[Experience in Obstructive Hyperthrophic Myocardiopathy Surgery at a National Reference Center]

Area of Science:

• Cardiovascular Surgery
• Cardiology
• Medical Research

Context:

• Hypertrophic obstructive cardiomyopathy (HOC) presents significant clinical challenges.
• Effective treatment strategies for HOC are crucial for improving patient outcomes.
• Surgical intervention is a key therapeutic option for managing HOC.

Purpose:

• To evaluate the clinical characteristics and surgical outcomes of hypertrophic obstructive cardiomyopathy (HOC).
• To demonstrate the efficacy of surgical treatment for HOC at a national reference institute.
• To analyze the postoperative evolution of symptomatology, functional class, left ventricular outflow tract gradient (LVOTG), and mitral regurgitation (MR) in HOC patients.

Summary:

• A retrospective case series analyzed 13 patients with HOC undergoing septal myectomy.
• Pre-surgery, 85% of patients were in functional class III-IV with severe mitral regurgitation (MR) and a mean LVOTG of 111 mmHg.
• Post-surgery, 69% improved to functional class I, 92% had minimal MR, and LVOTG reduced to 16 mmHg.

Impact:

• Surgical treatment for HOC yields positive results, improving functional class and reducing LVOTG and MR.
• Simultaneous mitral valve surgery enhances treatment efficacy in select HOC cases.
• This study highlights the success of addressing both myocardial and valve components in HOC management.
