The FDA has given thumbs up to two clinical studies for a transcatheter aortic valve replacement (TAVR) system developed by HLT Inc. to treat aortic stenosis among high-risk patients. Those studies will include aortic regurgitation which also occurs when an aortic valve doesn't open and close tightly enough but for which there are few suitable, noninvasive treatments.

Valuations in the med-tech space lately call into question the old medical adage: “If you hear hoofbeats, think horses.” These days, you would be wise to consider unicorns in the differential diagnosis. Two new companies achieved the formerly rare status just this week. Viz.ai Inc.’s closing today of a $100 million series D financing propelled it into the stratosphere with a $1.2 billion valuation, joining Bostongene LLC which completed its own $150 million round Wednesday.

As was the case with left atrial appendage closure, renal denervation (RD) as a treatment for hypertension has proven to be difficult to move along into routine clinical usage. New data for a study sponsored by Medtronic plc showed that RD offers a statistically significant improvement over sham treatment in reducing hypertension, but the data do not seem to suggest that patients will be able to drop their antihypertensive medications after RD treatment.

The tricuspid valve at times seems the lost child of the heart’s valves, but new research hints that regurgitation of this valve can be resolved with a transcatheter replacement. Adam Greenbaum, of Emory University School of Medicine, said the early feasibility study of the Pascal valve by Edwards Lifesciences Inc., of Irvine, Calif., demonstrated a large improvement in mortality at one year and significant improvements in heart failure status, a result that offers new hope for these patients.

There has been some skepticism about the value of electronic health records (EHRs) beyond their role as a source of income for EHR developers, but an April 3 presentation at the 2022 America College of Cardiology scientific sessions being held in Washington suggests this type of software offers some real value for heart failure patients. Tariq Ahmad of Yale School of Medicine said a study of EHRs suggests their power lay in part in prompting compliance with heart failure medication regimes, an application of this type of software that can both save lives and cut costs for the Medicare program and Medicare beneficiaries.

Pharmaceutical agents took center stage in Washington on the first full day of the 2022 scientific sessions of the American College of Cardiology, such as an April 2 presentation on the use of the mavacamten for obstructive hypertrophic cardiomyopathy (OHC). Milind Desai of the Cleveland Clinic said 16-week data for this cardiac myosin inhibitor showed well in reducing heart failure class status, but there are data arising from studies in China which suggest that radiofrequency (RF) ablation might also work for these patients.

Eko Devices Inc. launched a redesigned app and smart stethoscope system to detect heart disease during a regular physical, potentially reducing the time to diagnosis and treatment for America’s number one killer. The system incorporates artificial intelligence (AI) to identify heart murmurs and atrial fibrillation with performance the company says is on par with cardiologists.

Norwegian diagnostics company Cardinor AS landed a CE mark for its Secretoneurin (SN) ELISA (enzyme-linked immunosorbent assay). The blood-based test detects SN, a small 33-amino acid neuropeptide produced by neuroendocrine and heart muscle cells. Studies have shown the biomarker is a predictor of mortality in major patient cohorts, including ventricular arrhythmia, acute heart failure, acute respiratory failure patients with cardiovascular disease (CVD) and severe sepsis.

For about one-third of stroke patients, the cause of their cerebrovascular accident (CVA) is unknown at the time of hospitalization, but crucial to determine to prevent subsequent strokes. Electrocardiogram (ECG) monitoring in the 24 to 48 hours after a stroke detects atrial fibrillation (AF) in about 5% of patients. Remote monitoring with a noninvasive device detects far more cases and provides the opportunity to quickly head off secondary strokes, preserving lives and reducing costs of care, according to a study published by Royal Philips NV researchers.

Royal Philips NV expanded its commitment to increasing awareness of cardiovascular implantable electronic device (CEID) infections with a new partnership with the American Heart Association (AHA). The organizations are rolling out a program to educate medical professionals on the proper management of these infections which are commonly treated with antibiotics, an approach that leads to reinfection in the majority of cases.
