  • Aortic stenosis occurs in about 2% of people over 65 years of age. (medlineplus.gov)
  • Why this aging process progresses to cause significant aortic stenosis in some patients but not in others is unknown. (digestivetracthealth.com)
  • Aortic valve stenosis (also called aortic stenosis or AS) is a condition where the heart's aortic value has narrowed. (cprtampa.training)
  • The severity of the condition determines aortic stenosis treatment. (heartscope.com.au)
  • Aortic stenosis can cause chest pain, fainting, and heart failure leading to shortness of breath. (digestivetracthealth.com)
  • This chest pain is caused by the higher pressure needed to pump blood through the damaged aortic valve and oxygen demand of the thickened muscle. (cprtampa.training)
  • Although TAVR has less than 10-year experience with valve durability, it has lower or noninferior primary end points, such as mortality and stroke, and fewer periprocedural complications among anatomically permissive patients. (acpjournals.org)
  • In patients with severe aortic stenosis (AS), atrial fibrillation (AF) is associated with increased long-term mortality after aortic valve replacement (AVR), which may be due to unfavorable hemodynamics in AF. (kssg.ch)
  • PRJEB60931) with a rocking motion of the prosthetic valve sug- against a custom database ( 8 ) using Kraken 2 ( 9 ) and gesting disinsertion, without vegetations (Figure). (cdc.gov)
  • Surgery or a catheter procedure may be needed to fix the valve. (msdmanuals.com)
  • It is a catheter-based procedure which is performed by the interventional cardiologist and cardiac surgeon for patients with calcified, narrowed aortic valve (aortic valve stenosis). (yashodahospitals.com)
  • In the procedure, the cardiologist inserts or squeezes the valve along the catheter. (yashodahospitals.com)
  • Edwards' Sapien aortic valve is made from bovine pericardial tissue and is implanted via a catheter-based delivery system. (wikipedia.org)
  • The transfemoral approach requires the catheter and valve to be inserted via the femoral artery. (wikipedia.org)
  • The transapical approach sees the catheter and valve inserted through the tip of the heart and into the left ventricle. (wikipedia.org)
  • An adjusted analysis was performed to compare the early clinical safety outcome according to the Valve Academic Research Consortium-2 definition. (123dok.net)
  • A complication of strep throat infection, rheumatic fever may result in scar tissue forming on the aortic valve. (gh.ge)
  • Rheumatic fever may damage more than one heart valve, and in more than one way. (gh.ge)
  • Scarring of the aortic valve due to rheumatic fever as a child or young adult. (digestivetracthealth.com)
  • The third cause of aortic stenosis is damage from rheumatic fever. (cprtampa.training)
  • A doctor suspects aortic valve stenosis after detecting a particular heart murmur and sometimes a clicking sound when listening to the heart. (msdmanuals.com)
  • A heart murmur is a sound created by turbulent blood flow through narrowed or leaking heart valves or through abnormal heart structures. (msdmanuals.com)
  • Doctors often hear a heart murmur using a stethoscope, a vital sign of aortic stenosis. (heartscope.com.au)
