Here, we provide a useful approach for studying the mechanism of right ventricular failure. A more convenient and efficient approach to pulmonary artery constriction is established using surgical instruments made inhouse. In addition, methods to evaluate the quality of this approach by echocardiography and catheterization are provided.

Source: Yong P. Chen, PhD, Department of Physics & Astronomy, College of Science, Purdue University, West Lafayette, IN This experiment will use inductive coils to demonstrate the concept of inductor and inductance. Magnetic induction will be demonstrated using a rod magnet inserted into or extracted away from the core of a coil to induce a transient electromotive force (emf) voltage in the coil, measured by a voltmeter. This experiment will also demonstrate the mutual inductance between...

The objectives of this experiment are to find the equivalent circuit parameters of a three-phase induction motor using the per-phase equivalent circuit and tests similar to those used in transformer characterization. In electrical engineering, an equivalent circuit (or theoretical circuit) can be determined for a given system. The equivalent circuit retains all characteristics of the original system,...

We present a protocol to induce and phenotype an acute right heart failure in a large animal model with chronic pulmonary hypertension. This model can be used to test therapeutic interventions, to develop right heart metrics or to improve the understanding of acute right heart failure pathophysiology.

FAQs
Increasing right ventricular afterload forces the ventricle to pump against greater resistance in the pulmonary circulation. Sustained pressure overload can drive ventricular remodeling, while worsening contractility limits forward performance and contributes to systemic venous congestion. This chain helps investigators connect an imposed cardiopulmonary stressor with the transition from compensated dysfunction toward clinically relevant failure.
Acute and chronic models answer different questions. A rapidly developing insult is useful for examining early changes in right-sided function, whereas prolonged pressure overload or pulmonary vascular injury supports analysis of remodeling and progressive deterioration. Comparing the two time courses can reveal which physiological or molecular markers accompany initial dysfunction and which are associated with decompensation.
The right ventricle and pulmonary circulation function as a coupled system, so altering pulmonary vascular load changes the work demanded from the ventricle. Studying that interaction helps researchers relate pulmonary pressure or vascular injury to reduced contractility, remodeling, and venous congestion. This context is especially important when interpreting whether a treatment improves ventricular performance or modifies the underlying cardiopulmonary burden.
Pulmonary artery constriction and pulmonary vascular injury create right ventricular stress through different experimental routes. Comparing them allows investigators to examine whether observed dysfunction, remodeling, or congestion is linked primarily to increased pulmonary afterload or to vascular injury. Such comparisons broaden interpretation of experimental results and help determine whether findings remain consistent across distinct causes of right-sided failure.
A controlled Rv Failure Induction protocol should specify the intended type of failure, the route used to increase right ventricular afterload, and whether the study targets acute or chronic progression. Investigators can then examine functional decline, remodeling, congestion, or markers of decompensation. Consistent control of induction conditions makes comparisons among treatments and experimental groups more informative.
These models can support evaluation of drugs, devices, and surgical strategies intended to address right-sided cardiac dysfunction or its cardiopulmonary drivers. Researchers can compare how an intervention affects ventricular performance, remodeling, congestion, or markers of decompensation. Using controlled experimental failure also helps distinguish responses during acute dysfunction from those emerging during chronic disease progression.
In medicine, these models provide a framework for studying causes and progression of right-sided failure while tracking physiological and molecular markers of decompensation. They also enable comparisons between different induction approaches and time courses. The resulting evidence can clarify cardiopulmonary disease mechanisms and inform development of treatments, devices, or surgical approaches for impaired right ventricular function.
