We present the case of an 85-year-old woman diagnosed with severe aortic stenosis, porcelain aorta, and a small aortic annulus (17.3 mm), who underwent successful transfemoral transcatheter aortic valve implantation (TAVI) with a 20-mm Edwards SAPIEN XT valve using the NovaFlex+ delivery system. At 1-month follow-up the patient was in NYHA functional class I, and Doppler echocardiography showed a mean residual gradient of 15 mm Hg and trivial paravalvular aortic regurgitation. This case, which shows for the first time the feasibility of TAVI with a 20-mm valve, opens a new avenue for the challenging treatment of patients with aortic stenosis and a small aortic annulus.

Williams Syndrome (WS) is a rare neurodevelopmental disorder with a prevalence of 1 in 7500 to 1 in 20,000 individuals, caused by a microdeletion in chromosome 7q11.23. Despite its distinctive clinical features, the underlying metabolic alterations remain largely unexplored.

Hypertrophic cardiomyopathy (HCM) afflicts humans, cats, pigs, and rhesus macaques. Disease sequelae include congestive heart failure, thromboembolism, and sudden cardiac death (SCD). Sarcomeric mutations explain some human and cat cases, however, the molecular basis in rhesus macaques remains unknown.

Background/purpose: Transcatheter aortic valve replacement (TAVR) with ACURATE neo2 showed better hemodynamic outcomes by mitigating paravalvular leakage (PVL) compared with ACURATE neo, and revealed promising one-year outcomes in single-arm studies. However, studies comparing the hemodynamic and clinical outcomes of the two valves are still scarce. Therefore, this study aimed to compare the one-year hemodynamic and clinical outcomes between the neo2 and neo.

Introduction: This study aimed to compare the long-term outcomes in a propensity matched population receiving either minimally invasive direct coronary artery bypass (MIDCAB) using left internal thoracic artery (LITA) to the left anterior descending artery (LAD) or percutaneous coronary intervention using second generation everolismus-eluting stents (DES-PCI) in patients treated for isolated proximal LAD stenosis.
Methods: Between January 2012 and December 2017, 421 patients with a nonemergency status undergoing primary isolated proximal LAD revascularization were retrospectively analyzed and were divided into two groups: 111 patients receiving MIDCAB LITA to LAD and 310 patients receiving DES-PCI. Propensity score matching selected 111 pairs and both groups were comparable for all baseline characteristics and well balanced.
