Introduction to Valvular Heart Disease Guidelines
Valvular heart disease (VHD) is a significant contributor to morbidity and mortality, and its management has undergone a paradigm shift with the emergence of novel transcatheter technologies 1. The guidelines for VHD emphasize the importance of timely intervention to optimize long-term outcomes.
Diagnosis and Assessment
The diagnosis and assessment of VHD involve a comprehensive evaluation of the patient's symptoms, medical history, and imaging studies. Recent advances in imaging and transcatheter techniques have improved the diagnosis and management of VHD 2. Artificial intelligence and digital methods are enhancing screening, diagnosis, and planning procedures, and the integration of imaging and clinical data is improving the classification of VHD severity.
Treatment Options
The treatment options for VHD include medical therapy, percutaneous interventions, and surgical interventions. The choice of treatment depends on the severity of the valve disease, the presence of symptoms, and the patient's overall health status. Transcatheter aortic valve implantation (TAVI) is not recommended for asymptomatic severe aortic stenosis, although this may change in the future 3. Mitral balloon valvotomy is a viable option for patients with mitral stenosis, and early intervention may be beneficial in preventing atrial fibrillation, embolic events, and pulmonary hypertension.
Timing of Intervention
The timing of intervention in asymptomatic patients with VHD is a constantly changing threshold that depends on the severity of the valve disease and the safety, efficacy, and long-term durability of treatment options 3. The guidelines recommend careful individual weighing of the potential benefits against the risk of intervention and its long-term consequences. Emerging risk markers, such as very severe valve obstruction, elevated serum natriuretic peptide levels, and imaging evidence of myocardial fibrosis or increased extracellular myocardial volume, may guide decision-making.
Management of Acute Decompensated Valvular Disease
Acute decompensated valvular disease is a complex and challenging condition that requires prompt diagnosis and management. The guidelines highlight the importance of multidisciplinary Heart Teams in managing critically ill patients with decompensated valvular disease 4. Medical and percutaneous interventional therapies may be limited, and surgical risk can be prohibitive. High-quality evidence to direct management of acute valvular disorders is lacking, and societal guidelines largely do not address treatment options for critically ill patients with decompensated valvular disease.
Comparison of Guidelines
The recent updates to the ACC/AHA and ESC guidelines for the management of VHD contain significant similarities and differences 5. The guidelines provide new recommendations on the use of percutaneous treatments, the indications for intervention in asymptomatic VHD, and perioperative bridging therapies. However, there remain significant gaps in the role of biomarkers in VHD and the long-term outcomes of novel oral anticoagulants (NOACs) and transcatheter therapies.
Conclusion
The guidelines for valvular heart disease emphasize the importance of timely intervention, careful individual weighing of the potential benefits against the risk of intervention, and the use of emerging risk markers to guide decision-making. The management of VHD requires a multidisciplinary approach, and high-quality evidence is needed to direct management of acute valvular disorders. Recent advances in imaging and transcatheter techniques have improved the diagnosis and management of VHD, and artificial intelligence and digital methods are enhancing screening, diagnosis, and planning procedures.
Treatment
- Medical therapy: used to manage symptoms and slow disease progression
- Percutaneous interventions: used to treat valve disease, such as TAVI and mitral balloon valvotomy
- Surgical interventions: used to repair or replace the affected valve
