Cardiac light chain (AL) amyloidosis is a condition with a very poor prognosis. We report a retrospective analysis comparing the traditional melphalan and dexamethasone protocol with cyclophosphamide, bortezomib and dexamethasone in late-stage cardiac AL amyloidosis. The primary end points were overall survival and haematological response. Both regimens provided meaningful responses in this difficult to treat patient group.

Autologous haematopoietic stem cell transplantation is now well-established as an effective treatment for severe systemic sclerosis with clear demonstration of favourable end-organ and survival outcomes. Treatment-related cardiotoxicity remains the predominant safety concern and contraindicates autologous haematopoietic stem cell transplantation in patients with severe cardiopulmonary disease. In this review, we describe the cardiovascular outcomes of autologous haematopoietic stem cell transplantation recipients, discuss the potential mechanisms of cardiotoxicity and propose future mitigating strategies.

We present the first published case of successfully treated disseminated Aspergillus lentulus infection in a solid organ transplant recipient with invasive pulmonary disease, endophthalmitis, and a cerebral abscess. This case highlights important challenges associated with treating A. lentulus, particularly regarding antifungal resistance and toxicities associated with long-term antifungal therapy.

BACKGROUND The aim of this study was to validate our previous finding that frailty predicts early mortality in patients with advanced heart failure (AHF) and that including cognition in the frailty assessment enhances the prediction of mortality. METHODS Patients with AHF referred to our Transplant Unit between November 2015 and April 2020 underwent physical frailty assessment using the modified Fried physical frailty (PF) phenotype as well as cognitive assessment using the Montreal Cognitive Assessment (MOCA) to identify patients who were cognitively frail (CogF). We assessed the predictive value of the 2 frailty measures (PF ≥ 3 of 5 = frail; CogF ≥ 3 of 6 = frail) for pretransplant mortality. RESULTS 313 patients (233 male, 80 female; age 53 ± 13 years) were assessed. Of these, 224 patients (72%) were nonfrail and 89 (28%) were frail using the PF. The cognitive frailty assessment identified an additional 30 patients as frail: 119 (38%). Frail patients had significantly increased mortality as compared to nonfrail patients. Ventricular assist device and heart transplant-censored survival at 12 months was 92 ± 2 % for nonfrail and 69 ± 5% for frail patients (p < 0.0001) using the CogF instrument. CONCLUSIONS This study validates our previously published findings that frailty is prevalent in patients with advanced heart failure referred for heart transplantation. Physical frailty predicts early mortality. The addition of cognitive assessment to the physical assessment of frailty identifies an additional cohort of patients with a similarly poor prognosis.

BACKGROUND: Frailty is associated with adverse outcomes in advanced heart failure. We studied the impact of frailty on postoperative outcomes in bridge to transplant (BTT) durable mechanical circulatory support (MCS) recipients. METHODS: Patients undergoing left ventricular assist device (LVAD, n = 96) or biventricular support (BiV, n = 11) as BTT underwent frailty assessment. Frailty was defined as ≥ 3 physical domains of the Fried's Frailty Phenotype (FFP) or ≥ 2 physical domains of the FFP plus cognitive impairment on the Montreal Cognitive Assessment (MoCA). RESULTS: No difference in mortality at 360 days was observed in frail (n = 6/38, 15.8%) vs non-frail (n = 4/58, 6.9%) LVAD supported patients, p = 0.19. However, there was a significant excess mortality in frail BiV (n = 4/5) vs non-frail BiV (n = 0/6) supported patients, p = 0.013. In all patients, frail patients compared to non-frail patients experienced longer intensive care unit stay, 12 vs 6 days (p < 0.0001) and hospital length of stay, 48 vs 27 days (p < 0.0001). There was no difference in hemocompatibility and infection related adverse events. The majority (n = 22/29, 75.9%) of frail patients became non-frail following MCS; contrastingly, a minority (n = 3/42, 7.1%) became frail from being non-frail (p = 0.0003). CONCLUSIONS: Abnormal markers of frailty are common in patients undergoing BTT-MCS support and those used herein predict mortality in BiV-supported patients, but not in LVAD patients. These findings may help us better identify patients who will benefit most from BiV-BTT therapy.

BACKGROUND Frailty is prevalent in the patients with advanced heart failure; however, its impact on clinical outcomes after heart transplantation (HTx) is unclear. The aim of this study was to assess the impact of pre-transplant frailty on mortality and the duration of hospitalization after HTx. METHODS We retrospectively reviewed the post-transplant outcomes of 140 patients with advanced heart failure who had undergone frailty assessment within the 6-month interval before HTx: 43 of them were frail (F) and 97 were non-frail (NF). RESULTS Post-transplant survival rates for the NF cohort at 1 and 12 months were 97% (93–100) and 95% (91–99) (95% CI), respectively. In contrast, post-transplant survival rates for the F cohort at the same time points were 86% (76–96) and 74% (60–84) (p < 0.0008 vs NF cohort), respectively. The Cox proportional hazards regression analysis demonstrated that pre-transplant frailty was an independent predictor of post-transplant mortality with a hazard ratio of 3.8 (95% CI: 1.4–10.5). Intensive care unit and hospital length of stay were 2 and 7 days longer in the F cohort (both p < 0.05), respectively, than in the NF cohort. CONCLUSIONS Frailty within 6 months before HTx is independently associated with increased mortality and prolonged hospitalization after transplantation. Future research should focus on the development of strategies to mitigate the adverse effects of pre-transplant frailty.

This study evaluated the effect of restrictive filling pattern (RFP) on 5-year outcomes in patients following ST-segment elevation myocardial infarction (STEMI). A hundred STEMI patients treated either by rescue or primary percutaneous coronary intervention with an echocardiogram performed within 6 weeks of STEMI comprised the study group. Creatinine kinase (CK) and left ventricular ejection fraction were independent determinants of RFP, and RFP was an independent predictor of cardiac and all-cause mortality at median follow up of 5 years.
