Article Abstract
Background: Heterotopic heart transplantation is a surgical technique that has not been embraced broadly. In this historic technique, the donor heart is sutured in parallel to the recipient heart with both hearts in place.
Case Summary: We report a patient who received a heterotopic heart transplant at our institution more than 15 years ago with preserved cardiac function and who needed a myocardial biopsy due to heart failure symptoms. Due to complex anatomy, a cardiac computed tomography imaging reconstruction was used to create a live roadmap overlay on fluoroscopy during myocardial biopsy. Such a technique facilitated obtaining a biopsy successfully and safely to rule out rejection.
Discussion: Heterotopic heart transplantation is a surgical procedure that has a potential physiologic and immunologic advantage in select patients needing a heart transplant. Utilizing imaging guidance for navigating complex anatomy to perform a myocardial biopsy can have potential applications in providing safe and increasing yield in patchy diseases of the heart.

Background: Caval valve implantation is currently the only alternative for patients with severe tricuspid regurgitation (TR) who are deemed unsuitable candidates for transcatheter orthotopic therapies.
Objectives: The aim of this study was to assess the efficacy and safety of TricValve system at 1-year follow-up.
Methods: TricBicaval registry is a multicenter registry that retrospectively enrolled all consecutive patients with severe TR treated with TricValve system.

Severe, symptomatic tricuspid regurgitation is a progressive disease with poor prognosis and limited treatment options. TricValve (bicaval, heterotopic valve system) implantation is a new palliative treatment option. The stented bioprosthesis are implanted in the inferior and superior caval veins without interveniening with the native tricuspid valve.

Ventricular assist devices have been widely accepted as an alternative treatment for advanced heart failure, while heart transplantation is a limited procedure because of the shortage of donors. In face of a scarce availability of these devices, many centers around the world have developed their own technologies. We describe historical and general features of the main ventricular assist devices developed at the Instituto Dante Pazzanese de Cardiologia.

Cardiac atrophy is the most common complication of prolonged application of the left ventricle (LV) assist device (LVAD) in patients with advanced heart failure (HF), obviously, it is a consequence of LVAD-induced mechanical unloading. Previous studies employing heterotopic heart transplantation (HTx) as a model of heart unloading after LVAD implantation discovered sex-linked differences in the course of unloading-induced in the healthy hearts. It remains to be clarified if sex-related differences are present in the failing hearts after heterotopic HTx.

Rationale: The coexistence of intrauterine and extrauterine pregnancies is termed heterotopic pregnancy (HP). Most reported cases of HP occur after assisted reproductive technology, and HP in a natural pregnancy (NP) is very rare, often discovered intraoperatively. HP is a significant challenge for obstetricians, gynecologists, and sonographers.
