The German Heart Centre, Munich (DHM) at the Technical University of Munich is one of the most modern specialised centres in Germany for the treatment of cardiovascular disease in adults and children. The free State of Bavaria is the responsible body for this hospital. Three highly specialised clinics (the Clinic for Cardiovascular Surgery, the Clinic for Cardiovascular Disease and the Clinic for Paediatric Cardiology and Congenital Cardiac Defects) as well as three institutes (the Institute of Anaesthesiology, Radiology and Nuclear Medicine and the Insti-tute of Laboratory Medicine) are all located at a single facility.

Surgical treatment of acquired cardiac defects

German Heart Centre Munich 1.8 % with heart-lung machine 0 % without heart-lung machine

Coronary bypass surgery

Dr. Norbert Mayr

Arteriosclerotic cardiovascular di-sease continues to be the most com-mon cause of death in Germany and other industrial nations. At the German Heart Centre Munich, coronary bypass surgery makes up about 40% of all surgical procedures.

Complete arterial revascularisation with in-situ use of both thoracic ar-teries (LIMA, RIMA) as well as of the radial artery is the procedure of choice in state of the art bypass surgery. The long-term patency rates of the arte-rial grafts are far superior to those of the great saphenous vein. The radial grafts and saphenous vein transplants are removed in a minimally invasive or endoscopic procedure.

Off-pump surgery:

Bypass surgery on the beating heart

Beating heart surgery (off-pump)

Beating heart surgery represents a further development in the surgical treatment of coronary arteries.

A heart-lung machine is not required for this procedure. A stabilising device is used in the area of anastomosis to restrict movement of the heart, and the heart can be positioned by means of a suction cup.

Heart transplants

Since the mid eighties, the orthotopic heart transplant has been accepted as the procedure of choice in the treatment of refractory terminal heart failure.

This procedure was successfully performed for the first time in Germany at the German Heart Centre Munich on May 7th, 1981. Today, heart transplantation is performed regularly at our clinic. The international one year survival rate is higher than 80% while the five year survival rate is higher than 60%.

Aortic valve surgery

Priv.-Doz. Dr. Walter Eichinger

Prof. Rüdiger Lange: “Aortic valve surgery is the most com-mon procedure performed in the area of aortic surgery. The aortic valve is usually too tight or is leaking and needs to be replaced by a biological or mechanical artificial valve. Aortic valve defects may be congenital or brought about, for examp-le, by a protracted infection where bacteria stick to the valve and destroy it. However, the cardiac surgeon also operates on dilatations (aneurysms) and tears (dissections) of the main thoracic arteries.”

16

Heart valve reconstruction („repair“)

Thanks to the development of new techniques, diseased valves can be “repaired” more and more, rather than being replaced (heart valve repair).

The procedure of heart valve repair requires highly experienced, specially trained surgeons and is therefore only performed in large cardiac surgical centres, such as the German Heart Centre Munich.

Surgical treatment of acquired cardiac defects

The German Heart Centre Munich is also one of the leading centres in Germany in the field of thoracic aor-tic surgery.

If the aortic valve ring is significantly dilated, combined with the presence of a pathological aortic valve, a valved conduit (tube prosthesis with inte-grated heart valve prosthesis) is fre-quently implanted. The coronary ostia

Thoracic aortic surgery

are anastomosed end-to-side with the prosthesis, thereby being re-imp-lanted (Bentall’s procedure).Today, a valve-sparing procedure is the method of choice where possible, especially if the aortic valve exhibits no macroscopic structural changes. However, this surgical technique ismore demanding from a technical point of view and requires a high level of surgical experience.

Valve-sparing surgery saves the pa-tient from the need of anticoagulants or later valve prosthesis replacement. Apart from that, the haemodynamics of the patient’s own valve are always more favourable than those of a valve prosthesis.

Keyhole surgery is being applied more and more in the field of cardiac surgery in specialised centres, such as the German Heart Centre Munich.

A technique that is not only advantageous for the patient from a cosmetic point of view, but is also a contributing factor to the success of surgery. Only few cen-tres in Germany have offered this innovative type of cardiac surgery to date.

The Clinic for Cardiovascular Surgery of the German Heart Centre Munich is specialised in the technique of minimally invasive heart valve surgery, parti-cularly in mitral valve repair with minimal incisions of five to six centimetresin length extending from the right rib cage.

