Mitral valve stenosis ) can cause a precipitous decrease in cardiac output and sudden congestive heart failure. Patients with mitral stenosis prompts a series of hemodynamic changes that frequently cause deterioration of the patient's clinical status. A reduction in cardiac output, associated with acceleration of heart rate and shortening of the diastolic time, frequently leads to congestive heart failure. In addition, when AF sets in, systemic embolization becomes a real danger. Mitral stenosis typically progresses slowly (over decades) from the initial signs of mitral stenosis to NYHA functional class II symptoms to the development of atrial fibrillation to the development of NYHA functional
Mitral valve prolapse valve. The prevalence of MVP is estimated at 2–3% of the population. The condition was first described by John Brereton Barlow in 1966. In consequence, it may also be referred to as Barlow's syndrome, and was subsequently termed "mitral valve prolapse" by J. Michael Criley. Upon auscultation of an individual with mitral valve prolapse, a mid-systolic click, followed by a late systolic murmur heard best at the apex is common. The length of the murmur signifies the time period over which blood is leaking back into the left atrium, known as regurgitation. A murmur that lasts throughout the whole of
