2. Aortic stenosis - Wikipedia

   en.wikipedia.org/wiki/Aortic_stenosis

   Aortic stenosis is most commonly caused by age-related progressive calcific aortic valve disease (CAVD) (>50% of cases), with a mean age of 65 to 70 years. CAVD is the build-up of calcium on the cusps of the valve, and this calcification causes hardening and stenosis of the valve. [ 22 ]

3. Wiggers diagram - Wikipedia

   en.wikipedia.org/wiki/Wiggers_diagram

   A Wiggers diagram, named after its developer, Carl Wiggers, is a unique diagram that has been used in teaching cardiac physiology for more than a century. [1] [2] In the Wiggers diagram, the X-axis is used to plot time subdivided into the cardiac phases, while the Y-axis typically contains the following on a single grid: Blood pressure. Aortic ...

4. Coronary artery bypass surgery - Wikipedia

   en.wikipedia.org/wiki/Coronary_artery_bypass_surgery

   To more accurately determine the severity of stenosis, interventional cardiologists may also employ intravascular ultrasound, which can determine the severity and provide information on the composition of the atheromatous plaque. With the technique of fractional flow reserve, the pressure after the stenosis is compared to mean aortic pressure ...

5. Acute coronary syndrome - Wikipedia

   en.wikipedia.org/wiki/Acute_coronary_syndrome

   Chest pain with features characteristic of cardiac origin (angina) can also be precipitated by profound anemia, brady-or tachycardia (excessively slow or rapid heart rate), low or high blood pressure, severe aortic valve stenosis (narrowing of the valve at the beginning of the aorta), pulmonary artery hypertension and a number of other ...

6. Aortic valve - Wikipedia

   en.wikipedia.org/wiki/Aortic_valve

   Using TTE, the degree of stenosis and insufficiency can be quantified to grade the valve dysfunction. Transesophageal echocardiography is less often used for aortic stenosis & insufficiency because the angle between the probe and the aortic valve is not optimal (the best window is a transgastric view). MRI and CT can be used to evaluate the ...

7. Hypertrophic cardiomyopathy - Wikipedia

   en.wikipedia.org/wiki/Hypertrophic_cardiomyopathy

   In individuals with aortic stenosis or with HCM with an outflow tract gradient, there will be a pressure gradient (difference) between the left ventricle and the aorta, with the left ventricular pressure higher than the aortic pressure. This gradient represents the degree of obstruction that has to be overcome in order to eject blood from the ...

8. Heyde's syndrome - Wikipedia

   en.wikipedia.org/wiki/Heyde's_syndrome

   Heyde's syndrome; A stenotic aortic valve: Specialty: Cardiology, general surgery, Hematology: Symptoms: Aortic valve stenosis symptoms: Chest pain (angina) or tightness Shortness of breath, especially during exertion or when lying down Fatigue or weakness Irregular heartbeat or heart palpitations Dizziness or fainting episodes Gastrointestinal bleeding symptoms: Occult (hidden) or overt ...

9. Shock (circulatory) - Wikipedia

   en.wikipedia.org/wiki/Shock_(circulatory)

   Aortic stenosis hinders circulation by obstructing the cardiac output. Hypertrophic sub-aortic stenosis is overly thick ventricular muscle that dynamically occludes the ventricular outflow tract . Abdominal compartment syndrome defined as an increase in intra-abdominal pressure to > 20 mmHg with organ dysfunction. [ 14 ]
