EValuating the Effect of periopeRaTIve empaGliflOzin on cardiac surgery associated acute kidney injury: rationale and design of the VERTIGO study.

Background: Cardiac surgery-associated acute kidney injury (CSA-AKI) is a serious complication in patients undergoing cardiac surgery with extracorporeal circulation (ECC) that increases postoperative complications and mortality. CSA-AKI develops due to a combination of patient- and surgery-related risk factors that enhance renal ischemia-reperfusion injury. Sodium-glucose cotransporter 2 inhibitors (SGLT2i) such as empagliflozin reduce renal glucose reabsorption, improving tubulo-glomerular feedback, reducing inflammation and decreasing intraglomerular pressure.

Durability of bioprosthetic aortic valve replacement in patients under the age of 60 years - 1-year follow-up from the prospective INDURE registry.

Methods: The INSPIRIS RESILIA Durability Registry is a prospective, multicentre registry to assess clinical outcomes of patients <60 years. Patients with planned SAVR with or without concomitant replacement of the ascending aorta and/or coronary bypass surgery were included.

Molecular mechanisms of postoperative atrial fibrillation in patients with obstructive sleep apnea.

Obstructive sleep apnea (OSA) promotes atrial remodeling and fibrosis, providing a substrate for atrial fibrillation (AF). Herein, we investigate the pathophysiological mechanisms of AF in association with OSA in a cohort of cardiac surgery patients. A prospective study including patients undergoing cardiac surgery.

Extreme In Situ Liver Surgery Under Total Vascular Exclusion with Right Hepatic Vein and Inferior Vena Cava Grafts for an Intrahepatic Cholangiocarcinoma.

In this multimedia article, we demonstrate an extreme in situ liver surgery under total vascular exclusion with right hepatic vein and inferior vena cava grafts for an intrahepatic cholangiocarcinoma in a centre with experience in highly complex hepatobiliary surgery and liver transplantation. This surgical approach after neoadjuvant chemotherapy provides an opportunity for surgical salvage in patients with large tumors invading the hepatocaval confluence. This patient was considered unresectable at another hospital and referred to our unit.

Contact pathway in surgical and transcatheter aortic valve replacement.

Background: Aortic valve replacement is the gold standard treatment for severe symptomatic aortic stenosis, but thrombosis of bioprosthetic valves (PVT) remains a concern.

Objective: To analyze the factors involved in the contact pathway during aortic valve replacement and to assess their impact on the development of thromboembolic complications.

Methods: The study was conducted in 232 consecutive patients who underwent: transcatheter aortic valve replacement (TAVR, = 155), and surgical valve replacement (SAVR, = 77) (MUVITAVI project).

Life expectancy after surgical aortic valve replacement for low-gradient aortic stenosis with preserved ejection fraction.

Introduction And Objectives: Surgical aortic valve replacement (SAVR) can modify the natural history of severe aortic stenosis (SAS). However, compared with the general population, these patients have a loss of life expectancy. The life expectancy of patients who undergo SAVR due to low-gradient SAS with preserved left ventricular ejection fraction (LVEF) is unknown.

Accessory left atrial cords: A case report and literature review.

Introduction: Accessory left atrial cords are fibroelastic structures found in the left atrium. Left atrial cords may be associated with mitral valve disease, atrial fibrillation, stroke, and other congenital left-side anomalies.

Methods: We presented the case of a man with severe Mitral Regurgitation and two accessories left atrial cords attached to P2 scallop by a single tendon and performed a literature review using PUBMED/MEDLINE, Web of Science, and EMBASE databases on December 4, 2021.

Life expectancy after aortic valve replacement in young patients.

Introduction And Objectives: In young patients with severe aortic stenosis, it is unknown whether their life expectancy restored after aortic valve replacement (AVR) is unknown.

Methods: We analyzed all patients aged between 50 and 65 years who underwent isolated AVR in 27 Spanish centers during an 18-year period. We compared observed and expected survival at 15 years of follow-up.

Differences in life expectancy between men and women after aortic valve replacement.

Objectives: Some researchers have observed an increased number of deaths during the follow-up of young patients who undergo aortic valve replacement due to severe aortic stenosis, suggesting that this procedure does not restore their life expectancy. Our goal was to confirm these findings and explore sex-based differences.

