Early and Late Outcomes of Multiple Coronary Endarterectomy

JOURNAL OF CARDIAC SURGERY, Issue 6 2008
Minoru Tabata M.D.
However, outcomes of multiple coronary endarterectomy (MCE) have not been well investigated. We sought to examine early and late results of this technique. Methods: Between January 1992 and June 2006, 58 consecutive patients underwent coronary endarterectomy in more than one coronary artery territories, representing 6.5% of total coronary endarterectomy during the same period. Early and late outcomes were retrospectively analyzed. Results: The mean age was 64 years. Forty-one patients (70.7%) had coronary endarterectomy in the left anterior descending artery and right coronary artery territories; five (8.6%) in the left anterior descending artery and circumflex artery territories; eight (13.8%) in the circumflex artery and right coronary artery territories; and four (6.9%) in the left anterior descending artery, circumflex artery, and right coronary artery territories. Operative mortality was 12.1% (7/58). The incidence of perioperative myocardial infarction was 25.9% (15/58). The median length of hospital stay was seven days. Actuarial five- and 10-year survivals were 64% and 36%, respectively. Conclusions: MCE may be a reasonable option for revascularization of multiple diffuse coronary artery disease. However, early and late outcomes are relatively poor and the indication should be carefully considered. [source]

Immediate and Late Outcomes of Transarterial Coil Occlusion of Patent Ductus Arteriosus in Dogs

JOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 1 2006
F.E. Campbell
Records from dogs (n = 125) that underwent attempted transarterial coil occlusion of patent ductus arteriosus (PDA) at the University of California, Davis, between 1998 and 2003, were reviewed, and a subset of these dogs (n = 31) in which the procedure was performed at least 12 months earlier were reexamined to determine long-term outcome. Coil implantation was achieved in 108 dogs (86%). Despite immediate complete ductal closure in only 34% of dogs, the procedure was hemodynamically successful as evidenced by a reduction in indexed left ventricular internal diameter in diastole (LVIDd; P < .0001), fractional shortening (P < .0001), and left atrial to aortic ratio (LA: Ao; P = .022) within 24 hours. Complete ductal closure was documented in 61% of dogs examined 12 to 63 months after coil occlusion. Long-standing residual ductal flow in the other 39% of dogs was not associated with increased indexed LVIDd or LA: Ao and was not hemodynamically relevant. Repeat intervention was deemed advisable in only 4 dogs with persistent (n = 1) or recurrent (n = 3) ductal flow. Complications included aberrant embolization (n = 27), death (n = 3), ductal reopening (n = 3), transient hemoglobinuria (n = 2), hemorrhage (n = 1), aberrant coil placement (n = 1), pulmonary hypertension (n = 1), and skin abscessation (n = 1). Serious infectious complications did not occur despite antibiotic administration to only 40% of these dogs. Transarterial coil occlusion was not possible in 14 dogs (11%) because of coil instability in the PDA and was associated with increased indexed minimum ductal diameter (P= .03), LVIDd (P= .0002), LVIDs (P= 0.001), and congestive left heart failure (P= .03) reflecting a relatively large shunt volume.

Late outcomes of drug-eluting versus bare metal stents in saphenous vein grafts: Propensity score analysis

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 1 2008
Robert J. Applegate MD
Abstract Objective: To compare late outcomes with the routine use of drug-eluting stents (DES) compared with bare-metal stents (BMS) during percutaneous intervention (PCI) of saphenous vein grafts (SVGs). Background: Safety concerns >1 year from stent implantation have been raised about DES used for PCI of SVGs in a small randomized clinical trial. However, there are few studies comparing late outcomes of DES and BMS in routine clinical practice. Methods: Clinical outcomes (nonfatal MI, cardiac mortality) were assessed in 74 consecutive patients who received BMS and 74 consecutive propensity score matched patients that received DES for PCI of SVGs. Clinical follow-up was censored at 2 years ± 30 days for both stent groups. Results: At 2 years, the hazard ratio for DES compared with BMS for PCI of SVGs for target vessel revascularization was 0.54 (0.21,1.36), nonfatal MI or cardiac death was 0.68 (0.27,1.68), cardiac mortality 1.19 (0.32,4.45), and stent thrombosis 0.49 (0.09,2.66). Similar outcomes were observed stratified by propensity score quintile. Conclusions: The routine clinical use of DES for PCI of SVGs was associated with a safety profile that was similar to that of bare metal stents with a clear trend toward a less frequent need for reinterventions. © 2008 Wiley-Liss, Inc.

