[The heart-lung transplant. Initial clinical experience]

Area of Science:

• Cardiovascular Surgery
• Pulmonology
• Transplant Surgery

Context:

• Heart-lung transplantation is a complex procedure for end-stage cardiopulmonary diseases.
• Brazil's initial clinical experience with this procedure was evaluated.
• The study period spanned from December 1988 to March 1990.

Purpose:

• To assess the initial clinical outcomes of heart-lung transplantation in Brazil.
• To document the surgical techniques and patient selection criteria used.
• To identify early complications and survival rates.

Summary:

• Four patients underwent heart-lung transplantation for conditions including cardiomyopathy, primary pulmonary hypertension, and pulmonary silicosis.
• Surgical technique involved harvesting heart-lung blocks using cardiopulmonary bypass and deep hypothermia, followed by specific anastomoses.
• Postoperative outcomes varied, with one early mortality, two short-term survivors, and one long-term asymptomatic patient. Complications included bleeding, acute pulmonary rejection, and obliterans bronchiolitis.

Impact:

• This initial experience highlights the challenges and potential of heart-lung transplantation in Brazil.
• Findings underscore the need for refined surgical techniques and improved clinical management.
• The study contributes to the growing body of knowledge on heart-lung transplantation outcomes in developing healthcare systems.
