Measurement of Adhesion of Sternal Wires to a Novel Bioactive Glass-Based Adhesive. J Funct Biomater 2019; 10:jfb10030037. [PMID: 31405006 PMCID: PMC6787671 DOI: 10.3390/jfb10030037] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2019] [Revised: 07/29/2019] [Accepted: 08/05/2019] [Indexed: 11/17/2022] Open
Abstract
Stainless steel wires are the standard method for sternal closure because of their strength and rigidity, the simplicity of the process, and the short healing time that results from their application. Despite this, problems still exist with sternal stability due to micromotion between the two halves of the dissected and wired sternum. Recently, a novel glass-based adhesive was developed which, in cadaveric trials and in conjunction with wiring, was shown to restrict this micromotion. However, in order to avoid complications during resternotomy, the adhesive should adhere only to the bone and not the sternal wire. In this study, sternal wires were embedded in 8 mm discs manufactured from the novel glass-based adhesive and the constructs were then incubated at 37 °C for one, seven, and 30 days. The discs were manufactured in two different thicknesses: 2 and 3 mm. Wire pull-out tests were then performed on the constructs at three different strain rates (1, 0.1, and 0.01 mm/min). No statistically significant difference in pull-out force was found regardless of incubation time, loading rate, or construct thickness. The pull-out forces recorded were consistent with static friction between the wire and adhesive, rather than the adhesion between them. Scanning electron micrographs provided further proof of this. These results indicate that the novel adhesive may be suitable for sternal fixation without complicating a potential resternotomy.

Postoperative acute kidney injury defined by RIFLE criteria predicts early health outcome and long-term survival in patients undergoing redo coronary artery bypass graft surgery. J Thorac Cardiovasc Surg 2016; 152:235-42. [PMID: 27016793 PMCID: PMC4915911 DOI: 10.1016/j.jtcvs.2016.02.047] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2015] [Revised: 01/28/2016] [Accepted: 02/19/2016] [Indexed: 11/23/2022]
Abstract
Objective To investigate the impact of postoperative acute kidney injury (AKI) on early health outcome and on long-term survival in patients undergoing redo coronary artery bypass grafting (CABG). Methods We performed a Cox analysis with 398 consecutive patients undergoing redo CABG over a median follow-up of 7 years (interquartile range, 4-12.2 years). Renal function was assessed using baseline and peak postoperative levels of serum creatinine. AKI was defined according to the risk, injury, failure, loss, and end-stage (RIFLE) criteria. Health outcome measures included the rate of in-hospital AKI and all-cause 30-day and long-term mortality, using data from the United Kingdom's Office of National Statistics. Propensity score matching, as well as logistic regression analyses, were used. The impact of postoperative AKI at different time points was related to survival. Results In patients with redo CABG, the occurrence of postoperative AKI was associated with in-hospital mortality (odds ratio [OR], 3.74; 95% confidence interval [CI], −1.3 to 10.5; P < .01], high Euroscore (OR, 1.27; 95% CI, 1.07-1.52; P < .01), use of IABP (OR, 6.9; 95% CI, 2.24-20.3; P < .01), and reduced long-term survival (hazard ratio [HR], 2.42; 95% CI, 1.63-3.6; P = .01). Overall survival at 5 and 10 years was lower in AKI patients with AKI compared with those without AKI (64% vs 85% at 5 years; 51% vs 68% at 10 years). On 1:1 propensity score matching analysis, postoperative AKI was independently associated with reduced long term survival (HR, 2.8; 95% CI, 1.15-6.7). Conclusions In patients undergoing redo CABG, the occurrence of postoperative AKI is associated with increased 30-day mortality and major complications and with reduced long-term survival.

