[Ab] Abstract:Auscultation of heart dispenses identification of the cardiac valves. An electronic stethoscope is used for the acquisition of heart murmurs that is further classified into normal or abnormal murmurs. The process of heart sound segmentation involves discrete wavelet transform to obtain individual components of the heart signal and its separation into systole and diastole intervals. This research presents a novel scheme to develop a semi-automatic cardiac valve disorder diagnosis system. Accordingly, features are extracted using wavelet transform and spectral analysis of input signals. The proposed classification scheme is the fusion of adaptive-neuro fuzzy inference system (ANFIS) and HMM. Both classifiers are trained using the extracted features to correctly identify normal and abnormal heart murmurs. Experimental results thus achieved exhibit that proposed system furnishes promising classification accuracy with excellent specificity and sensitivity. However, the proposed system has fewer classification errors, fewer computations, and lower dimensional feature set to build an intelligent system for detection and classification of heart murmurs.

[Ab] Abstract:Blunt chest trauma can cause not only damage to the thoracic cage, but can also injure intracardiac structures including the papillary muscles, chordae tendineae, and valve leaflets. Aortic valve (AV) injury secondary to blunt chest trauma is a rare occurrence. Clinically, AV injury may be missed during the initial post-trauma assessment due to the lack of suspicion of cardiac involvement. Thus, the diagnosis of AV injury is often delayed or missed for a time interval of days to months. As a consequence, the traumatic AV regurgitation can rapidly or progressively lead to congestive heart failure unless surgically corrected. Therefore, emergency physicians should be aware of the possibility of intracardiac structure injury, such as valvular injuries, after blunt chest trauma. Guidelines for the appropriate use of bedside cardiac ultrasound (BCU) recommend BCU should be performed in all patients with new murmurs for clinically significant valvular lesions that could potentially change management. We described the case of a 73-year-old female patient with AV injury after blunt trauma. She experienced cardiac arrest (CA) secondary to a moderate-to-severe traumatic AR, which was successfully treated with emergency AV replacement. We discuss how to diagnose and manage a CA patient, aided by BCU, with ventricular failure associated with persistent AV regurgitation. To the best of our knowledge, this is the first case report on CA associated with isolated rupture of bicuspid AV rupture and AV regurgitation secondary to blunt chest trauma because of the lack of early suspicion of AV injury.

[Ab] Abstract:This article outlines the diagnosis and management of commonly occurring valvular heart diseases for the primary care provider. Basic understanding of pathologic murmurs is important for appropriate referral. Echocardiography is the gold standard for diagnosis and severity grading. Patients with progressive valvular heart disease should be followed annually by cardiology and imaging should be performed based on the severity of valvular dysfunction. Surgery or intervention is recommended only when symptoms dictate or when changes in left ventricular function occur. Surgery or intervention should be performed after discussion by a heart team, including cardiologists and cardiac surgeons.

[Ab] Abstract:A 25-year-old man, who was an active duty US Navy sailor, went to his ship's medical department complaining of a mild cough that he'd had for 2 days. He denied having any fevers, chills, night sweats, angina, or dyspnea. He said he hadn't experienced any exertional fatigue or difficulty completing the rigorous physical tasks of his occupation as an engineman on the ship. The patient had no medical or surgical history of significance, and he wasn't taking any medications or supplements. On exam, he was not in acute distress and his vital signs were within normal limits. Auscultation revealed mild wheezing throughout the upper lung fields and loud heart sounds throughout his chest that were audible even with gentle contact of the stethoscope diaphragm. He had no discernible murmurs, rubs, or gallops. In light of the unusually loud heart sounds heard on exam, we performed an electrocardiogram. The EKG revealed a normal sinus rhythm, slight right axis deviation indicated by tall R-waves in V1 (also suggestive of right ventricular hypertrophy), an incomplete right bundle branch block, and a crochetage sign (a notch in the R-waves of the inferior leads). A chest x-ray revealed a normal-sized heart and dilated pulmonary vasculature suggestive of pulmonary hypertension.

