Submammary device implantation. Good long-term performance and better patients' satisfaction. A single-center experience.

Introduction: Device related distress negatively affects the quality of life of cardiac device recipients mostly of women. A submammary approach has been proposed to reduce the physical impact of the implantation. Our aim was to assess the safety of this approach and to evaluate the patients' acceptance of the device.
Methods: We enrolled 42 patients who underwent a submammary device. The primary endpoint was the need for implant revision that was assessed in the study group compared with the overall control group of 72 standard cardiac device recipients (29 females and 43 males)and with the female group (29 females of controls). In the female population (42 women of the submammary group and 29 of controls) patients' acceptance was calculated with the Florida Patient Acceptance Survey (FPAS).
Results: The rate of implant revision was similar in the two groups and the revision-free survival was comparable with a median follow-up of about six years (Log rank test p=0.949). Similar results were found when considering only the female population. Patients' acceptance was greater in the submammary group [total FPAS 85 (95%CI 83-86) vs 74.5 (95%CI 70.2-77.3) p<0,001] and a strongly significant superiority of the submammary group was found regarding body image concerns [10 (95%CI 10-10) vs 8 (95%CI 8-8) p<0.001) and device related distress [23 (95%CI 22-23) vs 1 (95%CI 1-1) p<0.001].
Conclusions: Submammary device implantation is safe and more accepted than standard approach. Our results should encourage cardiologists to suggest this approach to their patients for a better acceptance of the therapy.
