Insights

Cardiovascular surgery is increasing, with coronary artery bypass graft remaining common. However, procedures for heart valves and congenital heart disease are rising, with mortality rates higher than international benchmarks.

Area of Science:

  • Cardiology
  • Cardiovascular Surgery
  • Public Health

Background:

  • Advancements in percutaneous techniques, clinical treatment, and primary prevention are transforming cardiovascular surgery.
  • The Instituto do Coração (InCor-HCFMUSP) is a key tertiary reference center for cardiovascular procedures in Brazil.

Purpose of the Study:

  • To evaluate the incidence and mortality trends of heart surgeries performed at the Instituto do Coração (InCor-HCFMUSP) between 1984 and 2007.

Main Methods:

  • A retrospective analysis of cardiovascular surgery data from the Instituto do Coração database.
  • Examination of trends in main surgical procedures and associated mortality rates over a 24-year period.

Main Results:

  • A total of 71,305 heart surgeries were performed, averaging 2,971 annually.
  • Significant increases observed in heart valve procedures (36.7%) and congenital heart disease repair (50.8%) compared to the 1990s.
  • While overall mortality decreased slightly from 7.5% to 7.0%, elective procedure mortality is 4.9%, with specific rates for coronary artery bypass graft (4.8%), valve surgery (8.5%), and congenital heart disease repair (5.3%).

Conclusions:

  • Cardiovascular surgery volume continues to grow, with coronary artery bypass graft still the most frequent procedure.
  • There is a notable shift towards increased complexity in procedures, particularly for cardiac valves and congenital heart disease.
  • Mortality rates at this national reference center remain higher than international standards, indicating the high complexity of cases managed.

Anatomy of the Heart01:20

Anatomy of the Heart

The heart is a hollow, muscular organ approximately the size of a fist, consisting of four chambers. It is enclosed in the pericardium, a fibrous sac with two layers: the visceral and parietal pericardium, separated by a fluid-filled space containing serous fluid to reduce friction.
The heart has three layers: the innermost endocardium, the muscular myocardium, and the outer epicardium, all working together for optimal cardiac function.

Anatomy of the Heart01:27

Anatomy of the Heart

The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

Cardiac Catheterization II: Right Heart Catheterization

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
Anatomy of the Circulatory System02:03

Anatomy of the Circulatory System

The human circulatory system consists of blood, blood vessels that carry blood away from the heart, around the body, and back to the heart, and the heart itself, which acts as a central pump. The systemic circuit supplies blood to the whole body, the coronary circuit supplies blood to the heart, and the pulmonary circuit supplies blood flow between the heart and lungs.
Coronary Artery Disease II: Pathophysiology01:26

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...
