ECMO Alone Versus ECPELLA in Patients Affected by Cardiogenic Shock: The Multicenter EVACS Study.

The objective was to investigate the outcomes of concomitant venoarterial extracorporeal membrane oxygenation (ECMO) and left ventricular unloading with Impella (ECPELLA) compared with ECMO alone to treat patients affected by cardiogenic shock. Data from patients needing mechanical circulatory support from 4 international centers were analyzed. Of 438 patients included, ECMO alone and ECPELLA were adopted in 319 (72.8%) and 119 (27.2%) patients, respectively. Propensity score matching analysis identified 95 pairs. In the matched cohort, 30-day mortality rates in the ECMO and ECPELLA were 49.5% and 43.2% ( P = 0.467). The incidences of complications did not differ significantly between groups ( P = 0.877, P = 0.629, P = 1.000, respectively). After a median follow-up of 0.18 years (interquartile range 0.02-2.55), the use of ECPELLA was associated with similar mortality compared with ECMO alone (hazard ratio 0.81, 95% confidence interval 0.54-1.20, P = 0.285), with 1-year overall survival rates of 51.3% and 46.6%, for ECPELLA and ECMO alone, respectively. ECMO alone and ECPELLA are both effective strategies in patients needing mechanical circulatory support for cardiogenic shock, showing similar rates of early and mid-term survival.

Hybrid extracorporeal membrane oxynegation in pediatric intensive care patients: A single center experience: More is better?

BACKGROUND: The initial extracorporeal membrane oxygenation (ECMO) configuration is inefficient for patient oxygenation and flow, but by adding a Y-connector, a third or fourth cannula can be used to support the system, which is called hybrid ECMO. METHODS: This was a single-center retrospective study consisting of patients receiving hybrid and standard ECMO in our PICU between January 2014 and January 2022. RESULTS: The median age of the 12 patients who received hybrid ECMO and were followed up with hybrid ECMO was 140 (range, 82-213) months. The total median ECMO duration of the patients who received hybrid ECMO was 23 (8-72) days, and the median follow-up time on hybrid ECMO was 18 (range, 3-46) days. The mean duration of follow-up in the PICU was 34 (range, 14-184) days. PICU length of stay was found to be statistically significant and was found to be longer in the hybrid ECMO group (p = 0.01). Eight (67%) patients died during follow-up with ECMO. Twenty-eight-day mortality was found to be statistically significant and was found to be higher in the standard ECMO group (p = 0.03). The hybrid ECMO mortality rate was 66% (decannulation from ECMO). The hybrid ECMO hospital mortality rate was 75%. The standard ECMO mortality rate was 52% (decannulation from ECMO). The standard ECMO hospital mortality rate was 65%. CONCLUSIONS: Even though hybrid ECMO use is rare, with increasing experience and new methods, more successful experience will be gained. Switching to hybrid ECMO from standard ECMO at the right time with the right technique can increase treatment success and survival.

Single or Combined Valve Surgery and Concomitant Right Coronary Artery Bypass through Right Anterior Minithoracotomy Approach.

BACKGROUND: Patients with combined valve and coronary artery disease are commonly performed by standard median sternotomy approach for coronary artery bypass grafting (CABG) and valve surgery. The purpose of this study is to describe our experience and show feasibility and safety of minimally invasive approach to single or combined valve pathology with single-vessel right coronary artery (RCA) disease, even if it is suitable to percutaneous coronary intervention. METHODS: This retrospective study comprised 28 consecutive patients who underwent single or combined valve surgery concomitant right CABG through right anterior minithoracotomy between February 2018 and December 2020. Preoperative evaluation, intraoperative, and postoperative outcomes were reviewed and analyzed. RESULTS: There were 12 men and 16 women. The mean age was 71.46 ± 6.82 years. Ten patients were in New York Heart Association class III or IV. The mean cardiopulmonary bypass and aortic cross-clamping times were 117.6 ± 21.3 and 98.1 ± 22.6 minutes, respectively. The mean time to extubation was 9.7 ± 5.6 hours, the mean intensive care unit stay was 37.4 ± 14.6 hours, and the mean hospital stay was 6.9 ± 3.2 days. There was one patient who underwent reoperation for bleeding. There were no instances of postoperative stroke, myocardial infarction, renal failure, or wound infection. The mean follow-up was 19 ± 2.4 months. CONCLUSION: Presence of RCA lesion is not a contraindication for minimally invasive approach in cases who underwent single or combined valve surgery. Combined valve surgery and right CABG via right anterior minithoracotomy are a safe and feasible option to standard median sternotomy surgery, even if RCA lesions seem suitable for stenting.

