ABSTRACT
Here, we present a case of successful aortic valve repair of traumatic aortic regurgitation (AR). A man in his early twenties had a chest blunt trauma due to a bicycle accident 6 years earlier and suffered sternum fracture. He recovered without cardiovascular complications. Three months previously, a new diastolic murmur was detected on medical checkup. Transthoracic echocardiography (TTE) showed severe AR, and the left ventricular end-diastolic-/end-systolic dimension was 69/51 mm. Transesophageal echocardiography showed severe AR with perforation of the non-coronary cusp and dilatation of the aortic annulus (29.6 mm). Aortic valve repair was performed with an autologous pericardial patch and external suture annuloplasty. Postoperative TTE showed normal aortic valve function with trivial AR. He was discharged on postoperative day 11. Three months later, TTE showed trivial AR along with a reduced left ventricular dimension and improved left ventricular ejection fraction.
ABSTRACT
Perivalvular leakage (PVL) is one of the serious complications of mitral valve replacement. Between 1991 and 2006, 9 patients with mitral PVL underwent reoperation. All of them had severe hemolytic anemia before surgery. The serum lactate dehydrogenase (LDH) level decreased from 2,366±780 IU/<i>l</i> to 599±426 IU/<i>l</i> after surgery. The site of PVL was accurately defined in 7 patients by echocardiography. PVL occurred around the posterior annulus in 3 patients, anterior annulus in 2, anterolateral commissure in 1, and posteromedial commissure in 1. The most frequent cause of PVL was annular calcification in 5 patients. Infection was only noted in 1 patient. In 4 patients, the prosthesis was replaced, while the leak was repaired in 5 patients. There was one operative death, due to multiple organ failure, and 4 late deaths. The cause of late death was cerebral infarction in 1 patient, subarachnoid hemorrhage in 1, sudden death in 1, and congestive heart failure (due to persistent PVL) in 1. Reoperation for PVL due to extensive annular calcification is associated with a high mortality rate and high recurrence rate, making this procedure both challenging and frustrating for surgeons.
ABSTRACT
Coronary artery fistula is an unusual congenital anomaly, particularly in association with coronary aneurysm. In the present case, a right coronary fistula leading to the right atrium was associated with a giant coronary aneurysm. There have only been 3 such cases reported in the literature. Since both the aneurysm and the fistula were completely thrombosed, no heart murmur was detected and the patient was initially diagnosed as having an intracardiac tumor by echocardiography.
