Outcomes with Toronto stentless porcine aortic valve: the Australian experience.

The purpose of this study is to describe the Australian experience with TSPV in the aortic position in 543 patients followed for up to 8 years. Prospectively collected data were reviewed. The average age was 73.

Mitral valve repair: a clinical and echocardiographic study.

Objective: To evaluate the clinical and echocardiographic results of mitral valve repair done within an 11 year period.

Design: Retrospective review of case notes and clinical and echocardiographic examination of survivors. Analysis was made according to the intention to treat principle.

Early berry aneurysm formation in Marfan's syndrome.

A detailed study of cerebral arterial forks by serial sectioning was made in a 33-year-old woman with typical Marfan's syndrome who died of septicemia following cardiac surgery. Two forks of the right middle cerebral artery exhibited the atrophic changes associated with early berry aneurysm formation indicating that the mode of development of these aneurysms is similar in both Marfan's syndrome and in non-Marfan subjects.

Late results of valve replacement and factors influencing survival in patients with severe chronic mitral regurgitation.

Between July 1967 and September 1981 50 patients with isolated severe mitral regurgitation underwent mitral valve replacement. There were 29 males and 21 females (mean age 52 years). The aetiology of the valve lesion was rheumatic in 14 patients (mean age 42 years) and non-rheumatic in 36 patients (mean age 56 years).

Peripheral early stage lung cancer: superiority of six-monthly over random chest films.

An analysis of 100 biopsy-proven lung cancers found by chance chest films and treated by resection have been collected over a 20 year period. Data relating to sex of patients, smoking habits, age groups, lung and lobar sites, cell type, treatment and survival are stated and discussed in relation to the findings of a known planned study for detecting early stage lung cancer by chest films. It is concluded that, if a person at lung cancer risk is genuinely interested in having regular checks to catch early, operable disease, then his chances are best with six-monthly chest films.