Endovascular balloon angioplasty for infrainguinal arterial occlusive disease: Efficacy analysis.

BACKGROUND: We present early and mid-term clinical outcomes of endovascular revascularization for femoropopliteal involvement of peripheral arterial disease. METHODS: A total of 128 patients (113 males, 15 females; mean age: 63.4±9.9 years; range, 32 to 87 years) who underwent percutaneous transluminal angioplasty for femoropopliteal lesions between August 2016 and April 2018 were analyzed retrospectively. Treatment with Luminor® paclitaxel-coated drug-eluting balloon catheter or bailout therapy with iVolution® self-expanding nitinol stent were performed. Overall patency rates and freedom from reintervention rates were analyzed using the Kaplan-Meier analysis. The primary patency and freedom from reintervention to target lesion rates at 12 and 24 months were evaluated. RESULTS: Technical success was achieved in 133 (93%) of the interventions with a median follow-up of 11 (range, 1 to 35) months. At 12 and 24 months, the mean overall patency rates were 85.6±3.7% and 66.8±6.7%, respectively and the mean freedom from reintervention to target lesion rates were 91.6±2.9% and 78.1±6.3%, respectively. The primary patency and freedom from reintervention to target lesion rates were significantly higher in the bailout stenting group than the drug-eluting balloon group at 12 months (97.3±2.7% vs. 94.8±6.1%, respectively, p=0.025 and 97.1±2.9% vs. 84.2±5.5%, respectively, p=0.005) and at 24 months (76.9±7.9% vs. 55.8±13.4%, respectively, p=0.025 and 85.2±7.0% vs. 70.2±13.6%, respectively, p=0.005). CONCLUSION: Endovascular procedures including drug-eluting balloon and bailout stenting seem to be effective alternative treatment modalities for treatment of infrainguinal peripheral arterial disease and can be also used in patients with long lesions and/or total occlusion of femoropopliteal arteries.

Comparison of left ventricular unloading strategies on venoarterial extracorporeal life support.

OBJECTIVES: Our goal was to compare the haemodynamic effects of different mechanical left ventricular (LV) unloading strategies and clinical outcomes in patients with refractory cardiogenic shock supported with venoarterial extracorporeal membrane oxygenation (VA-ECMO). METHODS: A total of 448 patients supported with VA-ECMO for refractory cardiogenic shock between 1 March 2015 and 31 January 2020 were included and analysed in a single-centre, retrospective case-control study. Fifty-three patients (11.8%) on VA-ECMO required LV unloading. Percutaneous balloon atrial septostomy (PBAS), intra-aortic balloon pump (IABP) and transapical LV vent (TALVV) strategies were compared with regards to the composite rate of death, procedure-related complications and neurological complications. The secondary outcomes were reduced pulmonary capillary wedge pressure, pulmonary artery pressure, central venous pressure, left atrial diameter and resolution of pulmonary oedema on a chest X-ray within 48 h. RESULTS: No death related to the LV unloading procedure was detected. Reduction in pulmonary capillary wedge pressure was highest with the TALVV technique (17.2 ± 2.1 mmHg; P < 0.001) and was higher in the PBAS than in the IABP group; the difference was significant (9.6 ± 2.5 and 3.9 ± 1.3, respectively; P = 0.001). Reduction in central venous pressure with TALVV was highest with the other procedures (7.4 ± 1.1 mmHg; P < 0.001). However, procedure-related complications were significantly higher with TALVV compared to the PBAS and IABP groups (50% vs 17.6% and 10%, respectively; P = 0.015). We observed no significant differences in mortality or neurological complications between the groups. CONCLUSIONS: Our results suggest that TALVV was the most effective method for LV unloading compared with PBAS and IABP for VA-ECMO support but was associated with complications. Efficient LV unloading may not improve survival.

Percutaneous ultrasound-guided versus bronchoscopy-guided dilatational tracheostomy after median sternotomy: A case-control study.

