ABSTRACT

OBJECTIVES: The aim of this study is to analyze long-term results of the total aortic arch replacement with the frozen elephant trunk technique for primary chronic type B aortic dissection. METHODS: Among 322 patients who had the frozen elephant trunk technique, 43 (13.4%) patients (median age, 64.0 years) with primary chronic type B aortic dissection were analyzed. The patients underwent surgery at a median of 27.0 months after the onset of aortic dissection. The false lumen was patent in 30 (69.8%) patients preoperatively. RESULTS: Two patients suffered paraplegia and another died of cerebral infarction. Complete thrombosis of the peri-stent false lumen was achieved in 36 (83.7%) patients. Overall survival, freedom from aortic events, and freedom from aortic reintervention were 83.5%, 37.2%, and 42.2% at 5 years, respectively. Survival rates of the patients with or without aortic events were 75.0% and 95.8% at 5 years (Log-rank, p = 0.22). Late aortic events occurred in 19 (44.2%) patients including distal stent graft-induced new entry, type Ib endoleak, and false lumen dilation. The ratio of the stent graft diameter to the preoperative short axis diameter of the true lumen (hazard ratio, 1.90; 95% confidence interval, 1.01-3.59), and the maximal diameter of a postdissection aneurysm (1.07; 1.01-1.12) were the significant multivariate risk predictors of late aortic events. CONCLUSIONS: Late aortic events occurr fairly frequently, and new strategies need to be explored to enhance the effectiveness of this procedure in the future.

ABSTRACT

BACKGROUND: Perigraft seroma is a persistent and sterile fluid confined within a fibrous pseudomembrane surrounding a graft that develops after graft replacement. Development of perigraft seroma is an uncommon complication that occurs after the surgical repair of the thoracic aorta using woven polyester grafts. mechanism underlying perigraft seroma formation remains unclear. CASE PRESENTATION: Herein, we describe the case of 77-year-old man who underwent repeat sternotomy for the treatment of large perigraft seroma 1 year after ascending aorta replacement for acute type A dissection. After removing a cloudy yellow fluid, we covered the prosthetic graft with fibrin glue and wrapped it with a new graft. Bacterial culture and laboratory examination of the fluid confirmed the final diagnosis of perigraft seroma, and there was no evidence of recurrence. The area in which fluid accumulated around the graft shrunk 1 year after surgery. CONCLUSIONS: The cause of a expanding perigraft after repair of the thoracic aorta remains unknown. Physicians should be aware that chronic expanding mediastinal seroma with Dacron grafts is one of the rare postoperative complications of thoracic aortic surgery. Applying fibrin glue to the graft surface might effectively prevent the recurrence of perigraft seroma.

ABSTRACT

Mitral annular calcification (MAC) is a common finding, especially among the elderly. Caseous calcification of the mitral annulus (CCMA) is a rare variant of MAC. Calcified amorphous tumor (CAT) is an extremely rare non-neoplastic cardiac tumor accompanied by calcification and is often associated with MAC. We encountered two patients with end-stage renal failure in whom a cardiac CAT developed on the mitral annulus. In both patients, preoperative examination showed MAC of the posterior mitral annulus and a mobile mass attached to the MAC. CAT and CCMA were considered, and surgical resection was performed because of a high risk of systemic embolization. Intraoperatively, the mobile mass was associated with the CCMA. The CCMA with the mass was entirely removed, and the diagnosis of CAT was histologically confirmed. We herein report these two cases of CAT arising from CCMA in patients undergoing hemodialysis and propose the characteristic imaging features and operative findings.

ABSTRACT

A 44-year-old man was admitted to our hospital with chest pain. We diagnosed him with pericardial effusion collection because of a spontaneous ruptured coronary aneurysm of 1.5 cm with coronary pulmonary arterial fistula (CPAF) by enhanced computed tomography and angiography. We completely resected the ruptured aneurysm and safely closed the CPAF. Rupture of coronary aneurysms with CPAF is rare, especially tiny aneurysms. In previous reports, most cases were older women and the diameter of the ruptured aneurysms was greater than 3.0 cm. We report a case of a middle-aged man with a tiny ruptured coronary aneurysm with CPAF.

ABSTRACT

Papillary muscle rupture is a rare complication after myocardial infarction and almost all cases occur in the mitral valve papillary muscle. Tricuspid regurgitation development after right ventricular myocardial infarction caused by papillary muscle rupture is extremely rare.  In this video tutorial we present a 70-year-old man with massive tricuspid regurgitation caused by papillary muscle rupture after percutaneous stenting of the right coronary artery. We performed tricuspid valve repair with reimplanted papillary muscle in situ using neither artificial chordae nor a prosthetic valve. There are no previous case reports of this surgical repair technique.

