Surgical outcomes and strategy of hypertrophic obstructive cardiomyopathy.

OBJECTIVE: To evaluate the surgical clinical results of hypertrophic obstructive cardiomyopathy. METHODS: We 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. RESULTS: One 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. CONCLUSION: Our 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.

Mitral valve reoperation through the left atrial appendage in a patient with mesocardia.

We report the case of a patient with mesocardia, mitral restenosis, and mitral regurgitation. He had undergone an open mitral valvotomy 4 years earlier and, therefore, presented us with a problematic approach to the mitral valve. In such cases, access to the mitral valve is almost impossible due to the position of the valve, which is more posterior and to the left of a normal valve, and due to adhesions from the previous surgery We approached the mitral valve through the left atrial appendage and replaced the mitral valve with a mechanical prosthesis.

Nocardia asteroides mediastinitis complicating coronary artery bypass surgery.

A 63 years diabetic male was admitted with mediatinitis and sternal dehiscence. Nocardia asteroides sensu stricto Type VI was isolated from the mediastinal tissue and fluid during debridement. Prompt surgical intervention and treatment with ofloxacin both intravenously and later orally led to the cure.

Absent pulmonary valve syndrome with aortic regurgitation in a 50-year-old man.

A 50-year-old man was diagnosed as having absent pulmonary valve syndrome with aneurysmal dilatation of the pulmonary arteries. He also had a large subaortic ventricular septal defect and severe aortic regurgitation. He underwent successful intracardiac repair and aortic valve replacement. This case is presented in view of its rarity and controversies in the surgical management.

Transmyocardial laser revascularization: early results and 1-year follow-up.

BACKGROUND: Transmyocardial revascularization using a high-energy CO2 laser has emerged as a new therapeutic option for patients with severe diffuse coronary artery disease refractory to conventional modes of therapy. METHODS: From December 1994 to September 1997, 102 patients underwent isolated transmyocardial revascularization. The mean age was 56.7 +/- 9.2 years and 92.15% were men. Mean preoperative angina class and ejection fraction were 2.6 +/- 0.7 and 44.7% +/- 10.5%, respectively. Diabetes was present in 49.01% of patients, 32.3% had history of previous myocardial infarction, and 12.7% had undergone a previous coronary artery bypass graft procedure. An average number of 23 +/- 8 channels were created in each patient using an 800-W CO2 laser. RESULTS: The early mortality was 14.7% and univariate predictors of mortality were age more than 55 years, female sex, creatine kinase more than 1,600 IU, absence of intercoronary collaterals, and mean pulmonary artery pressure greater than 21 mm Hg. At 1-year follow-up there was significant improvement in angina class and effort tolerance but no significant change in left ventricular ejection fraction. CONCLUSIONS: We conclude that transmyocardial revascularization provides symptomatic benefit and improves exercise tolerance in a group of patients suffering from disabling angina not amenable to other modes of treatment. The high early mortality can be brought down with strict patient selection criteria. The mechanism of beneficial effects is uncertain and patency of laser channels is controversial, but laser-induced neoangiogenesis is being looked on as a possible explanation.

Heart-lung transplantation in India: initial experience.

Heart-lung transplantation is a well accepted and standard form of therapy for the surgical management of patients with end-stage cardiopulmonary disorders. The first heart-lung transplant in India was performed at our institution on May 3, 1999 and, subsequently, 2 more patients have undergone this procedure. The initial experience is encouraging and heralds a new era of thoracic organ transplantation in India.

Clinical course after mitral valve replacement.

Two hundred and fifty patients underwent mitral valve replacement for rheumatic valvular disease during a 9-year period from January 1979 to December 1987. A maximum period of follow-up of 10 years and minimum of 1 year was achieved with a mean duration of 4.4 years. The follow-up covered 921 out of a possible 1006 patient-years and was 91.5 per cent complete. Of the patients, 58 (23.2%) were in class II, 145 (58%) were in class III and 47 (18.8%) belonged to class IV. The early mortality for patients in Class II, III and IV was 8.6 per cent, 15.8 per cent and 31.9 per cent respectively and the 3, 5 and 10 years actuarial survival rates for the entire group were 93 per cent, 87 per cent and 70 per cent. The event-free survival rates at the same intervals were 77 per cent, 63 per cent and 57 per cent respectively. Late deaths occurred in 18 (9.5%) of the patients. Twelve of these (66.6%) could be directly ascribed to a valve-related cause.
