CABG is the most common cardiovascular surgery done world wide .
When the ventricle is dilated it is a common practice to do a ventricular reduction surgery.
It was a logical to expect benefit when we correct the adverse remodelling of heart that aoccur following an MI.
The STICH trial compared plain CABG with ventricular reconstruction and reduction [...]

Can coronary collaterals provide more blood flow than a CABG ?

Coronary collateral circulation is the most poorly understood, and often neglected concept among the cardiology community.There is a general perception , in obstructive CAD , coronary collaterals are an inferior modality of back up blood supply than artificial collateral (Also called CABG ) ! One of the reasons, it is been ridiculed by many mainstream [...]

Coronary artery perforation is a dreaded complication of PCI. Perforations are the Interventional cardiologists ultimate worry as they need to manipulate their hardware for long periods in many complex lesions. Especially it is a real threat in chronic total occlusions.
Still , an important fact is , many of the coronary perforations are not life [...]
Can hand steal blood from the heart ?

CAD is the major cardiovascular disease of our population.
CABG is the most common cardiac surgery done world over.
LIMA to LAD graft is the most common by pass done.
The purpose is to short circuit some of the blood meant for the hand to the heart.
But , is it always a helping hand ?
May not be . [...]
And now , a biochemical diagnosis for pulmonary hypertension !

Biochemical diagnosis for PHT and Eisenmenger syndrome
Identifying reversibility of pulmonary arterial hypertension remains a difficult clinical problem.Heath edwards grading of pulmonary hypertension is based on lung pathology .Grade 4 and 5 constitute severe obstructive vascular pathology including pulmonary vascular necrosis.
Lung biopsy is an invasive procedure and has a huge risk in patients with elevated [...]
What are the advantages or disadvantages of having a short or long left main coronary artery ?
Posted in Uncategorized, tagged left main artery on March 26, 2009 | Leave a Comment »
Left main coronary artery disease is a major form of CAD .
A long left main by virtue of it’s surface area statistically , are more prone for atherosclerosis as it preferentially affect the proximal vessel.A long and tubular leftmain generally give the LCX branch at right angles(In the above pateint it is 90*).This makes [...]
Land mark papers in cardiology : Beta blockers in cardiac failure .The power of simple observation far exceeds the synthesised evidence

Beta blocker use in cardiac failure has come a full circle from a “contraindication to indication”
You don’t need gimmicks of statistics for science to progress. What you require is meticulous observation.
F .Waagstein of Sweden just did this with a study population of seven patients .
This land mark study , was least significant statistically , [...]
What is the difference between dopamine and dobutamine and what is the clinical significance ?

Dopamine and dobutamine are the most commonly used inotropic agents in clinical cardiology.
The following table represents a simple comparison of the two drugs.
The Aortic dissection : What you wanted to know about true and false lumen !

Why is identifying false and true lumen important ?
This helps the interventional cardiologist to plan the specific therapeutic procedure .
Is it really difficult to differentiate the two ?
One may wonder , why is that difficult to identify the true aortic lumen by echo, after all , the LV empties the blood into true aortic lumen [...]
What are the precautions to be taken during PCI when we encounter thrombus containing lesions ?

First and foremost is
Avoid the procedure if not really indicated.A lesion which has more thrombus load than a plaque and it is , subcritical and not limiting the flow , PCI may be inappropriate especially if the ACS is stabilised.
Adequate anticoagulation along with 2b 3a blockers should be used
Predilatation should be minimally used or to [...]
