Multiple and aggressive pulmonary vein transcatheter interventions as bridge to transplantation in primary diffuse pulmonary vein stenosis.
Primary diffuse congenital pulmonary vein stenosis (PDPVS) is a severe condition with poor prognosis. No therapeutic strategy has been found to be effective in its management to date. We report the case of a premature child with severe PDPVS who underwent multiple transcatheter interventions as bridge to heart-lung transplantation.

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 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.

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 StudyA comparison of transcatheter aortic valve implantation and surgical aortic valve replacement in 1,141 patients with severe symptomatic aortic stenosis and less than high risk.
To assess outcomes for patients undergoing transcatheter aortic valve implantation (TAVI) versus surgical aortic valve replacement but with less than high risk. ⋯ In this large, single center, real world dataset there was no difference in mortality between patients undergoing TAVI or SAVR during a 3-year follow-up but there was a TAVI related increase in major vascular complications, new pacemaker implantation and aortic insufficiency and a SAVR related increased bleeding risk.
