Optimizer System for Cardiac Contractility Modulation: Interview with Dr. Ishu Rao, Medical Director of Impulse Dynamics
Impulse Dynamics, based in Mt. Laurel, New Jersey, has developed the Optimizer system, a device designed to improve myocardial contractility in patients with heart failure. The system is intended to improve the quality of life of heart failure patients by reducing the severity of their symptoms. At present, many heart failure patients have few options in terms of effective treatments to reduce and control their symptoms. Medication can help certain patients, but some still experience unacceptable symptoms. Pacemakers, which correct the heart’s rhythm, are beneficial for some, but not all patients, and they do not incr...

Why ventricular tachycardia has wide QRS complex ?
Why VTs have wide QRS complex? Brief answer: VT  usually presents with wide QRS tachycardia because it originates in ventricular myocardium, travels muscle to muscle instead of the normal conduction system. However, VTs need not be wide always, if it captures the conduction system early and more proximally it can be as narrow as SVT. Further reading: Only for cardiology fellows  Two empirical statements are made here. (The scientific chances of both being reasonably correct are fair) 80 % of wide QRS tachycardia by default is VT. That means 20 % of wide QRS is not VT. We all accept that. 80 % of narrow QRS tachycardia i...

Barostim Neo Neuromodulation Device for Heart Failure Wins FDA Approval
CVRx, a Minneapolis, Minnesota company, won FDA approval for the first neuromodulation device designed to address heart failure. Intended as a treatment option for patients with an ejection fraction ≤35% and New York Heart Failure Classification of III or II (with recent history of Class III), the device stimulates the carotid artery and in turn the baroreceptors that control cardiovascular activity. The system monitors and adjusts the signals it delivers to achieve optimal beat-to-beat stimulation. It has been approved in Europe for a number of years (see flashbacks below). “With the FDA’s approval of the...

Security Crisis of Cardiac Pacemakers Paves the Way for IoT Security Evolution in Cardiology
Conclusion Fortunately, there have been no malicious activities or attacks in which hackers tampered with pacemakers, programmers, or other cardiac devices so far. However, the possibility itself is critical enough to prioritize the security assurance of connected cardiology devices. The security crisis associated with cardiac devices might have hindered their adoption, yet it also pointed to a critical gap in policy-making and technology testing on the whole. While some measures are underway, fully bridging this gap will require a more coordinated effort from both regulators and manufacturers. Inga Shugalo is a...

Attain Stability Quad MRI SureScan, World ’s Only Active Fixation Left Heart Lead, Approved in U.S.
Cardiac resynchronization therapy (CRT) devices are implanted into heart failure patients to try to improve the efficiency of the heart. How well the therapy ends up working depends very much on the positioning of the electrodes of the leads that stretch into the heart. Quadripolar leads, having two more electrodes than typical, provide a great deal of control to cardiologists to stimulate the heart from different spots, but they typically still suffer from too much physical movement. Medtronic just won FDA approval for the Attain Stability Quad MRI SureScan left heart lead that’s used with the company’s quadri...

Investigations and management of dilated cardiomyopathy
Investigations in dilated cardiomyopathy Chest X-ray PA view will assess the cardiac size in dilated cardiomyopathy and show evidence of pulmonary congestion. Sick persons may present with features of frank pulmonary edema in the form of hilar haze or bat wing pattern of pulmonary edema. Significant left ventricular dysfunction can exist without much of cardiomegaly on chest X-ray as well. ECG may show sinus tachycardia, left atrial overload and sometimes left ventricular hypertrophy. A wide QRS complex with left bundle branch block pattern may indicate potential benefit from cardiac resynchronization therapy (CRT). ECG ...

First Cardiac Contractility Modulation Device Approved by FDA
Most cardiac implants, such as pacemakers and AICDs, are designed to correct the underlying heart’s rhythm, and synchronize atrial and ventricular contractions. That’s how these devices can improve cardiac performance in people with heart failure. They don’t do anything to boost the intrinsic myocardial contractility of the heart. Now the FDA has just given approval to the first implant that actually uses electrical pulses to improve how hard the heart pushes blood through the body. The Optimizer Smart system from Impulse Dynamics, a company out of Orangeburg, New York, is implanted like any cardiac implant, ...

BIOTRONIK Wins FDA Approval for Two High-Voltage Families of Cardiac Implants
The FDA has given BIOTRONIK approval to introduce the company’s Acticor and Rivacor lines of high-voltage cardiac rhythm implants. They’re designed to treat tachycardia (likely supraventricular tachycardia (SVT) and have been made to be smaller and have a longer battery life. Some of the implants have a nearly 15 year lifetime, helping to lower the number of replacement procedures. All of the implants are 3 Tesla MR-conditional, meaning that patients can undergo most MRI scans as long as certain precautions are taken. BIOTRONIK touts the shape of the implants, which are supposedly less irritating on tissues. Th...

Mitral E/E ’ for assessment of left ventricular diastolic function
Mitral E/E’ for assessment of left ventricular diastolic function Mitral E/E’ for assessment of left ventricular diastolic function E/E’ measured using a combination of mitral flow Doppler and tissue Doppler of mitral annulus is an important measure of left ventricular diastolic function. Assessment of diastolic function of the left ventricle is assuming more importance after the recognition of diastolic heart failure which is otherwise known as heart failure with preserved ejection fraction (HFpEF). As the population ages, frequency of HFpEF is on the rise. The image illustrates measurement of E’ b...

Coronary artery and veins are married life long . . . with a purpose !
Cardiologist are always worried about the supply side of coronary blood flow. It’s fair enough, we can condone our brain for this one way thinking , afterall arterial supply remain the life-line for the heart. Some of us could (should) realise the importance of these  humble coronary veins which are anatomically and physiologically tied together.Its existence is as unique as their arterial counterpart.Coronary blood flow of about 250 ml traverses both the arms every minute.Imagine the scenario if the veins refuse to clear the blood from previous cardiac cycle . . . total hemodynamic chaos right ? Luckily such s...