[Ab] Abstract:Commonly reported complications of hepatic cysts are spontaneous hemorrhage, rupture into the peritoneal cavity, infection and compression of the biliary tree however cardiac complications are not commonly reported. We are presenting a case of a large liver cyst presenting with right atrial and ventricular inflow tract impingement resulting in cardiac symptoms. A 68 year-old Hispanic female presented with one month of fatigue and shortness of breath after household work and walking less than one block, right upper quadrant pain and weight loss. She had history of multiple hepatic cysts for more than 12 years, well-controlled diabetes and hypertension. Examination of the heart revealed tachycardia with regular heart sounds. There were no murmurs. She had tenderness in her right upper quadrant on palpation and an enlarged smooth liver. Rest of physical examination was unremarkable. CT scan of the abdomen showed multiple non-enhancing liver cysts in both lobes, with the largest measuring 12 x 15 x 17 cm which was significantly increased from her baseline of 7 x 8 x 10 cm in 2003. Echocardiogram showed normal left ventricular ejection fraction, grade 1 diastolic dysfunction and a hepatic cyst impinging RA and RV inflow tract. She had successful laparoscopic enucleation of liver cyst and subsequent relief from tachycardia, fatigue and shortness of breath. In conclusion, this case illustrates that hepatic cysts may become symptomatic after remaining quiescent for an extended period. They may present with unusual symptoms and clinicians should be mindful of rare complications, such as in this case.

[Ab] Abstract:Critical coarctation of the aorta in neonates is a common cause of shock and death. It may be the most difficult of all forms of critical congenital heart disease to diagnose because the obstruction from the coarctation does not appear until several days after birth (and after discharge from the hospital), and because there are no characteristic murmurs. Some of these patients may be detected by neonatal screening by pulse oximetry, but only a minority is so diagnosed. Older patients are usually asymptomatic but, although clinical diagnosis is easy, they are frequently undiagnosed.

[Ab] Abstract:Sinus of Valsalva aneurysms are extremely rare, and usually of a congenital nature. There are few documented cases of this condition during pregnancy, which renders unclear the therapeutic options. We here report the case of a 26 years old pregnant woman who was referred to our cardiac center for the evaluation of a heart murmur. The two-dimensional transthoracic echocardiography allowed quickly to establishthe diagnosis of a ruptured sinus of Valsalva aneurysm into the right ventricle. A successful surgical correction of the ruptured aneurysm was performed with patch repair.

[Ab] Abstract:The incidence of blunt chest trauma (BCT) is greater than 15% of all trauma admissions to the emergency departments worldwide and is the second leading cause of death after head injury in motor vehicle accidents. The mortality due to BCT is inhomogeneously described ranging from 9% to 60%. BCT is commonly caused by a sudden high-speed deceleration trauma to the anterior chest, leading to a compression of the thorax. All thoracic structures might be injured as a result of the trauma. Complex cardiac arrhythmia, heart murmurs, hypotension, angina-like chest pain, respiratory insufficiency or distention of the jugular veins may indicate potential cardiac injury. However, on admission to emergency departments symptoms might be missing or may not be clearly associated with the injury. Accurate diagnostics and early management in order to prevent serious complications and death are essential for patients suffering a BCT. Optimal initial diagnostics includes echocardiography or CT, Holter-monitor recordings, serial 12-lead electrocardiography and measurements of cardiac enzymes. Immediate diagnostics leading to the appropriate therapy is essential for saving a patient's life. The key aspect of the entire management, including diagnostics and treatment of patients with BCT, remains an interdisciplinary team involving cardiologists, cardiothoracic surgeons, imaging radiologists and trauma specialists working in tandem.

[Ab] Abstract:Death risk factors of patients with antineutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV) were explored by the analysis of clinical characteristics of AAV patients, as to provide the basis for early diagnosis and treatment, and reduction of mortality and also improvement of prognosis. A retrospective study was conducted in patients with AAV which were admitted to this hospital from November 2003 to February 2017, by the contrasts of the similarities and differences of clinical characteristics between the death group and non-death group, for explore the risk factors of death. (1) A total of 66 patients with AAV were included in this study, in which 20 were died (male/female was 12/8), and 46 were still alive, with a total mortality rate of 30.3%.(2)The average age of disease onset in the death group was (67±13) years, which was significantly higher than that of the control group (55±18, =0.009). (3)The mean value of vasculitis damage index (VDI) in the death group was (6.4±2.5), which was significantly higher than that in the non-death group (4.4±2.5, =0.006). (4)As to multiple organs involvements among the heart, lung, kidney, gastrointestinal tract, central nervous system and other organs, the proportion of three or more organs involvement in the death group was 85% (17/20), which was significantly higher than that in the control group 47.8%(22/46), =0.004 8.The incidence of heart murmurs, recent premature beats, aortic insufficiency, chronic heart failure/cardiomyopathy, and massive hemoptysis were significantly higher than those in the control group ( <0.05). (5) The incidence of infection in the death group (55%) was significantly higher than that in the control group (28.3%, =0.038). An onset age of more than 65, multiple organs involvement, especially the occurrence of massive hemoptysis, heart valve diseases, heart failure and other cardiovascular involvements, increased VDI and combination of infections are the risk factors of death in AAV patients.
