In this video, Dr. Sameer Shrivastava, Heads the department of Non-Invasive Cardiology at Fortis Escorts Heart Institute, New Delhi, will talk about how to diagnose dissection of aorta? Dissection of aorta is a very confusing disorder unless a key suspicion is present.

In such patients, history is important. Dr. Sameer will also explain the symptoms which are help to diagnose the disorder. He will tell us many a times ECG are normal. In such patients, hypertension exist and the pulses are uneven, for example, absence of pulse in one limb or carotids, etc. Whenever you have a strong suspicion of dissecting aorta, then the first test to be done is 2d-echo and Transesophageal echocardiography (TTE). TTE is done as when 2d-echo is unable to detect dissecting aorta due to certain limitation.

In this video, Dr. Sameer Shrivastava, Heads the department of Non-Invasive Cardiology at Fortis Escorts Heart Institute, New Delhi, will talk on diagnosis of coarctation of aorta. Coarctation of aorta is the most misdiagnosed disorder when a person comes in adulthood. The reason behind this is that physician’s do not look at the femoral arteries or the peripheral lower limb arteries.

Dr. Sameer discusses that if a person is suffering from hypertension at a young age, then signs and symptoms of the coarctation of aorta should be investigated. He will also talk on differential blood pressure between the upper and lower limbs which can help to diagnose coarctation of aorta. For the detection of it, echocardiography is advised. Hence, this is one of the few conditions of blood pressure which need to be detected aggressively.

Dr. Sameer Shrivastava, Heads the department of Non-Invasive Cardiology at Fortis Escorts Heart Institute, New Delhi, in this video will talk on diastolic dysfunction. He will explain that in diastolic dysfunction, due to failing of heart which cannot contract or push out blood adequately when it is contracting. The heart expands with stiffness or reservations in this abnormality. The stiffness of heart causes the problem of filling of blood. 

Dr. Sameer tells and explains the parameters of diastolic dysfunction. He will talk that when a person complains of shortness of breath, then how to rule out lungs problems or coronary artery disease. Diastolic dysfunction can be only be detected through echocardiography. Also, invasive techniques are available to calculate diastolic dysfunction.

In this video, Dr. Sameer Shrivastava, Heads the department of Non-Invasive Cardiology at Fortis Escorts Heart Institute, New Delhi, will differentiate between diastolic dysfunction and diastolic failure. Diastolic dysfunction is detected objectively on echocardiography which may or may not manifest into symptoms. It may have restricted filling of blood.

In this video, Dr. Sameer Shrivastava, Heads the department of Non-Invasive Cardiology at Fortis Escorts Heart Institute, New Delhi, will discuss the guidelines for mitral stenosis. Earlier the severity of mitral stenosis was considered as less than 1 cm square but with recent guidelines, lesser than 1.5 cm square is considered as severe mitral stenosis.

Regardless of the severity of mitral stenosis, the first and foremost intervening is the symptoms. If the person is symptomatic then even it is moderate valvular disease, then it needs to be corrected. Dr. Sameer will also talk on how mitral stenosis is mostly related to young rheumatic children. He will discuss the treatment modes in such children and long it can be managed with out surgery. He will also talk the problems when patients with mitral stenosis are asymptomatic.

In this video, Talks about indications for not intervening pure mitral stenosis by Dr. Sameer Shrivastava, Heads the department of Non-Invasive Cardiology at Fortis Escorts Heart Institute, New Delhi. If it is mild mitral stenosis, then it is a class three indication. It shouldn’t be interfered or might turn complicated. These patients are well managed with bacterial endocarditis prophylaxis and some diuretics. 

In this video, Dr. Sameer Shrivastava, Heads the department of Non-Invasive Cardiology at Fortis Escorts Heart Institute, New Delhi, will talk about the indications for surgery in mitral regurgitation. If patients are symptomatic, then it indicates surgical intervention. If the patient has a significant mitral regurgitation with symptoms then he requires surgery. 

Dr. Sameer tells us that the correct guidelines to intervene in mitral regurgitation are not yet present. The existing guidelines indicate that the patient is subjected to surgery only. When the mitral regurgitation is of rheumatic origin, then mitral valve replacement is needed versus prolapse where the surgery should be repair of the valve. He will explain the repair as well as replacement of valve methods.

In this video, Dr. Sameer Shrivastava, Heads the department of Non-Invasive Cardiology at Fortis Escorts Heart Institute, New Delhi, will talk on the case of aortic stenosis. In case of severe aortic stenosis and the patient is asymptomatic, then they do not need surgery. Severe aortic stenosis with symptomatic patients are the candidates for surgery or valve replacement. 

Dr. Sameer will also discuss that even in moderate aortic stenosis and symptomatic patients, surgery or valve replacement is suggested. He will also explain a new method known as TAVI (Transcatheter aortic valve implantation), recently introduced for the intervention of aortic stenosis. It is a procedure like angioplasty or angiography. He will tell the advantages and disadvantages of the procedure TAVI.

In this video, Dr. Sameer Shrivastava, Heads the department of Non-Invasive Cardiology at Fortis Escorts Heart Institute, New Delhi, will discuss the guidelines for intervention in a case with aortic regurgitation. Aortic regurgitation is a lesion of valves which is tolerated for a very long time. Many people are asymptomatic. Dr. Sameer will highlight the guidelines when there is a need for surgery. 

If the patient has a pulmonary arterial hypertension or if the heat functioning of the left ventricular ejection fraction is reducing then he is a candidate for surgery. If arrhythmias in the form of atrial fibrillation is seen and even if patient is asymptomatic, then he needs to be operated. He will also explain why only valve replacement is recommended in aortic regurgitation.

In this video, Dr. Sameer Shrivastava, Heads the department of Non-Invasive Cardiology at Fortis Escorts Heart Institute, New Delhi, will talk on significance of interatrial septal aneurysm. In interatrial septal aneurysm, the echocardiography will show a septal bulge either towards the right atrium or left atrium or it might be seen in both the sides. The interatrial septal aneurysm is significant only in young stroke. In these patients of interatrial septal aneurysm, put them on anti-platelet therapy and keep them in observation.