BACKGROUND: In this study, we aimed to compare ultrasoundguided versus bronchoscopy-guided percutaneous dilatational tracheostomy outcomes in critically ill adult patients undergoing a median sternotomy. METHODS: Between January 2015 and December 2020, a total of 54 patients (17 males, 37 females; mean age: 54.9±13.1 years; range, 39 to 77 years) who underwent elective ultrasound- or bronchoscopy-guided percutaneous dilatational tracheostomy after a median sternotomy were included. We compared the ultrasound-guided group (n=25) with the bronchoscopy-guided group (n=29) regarding all-cause mortality and complications. Safety assessments included major and minor bleeding, procedural hypoxic or hypotensive event, cardiac dysrhythmias, tracheal injury, damage to adjacent structures, and requirement of conversion to open surgical tracheostomy. RESULTS: No tracheostomy procedure-related death was observed in either group. The median time for tracheostomy was 13 (range, 8 to 17) min in the ultrasound-guided group and 10 (range, 7 to 15) min in the bronchoscopy-guided group (p=0.387). There was no need for conversion between the two methods or conversion to surgical tracheostomy for any patient. The overall complication rates did not significantly differ between the groups (p=0.15). CONCLUSION: Ultrasound-guided percutaneous dilatational tracheostomy can be safely performed in patients undergoing sternotomy. Complication rates of the procedure are similar to those guided with bronchoscopy.

Endovascular Treatment of Infra-inguinal Arterial Occlusive Disease in Patients with Diabetes.

OBJECTIVE: To present the early and mid-term results of PTA for femoropopliteal lesions in diabetic patients, performed by the cardiovascular surgeons. STUDY DESIGN: Experimental study. PLACE AND DURATION OF STUDY: Department of Cardiovascular Surgery, Ankara City Hospital, Turkey, from August 2015 to April 2018. METHODOLOGY: Seventy-nine patients with diabetes mellitus (DM) and lower limb arterial occlusive disease underwent endo-interventions causing Rutherford Class 2-5 pedal ischemia. Study end points included ankle brachial index (ABI) and primary patency (PP) evaluated through Kaplan-Meier analyses. RESULTS: The technical success rate was 92.4% with a mean follow-up period of 13.3 ± 9.2 months. Bailout stenting was required in 27 (34.2%) of the lesions and only 7 (8.9%) patients required percutaneous reintervention at the end of the follow-up period. Kaplan-Meier analysis of the bailout stenting group revealed higher primary patency and lower reintervention rates at 24 months when compared with the PTA group (70.8%, 57.7%  and 80.5% 65.9%, respectively). CONCLUSION: Endovascular procedures can be performed by cardiovascular surgeons in the early and mid-term with high success and low complication rates in patients with diabetes mellitus.

A retrospective cohort analysis of percutaneous versus side-graft perfusion techniques for veno-arterial extracorporeal membrane oxygenation in patients with refractory cardiogenic shock.

OBJECTIVES: This study was designed to compare vascular complications and the outcomes of ultrasound (US)-guided percutaneous cannulation with distal perfusion catheter (PC-DP) and arterial side-graft perfusion (SGP) techniques in patients who require veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support for refractory cardiogenic shock (RCS). METHODS: We conducted a retrospective, observational cohort study of consequtive patients with RCS treated with VA-ECMO at a single transplant center from March 2010 until August 2015. Overall, 148 patients underwent VA-ECMO for RCS (99 men, aged 56.6 ± 12.0 years; BSA, 1.85 ± 0.19). Patients were categorized based on VA-ECMO perfusion technique into PC-DP via femoral artery and SGP via axillary/femoral artery groups. RESULTS: The median duration of VA-ECMO support was 5 days (range, 8 hours-80 days). Hospital mortality (PC-DP group, 54.7%; SGP group, 64.4%; p=0.23) and overall ECMO survival (PC-DP group, 36.9%; SGP group, 32.2%; p=0.47) was similar between the groups. There were no significant between-group differences in the rate of acute limb ischemia (PC-DP group, 4/75, 5.3%; SGP group, 2/73, 2.7%; p=0.68). However, the rate of surgical/cannulation site bleeding (PC-DP, 9/75 (12%) vs SGP, 18/73 (24.7%), p=0.05) and hyperperfusion syndrome (PC-DP, 2/75 (2.7%) vs SGP, 22/73 (30.1%),p=0.001) were higher in the SGP group than in the PC-DP group. CONCLUSIONS: We observed no significant difference in major vascular complications or survival between patients who underwent the PC-DP technique and those who underwent arterial SGP.
