Transcatheter Aortic Valve Implantation in the Descending Aorta: History Revisited!

An elderly patient with significant aortic regurgitation presented with heart failure. Dilation of the aortic root precluded a transcatheter anatomic site valve implantation, and prohibitive operative risk ruled against surgical implantation. A bail-out transcatheter implantation of the aortic valve in the descending aorta was successfully carried out with satisfactory outcomes.

'Egg-cased heart': a multimodality imaging approach to chronic constrictive pericarditis with egg-shell calcification: a case report.

BACKGROUND: Constrictive pericarditis (CP), also known as Pick's disease, is a sequela of chronic inflammation of the pericardium. Pericardial calcification is a common occurrence in CP; however, extensive egg-shell like calcification is rare. Our case, highlights, how a multi-modality imaging in a middle aged female helped to diagnose chronic constrictive pericarditis (CCP) with egg-shell like calcification encasing the heart. CASE SUMMARY: Middle aged female with features of right heart failure, was diagnosed as CP based on two-dimensional echocardiography and cardiac catheterization. Computed tomography (CT) scan chest showed extensive egg-shell like calcification encasing the heart, suggestive of calcific CP. Subsequently, she underwent pericardiectomy, through median sternotomy approach and is currently on follow-up with asymptomatic cardiac status. DISCUSSION: Extensive pericardial calcification encasing the heart like an egg-shell is rare in CCP. Likelihood of incomplete pericardial resection is high in calcific CP and hence a median sternotomy is preferred over anterolateral thoracotomy. A preoperative non-contrast CT scan defines the thickness, anatomic extent the calcification and its adherence to myocardium and surrounding structures. A reconstructed volume-rendered image delineates the extent of calcification precisely, thus determining the optimum surgical approach. A multi-modality imaging in CP, especially in calcific CP, is thus of paramount importance.

Prognostic significance of Troponin I in patients undergoing primary percutaneous coronary intervention.

This observational study investigates the prognostic significance of troponin I in patients undergoing primary percutaneous intervention (pPCI). Sequential cardiac biomarker sampling of the enrolled patients (n = 167) was performed on admission and at 6,12,24 and 48 h. Clinical characteristics, major adverse cardiac and cerebrovascular events (MACCE) (death, reinfarction, stroke and new or worsening heart failure) and left ventricular ejection fraction (LVEF) were noted on admission and 30 day follow-up. A 24-h troponin I level >60 ng/ml predicted MACCE (OR 4.06, p = 0.023; adjusted OR 5.09, p = 0.034) and less than 10% improvement in LVEF on follow-up (OR 2.49, p = 0.007). Thus, in patients undergoing pPCI, 24-h cardiac Troponin I is a good non-invasive surrogate to predict MACCE and improvement in LVEF.