Papillary muscle rupture is a rare complication after myocardial infarction. Almost all cases occur in the papillary muscle of the mitral valve. The development of tricuspid regurgitation after right ventricular myocardial infarction caused by papillary muscle rupture is extremely rare. We present a 70-year-old man with massive tricuspid regurgitation caused by papillary muscle rupture after percutaneous coronary intervention to the right coronary artery involving a stent. We performed tricuspid valve repair with a reimplanted papillary muscle in situ using neither artificial chordae nor a prosthetic valve. Previous case reports on this surgical repair technique are not available.

ABSTRACT

OBJECTIVES: Postoperative left pulmonary artery (PA) or bronchus compression occasionally follows narrowing of the retroaortic space after the Norwood procedure. We examined hypoplastic left heart syndrome (HLHS)-specific anatomical malformations and hypothesized that a long main pulmonary arterial trunk might contribute to a larger retroaortic space. In this study, we introduced a modified Norwood procedure [pulmonary artery trunk-saving method (PATS)] and evaluated the results. METHODS: HLHS-specific anatomical malformations were examined using computed tomographic data from 23 consecutive patients who underwent bilateral pulmonary banding. Fourteen patients had HLHS or associated conditions (Group H), and 9 patients had other complex cardiac defects and underwent biventricular repair (Group B). Five consecutive HLHS patients underwent PATS as a modified Norwood operation, and 6 controls underwent a conventional Norwood procedure. We used computed tomography to measure the lengths of the aorta and PA and the angle of both pulmonary branches to evaluate the effect of PATS. RESULTS: Preoperative examination confirmed HLHS-specific right PA branching adjacent to the pulmonary valve and a trend towards a shorter main pulmonary arterial trunk with the conventional Norwood procedure. Also, both right and left pulmonary arterial branching from the dorsal aspect of the main pulmonary arterial trunk and the PA branch angle were minimal in HLHS patients. Postoperative data showed the retroaortic space behind the reconstructed neoaorta was significantly wider in PATS patients than in conventional Norwood patients. Longitudinal measurements (between the aortic arch and pulmonary valve) and sagittal measurements (ascending aorta to descending aorta) were larger in PATS patients, and no left PA or airway obstruction was observed following PATS. CONCLUSIONS: PATS resulted in a wider aortopulmonary space without left pulmonary arterial stenosis or bronchus obstruction. HLHS-specific anatomical malformations suggested that PATS may avoid extrinsic compression of the left PA and bronchus by the neoaorta and can be an alternative for HLHS patients.

ABSTRACT

A 81-year-old man consulted our hospital because of an abnormal shadow on a chest radiography in the right lower field. Computed tomography of the chest showed a mass shadow measuring 41 mm in diameter in the lower lobe of the right lung. There was no lymph node swelling in the hilum or mediastinum. A diagnosis of the lung cancer was suspected and the patient underwent right lower lobectomy with standard nodal dissection. Microscopically, the tumor revealed the epithelial component mimicking fetal lung tissue and proliferative mesenchymal component consisting of immature and heteromorphic nuclear cells as well. The final diagnosis was pulmonary blastoma classified as pathological stage IIB. He was not scheduled for adjuvant chemotherapy due to his older age.

ABSTRACT

We report a case of calcified amorphous tumor (CAT) of the heart in a 60-year-old Japanese man on hemodialysis. Because the masses in the mitral annulus developed during two-year echocardiographic follow-up, he underwent surgical resection with mitral valve replacement. Histological examination showed that the tumor contained multiple calcified nodules, which confirmed the diagnosis of CAT. This case report reinforces the need to deeply and periodically investigate for cardiac involvement of CAT in all patients on hemodialysis.

ABSTRACT

A 76-year-old man was admitted to a community hospital due to a persistent high fever. He became afebrile after the administration of broad-spectrum antibiotics, but developed heart failure due to progressive aortic and mitral valve insufficiency and was transferred to our hospital. Although sequential blood cultures were negative, a broad-range polymerase chain reaction targeting the bacterial 16S-rRNA gene followed by the direct sequencing of whole blood revealed spa(+), mecA(-) and Panton-Valentine leukocidin (PVL)(+). He was finally diagnosed with infective endocarditis (IE) caused by PVL-producing methicillin-susceptible Staphylococcus aureus (MSSA), and underwent cardiac surgery. This is the first reported case of IE due to MSSA producing PVL.

