Novel Use of Dual Guiding Catheters Technique to Prevent Distal Embolization and Slow Flow during PCI of Coronary Stent Thrombosis.

Despite having an incidence of 0.5 to 2%, stent thrombosis has an in-hospital mortality of 15% and myocardial infarction (MI) incidence of 67%. Even with the usage of thrombus aspiration devices and microvasculature vasodilators such as nitroprusside, verapamil, adenosine, and Gp2b/3a inhibitors, the angiographic result of percutaneous coronary intervention of coronary stent thrombosis remains frequently suboptimal due to distal embolization and subsequent slow flow.

Effect of Mitral Regurgitation on Systemic Coagulation Activity in Rheumatic Heart Disease as Assessed by D-dimer Levels.

Introduction Atrial fibrillation and mitral stenosis, especially in combination, increase the risk of left atrial thrombus formation and systemic embolization. However, whether severe mitral regurgitation (MR) improves systemic hypercoagulable state in these patients is unclear. remains unclear.

Transradial access for coronary diagnostic and interventional procedures: Consensus statement and recommendations for India: Advancing Complex CoronariES Sciences through TransRADIAL intervention in India - ACCESS RADIAL™: Clinical consensus recommendations in collaboration with Cardiological Society of India (CSI).

Radial access for cardiac catheterization and intervention in India has been growing steadily over the last decade with favorable clinical outcomes. However, its usage by interventional cardiologists varies greatly among Indian operators and hospitals due to large geographic disparities in health care delivery systems and practice patterns. It also remains unclear whether the advantages, as well as limitations of transradial (TR) intervention (as reported in the western literature), are applicable to developing countries like India or not.

Hepatic vein anchor-wire technique to prevent stent migration during inferior vena cava stenting for Budd-Chiari syndrome.

Inferior vena cava (IVC) stenting in patients suffering from Budd-Chiari syndrome (BCS) is sometimes complicated by stent migration or misplacement. Here, we describe a novel stent anchoring technique to prevent this complication while using balloon-mounted Palmaz stent for angioplasty of short-segment stenosis in the IVC.

Retrieving a deformed stent during transradial intervention: an alternative femoral approach using guide catheter shortening.

Stent dislodgment during percutaneous coronary intervention is a rare complication. We report a case of successful retrieval of a deformed coronary stent through alternative transfemoral approach while performing transradial procedure when the stent could not be retrieved safely from transradial route.

Transcatheter embolization of a giant pancreatic pseudoaneurysm: a tale of two bleeds and one thrombus!

Erosion of a peripancreatic artery into the pseudocyst as a result of enzymatic digestion of vessel wall gives rise to a pancreatic pseudoaneurysm (PSA), which is a rare complication seen in patients with chronic pancreatitis.(1) Angiographic embolization as a treatment method for acute hemorrhage from pancreatic PSA has become increasingly popular. Here we report a unique case with bleeding from a giant pancreatic PSA where the single PSA had blood supply originating from the branches of both the celiac artery and superior mesenteric artery.

Bedside percutaneous transseptal mitral commissurotomy under sole transthoracic echocardiographic guidance in a critically ill patient.

Percutaneous transvenous mitral commissurotomy is an effective and safe alternative to surgical treatment, in selected patients of rheumatic mitral stenosis. It is usually performed under fluoroscopic guidance in the catheterization laboratory. We report the successful performance of emergency mitral commissurotomy by the Inoue balloon at bedside under sole transthoracic echocardiographic guidance in a critically ill patient.

Successful closure of coronary artery perforation using non-conventional embolic material.

Coronary perforation during percutaneous coronary interventions is a rare but dreadful complication. While coronary perforation involving large vessels are managed successfully by covered stents, small distal vessel perforation is usually managed by prolonged balloon inflation or embolization of gel foam/thrombogenic metallic coils. We describe a case, where perforation of a small ventricular branch of the right coronary artery was successfully occluded by packing it with pieces of thrombogenic floppy tips of used coronary angioplasty guidewires instead of conventional metallic coils.

Effects of percutaneous mitral commissurotomy on longitudinal left ventricular dynamics in mitral stenosis: quantitative assessment by tissue velocity imaging.

Objective: We hypothesized that mitral annular velocities would improve immediately after relief of mitral stenosis and that serial assessment could be used as an index for quantifying functional changes after percutaneous mitral commissurotomy (PMC).

Methods: Longitudinal left ventricular annular velocities were quantified by spectral pulsed wave Doppler tissue velocity imaging in 25 patients (16 women; mean age [+/-SD], 29.2 +/- 8.

Regional dyssynergy of the interventricular septum after septal artery occlusion in hypertrophic obstructive cardiomyopathy: use of quantitative Doppler tissue and strain rate imaging.

We report the regional myocardial mechanics of the interventricular septum in a patient with hypertrophic obstructive cardiomyopathy undergoing therapeutic septal artery occlusion. Myocardial velocities improved across the entire septum; however, strain rate imaging showed the presence of severe regional dyssynergy.

Percutaneous closure of coronary pulmonary arterial fistula using catheterization laboratory trash.

We report a case of coronary pulmonary arterial fistula that was successfully occluded by packing the fistula with thrombogenic floppy tips of used percutaneous transluminal coronary angioplasty guidewires instead of conventional steel coils.

Successful transcatheter closure of ruptured sinus of Valsalva aneurysm.

We report a case in which a ruptured aneurysm of the sinus of Valsalva opening into the right atrium was successfully closed transcutaneously by an Amplatzer duct occluder.

Successful closure of iatrogenic femoral artery pseudoaneurysm: a new minimally invasive technique.

Pseudoaneurysm following diagnostic or interventional procedures is a well-known complication. We describe a new method of closing a femoral pseudoaneurysm in a case where ultrasound-guided compression had failed. Instead of packing the sac permanently with coils, thrombus formation was successfully induced by temporary placement of a coil transcutaneously in the psendoaneurysm sac, which resulted in closure of the pseudoaneurysm.
