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...

Syncope, History of Coronary Disease, and ST Elevation: Should Medics Activate the Cath Lab?
A 60-something male had a syncopal episode. 911 was called. The patient had no complaint of chest pain or shortness of breath. A prehospital ECG was recorded:Limb leadsPrecordial LeadsThere is ST Elevation in V1-V3, and in aVL, with reciprocal ST depression in II, III, and aVF.There is also some ST depression in V5 and V6, and ST elevation in aVR.What do you think?The medics interpreted the ST elevation, with reciprocal ST depression, as STEMI, and activated the cath lab.Note that you cannot see the entire QRS on the prehospital ECG. The R-waves in leads II and III are cut off. The S-waves in V...

Boston Scientific ’s Resonate Cardiac Implants with HeartLogic Predict Adverse Events, Now FDA Approved
Boston Scientific won approval from the FDA and is launching its Resonate line of implantable cardioverter defibrillators (ICD) and cardiac resynchronization therapy defibrillators (CRT-D). The implants include the firm’s HeartLogic diagnostic capability that sends an alarm to the cardiologist if it believes the patient’s heart is exhibiting worse performance, which may lead to a serious event such as an infarct. HeartLogic relies on a number of sensors within the implant that provide data on heart sounds, heart rate, breathing rate and volume, thoracic impedance, as well as the patient’s current phys...

CRT-D better than CRT-P in NIDCM with left ventricular midwall fibrosis
Francisco Leyva and colleagues compared the outcomes of cardiac resynchronization therapy with (CRT-D) or without defibrillation (CRT-P) in non ischemic cardiomyopathy (NIDCM) [1]. Of their 252 patients, 68 had left ventricular midwall fibrosis detected by cardiac magnetic resonance imaging (CMR). It was found that left ventricular mid wall fibrosis was an independent predictory of total mortality, death from pump failure and sudden cardiac death. Maximum follow up period in their study was 14 years. They documented lower total mortality or hospitalization for major adverse cardiac events in those with CRT-D compared with ...

Medtronic ’s Attain Stability Quad MRI SureScan Cardiac Lead Cleared in Europe
Medtronic won CE Mark approval to introduce its Attain Stability Quad MRI SureScan left heart lead in Europe. The device works with the company’s quadripolar cardiac resynchronization therapy-defibrillators (CRT-D) and CRT-pacemakers (CRT-P) and is not only a conduit for electric current, but also a tool for the electricity to better target cardiac tissue. The device features a helix that works kind of like an anchor to secure the lead, adapting to whatever size anatomy each individual patient has. The four electrodes give multiple options for how to stimulate the heart, helping to achieve optimum efficiency and ther...

BIOTRONIK ’s Tiny Quadripolar Cardiac Resynchronization Therapy Pacemaker FDA Approved
BIOTRONIK has obtained an FDA approval for its Edora HF-T QP MR conditional quadripolar cardiac resynchronization therapy pacemaker (CRT-P). It’s tiny, by comparison to similar devices, and features the BIOTRONIK’s MR AutoDetect technology that allows a physician to tell the implant that an MRI exam is coming up and for the device to automatically engage its MRI safety mode during a scan. The implant has a total volume of only 15 cc, making it the smallest MR-conditional CRT-P on the U.S. market. Being a modern pacemaker, it includes wireless monitoring for daily uploads of any unusual events to the patient...

BIOTRONIK ’s New CRT-ICDs Alleviate Atrial Lead Without Sacrificing Diagnostics
BIOTRONIK won FDA approval and is releasing in the U.S. its Intica DX and Intica cardiac resynchronization therapy (CRT)-DX implantable cardioverter defibrillators (ICD). The DX indicator refers to BIOTRONIK’s technology that obviates the necessity of having an atrial lead to monitor the electrical activity in the atrium, a way that cardiologists use to spot atrial fibrillation and other more serious arrhythmic events. The Intica CRT-DX is the first cardiac rhythm management implant that provides atrial signal data without having an atrial lead, which should help reduce complications and make implantation easier, fas...

BIOTRONIK ’s MultiPole Pacing for CRT Defibrillators Now Approved in U.S.
BIOTRONIK won FDA approval for its MultiPole Pacing (MPP) technology to be introduced in the U.S. on its CRT defibrillators (CRT-Ds). It’s designed to address the fact that the hearts of many patients on cardiac resynchronization therapy (CRT) fail to respond properly, and allowing cardiologists more pacing options can help overcome that in many cases. Specifically, the left ventricle can be paced twice per cycle, delivering the pulses either simultaneously or sequentially. The same BIOTRONIK CRT-Ds that feature MPP also sport the company’s ProMRI capability, which lets patients with the implants receive MRI...

Boston Sci ’s Long Lasting Resonate ICDs and CRT-Ds Get FDA Approval
Boston Scientific won FDA approval to introduce its Resonate line of implantable cardioverter defibrillators (ICD) and cardiac resynchronization therapy defibrillators (CRT-D). The same products were approved in Europe via a CE Mark earlier this year. Some of the notable features of the Resonate devices include multi-electrode pacing and integration with the company’s HeartLogic Heart Failure Diagnostic Service, essentially an algorithm that seems to do a good job predicting heart failure events. New battery technology allows Boston Scientific to claim an overall working lifetime for Resonate ICD devices at twice ...

BIOTRONIK Releases New Line of MR-Conditional Pacemakers, CRT-Ps
BIOTRONIK is releasing a new line of MR-conditional pacemakers, the smallest the company has produced, and new quadripolar cardiac resynchronization therapy pacemakers (CRT-P). The Edora devices allow patients to receive MRI exams, as long as certain precautions are taken, and feature MRI AutoDetect feature that automatically puts an implant into safe mode when it’s near an MRI machine. When the scan is done and the patient moves away from the machine, the implant reverts back to its normal functionality. All the Edoras also feature wireless connectivity, unloading its data to BIOTRONIK Home Monitoring system for t...