22

Aortic valve replacement is also performed using keyhole surgery where possible. Only the upper half of the sternum is split for this procedure.

The incision is now a vertical incision in the middle of the chest measuring only about 6-8 centimetres instead of

Minimally invasive surgical procedures

20-30 centimetres in the traditional approach. When performed by experi-enced cardiac surgeons, the outcome is comparable with surgery involving a full sternotomy and complete opening of the rib cage. The advantages of key-hole surgery in aortic valve operations are considerable, particularly with regard to the healing process. Priv.-Doz. Dr. Joachim Weipert

Page 27: Clinic for Cardiovascular Surgery - DHM - Startseite · 2007-09-25 · Minimally invasive mitral valve surgery ... attending the Clinic for Cardiovascular Surgery during the past

23

The sternum is much quicker to heal following only a partial sternotomy. Since only the top half of the sternum is now severed, the lower part stabi-lises the upper part in the postopera-tive healing phase. In this way wound healing disturbances can be avoided almost completely. Furthermore, post-operative pain, for example during

breathing is significantly reduced.A partial sternotomy rather than a full sternotomy is now also performed for surgery on the ascending aorta.

Since the introduction of these new techniques in 2000, nearly every fifth operation in the German Heart Centre is now performed using keyhole surgery.

Minimally invasive surgical procedures

The radial artery and the saphe-nous vein are commonly used as bypass vessels. It is possible to use keyhole surgery for these pro-cedures.

Endoscopic harvesting of the radial artery and the saphenous vein in bypass surgery

A skin incision of approx. three cen-timetres (instead of the usual 25-30 centimetres) is required. Harvesting is performed by means of an endo-scope.

This method offers considerably better cosmetic results with a smaller wound area than the conventional method, while ensuring graft quality for its use in bypass surgery.

25

Surgeons at the German Heart Cen-tre Munich have developed a further innovative minimally invasive tech-nique for the repair of atrial septal defects.

The surgical occlusion has already been performed in children via an incision through the ribs on the right chest in order to spare patients a large vertical scar on the sternum. However, this technique has been advanced considerably.

Minimally invasive paediatric cardiac surgery

Prof. Lange: “It was not uncommon for such girls to later have differently sized breasts. This came about becau-se in prepubescent children it is im-possible to predict where exactly the breast will later develop. A larger sur-gical incision in this area may interfere with the development of breast tissue in puberty. We now avoid this problem by opening the rib cage from the side, practically just below the armpit. The breast tissue remains undamaged in this way and the breast can develop

normally. A scientific study performed in our clinic has proven this without doubt. The cosmetic result is sensa-tional.” This midaxillary muscle-sparing, right-sided thoracotomy has been available at the German Heart Centre Munich for over one year now for all prepubescent patients suffering from atrial septal defects.

Minimally invasive surgical procedures

Endoscopic surgery with the telemanipulator

Furthermore, the German Heart Centre Munich has a telemanipulator (robot) at its disposal for special surgical procedures. The German Heart Centre Mu-nich was one of the first hospitals worldwide to use a telemanipulator system for endoscopic cardiac surgery.

The first totally endoscopic mitral valve repair, i.e. without opening the rib cage, to be performed worldwide was carried out in 2000 at the German Heart Centre Munich. Furthermore, a number of purely endoscopic bypass operations have been performed successfully by means of the telemanipulator.

In addition, the clinic is currently conducting clinical trials and experimental studies to establish new surgical techniques using a telemanipulator. The goal of such techniques is to perform valve-sparing surgery and valve replacement on a closed thorax via four to five small ports. To date, we have already operated on a large group of patients with the aid of a robot. Partial steps of newly plan-ned techniques have been applied and optimised during this time.

Non-invasive treatment of aortic aneurysms

Interventional treatment of aortic

(aortic stent). It is placed by means

of a catheter via the femoral artery.

Various surgical procedures are ap-plied in the Clinic for Cardiovascular Surgery for the treatment of disorders related to the large intrathoracic artery (aorta). Among other procedures, so-called stents (inner vessel supports) have been implanted for several years now. The rib cage does not need to be opened for their positioning nor does the patient need to be attached to a heart-lung machine.

