A 50-year-old male patient who had undergone Senning repair for transposition of the great arteries at the age of 7 years was referred to our electrophysiology lab with recurrent supraventricular tachycardias. Fast anatomical mapping of the systemic venous atrium was performed with the CARTO electroanatomical mapping system. Propagation mapping with animated dynamic maps facilitates the understanding of the underlying mechanism and provides visualization of reentrant circuits of tachycardias in cardiac chambers with native barriers and surgical scars...

Orbital atherectomy has been developed as a method to modify calcified plaque in the peripheral vasculature, with extensive experience and data supporting its use in infrainguinal peripheral arterial disease. However, calcific atherosclerotic disease occurs in other vascular beds and may benefit from the application of this technology. In this case report, we describe the first reported use of orbital atherectomy in a renal artery. A 55-year-old male with severe drug-refractory hypertension was found to have renal artery stenosis, with severe calcification of the right renal artery...

A 76-year-old male presented with a submassive pulmonary embolism despite having an inferior vena cava (IVC) filter. Imaging demonstrated pulmonary artery emboli and a deep vein thrombosis in the left common femoral vein. Venography revealed the IVC filter with struts extending into the left and right renal veins. A new IVC filter was deployed below the prior filter. This case demonstrates IVC filter migration complicated by a submassive pulmonary embolism.

Paravalvular leak (PVL) following aortic valve implantation is a rare complication but may cause potentially serious consequences. It occurs in 2%-10% of surgical aortic valve replacements and 7%-17% of surgical mitral valve replacements. Transcatheter valve replacement data show that significant PVL occurs in 6%-8% of cases. The management of significant PVL has traditionally involved repeat surgical repair. However, many of these patients are considered too high risk to undergo a repeat surgical procedure; hence, a percutaneous transcatheter approach has often been utilized to treat these patients...

Severe tricuspid regurgitation is an independent predictor of adverse outcomes, yet few patients undergo surgery and treatment with medical therapy is often inadequate. Recent studies have reported the use of the MitraClip system (Abbott Vascular) to treat secondary tricuspid regurgitation. We describe the first use of MitraClip to treat severe primary tricuspid regurgitation and right heart failure in a patient with previous cardiac transplantation and high surgical risk.
