Iatrogenic aortic dissection is an infrequent complication of cardiac catheterization (0.03-0.06%) associated with up to 19% of mortality at 30 days. It was reported to mostly occur when using a 6-Fr guiding catheter to cannulate the right coronary artery. This life-threatening complication usually requires early surgical management and close imaging monitoring and control of systolic blood pressure. This case report describes a patient with iatrogenic aortic dissection during cardiac catheterization in symptomatic coronary artery disease...

Isolated coronary artery bypass grafting associated with atrial fibrillation is routinely performed through a sternotomy, and cardiac arrest. Advancements in this surgical approach have led to better cosmesis, a quick postoperative recovery, with the same postoperative results. We report a case of a novel, less invasive hybrid treatment combining robot-assisted coronary artery bypass grafting and percutaneous radiofrequency catheter ablation.

Smartphones and electronic tablets (e-tablets) have become ubiquitous devices. Their ease of use, smartness, accessibility, mobility and connectivity create unique opportunities to improve quality of surgical care from prehabilitation to rehabilitation. Before surgery, digital applications (Apps), serious games and text messaging may help for a better control of risk factors (hypertension, overweight), for smoking cessation, and for optimizing adherence to preoperative recommendations (e.g., regarding anticoagulation or antihypertensive treatments)...

The stabilization of a guiding catheter is a very important factor for successful endovascular treatment. However, it is sometimes difficult to obtain sufficient stabilization because of the tortuosity of the approach route. A Goose Neck Snare is useful for the retrieval of intravascular foreign bodies and can be used to hold the guiding catheter. We describe five cases of endovascular treatment performed while using the Goose Neck Snare via the brachial artery to hold the guiding catheter. We discuss the utility of this strategy...

We sought to compare pulmonary flow hemodynamic indices obtained by Fick and thermodilution catheterization techniques with phase-contrast MRI (PC-MRI) in children with diverse etiologies of pulmonary arterial hypertension (PAH). Calculation of pulmonary flow ([Formula: see text]) using the Fick principle in most catheter laboratories relies on an estimate of oxygen consumption which may limit its reliability. Flow hemodynamic indices acquired from thirty patients with PAH who underwent successful same-day PC-MRI and catheterization were evaluated for absolute and percent bias...

PURPOSE: To describe the use of a re-entry catheter in the endovascular treatment of left subclavian stenosis. MATERIALS AND METHODS: We present three patients where initial attempts at re-vascularisation using standard techniques were unsuccessful. An OUTBACK catheter was employed to facilitate re-entry in these patients. RESULTS: True lumen re-entry was achieved in all patients, leading to successful treatment of all stenoses. There was a lack of filling of the left vertebral artery post-angioplasty in one patient; this was not clinically significant...

The FloTrac system is a system for cardiac output (CO) measurement that is less invasive than the pulmonary artery catheter (PAC). The purposes of this study were to (1) compare the level of agreement and trending abilities of CO values measured using the fourth version of the FloTrac system (CCO-FloTrac) and PAC-originated continuous thermodilution (CCO-PAC) and (2) analyze the inadequate CO-discriminating ability of the FloTrac system before and after cardiopulmonary bypass (CPB). Fifty patients were included...

We herein present a case of distal aortic arch aneurysm with an isolated left vertebral artery(LVA). In surgery, after establishing cardiopulmonary bypass, the LVA was anastomosed to the left common carotid artery (LCCA) while under moderate hypothermia. Selective cerebral perfusion (SCP) was then initiated by inserting catheters into the brachiocephalic artery( BCA), the LCCA and the left subclavian artery (LSA). The aorta was transected between the BCA and the LCCA, and an open stent graft was deployed into the descending aorta during circulatory arrest...

A 53-year-old woman was referred to us for reoperation of aortic root. Twenty-three years ago, she was diagnosed with aortitis and suffered from annuloaortic ectasia, aortic regurgitation, severe stenosis of left carotid and subclavian arteries and occulusion of the main trunk of left coronary artery. The left coronary system was perfused by collateral arteries from right coronary artery. She had undergone original Bentall procedure( Cooley graft 26 mm+SJM valve 25 mm) with coronary artery bypass grafting (CABG)[saphenous vein graft (SVG)-left anterior descending artery (LAD)]...

REVIEW
Ikuo Fukuda, Kazuyuki Daitoku
Acute pulmonary thromboembolism is a catastrophic event, especially for hospitalized patients. The prognosis of pulmonary thromboembolism depends on the degree of pulmonary arterial occlusion. The mortality of massive pulmonary embolism is reportedly as high as 25% without cardiopulmonary arrest and 65% with cardiopulmonary arrest. In patients with unstable hemodynamics due to pulmonary thromboembolism, surgical pulmonary embolectomy is indicated for patients with a contraindication to thrombolysis, failed catheter therapy, or failed thrombolysis...

We present the case of an 81-year-old female with flush occlusion of the superficial femoral artery (SFA) and percutaneous transluminal angioplasty. Initially, the antegrade approach failed due to flush occlusion without stump. Hard, round surfaced, calcific, and eccentric plaque of the ostium of SFA was also present, which involved distal common femoral artery (CFA). Thus, we successfully used a Frontrunner catheter for retrograde reentry at the lower position of the CFA. Various treatment strategies involving Frontrunner and atherectomy devices could make percutaneous procedures possible in femoropopliteal occlusive disease, involving the CFA...

Objectives: Although venography guidance is helpful for central venous catheter placement, it is sometimes difficult to place a peripheral intravenous cannula for enhancement. We designed a new technique for establishing femoral venous access using venography guidance in the return phase of peripheral arteriography. This new technique was named arterial injection venous return guidance. Here we assessed the efficacy and safety of arterial injection venous return guidance. Methods: We reviewed data of 29 infants less than 6 months old undergoing catheter intervention at our institute in 2014...

OBJECTIVE: Acute lung injury (ALI) is one of the most common extra-pancreatic complications of acute pancreatitis. In this study, we examined the protective effect of protease inhibitor aprotinin and a matrix metalloproteinase inhibitor (MMPi) on pulmonary inflammation in rats with severe pancreatitis-associated ALI. METHOD: A rat model of acute pancreatitis (AP) was established by injecting sodium glycodeoxycholate (GDOC) into the pancreatic duct. Pharmacological interventions included pretreatment with a protease inhibitor aprotinin (10mg/kg) and a matrix metalloproteinase inhibitor (MMPi, 100g/kg)...
