In this report, we describe the case of a 41‐year‐old man with hypertrophic cardiomyopathy presenting with right‐sided congestive heart failure symptoms. Noninvasive testing was suggestive, but non‐diagnostic for constrictive pericarditis (CP) and thus invasive hemodynamic catheterization was performed. The unique presence of both hypertrophic cardiomyopathy and constriction in this case led to lack of “modern” echocardiographic and invasive criteria for CP, based upon findings of enhanced ventricular dependence. However, classic hemodynamic criteria of early rapid filling with elevation and end‐equalization of diastolic pressures were present, and the patient ultimately received pericardiectomy with dramatic clinical improvement. © 2015 Wiley Periodicals, Inc.
Recurrent dyspnea following multiple ablations for atrial fibrillation explained by the “stiff left atrial syndrome”

We present the case of a patient who underwent repeated ablations for atrial fibrillation and presented with recurrent dyspnea, elevated left atrial pressure with large V waves in the absence of mitral regurgitation. This case provides an example of “stiff left atrial syndrome” as has been described in patients with mitral valve replacement and only recently in patients with radiofrequency ablations for atrial fibrillation. © 2012 Wiley Periodicals, Inc.