Early and Late Results of Partial Left Ventriculectomy: Single Center Experience and Review of the Literature

JOURNAL OF CARDIAC SURGERY, Issue 3 2003
Raimondo Ascione M.D.
Methods: From February 1996 to August 2001, 24 patients with dilated cardiomyopathy (DCM) (12 idiopathic, 12 ischemic) underwent PLV. Perioperative and follow-up data were prospectively entered into a database and analyzed. An observational analysis of the literature was carried out of all the published series of PLV reporting on ,15 patients. Results: In our series there were 22 males with amean age of 65 years (range 49 to73]). Of the 22, there were 3 (12.5%) in-hospital deaths. Mean duration of follow-up was 26 months (range 3 to 71) with 9 late deaths (38%), 6 in the idiopathic group. The five-year actuarial survival was 74% in the ischemic group and 33% in the idiopathic group. The observational analysis of literature included a total of 506 patients (425 males, age 50.2 ± 5.2 years)]. The etiology was idiopathic in 255 (50.4%), and ischemic in 89 (17.6%) patients. Baseline characteristics of the whole population include: ejection fraction 18.9 ± 3.9%, NYHA functional class 3.7 ± 0.2, and LVEDD of 7.7 ± 0.4 cm. Severe mitral regurgitation was present in 368 (72.7%) patients. There were 88 (17.4%) in-hospital deaths. Cause of death included 55 due to (62.5%) low cardiac output, 10 (11.3%) due to severe bleeding, 7 (7.95%) caused by malignant arrhythmias, 8 (9%) due to sepsis, and 5 (5.7%) as a result of stroke. Ten of the selected series (overall 386 patients) reported late outcome. There were 89 (22.9%) late deaths, 12 (13.5%) were not cardiac-related, 50 (56.2%) were due to recurrence of congestive heart failure (CHF), 20 (22.5%) caused by sudden arrhythmias, 5 (5.6%) due to infections, and 2 (2.2%) from strokes. Overall, there were 248 (64.2%) survivors, of whom 179 (72.17%) were reported to be in NYHA functional class I or II. All 10 papers reported one-year survival ranging from 50% to 85%. Seven reported a two-year survival of 45% to 72%, and 4 reported a three-year survival of 33% to 64%. Conclusions: Our results and the review of the literature seem to suggest a relatively high early mortality with satisfactory late results of PLV in patients with dilated cardiomyopathy.(J Card Surg 2003;18:190-196) [source]

Mitral Regurgitation After Partial Left Ventriculectomy As the Cause of Ventricular Redilatation

JOURNAL OF CARDIAC SURGERY, Issue 2 2001
Akira T. Kawaguchi M.D.
Background: It remains unclear whether ventricular redilatation after partial left ventriculectomy (PLV) is due to underlying pathology or to continued volume overload amenable to surgery. Methods: Among patients undergoing PLV, 32 had Doppler echocardiography preoperatively, immediately after surgery (> 1 week), early after surgery (1,3 months), and late after surgery (8,14 months). Patients were divided into groups with mitral regurgitation (MR; MR+, n = 16) and without postoperative MR (MR-, n = 16) and were compared for ventricular size, performance, and survival. Results: After initial surgical reduction, left ventricular dimension on average gradually increased back to the preoperative level in subgroups of patients with valvular disease and cardiomyopathy and in all patients combined. Most patients showed drastically reduced left ventricular dimension early after PLV. In MR+ patients, dimension increased back to the preoperative level within 3 months after surgery, whereas the MR- group maintained reduced dimension throughout the first year in all patients combined and in a subgroup of patients with cardiomyopathy. Occurrence of significant MR after PLV appeared to be related to severity of fibrosis in excised myocardium but not to severity of preexisting MR, etiology, or performance of mitral valvuloplasty. Conclusions: Early postoperative MR, residual or new, appeared to play an important role in dictating early hemodynamics and late outcome in patients undergoing PLV. Results suggest an aggressive simultaneous approach to abolish MR. Causative role of myocardial fibrosis remains unclear and needs further study. [source]

