Bangladesh News  


Cardiologist Dr Christopher Overgaard said Barton's heart was too weak for open-heart surgery. So, the doctor asked if he'd be interested in trying something new.

The TandemHeart takes over for a weak heart when doctors are working on it like fixing a car engine while it’s running, Overgaard said.

“It acts as an artificial pump, sucking the blood out of the body – energising it, then pumping it back in,” said Alan Daly, the Canadian manager for TandemHeart.

"That allowed the rest of the body to get all the perfusion it needed while we're working away on the chamber that is supposed to do that," Overgaard said, CBCnews reported...

Angiographic and Echocardiographic Correlates of Suitable Septal Perforators for Alcohol Septal Ablation in Hypertrophic Obstructive Cardiomyopathy CJC


Myocardial contrast echocardiography during angiography is critical in identifying appropriate septal perforator(s) for alcohol septal ablation (ASA) in patients with hypertrophic obstructive cardiomyopathy. We evaluated whether there were other angiographic and/or echocardiographic markers that might identify patients who are anatomically suitable for ASA.

The Adverse Long-Term Impact of Renal Impairment in Patients Undergoing Percutaneous Coronary Intervention in the Drug-Eluting Stent Era Circulation: Cardiovascular Interventions.


An observational study determining the long-term impact of chronic kidney disease (CKD) on patients undergoing percutaneous coronary intervention at a tertiary cardiac referral center. CKD is associated with poor in-hospital outcomes after percutaneous coronary intervention, but its effect beyond 1 year, particularly in the drug-eluting stent (DES) era, has not been reported.