Abstract
BACKGROUND The number of patients undergoing resternotomy continues to rise. Although catastrophic hemorrhage remains a dreaded complication, most published data suggest that sternal reentrance is safe, with negligible postoperative morbidity and mortality. A significant proportion of left ventricular assist device (LVAD) implantations are reoperative cardiac procedures. The aim of our study was to compare outcomes between first time sternotomy and resternotomy patients receiving continuous-flow LVADs, as a bridge to transplantation or destination therapy. METHODS AND MATERIALS From March 2006 through February 2012, 100 patients underwent implantation of a HeartMate II or HeartWare LVAD at our institution. Patients were stratified into two groups, primary sternotomy and resternotomy. Variables were compared using two-sided t-tests, chi-square tests, Cox proportional hazards models, and log-rank tests to determine whether there was a difference between the two groups and if resternotomy was a significant independent predictor of outcome. RESULTS We identified 29 patients (29%) who had resternotomy and 71 patients (71%) who had first time sternotomy. The resternotomy group was significantly older (56 years vs. 51 years, p = 0.05), was more likely to have ischemic cardiomyopathy (ICM) (69% vs. 30%, p < 0.001), chronic obstructive pulmonary disease (COPD) (31% vs. 14%, p = 0.05) and had longer cardiopulmonary bypass times (135 min vs. 100 min, p = 0.011). Survival rates at 30 days (93.1% vs. 95.8%, p = 0.564), 180 days (82.8% vs. 93%, p = 0.131), and 360 days (82.8% vs. 88.7%, p = 0.398) were similar for the resternotomy and primary sternotomy groups, respectively. Postoperative complications were also comparable, except for re-exploration for bleeding which was higher for the resternotomy group (17.2% vs. 4.2%, p = 0.029), although blood transfusion requirements were not significantly different (1.4 units vs. 1.2 units, p = 0.815). Left and right heart catheterization measurements and echocardiographic (ECHO) findings after 1 and 6 months of LVAD therapy were similar between the two groups. CONCLUSIONS Survival at 30, 180, and 360 days after LVAD implantation is similar between the resternotomy and primary sternotomy group. No major differences in complications or hemodynamic measurements were observed. Although a limited observational study, our findings agree with previously published resternotomy outcomes.

Abstract
Multiple factors contribute to the growing number of reoperations for congenital and acquired cardiovascular diseases in the United States. Although the hazards are well-recognized, the health economic burden of resternotomy (RS) remains unclear and may be difficult to quantify. Contrary to published studies citing low frequencies of catastrophic hemorrhage and mortality, survey responses from practicing surgeons disclose higher rates of complications. Safety strategies in cardiac reoperation have generally involved efforts to maximize visualization during dissection, specialized surgical maneuvers and instrumentation, customized methods for establishing extracorporeal circulation, and techniques to prevent or avoid retrosternal adhesions. Yet, the relative cost-effectiveness of these strategies is largely unexplored. With the ongoing constraints in healthcare budgets, differentiating the value of existing and future approaches in terms of relative clinical benefits, costs, and impact on resource utilization will become increasingly important. We reviewed the relevant published literature in order to survey the morbidity and resource utilization associated with RS in cardiac reoperation and to identify key issues relevant for future studies.

Abstract
OBJECTIVE We aimed to investigate the risk factors for hospital mortality, short (five years) and mid-term (10 years) survival in patients who underwent mitral valve replacements in redo patients with previous mitral valve procedures. PATIENTS AND METHODS Between September 1989 and December 2003, 62 redo patients have undergone mitral valve replacements due to subsequent mitral valve problems. Preoperative, operative, and postoperative data were analyzed retrospectively and evaluated for risk factors affecting hospital mortality, mid- and long-term survival. RESULTS The hospital mortality was 6.4%. The one-, five-, and 10-year actuarial survival rates were 94%+/- 2%, 89%+/- 6%, and 81 +/- 9%. New York Heart Association (NYHA) functional class IV, low left ventricular ejection fraction (<35%), increased left ventricular end-diastolic diameter (LVEDD) > 50 mm, female gender, pulmonary edema, and urgent operations were found to be risk factors in short-term survival. NYHA functional class IV, low left ventricular ejection fraction, increased LVEDD, and increased left atrial diameter (LA > 60 mm) were risk factors in mid-term survival. CONCLUSION Redo mitral valve surgery with mechanical prosthesis offers encouraging short- and mid-term survival. NYHA functional class IV, low left ventricular ejection fraction, and increased left ventricular diameters were especially associated with increased short- and mid-term mortality. Earlier surgical management before the development of severe heart failure and myocardial dysfunction would improve the results of redo mitral valve surgery.

