Coronary hemodynamics and regional myocardial metabolism in experimental aortic insufficiency.
Acute aortic valvular insufficiency was induced in open chest dogs by employing a special intravascular cannula, or by rupturing an aortic valve leaflet. Phasic and mean coronary flow were assessed in some animals, while in others data were obtained on arterial and coronary sinus blood lactate, pyruvate, P(O2), P(CO2), and pH, and on myocardial tissue lactate, pyruvate, and water content in the...
متن کاملUncommon Doppler echocardiographic findings of severe pulmonic insufficiency.
BACKGROUND Two-dimensional and Doppler echocardiography are standard methods to assess the severity of pulmonic insufficiency (PI). However, methods to define severity of PI - including the current published guidelines - remain qualitative and unvalidated. METHODS We reviewed all the electronic reports of echocardiographic studies performed at our institution since the publication of the 2003...
متن کاملThe phonocardiographic differentiation of pulmonic and aortic insufficiency.
PATIENTS presenting with high-pitched diastolic decrescendo murmurs along the left sternal border may have insufficiency of either the aortic or pulmonary semilunar valve. If the peripheral pulses are those of aortic insufficiency in type, the source of the diastolic murmur is located easily. However, in the absence of both the peripheral physical signs of aortic insufficiency and the electroca...
متن کاملPINOT NOIR: Pulmonic INsufficiency imprOvemenT with Nitric Oxide Inhalational Response
BACKGROUND Tetralogy of Fallot (TOF) repair and pulmonary valvotomy for pulmonary stenosis (PS) lead to progressive pulmonary insufficiency (PI), right ventricular enlargement and dysfunction. This study assessed whether pulmonary regurgitant fraction measured by cardiovascular magnetic resonance (CMR) could be reduced with inhaled nitric oxide (iNO). METHODS Patients with at least moderate P...
متن کاملTricuspid insufficiency. A study of hemodynamics and pathogenesis.
The clinical diagnosis of the presence and severity of tricuspid insufficiency is difficult and is complicated by the transient nature of this abnormality as well as its usual occurrence in subjects with other valve disease. This paper presents correlative hemodynamic data from 100 consecutive catheterized patients with valvular heart disease in 90 of whom the presence of tricuspid insufficienc...
