Summary
Eccentric occlusion is a safe and feasible treatment for sub-arterial ventricular septal defects (VSDs). Careful patient selection and management ensure successful outcomes with minimal complications.
Area of Science:
- Cardiology
- Medical Devices
- Surgical Innovation
Background:
- Sub-arterial ventricular septal defects (VSDs) pose treatment challenges.
- Minimally invasive techniques are increasingly explored for VSD closure.
Purpose of the Study:
- To evaluate the safety and effectiveness of eccentric occlusion for sub-arterial VSDs.
- To analyze failure modes, indications, and complications associated with this technique.
Main Methods:
- Retrospective study of 105 patients undergoing transthoracic sub-arterial VSD occlusion.
- Analysis of device implantation success rates, reasons for failure, and perioperative management.
Main Results:
- Successful occlusion achieved in 74.2% of cases.
- Common failure reasons included aortic regurgitation, residual shunt, and device malposition.
- No device displacement, shedding, or arrhythmias observed during follow-up.
Conclusions:
- Eccentric occlusion is a secure and feasible option for sub-arterial VSD treatment.
- Strict adherence to surgical indications, device selection, and perioperative care is crucial for success.

01:15Aortic Regurgitation I: Introduction
10
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...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

01:20Mitral Regurgitation I: Introduction
15
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...

01:22Mitral Stenosis I: Introduction
15
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...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
