Intravascular Ultrasound (IVUS) for Coronary Intervention
Coronary Intravascular Ultrasound (IVUS) equipment consists of an IVUS catheter, pullback device and the imaging console. If lesion lengths have to be assessed, motorized pullback is required. For assessing lesion morphology a manual pullback can also be done. While manual pullback allows concentration on specific lesions, it may miss some lesions in between if the pullback is not steady. Catheter has to be disengaged while evaluating coronary ostial lesions.
Heparin and intracoronary nitroglycerine are given before the guide wire is inserted after the coronary cannulation with a guide catheter. The IVUS catheter is then i...

Ballooning an obstructed prosthetic Aortic valve : Can be a real tense procedure!
A 76-year-old woman with a history of double valve replacement (Aortic and mitral valves) for rheumatic heart disease, presented with acute dyspnea after a switch from Warfarin to LMWH before a planned bone marrow biopsy.
The investigations revealed a stuck aortic prosthetic valve ,that showed a prohibitive gradient of more than 50 mmhg. Since, she refused further surgery, a rare and risky effort was made to balloon dilate the prosthetic valve leaflet, though it is not a standard approved modality. It was decided to dilate the supero-lateral orifice and the central orifices by simultaneous kissing balloon. The results w...

Differentiating Between Cardiac and Non-Cardiac Chest Pain
It is not always possible to be certain about the origin of chest pain just by its characteristics as the variation between individuals is quite a bit. A medical opinion should be sought in case of any significant chest pain so that important ailment is not missed. There can be a lot of overlap between symptoms due to heart disease and disease of other nearby organs.
Still some general observations are possible regarding chest pain originating from the heart. The typical pain of cardiac origin is a central chest pain which occurs on walking or other forms of exercise, known as effort angina. This pain is caused by insuffic...

Wednesday Bible Study: Ye Gods!
Now we get some (mercifully short) songs of praise. The fun thing about these is that they cast Yahweh as the greatest among a pantheon of gods. That ' s how people thought about gods in the time most of the Tanakh was written. You ' ve got your god, we ' ve got ours, but ours is the baddest baddass of all the gods. This is somewhat different from polytheistic religions. All the Roman or Norse gods were gods of the Romans or Norsemen, although Jupiter and Odin were the head honchos. So the basic structure of the Deuteronomistic history is that when the Israelites please God, he gives them victory over their neighbors,...

Echocardiographic evaluation in aortic regurgitation
Echocardiographic evaluation of aortic regurgitation, demonstrated through multiple images. Echocardiogram in parasternal long axis view shows dilated left ventricle, left atrium, aorta and a small portion of the right ventricle, which is usually the outflow region. Mitral valve leaflets seen in open position between the left ventricle and left atrium are thickened.
The large aortic regurgitation jet can be seen as a mosaic jet in the left ventricular outflow tract anterior to the anterior mitral leaflet. A portion of the thickened aortic valve can be seen between the aorta and left ventricle.
The AR jet is almost filling ...

Know About Cardiogenic Shock
When the heart is not able to pump enough blood for the needs of the body and the blood pressure falls, it is known as cardiogenic shock. Most important cause of cardiogenic shock is a heart attack. It is more likely to occur in those who are older, having blocks in multiple blood vessels of the heart, and in those with a previous heart attack. Cardiogenic shock is a potentially life threatening condition and needs urgent treatment. Even with treatment about half of those with cardiogenic shock might die.
Those with cardiogenic shock may have severe shortness of breath, weak pulse, rapid heart-beats, low blood pressure, un...

Cholesterol-Consuming Gut Microbes Lower Heart Disease Risk
Variations in the relative proportions of microbial species making up the gut microbiome apparently contribute to variations in LDL-cholesterol in the bloodstream. Lower LDL-cholesterol sustained over a lifetime produces a slower development of atherosclerotic plaque, and lower risk of consequent cardiovascular disease. While it seems likely there is no one optimal gut microbiome, there are certainly specific improvements that can be achieved for most older individuals. Fortunately, producing lasting changes in the balance of microbial populations making up the gut microbiome is an achievable goal. Fecal microbiota transpl...

What is the reason for sudden breathlessness at night in those with heart disease?
Sudden breathlessness at night in those with known heart disease is usually due to collection of fluid in the lungs (pulmonary edema). During day time, when one is walking about, any extra fluid in the body tends to collect in the legs, due to the effect of gravity.
Extra fluid in the body can occur due to failure of heart, kidneys, liver and rarely due to other causes. In heart failure, the extra fluid is due to inability of the heart to pump out blood well. This can occur if the heart muscle is weak or there is obstruction to a valve regulating the flow of blood inside the heart.
At night, when one is lying down, extra f...

Complexity and chronic pain*
*Persistent didn’t alliterate so well!
I’ve been pondering what makes persistent pain so complicated? What is it about this problem that means clinicians use terms like ‘heart-sink’, or ‘problematic’, or ‘difficult’ when they talk about people living with pain?
While nociception and all the associated neurobiological processes associated with pain are undoubtedly complex (and poorly understood), I don’t think this is what people mean when they describe chronic pain is complex. After all, there are loads of body systems and disease processes that are complex.
I...

Ashman Phenomenon in A F and Fish Criteria
Transcript of the video: Now I am going to describe Ashman Phenomenon in atrial fibrillation, which is responsible for a long and short sequence followed by a wide QRS, in atrial fibrillation noted on ECG, which may resemble a ventricular ectopic beat.
This is the diagrammatic representation of Ashman phenomenon. You have sequences of AF beats, and a long cycle occurs, followed by a short cycle. So this QRS is aberrant, having rSR’ pattern, resembling right bundle branch block pattern. This was described by Richard Ashman, from Lousiana State University School of Medicine in New Orleans. This is the long cycle. Durin...

Sunday Sermonette: The usual BS
We now have three fairly short pieces, all of which are in the same vein. The righteous will prosper, the wicked will have their downfall. Sad to say, it just ain ' t so, and repeating it every Saturday won ' t make it true. If we want the righteous to flourish, and the wicked to have their downfall, we need to make it happen ourselves. God is of no help.A Psalm. A Song for the Sabbath.92 It is good to give thanks to theLord, to sing praises to thy name, O Most High;2 to declare thy steadfast love in the morning, and thy faithfulness by night,3 to the music of th...
