BACKGROUND Off-pump coronary artery bypass graft surgery (OPCAB) has been performed for many years, but its use is increasing in frequency, and it remains an open question whether OPCAB is associated with better outcomes than on-pump coronary artery bypass graft (CABG) surgery. METHODS AND RESULTS New York State patients who underwent either OPCAB with(More)
BACKGROUND Patients with severe atheromatous aortic disease (AAD) who undergo coronary artery bypass (CABG) have an increased risk of death and stroke. We hypothesized that in these high risk patients, off-pump coronary artery bypass (OPCAB) technique is associated with lower morbidity and mortality. METHODS AND RESULTS Between June 1993 and January 2002,(More)
BACKGROUND Studies that are the basis of recommended volume thresholds for CABG surgery are outdated and not reflective of recent advances in the field. This study examines both hospital and surgeon volume-mortality relations for CABG surgery through the use of a population-based clinical data set. METHODS AND RESULTS Data from New York's clinical CABG(More)
8 The information contained in this booklet is intended for health care providers, patients and families of patients who are considering cardiac surgery. It provides data on risk factors associated with in-hospital deaths following coronary artery bypass and/or heart valve surgery and lists hospital and physician-specific mortality rates which have been(More)
BACKGROUND No simplified bedside risk scores have been created to predict long-term mortality after coronary artery bypass graft surgery. METHODS AND RESULTS The New York State Cardiac Surgery Reporting System was used to identify 8597 patients who underwent isolated coronary artery bypass graft surgery in July through December 2000. The National Death(More)
BACKGROUND Restriction of volume-based referral for CABG surgery to high-risk patients has been suggested, and earlier studies have reached different conclusions regarding volume-based referral for low-risk patients. METHODS AND RESULTS Patients who underwent isolated CABG surgery in New York from 1997 through 1999 (n=57 150) were separated into low-risk(More)
1 We are very pleased to provide the information in this booklet for health care providers and for the families of children who need heart surgery. This report summarizes outcomes for pediatric patients undergoing surgery to correct congenital heart defects. Hospital-specific mortality rates that have been adjusted to account for differences in patient(More)
BACKGROUND The survival difference between off-pump and on-pump coronary artery bypass graft surgery for follow-up longer than 5 years is not well-understood. The objective of this study is to examine the difference in 7-year mortality after these 2 procedures. METHODS AND RESULTS The state of New York's Cardiac Surgery Reporting System was used to(More)
INTRODUCTION Although minimally invasive aortic valve surgery (MIAVR) is performed in many centers, few studies have compared its results to a standard sternotomy (SS) approach. We assessed the hypothesis that, when compared with SS in the elderly population, MIAVR has similar morbidity and mortality and allows faster hospital recovery. METHODS AND(More)
Isolated noncompaction of the left ventricle is a congenital cardiomyopathy, which has been described recently, with literature limited to case reports and case series. Even though various complications have been reported with noncompaction cardiomyopathy, among them severe mitral regurgitation has been reported recently in a few cases. There is no great(More)
