Background: Left ventricular (LV) end-systolic enlargement in severe degenerative mitral-regurgitation (MR) is a class I surgical trigger. Whether it occurs disproportionately to less-than-severe MR due to mitral valve prolapse and is associated with mortality are unknown. We aimed to analyze prevalence and association with survival of disproportionate LV enlargement in less-than-severe MR.

Background: Management of degenerated aortic bioprostheses through valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) or redo surgical aortic valve replacement (Re-SAVR) shows similar short-term safety and efficacy. However, long-term survival and haemodynamic performance data are limited.

Aim: To compare clinical characteristics, haemodynamics and outcomes at 3 years between ViV-TAVR and Re-SAVR techniques.

Purpose: Whether skin disinfection of the surgical site using chlorhexidine-alcohol is superior to povidone-iodine-alcohol in reducing reoperation and surgical site infection rates after major cardiac surgery remains unclear.

Methods: CLEAN 2 was a multicenter, open-label, randomized, two-arm, assessor-blind, superiority trial conducted in eight French hospitals. We randomly assigned adult patients undergoing major heart or aortic surgery via sternotomy, with or without saphenous vein or radial artery harvesting, to have all surgical sites disinfected with either 2% chlorhexidine-alcohol or 5% povidone-iodine-alcohol.

Background: Isolated posterior leaflet mitral valve prolapse (PostMVP), a common form of MVP, often referred as fibroelastic deficiency, is considered a degenerative disease. PostMVP patients are usually asymptomatic and often undiagnosed until chordal rupture. The present study aims to characterize familial PostMVP phenotype and familial recurrence, its genetic background, and the pathophysiological processes involved.

Article Synopsis
  • The study evaluates the use of a specialized aortic root endograft for treating acute type A aortic dissections (ATAAD) and proposes a new classification for aortic tears.
  • With a high perioperative mortality rate of 12% to 20%, traditional surgical options are being compared to the Endobentall approach, which has only seen limited documentation in case reports.
  • Out of 250 CT scans reviewed, 116 patients were analyzed, revealing that 63.7% were eligible for the Endobentall procedure, increasing to 73.3% under extended criteria, with most cases qualifying for the fenestrated version.

Article Synopsis
  • The study aimed to explore differences in characteristics and 2-year outcomes after surgical aortic valve replacement (SAVR) between males and females, using data from two registries involving 933 patients.
  • Females had certain clinical differences such as lower body mass index, higher surgical risk scores, and smaller valves compared to males, but these disparities largely disappeared after adjusting for similar baseline characteristics.
  • Ultimately, despite a higher initial surgical risk profile, both sexes had comparable outcomes 2 years post-SAVR, indicating no significant differences in overall results based on sex.

Article Synopsis
  • Aortic valve calcification (AVC) was studied in patients with bioprosthetic valves to assess its impact on patient prognosis.
  • In a study of 361 patients who had valve replacements, AVC was found to be significantly higher in those with structural valve degeneration (SVD).
  • The results indicate that AVC greater than 100 Agatston units is correlated with worse health outcomes and increased risk of mortality and cardiovascular events, making CT scans a valuable tool for evaluation.

Structural valve deterioration (SVD) of bioprosthetic heart valves (BHVs) has great clinical and economic consequences. Notably, immunity against BHVs plays a major role in SVD, especially when implanted in young and middle-aged patients. However, the complex pathogenesis of SVD remains to be fully characterized, and analyses of commercial BHVs in standardized-preclinical settings are needed for further advancement.

Background: Structural changes and myocardial fibrosis quantification by cardiac imaging have become increasingly important to predict cardiovascular events in patients with mitral valve prolapse (MVP). In this setting, it is likely that an unsupervised approach using machine learning may improve their risk assessment.

Objectives: This study used machine learning to improve the risk assessment of patients with MVP by identifying echocardiographic phenotypes and their respective association with myocardial fibrosis and prognosis.

Background: Long-term outcomes after acute type A aortic dissection (ATAAD) are related to remodelling of the descending thoracic aorta and aortic reinterventions. We compared the impact of an extensive repair at the index procedure using the Frozen Elephant Trunk (FET) technique, versus a conventional arch repair, on long-term remodelling of the descending thoracic and reintervention related to the aorta.

Methods: Consecutive patients who underwent conventional arch repair (conventional group) or FET repair (FET group) for an ATAAD from September 2018 to November 2021 were included.

Aims: Indications for surgery in patients with degenerative mitral regurgitation (DMR) are increasingly liberal in all clinical guidelines but the role of secondary outcome determinants (left atrial volume index ≥60 mL/m2, atrial fibrillation, pulmonary artery systolic pressure ≥50 mmHg and moderate to severe tricuspid regurgitation) and their impact on post-operative outcome remain disputed. Whether these secondary outcome markers are just reflective of the DMR severity or intrinsically affect survival after DMR surgery is uncertain and may have critical importance in the management of patients with DMR. To address these gaps of knowledge the present study gathered a large cohort of patients with quantified DMR, accounted for the number of secondary outcome markers and examined their independent impact on survival after surgical correction of the DMR.