Methods: All patients between 50 and 65 years of age who underwent isolated aortic valve replacement in 27 Spanish centres during an 18-year period were included.

Risk Factors for Postoperative Pacemaker Implantation After Rapid Deployment Aortic Valve Replacement: Results from the RADAR Registry.

Introduction: Rapid deployment aortic valve replacement has been recently introduced in clinical practice. Different studies have reported a significant reduction in surgical times with excellent hemodynamic profiles and short-term results. However, an increase in permanent pacemaker requirements compared with conventional aortic valve replacement has been described.

Spanish experience with heart transplants from controlled donation after the circulatory determination of death using thoraco-abdominal normothermic regional perfusion and cold storage.

Heart transplantation from controlled donation after the circulatory determination of death (cDCDD) may help to increase the availability of hearts for transplantation. During 2020, four heart transplants were performed at three different Spanish hospitals based on the use of thoraco-abdominal normothermic regional perfusion (TA-NRP) followed by cold storage (CS). All donors were young adults <45 years.

Durability of bioprosthetic aortic valves in patients under the age of 60 years - rationale and design of the international INDURE registry.

Background: There is an ever-growing number of patients requiring aortic valve replacement (AVR). Limited data is available on the long-term outcomes and structural integrity of bioprosthetic valves in younger patients undergoing surgical AVR.

Methods: The INSPIRIS RESILIA Durability Registry (INDURE) is a prospective, open-label, multicentre, international registry with a follow-up of 5 years to assess clinical outcomes of patients younger than 60 years who undergo surgical AVR using the INSPIRIS RESILIA aortic valve.

Incidence and causes of pacemaker implantation during postoperative period of aortic valve replacement with rapid deployment prosthesis.

Background: Aortic stenosis is currently the most frequently occurring valve pathology. Developments, such as transcatheter prostheses and rapid deployment prostheses, allow for the offer of a valve replacement to higher risk patients, but these techniques are linked with a higher need for a permanent pacemaker during the immediate postoperative period.

Methods: We studied the incidence and the factors associated with permanent pacemaker implantation after aortic valve replacement with Edwards Intuity rapid deployment prosthesis.

Rationale and design of a multicentre, prospective, randomised, controlled clinical trial to evaluate the efficacy of the adipose graft transposition procedure in patients with a myocardial scar: the AGTP II trial.

Introduction: Cardiac adipose tissue is a source of progenitor cells with regenerative capacity. Studies in rodents demonstrated that the intramyocardial delivery of cells derived from this tissue improves cardiac function after myocardial infarction (MI). We developed a new reparative approach for damaged myocardium that integrates the regenerative properties of cardiac adipose tissue with tissue engineering.

Von Willebrand factor is associated with atrial fibrillation development in ischaemic patients after cardiac surgery.

Aims: Atrial fibrillation (AF) is associated with an increased morbidity and mortality after cardiac surgery. Von Willebrand factor (vWF) has been proposed as a biomarker of endothelial damage/dysfunction. We hypothesized that vWF levels could be used as valuable biomarker for AF occurrence after cardiac surgery.

The impact of calcium volume and distribution in aortic root injury related to balloon-expandable transcatheter aortic valve replacement.

Background: A detailed assessment of calcium within the aortic root may provide important additional information regarding the risk of aortic root injury during transcatheter heart valve replacement (TAVR).

Objective: We sought to delineate the effect of calcium volume and distribution on aortic root injury during TAVR.

Methods: Thirty-three patients experiencing aortic root injury during TAVR with a balloon-expandable valve were compared with a control group of 153 consecutive TAVR patients without aortic root injury (as assessed by post-TAVR multidetector CT).

TWEAK and NT-proBNP levels predict exercise capacity in hypertrophic cardiomyopathy.

Background: Hypertrophic cardiomyopathy (HCM) is characterized by inappropriate hypertrophy, myocyte disarray and increased interstitial fibrosis. The tumour necrosis factor-like weak inducer of apoptosis (TWEAK) is a cell surface cytokine with biological activities including stimulation of cell growth, induction of inflammatory cytokines and stimulation of apoptosis. There are controversial data about the potential role of TWEAK in different cardiovascular pathologies.
