AI Article Synopsis

  • Secondary mitral regurgitation (SMR) increases the risk of mortality and heart failure hospitalizations, necessitating a collaborative approach for patient management.
  • While guideline-directed medical therapies are essential, some patients experience persistent SMR, leading to the adoption of transcatheter edge-to-edge repair (TEER) to enhance survival.
  • Advancements in technology and operator skills have improved the safety and efficacy of TEER, with ongoing research into new devices offering additional treatment options for patients who aren't candidates for TEER.

Article Abstract

Secondary mitral regurgitation (SMR) is associated with increased mortality and heart failure hospitalizations. The management of heart failure patients with SMR is complex and requires a multidisciplinary Heart Team approach. Guideline-directed medical therapies remain fundamental, yet in a proportion of patients SMR persists. In the past decade, transcatheter edge-to-edge repair (TEER) has been shown to improve survival in patients with SMR who remain symptomatic despite medical therapy. Technical advancements across newer generations of devices, improved imaging, and greater operator expertise have collectively contributed to the increased safety and efficacy of this procedure over time. Various emerging transcatheter mitral valve repair and replacement devices are currently under investigation and may offer superior, complementary or synergistic treatment options in patients ineligible for TEER. This review provides a state-of-the-art overview regarding the diagnosis of SMR, and currently available transcatheter mitral valve interventions and describes a contemporary approach to the management of SMR.

Background: Cancer-targeted therapies are progressively pivotal in oncological care. Observational studies underscore the emergence of cancer therapy-related cardiovascular toxicity (CTR-CVT), impacting patient outcomes. We aimed to investigate the causal relationship between different types of cancer-targeted therapies and cardiovascular disease (CVD) outcomes through a two-sample Mendelian randomization (MR) study.

Hypothesis And Background: As the incidence of reverse total shoulder arthroplasty (RTSA) continues to rise, better understanding of the long-term risks and complications is necessary to determine the best choice of implant. The majority (75%) of RTSA performed in New Zealand use either SMR (Systema Multiplana Randelli, Lima-LTO, Italy) or Delta Xtend (DePuy Synthes, USA). The aim of this registry-based study was to compare implant survival, risk of revision and reasons for revision between the two most frequently used RTSA prostheses: SMR and Delta Xtend.

Structured medication reviews (SMRs) were introduced into the National Health Service (NHS) Primary Care to support the delivery of the NHS Long-Term Plan for medicines optimization. SMRs improve the quality of care, reduce harm and offer value for money. However, evidence to support SMRs for patients with chronic kidney disease (CKD) stage G4-5D with elevated risk of cardiovascular disease and premature mortality is unknown.

Background: Although thyroid cancer is associated with low mortality rates, significant racial disparities in thyroid cancer outcomes have not been adequately studied in Asia. Moreover, the Asian population consists of different ethnic groups that are not homogeneous. This study aimed to perform a population-based analysis of survival outcomes and prognostic factors in thyroid cancer patients.

Introduction: Non-cancer deaths are now becoming a significant threat to the health of cancer patients. Death from stomach and duodenal ulcer is linked to cancer due to the side effects of treatment and its pathogenesis. However, guidelines for identifying cancer patients at the highest risk of death from stomach and duodenal ulcer remain unclear.
