OBJECTIVETo evaluate the surgical clinical results of hypertrophic obstructive cardiomyopathy.

METHODSWe retrospectively collected data on 24 patients who underwent surgical management in the past ten years in two hospitals in China and Madras Medical Mission in India. Myomectomy was carried out on all patients. Among them 3 patients underwent mitral valve replacement; 2 patients underwent mitral valve repair (anterior mitral leaflet plication); 2 patients underwent aortic valve replacement; 1 patient underwent aortic valve repair; 2 patients underwent aortic root replacement; 1 patient underwent Bentall's procedure and 1 patient underwent coronary artery bypass grafting because of a breached muscle bridge.

RESULTSOne patient died of post-operative heart failure. The mean follow-up time was 4.3 years. There was significant improvement in the symptomatic status. Sixteen patients were asymptomatic with good effort tolerance and only four patients had New York heart association (NYHA) Classes I-II due to associated valvular lesions.

CONCLUSIONOur experience proved that symptomatic hypertrophic obstructive cardiomyopathy or non-symptomatic hypertrophic obstructive cardiomyopathy with combined heart disease is indication for surgery as surgical intervention could get better clinical results in this kind of patients compared with other non-surgical method because it beneficially reduces the systolic anterior motion (SAM) of the mitral valve leaflet, which could not be avoided by other non-surgical treatment.

We present a case of successful surgical resection of a giant left ventricular (LV) pseudoaneurysm that developed 5 yr after mitral valve replacement (MVR). A 59-yr-old female was admitted with exertional chest pain radiating to left arm and back. 64-slice multidetector computed tomography (MDCT) revealed significant stenosis on the ostium of the first diagonal branch of the left anterior descending coronary artery and also a huge pseudoaneurysm compressing the right atrium and the inferior vena cava. She underwent resection of the pseudoaneurysm, and the pseudoaneurysm tunnel was repaired from the inside of LV cavity by removing the previously inserted prosthetic valve, followed by redo MVR together with coronary arterial bypass grafting (CABG) for a single-vessel disease. At the 6-month follow-up, the patient continued to do well without any complications.

INTRODUCTIONPapillary muscle rupture and dysfunction can lead to complications of prolapsed mitral valve and mitral regurgitation. Multiple operative procedures of the papillary muscles, such as resection, repositioning and realignment, are carried out to restore normal physiological function. Therefore, it is important to know both the variations and the normal anatomy of papillary muscles.

METHODSThis study was carried out on 116 human cadaveric hearts. The left ventricles were opened along the left border in order to view the papillary muscles. The number, shape, position and pattern of the papillary muscles were observed.

RESULTSIn this series, the papillary muscles were mostly found in groups instead of in twos, as is described in standard textbooks. Four different shapes of papillary muscles were identified - conical, broad-apexed, pyramidal and fan-shaped. We also discovered various patterns of papillary muscles.

CONCLUSIONNo two mitral valve complexes have the same architectural arrangement. Each case seems to be unique. Therefore, it is important for scientists worldwide to study the variations in the mitral valve complex in order to ascertain the reason behind each specific architectural arrangement. This will enable cardiothoracic surgeons to tailor the surgical procedures according to the individual papillary muscle pattern.

Endobronchial balloon tamponade is an alternative method that can be used to control massive hemoptysis. Several different techniques have been used for this purpose. We describe a new parallel method, in which biopsy forceps introduced through a bronchoscope channel is used to grasp a balloon catheter. As the bronchoscope is advanced to the bleeding site, the balloon catheter is pulled into position, and subsequently inflated. There are several advantages of this technique. It needs no specialized catheter or guide wire, the procedure is relatively easy to perform, and applicable to other purposes such as introduction of an additional suction catheter.

Clinical results of minimally invasive mitral valve surgery were retrospectively reviewed, and two different surgical approaches were compared in this study. Between 1997 and 2004, a total of 86 patients with mitral valve disease underwent minimally invasive surgery at theYonsei University Cardiovascular Center. Age of patients averaged 41.6 +/- 14.0 years and 69 patients were female. Surgical approach included low-sternal incisions with mini-sternotomy, and right parasternal or thoracotomy approach. Either direct aortic or femoral arterial and bicaval cannulations were used in all patients. Patients were divided into two groups according to the method of surgical approach (parasternal (P) vs low-sternal (L)), and the results were compared. Postoperative NYHA functional class improved to 1.1 +/- 0.4 in all patients (no significant statistical difference between two groups). Mean wound length (P: 9.21 +/- 1.10 vs L: 11.24 +/- 0.82 cm, p < 0.05), and mechanical ventilation time (P: 10.42 +/- 4.36 vs L: 12.90 +/- 5.00 min, p=0.04) was significantly shorter in parasternal group, and mean operation time(P:294.74 +/- 59.41 vs. L:259.31 +/- 54.36 min, p=0.03) was significantly shorter in low-sternal group. Mean cardiopulmonary bypass time, and aortic cross clamp time was also shorter in low-sternal group without statistical difference. There were 2 minor wound complications in all patients (p=NS), and no hospital death. Comparing the two different surgical approach of minimally invasive mitral valve surgery, parasternal approach is thought to be more beneficial in reducing postoperative scar, and intubation time.

OBJECTIVE: The purpose of this study was to use autopsy to explore cause of death and to identify medical errors after cardiac surgery. METHODS: Clinical and autopsy findings in 6 cases were analyzed with respect to the clinical diagnosis, operation types, death time and features, and autopsy findings, medico-legal disputes and related medical errors. RESULTS: There were total 6 patients. The procedures involve cardiac valve replacement (4), coronary artery bypass (1), and congenital aortic transposition repair (1). Three patients had sudden death one week after surgery and 3 from congestive heart failure. The findings include myocardial infarction (2), massive myocardial injury (1), endocarditis (2), and multi-organ failure (1). The families in all six cases suspected malpractice. The major concerns were operation indication and timing, selection of operation equipment, operative mishandling, inadequate post-operative care and timely therapeutic invention, inadequate informed consent regarding the severity of the disease itself, the risks of heart surgery, and its prognosis after the procedures. CONCLUSION Autopsy can be used to determine the cause of death, to assess the quality of the operation and post operation management, and to help to resolve malpractice disputes
