In patients with exacerbation of severe CHF and functional MR, both modalities of non-invasive ventilation (CPAP and BiPAP) significantly improved ejection fraction and were equally effective in reducing MR.

In our patient, the double localization of the typical Brugada-pattern and the paradoxical effect of ajmaline on the ECG abnormalities confirmed the possibility of a phenotype heterogeneity in the Brugada syndrome.

Background Aorta–right atrial tunnel is a rare entity characterized by a iatrogenic vascular fistula, which connects aortic root and right atrium. It is frequently associated with congestive heart failure (HF). Case A 54 y female with an history of atrial septal defect (ASD) type ostium secundum closure and a recent mitral and tricuspid annuloplasty surgery, presents to the hospital with significant decrease in exercise tolerance and progressive shortness of breath. At the presentation, physical examination was significant for tachycardia, continuous murmur over precordium and lower extremity edema. ECG showed right ventricular pressure overload with repolarization abnormality. TTE showed moderate systolic flattening of the septum and dilated right sections. Non coronary cusp of aortic valve demonstrated a perforation extending to the right atrium (RA). ETE confirmed the connection between non–coronary aortic cusp and RA, furthermore revealed unkown sinus venosus type ASD. TC angiography showed a marked dilation of the pulmonary artery trunk (egg and banana sign) and a connection between aorta and RA. She was treated with surgical closure of aorta– right atrial tunnel and ASD through detached and pledget stitch closure. Follow–up reveals significant functional recovery of shortness of breath and exercise tolerance. Discussion Aorta– right atrial tunnel is a rare entity characterized by a vascular fistula, which connects one of the sinuses of Valsalva and the RA. It is a rare complication of tricuspid plastic surgery. It is classified according to its relation to the aorta to anterior or posterior. The clinical presentation ranges from asymptomatic continuous murmur to the symptoms of right sided HF. In our case, the presence of ASD accelereted and worsened the manifestations of right HF. It is usually diagnosed by TTE or ETE, TC angiography and aortography. The treatment of this condition is important even in asymptomatic cases due to the risk of aortic valve dysfunction, likely regurgitation, congestive right sided HF followed by left sided HF, calcification, infective endocarditis, aneurysmal dilatation and pulmonary hypertension. Conclusion The possibility of complications of aorta–right atrium fistula necessitates early therapy, even in asymptomatic patients or those with a hemodynamically insignificant shunt. Available treatment is surgical closure. It has a high mortality rate if it is not diagnosed adequately and surgically treated without delay.

Left atrial intramural hematoma (LAIH) is an uncommon entity for which a timely diagnosis is critical for decision making. Cardiac surgical or catheter-based procedures are potential causing factors. Though cardiac computerized tomography and magnetic resonance are highly accurate diagnostic modalities, their role is limited by the lack of widespread availability. The present clinical case illustrates the diagnostic features of LAIH that can be obtained using echocardiography at the bedside in critically ill patients. We report a case of LAIH, that followed a catheter ablation procedure and was complicated by cardiac and cerebral ischemia. Cardiac surgical management was required.