ABSTRACT

Cardiac lipomas are extremely rare benign tumors. They usually remain asymptomatic and are detected incidentally. We report an unusual case of a 60-year-old man who presented with a large epicardial lipoma found unexpectedly during coronary artery examinations. Coronary angiography revealed advanced 3-vessel coronary artery disease. We successfully performed simultaneous curative surgery for the large cardiac lipoma and coronary artery bypass grafting. Histopathology confirmed the diagnosis of lipoma; it weighed 450 g and had a stalk connected to the left atrium.

ABSTRACT

A 69-year-old man with a history of infectious abdominal aortic aneurysm, which had resulted in removal of the infrarenal abdominal aorta and bilateral axillofemoral bypass 9 years previously, underwent total arch replacement for an aortic arch aneurysm. The patient had the interrupted abdominal aorta and highly atherosclerotic proximal aorta, which precluded the possibility of endovascular stent grafting in combination with arch vessel debranching technique. Therefore, open arch repair was the only treatment option. The operation was successful with his axillofemoral bypass graft being exposed and used for arterial inflow during cardiopulmonary bypass, including integrated selective antegrade cerebral perfusion.

ABSTRACT

Discrete subaortic stenosis (DSS) is uncommon in adults after surgical correction of congenital heart defects. There are only a few published reports on the occurrence of DSS in adults. We present an adult case with DSS after repair of a ventricular septal defect (VSD). The case was a 44-year old female patient who underwent VSD closure at 7 years of age. Thirty-seven years later, she presented with congestive heart failure associated with severe subaortic membranous stenosis and atrial fibrillation (AF) that required surgical repair. We report successful surgical treatment of this adult patient with DSS and AF 37 years after repair of a VSD.

ABSTRACT

OBJECTIVES: Atherosclerosis has been identified as a risk factor for both morbidity and mortality in patients undergoing coronary artery bypass grafting (CABG). To investigate outcomes following CABG for severe atherosclerosis, and to determine whether different surgical techniques can reduce the risk of neurologic events in these patients. METHODS: We studied 225 consecutive patients who underwent elective isolated CABG. Routine preoperative and intraoperative examinations identified patients with severe atherosclerosis. We compared the outcomes between patients with (group A; 42 ceses) and those without (group N; 183 cases) severe atherosclerosis. RESULTS: 36 patients (85.7%) in group A and 176 (96.2%) in group N underwent off-pump coronary artery bypass (OPCAB); 6 (14.3%) in group A and 7 (3.8%) in group N underwent on-pump beating CABG. Three patients in group A suffered deep sternal infection (7.1%), and one suffered stroke (2.4%) compared with none in group N. No cerebral infarction or neurologic events occurred in patients who underwent OPCAB (n = 212, 94.2%). CONCLUSIONS: Prevalence of complications was significantly greater among patients with severe atherosclerotic disease who underwent OPCAB than in those without atherosclerotic disease. Careful selection of surgical strategies can prevent perioperative stroke and reduce mortality.

ABSTRACT

We report a 79-year-old patient who presented with a fever and abdominal pain. The patient was initially thought to have a retroperitoneal fibrosis or inflammatory abdominal aortitis in a normal-sized caliber aorta. Broad-range polymerase chain reaction (PCR) and DNA sequencing revealed the presence of Enterobacter. We finally diagnosed nonaneurysmal infectious aortitis, and we performed a successful surgical resection. Establishing a diagnosis of aortic infection before formation of an aneurysm is difficult. The molecular diagnostic technique was particularly useful in specifying the microbial species and diagnosis.

ABSTRACT

We report the successful surgical treatment of a case of aortic valve destruction and pseudoaneurysm of the sinus of Valsalva associated with infective endocarditis (IE) in an 80-year-old woman. Multidetector-row computed tomography revealed an abnormal cavity in the left posterior aortic root. We had made the diagnosis of the aortic valve destruction and saccular pseudoaneurysm of the sinus of Valsalva associated with IE. Aortic valve replacement and patch plasty of the left sinus of Valsalva was performed successfully. A histopathologic examination of the resected aortic valve leaflet revealed inflammatory changes consistent with IE. We describe the surgical technique used in this rare case of pseudoaneurysm of the sinus of Valsalva resulting from IE.

ABSTRACT

We report successful surgical management of a 26-year-old man with a ball-shaped thrombus of the tricuspid valve. He had been treated with prednisolone for IgA nephropathy and undergone surgical closure of an isolated ventricular septal defect (VSD). No symptoms, coagulative disorders, or pulmonary embolisms were found. Preoperative echocardiography showed a ball-shaped mass that had originated from the anterior leaflet of the tricuspid valve; it also revealed a small residual VSD. A histological examination revealed the mass to be an organized thrombus with no tumor components. This was a rare case of excision of an organized thrombus of the tricuspid valve. The findings suggest that the thrombus formation may have been associated with the small shunt and/or prednisolone.
