A 71-year-old woman with a history of childhood pulmonary tuberculosis was admitted to our hospital for exertional dyspnoea (NYHA functional class II). Transthoracic and transoesophageal echocardiography demonstrated moderate to severe mixed mitral valve disease due to massive mitral annular calcification (MAC) and extensive infiltrative calcification of the atrioventricular groove. In addition, a very uncommon intramyocardial calcification of the ventricular septum and the lateral free wall was diagnosed. This case demonstrates a rare combination of mitral valve disease secondary to MAC, and a small hypertrophied left ventricle, as well as epipericardial and myocardial calcification likely due either to the massive MAC with myocardial extension or to former tuberculous perimyocarditis. The multidimensional imaging approach, which has been used in this particularly case, provided an excellent visualization and clinical evaluation of this rare finding. [ABSTRACT FROM PUBLISHER]

Background: There is increasing evidence that obstructive sleep apnea is an independent risk factor for arterial hypertension. Previous studies on the antihypertensive effects of positive airway pressure therapy on daytime blood pressure (BP) revealed inconsistent results. Methods: The relations between the apnea/hypopnea index (AHI) and BP or heart rate (HR) were investigated in a cohort of 540 consecutive patients (age, 55.4 ±11.1 years) with moderate or severe obstructive sleep apnea (OSA). The mean AHI was 28.2 ± 22.0 events/h before OSA therapy. A group of 196 patients in whom antihypertensive medication was kept unchanged was followed for 6 months during bilevel or continuous positive airway pressure (Bi-/CPAP) therapy. Results: Significant associations were found between AHI and systolic BP (β = 0.078, P = .014), diastolic BP (β = 0.056, P = .003), HR (β = 0.096, P < .001), and the prevalence of arterial hypertension (odds ratio = 0.015, P = .003), independent of age, body mass index, and gender. During the follow-up period with effective Bi-/CPAP therapy, the mean daytime systolic BP decreased from 130.7 ± 15.5 mm Hg to 128.6 ± 15.9 mm Hg (P = .051), diastolic BP from 80.2 ± 9.3 mm Hg to 77.5 ± 9.5 mm Hg (P = .001), and HR from 77.7 ± 8.8 to 75.7 ± 8.1 beats/min (P = .001). Multiple linear regression analysis revealed that the absence of antihypertensive drugs and the level of the initial BP are significant and independent predictors for the lowering effect of Bi-/CPAP therapy on systolic and diastolic BP. Conclusions: This study confirms an independent relationship between the severity of OSA and BP/HR. Absence of BP-lowering medication and BP values before treatment are independent predictors for the reduction of BP with Bi-/CPAP therapy. [Copyright &y& Elsevier]