Abstract
BACKGROUND Intraoperative and postoperative bleeding and injuries to cardiac structures are among the main determinants of complications and hospital and intensive care unit stay after cardiac reinterventions. The harmonic scalpel has been reported to achieve optimal tissue dissection with little blood loss. The present retrospective work was performed to evaluate the safety and usefulness of this device in redo cardiac surgery. METHODS Ninety-six redo cardiac surgery patients were operated on with the use of harmonic scalpel, and 105 redo patients operated on by traditional electrocautery and scissors were selected from our database and served as controls. Intraoperative and postoperative data of the two groups were collected and compared. Univariate and multiple logistic regression analyses were performed for identification of factors associated with death and with major and minor complications in the overall study population and in both groups, separately. RESULTS Although mortality and major postoperative morbidity were comparable in the two groups, harmonic scalpel patients presented markedly reduced postoperative bleeding, lower incidence of minor complications, cardiac injuries, major arrhythmias, and need for transfusions. Operative time and mean intensive care unit stay were shorter. Use of ultrascissor was found to be a protective factor against minor morbidity at multivariate analysis. CONCLUSIONS Our data suggest that harmonic scalpel is safe and is associated with better in-hospital outcome and lower postoperative blood loss in redo cardiac surgery.

Abstract
BACKGROUND Reoperative (redo) mitral valve surgery is still a continuing challenge to surgeons. The aim of this study was to detect the factors that affect late mortality or morbidity after redo mitral valve surgery in patients with rheumatic disease. METHODS Between May 1983 and February 2003, 92 patients who underwent redo mitral valve surgery for rheumatic disease were enrolled. Risk factors influencing survival or cardiac events were investigated with univariate analysis and a Cox model. RESULTS Operative mortality rate was 4.2%. Kaplan-Meier actuarial analysis demonstrated an 84.7% 5-year, a 69.5% 10-year, and a 65.9% 15-year survival. Multivariate analysis demonstrated that age at surgery and preoperative New York Heart Association (NYHA) class were found to be independent predictors of late deaths, and that higher age, advanced NYHA class, and previous mitral valve replacement were independent predictors of cardiac events. CONCLUSIONS Redo mitral valve surgery can be achieved with low early mortality. However, long-term results of redo mitral surgery are not necessarily satisfactory in patients with preoperative advanced NYHA class or with a previous mechanical heart valve, and especially in 60 years or older age.

Abstract
BACKGROUND The octogenarian patient is often perceived as too fragile to undergo cardiothoracic surgery. Our study aimed to compare postoperative complications in patients aged less than 80 versus elderly patients (80 years or more) after surgical cardiac intervention (coronary artery bypass or valve replacement). METHODS Subjects were all patients (n = 8,361) who had an open-heart procedure, either coronary artery bypass or valve implantation or replacement, at two medical centers located in northern Virginia using the same surgical group. A computerized medical record database was reviewed to determine preoperative risk factors and postoperative outcomes. Predictors of complications were identified by univariate and multivariate logistic regression. RESULTS A total of 3,214 complications were recorded. The most prevalent complications were prolonged ventilation time in the intensive care unit, reoperation for bleeding, and pneumonia. The overall mortality rate was 2.4% (204 of 8,361). Persons aged over 80 years had nearly double the mortality rate compared with younger patients (4.1% [18 of 444] to 2.3% [186 of 7,917]). Age greater than 80 years (odds ratio = 2.65, 95% confidence interval = 2.18 to 3.22) and male gender (odds ratio = 0.62, 95% confidence interval = 0.56 to 0.69) were the best univariate predictors of a single postoperative complication. CONCLUSIONS Octogenarian patients manifested twice the risk of death from a cardiac intervention with an average 2-day longer hospital stay compared with their younger counterparts. Furthermore, octogenarians were at markedly higher risk of nonfatal postoperative complications.

