INTRODUCTION Aortic root (AoR) dilation is associated with cardiac damage and higher cardiovascular risk. Cardiovascular disease is the most common cause of death in patients after kidney transplantation (KTx ). OBJECTIVES The aim of this study was to assess the prevalence of enlarged AoR diameter in KTx recipients. Patients with bicuspid aortic valve, significant valvular disease, or evidence of connective tissue disorder were excluded. PATIENTS AND METHODS A total of 87 KTx recipients were divided into 2 groups depending on immunosuppressive regimen: 41 patients receiving mammalian target of rapamycin inhibitors (mTORi) and 46 patients treated with calcineurin inhibitors (CNIs). In all patients, echocardiography was performed, laboratory and clinical markers of cardiovascular risk were assessed, and the AoR diameter was calculated. RESULTS There were no differences between groups in age, sex, body surface area, body mass index, frequency of diabetes, hypertension, dyslipidemia, time after replacement therapy, creatinine levels, and estimated glomerular filtration rate. In the CNI group, the observed and calculated AoR diameters were similar (P = 0.8). In the mTORi group, the observed AoR diameter was higher than the calculated one (P = 0.002). The concentric and eccentric left ventricular hypertrophy was similar in both groups (P = 0.12 and P = 0.69, respectively). In the stepwise regression analysis, the AoR diameter was associated with body surface area and mTORi treatment. CONCLUSIONS KTx recipients have a high prevalence of AoR dilation. Immunosuppressive regimen based on mTORi increases the incidence of AoR enlargement.

Bicuspid aortic valve (BAV) is recognized as a syndrome including aortic valve diseases and aortic wall alterations, such as aortic dilatation, dissection and rupture, but also coronary atherosclerosis. The current evidence, although partially controversial, suggests that several molecular mechanisms promoting atherosclerosis are activated in BAV patients and are involved in the progression of the related diseases, from aortic stenosis to aortopathies, along with altered hemodynamics. Among these factors, dyslipidemia (i.e., high LDL cholesterol, high lipoprotein (a)) and the activation of specific pro-inflammatory pathways (nucleotide-binding oligomerization domain-like receptor containing pyrin domain 3 inflammasome and Toll-like receptor 4) appear to play a pivotal role in the progression of BAV-associated diseases. The further elucidation of such molecular mechanisms may lead to a better and personalized prognosis and follow-up for BAV patients and suggest novel pharmacological approaches to prevent disease progression.

A 79-year-old man with a history of partial resection of the lung and the bladder due to cancer, hypertension, dyslipidemia, and heart failure, underwent transcatheter aortic valve replacement with a SAPIEN 3 (S3) valve (Edwards Lifesciences, Irvine, CA, USA). Preprocedural examination showed a bicuspid aortic valve and severe calcification of the leaflets. Computed tomography showed great tortuosity of the descending aorta. A 29-mm S3 valve prosthesis was advanced into the aorta, but a high degree of resistance was encountered in the middle of the descending aorta. The prosthesis was advanced to the level of aortic valve and an attempt was made to deploy the valve. However, the valve balloon did not expand. A balloon rupture was suspected. The balloon catheter was pulled back into the eSheath (Edwards Lifesciences), and the catheter and eSheath were removed together. Rupture of the balloon was confirmed. A new eSheath and prosthesis were prepared, with delivery supported with a Lunderquist guidewire (Cook Medical, Bloomington, IN, USA). The valve alignment procedure was performed in a straighter portion of the descending aorta. The new 29-mm S3 valve was then successfully implanted. <Learning objective: Rupture of the balloon during transcatheter aortic valve replacement is a rare, potentially fatal complication. A case of balloon rupture during a valve alignment procedure with successful retrieval is reported along with a review of the complication involved.>.
