Long Term Survivors

Since we started using ventricular assist devices (VAD) in July 1987 up to August 1993, 63 of 15,650 (0.4%) patients (pts) who underwent open heart sugery were supported postoperatively by VAD at out institution. Forty-three were male and 20 female, mean age 55.5 years. In 49 pts coronary artery bypass grafting (CABG), in 8 pts valve surgery, in 3 pts combined CABG and valve surgery and in 3 pts corrective procedures for congenital heart disease were performed. Perioperative myocardial infarction was the most frequent indication (73%). In 37 of the 63 pts (58.7%) a centrifugal (Biomedicus pump (group A) was used and in 26 pts (41.3%) a pulsatile Abiomed BVS 5000 (group B). Fourteen of 37 pts (38%) in group A were weaned from the VAD and all of them were discharged. Twenty-three pts were unable to be weaned and 19 of these pts died. The remaining 4 pts were transplanted successfully and subsequently 3 died and 1 was discharged. In all, 15 pts (39%) were long-term survivors. Sixteen of 26 pts (62%) in group B were weaned from VAD and 13 (50%) of them were discharged of whom 3 died. Ten patients were unable to be weaned and 7 of these died. The remaining 3 pts were transplanted successfully. In all, 16 pts (61.5%) were long-term survivors. The shorter the interval between beginning resuscitation and application of VAD the better the outcome. Younger age, VAD installation in OR, support time between 2 and 7 days and Abiomed pump, influence the survival rate positively. Because of higher recovery and survival rates in patients assisted by Abiomed compared to the Biomedicus pump, we recommend the Abiomed pump in postcardiotomy cardiac failure.

Abstract Background Mild preoperative renal dysfunction (RD) is not rare in patients receiving isolated cardiopulmonary coronary artery bypass grafting (CCABG). However, there are not too many studies about the impact of mild preoperative RD on in-hospital and follow-up outcomes after isolated CCABG. This single-centre, retrospective propensity score matching study designed to study the impact of mild preoperative RD on in-hospital and long-term outcomes after first isolated CCABG. Methods After propensity score matching, 1144 patients with preoperative estimated glomerular filtration rate (eGFR) of more than 60 ml/min/1.73 m2 receiving first isolated CCABG surgery from January 2012 to December 2015 entered the study, who were divided into 2 groups: A group (eGFR ≥90 ml/min/1.73 m2, n = 572) and B group (eGFR of 60–89 ml/min/1.73 m2, n = 572). The in-hospital and long-term outcomes were recorded and analyzed. The mean follow-up time was 54.4 ± 10.7 months. Acute kidney injury (AKI) was defined and classified according to the Acute Kidney Injury Network (AKIN) criteria. Results The 2 propensity score-matched groups had similar baseline and procedure except the baseline eGFR. There were 8 patients died in A group (mortality is 1.4%) and 14 died in B group (mortality is 2.5%) during the in hospital and 30-day postoperatively(χ2 = 1.159, p = 0.282). There were totally 38 patients lost to follow-up, 18 in group A and 20 in group B. 21 patients died in group A and 37 died in group B during the follow-up, and long-term survival in group A was higher than in group B (96.2% vs 93.1%, χ2 = 4.336, p = 0.037). Comparing with group A, group B was associated with an increased rates and severity of AKI postoperatively (total AKI: 62 vs 144. AKIN stageI: 54 vs 113; AKIN stageII: 6 vs 22; AKIN stageIII: 2 vs 9, p<0.0001). During follow-up, group B also had a higher rate of new onset of dialysis (0 vs 6, χ2 = 4.432, p = 0.039). Multivariable logistic regression showed that comparing with A group, the HR for long-term mortality and new onset of dialysis in B group was 1.67 and 1.52 respectively (95%CI 1.09–2.90, p = 0.035; 95%CI 1.14–2.49, p = 0.027). Conclusions Comparing with normal preoperative renal function, patients with mild preoperative RD had a similar in-hosptial mortality, but with an increased in-hosptial rates and severity of AKI, and with a decreased long-term survival and increased long-term new onset of dialysis.

Long Term Mortality

ObjectivesThis study sought to compare clinical outcomes between three categories of patients: non-chronic obstructive pulmonary disease (COPD), diagnosed COPD and undiagnosed COPD in coronary artery bypass grafting surgery.MethodsA single-centred retrospective study from January 2010 to December 2019. Primary outcomes were postoperative complications, length of ITU admission and in-hospital staying. Secondary outcomes were reintervention rate, in-hospital and long-term mortality.ResultsA total of 4020 patients were analysed and divided into three cohorts: non-COPD (group A) (74.55%, n=2997), diagnosed COPD (group B) (14.78%, n=594) and undiagnosed COPD (group C) (10.67%, n=429). The rate of respiratory complications was noted in this order: group B>group C>group A (p 0.00000002). Periooperative acute kidney injury and wound complications were higher in group B (p 0.0004 and p 0.03, respectively). Prolonged in-hospital staying (days) resulted in group B (p 0.0009). Finally, long-term mortality was statistically higher in group B and C compared with group A (p 0.0004). No difference in long-term mortality was noted in relation to the expected FEV1% in group B (p 0.29) and group C (p 0.82).ConclusionsIn CABG surgery, COPD is a well-known independent risk factor for morbidity. Patients with preoperative spirometry results indicative of COPD result in the same outcomes of known patients with COPD. As a result of that, greater value should be given to the preoperative spirometry in the EuroSCORE. Finally, the expected FEV1% appears not be a predictor for long-term survival.

