The Use of Romhilt-Estes Criteria in the Presumptive Electrocardiographic Diagnosis of Left Ventricular Hypertrophy in Comparison to Voltage-Based Criteria.

Background The ECG diagnosis of left ventricular hypertrophy (LVH) has been challenging for over a hundred years. ECG diagnosis of LVH has shown good specificity but lacks sensitivity. In addition, voltage-based criteria can be affected by multiple conditions such as obesity and chronic lung disease.

Findings of prosthetic valve endocarditis in the balloon-expandable trans-catheter aortic valve: review of the literature and tips of management.

Prosthetic valve endocarditis after transcatheter aortic valve implantation (TAVI) is a rare complication associated with a high mortality rate. Nonetheless, the rapid expansion of TAVI in recent years has proportionally increased the number of patients exposed to the risk of developing transcatheter valve infection. A 71-year-old female with recent history of TAVI was diagnosed with prosthetic valve obstruction secondary to endocarditis.

A case report of open-aorta, direct transcatheter valve-in-valve implantation: an innovative approach to manage the hazard of coronary flow compromise in transcatheter aortic valve re-interventions.

Background: Coronary flow compromise is a significant risk of transcatheter aortic valve therapy. Warranting preservation of coronary flow is even more challenging with transcatheter aortic valve re-intervention since the implantation of a transcatheter valve within a degenerated bioprosthetic or transcatheter valve increases significantly this hazard.

Case Summary: We present a case of heart failure secondary to transcatheter aortic valve degeneration requiring a transcatheter aortic valve re-intervention.
