Concurrent implantation of intra-aortic balloon pumping with extracorporeal membrane oxygenation improved survival of patients with postcardiotomy cardiogenic shock

Background Extra-corporeal membranous oxygenation (ECMO)and intra-aortic balloon pumping (IABP) are widely used in patients with severe circulatory failure. The decision to initiate ECMO and IABP on optimal occasion in postcardiotomy cardiogenic shock (PCS) remains controversial in the absence of guidelines.

Thrombocytopenia in patients of acute coronary syndrome with intra-aortic balloon pumping placement

Background Thrombocytopenia is a common complication of IABP. Until now,there is no unified conclusions about the incidence,characteristics,risk factors and the prognosis of IABP related thrombocytopenia.Methods In this study,the data of patients with ACS undergoing PCI and IABP were retrospectively analyzed.All enrolled patients were divided into thrombocytopenia group and non-thrombocytopenia group according to the occurrence of thrombocytopenia after insertion of IABP. The baseline data of the two groups were compared,and the possible risk factors of thrombocytopenia and their impact on prognosis were analyzed by chi-square test and logistic regression analysis. Results Sixty-two patients were enrolled in this study. The rate ofIABP associated thrombocytopenia was 25.8%(16/62)of all patients. Older agewas an independent risk factor of IABP associated thrombocytopenia(OR:3.625;95% confidence interval:1.016-12.935;P=0.047). The incidence of TIMI bleeding events was higher in thrombocytopenia group[75.0%(12/16)vs. 43.5%(20/46),P=0.042]. The rate of in-hospital death was similar between the two groups[18.8%(3/16)vs. 17.4%(8/46),P=1.0]. Conclusion IABP associated thrombocytopenia occurs in 25.8% of patients with ACS undergoing PCI and correlates with increased TIMI bleeding events. Older age may predict IABP associated thrombocytopenia.

Clinical significance of intra-aortic balloon pumping on no-reflow phenomenon of primary percutaneous coronary intervention for acute myocardial infarction

Background Percutaneous coronary intervention （PCI） is used as a treatment for acute myocardial infarction （AMI）, and one of its major complications is the angiographic no-reflow phenomenon （NR）. Although intra-aortic balloon pumping （IABP） is sometimes used in such patients to increase the diastolic coronary blood flow, there is little available information regarding the effects of IABP on the angiographic no-reflow phenomenon. Method Twenty-two AMI patient with NR were performed primary PCI between January 2006 and December 2009, of which 12 patients were selected for IABP therapy and the left 10 were selected as the control group by group procedure of odd and even days; We observed the vasoactive substance in both groups on the days of 1, 2, 3, 5, 7, 10 after the different interventions, which include plasma renin activity （PRA）, angiotensin Ⅱ （ANG Ⅱ）, aldosterone （ALD）, adrenaline （E）, and noradrenalin （NE）; In addition, cardiac structure and cardiac ventricle systolic function including left atrium medial diameter （LAMD）, left ventricular medial diameter （LVMD） Finally, left ventricular ejection fraction （LVEF） were evaluated after 10 days, 3 months and 6 months; statistics was taken to analysis. Results According to the time concentration curve, vasoactive substance of the IABP group decreased faster than that of the control group, and this difference had statistical significance （P 〈 0.01 ） ; In terms of LAMD, LVMD, and LVEF, echocardiography difference of the IABP and the control group in 10 days, 3 months, and 6 months also showed statistical significance （P 〈 0.05）. Conclusions IABP can significantly reduce the release of vasoactive substances of NR in patients of primary PCI for AMI; LAMD, LVMD and LVEF in 10 days, 3 months, and 6 months can be improved using this method, which is conducive to recovery of heart function.

