Summary
A patient developed a rare complication after mitral valve replacement: an iatrogenic left ventricular to right atrial communication, also known as a Gerbode-type defect. This shunt required surgical correction.
Area of Science:
- Cardiology
- Cardiac Surgery
- Medical Imaging
Background:
- Rheumatic mitral stenosis necessitates mitral valve replacement surgery.
- Post-operative complications can arise, impacting cardiac function and hemodynamics.
Observation:
- A 51-year-old woman presented with abdominal pain and edema one week after mitral valve replacement.
- Physical examination revealed a new holosystolic murmur.
- Transesophageal echocardiography demonstrated abnormal blood flow from the left ventricle to the right atrium.
Findings:
- A small defect in the membranous interventricular septum was identified, creating a left ventricular to right atrial communication.
- The condition was diagnosed as an iatrogenic Gerbode-type defect.
- Intraoperative findings confirmed the diagnosis of a surgically created ventricular septal defect.
Implications:
- Prompt diagnosis and surgical intervention are crucial for managing iatrogenic Gerbode-type defects.
- This case highlights the importance of vigilant post-operative monitoring for rare cardiac complications.
- Understanding and recognizing these defects can improve patient outcomes following cardiac surgery.

Mitral Regurgitation I: Introduction
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 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...
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.

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...
Chambers of the Heart
The human heart is a complex organ made up of four chambers: the right and left atria and the right and left ventricles. These internal chambers are separated by partitions known as the interatrial and interventricular septa. The exterior of the heart features a groove known as the coronary sulcus that demarcates the atria from the ventricles, while the anterior and posterior interventricular sulci distinguish between the two ventricles.
