Effects of mitral valve surgery on static lung function and exercise performance.

The patients with the greatest symptomatic improvement in breathlessness were also those who achieved the greatest increase in maximum work load and the greatest decrease in ventilation for a given oxygen consumption.

Ventilatory anaerobic threshold before and after cardiac valve surgery.

The purpose of this study was to objectively assess exercise tolerance before and after cardiac valve surgery by using an objectively determined ventilatory anaerobic threshold (AT). Nine patients

Reduced exercise capacity in patients with tricuspid regurgitation after successful mitral valve replacement for rheumatic mitral valve disease.

Clinically significant tricuspid regurgitation may develop late after successful mitral valve replacement and in the absence of residual pulmonary hypertension, prosthetic dysfunction, or significant left ventricular impairment.

The various types of exercise tests, the response to exercise in both normal subjects and patients with lung disease and the role of exercise testing with reference to therapeutics are discussed.

Physical training after heart valve replacement.

The exercise programme modified the recovery of "cardiorespiratory fitness" after operation, and suggested that sequential exercise tests are of value after cardiac surgery.

The cardiac response to exercise in aortic valvular disease before and after ball valve replacement.

. Cardiac output, stroke volume, “exercise factor” and maximal arterial oxygen transport during upright exercise have been determined in seven patients with aortic valvular disease before and after

The Maximal Oxygen Intake Test in Patients with Predominant Mitral Stenosis: A Preoperative and Postoperative Study

It was inherent in the work by Hickam and Cargill over a decade ago and in subsequent studies by Gorlin and co-workers that resting hemodynamic and respiratory studies might be of limited value in the functional evaluation of patients with mitral stenosis unless combined with exercise studies.

Clinical and Hemodynamic Studies in Patients with Homograft Mitral Valve Replacement

Results of valve replacement with mitral homografts in the 120 patients who have had operation at the Stanford Medical Center from May 1967 to November 1970 are given, indicating that fresh homografted replacement of the mitral valve provides good long-term clinical and hemodynamic benefit in most patients.

Heart valve surgery in 114 patients over the age of 60.

It was concluded that age alone should not be regarded as a contraindication to surgical treatment in those patients who are severely incapacitated from chronic valve disease.

An analysis of the physiological strain of submaximal exercise in patients with chronic obstructive bronchitis.

This study has shown that major disturbances in cardiopulmonary function can be demonstrated without the need for stressing a patient to the limit of his effort tolerance.

Cardiorespiratory adaptations at the start of exercise in normal subjects and in patients with chronic obstructive bronchitis.

The rate of adaptation of VE at the start of exercise is (in common with that of fH, Vo 2 and Vco 2 ) reduced in proportion to the overall reduction in working capacity.

Functional results with aortic ball valve prostheses (Starr-Edwards) followed for two to three years.

The aim of this paper is to report the 'long-term' clinical and haemodynamic results with this valve.