Methods Clinical data of 22 acute myocardial infarction patients after PCI with angiographic no-reflow phenomenon were retrospectively analyzed between January 2006 and December 2009.12 patients underwent IABP, other 10 patients as control group. We observed difference of cardiac structure, brain natriuretic peptide （BNP） and ventricular systolic function between two group, as well as cardiac injury markers （MYO,CK-MB, cTnI） in both groups on the days of 1, 2, 3, 5, 7, 10 after the different interventions. In addition, cardiac structure and ventricular systolic function including left atrium medial diameter （LAMD）, left ventricular medial diameter （LVMD）, left ventricular ejection fraction （LVEF） was evaluated after 10 days, 3 months,6 months Finally, statistics was used to analysis the data. Results The several vasoactive substances as well as cardiac injury markers and LAMD, LVMD, LVEF of 10 days, 3 months, 6 months of IABP group were significant difference with control group significant difference （P 〉 0.0 PCI with angiographic no-reflo （P 〈 0.05）. 5）. Conclusions w phenomenon, BNP targets of IABP group compared with the control group no IABP has effects on prognosis in STEMI patients who performed which is conducive to recovery of heart function.

Peri-operative application of intra-aortic balloon pumping reduced in-hospital mortality of patients with coronary artery disease and left ventricular dysfunction

Background:There are few reports of peri-operative application of intra-aortic balloon pumping(IABP)in patients with coronary artery disease(CAD)and different grades of left ventricular dysfunction.This study aimed to analyze the early outcomes of perioperative application of IABP in coronary artery bypass grafting(CABG)among patients with CAD and left ventricular dysfunction,and to provide a clinical basis for the peri-operative use of IABP.Methods:A retrospective analysis of 612 patients who received CABG in the General Hospital of People's Liberation Army between May 1995 and June 2014.Patients were assigned to an IABP or non-IABP group according to their treatments.Logistic regression analysis was performed to investigate the influence of peri-operative IABP implantation on in-hospital mortality.Further subgroup analysis was performed on patients with severe(ejection fraction[EF]≤35%)and mild(EF=36%-50%)left ventricular dysfunction.Results:Out of 612 included subjects,78 belonged to the IABP group(12.7%)and 534 to the non-IABP group.Pre-operative left ventricular EF(LVEF)and EuroSCOREII·predicted mortality was higher in the IABP group compared with the non-IABP group(P<0.001 in both cases),yet the two did not differ significantly in terms of post-operative in-hospital mortality(P=0.833).Regression analysis showed that IABP implantation,recent myocardial infarction,critical status,non-elective operation,and postoperative ventricular fibrillation were risk factors affecting in-hospital mortality(P<0.01 in all cases).Peri-operative IABP implantation was a protective factor against in-hospital mortality(P=0.0010).In both the severe and mild left ventricular dysfunction subgroups,peri-operative IABP implantation also exerted a protective role against mortality(P=0.0303 and P=0.0101,respectively).Conclusions:Peri-operative IABP implantation could reduce the in-hospital mortality and improve the surgical outcomes of patients with CAD with both severe and mild left ventricular dysfunction.

Effects on the renal artery blood flow during the intra-aortic balloonpumping was used

The effects of intra-aortic balloon pumping(IABP) on hemodynamic parameters inthe kidney were studied. The pulse produced by pumping activated the renal nervoussystem and reduced the renal vascular resistance. Therefore, the reduction of the renalvascular resistance is an important reason for the increase the renal blood flow duringintra-aortic balloon pumping.

Role of Intra-Aortic Balloon Pump in Off-Pump Coronary Artery Bypass —A Vettath Modification

Objective: Hemodynamic deterioration during positioning of the heart has been the most critical complication of off-pump coronary artery bypass surgery. Pre-operative use of intra-aortic balloon pump has been shown to prevent this complication in high risk patients. The role of balloon pump in high risk patients has been questioned by our group. We modified the role of balloon pump in our patients, thus avoiding the conversion to cardiopulmonary bypass. Methods: 4063 off-pump coronary bypass surgeries were performed by a single surgeon in our center, over thirteen years. 130 intra-aortic balloons used between July 2002 and December 2015 were removed from the the-ater, once the distal anastomosis was performed. We studied this group of patients for—time and need for insertion, duration of balloon used, local insertion problems and survival. Results: Initially, we inserted intra-aortic balloons in high risk patients. We observed that, patients with low ejection fraction and patients with critical left main coronary artery disease were not the ones who actually needed balloon pump support. It was the patients who had ongoing ischemia, with preserved left ventricular function, and ST depression intra-operatively, who needed balloon pump support to perform complete anatomical revascularization. Conclusions: Intra-aortic balloon pump has helped us to position the heart without hemodynamic instability, thereby avoiding conversion to cardio-pulmonary bypass. This enabled us to perform off-pump surgery in virtually all areas of the heart, thus maintaining perfect hemodynamics.

