Background: The incidence of coronary artery bypass graft surgery (CABG) performed in elderly patients has been increasing over recent years. We sought to evaluate clinical outcomes of octogenarians undergoing CABG using an audited state-wide mandatory database.
Methods: New York State Department of Health's Cardiac Reporting System was analyzed from 1998 to 2002.
Objective: Primary repair of tetralogy of Fallot with absent pulmonary valve syndrome has been associated with significant mortality, particularly for neonates in respiratory distress. Controversy persists regarding the method of establishing right ventricle-pulmonary artery continuity.
Methods: Anatomic and demographic parameters were evaluated for patients undergoing repair of tetralogy of Fallot with absent pulmonary valve syndrome from 1990 to 2005, as were perioperative and late postoperative parameters (airway complications, reoperation or catheter-based intervention, and mortality).
Background And Aim: The current shortage of donor hearts has forced the criteria of organ procurement to be extended, leading to increased use of older donor hearts to bridge the gap between demand and availability. Our objective was to analyze the effect of donor age on outcomes after cardiac transplantation.
Methods: We retrospectively studied 864 patients who underwent cardiac transplantation at New York Presbyterian Hospital - Columbia University between 1992 and 2002.
Objective: The use of left ventricular assist devices as a bridge to transplantation for patients with chronic congestive heart failure is well accepted. However, few studies have examined outcomes solely for these patients. This study details one center's left ventricular assist device experience with this population.

Methods And Results: We analyzed 55,515 patients from New York State database who underwent CABG between 1997 and 1999.
Background: The use of artificial chords for the replacement of diseased mitral valve chordae and the correction of anterior and posterior leaflet prolapse is well described, although it is infrequently applied because of technical challenges.
Methods: A simplified approach to attaching the new chords to a single papillary muscle base within the left ventricle has been reported, and we present a series of 13 patients with moderate-severe mitral regurgitation (MR) who underwent chordal replacement using this improved technique.
Results: The MR grade by echocardiogram improved from 3.
Objectives: We reviewed our experience with repair of truncus arteriosus to assess the effect of type of right ventricular outflow tract reconstruction on perioperative morbidity, survival, and freedom from catheter-based interventions and reoperation.
Methods: Patients undergoing repair of truncus arteriosus from June 1990 through February 2004 were evaluated on the basis of operative procedure regarding preoperative and postoperative variables, the need for postoperative catheter-based intervention or reoperation, and survival on the basis of univariate, multivariable, and actuarial analyses.
Results: Of 54 study patients, 15 (28%) received a valved homograft, and 39 (72%) received a direct connection with a variety of hood materials.
Background: Cardiac transplantation for patients with complex congenital heart disease poses several anatomic and physiologic challenges for the transplant surgeon. We undertook the current single center study to evaluate surgical outcomes and lessons learned through a nearly twenty year experience with cardiac transplantation for complex congenital heart disease.
Methods: A retrospective review was performed to evaluate all patients undergoing cardiac transplantation from January 1, 1984 through January 1, 2004.
