point-to-surface distance is a measure to estimate the distance of a point from the reference surface.
