A 13-year-old boy with tetralogy of Fallot and pulmonary atresia after a Waterston and Blalock-Taussig shunt underwent successful repair using a cryopreserved pulmonary homograft as a valved extracardiac conduit. Aortic transection gave a good operative field for pulmonary angioplasty and closure of the Waterston anastomosis. The cryopreserved pulmonary homograft provided excellent handling characteristics. The postoperative course was good, and postoperative echocardiography showed good function of the valved conduit.

The Ross procedure continues to be the best procedure to address unrepairable aortic valve pathology, especially in young adults. The Achilles heel of this procedure has been aortic root dilation and the potential need for a reoperation that may be associated with slightly increased risks in addition to the need for intervention on the pulmonary outflow tract. Modifying the Ross procedure by autograft inclusion inside a Dacron graft seems to have the potential advantage of stabilizing the autograft diameter, which may be associated with improved durability and decrease the need for future intervention.

Background: The effect of anticoagulation on early postoperative outcomes following pulmonary valve replacement (PVR) with bioprosthetic valves and homografts is not yet defined. We hypothesized that short-term anticoagulation would be associated with improved valve durability.
Methods: Patients undergoing PVR or right ventricle-pulmonary artery conduits with a bioprosthetic or homograft valve >15 mm in diameter between 1/2015 and 4/2021 at Boston Children's Hospital were retrospectively compared by anticoagulation status.

The importance of mental toughness on lung transplant outcomes is unknown. We performed a pilot study to assess whether pretransplant grit and resilience are associated with short-term posttransplant outcomes. We enrolled 31 lung transplant candidates, of whom 7 (26%) had greater mental toughness, defined as the upper tertile for both grit and resilience within our cohort.

This report presents the case of a 66-year-old man with acute torrential aortic insufficiency after a Ross procedure 20 years earlier, a biologic aortic valve replacement 16 years earlier, and a transcatheter valve-in-valve 4 years earlier. He underwent third-time sternotomy, revealing that the pulmonary autograft was heavily calcified and frozen to the homograft. The previous transcatheter valve-in-valve was explanted.

Background: Coronary computed tomography angiography (CCTA) is emerging as a valuable tool for noninvasive surveillance of cardiac allograft vasculopathy (CAV) in patients with heart transplant (HTx). We assessed the diagnostic performance of a comprehensive CCTA-based approach compared with the invasive reference, which includes invasive coronary angiography, intravascular ultrasound, and fractional flow reserve, for detecting CAV.
Methods: This was a multicenter prospective study including 37 patients with HTx who underwent CCTA, invasive coronary angiography, intravascular ultrasound, and fractional flow reserve.