Background— The purpose of this study was to evaluate mortality after coronary artery bypass grafting (CABG) comparing the use of only in situ arterial grafts with the use of arterial and venous conduits. Methods and Results— From April 1985 to March 1999, 1159 patients with multivessel disease underwent elective, isolated, primary, multiple CABG with at least one in situ arterial conduit. Patients who were on chronic dialysis, had active malignant disease, or had free arterial conduits were excluded. The long-term results were compared between 532 patients who had CABG using only in situ arterial conduits (group A; mean follow-up, 7.8 years) and 627 patients who underwent CABG using in situ arterial conduits and saphenous vein grafts (group B; mean follow-up, 10.3 years). Actuarial survival and freedom from cardiac death were determined by the Kaplan-Meier method. Propensity score was included in the Cox multivariable regression model for adjustment of selection bias. Survival at 10 years after surgery was 81.4% in group A and 76.9% in group B ( P =0.11). Freedom from cardiac death at 10 years was 93.4% in group A and 90.4% in group B. Hazard ratio for cardiac death was significantly lower in group A (0.61; 95% confidence interval, 0.38 to 1.00; P =0.05). Conclusions— Our data suggest that the exclusive use of in situ arterial grafts in CABG achieves significantly better long-term survival compared with combined use of arterial and vein grafts.

Introduction: Intravascular ventricular assist device (iVAS; NuPulse CV, North Carolina, USA) is a newly developed ambulatory and portable counter pulsation heart assist system. Hypothesis: Early and late clinical outcomes of iVAS is comparable to those of conventional axillary intra-aortic balloon pump (IABP) as a bridge to heart transplantation(BTT). Methods: Between April 2016 and January 2020, 33 patients underwent iVAS implantation (Group A) and 69 patients underwent axillary IABP (Group B) as a BTT. We reviewed perioperative data and late clinical outcomes including survival. Long-term survival was assessed with the Kaplan-Meier analysis. Results: The patients in Group A was significantly older than Group B (A: 58.8±8.1 vs B: 53.3±14.7 p=0.048). The use of inotropes at the time of device implantation was similar between two groups (A:22/33(66.7%) vs B: 47/69(68.1%), p=0.88). Almost all patients were able to ambulate and participate in physical therapy (A:100% vs B:97.1%, p=0.21). The duration of device support in Group A was significantly longer than Group B (A:83.3±93.7 vs B:19.0±13.3 days, p &lt;0.01). After a FDA approval, eleven patients (44%) in Group A was able to be discharged with an iVAS. While waiting for transplantation, 3 patients expired in Group A and none in Group B. Two patients in Group A required an escalation of support (ECMO N=1, LVAD N=1) and 1 patients in Group B (percutaneous LVAD N=1). Balloon exchange due to device related complications was required less frequently in Group A compared to Group B (A: 2/33, 6.1% vs B: 20/69, 29.0% p &lt;0.01). Adverse events during balloon exchange included aortic rupture (N=1) and type A aortic dissection (N=1) (all in Group B). The success rate of BTT was not significantly different between groups (A:27/32(84.4%), B: 64/68(94.1%),p=0.13). The long-term survival after heart transplantation did not differ between the groups (A: 78.1% at 3 years vs B: 83.8% at 3 years, log-rank=0.07). Conclusions: Both iVAS and conventional axillary IABP showed comparable long-term survival and decent success rates of BTT. The iVAS featured with the portable mechanism might be a promising option as a BTT.

Between January 1988 and January 1992, 65 patients (pts) had a ventricle assist device (VAD) inserted in our clinic. In 24 pts a VAD was applied because of primarily unsuccessful weaning from cardiopulmonary bypass (Group A). In a further 24 pts (Group B) a VAD was installed for the therapy of refractive cardiogenic shock (CS) after initially successful cardiac surgery (n=21) and after acute myocardial infarction (n=3). Twelve pts were bridged to heart transplantation (Group C) and five had a VAD inserted for various other reasons (Group D). In 36 (55.4%) of the total 65 pts a nonpulsatile VAD (Biomedicus® 540) was used: 10 in Group A; 20 in B, 3 in C and 3 in D. In 29 pts (44.6%) a pulsatile VAD (Abiomed® BVS 5000) was used: 14 in Group A, 4 in B, 9 in C and 2 in D. Weaning rate and long-term survival rates were 50% and 46% respectively in Group A and 38% and 42% in Group B. Seven pts from Group C were transplanted and six are long-term survivors. Two pts (40%) in Group D were discharged from hospital. Major postoperative complications were bleeding (46%), thromboembolism (14%), multiple organ failure (11%), renal failure (11%), arterial embolism (4.6%), sepsis (3%). The results indicate that application of a VAD can be recommended in pts with postcardiotomy CS to allow recovery of cardiac function and in pts with irreversible ventricular damage as bridging to HTX.

