Summary
Bioprostheses are effective for correcting acquired heart failures, particularly in elderly patients undergoing artificial circulation. This study highlights their high efficacy and suitability for mitral and aortic valve repair.
Area of Science:
- Cardiovascular Surgery
- Biomedical Engineering
- Clinical Medicine
Background:
- Acquired heart failure, especially mitral valve (MV) and aortic valve (AV) dysfunction, necessitates surgical intervention.
- Artificial blood circulation (cardiopulmonary bypass) is a critical component in cardiac surgeries for valve repair or replacement.
- The choice between bioprosthetic and mechanical prostheses involves considerations of efficacy, durability, and patient-specific factors.
Purpose of the Study:
- To evaluate the efficacy and applicability of bioprostheses for correcting acquired heart failures during artificial blood circulation.
- To compare the outcomes of bioprosthetic versus mechanical prostheses in patients with mitral and aortic valve failures.
- To assess the long-term stability and suitability of bioprostheses, especially in elderly patient populations.
Main Methods:
- Retrospective analysis of 235 patients with acquired mitral valve (MV) and aortic valve (AV) failures.
- Surgical intervention involving MV prosthesis in 89 patients and AV prosthesis in 146 patients.
- Implantation of bioprostheses in 94 patients and mechanical prostheses in 141 patients, with assessment of left heart morphometry and survival rates.
Main Results:
- Bioprosthetic application demonstrated high efficacy in correcting acquired heart failures.
- Analysis of left heart morphometry and survival indices indicated favorable outcomes with bioprostheses.
- The stability of positive postoperative results in the remote period supports the efficacy of bioprosthetic use.
Conclusions:
- Bioprostheses are highly effective for correcting acquired heart failures in patients requiring artificial blood circulation.
- The application of bioprostheses is expedient, particularly in aged patients, offering stable long-term results.
- Bioprosthetic devices represent a valuable option for mitral and aortic valve repair in specific patient cohorts.

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

3.7K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

01:27Heart Failure I: Introduction
903
Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...

Additional therapies for treating patients with heart failure (HF) may include procedural interventions, supplemental oxygen, the management of sleep disorders, and nutritional therapy.Procedural InterventionsImplantable Cardioverter-Defibrillator: For patients at risk of life-threatening arrhythmias due to severe left ventricular dysfunction, an Implantable Cardioverter-Defibrillator (ICD) can detect and terminate these arrhythmias, preventing sudden cardiac death and improving survival rates.

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...
