Functional assessment of a left coronary-pulmonary artery fistula by coronary flow reserve
We report a 71-year-old man who presented with atypical chest pain. Coronary angiography did not reveal left main or proximal left anterior descending coronary artery stenosis, but a fistulous communication with a stronger tube-like fistula was present originating from the proximal left anterior descending coronary artery and emptying into the main pulmonary artery. Fractional flow reserve and coronary flow reserve measurements were performed to gain more data on the potential functional aspects of this fistula. With the present case, the importance of functional evaluation of these fistulas is demonstrated
Simultaneous Dual Distal Radial Balloon Aortic Valvuloplasty for Larger Aortic Annuli
Dual distal mini-balloon aortic valvuloplasty stabilized an 85-year-old patient with severe aortic stenosis. Puncturing both radial arteries solves the issue of large diameters at the aortic ring, introducing a feasible strategy in selected cases of fragile octogenarian patients with a high hemorrhagic risk. Moving at the anatomical snuffbox offers better postprocedural occlusion rates and better workspace ergonomics during the procedure
First application of the distal radial approach for severe mechanical surgical aortic valve paravalvular leak transcatheter closure with a double vascular plug : a case report
Severe aortic paravalvular leaks (PVLs) after surgical mechanical aortic valve replacement (AVR) represent a high risk for congestive heart failure, haemolysis, and infective endocarditis. This is the first reported case of distal radial artery (DRA) access for severe mechanical aortic PVL closure with a sequential double vascular plug guided by computed tomography angiography (CTA), transoesophageal echocardiography (TOE), and 3D TOE in an acute setting.A 51-year-old male presented with significant mixed aortic valve disease. Aortic valve replacement was performed (Slimline Bicarbon A-25 mm) according to guidelines. Four and 16 days later, a re-exploration was carried out due to pericardial effusion. Four months after discharge from rehabilitation, the patient was readmitted due to worsening dyspnoea on exertion and then at rest. Transthoracic echocardiography, TOE, and consequently, CTA, revealed severe PVL, following which the procedure of transcatheter PVL closure was chosen, with a preference for DRA access. After a CTA scan analysis and angiographic, TOE, and 3D TOE visualization of the leak, a 14/5 mm and a 10/5 mm vascular plug (AVPIII) were deployed to achieve good results. A 9-month clinical, echocardiographic, and CTA follow-up revealed good long-term results.For transcatheter PVL closure, CTA is helpful for not only vascular access planning, but also a visualization of the magnitude of the leak, location, and device planning. This case report demonstrates that the distal radial approach is feasible in patients with severe mechanical aortic valve PVL retrograde transcatheter closure. DRA access could possibly represent less bleeding and vascular access site complications when compared with femoral access and has some potential advantages over regular radial access
