Mitral valve repair for degenerative mitral regurgitation with Carpentier's functional classification type II in elderly patients: a single center experience.

Objective: Mitral valve (MV) repair for Carpentier functional classification Type II (C-II) mitral regurgitation (MR) is widely accepted because of its efficacy. It is unclear whether MV repair has the same benefits in elderly patients as in younger patients because of their lower life expectancy. Herein, we examined the midterm results of MV repair for C-II mitral regurgitation, especially in patients aged ≧70 years.

Successful surgical treatment of brachial aneurysm associated with arteriovenous fistula for hemodialysis.

A 58-year-old female who underwent renal transplantation and closure of arteriovenous fistula (AVF) for hemodialysis at age 24 was presented with left forearm pain and cyanosis. Computed tomography revealed an obstructed true brachial aneurysm at the anterior aspect of the elbow joint. Under a diagnosis of true brachial aneurysm associated with AVF, aneurysm resection and brachial to ulnar artery bypass grafting using a reversed great saphenous vein were performed.

Successful Surgical Treatment for Ruptured Aneurysm of Coronary-Pulmonary Artery Fistula Complicated With Cardiac Tamponade.

A 74-year-old woman with no past medical history showed cardiac tamponade caused by rupture of a coronary-pulmonary artery fistula-related aneurysm.

Method and Results A total of 425 patients who underwent TAVR (230 patients) or SAVR (195 patients) were included. Postoperative effective orifice area index (EOAI) was higher in the TAVR group (1.

Unrecognized concomitant ventricular septal rupture and left ventricular aneurysm 10 months after myocardial infarction in a patient presenting with chronic heart failure.

Background: We report a rare case of concomitant inferior left ventricular aneurysm and ventricular septal rupture in a patient presenting with chronic heart failure.

Case Presentation: An 81-year-old man suffered from congestive heart failure. His symptoms were alleviated by medical management; however, heart failure symptoms continued according to the New York Heart Association Functional Classification III.

A rapid aneurysmal formation after late open conversion of endovascular abdominal aortic repair with complete endograft explant.

Late open conversion (LOC) after endovascular aneurysm repair (EVAR) is associated with high morbidity and mortality. Standard surgical technique of LOC has not been established. This report presents a rapid aneurysmal formation in the unreplaced infrarenal aorta after LOC with complete endograft explantation without suprarenal fixations.

Contemporary short-term outcomes of surgery for aortic stenosis: transcatheter vs. surgical aortic valve replacement.

Objectives: This study aimed to compare the short-term outcomes of transcatheter and surgical aortic valve replacements (TAVR and SAVR) in high-, intermediate-, and low-preoperative risk patients.

Methods: A total of 454 patients who underwent TAVR or SAVR were included. Patients were categorized into high-, intermediate-, and low-risk according to the Society of Thoracic Surgery-Predicted Risk of Mortality score and clinical outcomes were compared between TAVR and SAVR groups.

[Risk Analysis of Acute Kidney Injury after Cardiac Surgery and Protective Effect by Less Invasive Surgery].

Objective: We aimed to determine the incidence and risk of acute kidney injury (AKI) in patients after cardiac surgery, and to assess the effects of less invasive cardiac surgery on the prevention of postoperative AKI.

Methods: We retrospectively analyzed perioperative parameters in patients who underwent cardiac surgery. Risk factors for AKI were determined using univariate and multiple logistic regression models.

Anomalous Origin of Left Coronary Artery From Aortic Arch Associated With Hypoplastic Left Heart Syndrome.

Anomalous origin of the coronary artery from the aortic arch associated with hypoplastic left heart syndrome is an extremely rare anomaly. Coronary anomalies can significantly deteriorate the clinical outcomes of hypoplastic left heart syndrome. We describe the case of a newborn with concomitant hypoplastic left heart syndrome and abnormal origin of the left coronary artery arising from the distal aortic arch.

Reoperation for a giant arch anastomotic pseudoaneurysm eleven years after total arch replacement with island reconstruction.

Background: The long-term effects of some surgical treatment procedures of arch replacement for aortic dissection or aortic aneurysm are unknown.

Case Presentation: The present study reports the case of a 68-year-old man admitted to our hospital for aortic arch anastomotic pseudoaneurysm with concomitant aortic root enlargement and coronary artery stenosis. Eleven years ago, at the age of 56 years, he underwent total arch replacement with island reconstruction for chronic aortic dissection.

Surgical treatment for endocardial radiofrequency ablation-resistant sustained monomorphic ventricular tachycardia with mural thrombus including dense calcification in the left ventricle.

Catheter ablation provides effective results for sustained monomorphic ventricular tachycardia (VT), but the presence of mural thrombus including dense calcification occasionally causes unfavorable outcomes. The case of a 67-year-old man in whom sustained monomorphic VT, which was resistant to endocardial radiofrequency ablation, in the presence of mural thrombus including dense calcification after coronary artery bypass grafting was successfully treated by left ventricular reconstruction with cryoablation is reported.

Infantile hypophosphatasia combined with vitamin B6-responsive seizures and reticular formation lesions on magnetic resonance imaging: A case report.

Background: Hypophosphatasia (HPP) is a rare genetic disorder characterized by rachitic bone manifestations and a low serum alkaline phosphatase (ALP) level. It is caused by mutations in the tissue non-specific alkaline phosphatase (TNSALP) gene, which encodes the tissue non-specific isozyme of ALP. HPP patients exhibit various presentations depending on their age at onset, such as infantile HPP combined with vitamin B6-responsive seizures.

Short- and long-term results of radial artery and saphenous vein grafts in the right coronary system: a propensity-matched study.

Purpose: The selection of optimal grafts for the right coronary artery remains controversial. This study aims to evaluate the short- and long-term results of radial artery (RA) grafts and saphenous vein grafts (SVGs) to the right coronary artery.

Methods: We reviewed, retrospectively, isolated coronary artery bypass grafts, placed between 1997 and 2007, and compared the long-term results of patients who received RA (n = 110) grafts with those of patients who received SVGs (n = 264) using propensity-score matching for risk.

Congenital Absence of One Pulmonary Valve Cusp With Other Hypoplastic Cusps.

Congenital absence of a single pulmonary valve cusp is extremely rare. We report a case of a 38-year-old woman with a confirmed congenital absence of a single pulmonary valve cusp associated with dextrocardia. The other 2 leaflets were moderately hypoplastic, and transthoracic echocardiography showed severe pulmonary regurgitation.

Complications and surgical conversion after total aortic repair using endovascular repair in patients with Marfan syndrome.

We report a case of a Marfan syndrome patient who developed a complicated clinical course after total aortic repair using a hybrid technique. After hybrid total aortic repair, this patient was required to undergo open thoracic and thoracoabdominal aortic repair due to impending rupture of the aorta. Moreover, the abdominal aortic graft was rereplaced due to debranching graft occlusion of the coeliac artery and the left renal artery.

Paraplegia due to intramedullary hemorrhage after mitral valve repair.

We report the case of a patient who developed paraplegia after mitral valve repair and maze procedure. The first day after surgery, marked weakness of both lower extremities was noted. Neurologic examination showed almost complete loss of sensory and motor function below the level of the first thoracic vertebrae.
