Aortic Regurgitation II: Clinical Features and Diagnostic Tests01:22

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
Atelectasis II: Pathophysiology01:10

Atelectasis II: Pathophysiology

Atelectasis develops when alveoli lose their air and collapse inward. Because lung tissue is naturally elastic, these air sacs shrink rather than remaining open. Collapsed alveoli are no longer ventilated, reducing their role in gas exchange. Blood flow may continue in these regions, creating a ventilation–perfusion mismatch. Clinical findings include decreased breath sounds, dullness to percussion, reduced chest expansion, and decreased tactile fremitus as sound transmission through collapsed...

Mitral Valve Prolapse I: Introduction

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...

Cardiovascular System Abnormal Findings II: Auscultation

Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

Mitral Stenosis I: Introduction01:22

Mitral Stenosis I: Introduction

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...
Aortic Regurgitation I: Introduction01:15

Aortic Regurgitation I: Introduction

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

Septoplasty effectively treats anterior septal deviation with contralateral alar collapse. This surgical approach improved nasal breathing and nostril width in most patients, offering a recommended solution.

Area of Science:

  • Otolaryngology
  • Rhinology
  • Surgical Anatomy

Background:

  • Septal deviation frequently co-occurs with conditions impairing nasal patency.
  • Anterior septal deviation and contralateral alar collapse represent a rare functional impairment.
  • Septoplasty alone may resolve this condition without external valve surgery.

Purpose of the Study:

  • To prospectively evaluate the efficacy of septoplasty in treating anterior septal deviation with contralateral alar collapse.
  • To determine if septoplasty is a sufficient treatment without external valve surgery.

Main Methods:

  • Prospective study of 12 patients with anterior septal deviation and contralateral alar collapse.
  • Subjective assessment of nasal breathing pre- and post-operatively (1 day and 6 months).

  • Objective measurement of alar-columellar distance on the collapsed side pre- and post-operatively.
  • Main Results:

    • All patients reported improved nasal breathing on the deviated side immediately after surgery.
    • Significant improvement in alar-columellar distance observed in most patients on the collapsed side.
    • Average improvement in alar-columellar distance was 4.54 mm at 6 months post-surgery.

    Conclusions:

    • Septoplasty is a suitable and recommended treatment for anterior septal deviation with simultaneous contralateral alar collapse.
    • The procedure effectively addresses nasal obstruction in these specific anatomical conditions.
    • No additional external valve surgery was necessary for the studied patient group.
