About Prof. Dr Horst Sievert - Cardiology Frankfurt

Prof. Dr Horst Sievert is a specialist in interventional cardiology and angiology. Since 2003, he has headed the CardioVascular Centre Frankfurt (CVC) at the St Katherine Hospital in Frankfurt. The centre’s focus is placed on the diagnosis and therapy of cardiovascular diseases using latest minimally invasive treatment methods with the aid of heart catheters.

At the CVC, highly qualified medical experts work hand in hand to provide the best possible care for patients. In addition to the specialist disciplines of cardiology, the team also includes experts in cardiac surgery, radiology, and internal medicine. This bundling of specialists for cardiovascular diseases under one roof is what distinguishes the CVC under the direction of Prof. Dr Sievert.

CVC Frankfurt – Centre for Minimally Invasive Cardiology and Angiology in Frankfurt

The CVC offers examination and treatment methods of cardiology and angiology at the highest level. In addition to non-invasive techniques such as ultrasound examination (echocardiography, Doppler sonography), these include in particular invasive techniques such as heart catheter (coronary angiography). The early detection of cardiovascular diseases as well as a targeted therapy can significantly reduce late sequelae such as heart attacks and strokes. Early treatment by an experienced heart specialist such as Prof. Dr Sievert is therefore crucial for the further prognosis of heart patients. His clinical and scientific work focus on interventional cardiology and angiology. He is one of the leading international specialists and treats patients from all over Germany and Europe as well as overseas.

Prof. Dr Sievert – Heart Catheter Specialist (Coronary Angiography) in Frankfurt

One diagnostic and therapeutic focus of Prof Sievert is the performance of heart catheter examinations. In coronary angiography, a vascular catheter is pushed to the heart, and a contrast medium under x-ray fluoroscopy is used to visualize constrictions or other heart diseases. The advantage of the procedure is that dangerous vascular constrictions can be treated directly.

Interventional Cardiology in the Case of Coronary Heart Disease: (CHD)

Coronary heart disease (CHD) is characterized by a gradual “calcification” and constriction of the vessels supplying the heart. These constrictions cause symptoms only in very late stages and can result in a heart attack (myocardial infarction) if the vessel is completely blocked. During coronary angiography, Prof. Sievert expands these constrictions of the vessels using a balloon and keeps them open with a stent.

TAVI and MitraClip Frankfurt – Heart Valve Surgery by Means of Heart Catheter

The most common diseases of heart valves of advanced age are aortic valve stenosis and mitral valve insufficiency. In the case of changes in the heart valves, symptoms (which are often very unspecific) occur only at a very advanced stage of the disease. They can manifest themselves, for example, in dizzy spells, shortness of breath, or rapid fatigue.

Thanks to modern catheter procedures, Prof. Sievert is able to treat constricted aortic valves or leaking mitral valves using heart catheters without major surgery. The first TAVI was performed at the CVC in 2005 and the first MitraClip implantation in 2009. In the CVC, one of the first tricuspid valves worldwide was also implanted using minimally invasive techniques. Comparably good long-term results are available, especially for older patients. TAVI (transcatheter aortic valve implantation) or the MitraClip (for mitral valve leakage) are thus good alternatives to classical open-heart valve surgery, especially for patients with concomitant diseases.

Treatment Options for Hypertension

Renal denervation (RDN) is a catheter treatment for hypertension. The catheter is pushed from the groin into the renal arteries via the abdominal artery. Here, the nerve fibers on the arterial wall are atrophied. This is supposed to reduce hypertension in the long term. The procedure takes about 45 minutes and is considered a safe treatment with few side effects. Another very effective method is baroreceptor stimulation.

PFO Occlusion – Minimise Risk of a Second Stroke

It is estimated that every fourth person has an open Foramen oval which is a small hole in the septum of the heart near the atria. Usually, the hole closes by itself after birth. But often, the opening remains disclosed. Although most patients remain unaware of the defect, a PFO can cause a stroke. Prof. Sievert can easily close the deformity using a cardiac catheter. The procedure is recommended for those patients who have suffered from a stroke already and where no other cause but a persistent Foramen oval has been found.

Interventional Left Atrial Appendage Occlusion (LAA) for Atrial Fibrillation

For patients with atrial fibrillation who cannot take blood thinners on a long-term basis, an interventional left atrial appendage occlusion (LAA) offers a good option for stroke prophylaxis. During this procedure, Prof. Sievert uses a cardiac catheter to insert an LAA occluder into the atrial appendage, because atrial fibrillation often creates blood clots at this location. The LAA occlusion thereby significantly reduces the risk of stroke for patients at risk of bleeding.

Well-Informed Heart Patients

Prof. Dr Sievert and his team regularly offer doctor-patient seminars in order to provide patients and their relatives with comprehensive yet understandable information on their diseases and the potential consequences.
