Cardiology MCQ 319: de Vega’s annuloplasty
de Vega’s annuloplasty is commonly used for: a) Mitral valve b) Tricuspid valve c) Aortic valve d) Pulmonary valve ["Click here for the answer with explanation", "Correct Answer:"] b) Tricuspid valve In this procedure, de Vega’s annuloplasty ring is sewn at the tricuspid annulus to reduce its dimensions and thereby reducing the leak which occurs mostly because the valve leaflets do not touch each other when the enlarged right ventricle contracts. The post Cardiology MCQ 319: de Vega’s annuloplasty appeared first on Cardiophile MD.

What is Windkessel effect? Cardiology Basics
The term ‘Windkessel effect’ is used in the setting of large elastic arteries like aorta. Elastic arteries  have elastic tissue much more than the muscular arteries and are located nearer to the heart. Elasticity helps these blood vessels to maintain a relatively constant pressure gradient and flow though, the heart is pumping only intermittently. The original term ‘Windkessel’ means ‘air chamber’ in German language. It was an air chamber used in fire engines in the 18th century, to maintain continuous delivery of water for fire-fighting. In the case of aorta, the aortic elasticity causes expansion and te...

What is dobutamine stress echocardiography? Cardiology Basics
Usual stress test for the heart is exercise ECG in which serial ECG recordings are done during a graded exercise protocol, usually on a treadmill. There are certain conditions like left bundle branch block in which an exercise ECG becomes uninterpretable. Some persons are unable to exercise on a treadmill due to illness or disability. In such situations dobutamine infusion is given instead of exercise, to increase heart rate and myocardial contractility, thereby increasing the workload of myocardium. Echocardiograms are taken then to assess the response of the myocardium to stress. This is known as dobutamine stress echoc...

What is the difference between CRT-P and CRT-D? Cardiology Basics
In cardiology, CRT stands for cardiac resynchronization therapy. CRT is used in heart failure with reduced ejection fraction. According to the Universal Definition and Classification of Heart Failure, heart failure with reduced ejection fraction has left ventricular ejection fraction of 40% or less. CRT is a type of pacemaker in which three chambers of the heart are paced, right atrium, right ventricle and left ventricle. This picture illustrates what reduced ejection fraction means. Ejection fraction is the fraction of end diastolic volume which is pumped out from the left ventricle during systole. Normal ejection fracti...

What are ventricular ectopic beats (VPC)? Cardiology Basics
Ventricular ectopic beats are premature heart beats originating from the ventricles. Normal heart beats originate from the sinus node, situated in the upper part of right atrium. Sinus node is the natural pacemaker of the heart which gives out regular impulses to induce sequential contractions of atria and ventricles. Ventricular ectopic beats (VEB) are also known by other names like ventricular premature beat (VPB), ventricular premature complex (VPC) and premature ventricular complex (PVC). Ventricular ectopic is the commonest form of cardiac arrhythmia. In a ventricular ectopic beat, the sequence of activation is diffe...

What is pacemaker syndrome? Cardiology Basics
Pacemaker syndrome is a group of symptoms which can occur in a person implanted with a single chamber ventricular pacemaker. In the normal heart, atria contract first to give a booster filling for the ventricles, followed by the contraction of the ventricles. This is known as atrioventricular (AV) synchrony. When a single chamber pacemaker paces the right ventricle, this AV synchrony is lost and may cause symptoms of pacemaker syndrome. Persons with pacemaker syndrome may have exertional breathlessness, hypotension and syncope. Easy fatigability, sensation of fullness and pulsations in the head and neck are also features ...

MDM of mitral stenosis is a “ mid diastolic misnomer ”
Nearly a century ago, Carl Wiggers helped us understand the dynamics of cardiac cycle with a historical diagram depicting systole and diastole. We know diastole has 4 phases. They are  IVRT(nil)  early rapid filling,(70%) diastasis,(0-5%) atrial contraction(25%) (Percentage filling within the brackets) What is mid diastole? The easiest way to define mid diastole is to divide diastole into three parts with reference to time and call the mid-third as mid-diastole. (.5 seconds/ divided by 3). But, Physiologically we can’t do that. Even hemodynamically there is no distinct mid diastole as diastole is di...

Cardiology update: Should mRNA vaccine myocarditis be a contraindication to future COVID-19 vaccinations ?
BY ANISH KOKA Myopericarditis is a now a well reported complication associated with Sars-Cov-2 (COVID-19) vaccinations. This has been particularly common with the messenger RNA (mRNA) vaccines (BNT162b2 and mrna-1273), with a particular predilection for young males. Current guidance by the Australian government “technical advisory groups” as well as the Australian Cardiology Society suggest patients who have experienced myocarditis after an mRNA vaccine may consider a non-mRNA vaccine once “symptom free for at least 6 weeks”. A just published report of 2 cases from Australia that document myopericarditi...

Cardiology EHR Selection Checklist for Small Practices
Software developers have been working hard the past couple of years to be ready for the heightened interest in EMR/EHR systems. The initial focus was on "generic" systems that could work in various practices. Basic functionality isn't always enough to impress medical offices – especially medical specialists such as cardiologists. The Certification Commission for Health Information Technology, a nonprofit group that vets EHR systems for compliance with performance standards, has also noted that a one-size-fits-all approach to electronic health records does medical practices a disservice. Knowing what features you need and...

Does the Aortic root contract or relax during ventricular systole ?
Some time back I asked this question in one of my classes for the fellows and found no takers. Not even a guess? I realized later it was indeed a tough question. The heart is not the only dynamic organ as we generally believe. The entire aorta which is the extension of the left ventricle has to be dynamic according to the physics of ventricular-arterial coupling and the momentum of blood flow. What happens to the aortic dimension with systole? Even prior to systole, there is evidence, Aorta gets ready to receive the blood from the LV. So, the Aortic root is larger at the onset of systole. (Ref 2 It is been g...

New post up on Cardiology Medscape: Lessons learned from the failure of Renal denervation for high blood pressure
Most people come by it honestly. They eat too much, move too little, skimp on sleep, take on too much stress and then succumb to buying larger clothes. The word we use in medicine is insidious. High blood pressure (hypertension – HTN) is one of the leading cardiovascular problems of this time. Some have called treating HTN the holy grail of medicine. Think about why this may be. The human heart contracts 100,000 times per day. Each beat delivers a pressure load to the thousands of arteries in the body. Over days, weeks, months, years and decades, small elevations of high pressure can have devastating wear and tear ef...

Let ’s Put The Best To The Test: Our KardiaMobile6L Review
AliveCor is close to our hearts. Literally. David Albert, the co-founder of the company, started experimenting with handheld, wireless ECG devices in the late 90s. Approximately 10 years later we tried out their FDA-cleared, medical grade gadget. It was a truly inspiring moment. Needless to say, we’ve been keeping track of their journey ever since. In our eyes Kardia is the textbook example of technology shaping health care, empowering and supporting not only e-patients, but medical professionals as well. So, let’s take a look at their newest creation, the KardiaMobile6L! Why did the chicken cross the road? T...