308 Background: Long-term survival in patients with advanced unresectable hepatocellular carcinoma (HCC) treated with drug-eluting bead transarterial chemoembolization (DEB-TACE) vs. best supportive care has not been investigated in large-scale population studies. Methods: Under IRB approval, our institute’s cancer registry was queried for patients with advanced unresectable HCC diagnosed from Sept 2005 to Dec 2010, treated with DEB-TACE. Eighteen registries of the U.S. Surveillance, Epidemiology and End Results (SEER) database were queried for patients with advanced HCC not amenable to surgery/radiation diagnosed in the same time period. Baseline characteristics, median overall survival (OS) from HCC diagnosis and median OS from first DEB-TACE were stratified by national/state cohorts. Survival analysis and 95% confidence intervals (CI) were calculated using Kaplan-Meier estimation. Results: A total of 231 patients who underwent DEB-TACE for unresectable HCC (Group A) and 20,897 patients with unresectable HCC who received neither radiation nor cancer-directed surgery (Group B) were included. Both groups were similar for mean age at diagnosis, gender, race, bilobar disease, portal vein thrombosis and mean largest tumor size (p>0.05). Median OS from HCC diagnosis was 21.8 months (Group A; 95% CI, 18.1-25.4) and 4.0 months (Group B; 95% CI, 3.9-4.1), p<0.001. Median OS from first DEB-TACE was 15.0 months (Group A; 95% CI, 9.6-20.4). Interval survival rates from HCC diagnosis for Group A vs. B were: 99% vs. 65% (1 month), 92% vs. 49% (3 months), 75% vs. 36% (6 months), 58% vs. 35% (1 year), 36% vs. 9% (2 years), and 20% vs. 4% (3 years). Conclusions: DEB-TACE in patients with unresectable HCC demonstrated significantly greater median OS and favorable long-term survival rates compared to best supportive care in a population-based study.

Background: Frozen shoulder is disorder of the connective tissue that limits the normal Range of motion of the shoulder in diabetes, frozen shoulder is thought to be caused by changes to the collagen in the shoulder joint as a result of long term Hypoglycemia. Mobilization is a therapeutic movement of the joint. The goal is to restore normal joint motion and rhythm. The use of mobilization with movement for peripheral joints was developed by mulligan. This technique combines a sustained application of manual technique “gliding” force to the joint with concurrent physiologic motion of joint, either actively or passively. This study aims to find out the effects of mobilization with movement and end range mobilization in frozen shoulder in Type I diabetics. Materials and Methods: 30 subjects both male and female, suffering with shoulder pain and clinically diagnosed with frozen shoulder was recruited for the study and divided into two groups with 15 patients each based on convenient sampling method. Group A patients received mobilization with movement and Group B patients received end range mobilization for three weeks. The outcome measurements were SPADI, Functional hand to back scale, abduction range of motion using goniometer and VAS. Results: The mean values of all parameters showed significant differences in group A as compared to group B in terms of decreased pain, increased abduction range and other outcome measures. Conclusion: Based on the results it has been concluded that treating the type 1 diabetic patient with frozen shoulder, mobilization with movement exercise shows better results than end range mobilization in reducing pain and increase functional activities and mobility in frozen shoulder.

Background: Laparoscopic Incisional and Ventral Hernia Repair (LIVHR) is a safe and worldwide accepted procedure performed using absorbable tacks. The aim of the study was to evaluate recurrence rate in a long term follow-up and whether the results of laparoscopic IVH repair in the elderly (≥65 years old) are different with respect to results obtained in younger patients. Methods: One hundred and twenty-nine consecutive patients (74 women and 55 men, median age 67 years, range = 30-87 years) with ventral (N = 42, 32.5%) or post incisional (N = 87, 67.5%) hernia were enrolled in the study. Patients were divided into two groups according to their age: group A (N = 55, 42.6%) aged <65 years and group B (N = 74, 57.4%) aged ≥65 years. Results: The mean operative time was not significantly different between groups (66.7 ± 37 vs. 74 ± 48.4 min, p = 0.4). To the end of 2016, seven recurrences had occurred (group A = 3, group B = 4, p = 1). Complications occurred in 8 (16%) patients in group A and 21 (28.3%) patients in group B. Conclusion: In conclusion, our results confirm that the use of absorbable tacks does not increase recurrence frequency and laparoscopic incisional and ventral repair is a safety procedure also in elderly patients.
