OBJECTIVE For the surgical treatment of congenital heart disease and in Ross procedure a valved conduit is frequently required. Since homografts are not readily available in every country, a reliable alternative is needed. We developed a novel technique to construct a valved pulmonary conduit with single point attached commissures (SPAC) in a simple and fast way from a small strip of autologous...

A 39-year-old man with no known cardiovascular risk factors was hospitalized for chest pain radiating to the side. Type A aortic dissection was diagnosed by transthoracic echocardiography and computed tomography (CT). which the ascending aorta was replaced with a valved tube graft (Bentall-Bono procedure). The patient had a phenotype typical of Marfan disease: height of 190 cm, long limbs, scol...

INTRODUCTION Patients with congenital heart disease who underwent pulmonary valvotomy or surgery to open the pulmonary valve ring are prone to develop residual pulmonary insufficiency or stenosis that may lead to right heart failure with clinical deterioration. These children require multiple interventions throughout their lives, which impose a high rate of morbidity and mortality. OBJECTIVE ...

This feasibility study was conducted to evaluate design features of the novel intraurethral valved catheter, Surinate (Urovalve, Inc; Newark, New Jersey). The device extends from the bladder neck to just beyond the external sphincter and contains a valve that can be activated by an external magnet for bladder emptying. Five patients were recruited from the Edward Hines Jr Department of Veterans...

Nebulizers convert solutions or suspensions into aerosols with a particle size that can be inhaled into the lower respiratory tract. There are pneumatic jet nebulizers, ultrasonic nebulizers, and mesh nebulizers. Newer nebulizer designs are breath-enhanced, breath-actuated, or have aerosol-storage bags to minimize aerosol loss during exhalation. Nebulizers can be used with helium-oxygen mixture...

Between January 1983 and March 1988 25 patients with aneurysms of the ascending aorta were operated, out of these only 15 (56%) electively. Acute incompetence (10) were the main indications for operation. Poststenotic aneurysms (2), mycotic (2) and saccular sclerotic (1) aneurysms have also been observed. A rare case of a ruptured ascending aorta due to histologically and serologically proven B...
