In mitral incompetence the left ventricle has two exits and it has been suggested that diminished resistance to emptying causes left ventricular systole to be shorter than normal (Brigden and Leatham, 1953). Theoretically the elevation of left ventricular end-diastolic pressure that is found in severe mitral incompetence (Ross et al., 1958; Nixon, 1961a) should result in prolongation of systole...

BACKGROUND Both an impaired capacity to increase heart rate during exercise testing (chronotropic incompetence), and a slowed rate of recovery following exercise (heart rate recovery) have been shown to be associated with all-cause mortality. It is, however, unknown which of these responses more powerfully predicts risk, and few data are available on their association with cardiovascular mortal...

OBJECTIVE The purpose of this study was to compare second-trimester transvaginal cervical cerclage with conservative management on duration of pregnancy and perinatal outcome in patients with early or advanced cervical changes. STUDY DESIGN A historical cohort analysis was performed. Maternal and neonatal records between 1995 and 1999 were retrospectively reviewed for women presenting between...

A 44-year-old man presented with cardiogenic shock secondary to acute functional mitral incompetence as well as septic shock related to pneumonia. The patient deteriorated haemodynamically despite adequate medical therapy. An echocardiogram revealed a massive mitral incompetence and an ejection fraction of 32%. An intra-aortic balloon pump was placed and the patient improved dramatically. On da...

The early onset of isolated aortic incompetence in a male child with HLA B27 and peripheral arthritis is reported. Acute anterior uveitis and lone aortic incompetence occurred at 1 and 9 months respectively after the development of the acute inflammatory arthritis. The uveitis resolved with local therapy and the arthritis remitted 10 months after the onset. There has been no recurrence of the a...

INTRODUCTION continuous wave Doppler (CWD) has good discriminatory power at the groin in the assessment of saphenous femoral junction (SFJ); however, it is not as accurate as duplex ultrasound scanning (DUS) in the popliteal fossa for assessment of saphenous popliteal junction (SPJ) in patients with primary short saphenous vein incompetence. AIM the aim of this study was to compare the findin...

Mitral incompetence appearing in connexion with acute coronary heart disease without papillary muscle rupture has not received much attention until recently. Castex (1933) presented eight patients with electrocardiographic findings of inferior myocardial infarction and with an apical murmur of mitral incompetence as a distinct clinical syndrome. Nezlin and Shamesova (1951) paid attention to the...

OBJECTIVE To investigate the functional significance of chronotropic incompetence during dobutamine stress echocardiography. PATIENTS AND METHODS The functional significance of chronotropic incompetence was evaluated during dobutamine stress echocardiography in 512 patients without beta blocker treatment who underwent dobutamine stress echocardiography (up to 40 microg/kg/min) and completed t...
