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...
BACKGROUND Pulmonary insufficiency is the nexus of late morbidity and mortality after transannular patch repair of tetralogy of Fallot. This study aimed to establish the feasibility of implantation of the novel Medtronic Harmony transcatheter pulmonary valve (hTPV) and to assess its effect on pulmonary insufficiency and ventricular function in an ovine model of chronic postoperative pulmonary i...
The electrocardiograms in 32 patients with mitral valve disease have been compared with the pulmonary resistances, the pulmonary artery pressures, and the size of the mitral valve orifice. In patients with pure stenosis if the electrocardiogram showed the pattern of right ventricular hyper-trophy the total pulmonary resistance was usually 1000 dynes seconds cm.-5 or greater. If mitral insuffici...
Introduction: Retinal vein occlusion is a common vascular disorder disrupting vision. Two basic types of RVO are branch retinal vein occlusion and central retinal vein occlusion (CRVO). Retinal vein occlusion is a multifactor process including systemic illness and local retinal factors.RVO may be associated with atherosclerotic risk factors. We analyzed the role of 2 dimensional transthor...
The authors describe an unusual case of a young adult patient with symptomatic tricuspid valve insufficiency as a late consequence of pulmonary valve balloon dilatation in childhood. Patient was successfully treated by tricuspid valve repair with neo-chordae implantation and a ring plasty. Two years after the operation the patient, an active sportsman, is asymptomatic with trace tricuspid regur...
T HE PATHOGENESIS of congestive failure is still uncertain. In 1910 Bolton and Starling (I) wrote that the analysis of the factors involved in the production of the disease was rendered difficult by the impossibility of accurately reproducing these states in animals. Since that time numerous methods have been tried to precipitate congestive failure in dogs. The attempts have met with limited su...
cardiac hydatid cyst (chc) is a rare disease that was endemic in some regions especially in sheep-raising areas. the most commonly accepted theory for the routes of heart involvement in hydatid cyst was infestation by the hexacanthus embryo through coronary arteries. here, we describe a case with the primitive cardiac hydatid cyst located around the pulmonary valve (pv) and main pulmonary arter...
A bicuspid aortic valve (BAV) demonstrating moderate valvular stenosis and mild insufficiency was identified in an asymptomatic 1-year-old male cryptorchid English bulldog by transthoracic and transesophageal echocardiography. The BAV was most consistent with type 3 morphology, based upon human classification. Pulmonary valve dysplasia with mild pulmonary stenosis and a suspected persistent lef...

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...
