OBJECTIVES: We designed a pilot study to evaluate safety and feasibility of an inexpensive and simple approach to intracoronary hemodilution during primary angioplasty (PPCI) to reduce reperfusion injury. INTRODUCTION: Early revascularization in acute myocardial infarction decreases infarct size and improves outcomes. However, abrupt restoration of coronary flow results in myocardial reperfusion injury and increased final infarct size. Dilution of coronary blood during revascularization may help reduce this damage...

The use of atrial septal device occluders can lead to device embolization. This major complication can occur due to loose margins, deficient aorta, or thin and floppy posterior rim. Device embolization most often occurs after device release, and retrieval is essential. Many devices, including snare and bioptome, have been utilized for retrieval. However, performing these procedures can be difficult and time consuming. Failure to retrieve the embolized device requires open heart surgery. We report a novel and easy to perform method, "coronary wire trap technique," in the event of retrieval failure using conventionally available devices and snare, thereby preventing open-heart surgery...

PATIENT PRESENTATION: We report the case of a 66 year old female who presented to our institution fourteen years after receiving a St. Jude Mechanical Mitral Valve Replacement. She presented in refractory NYHA class IV congestive heart failure with comorbidities of acute renal failure, liver failure, and mental status changes. She was found to have immobility of one of the mitral valve disks with resultant severe mitral stenosis with a mean pressure gradient of 12 mmHg. EVALUATION AND MANAGEMENT: The patient was found to have an STS predicted mortality of 39% with redo surgical MVR, and evaluation by the valve team led to a recommendation of a hybrid surgical and transcatheter procedure...

The phenomenon of coronary steal is well known in the setting of HLHS (Hypoplastic Left Heart Syndrome) early after the Classical Norwood Operation. We report a rare case of an infant with HLHS [Severe Aortic Stenosis (AS), Mitral Stenosis (MS) and small Left Ventricle (LV)], who developed aortic regurgitation and presumed coronary steal late after the Sano Modification of the Norwood Procedure. Coronary steal developed secondary to progressive aortic and mitral regurgitation and resulted in poor right ventricular function and severe tricuspid regurgitation...

BACKGROUND: The age-dependent outcome of carotid artery stenting (CAS) outside of randomized controlled trials is largely unknown. Therefore, we assessed acute and long-term results of CAS in a single-center real-world registry. METHODS: All symptomatic and asymptomatic patients who consecutively underwent CAS were enrolled into the present analysis. The population was divided into three groups dependent on patients' age (<65, 65-74, and ≥75 years). RESULTS: Between 1999 and 2015, a total of 878 patients (24%, <65 years; 40%, 65-74 years; and 36%, ≥75 years) underwent CAS...

Transcatheter mitral valve replacement has been successfully performed with the use of aortic transcatheter heart valves in hundreds of patients worldwide with severe dysfunction of a degenerated mitral bioprosthesis and high surgical risk for repeat operation. The delivery approach in the vast majority of the mitral valve-in-valve procedures has been transapical. Although the transseptal approach may be more technically challenging, it is less invasive and may be preferred by patients. Data from case series and a large international registry suggest that patients treated with transseptal mitral valve-in-valve have faster recovery, more improvement in left ventricular ejection fraction and possibly lower mortality compared with patients treated with transapical approach...

Here, we report a four-day old neonate presenting with cardiovascular collapse secondary to a descending aorta to right atrial fistula. Echocardiography was suggestive of the diagnosis and confirmed with computed tomographic (CT) imaging. The fistula was successfully occluded via cardiac catheterization using an Amplatzer Vascular Plug II implanted from the right atrial aspect. This report includes the first CT imaging of this extremely rare congenital defect as well as detailing the first successful transcatheter occlusion of this particular lesion...

BACKGROUND: Amphilimus sirolimus-eluting stents (A-SES) represent a novel elution technology in the current era of drug-eluting stents with promising results in patients with diabetes mellitus. At present no large trial has been designed to evaluate clinical outcomes of A-SES as compared to new-generation drug-eluting stents in unselected patients. Accordingly, we designed this trial to evaluate clinical noninferiority of A-SES as compared with zotarolimus-eluting stents (ZES) in a real-world, all-comers setting...
