Diagnosis of partial anomalous pulmonary venous connection in Hannover Medical School (MHH)

About the department

The Department of Adult and Pediatric Cardiothoracic Surgery, Vascular Surgery, Heart and Lung Transplantation at the Hannover Medical School offers the full range of services in these medical fields and ranks among the world's leading medical centers. It provides the effective surgical treatment of diseases of the heart, heart valves, congenital heart defects, pathologies of blood vessels and thoracic organs. The department specializes in the implantation of pacemakers, defibrillators, and mechanical circulatory support systems. In addition, the department is a renowned center for heart and lung transplantation, as well as combined heart-lung transplantation. The team of the department's surgeons annually performs about 2,000 operations using a heart-lung machine. The medical facility also performs more than 250 heart surgeries for children, about 120 lung transplantations and 30 heart transplantations every year. It is not surprising that performing so many complex operations, the department ranks among the best European Heart Surgery Centers. The department is headed by Prof. Dr. med. Arjang Ruhparwar.

The key to excellent treatment results, which the department has been showing over the years, is not only the high competence of doctors, state-of-the-art equipment and advanced surgical methods, but also active research activities. The medical facility ranks among the leading research centers in Europe, which carries out continuous work to improve the existing treatment methods in the field of cardiothoracic, vascular and transplant surgery, as well as develops and implements innovative therapeutic techniques.

Of particular interest in the field of cardiac surgery is the surgical treatment of heart valve diseases, coronary artery pathologies, as well as operations for the implantation of ventricular assist devices. Whenever possible, cardiac surgery is performed using minimally invasive surgical techniques, without thoracotomy. This innovative approach to treatment allows the patient to recover from surgery in the shortest possible time and avoid serious risks related to classical open surgery.

The department's pediatric cardiac surgeons deal with the treatment of congenital heart defects in children of all age groups. The department has more than 40 years of experience in this field, so surgeons have the necessary clinical skills to provide high-quality medical care to young patients with any cardiac diseases – from atrial septal defect to ventricular hypoplasia. The department also supervises adult patients with congenital heart defects.

The department's thoracic surgeons in collaboration with pulmonologists provide the surgical treatment of all benign and malignant diseases of the lungs, bronchi and trachea, thoracic wall and diaphragm. If lung cancer is diagnosed in a patient, the specialists from related medical disciplines are involved in the therapeutic process, who cooperatively develop the most effective and sparing treatment regimen. The specialists also have vast experience in surgery for thoracic wall deformities. The most common intervention in this area is the minimally invasive Nuss procedure to correct pectus excavatum. The operation has been performed in the department since 2014.

The department's doctors achieve excellent results in vascular surgery. Therapeutic options include both classic open surgery and modern endovascular interventions. The department regularly performs surgeries to treat carotid artery stenoses and occlusions, aortic reconstruction surgeries, bypass grafting, as well as decompression surgery for thoracic outlet syndrome. Vascular surgeons can be proud of their excellent results in the treatment of varicose veins and chronic venous insufficiency. The service range in the field of vascular surgery is complemented by percutaneous transluminal angioplasty, lysis therapy, implantation of port systems, and the formation of dialysis access.

An equally important area of the department's specialization is heart, lung, and heart-lung transplantation. The transplantation program in the department started back in 1983. Since then, the number of heart and lung transplantations, as well as simultaneous heart and lung transplantations has grown steadily. Today, the department is a leader in transplantation medicine in Europe. The survival rates of patients after lung transplantation reach 87% after 1 year and almost 50% after 10 years – the best results in the world. Both the pediatric lung transplantation program (more than 10 transplants per year) and the lung donation program introduced in 2012 are unique in Germany.
