RESUMO
The association of Standford type A acute aortic dissection with situs inversus totalis (SIT) is extremely rare and only a few cases are reported in the literature to date. Due to the particular rarity, this unusual condition, if not diagnosed quickly and correctly, can generate both clinical and surgical difficulties. Case presentation: We describe the case of a male Caucasian patient with SIT and aortic dissection type A, who occurred to our Emergency Department with a severe clinical condition of shock. Using the fast diagnostic approach with chest X-Ray and echocardiography followed by computed tomography investigation, a Standford type A acute aortic dissection and the presence of SIT were detected. The patient was subjected to surgical treatment with optimal results in a short time. Clinical discussion and conclusion: The event of aortic dissection is an extremely serious condition and the simultaneous presence of a critical clinical presentation with an unusual congenital anomaly could condition a correct and rapid diagnostic process. Only an accurate diagnostic investigation can give a quick diagnosis and useful elements for a correct therapeutic approach.
RESUMO
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.

BACKGROUND: Use of a minimally invasive approach for isolated aortic valve surgery is increasing. However, management of the root and/or ascending aorta through a mini-invasive incision is not so frequent. The aim of this study is to report our initial experience with surgery of the ascending aorta through a ministernotomy approach. METHODS: We retrospectively analyzed 102 patients treated for ascending aorta disease through a ministernotomy. Several types of surgeries were performed, including isolated or combined surgical procedures. Pre-operative and operative parameters and in-hospital clinical outcomes were retrospectively analyzed. RESULTS: Patient mean age was 63.9 ± 13.6 years (range 29-85). There were 33 (32.4%) female and 69 (67.6%) male patients. Preoperative logistic EuroSCORE I was 7.4% ± 2.1%. Mean cardiopulmonary bypass and aortic cross-clamp time were 123.7 ± 36.9 and 100.8 ± 27.5 min, respectively. In-hospital mortality was 0%. CONCLUSIONS: Our experience shows that surgery of the ascending aorta with or without combined procedures can be safely performed through an upper ministernotomy, without compromising surgical results. Although our series is not large, we believe that the experience gained on the isolated aortic valve through a ministernotomy can be safely reproduced in ascending aorta surgery as a routine practice.

BACKGROUND: To allow performance of "stand-alone" mitral annuloplasty with minimal invasiveness, percutaneous techniques consisting of delivery into the coronary sinus (CS) of devices intended to shrink the mitral valve annulus have recently been tested in animal models. These techniques exploit the anatomic proximity of the CS and mitral valve annulus in ovine or dogs. Knowledge of a detailed anatomic relationship between the CS, coronary arteries, and mitral valve annulus in humans is essential to define the safety and efficacy of percutaneous techniques in clinical practice. We sought to determine the qualitative and quantitative anatomic relationships between CS and surrounding structures in human hearts. METHODS AND RESULTS: The distance from the CS to the mitral valve annulus and the relationship between the CS and surrounding structures were studied in 61 excised cadaveric human hearts. Maximal distance from the CS to the mitral valve annulus was found to be up to 19 mm (mean, 9.7+/-3.2 mm). A diagonal or ramus branch, main circumflex artery, or its branches were located between anterior interventricular vein/CS and the mitral valve annulus in 16.4% and 63.9% of cases, respectively. CONCLUSIONS: Surgical anatomy suggests that in humans the CS is located behind the left atrial wall at a significant distance from the mitral valve annulus. Percutaneous mitral annuloplasty devices probably shrink the mitral valve annulus only by an indirect traction mediated by the left atrial wall; a theoretical risk of compressing coronary artery branches exists. Chronic studies are needed to address this problem and to determine long-term efficacy of such methods.
