OBJECTIVES: To evaluate the 30-day postoperative mortality and palliative care consultations in patients that underwent surgical procedures in the United States before and after Medicare Access and Children’s Health Insurance Program Reauthorization Act (MACRA) implementation. DESIGN: Retrospective, Observational cohort study. SETTING: Secondary data were collected from the U.S. National Inpatient Sample, the largest hospital database in the country. The time span was from 2011 to 2019. PATIENTS: Adult patients that electively underwent 1 of 19 major procedures. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The primary outcome was cumulative postoperative mortality in two study cohorts. The secondary outcome was palliative care use. We identified 4,900,451 patients and categorized them into two study cohorts: PreM: 2011–2014 (n = 2,103,836) and PostM: 2016–2019 (n = 2,796,615). Regression discontinuity estimates and multivariate analysis were used. Across all procedures, 149,372 patients (7.1%) and 156,610 patients (5%) died within 30 days of their index procedures in the PreM and PostM cohorts, respectively. There was no statistically significant increase in mortality rates around postoperative day (POD) 30 (POD 26–30 vs 31–35) for both cohorts. More patients had inpatient palliative consultations during POD 31–60 compared with POD 1–30 in PreM (8,533 of 2,081,207 patients [0.4%] vs 1,118 of 22,629 patients [4.9%]) and PostM (18,915 of 2,791,712 patients [0.7%] vs 417 of 4,903 patients [8.5%]). Patients were more likely to receive palliative care consultations during POD 31–60 compared with POD 1–30 in both the PreM (odds ratio [OR] 5.31; 95% CI, 2.22–8.68; p < 0.001) and the PostM (OR 7.84; 95% CI, 4.83–9.10; p < 0.001) cohorts. CONCLUSIONS: We did not observe an increase in postoperative mortality after POD 30 before or after MACRA implementation. However, palliative care use markedly increased after POD 30. These findings should be considered hypothesis-generating because of several confounders.

Abstract Aims We sought to investigate the outcomes of heart transplant patients supported with Impella 5.5 temporary mechanical circulatory support. Methods and results Patient demographics, perioperative data, hospital timeline, and haemodynamic parameters were followed during initial admission, Impella support, and post-transplant period. Vasoactive-inotropic score, primary graft failure, and complications were recorded. Between March 2020 and March 2021, 16 advanced heart failure patients underwent Impella 5.5 temporary left ventricular assist device support through axillary approach. Subsequently, all these patients had heart transplantation. All patients were either ambulatory or chair bound during their temporary mechanical circulatory support until heart transplantation. Patients were kept on Impella support median of 19 days (3–31) with the median lactate dehydrogenase level of 220 (149–430). All Impella devices were removed during heart transplantation. During Impella support, patients had improved renal function with median creatinine serum level of 1.55 mg/dL decreased to 1.25 (P = 0.007), pulmonary artery pulsatility index scores increased from 2.56 (0.86–10) to 4.2 (1.3–10) (P = 0.048), and right ventricular function improved (P = 0.003). Patients maintained improved renal function and favourable haemodynamics after their heart transplantation as well. All patients survived without any significant morbidity after their heart transplantation. Conclusions Impella 5.5 temporary left ventricular assist device optimizes care of heart transplant recipients providing superior haemodynamic support, mobility, improved renal function, pulmonary haemodynamics, and right ventricular function. Utilizing Impella 5.5 as a direct bridging strategy to heart transplantation resulted in excellent outcomes.

Abstract Haemorrhagic pericardial cysts are rare and may be complicated by encasement of the heart, right heart failure and, rarely, cardiac cirrhosis. Surgical management of complicated cysts is challenging and has poor outcomes. We report a case of successful surgical management of a complicated pericardial cyst presenting with cardiac cirrhosis and the challenges associated with this condition.

One of the signicant obstacles to donor heart utilization is that increasingly prolonged cold ischemic times are associated with worsened short- and long-term outcomes. As a result, most transplant centers aim to limit cold ischemic times to less than four hours. The TransMedics Organ Care System (OCS) (Trans Medics, Andover MA) is a portable ex vivo perfusion system designed to store a donor heart in a beating, metabolically active state, until it reaches the recipient, thereby allowing extended time outside the body while minimizing the effects of cold storage. We present a case of a heart transplant recipient supported with the Impella 5.5 as a bridge to transplantation who received a donation after circulatory death (DCD) heart supported by OCS. To our knowledge, this is the rst report of such a case.

For donation after circulatory death, procurement is performed after the heart has arrested. This technique has been employed and adopted by clinicians to overcome the shortage of available hearts for transplant. Warm ischemia time plays a pivotal role in the survival outcome of the heart recipients. We describe a fast and safe technique to flush the heart during recovery from circulatory death donors in order to shorten the warm ischemia time.