Early and late outcome of cardiac surgery in patients with liver cirrhosis

LIVER TRANSPLANTATION, Issue 7 2007
Farzan Filsoufi
Liver cirrhosis is a major risk factor in general surgery. Few studies have reported on the outcome of cardiac surgery in these patients. Herein we report our recent experience in this high-risk patient population according to the Child-Turcotte-Pugh classification and Model for End-Stage Liver Disease (MELD) score. Between January 1998 and December 2004, 27 patients (mean age 58 ± 10 yr, 20 male) with cirrhosis who underwent cardiac surgery were identified. Patients were in Child-Turcotte-Pugh class A (n = 10), B (n = 11), and C (n = 6) and mean MELD score was 14.2 ± 4.2. Operative mortality was 26% (n = 7). Stratified mortality according to Child-Turcotte-Pugh class was 11%, 18%, and 67% for class A, B, and C, respectively. No mortality occurred in patients who had revascularization without the use of cardiopulmonary bypass (n = 5). The 1-yr survival was 80%, 45%, and 16% for Child-Turcotte-Pugh class A, B, and C, respectively (P = 0.02). Major postoperative complications occurred in 22%, 56%, and 100% for Child-Turcotte-Pugh class A, B, and C, respectively. Child-Turcotte-Pugh classification was a better predictor of hospital mortality (P = 0.02) compared to MELD score (P = 0.065). In conclusion, our results suggest that cardiac surgery can be performed safely in patients with Child-Turcotte-Pugh class A and selected patients with class B. Operative mortality remains high in class C patients. Careful patient selection is critical in order to improve surgical outcome in patients with cirrhosis. Liver Transpl, 2007. © 2007 AASLD.

Radical prostatectomy in obese patients: Improved surgical outcomes in recent years

INTERNATIONAL JOURNAL OF UROLOGY, Issue 8 2010
Uri Lindner
Objectives: Obesity has been proposed as a risk factor for reduced disease-specific survival, increased positive surgical margin (PSM) and biochemical recurrence (BCR) after radical prostatectomy (RP) in patients with prostate cancer. The aim of this study was to clarify the relationship between obesity and surgical outcomes in patients undergoing RP. Methods: Medical records of 491 patients who underwent RP from 2004 to 2007 were retrieved from our institutional database. Patients were divided into three groups based on their body mass index (BMI): <25, 25,30 (overweight) and >30 kg/m (obese). Outcomes after RP were compared between the groups in terms of length of stay, perioperative complications, BCR, PSM and Gleason scores. Results: Age, stage and preoperative prostate-specific antigen were similar between BMI categories. Operating time was prolonged in obese patients (146 vs 135 min, P = 0.01) and blood loss was greater (mean estimated blood loss 640 vs 504 mL, P = 0.02), but did not translate into higher transfusion rates. Early complication rates, PSM rates and Gleason scores were not statistically different between the groups. Significant differences in late outcomes, such as the need for adjunct procedures or BCR (hazard ratio 0.44, 95% CI 0.18,1.09), were not shown. Conclusion: As surgical experience with high BMI patients has developed, RP appears to be a well tolerated procedure in contemporary series, irrespective of BMI. In particular, early outcome parameters, such as PSM and BCR rates, are similar. [source]

