Thrombolysis of a prosthetic mitral valve in a 50-day-old child

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology
• Interventional Cardiology

Background:

• Prosthetic valve implantation in infants presents unique surgical challenges.
• Thrombus formation on prosthetic valves can lead to severe complications, especially in pediatric patients.
• Early diagnosis and management of prosthetic valve thrombosis are critical for patient outcomes.

Purpose of the Study:

• To report a case of prosthetic mitral valve implantation in a neonate.
• To describe the successful management of early postoperative prosthetic valve thrombosis using thrombolysis.
• To highlight the feasibility and efficacy of thrombolytic therapy in pediatric cardiac surgery patients.

Main Methods:

• Case presentation of a 50-day-old infant undergoing prosthetic mitral valve implantation.
• Postoperative monitoring for complications, including echocardiography to assess valve function and thrombus formation.
• Administration of thrombolytic therapy to address obstructive thrombus in the early postoperative period.

Main Results:

• Successful implantation of a prosthetic mitral valve in a critically ill infant.
• Development of an obstructive thrombus on the prosthetic valve in the early postoperative phase.
• Complete resolution of the thrombus and restoration of normal valve function following thrombolytic treatment.

Conclusions:

• Prosthetic valve implantation is a viable option for complex congenital heart disease in neonates.
• Early thrombolysis can be a safe and effective treatment for obstructive prosthetic valve thrombosis in infants.
• This case underscores the importance of vigilant monitoring and timely intervention in pediatric cardiac surgery.
