Abstract

The Carpentier-McCarthy-Adams IMR ETlogix annuloplasty ring was specifically designed to treat ischemic mitral regurgitation (IMR) associated with asymmetric mitral annular dilation and leaflet tethering. The study aim was to review, retrospectively, the results of mitral annuloplasty with this asymmetric ring in a representative number of patients. Between January 2005 and July 2012, the IMR ETlogix ring was implanted in 190 consecutive patients (mean age 69.5 +/- 7.6 years) with grade > or =2+ IMR (graded from 0 to 3+). Preoperatively, 37 patients (19.5%) were in NYHA class IV, and 73 (38.4%) suffered from unstable angina. The operative risk according to the European System for Cardiac Operative Risk Evaluation II was 15.6 +/- 14.5%. Using two- dimensional echocardiography, postoperative changes in mitral annular diameter (MAD) and tenting height (TH) of the mitral valve in four-chamber, two-chamber and long-axis views, were assessed at mid-systole. Thirty-eight patients (20.0%) received one or more concomitant major cardiac surgical procedure(s) other than, or in addition to, coronary artery bypass grafting or tricuspid valve annuloplasty. Nineteen (10.0%) hospital deaths occurred, and one patient underwent immediate reopera...Continue Reading

Cardiac Remodeling

Cardiac remodeling in response to a myocardial infarction is characterized by progressive ventricular dilatation, cardiac hypertrophy, fibrosis, and deterioration of cardiac performance. Discover the latest research on Cardiac Remodeling here.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
