Durable ventricular assist device in Spain (2007-2020). First report of the REGALAD registry.

INTRODUCTION AND OBJECTIVES: This report presents the clinical characteristics, outcomes and complications of all consecutive patients implanted with a long-term mechanical circulatory support device in Spain between 2007 and 2020. METHODS: Analysis of the Spanish Registry of durable ventricular assist devices (REGALAD) including data form Spanish centers with a mechanical circulatory support program. RESULTS: During the study period, 263 ventricular assist devices were implanted in 22 hospitals. The implanted device was an isolated continuous-flow left ventricular assist device in 182 patients (69%), a pulsatile-flow device (58 isolated left ventricular and 21 biventricular) in 79 (30%), and a total artificial heart in 2 patients (1%). The strategy of the implant was as bridge to heart transplant in 78 patients (30%), bridge to candidacy in 110 (42%), bridge to recovery in 3 (1%) and destination therapy in 72 patients (27%). Overall survival at 6, 12 and 24 months was 79%, 74% and 69%, respectively, and was better in continuous-flow left ventricular assist devices (84%, 80%, and 75%). The main adverse events related to this therapy were infections (37% of patients), bleeding (35%), neurological (29%), and device malfunction (17%). CONCLUSIONS: Durable ventricular assist devices have emerged in Spain in the last few years as a useful therapy for patients with advanced heart failure. As in other international registries, the current trend is to use continuous-flow intracorporeal left ventricular devices, which are associated with better results. Adverse events continue to be frequent and severe.

Clinical evaluation of rosuvastatin in heart transplant patients with hypercholesterolemia and therapeutic failure of other statin regimens: short-term and long-term efficacy and safety results.

We conducted an observational study of 30 heart transplant recipients with serum low-density lipoprotein cholesterol (LDL-c) >100 mg/dl despite previous statin therapy, who were treated with rosuvastatin 10 mg daily (5 mg in case of renal dysfunction). Serum lipids, creatine phosphokinase (CPK), bilirubin, and hepatic enzymes were prospectively measured 2, 4, and 12 weeks after the initiation of the drug. Clinical outcomes of patients who continued on long-term rosuvastatin therapy beyond this 12-week period were reviewed in February 2015. Over the 12-week period following rosuvastatin initiation, serum levels of total cholesterol (TC) and LDL-c and the ratio TC/high-density lipoprotein cholesterol (HDL-c) decreased steadily (P < 0.001). Average absolute reductions of these three parameters were -48.7 mg/dl, -46.6 mg/dl, and -0.9, respectively. Seventeen (57%) achieved a serum LDL-c < 100 mg/dl. No significant changes from baseline were observed in serum levels of triglycerides, HDL-c, hepatic enzymes, bilirubin, or CPK. Twenty-seven (90%) patients continued on long-term therapy with rosuvastatin over a median period of 3.6 years, with no further significant variation in lipid profile. The drug was suspended due to liver toxicity in 1 (3.3%) patient and due to muscle toxicity in 2 (6.7%) patients. All adverse reactions resolved rapidly after rosuvastatin withdrawal. Our study supports rosuvastatin as a reasonable alternative for heart transplant recipients with hypercholesterolemia and therapeutic failure of other statin regimens.
