A Rare but Deadly Complication of Transcatheter Aortic Valve Replacement.

We present a rare case of delayed coronary artery obstruction following a transcatheter aortic valve replacement (TAVR). Interestingly, the patient did not meet the criteria for traditionally recognized risk factors for delayed coronary obstruction. This case piques interest as to whether the severity of calcification on aortic valve leaflets plays any role in coronary obstruction post transcatheter aortic valve replacement.

Infective Endocarditis in Hemodialysis Patients.

Background And Aim Of The Study: Infective endocarditis (IE) is a major cause of morbidity and mortality in patients with end-stage renal disease (ESRD). The study aim was to evaluate the demographic, clinical, microbiological and inpatient mortality data of IE in hemodialysis patients.

Methods: Data were analyzed for all IE patients admitted to the authors' 800-bed tertiary care hospital between January 2001 and December 2014.

Fragmented ECG as a risk marker in cardiovascular diseases.

Various noninvasive tests for risk stratification of sudden cardiac death (SCD) were studied, mostly in the context of structural heart disease such as coronary artery disease (CAD), cardiomyopathy and heart failure but have low positive predictive value for SCD. Fragmented QRS complexes (fQRS) on a 12-lead ECG is a marker of depolarization abnormality. fQRS include presence of various morphologies of the QRS wave with or without a Q wave and includes the presence of an additional R wave (R') or notching in the nadir of the R' (fragmentation) in two contiguous leads, corresponding to a major coronary artery territory.