A CLOSED LOOP,FULLY AUTOMATIC INTRA-AORTIC BALLOON PUMP SYSTEM

Since its introduction in 1967,intra-aortic balloon pumping (IABP) has becomethe mainstay in the management of acute left ventricular dysfunction in the criticalcare setting.Typically,present IABP systems are unable to provide consistent,effective car-diac assistance in the presence of arrhythmias or rapidly changing heart rates.Anew-generation,closed loop,fully automatic intra-aortic balloon pump (CL-IABP)

Preoperative Intra-Aortic Balloon Counterpulsation in Coronary Artery Bypass Graft Patients with Severe Left Ventricular Dysfunction

Background: The intra-aortic balloon pumping (IABP) is the most used ventricular mechanical assist device. In recent years, the preoperative use in patients with severe ventricular dysfunction presents itself as a great benefic strategy to the postoperative recovery. This paper aim is to evaluate the IABP post-operative benefit in patients with severe ventricular dysfunction. Methods: From January 2011 to March 2016, 125 patients underwent a coronary artery bypass graft (CABG) with cardiopulmonary bypass and preoperative IABP in Teaching Hospital of the ABC Medical School and Hospital Estadual Mario Covas. The inclusion criteria were the presence of severe ischemic cardiomyopathy with left ventricular ejection fraction (LVEF) less than or equal to 40%, estimated by Doppler echocardiography using the Simpson method. The preoperative LVEF was 30.25% ± 8.53% and the diastolic diameter of the left ventricle (LVDD) 67.75 ± 16.37 mm. IABP was installed approximately 15 hours before the surgery. Results: The patients required the IABP for 2.4 ± 1.58 days, and vasoactive drugs, 4.8 ± 2.12 days. We performed 3.2 ± 1.9 grafts per patient and the total length of stay was 07 ± 5.52 days. Cardiopulmonary bypass time was 67 ± 10.95 minutes and anoxia time, 46.4 ± 10.06 minutes. Twelve patients (9.6%) had pneumonia and four (3.2%), atrial fibrillation. We observed a LVDD reduction to 63 ± 16.26 (p = 0.068) and LVEF enhancement to 36.50 ± 16.86 (p = 0.144). The data were analyzed statistically according to the Wilcoxon test. There were no deaths. Conclusion: The initial experience of the authors with the preoperative IABP in patients with severe left ventricular dysfunction suggests great benefit in post-operative recovery with im-provement of LVEF and reduction of LVDD.

Anticoagulation therapy in intra-aortic balloon counterpulsation： Does IABP really need anti-coagulation ？

Objective: To investigate if intra-aortic balloon pump(IABP) is contraindicated without anticoag-ulation therapy. Methods: Some 153 IABP patients in the King Abdulaziz Cardiac Center(KSA) were random-ly assigned into two groups. Anticoagulation group( Group A) consisted of 71 patients who were given heparin intravenously with target aPTT 50 - 70 seconds. Non-anticoagulation group( Group B) consisted of 82 patients without intravenous heparin during balloon pumping. Hematological parameters including platelet count, D-dimer, Plasminogen activator inhibitor-1 (PAI-1) and fibrinogen degradation products(FDP) were checked respectively at the point of baseline, 24 hours, 48 hours and 24 hours post IABP counterpulsation. Clot deposits on balloon surface, vascular complications from IABP including bleeding and limb ischemia were recorded.Results: Platelet count and PAI-1 level decreased at 24 hours and 48 hours in both groups ( P < 0.05) . D-dimer and FDP level increased at 24 hours and 48 hours in both groups( P < 0.05), but returned to the baseline level 24 hours post IABP removal( P > 0.05) . Three patients in Group A and 2 patients in Group B developed minor limb ischemia( P > 0.05). No major limb ischemia in either group. Two patients in Group A suffered major bleeding and required blood transfusion or surgical intervention, whereas no patient had major bleeding in Group B. Eight patients had minor bleeding in Group A, but only 2 patients in Group B ( P <0.05). No clot deposit developed on IABP surface in either group. Conclusion: IABP is safe without routine anticoagulation therapy. Selecting appropriate artery approach and early detection intervention are key methods for preventing complications.
