Background: Thrombotic thrombocytopenic purpura (TTP) is a rare hematological disorder. The occurrence of TTP subsequent to an emergent aortic valve replacement after a TAVR procedure is exceedingly uncommon with only a few reported cases worldwide.
Case Presentation: We report the case of a 70-year-old female patient diagnosed with aortic insufficiency. Following a transcatheter aortic valve replacement, she underwent emergency aortic valve replacement under cardiopulmonary bypass on the subsequent day due to heart valve displacement. The postoperative diagnosis revealed TTP and symptomatic treatment involving plasma exchange was administered. After demonstrating steady improvement, the patient was eventually discharged.
Conclusion: Aortic valve replacement after TAVR is a high-risk procedure and increases susceptibility for developing secondary TTP. The diagnosis and treatment of secondary TPP is considerably challenging, and early diagnosis with symptomatic treatment including plasma exchange can increase patient survival.

This procedure is carried out via a full sternotomy using standard aortic and bicaval cannulations. For the aortic and pulmonary anastomoses, selective antegrade unilateral cerebral perfusion is used after cooling the body temperature to 26 °Celsius. A 12-mm Hancock conduit is interposed between the pulmonary artery and the proximal descending aorta using standard running suture techniques.

Background: The coexistence of transthyretin cardiac amyloidosis (ATTR-CA) and aortic stenosis (AS) is increasingly recognized, but the clinical consequences are unclear. We aimed to characterize clinical outcomes in AS plus ATTR-CA compared with only AS or ATTR-CA.
Methods And Results: In a retrospective cohort study, patients with AS only, ATTR-CA only, or AS plus ATTR-CA were identified using all-payer claims data (2015-2021).

Background: Patients with complex valvular heart disease (VHD) should be evaluated by a multidisciplinary heart team (HT). In low- and middle-income countries, referral practices are more variable, permitting any physician to refer patients directly to a cardiac surgeon without prior formal evaluation by a cardiologist with expertise in VHD.
Objectives: The goal of the study was to examine the demographics of VHD patients seen in a large heart valve center in a low- and middle-income country and to assess the impact of the multidisciplinary HT in patients referred for valve surgery.
