In this issue of Heart India, we publish six original research articles and one case report. In the first original research article, Gupta et al. have studied the prevalence and determinants of white-coat hypertension (WCH) in medical personnel in prospective manner. WCH is said to be present if a person has an elevated blood pressure (BP) in clinical settings, but normal BP when recorded out of medical setup. A total of 354 medical students were screened for hypertension, and those who were found hypertensive were then subjected to ambulatory blood pressure monitoring (ABPM). Baseline characteristics were compared between white-coat hypertensive and true hypertensive groups. The authors of this study have concluded that WCH is high in young population, especially among medical professionals. The prevalence of WCH is 66%, which is significantly high as compared to the literature available. Reverse dipping on ABPM is strongly associated with true hypertension.
Radial artery anomalies are relatively common and one of the major causes of transradial procedure failure. These anatomical variations of radial artery are known to have geographical heterogeneity, and there are limited data from India. In the second original research article, Khanra et al. have assessed the incidence of radial axis anomalies in patients undergoing transradial cardiac catheterization and their impacts on procedural failure. The authors of this study have concluded that radial artery anomalies are common and are related to significant procedural failure. Retrograde radial arteriography helps identify patients with unfavorable radial artery anatomy, which can be performed with a minimum amount of contrast and should be considered part of a routine transradial procedure.
In the third original research article, Kumar et al. have compared del Nido cardioplegia with St. Thomas's cardioplegia for myocardial protection in adult open-heart surgery. The authors of this study have concluded that del Nido cardioplegia is associated with lower bypass and cross-clamp time, less dose and repetition of cardioplegia, and early return of cardiac activity as compared to St. Thomas solution. Rheumatic mitral stenosis (MS) poses substantial burden in developing countries and is an important cause of cardiovascular morbidity. Speckle-tracking echocardiography is a novel technique, which assesses the left and right ventricular (RV) mechanics and deformation by gray scale imaging. In the fourth original research article, Vijay et al. have assessed the left and RV strain and deformation in patients with severe rheumatic MS to analyze the subclinical ventricular dysfunction in these patients as compared to healthy controls and to see the effect of balloon mitral valvotomy (BMV) on these parameters.
The authors of this study concluded that LV and RV strain and deformation is reduced in severe MS patients. Two-dimensional speckle-tracking echocardiography can detect these early changes in LV and RV function before overt systolic dysfunction. BMV significantly improves LV/RV strain and deformation at early and short-term period.
Congenital heart disease (CHD) refers to the presence of a structural abnormality of the heart and/or great vessels, which is present at birth and is of actual or potential functional significance. In the fifth original research article, Mansoori et al. have retrospectively studied the surgical outcomes of various CHDs at tertiary care center. Tissue Doppler imaging (TDI) is a sensitive, noninvasive, echocardiographic technique that uses the Doppler principle to measure the velocity of tissue motion within the myocardium. It helps in the quantitative assessment of both global and regional functions of the myocardium. This technique helps in the detection of subclinical and clinical left ventricular (LV) systolic and diastolic dysfunction (DD) and timely identification of the risk factors. In the sixth original research article, Kurapati et al. have studied the efficacy of TDI in diagnosing systolic and DD and comparison to the conventional methods of LV function assessment in heart failure (HF) patients. The authors of this study concluded that TDI parameter “Ea” was the most powerful predictor of LVDD when compared to “E/A” Doppler echocardiography. LV ejection fraction (EF) was a more powerful indicator of LV systolic dysfunction when compared to Sa of TDI. TDI “Ea” and “Sa” parameters can be helpful as diagnostic, prognostic markers in HF patients with low ejection and normal EF.
Dextrocardia is a rare condition with mirror-image position of the heart. Given the rarity of this condition, percutaneous coronary intervention in dextrocardia can be technically challenging. A modification in catheter manipulation and image acquisition technique is required for a successful procedure. In the last, Rana et al. have reported a case of non-ST elevation myocardial infarction in a 55-year-old male patient with dextrocardia, managed successfully with coronary angioplasty of the right coronary artery through the left transradial route.
