Heart catheterisation: procedure and significance in modern cardiology<\/h1>\n

A cardiac catheterisation allows for an accurate assessment of the coronary arteries and heart function. Using a thin catheter, which is advanced to the heart via a blood vessel, measurements can be taken and the vessels visualised with the aid of contrast medium. Cardiac catheterisation in Munich represents a central element for the Cardiological diagnostics<\/a> Dear.<\/p>\n

Depending on the medical question, a distinction is made between Right heart catheterisation<\/a> and Left ventricular catheter<\/a> distinguished. The following explains how a catheter examination proceeds, how long it takes, and what diagnostic information it provides.<\/p>\n<\/div><\/div>

Cardiac catheterisation overview<\/h2>\n<\/div><\/div><\/div><\/div>

A cardiac catheterisation is an established invasive procedure for assessing the coronary arteries, heart chambers and heart function. It not only enables accurate diagnosis but also direct therapy, for example, for narrowed coronary arteries.<\/p>\n

During a cardiac catheterisation, the catheter is advanced to the heart through a blood vessel. Access is usually gained via the radial artery in the wrist or the femoral artery in the groin. Using X-ray contrast medium, the coronary arteries and heart chambers can be visualised on a monitor. Patients remain awake and able to communicate during the procedure.<\/p>\n

A heart catheterisation typically lasts 30 to 60 minutes, though more complex procedures or additional therapeutic measures may take longer.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

Indications for cardiac catheterisation<\/h2>\n<\/div><\/div><\/div><\/div>

A heart catheterisation is advisable when an accurate assessment of the coronary arteries, heart chambers, or heart valves is required.<\/p>\n

Typical indications are:<\/p>\n

    \n
  • Suspicion of relevant coronary heart disease<\/li>\n
  • unstable angina pectoris or acute myocardial infarction<\/li>\n
  • coronary heart disease (CHD)<\/li>\n
  • Myocarditis (inflammation of the heart muscle)<\/li>\n
  • Heart valve malfunction<\/li>\n
  • Pulmonary hypertension<\/li>\n<\/ul>\n

    Furthermore, cardiac catheterisation can be used before planned heart procedures, such as valve or bypass surgery, and as a therapeutic procedure for coronary heart disease. As Cardiology am Promenadeplatz, we are your ideal medical point of contact for cardiac catheterisation in Munich.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

    Risk groups and contraindications for cardiac catheterisation<\/h2>\n<\/div><\/div><\/div><\/div>

    A cardiac catheterisation examination is usually also possible in older patients, provided their general health permits. Cardiac catheterisation should not be performed in the following (relative) contraindications:<\/p>\n

      \n
    • Contrast medium allergy<\/li>\n
    • Severe renal insufficiency<\/li>\n
    • coronary heart disease (CHD)<\/li>\n
    • Hyperthyroidism<\/li>\n<\/ul>\n

      Patient preparation for cardiac catheterisation<\/h2>\n

      Thorough preparation is important before a cardiac catheterisation. This includes a detailed information and consent discussion, an ECG check, and blood tests to evaluate blood coagulation, kidney, and thyroid values. All preliminary examinations take place here in our cardiology department at Promenadeplatz. The cardiac catheterisation itself will be performed in one of our partner clinics. We will arrange the appointment in advance.<\/p>\n

      On the day of the examination, patients should be fasting. Water can be drunk in small quantities up to two hours before the procedure. Medication should be taken as directed by your doctor.<\/p>\n

        \n
      • Immunosuppressants: take as usual<\/li>\n
      • Metformin: stop two days beforehand, in consultation with your doctor<\/li>\n
      • Anticoagulants such as Eliquis, Rivaroxaban, Pradaxa or Lixiana: pause<\/li>\n
      • Marcumar: INR on the day of the examination around 2.0\u20132.4<\/li>\n<\/ul>\n<\/div><\/div><\/div><\/div><\/div>
        <\/div><\/div>

        The procedure for a heart catheterisation<\/h2>\n

        The cardiac catheterisation procedure is performed via an arterial access point in the wrist or groin (radial or femoral artery). After disinfection and local anaesthesia, a sheath is inserted, through which the catheter is advanced to the heart under X-ray guidance.<\/p>\n

        Contrast medium is injected in minimal doses to make the coronary arteries, heart ventricles, and pulmonary arteries visible. A temporary feeling of warmth due to the contrast medium is normal.<\/p>\n

        The duration of a cardiac catheterisation procedure is usually between 20 and 60 minutes, depending on the scope of the examination or additional therapeutic measures. Sedation or painkillers can be used if necessary, as pain and pressure sensations vary individually.<\/p>\n

        Risks and potential complications of cardiac catheterisation<\/h2>\n<\/div><\/div><\/div><\/div>

        The cardiac catheterisation is an established routine procedure, yet as with any invasive intervention, risks and complications can occur.<\/p>\n

        Possible complications include:<\/p>\n

          \n
        • Allergic reaction to contrast agent<\/li>\n
        • Vascular injuries to arteries or veins<\/li>\n
        • Bruising at the injection site<\/li>\n
        • Unstable circulatory situation during the examination<\/li>\n
        • Emergency bypass surgery<\/li>\n
        • Rare: Stroke<\/li>\n
        • Very rare: heart or lung injuries, e.g.: lung haemorrhage<\/li>\n
        • <\/li>\n<\/ul>\n

          Potential risks are discussed in detail in advance during the consultation in our cardiology practice with patients.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

          <\/div><\/div>

          Aftercare of a cardiac catheterisation<\/h2>\n

          Following the completion of the examination, the cardiac catheter in Munich will be removed and the access site closed. Finally, the puncture site will be treated with a pressure bandage or compression system to prevent bleeding. The bandage should remain in place for several hours while patients rest. Depending on their condition, patients will remain under observation on the ward for some time.<\/p>\n

          Due to taking medication for the examination, driving a vehicle immediately after the procedure is not permitted. A safe journey home should therefore be organised in advance.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

          <\/div><\/div>

          Post-heart catheter<\/h3>\n<\/div><\/div><\/div><\/div>

          In the first few days after the examination, the puncture site should be rested to ensure optimal healing. This includes:<\/p>\n

            \n
          • Avoid heavy lifting and carrying<\/li>\n
          • Resume sporting activities or cycling only after consultation.<\/li>\n
          • Avoid movements that strain the arm or groin area.<\/li>\n
          • Avoid hot baths or swimming<\/li>\n<\/ul>\n

            This helps to prevent bleeding or post-operative bleeding and supports the healing process.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

            <\/div><\/div>

            Possible after-effects<\/h3>\n<\/div><\/div><\/div><\/div>

            Occasionally, a small bruise might form at the injection site. This is usually not a problem as long as the bruise is soft and doesn't grow significantly. Other possible<\/p>\n

            Side effects are:<\/p>\n

              \n
            • Drop in blood pressure<\/li>\n
            • Sweating<\/li>\n
            • Nausea or vomiting<\/li>\n<\/ul>\n

              You should contact our cardiology practice immediately if your symptoms are persistent or worsening, or if signs such as increasing swelling, thickening around the puncture site, or severe pain develop.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

              Results of cardiac catheterisation<\/h2>\n

              The results of the cardiac catheterisation are available during or on the same day as the procedure. After that, further care and treatment planning will take place in our cardiology practice. The results will be discussed directly, and if necessary, further examinations, such as a CT scan, can be performed. In cases of significant findings, cardiac surgery, such as a bypass operation, may also be required.<\/p>\n<\/div><\/div>
