Comment on Multicenter Assessment of the Reproducibility of Volumetric Radiofrequency-Based Intravascular Ultrasound Measurements in Coronary Lesions that Were Consecutively Stented by Paul Schoenhagen

Paul Schoenhagen — Mon, 30 Jan 2012 23:27:13 +0000

The author stated that “significant differences for both geometrical and compositional measurements were seen”.

Importantly, some of the plaque components defining ‘vulnerable plaques, specifically necrotic core “showed on average, the highest measurement reproducibility”.

The findings of OCT are over two fold of IVUS?

Comment on Utility of Cardiovascular Magnetic Resonance in Identifying Substrate for Malignant Ventricular Arrhythmias by Juan Batlle

Juan Batlle — Wed, 25 Jan 2012 03:44:42 +0000

The authors claim CMR provides robust identification of myocardial disease in patients with SCD or SMVT. Since half of the patients were reassigned to a new category, this is evidence that cardiac MRI should become an essential tool in the evaluation of malignant arrhythmias.

Comment on Resting Coronary Flow Velocity in the Functional Evaluation of Coronary Artery Stenosis: Study on Sequential Use of Computed Tomography Angiography and Transthoracic Doppler Echocardiography by Paul Schoenhagen

Would be interesting to compare to CT FFR as describe in e.g.:

Comment on Reference Values for Normal Pulmonary Artery Dimensions by Noncontrast Cardiac Computed Tomography: The Framingham Heart Study by Jacobo Kirsch

Jacobo Kirsch — Tue, 24 Jan 2012 03:11:52 +0000

Important information (in a large group of patients) to back up what we knew.

Comment on Patient Management After Noninvasive Cardiac Imaging – Results From SPARC (Study of Myocardial Perfusion and Coronary Anatomy Imaging Roles in Coronary Artery Disease) by Jacobo Kirsch

Jacobo Kirsch — Tue, 24 Jan 2012 03:08:52 +0000

Clearly, the question is why are we performing non-invasive testing at all?
Dr. Batlle recently said in an earlier post that: “patients and physicians are unhappy with ‘no-imaging’ strategies!”.
Interestingly, more cats were done after CTA than after other modalities. Are our false positive rates statistically higher?

Comment on Using Stress Testing to Guide Primary Prevention of Coronary Heart Disease Among Intermediate-Risk Patients A Cost-Effectiveness Analysis by Juan Batlle

Juan Batlle — Mon, 23 Jan 2012 20:23:53 +0000

Useful information that helps confirm our suspicions! We all know however, that patients and physicians are unhappy with “no-imaging” strategies! It may also be more effect to stratify patients like this with a calcium score, as there is a better plausible relationship between Ca score and need for statins. It is also less burdensome and technically challenging than an EKG stress and can reliably identify many patients with no calcified plaque, who are therefore at very low risk.
