Tilt table transesophageal echocardiogram (inclination: 0º on left, 90º on right) with agitated saline revealing a postural-dependent increase in the right-to-left shunt. LA = left atrium, RA = right atrium.
Management of Platypnea-Orthodeoxia Syndrome by Transcatheter Closure of Atrial Communication: Hemodynamic Characteristics, Clin
Platypnea-orthodeoxia syndrome (POS) is defined as dyspnea and arterial desaturation induced by upright posture and relieved by recumbence.1,2 Although the precise underlying mechanism by which an atrial communication accounts for this disorder is un…
Transcatheter Management of Platypnea-Orthodeoxia Syndrome
Initially described in 1949 by Burchell et al.,1 the Platypnea-Orthodeoxia Syndrome (POS) is an uncommon symptom complex and was well characterized by the mid-1980s.2 POS is characterized by: 1) increased dyspnea in the upright position, relieved b…
The Treatment of Carotid Artery Bifurcation Stenoses with Systematic Stenting: Experience of First 100 Consecutive Cardiological
For many years the treatment of the stenosis of the carotid artery bifurcation has been the dominion of the vascular or neurosurgeon. Carotid endarterectomy has been shown to be beneficial with respect to the medical treatment for both symptomatic an…
Coronary Angioplasty Reduces Free Wall Rupture and Improves Mortality and Morbidity of Acute Myocardial Infarction
Free wall rupture (FWR) is one of the major causes of mortality of acute myocardial infarction (AMI).1–3 Acute free wall rupture leads to cardiac tamponade, rapid hemodynamic deterioration and almost instantaneous death. Previous studies demonstrated…
Reducing Myocardial Free Wall Rupture Following Acute
ST-Segment Elevation Myocardial Infarction: A Case for
Primary Angioplas
Myocardial free wall rupture (FWR) continues to be a dreadful complication of acute ST-segment elevation myocardial infarction (STEMI) occurring in about 1.3–2.5% of patients.1–3 FWR has been considered a significant cause of death in patients with S…
Patient satisfaction with same-day discharge PCI and arm complications.
Same-Day Discharge is Preferred by the Majority of the Patients Undergoing Radial PCI
Although diagnostic cardiac catheteriazation is usually performed on an out-patient basis, overnight stay is still the standard approach for the majority of patients undergoing percutaneous coronary intervention (PCI). The main reasons for this are t…
My Home is My Castle
Suppose you need coronary angioplasty. Would you prefer to stay in the hospital overnight or would you prefer to go home a few hours after your treatment? The answer will depend on the balance between the comfort of sleeping at home, on the one hand,…
Ascending Aortic Hemodynamics and One-Year Clinical Events
Following Percutaneous Coronary Intervention
Large vessel arterial compliance declines with advancing age and with atherosclerotic coronary artery disease.1-7 While compliance can be measured in a detailed manner using hi-fidelity hemodynamics,8 pulse pressure (aortic systolic pressure – aortic…
Intravascular Ultrasound Predictors of Subacute Vessel Closure after Balloon Angioplasty or Atherectomy
Vessel closure is a major complication after percutaneous coronary intervention (PCI) and is associated with a high rate of adverse clinical events.1,2 The occurrence of abrupt closure has been observed and evaluated mostly after stent implantation.3…
Changes in the minimal luminal diameter (MLD) before the procedure, immediately after the percutaneous coronary intervention (PCI), and at 24 hours.
Modifications of Minimal Luminal Diameter During the 24 Hours Following Percutaneous Treatment of In-Stent Restenosis
Luminal renarrowing after percutaneous coronary interventions (PCI) typically occurs several weeks after the procedure. The time course for modification of the luminal geometry after dilatation of in-stent restenosis (ISR) has been less characterized…
