What this trial studies

MIRAMACS is an independent, nationwide observational registry coordinated by the Cardiac Surgery Department at IRCCS Sant'Orsola in Bologna that combines retrospective data from January 2010 with prospective enrollment across major Italian referral centers. The registry captures clinical outcomes and device performance for adult patients implanted with second- and third-generation radial continuous-flow VADs, including implantable BIVADs. The primary focus is on survival during hospitalization and at one and five years after implantation, while secondary outcomes include length of hospital and ICU stay, duration of mechanical ventilation, and incidence of device-related adverse events. Data are collected using a structured REDCap platform to standardize reporting and enable multicenter collaboration.

Who should consider this trial

Good fit: Adults with advanced heart failure refractory to maximal medical therapy who receive implantable continuous-flow radial VADs (including second- and third-generation axial or centrifugal pumps and implantable BIVADs) are the intended participants.

Not a fit: Children and patients treated with paracorporeal pulsatile devices, total artificial hearts, or other mechanical devices not specified in the protocol are unlikely to benefit from this registry's findings.

Why it matters

Potential benefit: If successful, the registry could give clinicians clearer, real-world information on long-term survival and device risks to help improve patient selection and post-implant care.

How similar studies have performed: Previous large registries and trials of continuous-flow ventricular assist devices have demonstrated improved survival and reduced complications compared with older technologies, although comprehensive nationwide registries focused specifically on radial systems are less common.
