About the department

The Department of Cardiac Surgery at the HELIOS Heart Surgery Clinic Karlsruhe offers the full range of modern cardiac surgery for adults with the exception of heart and lung transplantation. The department specializes in transcatheter aortic valve implantation (TAVI), heart valve reconstruction and replacement, treatment of heart rhythm disorders, aortic diseases and other minimally invasive treatment methods. The department is the certified Center for Aortic Valve Transcatheter Implantation. The department is headed by Prof. Dr. med. Uwe Mehlhorn. Prof. Mehlhorn is one of the leading cardiac surgeons in Germany, he has long clinical experience, is actively engaged in research activities, regularly speaks at international conferences, etc.

The department's infrastructure includes 96 beds for patients, 5 operating rooms, including the so-called hybrid operating room. It is used to perform the most sparing aortic valve surgery  –  transcatheter aortic valve implantation (TAVI). It is possible to avoid the chest opening during surgery. This technology is particularly suitable for the aged patients, who would have extremely high risks in conventional surgical aortic valve  replacement.

The department also offers the full range of modern heart valve surgery, ranging from traditional surgery to minimally invasive interventions. Whenever possible, the department's specialists strive to preserve the patient's own heart valve and reconstruct it. For example, the reconstruction is performed in valve insufficiency. As a rule, the stenotic valves cannot be maintained. In such cases, the valve replacement surgeries are performed.

In addition, the department's cardiac surgeons have long experience in the surgical treatment of aortic diseases. All modern methods are available for the treatment of aortic aneurysm. If the aneurysm is located in the upper aorta, doctors perform its replacement (replacement of the aorta section). If the aneurysm is at the level of the abdominal or thoracic aorta, the surgeons in most cases implant a prosthesis in the form of a tube (stent).

Other activities of the department include surgery for congenital heart defects, surgical treatment of cardiac arrhythmias, implantation of an artificial heart, bypass grafting, etc. The main task of the department's doctors is to offer each patient an individual, most sparing treatment.

The department’s therapeutic range covers the following options:

  • Minimally invasive surgical interventions
    • Transcatheter aortic valve implantation (TAVI) 
    • Minimally invasive aortic valve replacement (MIC-AKR/E)
    • Minimally invasive mitral and tricuspid valve surgery (MIC-MKR/E; MIC-TKR/E)
    • Minimally invasive direct coronary artery bypass grafting  (MIDCAB)
    • Hybrid myocardial revascularization (MIDCAB + PCI with stenting)
  • Myocardial revascularization
    • Total coronary artery bypass grafting using both internal thoracic arteries
    • Coronary artery bypass grafting on the functional heart, without using the off-pump coronary artery bypass grafting (OPCAB)
    • Comprehensive coronary artery bypass grafting in recurrent coronary heart disease after previous surgery
  • Heart valve surgery
    • Reconstructive surgery of the mitral/tricuspid valve, including in the form of combined surgical interventions with coronary artery bypass grafting and simultaneous operations on several valves
    • Reconstructive aortic valve surgery in combination with surgical treatment of aortic aneurysm (acute aortic dissection type A, Bentall procedure, David operation)
    • Replacement of all heart valves using biological/mechanical prostheses, including in acute/chronic endocarditis
  • Heart failure and heart rhythm disorders
    • Implantation of pacemakers, implantable cardioverter-defibrillators (ICD), event recorders (heart rate recorders)
    • Cardiac resynchronization therapy (CRT)
    • Comprehensive revision after implantation, including in sepsis, with laser removal of electrodes
    • Removal of blood clots from atrial and pulmonary veins, including with the use of minimally invasive methods
    • Implantation of mechanical assist devices (artificial heart ventricles – LVAD, RVAD, BiVAD) as a temporary measure before heart transplantation or as a permanent therapy
    • Round-the-clock (24 hours a day, 7 days a week) care (extracorporeal life support (ECLS) / extracorporeal membrane oxygenation (ECMO)) with mobile mini-devices of the artificial heart and lungs for the use out of the hospital in patients with cardiogenic shock
  • Thoracic aortic surgery
    • Aortic aneurysm surgery (for example, supracommissural replacement of the ascending aorta, Bentall procedure, David procedure), also in combination with reconstructive aortic valve surgery
    • Surgical treatment of acute aortic dissection type A (AADA)
    • Aortic arch surgery with the help of hybrid method
  • Surgical correction of heart defects in adults
    • Minimally invasive closure of a persistent oval window or atrial septal defect
    • Closure of postinfarction ventricular septal defect
  • Cardiac tumor surgery
    • Removal of cardiac tumors (for example, atrial myxoma), including the minimally invasive methods
  • Other treatment options
