A 83-year-old Caucasian male, known with chronic pulmonary disease, mild renal insufficiency, hypertension and epilepsy, was admitted to our tertiary referral centre for aortic valve replacement because of symptomatic severe aortic stenosis. Echocardiography showed aortic stenosis with a peak gradient of 100 mmHg (aortic valve area 0.5 cm2) and a hypertrophic left ventricle with moderate systol...

splenomegaly-induced thrombocytopenia is fully described in hematological and surgical literature, but its association with severe aortic stenosis is rare. we present a case of severe aortic valve stenosis with severe splenomegaly-induced thrombocytopenia in which aortic valve replacement was done with a number 23 homograft and splenectomy was performed after the end of cardiopulmonary bypass. ...

OBJECTIVE Midterm follow-up is analyzed after the aortic translocation (Nikaidoh) procedure, an alternative to the Rastelli procedure for ventriculoarterial discordance, ventricular septal defect, and pulmonary stenosis. METHODS Nineteen patients underwent a Nikaidoh procedure at a median age of 3.3 years (0.9-9.3 years). The native aortic valve was translocated from the right to the left ven...

INTRODUCTION AND OBJECTIVES Percutaneous aortic valve implantation for patients with severe symptomatic aortic stenosis and a high surgical risk is currently well established. We report our experience in terms of safety and effectiveness of transcatheter aortic valve implantation in other clinical context like the degenerated aortic homografts. METHODS We report our initial experience in four...

Results of long-term follow-up of an early cohort of patients receiving aortic valve homografts for aortic stenosis and aortic insufficiency are presented. All patients were operated upon by a single surgeon from 1966 to 1971. Eighty-three patients underwent insertion of 85 homograft aortic valves. Homografts were sterilized with either betapropiolactone (39 valves) or gamma irradiation (41 val...

A 60-year-old man with a history of endocarditis presented with congestive heart failure New York Heart Association class III symptoms. He did not have any signs or symptoms of microembolic phenomenon and the blood cultures were negative. A transesophageal echocardiogram showed an eccentric jet of mitral regurgitation (MR) from a perforation in the anterior mitral valve leaflet (MVL) (Fig. 1, V...

The study of patients with aortic insufficiency has revealed that many demonstrate a first degree The possible advantages of this P-R prolongation have only recently been described (Herbert, 1967). It appears that such a mechanism enables the left atrium to contract earlier (relative to ventricular systole) and thus deliver its volume contribution to forward flow before the premature closure of...

transcatheter aortic valve implantation (tavi) is a new therapeutic option for patients with severe aortic stenosis with unacceptable surgical risk for conventional aortic valve surgery. a bicuspid aortic valve (bav) is the most common congenital cardiac disorder (1% of the population) and currently is considered exclusion criteria for tavi, because it predicts an increased risk of adverse aort...

We described a new technique (called ‘bicuspidization’), which is performed by using autogenous material, without replacement of the aortic valves for the surgical treatment of aortic stenosis and/or insufficiency and tested it in in vitro sheep model. Different stress conditions were simulated by applying three different flow patterns (hemodynamic challenge tests) successively by using a centr...
