Multicenter Study Observational StudyUse and outcome of radial versus femoral approach for primary PCI in patients with acute ST elevation myocardial infarction without cardiogenic shock: results from the ALKK PCI registry.
This study sought to compare the use and outcome of radial versus femoral access in patients treated with primary percutaneous coronary intervention (PCI) for acute ST elevation myocardial infarction (STEMI) in clinical practice. ⋯ The radial approach for PCI can be performed with excellent procedural success in selected STEMI patients and is associated with a lower rate of vascular access complications and hospital mortality.

Multicenter StudyRisk and outcomes of complications during and after MitraClip implantation: Experience in 828 patients from the German TRAnscatheter mitral valve interventions (TRAMI) registry.
To analyze risk and outcomes of complications during and after MitraClip implantation using multicenter data from the prospective German Transcatheter Mitral Valve Interventions (TRAMI) registry. ⋯ MitraClip implantation appears to be a safe treatment option with low rates of MACCE and clip-specific complications. Nevertheless, MitraClip therapy is not without complications. Careful patient selection and improvements in preventing peri-procedural bleeding have the potential of reducing post-procedural complications and improving outcomes.

Clinical TrialPrimary percutaneous coronary intervention by drug-eluting balloon angioplasty: the nonrandomized fourth arm of the DEB-AMI (drug-eluting balloon in ST-segment elevation myocardial infarction) trial.
To evaluate a paclitaxel drug-eluting balloon (DEB) only strategy in primary percutaneous coronary intervention (PPCI), aiming at a comparison with bare metal stent (BMS) alone, DEB followed by BMS, and paclitaxel eluting stent (PES), as assessed in the randomized Drug Eluting Balloon in Acute ST-Segment Elevation Myocardial Infarction (DEB-AMI) trial. ⋯ PPCI by DEB-only in selected patients yielded an angiographic outcome comparable to BMS alone and DEB followed by BMS. PES proved angiographic superiority to DEB-only. DEB-only is therefore a potential treatment alternative during PPCI in patients with contra-indications to drug-eluting stents.

Comparative StudyTranscatheter balloon dilation for recurrent right ventricular outflow tract obstruction following valve-sparing repair of tetralogy of Fallot.
Valve-sparing repair in patients with tetralogy of Fallot (TOF) carries the risk of residual or recurrent right ventricular outflow tract (RVOT) obstruction, which is often treated with transcatheter balloon dilation (BD). The outcomes and associated complications of BD of the RVOT in this scenario remain unknown. ⋯ BD in patients with recurrent RVOT obstruction following valve-sparing repair of TOF acutely reduces the RVOT gradient, but commonly results in increased PR and is associated with a high reintervention rate. Patients with stenosis solely at the level of the valve had a better response to this type of intervention.

Comparative StudyThe effect of patent foramen ovale closure in patients with platypnea-orthodeoxia syndrome.
Platypnea-orthodeoxia syndrome is a rare condition characterized by hypoxemia in the upright position that is improved in the supine position. Although several etiologies of platypnea-orthodeoxia exist, it is frequently associated with right-to-left shunting of blood at the cardiac or pulmonary level, usually via a patent foramen ovale (PFO). The aim of this study was to evaluate the incidence of platypnea-orthodeoxia syndrome in a select patient population with right-to-left shunting and to describe the outcomes after PFO closure. ⋯ PFO closure may resolve symptomatic postural dyspnea and hypoxemia and is an effective method for treating platypnea-orthodeoxia, but is not effective when the primary etiology of the hypoxemia is due to a pulmonary cause.
