- CONCLUSIONS: The proposed method shows reliable performance on the segmentation of heart sounds. Compared with previous works, this method can be applied to not only normal heart sounds, but also the sounds with S3, S4 and murmurs, thus greatly increasing the applied range.
- Simple risk model and score for predicting of incident atrial fibrillation in Japanese. [Journal Article]
- JCJ Cardiol 2018 Jul 28
- CONCLUSIONS: We developed 7-year risk scores for incident AF using usually available clinical factors including ECGs in primary care. These risk scores could identify individuals with high risk of incident AF at health check-up and outpatient clinics.
- Murmur clinic: validation of a new model for detecting heart valve disease. [Journal Article]
- HHeart 2018 Jul 26
- CONCLUSIONS: Most patients in a specialist murmur clinic had normal auscultation and point-of-care scans and no additional valve disease was detected by standard echocardiography. This suggests that a murmur clinic is a valid model for reducing demand on hospital echocardiography services.
- Heart murmurs and echocardiography findings in the normal newborn nursery. [Journal Article]
- CHCongenit Heart Dis 2018 Jul 24
- CONCLUSIONS: The use of echocardiography in the normal newborn nursery has increased with time despite improved prenatal detection of heart disease and the use of pulse oximetry screening, and identifies significant heart disease in a small but important number of infants.

Cardiac murmurs were first described approximately 200 years ago. Subsequently, various clinicians, starting with Samuel Levine, have proposed grading schemes, depicting intensity, or other murmur characteristics, in an attempt to differentiate pathological and physiological murmurs or different degrees of pathology. In the 1960s, these schemes were adapted by veterinary cardiologists and have been used over the last 50 years. However, the clinical utility of these schemes has only recently been examined in veterinary medicine (and never examined in humans), and these studies suggest that the current, commonly used murmur grading scheme is unnecessarily complex and contains redundant information. A simpler, more intuitive grading scheme might achieve the same desired outcome as the more complex scheme, potentially with less confusion. This review examines the history of murmur grading and proposes a reconsideration of the current grading scheme to improve clinical communication.

Extrinsic pulmonary artery stenosis caused by anterior mediastinum teratoma presenting with an ejection systolic murmur is a rare phenomenon. Till date, 15 cases have been reported (inclusive of this case) in the English literatures. Herein we report a 20 year old female with extrinsic pulmonary artery stenosis because of compression by an anterior mediastinal teratoma with a loud ejection systolic murmur. The case report aims to highlight the awareness of such rare presentation of anterior mediastinal teratomas that may mimic congenital valvular heart diseases among clinicians.

: In this paper, we accurately detect the state-sequence first heart sound (S1) - systole -second heart sound (S2) - diastole, i.e. the positions of S1 and S2, in heart sound recordings. We propose an event detection approach, without explicitly incorporating a priori information of the state durations. This renders it also applicable to recordings with cardiac arrhythmia and extendable to the detection of extra heart sounds (third and fourth heart sound), heart murmurs, as well as other acoustic events. : We use data from the 2016 PhysioNet/CinC Challenge, containing heart sound recordings and annotations of the heart sound states. From the recordings, we extract spectral and envelope features and investigate the performance of different deep recurrent neural network (DRNN) architectures to detect the state-sequence. We use virtual-adversarial training (VAT), dropout and data augmentation for regularization. : We compare our results with the state-of-the-art method and achieve an average score for the four events of the state-sequence of F 96% on an independent test set. : Our approach shows state-of-the-art performance carefully evaluated on the 2016 PhysioNet/CinC Challenge dataset. : In this work, we introduce a new methodology for the segmentation of heart sounds, suggesting an event detection approach with DRNNs using spectral or envelope features.
