Case ReportsRight ventricular obstruction in various types of hypertrophic cardiomyopathy.
Hypertrophic cardiomyopathy (HCM) is most probably a genetically transmitted disease with different clinical and hemodynamic features. In hypertrophic obstructive cardiomyopathy (HOCM) the obstruction is predominantly in the left ventricular outflow tract (IHSS). ⋯ Right ventricular hypertrophic obstruction (RVHO) is an uncommon type of HCM and is almost always combined with other types of left ventricular HCM. We describe in the present report 1 case of RVHO with IHSS, 2 cases with MO and, to our knowledge, the first case with AH.

Case ReportsNecropsy finding in a patient with apical hypertrophic cardiomyopathy.
Whether apical hypertrophic cardiomyopathy is a variant of classic hypertrophic cardiomyopathy or a separate entity is controversial. This is a case report of an apical hypertrophic cardiomyopathy. The patient was a 67-year-old man associated with giant negative T waves in electrocardiogram and asymmetric apical hypertrophy on echocardiogram. ⋯ At necropsy the heart showed apical hypertrophy grossly and extensive disarray of myocardial fibers near the apex of the left ventricle histologically. The necropsy findings were indistinguishable from those of classic hypertrophic cardiomyopathy. This suggests that apical hypertrophic cardiomyopathy is a variant of hypertrophic cardiomyopathy.

Case ReportsCoronary spasm as a cause of perioperative myocardial infarction.
The case of a patient with severe left main trunk disease is presented, in which spasm of the right coronary artery resulted in intraoperative myocardial ischemia and perioperative myocardial infarction. It is suggested that coronary spasm may be a cause of perioperative myocardial infarction, and has to be considered in case of unknown etiology.

Effects of metoclopramide, a dopamine antagonist, on secretion of aldosterone and renin release in patients with primary aldosteronism.
To assess the interaction between dopamine and aldosterone secretion in primary aldosteronism, the dopamine antagonist, metoclopramide (methoxy-2-chloro-5-procainamide), was given as an i.v. bolus (10 mg) to 5 patients with primary aldosteronism and 5 normal subjects treated with dexamethasone (2 mg/day) to eliminate an influence of ACTH. Metoclopramide increased plasma aldosterone concentration (PAC) in primary aldosteronism from 39.1 +/- 15.5 to 42.5 +/- 15.9 ng/100 ml (p less than 0.05) and also from 12.9 +/- 2.3 to 23.6 +/- 3.4 ng/100 ml (p less than 0.01) in normal subjects at 15 min. ⋯ It is suggested that dopamine inhibits the secretion of aldosterone in primary aldosteronism as well as in normal subjects. It seems unlikely that dopamine affects the release of renin in primary aldosteronism.

Ventricular septal defect in infancy. Surgical criteria and experience.
The optimal surgical management of ventricular septal defects (SVD) in infancy and particularly in small babies, still remains controversial. Seventy-six infants with VSD as the major cardiac lesion were operated upon from March 1978 to December 1981. Forty-three underwent primary repair with a 9.3% mortality rate. ⋯ Based on our own experience, our current recommendations are as follows: PAB in severely ill infants under 3 months of age, in infants with multiple or "Swiss-cheese type VSD" and in some cases of VSD with associated anomalies. Early debanding and correction, except in cases with multiple VSDs. Primary repair in infants aged more than 3 months and in some selected younger cases, according to the anatomical location of the defect.
