Description : Check out this medical PowerPoint presentation titled "Echocardiographic Evaluation Of Prosthetic Cardiac Valves" by Dr Gaurav Kumar Chaudhary MD,DM( Cardiology).

This medical PowerPoint presentation talks about echocardiography as an important tool for evaluating the function and structure of prosthetic cardiac valves. It allows for non-invasive assessment of valve function and can help detect any potential problems before they become more serious.

Echocardiography is a non-invasive imaging technique used to evaluate the function of prosthetic cardiac valves. Prosthetic cardiac valves are used to replace damaged or diseased heart valves, and they can be mechanical or bioprosthetic. Echocardiography is an important tool to evaluate the function of prosthetic cardiac valves and detect any potential problems.

There are two types of echocardiography that can be used to evaluate prosthetic cardiac valves: transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE). TTE is a non-invasive procedure that uses ultrasound waves to create images of the heart from outside the body. TEE is a more invasive procedure that involves inserting a probe through the mouth and into the esophagus to obtain images of the heart from a closer perspective.

An echocardiographic examination performed 6 weeks to 3 months after valve implantation It allows for an assessment of the effects and results of surgery Serves as a baseline for comparison should complications or deterioration occur later Timing of assessment of prosthetic valve Cardiology Department K.G.M.U 2014 AHA/ACC Guideline for the Management of Patients With Valvular Heart Disease A Report of the American College of Cardiology/American Heart Association Task Force on Practice Guidelines

Asymptomatic uncomplicated patient is usually seen at 1–year intervals for a cardiac history and physical examination No further echocardiographic testing is required after the initial postoperative evaluation in patients with mechanical valves Who are stable Who have no symptoms No clinical evidence of prosthetic valve or ventricular dysfunction or dysfunction of other heart valves.

Fibrous pannus, is usually annular in location Pannus formation is more frequent on aortic than on mitral prostheses On mitral prosthetic valves, they most often occur on the atrial side of the prosthesis Typically presenting as a very dense immobile echo, pannus are typically seen in patients with Normal anticoagulation profile Subacute or chronic symptoms Pannus versus Thrombus Cardiology Department K.G.M.U

DVI (Doppler velocity index) DVI is a dimensionless ratio of the proximal velocity in the LVO tract to that of flow velocity through the prosthesis: DVI = VLVO/VPrAV Normal prosthetic valve function Mean DVI, 0.39; range - 0.28-0.55 A DVI < 0.25 is highly suggestive of significant valve obstruction Cardiology Department K.G.M.U DVI (Doppler velocity index )

Patient-prosthesis mismatch (PPM) It is Nonstructural dysfunction, a composite category that includes any abnormality that results in stenosis or regurgitation of the operated valve that is not intrinsic to the valve itself, exclusive of thrombosis and infection This includes inappropriate sizing, which is called valve prosthesis–patient mismatch (VP-PM) When the effective prosthetic valve area, after insertion into the patient less than that of a normal valve Patients with aortic PHV have obstruction to left ventricular outflow (similar to aortic stenosis), and patients with mitral PHV have obstruction to left atrial emptying (similar to mitral stenosis) Cardiology Department K.G.M.U
