Successful Treatment of Severe Paravalvular Leak by Repositioning a Self-Expandable Percutaneous Aortic Valve Bioprosthesis (Evolut PRO+) Using the "Double Snare" Technique.

Significant (moderate or severe) paravalvular leak (PVL) after transcatheter aortic valve replacement (TAVR) remains a common phenomenon and has been associated with decrease survival and quality of life. Transcatheter valve embolization and migration (TVEM) is a rare post-TAVR complication that can occur in 1% of cases and has been associated with worse patient outcomes. Valve embolization or migration into the left ventricle can result in significant PVL causing hemodynamic instability, shock, heart failure, and hemolytic anemia.

: An Uncommon Human Pathogen Causing Infective Endocarditis in a Valve-in-Valve Transcatheter Aortic Valve Replacement.

is a fish pathogen and an uncommon cause of human infections. There is a growing body of evidence showing its potential for causing endocarditis especially in those with prior valve surgery. In this case report, we present what we believe is the first case of endocarditis by affecting a valve-in-valve transcatheter aortic valve replacement that was successfully treated.

Electrocardiographic Recognition of Unprotected Left Main ST-Segment Elevation Myocardial Infarction: Looking Beyond aVR.

ST-segment elevation in aVR has traditionally been used for electrocardiographic identification of left main coronary artery (LM) myocardial infarction. We present two ST-segment elevation myocardial infarction (STEMI) cases with acute total occlusion of the LM without aVR ST-segment elevation. This report reviews the different electrocardiographic discriminators suggestive of unprotected LM STEMI.

An Uncommon Cause of ST-Segment Elevation Myocardial Infarction: Intramural Coronary Artery Hematoma After Blunt Chest Trauma.

Intramural coronary hematoma (IMCH) is a rare cause of acute myocardial infarction (MI). We aim to review the current knowledge and share our experience with the diagnosis and management of a patient presenting with traumatic IMCH leading to an acute ST-segment elevation MI. ().

Unmasking an acute coronary occlusive myocardial infarction in patients with right ventricular paced rhythm.

Electrocardiographic recognition of an acute myocardial infarction in the setting of a right ventricular paced rhythm (VPR) represents a unique diagnostic challenge. The classical ST-segment patterns of myocardial ischemia can become obscured by the abnormal repolarization changes caused by a right VPR. Consequently, longer door-to-balloon reperfusion times and a higher mortality have been reported among these patients mostly due to a delayed diagnosis.
