The device consists of four parts (Fig 1). The disposable mouthpiece (Inspiron No. 001200) fits into one end of a 6inch corrugated tube (Hudson Corr-A-Tube II, No. 1410). The other end of this tube is coupled to a connector (BardParker oxygen hose connector No. 5002) via a 22 X 22-mm adapter (Bard-Parker No. 5095). This connector fits snugly onto the male hub of the rubber tubing of most commer...

We present a possible alternative technique to treat the rupture of aortic arch aneurysms on beating heart without necessity of cardiopulmonary bypass (CPB), hypothermic circulatory arrest and cerebral protection, using a bifurcated vascular prosthesis to revascularize the subclavian and carotid arteries and an endovascular prosthesis to repair the aortic arch. We report the case of a 78-year-o...

We describe an unusual case of left ventricular outflow tract (LVOT) pseudoaneurysm late after aortic valve replacement. A 77-year-old man, who had undergone aortic valve replacement with mechanical prosthesis 7 years ago, presented, asymptomatic, with a transesophageal echocardiography (TTE) diagnosis of a large cavitary mass arising behind the aortic wall. The orifice of the pseudoaneurysm wa...

OBJECTIVE Early and medium-term improvement of functional capacity and regression of left ventricular hypertrophy was evaluated in the young adult patient group following application of 21 mm or 23 mm bileaflet aortic mechanical valve prosthesis due to aortic stenosis. Methods : Twenty two patients (10 male, 12 female; mean age 27+-8.2 (19-43)) who underwent isolated aortic valve replacement du...

BACKGROUND Cardiovascular Magnetic Resonance is often used to evaluate patients after heart valve replacement. This study systematically analyses the influence of heart valve prostheses on phase contrast measurements in a phantom trial. METHODS Two biological and one mechanical aortic valve prostheses were integrated in a flow phantom. B0 maps and phase contrast measurements were acquired at ...

Details are presented concerning 59 patients who left hospital between January 1964 and January 1969 after aortic valve replacement with the Starr-Edwards prosthesis. Of the 14 late deaths, 7 are known to have been due to causes related to the prosthesis and 4 to other causes. The 45 surviving patients have nearly all shown clinical improvement and only 3 are unable to work as a result of some ...

A 57-year-old Chinese male patient presented with Standford type A aortic dissection with an aberrant right subclavian artery (ARSA). At operation, the ascending aorta was replaced by a mono-branch vascular prosthesis with the branch bypassing to the ARSA; the triple-branched stent graft was inserted into the true lumen of the arch and proximal descending aorta (covering the origin of the ARSA)...

Transfemoral aortic valve implantation (TAVI) has become an important interventional technique for patients with severe aortic stenosis (AS) and very high surgical risks. Several studies have demonstrated the feasibility and clinical success of TAVI procedures.1,2 Indications of transfemoral implantations of aortic valves are clearly defined, and TAVI should only be performed in patients with s...

A fifty eight year old man with Marfan's syndrome and an aortic composite graft with a Björk-Shiley mechanical prosthesis presented with a large aortic root abscess caused by Staphylococcus aureus endocarditis. Despite extensive surgical debridement and implantation of an aortic homograft as a composite graft, early postoperative transoesophageal echocardiography continued to demonstrate a larg...

After follow up for seven years a 10 year old boy with congenital aortic regurgitation was found to have a tricuspid non-stenotic aortic valve at operation. The right coronary cusp was dysplastic, thickened, and contracted; the gap between its free margin and aortic wall was bridged with two fibrous bands; and the left coronary and non-coronary cusps were almost normal. The aortic valve was rep...
