Summary
The Konno procedure successfully treated a 2-year-old girl
Area of Science:
- Pediatric Cardiac Surgery
- Congenital Heart Disease
- Interrupted Aortic Arch Repair
Background:
- A 2-year-old girl with interrupted aortic arch and left ventricular outflow tract stenosis initially underwent the Yasui procedure.
- This involved a Damus-Kaye-Stansel anastomosis, a common palliative approach for complex congenital heart defects.
Observation:
- The patient developed restenosis of the left ventricular outflow tract and neoaortic regurgitation.
- This complication was attributed to a narrowed ventricular septal defect and the original pulmonary valve.
Findings:
- A repeat Konno procedure was performed, involving removal of the Damus-Kaye-Stansel anastomosis.
- The surgery included right ventricular outflow tract reconstruction and ventricular septal defect closure.
- Postoperative follow-up showed no recurrence of left ventricular outflow tract restenosis.
Implications:
- The Konno procedure is an effective treatment for complex left ventricular outflow tract obstruction after initial palliative surgery.
- This case highlights the importance of addressing VSD and neoaortic valve function during reinterventions.
- Successful surgical management can prevent further complications in pediatric patients with interrupted aortic arch.

71
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

01:15Aortic Regurgitation I: Introduction
75
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...

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...

83
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 stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...

A nurse managing a patient with aortic regurgitation begins with a comprehensive assessment, including a review of the patient's medical history, family history, and lifestyle factors. During the cardiac examination, the nurse listens for heart sounds and checks for signs of valve abnormalities. The nurse also observes for symptoms such as dyspnea, orthopnea, and paroxysmal nocturnal dyspnea and assesses the patient's endurance and daily activity tolerance.Based on the findings, the nurse...
