Dyspnea After Pulmonary Embolism: Optimal Medical Therapy in Peripheral Vascular Disease
Guest: Stan Henkin, M.D.
Host: Malcolm R. Bell, M.D.
Historically, majority of clinical and research focus has been on acute management of pulmonary embolism (PE). However, long-standing functional impairment after PE is common, occurring in up to 50% of individuals with history of PE. This is termed post-PE syndrome – an underrecognized, underdiagnosed, and undertreated entity. In this podcast, experts discuss epidemiology, pathophysiology, diagnosis, and treatment of post-PE syndrome.
Topics Discussed:
What is Post-PE syndrome? How common is it?What is your suggested work-up of patient who presents with dyspnea after PE?When should a patient be referred to a tertiary/expert center?Connect with Mayo Clinic's Cardiovascular Continuing Medical Education online at https://cveducation.mayo.edu or on Twitter @MayoClinicCV and @MayoCVservices.

An AI-ECG Algorithm for Left Ventricular Diastolic Dysfunction
Guest: Jae Oh, M.D.
Host: Anthony H. Kashou, M.D.
Diastolic function assessment is crucial in diagnosing, managing, and predicting outcomes in various cardiac conditions. It provides insight into heart health, particularly in diagnosing heart failure. Shortness of breath, a common patient complaint, often indicates elevated diastolic filling pressure if linked to a cardiac condition. Echocardiography is the primary method for assessing diastolic function, but it is operator-dependent and not always available. In contrast, ECGs are standardized and widely accessible. Although subtle changes in ECGs are not easily detectable by the human eye, artificial intelligence can identify specific conditions reflected in the ECG. By training an AI model with labeled ECGs based on diastolic function determined through echocardiography, researchers achieved high accuracy in detecting diastolic dysfunction. AI-enhanced ECGs can significantly impact the identification of both asymptomatic and symptomatic cardiac conditions, potentially streamlining diagnostic strategies and reducing costs. Future developments may enable patients to monitor their heart health using simple wearable devices, enhancing the management of heart failure and other conditions.
Topics Discussed:
Your special clinical academic interest is echocardiography. Why are you interested in ECG AI in diastolic function?What is diastolic function and why is it important to assess diastolic function in clinical practice?Why did you decide to create AI-ECG for diastolic function assessment?What did you find and how do you envision AI ECG for diastolic function be used in clinical practice?Connect with Mayo Clinic's Cardiovascular Continuing Medical Education online at https://cveducation.mayo.edu or on Twitter @MayoClinicCV and @MayoCVservices.

3D Visualization of the Heart in Immersive Technology Like Mixed Reality
Guest: Dr. Klaudia Proniewska
Host: Anthony H. Kashou, M.D.
The most commonly applied way of teaching students the foundations of human anatomy and physiology involves textbooks and lectures. This method of transmitting knowledge causes difficulties for students, especially in the context of three-dimensional imaging of organ structures, and as a consequence, translates into difficulties with imagining them. Even with the rapid uptake of knowledge dissemination provided by online materials, including courses and webinars, there is a clear need for learning programs featuring first-hand immersive experiences tailored to individual study paces. In my research, I present an approach to enhance a classical study program by combining multi-modality data and representing them in a Mixed Reality (MR)-based environment. The advantages of the proposed approach have been proven by the conducted investigation of the relationship between heart anatomy, its electrophysiological characteristics, and resulting wave morphology on the electrocardiogram (ECG). Another part of the research focuses on the role of the anatomy of the heart, e.g., the sinoatrial node, in ECG formation, while the MR-based visualization of combined imaging data with non-invasive CineECG (by Peter van Dam) imaging demonstrates the educational application of these advanced technologies for teaching cardiac anatomy and ECG correlations.
Topics Discussed
Can you explain why three-dimensional structures are important to teach electrophysiology of the heart?How does the electrocardiogram (ECG) relate to heart anatomy, and why is this relationship fundamental in understanding cardiac electrophysiology? Give an example.Have you implemented any innovative teaching methods or technologies to enhance the learning experience in cardiac anatomy and electrophysiology? If so, can you describe their impact?In your experience, what are the most effective ways to convey complex 3D structures and dynamic processes in cardiac anatomy and electrophysiology to students or professionals?Connect with Mayo Clinic's Cardiovascular Continuing Medical Education online at https://cveducation.mayo.edu or on Twitter @MayoClinicCV and @MayoCVservices.

Genomics in Inflammatory Cardiomyopathies
Guest: Naveen L. Pereira, M.D.
Hosts: Kyle W. Klarich, M.D
Patients with heart failure and ventricular arrhythmias can have inflammatory heart disease such as myocarditis or sarcoidosis. The diagnosis is typically made by imaging studies including cardiac MRI and PET scans. However, it is critical to performed genetic testing in such patients given that genetic cardiomyopathy can often present as an inflammatory heart disease phenotype which may have important prognostic and therapeutic implications.

Understanding ECG Waveforms: Normal vs. Abnormal
Guest: Dr. Peter van Dam
Host: Anthony H. Kashou, M.D.
The ECG interpretation is majorly driven by event detection, i.e. QRS onset and end, QT time, P wave etc. From these we can determine the normal heart rhythm, and some performance measures, like heart rate etc. The ECG waveforms, however, are much less understood. This is a pity, as ECG waveforms, provide instantaneous information on the electrophysiological and structural function of the heart. In this respect it is interesting to know if there is something like a normal ECG waveform or normal PathECG (CineECG). This latter technique is a vector-based method to estimate the electrical position of a moving vector within the heart. Similar normal distributions can be created to compare to the normal ECGs.
Topics DiscussedHow can we define a normal ECG waveform? (ECGs from healthy normal people for different age groups, I used about 6000 normal ECGs, correction for heart rate by resampling to standard QT time (400 ms for instance, these ECGs can be used to create a distribution of amplitudes and derived signals (CineECG) to compare an ECG too)What is needed for an accurate waveform comparison? (Good baseline correction, not filtering, but baseline correction) What is the onset and end of the P-wave, QRS and T wave?)Are normal ECGs waveforms different from abnormal ECG waveforms? (Of course they overlap, describe left bundle branch block, or ischemia, with long QRS or deviating ST segment )Did you use this method to classify ECGs as normal or abnormal? (results from our study (manuscript in preparation) that any QRST sequence in an ECG can be classified as abnormal with an accuracy (AUC) of more than 81%. In our study population 15% of the patients had only atrial related abnormal ECGS)Connect with Mayo Clinic's Cardiovascular Continuing Medical Education online at https://cveducation.mayo.edu or on Twitter @MayoClinicCV and @MayoCVservices.