The Clinic for Cardiovascular Surgery specialises in particu-lar in the treatment of congenital cardiac defects.

Performing 550 surgical procedures annually in children, ado- lescents and adults with congenital heart defects, the clinic ranks among the leading international institutions in this field.

As a rule, complex congenital cardiac defects are repaired in the German Heart Centre Munich even in subjects weighing less than 2,000 grams.

The German Heart Centre Munich has a valve bank at its dis- posal in which human valves are freshly processed for implan- tation in children undergoing the commonly required pulmo-nary artery valve replacement in paediatric cardiac surgery.

Ebstein’s disease

Deputy director

Prof. Dr. Klaus Holper

Ebstein’s disease is a congenital heart defect in which the origin of the septal and/or posterior leaflet of the tricuspid valve is displaced in the right ventricle. Triscuspid valve insufficiency is the primary haemodyna-mic complaint.

The surgical technique developed at the German Heart Centre Munich (Monocusp patch with anterolateral displacement of the anterior leaflet) has made valve-sparing repair possible in 90% of patients suffering from Ebstein’s disease. The perioperative risk associated with this method is only slight, especially when compared on an international level. This reflects the safeness of the surgical technique. The majority of patients were in NYHA stage III prior to surgery. Long-term studies over a period of 30 years have revealed a significant improvement in nearly all patients in terms of their capacity for exertion (88 out of 90 patients in NYHA stage I or II). Further analysis has shown that early surgery is an essential factor in further reducing the morbidity and mortality rate as well as achieving a lasting improvement in the quality of life of such patients.

Minimally invasive pulmonary valve placement

Dr. Christian Schreiber

The Shelhigh Injectable Pulmonic Valve represents a new possibility for patients after repeated surgery of the right ventricular outflow tract (RVOT).

The porcine valve, mounted in a self-expanding metal frame, was first implanted at the German Heart Centre Munich in April 2005. A young patient with the most severe form of pulmonary valve insufficiency, who had undergone Fallot’s repair in the past, underwent implantation of a stented valve with median sternotomy via the dilated RVOT.

Quality assurance

Quality has always been of the utmost importance for the German Heart Centre Munich. As early as in the mid eigh-ties, the director at the time, Prof. F. Sebening, took up the

concept of quality assurance at a time when only few dealt with this subject.

Together with seven other hospitals, the Clinic for Cardiac Surgery took part in a

model project that was sponsored by the Ministry of Health. The aim of the project was to establish a quality assurance system for the entire area of cardiac surgery. One of the most comprehensive and successful schemes of external quality assurance in Germany emerged from this project.

All 87 hospitals and departments specialised in cardiac surgery participate in the scheme today and forward their records, featuring after all more than 300 characteristics, in anonymous format to a centralised location. This centre in turn analyses and compares all hospital data, after which each hospital is forwarded its own data in relation to the mean values of all other hospitals. A so-called hospital pro-file is thus produced, which shows us how we compare on a national level to other hospitals.

Every point represents a clinic for cardiac

surgery. The higher the number of sur-

gical procedures performed, the bigger

the points. The red point symbolises the

German Heart Centre Munich (data from

the German Heart Centre Munich only

for 2004, all remaining data from 1999 –

2004).

The green lines show the European mean

while the red line represents the versa-

tility of the centre.

The hospitals in the upper right field to

which the German Heart Centre belongs

perform more complex procedures com-

bined with better survival rates than the

European average.

Approx. 47,000 cardiovascular operations have been performed at the Clinic for Cardiovascular Surgery since its establishment 30 years ago. New techniques and scientific progress have made it possible to keep lowering the age at which congenital cardiac defects can be operated upon. Just as the age at which elderly patients can be successfully operated upon is constantly on the rise.

We pay particular attention to the development of quality assu-rance in the field of paediatric cardiac surgery. We participate in the European paediatric cardiac data bank in Warsaw. As the leading hospital for paediatric cardiac surgery we also take part on a national level, together with our Clinic for Paediatric Cardiology and Congenital Cardiac Defects, in the setting up of the German “quality assurance for paediatric cardiology” within the scope of the Federal Office for Quality Assurance.

During our C&D conferences, illnesses are discussed that have not taken the expected course. Following a short description of the case, physicians discuss whether something could have been done to affect the clinical course more favourably.
