Mitral Valve Prolapse I: Introduction01:27

Mitral Valve Prolapse I: Introduction

774
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...

Mitral Regurgitation I: Introduction01:20

Mitral Regurgitation I: Introduction

759
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 II: Assessment and Management

860
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: Introduction01:22

Mitral Stenosis I: Introduction

966
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...

Heart Valves

The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

Aortic Regurgitation I: Introduction01:15

Aortic Regurgitation I: Introduction

940
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Summary

Permanent pacemaker implantation after surgical aortic valve replacement is associated with longer hospital stays and specific patient factors. The incidence is low and compares favorably to transcatheter aortic valve implantation.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Biomedical Engineering

Background:

  • Permanent pacemaker implantation (PPI) is a potential complication following surgical aortic valve replacement (SAVR).
  • Patient selection and risk factors for conduction disorders significantly influence PPI rates.
  • Identifying these risk factors is crucial for optimizing patient outcomes and comparing SAVR with transcatheter aortic valve implantation (TAVI).

Purpose of the Study:

  • To identify risk criteria for PPI after SAVR.
  • To select a patient group for SAVR comparable to those undergoing TAVI.
  • To analyze factors influencing PPI and compare incidence rates with TAVI.

Main Methods:

  • Retrospective review of 994 patients undergoing isolated sutured aortic valve replacements from 2007 to 2015.
  • Comparison of demographics, hospital stay, preexisting conduction disorders, surgical technique, and etiology between patients with and without PPI.
  • Subgroup analysis comparing outcomes with reported TAVI data, focusing on degenerative valve disease and first redo procedures.

Main Results:

  • The overall incidence of PPI was 2.9%.
  • Factors associated with PPI included longer hospital stay, preexisting rhythm disorders, complex prosthetic endocarditis, and complex redo surgery.
  • Interrupted pledgetted sutures were more frequently used in the PPI group compared to continuous monofilament sutures.
  • In a subgroup analysis, PPI incidence was 2%, with preexisting rhythm disorders and suture technique remaining significant risk factors.

Conclusions:

  • PPI after SAVR is influenced by valve etiology, preexisting rhythm disorders, and the surgical suture technique.
  • The observed PPI incidence of 2% is favorable compared to the 5- to 10-fold higher rates reported for TAVI.
  • Cost-effectiveness analyses should consider PPI rates, and this complication should not be dismissed due to associated risks like endocarditis and mortality.
