Aortic Regurgitation III: Medical Management

24
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Aortic Regurgitation I: Introduction

10
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Summary

Valve-sparing root replacement (VSRR) offers good outcomes, but survival decreases with age over 61 and comorbidities. Valve-related complication-free survival remains favorable across age groups.

Area of Science:

  • Cardiovascular Surgery
  • Aortic Valve Surgery
  • Aortic Root Replacement

Background:

  • Valve-sparing root replacement (VSRR) is linked to favorable survival and low valve-related complications (VRCs).
  • The impact of patient comorbidity and age on VSRR outcomes requires further investigation.

Purpose of the Study:

  • To analyze survival rates and the frequency of VRCs after VSRR.
  • To assess the influence of patient comorbidity and age on VSRR outcomes.

Main Methods:

  • A cohort of 1156 patients undergoing VSRR for bicuspid or tricuspid aortic valves between 1995 and 2021.
  • Analysis of survival and VRCs based on patient comorbidity and age at surgery, with ROC analysis to determine age cutoff.
  • Mean follow-up of 6.7 years with 95% completeness.

Main Results:

  • Mean 15-year survival was 74.7%. Deceased patients were older and had more comorbidities (e.g., coronary artery disease).
  • Age over 61 years was the sole significant predictor of mortality (P < .001).
  • 15-year survival was 87.1% for patients <61 years vs. 55.3% for patients >61 years. VRC-free survival at 15 years was 66.8% overall, with higher rates in younger patients.

Conclusions:

  • VSRR demonstrates excellent durability with a low incidence of VRCs.
  • Patient age >61 years and comorbidities, particularly coronary artery disease, are associated with decreased survival.
  • Despite age-related survival differences, VSRR provides good freedom from valve-related complications.
