Balloon Lithoplasty for Preparation of Severely Calcified Coronary Lesions
Severely calcified coronary stenoses are difficult to treat with percutaneous coronary intervention (PCI) using current techniques and there is little specific evidence on how to best treat these cases. It is hypothesized that balloon lithoplasty is superior to conventional balloons for lesion preparation of severely calcified coronary lesions before stent …

Cryoballoon Pulmonary Vein Isolation for Atrial Fibrillation With Heart Failure
The combination of atrial fibrillation (AF) and heart failure (HF) is common and implies a poor prognosis. Pulmonary vein isolation is an established method for the treatment of symptomatic AF in patients with normal heart function and has been shown to be more effective than drug therapy. Recently, radiofrequency ablation …

Assessment of Paravalvular Leak After TAVI by Hemodynamic Measurements and Cardiac MRI
Rationale: Transcatheter aortic valve implantation (TAVI) has become the standard therapy for elderly patients with high surgical risks. Paravalvular leakage after TAVI is relatively common and there is conflicting evidence regarding the clinical impact of mild paravalvular leakage in self-expanding devices. Prospective data for self-expanding devices are required to compare …
