II-24 Arrythmias following cardiac valve replacement

Arrhythmias following cardiac valve replacement.

A prospective study of 50 consecutive patients undergoing cardiac valve replacement was designed to determiine the incidenice, types, and predisposing factors to postoperative arrhythmias. Patients were monitored continuously for the first 7 days following surgery. Thirty-seven patients (74%) experienced a total of 66 episodes of arrhythmia. Supraventricular arrhythmias were the most common (43...

Cardiac valve replacement--an update.

Even though artificial heart valve implants have a history of some 30 years, there is to this day no ideal valve substitute. Each of the categories of substitutes used has its own advantages as well as problems. Since my last review on the subject, that appeared in this journal, was some 13 years ago (Lim, 1977), it is perhaps appropriate to provide an update on the status of cardiac valve repl...

Prosthetic valve leakage following cardiac valve replacements.

Thirty cases were evaluated in order to study the etiology of prosthetic valvular dehiscence in view of its continued occurrence in a small percentage of cases. The clinical course, management, initial valvular pathology, as well as findings at reoperation and necropsy were the main basis of this study. Factors in the genesis of prosthetic valvular dehiscence in the early and late groups seemed...

Serial cardiac output and blood volume studies following cardiac valve replacement.

[Left ventricular rupture following mitral valve replacement].

Rupture of the posterior wall of the left ventricle is an unusual but often lethal complication following mitral valve replacement. The incidence is about 1% of MVRs. Most of the ruptures are attributed either to technical maneuvers in the operation or to stretch injury produced by removal of the mural leaflet of the mitral valve. Surgical repair of the rupture requires the cardiopulmonary bypa...