Early and Late Outcomes of Multiple Coronary Endarterectomy

Drug-Eluting Stents Versus Bare Metal Stents Following Rotational Atherectomy for Heavily Calcified Coronary Lesions: Late Angiographic and Clinical Follow-Up Results

JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 2 2007
AHMED A. KHATTAB M.D.
Objectives: To study the effectiveness of drug-eluting stents following rotablation of severely calcified lesions. Background: Drug-eluting stents are increasingly showing promising results in complex lesions and high-risk patients. Heavily calcified stenoses have not been adequately studied, and form a challenge both for the immediate and late outcomes. Methods: Single-center prospective study among 27 patients treated by rotablation followed by a drug-eluting stent implantation for angiographically heavily calcified lesions, compared with a historical control of 34 patients treated by rotablation followed by bare stent implantation for the same indication. The primary endpoint was the late lumen loss at 9 months; secondary endpoints were binary restenosis and major adverse cardiac events at 9 months. A 2-year follow-up directed to death and myocardial infarction was added. Results: Both groups were comparable regarding baseline and procedural characteristics. Angiographic success was 100% for both groups. At 9 months, there was a significant difference in the late lumen loss (0.11 ± 0.7 mm in the DES group and 1.11 ± 0.9 mm in the BMS group, P = 0.001). This difference was manifest in the clinical event rates at late follow-up (combined incidence of death due to any cause, MI, and TLR was 7.4% in the DES group and 38.2% in the BMS group; P = 0.004). At 2 years, there were 5 deaths in each group (P = 0.5) and 2 infarctions in the BMS group versus none in the DES group (P = 1.0). Conclusion: The combination of rotablation and drug-eluting stent implantation (Rota-DES) has a favorable effect on clinical and angiographic outcomes at 9 months when treating heavily calcified lesions compared to rotablation followed by bare metal stent implantation. No safety concerns are observed at 2 years. [source]

Twenty years of follow-up among survivors of childhood and young adult acute myeloid leukemia,

CANCER, Issue 9 2008
A report from the Childhood Cancer Survivor Study
Abstract BACKGROUND Limited data exist on the comprehensive assessment of late medical and social effects experienced by survivors of childhood and young adult acute myeloid leukemia (AML). METHODS This analysis included 272 5-year AML survivors who participated in the Childhood Cancer Survivor Study (CCSS). All patients were diagnosed at age ,21 years between the years 1970 and 1986, and none underwent stem cell transplantation. Rates of survival, relapse, and late outcomes were analyzed. RESULTS The average follow-up was 20.5 years (range, 5,33 years). The overall survival rate was 97% at 10 years (95% confidence interval [95%CI], 94%,98%) and 94% at 20 years (95% CI, 90%,96%). Six survivors reported 8 recurrences. The cumulative incidence of recurrent AML was 6.6% at 10 years (95% CI, 3.7%,9.6%) and 8.6% at 20 years (95% CI, 5.1%,12.1%). Ten subsequent malignant neoplasms (SMN) were reported, including 4 with a history of radiation therapy, for a 20-year cumulative incidence of 1.7% (95% CI, 0.02%,3.4%). Six cardiac events were reported, for a 20-year cumulative incidence 4.7% (95% CI, 2.1%,7.3%). Half of the survivors reported a chronic medical condition and, compared with siblings, were at increased risk for severe or life-threatening chronic medical conditions (16% vs 5.8%; P < .001). Among those aged ,25 years, the age-adjusted marriage rates were similar among survivors and the general United States population (57% for both) and lower compared with siblings (67%; P < .01). Survivors' college graduation rates were lower compared with siblings but higher than the general population (40% vs 52% vs 34%, respectively; P < .01). Employment rates were similar between survivors, siblings, and the general population (93%, 97.6%, and 95.8%, respectively). CONCLUSIONS Long-term survival from childhood AML ,5-years after diagnosis was favorable. Late-occurring medical events remained a concern with socioeconomic achievement lower than expected within the individual family unit, although it was not different from the general United States population.
