Journal ArticleDOI
Cardiovascular magnetic resonance, fibrosis, and prognosis in dilated cardiomyopathy
Ravi Assomull,Sanjay K Prasad,Jonathan Lyne,Gillian Smith,E. Burman,Mohammed Khan,Mary N. Sheppard,Philip A. Poole-Wilson,Dudley J. Pennell +8 more
TL;DR: In DCM, midwall fibrosis determined by CMR is a predictor of the combined end point of all-cause mortality and cardiovascular hospitalization, which is independent of ventricular remodeling, which suggests a potential role for CMR in the risk stratification of patients with DCM.
Journal ArticleDOI
Cardiovascular Magnetic Resonance in Cardiac Amyloidosis
Alicia M. Maceira,Jayshree Joshi,Sanjay K Prasad,James C. Moon,Enrica Perugini,Idris Harding,Mary N. Sheppard,Philip A. Poole-Wilson,Philip N. Hawkins,Dudley J. Pennell +9 more
TL;DR: In cardiac amyloidosis, CMR shows a characteristic pattern of global subendocardial late enhancement coupled with abnormal myocardial and blood-pool gadolinium kinetics and may prove to have value in diagnosis and treatment follow-up.
Journal ArticleDOI
Association of fibrosis with mortality and sudden cardiac death in patients with nonischemic dilated cardiomyopathy.
Ankur Gulati,Andrew Jabbour,Tevfik F Ismail,Kaushik Guha,Jahanzaib Khwaja,Sadaf Raza,Kishen Morarji,Tristan D.H. Brown,Nizar Ismail,Marc R. Dweck,Elisa Di Pietro,Michael Roughton,Ricardo Wage,Yousef Daryani,Rory O'Hanlon,Mary N. Sheppard,Francisco Alpendurada,Alexander R. Lyon,Stuart A. Cook,Martin R. Cowie,Ravi Assomull,Dudley J. Pennell,Sanjay K Prasad +22 more
TL;DR: Risk stratification of patients with nonischemic dilated cardiomyopathy is primarily based on left ventricular ejection fraction (LVEF), and superior prognostic factors may improve patient selection for implantable cardioverter-defibrillators (ICDs) and other management decisions.
Journal ArticleDOI
Current state of knowledge on Takotsubo syndrome: a Position Statement from the Taskforce on Takotsubo Syndrome of the Heart Failure Association of the European Society of Cardiology
Alexander R. Lyon,Eduardo Bossone,Birke Schneider,Udo Sechtem,Rodolfo Citro,S. Richard Underwood,Mary N. Sheppard,Gemma A. Figtree,Gemma A. Figtree,Guido Parodi,Yoshihiro J. Akashi,Frank Ruschitzka,Gerasimos Filippatos,Alexandre Mebazaa,Elmir Omerovic +14 more
TL;DR: Novel structured approaches to diagnosis, risk stratification, and management are presented, with new algorithms to aid decision‐making by practising clinicians in the management of complex cases with ongoing symptoms after recovery, recurrent episodes, or spontaneous presentation.
Journal ArticleDOI
Prognostic significance of myocardial fibrosis in hypertrophic cardiomyopathy.
Rory O'Hanlon,Agata Grasso,Michael Roughton,James C. Moon,Susan J. Clark,Ricardo Wage,Jessica Webb,Meghana Kulkarni,Dana Dawson,Leena Sulaibeekh,Badri Chandrasekaran,Chiara Bucciarelli-Ducci,Ferdinando Pasquale,Martin R. Cowie,William J. McKenna,Mary N. Sheppard,Perry M. Elliott,Dudley J. Pennell,Sanjay K Prasad +18 more
TL;DR: In patients with HCM, myocardial fibrosis as measured by late gadolinium enhancement cardiovascular magnetic resonance is an independent predictor of adverse outcome.
