• surgical
  • This surgery includes a simple replacement of the aortic and mitral valves with biological or mechanical prostheses in the context of isolated interventions on the heart valves or in combination with the surgical treatment of other heart diseases (e.g. bypass). (bookinghealth.com)
  • Treatment of damaged valves may involve medication alone, but often involves surgical valve repair (valvuloplasty) or replacement (insertion of an artificial heart valve). (wikipedia.org)
  • intrathoracic
  • An elevation in pulmonary insufficiency due to elevated intrathoracic pressure is relevant in ventilated patients (having acute restrictive right ventricular physiology). (wikipedia.org)
  • Inhalation leads to an increase in intrathoracic negative pressure, which increases the capacity of pulmonary circulation, thereby prolonging ejection time. (wikipedia.org)
  • causes
  • Causes of aortic insufficiency in the majority of cases are unknown, or idiopathic. (wikipedia.org)
  • Dysfunctions involving the pulmonary, cardiovascular or neuromuscular systems have been frequently found to be associated with exercise intolerance, with behavioural causes also playing a part. (wikipedia.org)
  • Other potential causes that affect the valve directly include Marfan syndrome, Ehlers-Danlos syndrome, ankylosing spondylitis, and systemic lupus erythematosus. (wikipedia.org)
  • Aortic insufficiency causes both volume overload (elevated preload) and pressure overload (elevated afterload) of the heart. (wikipedia.org)
  • coronary
  • the development of minimally invasive surgery related to both coronary and valves (on which he organized two international conferences in 1997 and 1998) and development of conservation valves techniques in collaboration with the American professor Tirone David. (wikipedia.org)
  • There are also the coronary sinus and the inferior vena cava valves. (wikipedia.org)
  • prevent backflow
  • The valves incorporate leaflets or cusps, which are pushed open to allow blood flow and which then close together to seal and prevent backflow. (wikipedia.org)
  • commonly
  • The four valves commonly represented in a mammalian heart determine the pathway of blood flow through the heart. (wikipedia.org)
