1/17. Right lateral transthoracic approach mimicking standard transesophageal echocardiographic views in a patient with giant left atrium.We describe the case of a patient with long-standing severe mitral periprosthetic regurgitation and a giant left atrium. The patient was referred for surgery. On the third postoperative day, after resuture of the dehiscence of the valve sewing ring, the patient complained of dyspnea. Transthoracic ultrasound examination was performed to eliminate pleural effusion. The severe right lateral displacement of an aneurysmatic left atrial cavity contacting with the thoracic wall allowed us to obtain excellent images of the posterior cardiac anatomy by a right lateral thoracic view. The new transthoracic approach made it possible to safely assess the atrial side of the mitral prosthesis, eliminating mitral regurgitation after surgery without transesophageal echocardiographic examination.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/17. mitral valve replacement through a giant left atrial appendage.We report a rare case of a 45-year-old male with a giant left atrial appendage (13x10 cm in size) and chronic massive regurgitation at the mitral valve. Massive dilatation was compressing most of the left lower lobe and the large size of the appendage was pushing the mediastinum to the right. Therefore under median sternotomy, the mitral valve was clearly accessible and chordal sparing mitral valve replacement with left atrial plication was successfully performed through the giant left atrial appendage.- - - - - - - - - - ranking = 1.2keywords = giant (Clic here for more details about this article) |
3/17. Autotransplantation procedure for giant left atrium repair.BACKGROUND: Giant left atrium has been associated with bronchopulmonary and left ventricular compression [Kawazoe 1983]. CASE REPORT: We present a patient with severe congestive heart failure (CHF), respiratory insufficiency and a giant left atrium (GLA) following two previous mitral valve procedures and tricuspid valve annuloplasty in the distant past. Mitral prosthetic function and ventricular systolic function were felt to be normal leading to a tentative diagnosis of diastolic restriction from left ventricular compression and pericardial constriction. A pericardial decortication procedure through left thoracotomy was initially done but proved ineffective. Subsequently, full evidence of hemodynamic failure due to the giant left atrium and its respiratory complication was recognized and the patient underwent cardiac autotransplantation procedure [Kosak 1987], with the aim to reduce the left atrial dimensions to normal. CONCLUSIONS: Calcification of posterior left atrial wall prevented a completely satisfactory reduction of atrial size and the severity of ventricular adhesions from the previous pericardial procedure resulted in very long cardiopulmonary bypass time with severe bleeding complications. This case provides ample evidence that GLA can cause respiratory failure and needs to be surgically corrected.- - - - - - - - - - ranking = 1.2keywords = giant (Clic here for more details about this article) |
4/17. silver-coated prosthetic heart valve: a double-bladed weapon.A St. Jude Medical Silzone was implanted in a 72-year-old female, suffering from mitral valve disease. Four months later, the patient had acute cardiac failure due to partial detachment of the prosthetic valve. The mitral annulus was ulcerated and there were multiple erosions in the myocardial tissue in contact with the prosthetic valve. Histological examination revealed chronic inflammation with hemosiderine deposits and giant cells. No allergy to silver ions was found. The silver-coated sewing cuff had caused a chronic inflammatory reaction due to a toxic reaction to silver. The Silzone valve was withdrawn from the market on January 2000.- - - - - - - - - - ranking = 0.2keywords = giant (Clic here for more details about this article) |
5/17. Left atrial reduction and mitral valve replacement in a 5-year-old girl with severe mitral regurgitation and giant left atrium.Giant left atrium associated with mitral valve disease has been implicated in the morbidity following mitral valve repair or replacement. Various methods including left atrial plication have been described to reduce the size of left atrium. Herein we describe our technique of left atrial reduction in a 5-year-old girl with severe mitral regurgitation and giant left atrium. She underwent mitral valve replacement and circumferential left atrial reduction with successful outcome.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
6/17. Thrombosed giant left atrium mimicking a mediastinal tumor.A patient with rheumatic heart disease, mitral stenosis, and mitral insufficiency is described. The thrombosed giant left atrium paralyzed the left vocal cord and completely obstructed the bronchi to the middle and lower lobes of the right lung. The giant left atrium mimicked a mediastinal tumor on the chest x-ray film.- - - - - - - - - - ranking = 1.2keywords = giant (Clic here for more details about this article) |
7/17. Unusually large left atrial myxoma presenting with severe mitral valve obstruction symptoms.A 13-year-old girl with the complaint of severe mitral valve obstruction symptoms was diagnosed as having an unusually large left atrial tumor by echocardiography. The giant mass was surgically removed and the postoperative course was uneventful. Histologic examination confirmed the mass was a benign atrial myxoma.- - - - - - - - - - ranking = 0.2keywords = giant (Clic here for more details about this article) |
8/17. Giant left atrial myxoma in a patient with mitral insufficiency: case report.We describe a 57-year-old female patient with left atrial giant myxoma and peroperative defined mitral insufficiency who underwent surgery with a diagnosis of a left atrial myxoma without accompanying mitral insufficiency. Although no clinical findings of mitral insufficiency were noticed preoperatively, after myxoma resection moderate mitral insufficiency was observed during surgery. Mitral insufficiency was repaired with annuloplasty. The patient recovered without complication.- - - - - - - - - - ranking = 0.2keywords = giant (Clic here for more details about this article) |
9/17. Giant left ventricular pseudoaneurysm after mitral valve replacement and myocardial infarction.Left ventricular pseudoaneurysm is a rare but serious complication of mitral valve replacement or myocardial infarction. Prompt surgical correction is mandatory in cases of a large left ventricular pseudoaneurysm. A 70-year-old man had a giant left ventricular pseudoaneurysm after myocardial infarction and mitral valve replacement. The orifice of the pseudoaneurysm was closed with an e-polytetrafluoroethylene patch and the pseudoaneurysmal wall was almost resected.- - - - - - - - - - ranking = 0.2keywords = giant (Clic here for more details about this article) |
10/17. mitral valve replacement in a patient with a collapsed lung and a giant abscess.mitral valve replacement was performed on a 75-year-old man with a history of pulmonary tuberculosis. Computed tomography showed a collapsed left lung and counterclockwise rotation of the heart due to a hard abscess. Surgery was performed through a median sternotomy, and extensive pericardial suspension was useful for obtaining an adequate view. Despite poor pulmonary function, the patient was extubated on the day of surgery and had an uneventful postoperative course. Cardiac surgery can be performed in patients with a single functional lung if their preoperative respiratory function is good enough to have daily life without dyspnea.- - - - - - - - - - ranking = 0.8keywords = giant (Clic here for more details about this article) |
