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. In all, 88,154 patients undergoing isolated CABG were identified. Patients were divided into four age groups: less than 50 years (group 1, n=6,527), 50 to 64 years (group 2, n=30,088), 65 to 79 years (group 3, n=43,369), and 80 years and above (group 4, n=8,170). Results Of all patients, 9.3% were octogenarians. In addition to marginally worse coronary artery disease, octogenarians generally manifested a higher incidence of preoperative risk factors such as cerebrovascular disease, peripheral vascular disease, and congestive heart failure compared with younger patients at baseline. Both length of hospital stay and in-hospital mortality rate were significantly higher among octogenarians. The incidence of postoperative complications was higher among octogenarians. Multivariate analysis demonstrated renal failure requiring dialysis (odds ratio [OR] = 4.4), myocardial infarction within 6 hours before surgery (OR = 3.6), chronic obstructive pulmonary disease (OR = 1.7), congestive heart failure at admission (OR = 1.7), emergent operation (OR = 1.6), Canadian Cardiovascular Society functional class IV (OR = 1.5), hypertension (OR = 1.4), and low ejection fraction (OR = 0.98) to be significant independent predictors of in-hospital mortality of octogenarians. Discharge to home rates were significantly lower for octogenarians. Conclusions Although early outcomes in octogenarians are acceptable, these factors alone are not sufficient to reflect overall success of CABG in these patients, given the strikingly lower discharge to home rates. Attention to full functional recovery in octogenarians is essential.

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). Results Twenty-three patients underwent repair. Median age was 15 days (range 2-1154 days). Patients were followed up for 5.3 ± 3.9 years. Seventeen (85%) required preoperative ventilatory assistance. One patient died within 24 hours; 1 patient died 8 months postoperatively. Four patients received valved homografts, and the remainder had valveless connections. All patients underwent reduction pulmonary arterioplasty and mobilization, unifocalization (in 3), and ventricular septal defect closure. Valveless connection recipients had a transannular hood. No patient underwent a Lecompte maneuver. Four patients underwent reoperation for conversion to valveless connection (n = 1), reduction arterioplasty (n = 1), and repair of pulmonary stenosis (n = 2). Three patients required catheter-based intervention, with balloon angioplasty (n = 3) and stent placement (n = 1); 2 now demonstrate equal quantitative lung perfusion. No patient has had significant debility from airway compromise. All patients demonstrate free pulmonary insufficiency and good biventricular function. Conclusions We report excellent overall survival (89%) and low postoperative morbidity for neonates and infants undergoing primary repair of tetralogy of Fallot with absent pulmonary valve syndrome. Our recent experience supports the use of a valveless right ventricle–pulmonary artery connection, which, combined with catheter-based intervention, reduces the likelihood of reoperation necessitated by homograft placement.

ObjectiveThe 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.MethodsTwo hundred one patients received HeartMate left ventricular assist devices (Thoratec Corp, Pleasanton, Calif) from January 1, 1996, to April 30, 2004. Of these, 119 (59.2%) had chronic congestive heart failure (diagnosis >6 months) as the primary indication. Outcome parameters included early mortality after left ventricular assist device placement (

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. Five (9.1%) patients died. Valved homograft recipients were more likely to require reoperation than patients receiving direct connections (40% vs 15%, P = .046); however, valved homograft and direct connection recipients had a similar incidence of the combined end point of reoperation or catheter-based intervention (40.0% vs 37.5%, P = .865). Univariate and multivariable modeling demonstrated use of valved homografts or direct connections with an autologous pericardial hood to be predictive of the need for later catheter-based intervention or reoperation. Actuarial analysis demonstrated a trend toward improved outcomes in the direct connection group and within the direct connection cohort, a statistically significant difference on the basis of hood type. Conclusions Although the direct connection technique might not prevent later catheter-based intervention, it does reduce the need for reoperation. Outcomes among direct connection recipients were associated with hood type: polytetrafluoroethylene hoods (W. L. Gore & Associates, Inc, Tempe, Ariz) had the lowest rate of reintervention, and untreated autologous pericardial hoods had the highest rate of reintervention. We report excellent outcomes with primary repair of truncus arteriosus. Where anatomically appropriate, we advocate the direct connection technique.

Background— Patients with low ejection fraction (EF) are at a higher risk for postoperative complications and mortality. Our objective was to assess the effect of low EF on clinical outcomes after coronary artery bypass grafting (CABG). Methods and Results— We analyzed 55,515 patients from New York State database who underwent CABG between 1997 and 1999. Patients were stratified into 1 of the 4 EF groups: Group I (EF≤20%), Group II (EF 21% to 30%), Group III (EF 31% to 40%), and Group IV (EF>40%). History of previous myocardial infarction, renal failure, and congestive heart failure were higher in patients with low EF (all P P P Conclusions— Patients with low EF are sicker at baseline and have >4 times higher mortality than patients with high EF. However, outcomes are improving over time and are superior to historical data. Therefore, CABG remains a viable option in selected patients with low EF.

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. Donor and recipient demographic and intraoperative and postoperative variables were acquired and correlated with perioperative (30-day) and late mortality in both univariate and multivariate analyses, and with Kaplan-Meier survival estimates. Results One hundred and six patients underwent transplantation for complex congenital heart disease and were followed for a median of 56 months. Thirty-seven (34.9%) patients died. Male gender and later year of transplantation were protective, and neonatal age and pulmonary artery reconstruction detrimental in multivariable modeling of overall mortality. Transplantation to a physiologic or anatomic single lung did not impact on survival. Patients in the study cohort had comparable survival estimates when compared with all those in the entire cohort without complex congenital heart disease. When comparing patients by era of transplantation, both cohorts demonstrated improved survival with later transplantation. Conclusions Outcomes with transplantation for complex congenital heart disease have improved annually over the past twenty years. Transplantation to an anatomic or physiologic single lung did not impair overall survival. Pulmonary artery reconstruction imparted an increase in mortality both short and long term, a finding which merits further investigation.
