- Fertile eunuch syndrome in association with biventricular noncompaction, bicuspid aortic valve, severe aortic stenosis, and talipes equinovarus. [Journal Article]
- Tex Heart Inst J 2013; 40(2):204-6.
Noncompaction of the ventricular myocardium is a congenital cardiomyopathy characterized by prominent ventricular trabeculations and deep intertrabecular recesses. In most cases, noncompaction is an isolated disease confined to the left ventricular myocardium. Fertile eunuch syndrome is a hypogonadotropic hormonal disorder in which the levels of testosterone and follicle-stimulating hormone are low. We report a case of biventricular noncompaction in association with bicuspid aortic valve and severe aortic stenosis in a 42-year-old man who was diagnosed with talipes equinovarus and fertile eunuch syndrome during childhood.
- Perioperative management of a levoatrial cardinal vein in the absence of the brachiocephalic vein. [Journal Article]
- Tex Heart Inst J 2013; 40(2):201-3.
Levoatrial cardinal vein is a rare congenital anomaly of the systemic veins. It is commonly associated with left-sided obstructive conditions such as aortic atresia, mitral atresia, and cor triatriatum. We report the case of a 14-year-old boy who was undergoing surgery for correction of a secundum atrial septal defect. Intraoperatively, we discovered that he had a levoatrial cardinal vein and no brachiocephalic vein. However, collateral vessels provided adequate flow to the right atrium, and the patient's left-sided venous pressure was not excessive, so we ligated the levoatrial cardinal vein and directly repaired the septal defect. Postoperatively, the left venous drainage was satisfactory and the patient was asymptomatic. In addition to our patient's case, we discuss the embryology, diagnosis, and treatment of levoatrial cardinal vein.
- Single-Stage Repair of Aortic Coarctation and Multiple Concomitant Cardiac Lesions through a Median Sternotomy. [Journal Article]
- Tex Heart Inst J 2013; 40(2):198-200.
Through a median sternotomy, we performed a single-stage repair of severe aortic coarctation, ventricular septal defect, patent foramen ovale, and mitral valve insufficiency. The severe aortic coarctation was repaired by interposing a synthetic graft between the distal ascending aorta and the descending aorta. We first repaired the coarctation with the 38-year-old man on cardiopulmonary bypass, before aortic cross-clamping, in order to shorten the cross-clamp time.
- Transcatheter aortic valve replacement in a nonagenarian. [Journal Article]
- Tex Heart Inst J 2013; 40(2):196-7.
Approximately 30% to 40% of elderly patients with severe, symptomatic aortic valve stenosis are deemed ineligible for surgery because of high perioperative risk. We describe the use of an alternative transfemoral approach known as transcatheter aortic valve implantation in a nonagenarian patient with severe aortic stenosis. Our patient recovered successfully, and by the time of her most recent follow-up visit, 7 months after the procedure, she had regained a substantial degree of function. This result suggests that transcatheter aortic valve implantation can enable some high-risk patients who are ineligible for surgery to undergo valve replacement, thereby regaining both quality and length of life.
- Cardiac Amyloidosis Presenting with Prolonged QT Interval and Recurrent Polymorphic Ventricular Tachycardia. [Journal Article]
- Tex Heart Inst J 2013; 40(2):193-5.
Cardiac amyloidosis results in severely symptomatic heart failure that has a poor prognosis because of the development of a restrictive cardiomyopathy. The diagnosis of cardiac amyloidosis is often delayed because of nonspecific signs and symptoms. We report the case of a 66-year-old woman who had been diagnosed with sick sinus syndrome and presented 5 months later with a long QT interval and recurrent polymorphic ventricular tachycardia. The diagnosis of cardiac amyloidosis was confirmed upon analysis of endomyocardial biopsy results. The patient was subsequently diagnosed with and treated for underlying plasma cell myeloma and later died of cardiac arrest. This atypical presentation of cardiac amyloidosis underscores the need to consider it in the differential diagnosis of patients who have ventricular arrhythmias. To our knowledge, the combination of long QT interval and polymorphic ventricular tachycardia has not been previously reported in association with amyloid heart disease.
- Mediastinal Paraganglioma between the Great Vessels in an 81-Year-Old Woman. [Journal Article]
- Tex Heart Inst J 2013; 40(2):189-92.
Nonfunctional paragangliomas are slow-growing, typically benign tumors that arise from the extra-adrenal paraganglion of the autonomic nervous system. They are identified and characterized with the use of computed tomography and other imaging methods; for definitive diagnosis, histopathologic evaluation is crucial. Surgical resection is the treatment of choice, and results of postoperative biochemical testing can reveal recurrence. Because of this lesion's familial association, genetic testing is suggested. We report the case of an 81-year-old woman who presented with neck pain, intermittent palpitations, hypertension, and dyspnea. Contrast-enhanced computed tomography of the chest revealed a multilobular, high-density lesion between the aorta and the pulmonary artery in the superior mediastinum. The patient's 24-hour urinary vanillylmandelic acid levels were not elevated, which suggested a nonfunctional tumor. Mediastinal exploration revealed a large, vascular, irregular, consistently firm mass that adhered to the aortic arch. Upon histopathologic analysis after complete resection, the mass was determined to be a paraganglioma with a low index of mitosis. The patient had postoperative respiratory insufficiency that necessitated tracheostomy, but she recovered well after rehabilitation. In addition to reporting our patient's case, we discuss the nature, diagnosis, and treatment of paragangliomas.
