Article Abstract
Aim of this study was to compare early clinical and hemodynamic outcomes of Intuity and ME bioprostheses. A propensity score weighting approach was performed. Preoperative variables were defined according to EuroSCORE criteria and postoperative complications according to VARC-2 definitions. We evaluated 375 patients who underwent SAVR with the 2 study devices. Intuity and ME were implanted in 252 (67.2%) and in 123 (32.8%) patients, respectively. There were no differences in terms of postoperative complications, including mortality (1% in each group; OR 0.46[0.05;4.21]). The incidence of pace-maker implantation was 6% and 5% in Intuity and ME groups, respectively (OR 0.53[0.27;1.07]). Intuity showed significantly lower gradients (Median mean gradients: 9mmHg vs 14mmHg, P<0.001), larger effective orifice area index (1.13cm2/m2 vs 1cm2/m2, P=0.007) and lower incidence of patient-prosthesis mismatch (7.1% vs 22.8%, P=0.006). The RD Intuity provides similar early clinical outcomes but shows significantly better hemodynamic performance compared to the ME valve.

Cardiac arrest (CA) is a critical condition in the field of cardiovascular medicine. Despite successful resuscitation, patients continue to have a high mortality rate, largely due to post CA syndrome (PCAS). However, the injury and pathophysiological mechanisms underlying PCAS remain unclear.

Kommerell's diverticulum (KD) combined with a right-sided aortic arch (RAA) and an aberrant left subclavian artery (ALSA) is a rare congenital vascular anomaly causing significant compressive dysphagia. Treatment options, including open surgery, thoracic endovascular aortic repair and hybrid approaches, are debated due to anatomical complexities. We report a 48-year-old female with dysphagia from symptomatic KD, RAA and ALSA, clearly delineated by preoperative computed tomography angiography.

Complete detachment of the aortic root following a Bentall procedure is an exceptionally rare complication. The vast majority of reported cases are secondary to prosthetic valve endocarditis or underlying vasculitis. Currently, the most reliable treatment for aortic root dehiscence-particularly in the context of prosthetic valve endocarditis-is repeat root replacement, typically via a second Bentall procedure or with the use of a homograft or allograft.

Background: Postoperative complications significantly impact outcomes in head and neck free-flap reconstruction. The comprehensive complication index (CCI) offers a continuous measure of complication burden but is rarely applied in head and neck surgery compared to the Clavien-Dindo Classification (CDC).
Methods: This retrospective study analyzed 354 patients who underwent head and neck free-flap reconstruction.

Background: Fontan-associated liver disease can progress to advanced fibrosis, raising the potential need for combined heart-liver transplantation (CHLT) in selected patients. However, the benefits of CHLT over isolated orthotopic heart transplantation (HT), particularly in terms of mortality, remain uncertain. In this systematic review, we compared mortality outcomes following CHLT versus HT in patients with Fontan circulation, with the aim of supporting clinical decision-making.
