Abstract

Insights

High-volume mitral valve (MV) surgeons achieve better repair rates and lower mortality. Centralizing MV surgery may improve patient outcomes by ensuring procedures are performed by experienced, high-volume surgeons.

Area of Science:

  • Cardiovascular Surgery
  • Health Services Research

Background:

  • Surgeon volume is a potential determinant of patient outcomes in mitral valve (MV) surgery.
  • Existing literature suggests a link between surgeon experience and surgical success.

Purpose of the Study:

  • To systematically review published studies investigating the association between individual surgeon volume and outcomes in MV surgery.
  • To assess the impact of surgeon experience on mitral valve repair rates, mortality, and reoperation rates.

Main Methods:

  • A systematic literature search was conducted on PubMed up to November 19, 2020.
  • Seven retrospective cohort studies, totaling 158,488 patients, were included in the qualitative analysis.
  • Methodological quality was assessed using the Newcastle-Ottawa Scale (NOS).

Main Results:

  • Heterogeneous definitions of surgeon volume precluded data pooling.
  • Higher surgeon volume was significantly associated with improved mitral valve repair rates (OR = 1.25-5.5) and mortality (OR = 0.46-0.84).
  • Results for reoperation rates were inconsistent; a mean threshold of 30 MV surgeries per year was identified.

Conclusions:

  • Increased surgeon volume correlates with superior mitral valve repair rates and reduced mortality.
  • Mitral valve surgery should ideally be performed by high-volume surgeons.
  • Centralization of mitral valve surgery may be a necessary strategy to improve patient outcomes.

Mitral Stenosis III: Medical Management

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...

Mitral Regurgitation III: Medical Management

Mitral regurgitation (MR) is characterized by retrograde blood circulation from the left ventricle into the left atrium due to inadequate mitral valve closure. The severity of the condition, symptoms, and underlying cause determine treatment strategies.Monitoring and Pharmacological TreatmentPatients with mild to moderate MR typically do not need immediate intervention but regular monitoring to assess progression and guide treatment. Patients with mild MR should have an echocardiogram every 3-5...

Mitral Valve Prolapse II: Assessment and Management

IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...

Mitral Stenosis I: Introduction

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Mitral Regurgitation I: Introduction01:20

Mitral Regurgitation I: Introduction

Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

Mitral Valve Prolapse I: Introduction

IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...
