A 76-year-old man diagnosed with severe pure native aortic regurgitation (PNAR) underwent transcatheter aortic valve replacement (TAVR) due to high surgical risk. The computed tomography angiography showed no calcification and no stenosis of the aortic valve, with an annulus perimeter of 81.1 mm and sinus diameters of 35 to 38 mm.
Quantification of invasive hemodynamics and mitral annular calcification-related mitral stenosis remains underexplored in patients exposed to chest radiation. We sought to explore invasive hemodynamic parameters via transseptal catheterization in patients with and without chest radiation who had a diagnosis of mitral annular calcification-related mitral stenosis. After excluding patients with more than moderate mitral regurgitation, we found that there was no difference in mitral valve area on hemodynamic testing in patients with and without radiation with an elevated baseline transmitral gradient on transthoracic echocardiography in the setting of mitral annular calcification-related mitral stenosis. There was a higher transmitral gradient and left atrial pressure in patients with prior radiation consistent with left atrial noncompliance, suggesting that treatment mitral valve stenosis may not relieve symptoms in this cohort of patients.
A 59-year-old diabetic man with a history of numerous coronary angiographies (CAs) and peripheral artery disease underwent CA due to a non-ST elevation myocardial infarction. Femoral, radial, and ulnar arteries were unpalpable.
A 63-year-old man presented with delayed inferior ST-elevation myocardial infarction complicated with ventricular septal rupture (VSR). He developed cardiogenic shock and respiratory failure requiring intubation and Impella (Abiomed) support.
