  1. 1. Technique in Cardiovascular System BY Dr. Naveen Sharma Cosultant cardiology Ssb hospital , faridabad
  2. 2. Introduction
  3. 3. Atherosclerosis The thickening and hardening of arterial walls as a consequence of atheroma • Atherosclerotic lesions in coronary arteries can obstruct blood flow. • leading to an imbalance in myocardial oxygen supply and demand that presents as stable angina or an acute coronary syndrome (myocardial infarction [MI] or unstable angina).
  4. 4. ROLE OF STATINS
  5. 5. Angina pectoris angina pectoris is a characteristic: • Sudden, severe, crushing chest pain that may radiate to the neck, jaw, back, and arms. • Patients may also present with dyspnea or • Atypical symptoms such as indigestion, nausea, vomiting, or diaphoresis.
  6. 6. Biomarkers in cardiovascular disease • In a patient presenting to the emergency department with acute severe chest pain (suspected acute coronary syndrome), • a biomarker may help to differentiate patients with an acute myocardial infarction (MI) from those with unstable angina (eg, troponin I or T), acute pulmonary embolism (eg, D-dimer or ventilation perfusion scan), • .the extent of myocardial damage (eg, troponin); the severity of underlying coronary disease (eg, coronary angiography); and progression to heart failure (eg, B- type natriuretic peptide [BNP]).
  7. 7. NT-ProBNP
  8. 8. Ecg
  9. 9. Artificial intelligence (AI) may be an aid to interpreting ECG results, helping healthcare staff to diagnose diseases that affect the heart.
  10. 10. Echocardiography
  11. 11. STRAIN
  12. 12. Role of NO cardiovascular sysytem • In the cardiovascular system, NO is an important determinant of basal vascular tone, prevents platelet activation, limits leukocyte adhesion to the endothelium, and regulates myocardial contractility
  13. 13. SPECT imaging of perfusion and function • After injection of radiotracer isotope is extracted from blood by viable myocyte • Photons are emiited from the myocardium in proprtion of its magnitute of tracer uptake , in turn related to perfusion • Gamma camera captures the gamma rays and converts into informational data
  14. 14. Cardiovascular MRI and contrast agent • Gadolinium –based contrast agent • Appx after 15 min of injection transient plateu of GBCA is reached .myocardial perfusionCMR and most type of MRA Are perfomed during ist phase , late gadolinium enhancement are obtained during equilibrium phase .
  15. 15. • . Iron oxide nanoparticles (IONs) are a new class of contrast agents with unique properties that provide special opportunities in cardiovascular molecular imaging. • IONs are captured by macrophages and can be successfully used in the detection and evaluation of atherosclerotic plaques, abdominal aortic aneurysms, and inflammations related to myocardial infarction..
  16. 16. Coronary angiography • A procedure where an X-ray of the coronary arteries is taken after injection of a dye to look for blockages.
  17. 17. Ptca • is a minimally invasive procedure to open up blocked coronary arteries, allowing blood to circulate unobstructed to the heart muscle 1). Angioplasty involves temporarily inserting and inflating a tiny balloon where your artery is clogged to help widen the artery. PTCA has become the method of choice to treat patients with heart attack
  18. 18. OCT • Optical coherence tomography (OCT) is a invasive imaging technique that produces high resolution intracoronary images. Its general principle of operation is similar to IVUS, however OCT uses infrared light, not ultrasound.
  19. 19. Type of prosthetic valve
  20. 20. TAVI • minimally invasive procedure a new valve is inserted without removing the old, damaged valve
  21. 21. Asd device closure
  22. 22. PACEMAKER
  23. 23. IABP
  24. 24. EECP
  25. 25. ECMO • In extracorporeal membrane oxygenation (ECMO), blood is pumped outside body to a heart-lung machine that removes carbon dioxide and sends oxygen-filled blood back to tissues in the body. Blood flows from the right side of the heart to the membrane oxygenator in the heart-lung machine, and then is rewarmed and sent back to the body.
  26. 26. LVAD • left ventricular assist device (LVAD) is a pump that we use for patients who have reached end-stage heart failure. • Bridge-to-transplant therapy: This is a life-saving therapy for patients awaiting a heart transplant. Patients use the LVAD until a heart becomes available.
  27. 27. Artificial heart
  28. 28. • Biotechnology applications, especially in the field of medicine, have influenced healthcare sector immensely. • It has changed the face of the medical field. Genetic engineering contributed to safer and more effective treatments and medications. •THANK YOU