Abstract
BACKGROUND We compared our experience of minimal tissue dissection and target vessel revascularization without cardiopulmonary bypass (CPB) with the standard procedure of total dissection of the heart and complete revascularization with CPB in patients who had elective reoperative coronary artery bypass grafting (redo-CABG). METHODS We analyzed recurrence of angina and clinical outcome in 118 patients who had elective redo-CABG between January 1995 and April 2002. Seventy-four patients had redo-CABG with CPB, and 44 patients had redo-CABG without CPB. RESULTS Perioperative outcome was comparable with regard to morbidity and mortality rates. At follow-up, the mean Canadian Cardiovascular Society score was 1.3 +/- 0.6 in patients who had redo-CABG with CPB and 1.7 +/- 0.8 in patients who had redo-CABG without CPB (p = 0.02). At follow-up, patients who had redo-CABG without CPB had a higher rate of recurrence of angina (log rank = 0.001) and higher use of nitrates (p = 0.015). Target vessel revascularization was an independent predictor of recurrence of angina in younger patients (< 75 years; p = 0.012) but not in the elderly (> or = 75 years; p = 0.142). CONCLUSIONS In elective redo-CABG patients, minimal tissue dissection and target vessel revascularization without cardiopulmonary bypass did not add significant benefit with regard to perioperative morbidity and mortality. The unsatisfactory relief of symptoms does not seem to justify target vessel revascularization by a less invasive approach. Therefore, this technique should be offered exclusively to patients at high risk with complete revascularization using CPB, such as the elderly.

Abstract
OBJECTIVE In recent years, satisfactory outcome of primary cardiac operation in octogenerians and increased ageing of cardiac surgical population in western hospitals have led to increased expectations and referrals for reoperation. Outcome of reoperation in this aged subset was analysed. METHODS Consecutive 18 octogenerians (mean age 81.2 years, 10 men, eight women) undergoing cardiac reoperations from November 1989 through August 1998 were retrospectively reviewed. RESULTS They represented 6.2% of all octogenerian cardiac surgical patients and 2.7% of all reoperations during the same period. Mean preoperative NYHA class was 3.4 and Parsonnet score was 29.4. The interval to reoperation was 114.5+/-11.96 (4-188) months. Priority was urgent in 11 and elective in seven patients. The procedures included four AVRs, five MVRs (including two associated TVAs), six CABGs and one each of MVR with CABG, AVR with CABG and AVR, MVR and CABG. Average graft/patient was 2.3. Mean ICU stay was 4.6+/-1.5 (1-28) days. There was one hospital death (5.5%) on 18 pod after MVR in an 83-year-old woman. Mean postoperative stay was 20.2+/-5.13 (8-93) days. There were three late deaths (17.6%)--at 32 months after MVR, at 44 and 63 months after CABG. Long-term survivors were 90% among men and 50% among women who were followed up for 42.7+/-6.9 (9-93) months. Mean Karnofsky score in survivors at 1 year of follow-up was 78.5+/-2.9. Despite continued medication in all survivors, mean current NYHA is 1.9 and most have improved lifestyle. CONCLUSIONS Satisfactory outcome may be expected after cardiac reoperations in highly selected octogenerians. However, increased procedural risks, complications, hospital stay and slower convalescence during early follow-up may be anticipated, and will indicate very careful screening. These results indicate a need to reconsider the treatment policy in primary operation with regard to choice of graft conduits and prosthetic valves in other elderly patients.

Abstract
BACKGROUND Coronary artery bypass grafting (CABG) reoperation is being performed with increasing frequency. OBJECTIVE To determine the clinical outcome and the long-term results of a second CABG. SETTING An 1100-bed urban university-affiliated hospital. DESIGN Retrieval of data on selected parameters from medical records before surgery and prospective follow-up afterwards. PATIENTS AND METHODS We studied the outcomes of 498 consecutive patients who underwent CABG reoperation in our institution from January 1978 to December 1989 and who were followed postoperatively. Their perioperative mortality, morbidity, and long-term follow-up results were re-evaluated. The end points of the study were December 1997, 15 years of follow-up, or the patient's death. RESULTS The perioperative mortality rate was 3%. The cumulative survival rates were 90.1%, 74%, and 63.4% at the 5-year, 10-year, and 15-year follow-ups, respectively. The cardiac event-free survival rates were 91.5%, 83.4%, and 67.8% at the 5-year, 10-year, and 15-year follow-ups, respectively. The risk factors adversely affecting long-term survival were advanced age, hypertension, and a low left ventricular ejection fraction (LVEF). CONCLUSIONS The long-term results of cumulative survival and cardiac event-free survival in patients who underwent CABG reoperation are good. Although this reoperation is safe overall, advanced age, hypertension, and a decreased LVEF significantly increase the surgical risk.
