Summary
Lower heart transplant (HT) case volumes in hospitals correlate with higher in-hospital and long-term mortality. This suggests a need for minimum volume requirements to improve patient outcomes and resource allocation in HT procedures.
Area of Science:
- Cardiology
- Transplantation Surgery
- Health Services Research
Background:
- A known inverse relationship exists between institutional case-volume and mortality for complex, high-risk surgeries.
- Understanding this relationship is crucial for optimizing patient outcomes in heart transplantation (HT).
Purpose of the Study:
- To investigate the impact of hospital heart transplantation (HT) case-volume on patient outcomes within the Korean population.
- To analyze the association between institutional HT volume and both in-hospital and long-term mortality.
Main Methods:
- Analysis of adult HT procedures in Korea from 2007-2016 using National Health Insurance Service data.
- Hospitals were categorized into low-, medium-, and high-volume centers based on HT frequency.
- Statistical analysis of in-hospital and long-term mortality rates in relation to hospital volume.
Main Results:
- A total of 833 adult HTs were performed across 17 centers.
- In-hospital mortality rates were 3.7% (high-volume), 10.1% (medium-volume), and 18.6% (low-volume).
- Lower volume centers (medium and low) demonstrated significantly increased in-hospital mortality risk and worse long-term survival up to 10 years.
Conclusions:
- Lower institutional case-volume is significantly associated with increased in-hospital and long-term mortality after heart transplantation (HT).
- Implementing a minimum case-volume mandate for HT-performing hospitals may be necessary to enhance patient outcomes and optimize resource allocation.

01:27Anatomy of the Heart
119.5K
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.

30.6K
Calorimeters are useful to determine the heat released or absorbed by a chemical reaction. Coffee cup calorimeters are designed to operate at constant (atmospheric) pressure and are convenient to measure heat flow (or enthalpy change) accompanying processes that occur in solution at constant pressure. A different type of calorimeter that operates at constant volume, colloquially known as a bomb calorimeter, is used to measure the energy produced by reactions that yield large amounts of heat and...

01:20Volume of Distribution
1.2K
The apparent volume of distribution (Vd) is a crucial pharmacokinetic parameter representing the hypothetical body fluid volume into which a drug disperses. It is calculated based on the total amount of drug in the body (estimated from the administered dose and bioavailability) divided by the plasma drug concentration. The total amount of drug in the body does not directly refer to the dose given but is derived by accounting for absorption, distribution, metabolism, and excretion processes.

01:17Work Done During Volume Change
5.1K
In mechanics, work is done on an object when the force acting on it displaces the object. In thermodynamics, work done on a system can be estimated when the system's volume changes during any thermodynamic process.
Consider a gas confined to a cylinder fitted with a movable piston at one end. If the gas expands from volume V1 to volume V2, it exerts a force on the piston, such that the piston moves by a distance dr.
The work done by the gas on the piston can be expressed as

Respiratory volumes are crucial metrics, meticulously measured to quantify the air exchanged in and out of the lungs during various phases of the breathing cycle. These precise measurements are vital for assessing lung function, diagnosing respiratory conditions, and monitoring overall respiratory health. Each parameter provides specific insights into the mechanics of breathing and the functional capacity of the lungs.

01:27Regulation of Stroke Volume
4.8K
The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
