Interventional therapies for relief of obstruction in hypertrophic cardiomyopathy: discussion and proposed clinical...

Area of Science:

• Cardiology
• Genetics
• Internal Medicine

Background:

• Hypertrophic cardiomyopathy (HCM) is now recognized as more prevalent, affecting up to 1 in 300 individuals across all demographics.
• Increased awareness, advanced imaging, and specialized centers lead to earlier and more frequent clinical presentations of HCM.
• Patients present with varied symptoms, including heart failure, dyspnea, angina, syncope, and edema, and distinct anatomical variations like mid-ventricular obstruction or apical disease.

Purpose of the Study:

• To review interventional approaches for relieving obstruction in hypertrophic cardiomyopathy (HCM).
• To present a clinical algorithm for selecting between interventional and surgical approaches for HCM treatment.
• To highlight the evolving landscape of invasive treatment options for HCM.

Main Methods:

• Review of current interventional and surgical techniques for HCM obstruction relief.
• Analysis of clinical data and outcomes associated with different treatment modalities.
• Development and presentation of a decision-making algorithm for treatment selection.

Main Results:

• Both percutaneous and surgical interventions are available for the spectrum of HCM severity and anatomy.
• Treatment techniques and outcomes continue to improve with evolving experience.
• Advances allow for targeted and individualized treatment strategies for most HCM patients.

Conclusions:

• Interventional and surgical options provide effective treatment for hypertrophic cardiomyopathy (HCM).
• Personalized treatment algorithms can guide optimal selection between interventional and surgical approaches.
• Ongoing advancements promise further improvements in managing HCM obstruction and patient outcomes.
